3 comments/ 58255 views/ 31 favorites At My Cabin By: jeffss45 For this story to make any sense, I need to tell you a little bit about myself. I'm a geek; I write computer programs for a living. I'm a rare breed that creates programs for the web and programs known as hardware drivers drivers. Hardware drivers are programs that allow computers to control with other devices like webcams and printers. That will help you understand how I made what has become my favorite masturbation toy. I'm into edging and teasing myself. I used to do this with my hand but I was always looking for something better. So I created myself a toy that edges me. The most complex component of my toy was a butt plug with a pressure sensor. I use this butt plug to determine when I'm about to cum. It took a lot of experimentation to get it right but I now know how hard I squeeze my butt when I cum. Using this information, I developed a program that knows when I will cum. I then added two vibrators. The first was a switch to a vibrating butt plug that will still hold my pressure sensor. The second is a bullet vibe I put on my cock with an elastic ring. The computer is able to adjust the speed of the vibes. Using the information from the pressure sensor on the butt plug, it slows the vibes down as a I get close to cumming. The program can adjust the speed of the vibratrators to keep my on the edge or orgram almost indefinitely. I've had them keep me there for as long as five minutes though that was tough and only when I was still figuring out what the best combination was. The program I created does what I like to call edging cycles. It ramps up the vibrators. When I get close to orgasm, it starts the cycle by keeping me right on the edge. A cycle will last from one to three minutes. The program then turns the vibrators off for 15 seconds to one minute and then repeats the cycle. I also tell the program how long I want to be edged by telling it an minimum and maximum amount of time. It decides how long until I cum. I used my toy this way for as long as 20 minutes. I think it took me through 7 cycles that time. I tried to make the program run longer but I couldn't take it. I ended up stroking myself because I just couldn't take it. In fact, I've had a hard time repeating the 20 minutes. So I added one more thing to my toy; I added a system that ties me up while the program is running. I do this by putting cuffs on my wrists and ankles. The cuffs are connected to cables. The cables are connected to a winch. The winch has a pressure sensor and is controlled by the computer. When the program starts, it pulls the cables taught until I can barely move. The edging cycles then begin. The program now ends by making me cum and then releasing me. I have now done numerous 30 minutes sessions. They are really intense, by the end, I need to cum more than ever. Once the program makes me cum, I'm a quivering mess. And I love it. A few years ago, my aunt gave me a cabin of hers out in the middle of nowhere. Because of her age she couldn't use it any more and she remembers that I loved it. Since then, I go to the cabin a lot. I like that I can go days without seeing another person. And since I've added cable and Internet to the cabin, I spend a lot of time there. On my last trip to the cabin, I decided to bring my toy. It wasn't easy to break it down and move but I managed it. One particullarly gorgeous day there, I decide to setup my toy outside. Just the thought of that has me hard while I'm setting the machine up. After completing the setup, I go back in and get myself ready. When I get back outside, I am naked, wearing four cuffs, have a vibrator attached to my rock-hard cock and have a butt plug. I connect everything and lay down on the blanket. I attach the cables, set the program for a 15 to 25 minute session and then hit start. I was a bit worried 25 minutes was too long because I am outside but it is too late know. As soon as I hit the button, I feel my arms and legs getting pulled. I realize how stupid this idea was but, if anything, that is making me hornier. The vibrators start. It doesn't take long before I'm ready to cum and the computer is keeping me on edge. I must be a site as I start to moan and buck my hips a bit. Being outside is definitely making the feelings more intense. My cock is hard and purple and enjoying every second. The computer keeps running the edging cycles; I've lost count of how many I've gone through already. I start trying to not squeeze the butt plug so that I can fool it into letting me cum. But I can't hold off long enough to cum. Instead, I think this is causing the computer to push me closer than usual. It is excruciating in the best possible way. And then I reach the computer doesn't turn off the vibrators and I cum. I'm almost screaming as I start shooting my cum. My orgasm seems to last for minutes until the vibrators finally turn off. A few seconds later, the cuffs loosen and I get up. The program says it edged me for 18 minutes with 7 edging cycles. I can't believe it was so quick, it felt more intense than the 30 minutes sessions I had been doing. I'm exhausted and head into the cabin to get dressed and take a nap. The next day, I decide to try it again but I want to push it further. I'm going to set the minimum to 30 minutes, the longest I've ever gone. I'm torn on what to make the maximum. Part of me thinks 45, another part of me thinks 60 is better. And a really disturbed part of me wants to try 90. I realize that's a ridiculously long time but I am so excited of the idea of being outside and edged for that length of time, that I seriously consider it. It's getting to late morning and I decide now is a good time to play. So I put on all my stuff and head outside. Like yesterday, I get on the blanket and attach everything. I decide to set the maximum time to 60 minutes. Before I have a chance to think about it much, I hit the start button. I feel the cuffs pulling my arms and legs. When my arms and legs are pulled tight, I feel the vibrators start. I lay back and start enjoying the vibrators. Before much time has passed, the vibrators have brought me to the edge. Like before, the program is expertly keeping me there for what seems like forever. I've gone through I don't know how many cycles, I'm covered in sweat, humping, moaning, and more desperate to cum than I've ever been. That's when I hear them. A woman's voice; she is talking to someone. Another female voice replies. I'm trying to keep silent so that they won't hear me. Another edging cycle starts. And that makes it impossible for me to be totally silent. I'm so desperate to cum that I can't help but to moan quietly and grind my hips. At that moment, they pop out of the woods and see me. I think they think I'm in trouble but as they get closer they get a better idea of what is going on. "Oh my god" one of them exclaims. "What is happening?" In my excited state, I try and explain what my machine is doing. It gets easier when the current edging cycle ends but then, while I'm still explaining things, another cycle starts. But I think that witnessing the cycle begin explains better than I ever could. Especially when they see me start to grind my hips again. They watch me as the machine edges me. One of them asks if I am really that close to cumming. I mumble in reply as my cock starts to twitch. They can't help but stare. That makes me even hotter and I feel the vibrators slow down to keep me on the edge. I'm really moaning now and can't stay still even when the vibrators are off. I'm guessing I've been edged longer than I ever have before. And that's before I consider the effect of being watched. I get asked if they can touch my cock. I manage to say yes and ask them to be careful not to make me cum. I feel fingers massaging my cock head and I can't help but moan because it feels so good. I then hear one tell the other that she thinks I am really, really close to cumming. I look over and see one of them rubbing her pussy through her pants. She is staring at my cock with the most lustful expression I have ever seen while she is masturbating. That makes this whole situation even hotter for me. And then the other women starts masturbating too. Another cycle starts. It only takes a few seconds to be on the edge of orgasm and more desperate to cum than I have ever been in my life. I feel the cycle continue with the vibrators slowing down to prevent my orgasm. I try to look at the women to see what they are doing but I can't concentrate on anything but the feeling of need in my cock. When I next notice, I see one of the women cum. That makes me so horny, the vibes almost stop because I am almost cumming just from seeing and hearing her. I so need to cum but the machine just won't let me. And then the other woman cums. She is much noisier than her friend. She cums just as the cycle ends. The moans escaping her lips keep me on the edge. They both come down off their orgasms and look back at me. I'm still writhing in pleasure and my need to cum. The vibes start again and another cycle begins. It takes me a second to realize I'm being asked a question. "How much longer will this go before you cum?" "I don't know." Turning to her friend, she says "We need to stay". Her friend smiles and shakes her head while I'm busy moaning, humping, and not cumming. This cycle ends and I get down from the edge just a little. I'm laying with my eyes closed hoping the machine will let me cum. I've never needed it so bad. "Wow. I've never seen a cock so swollen and so purple. It's amazing." I hear one of them say. The next cycle begins. Almost instantly, I'm at the edge of my much needed orgasm. I feel the vibes slow down to continue the cycle. I moan in frustration wondering why I made this session last so long. Suddenly, I feel the vibes speed up. It only takes me a few seconds and I cum. The women are watching as my cum starts to fly. My orgasm seems to go on forever. Finally, the vibrators turn off and the ropes loosen. I free myself and stand up. I see no reason to be modest since both of my visitors just watched me have the biggest, most intense orgasm of my life. One introduces herself as Karen. She tells me her friend is Stephanie. They then start heading back to continue their walk. Karen looks back and tells me "Maybe I'll stop by again tomorrow". They head into the woods and I head into my house to clean up. At My Cabin Ch. 02 I woke the next morning horny. All night I kept thinking about being on my masturbation machine while Stephanie and her friend watched. And I kept getting hard thinking about it. Once I was done with breakfast and my normal morning routine, it was 9:00 am. I didn't go out yesterday until close to 11:00 so I don't want to go out too early just in case Stephanie does decide to stop by again. So I do a few things around the house but I kept getting distracted and thinking about my next orgasm. While I was waiting, I make a few changes to the program. First, I change the length of time it keeps the vibrators off between cycles. It now starts at 15 seconds to 1 minute, like before, but adds 10 seconds every time it runs an edging cycle. To keep it from getting too long, I set the range to no more 60 seconds to 150 seconds. Second, I changed the edging cycles. First, the timer doesn't start until I've reached the edge for the first time. Second, it changes to two to four minutes once the off cycle reachs a minimum of 60 seconds. The final change I made is how it lets me orgasm. When I reach the time to cum, it will run an off cycle and then a full edging cycle letting me cum at the end of the edging cycle. And, it will make me cum by running the vibrators just a bit faster than they are in edging mode. I'm not sure how much I'll like this so I make it a parameter so that I can easily change it back. After fighting these thoughts for an hour, I decide to give in and let my machine make me cum. So I get myself ready and head outside. As I'm connecting myself to the machine, Stepahnie shows up. Since I'm not yet in the machine, I get a closer look at her. She's brunette, about 30, and really sexy. Today she is wearing shorts and a tight t-shirt. I'm pretty sure she doesn't have a bra on. "I see you are ready for another round even after that orgasm you had yesterday." "Yes" is all I could think of in reply. "Good, because I want to see you cum again." And she gives me this huge smile. I take that as an invitation and hook myself up to the machine. I decide to set the parameters for the program a bit shorter than yesterday; I go with a 20 minute minimum to a 40 minunte maximum. Stephanie is asking me about how the program works so I'm showing her as I'm setting it up. "Wasn't it a lot longer yesterday?" "Yes" I reply. "Yesterday, I set it from 30 minutes to 60 minutes. It ran for 56 minutes which is the longest I've ever gone." "Why so much shorter today?" "I don't think I could handle two days in a row like that." That seems to satisfy her because she stops asking questions. I feel the cuffs being pulled and I realize she clicked the start button for me. A minute later, I feel the vibrators start. I look over at her, and she watching me and smiling. I feel the vibrators start and it doesn't take long before I'm near orgasm for the first time today. Stephanie is intently watching me which is making me even hornier, just like yesterday. I start to moan as the program starts to edge me for the first time. I notice that Stephanie has moved but I can't really see what she is doing. When the edging cycle finishes, I look around and it takes me a few minutes to spot her. I finally see her sitting on a deck chair, without her shorts and masturbating. She sees me look her way and smiles. The vibrators begin again and the sensations force me to stop watching and close my eyes. As I start to moan from being edged again, I hear Stephanie moaning as well. Then right as the vibrators turn off, I hear her cum. It takes me a second but I look over and see her sitting with her hand in her pussy, and her head thrown back as her orgasm completes. Next thing I know, she is getting up and walking towards me. I'm surprised the vibrators haven't started up again but that must be the new pause rules. As she sits down next to me, I feel the vibrators start. Again, it doesn't take long for the edging to start. I hear Stephanie moan next to me and I manage to look. That's when I see that she is sitting with her legs spread, rubbing her clit right next to me. That's gets me moaning and thrashing in my bonds. OMG she is so hot and I can't cum. The vibrators keep teasing me, making sure I can't cum until suddenly they just stop. When Stephanie notices this, she stops masturbating, letting me see her wet pussy with her clit screaming for attention. I feel the vibrators begin again. As I start to moan, she starts to masturbate again. Too short of a time later, I feel the vibrators turn off. This time, Stephanie doesn't stop and she cums again. I'm able to watch up close. I see her pussy contract in rhythym with her moans. And I am more turned on than ever. I feel the vibrators start up again. I notice Stephanie get up and go back to the deck chair. I see her sit down and start watching me just as the vibrators start edging me and I have to look away. This cycle continues for what feels like forever. I am so very ready to cum but the program won't let me. Now, I think the vibrators have sped up a little bit. My orgasm is getting closer and closer. I'm moaning and gyrating a ton now going crazy with the need to cum. And finally, I start to cum. It goes on for a long time before I feel the vibrators turn off and the cuffs start to loosen. After lying down for another few minutes, I disconnect myself and get up. Stephanie comes over and smiles. "Wow, that was even better than yesterday" she tells me. I just smile back. "Can you make one of those for me?" she asks. I look at her not knowing what to say. "It just looks so exciting. And today I tried to not cum until you did but I couldn't do it. Even after I let myself cum once, I couldn't do it. But I'm dying to try it." "ok, we'll try." I tell her. "I need to order a few things so stop by in a couple of days and we'll get started. Oh, and the hardest part will be calibrating the machine so it knows when you are about to cum. The only way we can do that is for you to cum while attached to the machine. And it will take quite a few orgasms so be ready." With that, she smiles at me, tells me "Okay, that sounds so great" and she heads home. I then head into my house to clean up and get started on ordering those parts. At My Cabin Ch. 03 So, I immediately ordered all of the parts I needed to put Stephanie in the machine. I ordered duplicates of many parts so that we could both be hooked up at the same time. I ordered with next day shipping because I couldn't wait to get started. When the parts showed up, I got busy. I made an entire duplicate of my setup that could hook up to a single computer. I changed the program so that it could support the two machines, making it run the same program on both. We'd experience the exact same timing and everything. It was all I could do to keep going and not stop and use the machine on myself. All that was left was to calibrate the pressure sensor and the vibrators for Stephanie and she'd be ready to go. Thinking about putting Stephanie through her paces to get the machine calibrated was really exciting. It took me about 10 orgasms before I had the machine reliably edging me. Part of me was hoping I'd have to do the same to her because I couldn't see how making her cum couldn't be fun. I did decide though to let her know that it would take quite a few orgasms to get the machine calibrated. At 9:00 am the next morning, Stephanie arrives. I roll out of bed and let her in. I notice right away that she was dressed similarly to the last time I saw her. But this time, I'm positive she isn't wearing a bra. I invite her in and show her the equipment I bought for her. I head into my bedroom to change. When I get back to her, she is checking out the butterfly vibrator. I tell her that my hope is that it will stay in the right spot during a session. She then checks out the butt plug / vibrator with the pressure sensor. "I've never had anything in my butt before". "Neither had I. We'll lube it up and it shouldn't be an issue." I continue talking about what's next. "We need to start by calibrating the pressure sensor. That's how the program knows when you are about to cum. That needs to be right before it can edge you. To callibrate it, you will need to cum two or three times with the pressure sensor inserted." "Ok". "How do you want to do this?" I ask her. "It will probably be easiest if I'm here to run the program. But if you'd rather be alone, I can give you instructions and you can try and do it by yourself" I say praying that she will be okay with me staying. "You can stay. It's not like you haven't already seem me cum" she says blushing. "When you are ready to start, take off your shorts" I say while trying to hide my smile at the thought of her getting naked. She gets right to it and removes her shorts. I start lubing up the pressure sensor butt plug for her. When I'm done, I hand it to her. She asks me to turn around so she can insert the vibe. I turn away and she's inserting the butt plug. When she's done, I turn back and connect the sensor to the computer. I tell her to lay down and to start masturbating when she is ready. She asks me if she can sit and use the rabbit vibe. I tell her that for this, it will work better if she lays down and uses something familiar to her like her fingers. It's then that I tell her that she also needs to tell me right before she is about to cum. And with those last words, she lays down and starts to rub her pussy. I think having me watching and dressed has her a little self-conscious because it takes a while before she gets into it. She starts moaning softly and rubbing a bit quicker. I'm watching the computer, watching her and hard as a rock. The computer is doing what it needs to do so I start watching her more. Before I know it, she screams, "I'm about to cum." I click the button to tell the program that she is about to cum and then watch her cum. It only takes a few seconds before her orgasm has subsided and she is smiling at me. She tells me she is ready to go again and immediately starts rubbing herself. Again, I watch her, watch the computer and get harder still. Again, she screams as she's about to cum and she makes a lot of noise as she cums. This time, when she finishes, she gets up and walks around a bit. She leaves the butt plug in her ass and tells me that she isn't done yet. I look at the program and the readings from her first two orgasms were pretty close. That's a good sign that the calibration readings are fairly accurate. If her third orgasm is in the same range, we should be ready to start working on the vibrator. She is back quickly, asking me if I'm ready for her to go again. She removed her shirt and I see her tits for the first time. They are fantastic; she has wonderful nipples that are hard and that are making me hard again. She lays down and her third orgasm is just like her first two, noisy. The readings are again close so I tell her to take a break before we start the next step. This is going much quicker than I had anticipated. This time, she removes the butt plug and gingerly hands it to me. I head to the bathroom sink and carefully wash it while she is getting dressed. She leaves then, telling me she'll be back later. It takes all I have not to masturbate while she is gone. But I want to wait as I figure that will give me an even more amazing orgasm later. A few hours later, she is back. She walks in and removes her coat. She has nothing else on. She goes straight for the butt plug. I give her the lube, she gets it ready, and inserts it. This time, when she lays back I tell her that we need to use the butterfly vibe. I go get it and show her how to attach it. I tell her that the most important thing is that she position it so that she doesn't have to move it or touch it once we start. She slips the straps on and positions it as best she can. I turn it on briefly to let her adjust it. When I do, she jumps telling me that it is positioned fine. We both smile at that. Again, I tell her to let me know as she is about to cum. With that, I turn to the computer and start the program. The goal this time is to see how well the program can predict when she is about to cum. I see her jump when the vibrator starts. I make a note to have the program ramp the vibrator up slower. I hear her react as the vibrators increase. According to the monitor, she is building up to orgasm quickly. I slow the vibrators down a bit. She is still building up to orgasm quickly. I slow them down some more. Suddenly, she yells, "I'm going to cum" and she starts bucking her hips and moaning even louder than when she came earlier. I'm watching the program because it is keeping the vibrators going until it detects her orgasm has let up. She finally has to tell me to make them stop and I do. I look and notice that the vibrators ran for almost 90 seconds after her orgasm started. While things are fresh in my mind and while she is recovering, I change the settings to, hopefully, streamline the effects a bit. When I'm done, I tell her that we are really close; I think one more test and we will be ready to go. She removes everything and gets up, tellng me she is exhausted and needs to head home. As she's leaving, she thanks me and tells me she'll be back tomorrow morning. I must have jacked off three times that night thinking about our sessions and what is to come. I didn't use my machine because I didn't want to take the time to set it up for me. She shows up again at 9:00 am. This time I was expecting her and was out of bed. I let her in and notice right away that she is wearing the same coat she had on yesterday. Again, she removes the coat and is naked. She doesn't waste any time and heads to the equipment. She puts in the butt plug and lays down to put on the vibrator. "Today, I'm going to have the program try and edge you. We need to make sure it is set right so that it brings you to the edge without letting you cum. I will have to ask you some questions while it is going on so that we can make sure it is adjusted correctly." She smiles and tells me that's fine so I hit the button and we get started. "Make sure you don't touch the vibrators during this. That might be harder to do than yesterday. Also, don't sit up because that will throw off the pressure sensor." I notice right away that the startup of the vibe is better than yesterday; she didn't jump. I notice that she is pretty horny; again her level of excitement is rising quickly. I make an adjustment and the vibrators slow down. The speed change gets her to moan. "How's it feeling" I ask. "Good" she stutters back. I continue watching the settings and continue to make minor adjustments. "The program will start edging you in a minute. It will feel unique and exciting and frustrating all at the same time. Make sure you don't give in and rub yourself." As I thought, less than a minute later the program started an edging cycle. I'm listening to her reaction and making some adjustments. "Are you just about to cum?" I ask. "Yes and no." "Do you think the program should push you further?" I ask. "Yes." So I make an adjustment to let the program push her closer. I hear her moan again and I see her start to move around a bit. I make another adjustment and push it a little too far because she cums and cums hard. I adjust the vibrators to her orgasm and keep her cumming for nearly 30 seconds. Once she finishes, I adjust a few more settings in the prorgram to help it edge her better. When she recovers, I apologize for making her cum so soon. She tells me that I have nothing to apologize for because that was fantastic. "Take a break and we'll try again in a bit." 30 minutes later we are getting ready to try again. I hit the button and the vibrators start. The ramp up is going smoothly. I notice that she isn't getting excited quite a quickly as last time so I make an adjustment to make the vibrators go a bit faster. A minute or so later and the program starts edging her. She is really moaning and moving around. I remind her not to touch herself when I see her hands start to move. This time, the program is successfully keeping her on the edge of orgasm. And she seems to really enjoy it. After two minutes of edging, I tell the program to shut the vibrators down for 30 seconds followed by another two minute edging session. "How did that feel? " I ask right as the vibrators are turning off. "Wow." "Just wait a few seconds and another edging session will start." "Wow. I've never felt anything like this before." Before too long, the vibrators start again. It doesn't take long before she's moaning and grinding. Again, the program edges her for two minutes. When the cycle is over, I tell the program to make her cum. And cum she does. She has one of the strongest and longest orgasms I've ever seen. Watching her cum, I know the adjustments in the program are perfect. After laying still for a few minutes, she sits up and disconnects herself from everything. "Wow, that was great. I've never cum so hard in my life. I see you enjoyed it too." she says while looking at me. Her comment makes me realize that I'm staring at her with a dumb smile on my face. "I think I've got the program adjusted well. We can try a full cycle tomorrow." I tell her because I can't think of anything else to say. Especially since I'm still hard as a rock and I don't want to get up and ruin the moment. After another minute, she gets up and walks over to me. "Now it is your turn" she tells me as she pulls me to a standing position. She pulls down my pants and starts to gently stroke my cock. She guides me over to a sofa by my cock and lays me down. She then puts my cock into her mouth and gives me what was one of the best blow jobs I'd ever had. I cum and cum hard, shooting deep into her throat. She swallows my cum and keeps my cock in her mouth for an extra minute. When I'm soft, she lets my cock fall out of her mouth and gets up. She heads towards her coat and puts it on. "I'll be back tomorrow, same time" she smiles at me as she heads out the door. At My Cabin Ch. 04 It's 8:45 the next morning and I'm anxious for Stephanie to show up. I have everything ready so that she can get into the machine for the first time. I don't want to put myself into the machine too so that I can monitor the program though I really wish I was going in too. And, after yesterday's experience, I expect this to work well. I think about Stephanie some more and realize I love these sessions with her but I don't know anything about here. I don't know why she keeps running out so quickly afterwards. Yesterday was the first time she stayed at all but she ran out as soon as she finished giving me a blowjob. Not that I'm complaining. After all, it was a great blow job. And I just love to watch her cum. I think she is just using me for sex. I can live with that. It's 9:00 am. She's late and I'm horny. I decide to masturbate before she gets here. As soon as I get started, as you would guess, I hear the doorbell. I figure what the hell and answer the door naked and hard. Stephanie sees me with my erection and smiles. She walks in and, in what has become the norm, removes her coat and is naked. She gives me a peck on the cheek as she walks over to the stuff. She starts getting ready. Once the butt vibrator is in, she grabs the butterfly vibrator and asks me where she should go. I have the machine setup in my small dining area and direct her there. As she sits down, I tell her that we will be using the wrist and ankle cuffs today. She asks why. "Because you will masturbate if we don't. That's why I added the cuffs in the first place. Once you start getting frustrated by the machine, you won't be able to help youself and will want to masturbate. You'll understand better once we get started." That makes her smile as she gets into position. I kneel down and put the ankle cuffs on her while she puts the wrist cuffs on. When she is all hooked up, she lays down and puts the butterfly vibrator in place. I ask her if she wants me to give it a quick buzz so that she can make sure it is positioned correctly. She tells me that it's fine and that she's ready to get started. "How long do you want the session to go?" I ask her. "I don't know." "How about 15 to 25 minutes? That seems like a good place to start." She nods in agreement. I enter the parameters and start the program. Her arms and legs are gently pulled tight. I adjusted the pulleys so that her legs are pulled wider apart than mine are; I was worried she might knock the vibrator out of position if I didn't do that. Once the program has her tied tight, it pauses. "Are your arms and legs okay? They aren't pulled too tight are they?" "I'm fine" she tells me. I tell the program to start. I hear the vibrators and see her react to them. She is definitely enjoying the start of the program. It only takes a minute before she starts really reacting to the vibrators. I see that an edging cycle is about to start. As sit starts, I hear a loud moan from her. I quickly glance at the computer and see everything is looking good. I notice that this cycle will last a full four minutes. I look at her and see that the program is doing a great job of keeping her on the edge and of denying her orgasm. She continues to moan and starts to gyrate her hips. Her moans are growing in volume and are making me super horny. I resist the urge to masturbate. Her moans have become constant and she has started to grind her hips. She keeps this up until I hear the vibrators turn off at the end of the cycle. "Oh my god, you didn't tell me it would be like this" she exclaims. "What do you mean?" "That it would feel this good and be this frustrating. I need to cum more than I ever have before in my life. I can't believe how much I want to rub my pussy right now but I can't. " I smile and hear the vibrators start again. Almost immediately, she is moaning again and starting to move around. My cock is so hard from just watching her. I so need to cum but I'm planning to use the machine on myself once she leaves. That is, unless she offers me another alternative. I keep checking the computer and everything is working well. The program is doing what it is supposed to and she seems to be hanging on the edge of ograsm. Every so often, I get a bit worried the program is pushing her a bit too far but she hasn't cum yet so I don't make any changes. I hear the vibrators turn off as the cycle ends. "Oh my God. I so need to cum. Please, change the program and let me cum." I look at her. "It hasn't even been 10 minutes yet. You still have some time to go. And this is why you needed to have your arms tied up." "Please, oh my God, I need to cum." The vibrators start again. I steal a quick look at the computer and see that this will be a short 2 minute cycle. I notice that there is still 10 minutes left before the program will make her cum. I can't imagine how badly she is going to need to cum by then with how desperate she is this soon. She is constantly moaning and grinding. It looks like she is trying to get some pressure on her pussy but nothing is helping. Looking at her, I do think I need to adjust the pulleys to make her legs a tad wider next time just to make sure the vibrator doesn't shift. This cycle ends and she gives the neediest, sexiest, most frustrated moan I've ever heard. "Oh my God, please, make me cum. Please I need to cum. I'll do anything, just make me cum." I see that this will be a 45 second break before the vibrators start up again. "You'll be fine. Think how good the orgasm will be once you have it. The frustration makes the orgasm that much stronger. In fact, I'll bet that once you experience it, a normal orgasm won't feel as good." "Please, I can't take it" she says as the vibrators start up again. Almost immediately, she starts moaning. When I look at the computer screen, I see that it is already edging her. Somehow, she didn't cool down during the 45 second break. So I change the wait times to be 45 seconds to 90 seconds, 30 seconds longer than what they were. We continue like this for the next eight minutes. The increased wait time between cycles seems to help a bit as she's no longer right on the edge when the next cycle starts. But her moans and begging continue. The program has shut down the vibrators for the last time. I know that when they turn back on, they are going to make her cum though she doesn't know that. The vibrators start up, slower than normal. I made this change so that this part was more frustrating since I knew orgasm was coming but very slowly. Her reactions lead me to believe she notices the differences too. "Oh my God" she screams as the vibrators continue their slow, tortuous route to orgasm. To me, it seems to take forever; I can only imagine how frustrating it is for her. Before another minute has passed, she arches her back and let's out this incredibly sexy moan as her orgasm starts. It goes on forever; watching her cum is enough to make my cock drip pre-cum. After quite a while, I see her relax. When I check, I see that her orgasm lasted 53 seconds. That makes me jealous since I've never even hit 30 seconds. I know, men and women are different, but 53 seconds, jeez. I am jealous. Half a minute later, the program relaxes the restraints. It takes her a few minutes to regain her senses. She looks over and immediately notices my hard and wet cock. "Wow, was that all from watching me?" she asks me as she starts to disconnect herself. "Yes." "You weren't stroking at all, were you?" "No." "Would you like me to make you cum?" "Oh God yes" is the only reply I can manage. She comes over and starts to stroke my cock. It only takes a few strokes before I'm feeling my orgasm start. She stops the stroking, kneels down and takes my cock into her mouth. She is gently flicking her tongue on the underside of my cock while her moving her mouth along my cock. It only takes a few seconds of this before I cum. I shoot my load into her mouth. Too quickly, my orgasm subsides and she lets my cock, now getting soft, fall out of her mouth. Stephanie stands up, gives me a quick kiss on the cheek, whispers in my ear "That was the best orgasm I have ever had in my life. Thank you." She puts on her coat and is out the door before I can say anything. One day, I do have to find out why she runs out of here so quickly. But today, I'm content to just sit here and remember what just happened. At My Cabin Ch. 05 Stephanie and I have been falling into a routine. She comes by once or twice a week and gets edged by the machine. She usually follows that up by giving me a blow job. Although, once, when I was particularly horny, she put me in the machine and set the program to edge me for 75 - 90 minutes. That session lasted for 86 minutes and was the longest I've ever gone. I've made Stephanie go as long as 63 minutes. She came out of that session exhausted but happy. We'd never gotten into the machine together so I moved one of them back outside. I've been using the outdoor machine when I'm by myself. Stephanie always chooses to stay inside. I've starting developing some ideas on how I want to change our game. One idea of mine is particularly devious; I came up with it the day she put me in the machine for 90 minutes. The idea involves a portable version of the machine I'm working on. Using some cheap components, I have created a little computer to run the program. This computer can run on a pair of AA batteries for a week. It also includes a bluetooth connection so I can control it from my computer or my phone. I've attached this computer to a modified chastity belt. On the belt, I installed a clit vibrator. My idea is that the program will edge her for a day or more while she is walking around. My hope is that the belt will insure she can't work around things and cum. To help this goal, I did modify the belt by adding padding on either side of her pussy, mostly up around her clit and the vibrator. My hope is that I will be able to adjust the belt so that the padding pushes on her a little and will keep her from using anything on her clit while keeping the vibrator firmly in place. I've finally got the belt ready and am planning to use it when she shows up next. To keep her from getting suspicious, I will put her in the machine like normal. What she won't know is that I changed the program so that instead of making her cum, it will just stop and keep her bound. I will then remove the regular vibrator and add the belt. Her reaction should be interesting since she will be pretty horny from being edged for 30 minutes. Thinking about doing this never fails to get me horny. I end up in the machine six times over the next two days. Before I get in for a seventh, she shows up. Everything is progressing like normal. She gets naked and gets into the machine. I start the program and she starts enjoying. The 30 minutes hits and the machine stops. I see her tense in preparation for her orgasm. I notice her puzzled look when the machine doesn't start back up. She asks me if the program broke. I tell her no and get up. I get the belt and walk back towards her. She is telling me that she really needs to cum. I smile. After looking at her for another minute, I kneel down next to her and remove the vibrator. She moans and tells me how much she needs to cum. I see her clit sticking out and know that she is really horny. That makes me hard but makes what I'm about to do easier for me. I start to fit the belt onto her. She starts moving around but really can't stop me; her movements are pretty limited. "What are you doing?" she keeps asking me. Eventually, I get the belt on and adjust it. I lock it into place using a padlock. I go back to the computer and have the belt edge her. Immediately, I see her react to the vibrations. She starts moaning and humping so I'm pretty sure I have the belt well positioned. I let this edging session go for 10 minutes, which is longer single session than normal. When the time is up, I free her. She gets up and glares at me demanding that I remove the belt. "I won't. I love putting you in the machine. But I want to give you more. Plus, I want you to come here more. So now I've given you a reason to come back tomorrow. That is, if you want to cum." "You can't do this to me." she replies with a slight edge to her voice. "If you really don't like it, you can have someone cut the lock to get the belt off of you. But if you do that, don't come back here any more." As soon as I finish saying that, I have the belt edge her. As soon as it starts, she is moaning. She is also trying to reach her pussy with her fingers but can't. When the edging is over, I tell her more about how the belt works. "You can remove the butt plug for a maximum of 30 minutes at one time. If you remove it for longer, the vibrator will turn on and run at full speed until the batteries run out. It will continue to run even if you put the butt plug back in. My best estimate is that the vibrator will run for about 36 hours before the batteries die. So be ready if you try to trick the system. "To allow you to sleep, the vibrator won't run from 11:00 at night until 7:00 in the morning. And, by the way, the vibrator is set to edge you for 10 to 20 minutes every hour." "If you come back tomorrow, I'll put you in the machine and let you cum." "Please, you can't" she begs. She notices how hard this has made me so she comes over to me and starts to stroke my cock. When she gets me close, she starts edging me with her mouth. She continues for a while, not letting me cum. I tell the belt to edge her. She loses focus on my cock and starts concentrating on the sensations enveloping her pussy. Like our first session, she is giving this super sexy moan that has me desperate to cum. While the edging is still happening, I walk her to her coat, put it on her and send her on her way. She can barely walk and I'm loving it. I've never been so horny. As soon as she leaves, I put myself in the machine but keep the time short because I'm already so close to bursting. A couple of hours later, I hear a knock at the door. I open it and in walks Stephanie looking pitiful. "I can't take it. I just can't take it. There is no way I can last until tomorrow like this." I can't help but smile. "Please, you have to let me cum. This is driving me nuts. It keeps teasing me and I can't cum. I've tried but I can't. I can't get any sensation on my clit other than than that fucking vibrator." "Sorry but this isn't what I wanted. You need to come back tomorrow to cum." "Please. I'll let you fuck me. I'll let you do anything. I'll never make it through the night. I can't go back home like this." She sounded desperate. But her desperation didn't overpower my desire to leave the belt on her. "Please" she begs again. This time, she kneels in front of me and undoes my pants letting my cock out. I reach for my phone and trigger a 20 minute edging session for her. "If you can edge me until your edging session is done, I'll let you cum. But if you make me cum or let me get soft, the belt stays on until tomorrow." She immediately puts my cock in her mouth and starts to lick it. Almost just as immediately, I feel the effects of her edging session as she starts slowing down her efforts. I start to hump her face to bring her attention back to me. My goal is to cum in her mouth while she is lost in getting teased. Given the state she is in, I think this will be easy. It only takes me another few minutes and I'm shooting into her mouth. When she feels my orgasm start, she moans in frustration as she realizes what she let happen. Her moan continues, I believe from the frustration she is experiencing from the constant teasing. I check my phone and she still has a little less than 10 minutes of edging to go. I'm watching her and enjoying it immensely. In fact, by the time her 10 minutes is up, I'm hard again even though I've already had three orgasms today. I tell her she needs to go and come back tomorrow. But not before 10:00 I add. As soon as she leaves, I put myself in the machine for my fourth orgasm that day. The next morning, Stephanie is knocking on my door right at 10:00 am. I open the door and see that she didn't come alone. The woman with her is who was with her when she first ran across me. I also notice that Stephanie looks exhausted. The other woman introduces herself as Karen. "I'm Stephanie's partner" she tells me. I listen, stunned. I had never guessed that Stephanie had a partner or that Stephanie was gay. That explains why she never wanted to stay with me. Karen continues, "Stephanie has always had this fantasy about being teased and denied orgasm. When she saw you the first time, that was all she could talk about. She has told me all about her coming here and being put in your machine. I knew that she loved it and that she needed it. I was not crazy about it but she told me you two have not fucked so I believe her." "We haven't" I confirm. "I knew she was coming here yesterday while I was out. Then I get home and see her wearing this belt and moaning. It was so sexy. When the belt started to edge her after I got home, I couldn't believe it. Especially when it turned off without her cumming. She just sat there moaning. She then told me what had happened. So I told her I would come with her today because I want to see her finally cum." Stephanie is finally able to get some words out, "Please, let me cum". I look at Karen. She nods at me so I get Stephanie undressed and move her to the machine. I get her tied into it and remove the belt. Stephanie lets out this huge moan as the belt is pulled away from her pussy. Karen comes over to take a look; she makes a comment about how swollen her clit looks. I show Karen the vibrator I use on Stephanie when she is in the machine. I put it on. I hook up the butt plug and we are ready to go. I go over to the program and tell Karen how it works. I ask Karen if we should tease Stephanie some before letting her cum. Karen smiles at me; Stephanie starts to squirm saying, "No, no, no, no." "Just a little" Karen finally replies. "Also, I added a new feature. Because it has been so long since Stephanie has cum, I setup the program so that it can make her cum more than once. I'm thinking 3 orgasms is about right. What about you?" This evil little smile spreads across Karen's face when she says "Yes, I think that is about right." So I set the program to tease 5 to 15 minutes followed by 3 orgasms. As soon as it starts, Stephanie is bucking and moaning. Karen starts telling me about Stephanie as we watch her get teased. "She has always wanted to be teased and denied orgasm. I've tried to do it but I never made it longer than 10 minutes or so. That's why she kept coming here. She loved what your machine did that I couldn't do." "But, what you did to her yesterday though was one of her fantasies. She's always told me about wanting to be denied orgasm for an extended time. In fact, she is probably going to want to do this again. Only I think the next sesion needs to be a bit longer; maybe four days". I look at the computer and see that this is the last pause; it will make her cum as soon as it starts. I hear the vibrator start again and look over at Stephanie. Karen looks over when she hears Stephanie start moaning again. It only takes seconds for Stephanie to cum. Her orgasm goes on forever. Now that I think about it, that probably has something to do with the vibrators not turning off. They aren't turning off because I set it up to giver her no break between orgasms. So the vibrators won't turn off until she cums twice more. It doesn't take long for her to cum again. It is not as intense or as long as her first but she still enjoys it. And, like last time, she keeps cumming while the vibrator continue to torture her now super sensitive pussy. She starts thrashing against her bonds like she never has before. She must be getting pushed beyond anything she has experienced before in the machine. This keeps up for a few minutes and then she cums again. This orgasm is unlike any she's had before in the machine. She is screaming and thrashing around; I'm worried she is going to break something or hurt herself. Before too long, I hear the vibrators turn off and Stephanie collapses in her bonds. The ties let up and she is too tired to move. I head over, disconnect her and help her up. I loved the moan I got when I removed the vibrator. Karen comes over to help her stand up. She gets up, gets her coat on and they leave. I'm left horny but satisfied. At My Cabin Ch. 06 Seeing Stephanie in that belt and unable to cum has got me obsessing. I need to find a way to do that to myself. I don't want a chastity cage; I want to be hard and teased and denied for longer than I can stay in my machine. I'm still trying to work out the details. I already have a portable version of my machine; that much I know. But I'm struggling in working through how to keep me denied while I'm getting teased. I've tried cock tubes but I found they they either limited sensation too much or they don't prevent me from stroking. Recently though, I had a different idea. Instead of restricting access to my cock, I'm thinking I can bind my hands so that I can't reach my cock. This will rule out multi-day denial (not to be gross, but I do need to take the butt plug out for my daily constitutional) but it would let me go a full day. I decided to give this a try. I got a collar to put around my neck, two cuffs for my hands, some chain and some locks. I played with the chains and have them so that my hands can't get closer than a few inches to my cock. I'm thinking this will work. So now I'm looking at the last two problems. First, I need to do something with the key so that I can't just unlock myself. Second, I need to do something with my computer, otherwise I will just be able to run the program and make myself cum. The key has a simple solution. From looking at self-bondage web sites, I saw about freezing the key in ice or mailing the key to myself. But then I stumbled across something about a safe with a time lock. I figured I could use the computer to set the time on the lock. And I can have it unlock the safe when it lets me cum. But that leaves the computer. What I decided to do is to put the program on an external hard drive that I will lock in the safe with the key. That way, once the safe opens, I can get at everything. I order what I need to execute this plan. I get everything I need, assemble and test it. I test setting the time lock on the safe a lot because I need to be sure I won't be locked out. All this work and thinking about the teasing I'm going to get is making me horny. I'm cumming three or four times a day and still thinking about cumming more. At this point, my plan is to do this to myself on Saturday. I hear from Stephanie on Thursday. She tells me that she can't stop thinking about the denial the belt put her through. And that Karen finally told her it was okay to do it again. So she is here to get teased. She gets naked and I put her in the machine for 30 minutes to get her going. Like last time, I put the belt on her and test it before letting her free. What I don't tell her is that I changed the timing. It will now edge her for 15 to 30 minutes out of every hour. I do tell her that it will not run between 11 pm and 7 am like last time. I also remind her that she can remove the butt plug for no more than 30 minutes before the vibrator will kick in. I do tell her to stop by tomorrow for batteries even if she isn't ready to get the belt off. She looks at me puzzled but she is so horny already that I can see it is hard to think. By the time she is dressed and ready to go, she can barely walk. I finish my belt on Friday. I'm trying not to cum so that I'm super horny for my Saturday session. It is getting difficult to refrain, especially when I start thinking about what Stephanie is going through right now. Stephanie shows up with Karen early that evening. Stephanie looks horny and exhausted, Karen looks rather pleased. I can't help but smile in thinking that I will be going through tomorrow what Stephanie is going through today. Karen reminds me that I told Stephanie to come today for new batteries. I tell them that it is for the control computer and I can get to that without removing the belt. As soon as she hears that, Stephanie starts begging to cum. Before I can say anything, Karen jumps in, "Sorry honey, but no. You told me you wanted to go longer than last time. So that means tomorrow night at the earliest." I can't tell if Stephanie is crying or moaning after hearing this. I put in the new batteries. I check on my computer and everything seems to be working. Stephanie looks at me and asks why she is having a tougher go of it this time. I tell her how I extended the time it edges her. Hearing this, Karen smiles and Stephanie moans. "That's not fair" she yells. Karen gives Stephanie a look. They then head to the door and leave. I'm now hard as a rock and really need to cum. I'm able to control myself until bedtime. It is hard to get to sleep because I'm horny, but I manage. I awake a bit earlier than I had planned with a raging hard-on. I get ready for the day by staying naked. After breakfast, I get all of my equipment on except for the collar. I go and setup the program. I set it to edge me for 10 - 20 minutes out of every 30. I am worried this might be a bit much but that thought also excites me. I also tell it to let me cum and unlock the safe in 8 to 10 hours. I click the button to activate it and feel an edging session start. I remove the external drive and get it into the safe. It is weird doing this while getting teased but it is also weirdly enjoyable. I put the collar around my neck and put the cuffs on my wrists. I check the chain lengths and confirm I can't touch my cock; the chains are about 4 inches too short. Perfect. I make sure the key is in the safe. It is. I insert the locks and snap them closed. I take a deep breath and lock the box. There is no turning back now. It feels like the teasing is intensifying though I know it is just my situation making me feel that way. I feel my first edging session begin. OMG, it is intense. I'm already thinking how stupid this was, I don't know how I will manage through more than 8 hours of this. The first two or three edging session are enjoyable. I'm relaxing between then and enjoying the situation more than I thought I would. I now realize that using the machine has me more used to this extended edging than I thought so I'm happy with the timings I set. When the next edging session ends I notice that I can't relax as much because I need to cum so badly. I'm staying hard for an extended period after the sessions end. And, omg, I've never need to cum so bad in my life. I need it more than when I was in the machine for 90 minutes. But I can't do anything about it but take it. When three hours have passed, I'm going nuts and trying everything to make myself cum. I've tried laying face down on my bed and rubbing my cock on the mattress. That didn't work because the vibrator and sleeve on my cock prevented me from getting enough rubbing. In fact, that sleeve and vibrator have prevented me from rubbing out an orgasm on everything I've tried. I'm no longer going soft between sessions. In fact, I'm near orgasm almost as soon as the sessions start. I glance at the clock and realize I still have at least four hours of this left. I put some porn on on my computer and enjoy watching it while getting edged. I've never done that before and it is intense. The teasing is making me enjoy the porn more. More than 7 hours have passed. I'm hard and near orgasm all the time. As my next session starts, I hear a knock at the door. I'm so horny that I don't think I could even walk to the door so I ignore it. But whoever it is won't go away. They keep knocking. I then hear Karen yelling "Hello, are you home?". My session is still going and I'm so close to orgasm that I try and ignore her. The interesting thing is that the knocking is distracting me but that is making the vibrators work harder. Two minutes ago and I believe this much vibration should have made me cum. But I can't because of the knocking and yelling. They finally leave and I'm in misery. I need an orgasm more than I ever have in my life. Luckily this feels like a shorter session and ends before too much longer. I'm near the end of my eighth hour. I've lost count of how many times I've been edged. I'm so horny. I think most sensations are almost enough to make me cum. When I walk, the breeze on my cock almost makes me cum. The air blowing out of the air conditioner vent is almost enough But nothing is working. I've resigned myself to not cumming until my time is up. Every time the vibrator starts, I feel myself trying to cum; hoping to cum. That is making the sessions more intense than earlier. And more frustrating since I know I might be allowed to cum now. Then I hear the knocking again. I have five minutes or so until my next session so I figure I'll get it. I peep through the window and see Stephanie and Karen. I let them in as I'm betting Stephanie wants to cum too. Seeing her in the window makes me realize that I won't be able to take her belt off until I cum; the keys for her belt are with the keys for my cuffs in the safe. And, I can't update her program to have the belt make her cum because the hard drive is in my safe. My cock starts to twitch at these thoughts. When they come in, I notice that Stephanie looks tired. They notice my condition and ask me what I'm doing. I explain as best as I can. While I'm explaining, my next session starts. I start stuttering and am having a hard time finishing my sentences. Stephanie looks at me and asks "Can you please get this thing off of me? I've been teased so much and I need to cum. I can't take much more". I'm trying to concentrate on what she is saying but I keep getting distracted. When she finishes, I explain the problem. "You see ... the key for your bbbbelt is in the safe with .... mmmmmm ... the key to my cuffs." "I can't get you out until ... mmmmmmm ... I cum and the safe opens". Stephanie moans in frustration at this news. "How much longer" she asks me. "Less than an ... Oh my God ... hour". I hear Stephanie's vibrators start. Seeing her writhe around and listening to her moan makes me hornier; I feel my vibrators almost stop so that I don't cum. Unfortunately, my session ends when Stephanie's gets into gear. Karen is staring at me. I think she loves to look at my cock like this. It is hard, larger than normal, and purple. I'm willing to bet my balls are pulled up pretty tight. I smile back at her. Karen asks, "why did your session seem so short?". Since my session is over and I've calmed down just a little, I'm able to talk somewhat normally. "Because, my sessions are only 10 to 20 minutes. But that is out of every 30 minutes, not every hour like Stephanies." Suddenly Stephanie starts moaning even louder. She is thrusting her hips now while the vibrators keep going. Watching her is keeping me near orgasm. I still feel like two strokes and I would cum. Suddenly, my vibrators start up again. I'm pretty sure it isn't yet time for the next session; I'm hoping the vibrators will make me cum now. The vibrations start out slow, slower than normal, though in my condition that could be what they need to do so that I don't cum. I'm staring at Stephanie and enjoying the sensation while watching her get teased mercilessly. I feel my vibrators speed up and my orgasm builds. I'm moaning louder than Stephanie now. My vibrators keep speeding up until I start to cum. My cum shoots out of my cock further than ever before. I'm writhing all over and I keep cumming. After what feels like forever, the vibrators slow down and my orgasm ends. Pretty quickly, my vibrators turn off. I'm not moving when I hear the click that means the safe is open. So everything worked correctly. I unlock my hands then free my cock and remove the butt plug. I stay naked. When I see the hard drive, I realize I can change her settings so that the belt will make her cum. She won't be expecting it because she is expecting to get into the machine. I grab the drive and head to my computer. I start up the program and see that she has 8 minutes left in her session. I make a quick change so that her session will end as normal but 30 seconds later, the vibes will start again and she will cum. I tell them that I will remove the belt when the session is done. I sit back and watch Stephanie get teased. Her nipples are hard, her hips are grinding against the sofa, she's moaning non-stop and Karen is staring at her with lust in her eyes. I suspect Karen wants to masturbate but won't because I'm here. My cock is getting hard again even after the day it had. I ignore it and enjoy watching Stephanie. When the sessions is over and her vibrators stop, I'm super hard again. It is taking a lot of willpower not to masturbate but I manage to keep my hands off my cock A few seconds later, Stephanie looks at me. "It's stopped. Can you please get this thing off of me now?" she asks desperately. "Ok, let me get the machine ready." I say as I get up. As I start walking towards the machine, I hear Stephanie moan as the vibrators start up again. "What did you ... do? Please, it's been 3 ... ddddays. " she begs as the vibrators start working their magic again. She starts to react differently. She is grinding her hips more than before and her moaning gets quieter though it looks like she is screaming. Suddenly, she starts to cum. She lets out this hot, sexy wail as she grabs the sofa and arches her hips. She stays like this for a full minute. Karen is transfixed as am I and my cock. Just as suddenly as it start, her orgasm passes. She relaxes her body and sits back down on the sofa. She looks like she is asleep when Karen goes over, sits down next to her and gives her a kiss. I give her a couple of minutes to recover then I walk over and ask her if she is ready for the belt to come off. "Yes" is all she says. I lay her down on the sofa and I unlock the belt. I remove it very gently. She moans when it is removed from her pussy. Her pussy is engorged and very red; much more so than previous times. She reaches around, removes the butt plug and hands it to me. She notices my erection and smiles at me. Karen then gets her up and puts her coat back on her. They leave without saying much to me. I'm still hard so I masturbate. Then I head to bed because I'm exhausted. At My Cabin Ch. 07 It has been a week since Stephanie was in her belt and I in mine. I haven't worn it since thought i have used the regular machine quite a bit. And, it's getting cold out so all of this has happened indoors. And, by myself. I've been contemplating wearing the belt again; this time for 8 - 10 hours. I'm thinking about that again when I hear a knock. I'm surprised to see Stephanie, especially without Karen. I open the door and give Stephanie a simple "Hi". "Can I come in?" "Of course" as I wave her in. She takes a seat, and looks at me. Karen has told a couple we know about you and your teasing machines. They might be interested in buying versions for themselves. Are you interested?" "I don't know. It seems like a lot of work for people I don't know." "They have said they'll pay. And, I think they have money." I thought about it but I still wasn't sure. "If you started selling them, I bet you could make more money making these machines than by what you do now. They are unique and a lot of people would love them." "I never thought about that. Maybe I am interested." She smiles. "We were thinking that you and I should demo them. I'll wear the belt, you will demo the machine. That way, they will really understand what the machines do." I look at her surprised. "Me? In the machine? With a couple in my house?" "Yes. It's your machine and I think you need to show it. Plus, you look incredible when you are being teased by it. And, we thought you'd be okay with that since the first time we saw you, you were outside in full public view." I didn't know how to reply so I stood their tongue tied and probably looking a bit pathetic. "Could we do this tonight? They are available and anxious. I could come over about 5:00, you could get me into the belt and get the machine ready for you. Karen, Sam and Hank would be here around 6:00?" "Sam and Hank? Am I demoing this for a only guys?" "No, silly, Sam is short for Samantha. And I think you'll like how she looks" she says, smiling. Before I thought about this too much, I said "Ok". She kissed me on the cheek and left. A few minutes later I started to realize what I agreed to. I had put myself in positions to get caught before but I had never performed in front of a group before. But that's what was expected of me tonight. That thought was making me hard. So I figured I'd go through with it and see what happened. 5:00 took forever to come. I held back and didn't cum all day. Since I was hard most of the day, this took a lot of self control. I heard the knock and Stephanie let herself in. She took off her coat and she looked stunning. She was wearing a tight t-shirt, no bra, and a skirt that came to mid-thigh. "I didn't want to have to walk around naked all night. So I wore something that I could wear with the belt." "But when I get into the machine, I don't want to be the only one naked." "Oh, don't worry, Before you get into the machine, I'll get naked with you. I might get dressed when you are done or I might stay naked until I cum. I just don't want to be naked when everyone else gets here." I showed her everything was ready. "I've made a few changes to the belt and to the program. You won't notice most of those changes. But I am wondering how long we should do this for? I was thinking 60 - 90 minutes for me but how long for you?" "I don't know, I hadn't really thought about it." "How about 3 - 4 hours? That seems long enough, especially if we start the belt before everyone else gets here." "K" I get busy setting up the program while Stephanie gets herself ready. As she's putting in her butt plug, she asks me about the changes I made. "Let me remember. The one you might notice is that I've tweaked the settings so that it should bring us closer to orgasm than before." "Second, the timing starts with you are ready to cum instead of when the vibrators start. So if it's set to edge you 20 minutes out of every 30 and you take 10 minutes to be ready to cum, the next 30 minute session will start right away. So the breaks be shorter early on and longer after you've been edged for a while." There are a few more changes but I decide not to mention them right now. "Are these changes just for me?" Steph asks. "No. These changes will affect us both." I'm done setting up the program so I help Stephanie finish getting the belt on. We do a quick test to make sure it is positioned correctly. She puts her skirt back on and we wait. I turn on the tv and put on a news program. I think we are both antsy as neither of us is watching the program. I'm really horny and sitting with an erection. Knowing Steph has the belt on and is waiting just adds to my frustration. "Do you want me to turn the belt on now?" "I'd like to wait until everyone is here. Though I can't wait for it to start." So we both continue to wait for the others to show. 6:00 comes and goes. Finally, about 10 minutes late, Karen shows up with Sam and Hank. Sam looks about 40, he looks a few years older. Hank is an okay looking guy from my limited perspective. Sam looks great; she is someone I'd love to see naked. I get a bit more excited when I realize that I might get to see her. "Welcome" is all I can think of to say. I don't wait for an invitation and show them the machine. Hank starts asking me all sorts of questions about it; I tell him a lot though I leave out a few details to protect my interests. He might realize this because he starts asking more detailed questions. I finally have to say, "Why don't we just show you." I call Steph over and have her show them her belt. Sam is examining it pretty closely. She asks Steph, "You can't touch your pussy with this belt on, can you?" Steph just shakes her head no. She goes back to the sofa and takes a sit. Karen moves next to her while Sam and Hank sit in a love seat across the room from them. I move towards my computer to get things started. "First, I will start Steph's belt." Steph let's a little moan escape her lips when the vibrators start. That grabs everyones attention; we are all staring at her as the vibrators keep bringing her closer and closer to orgasm. I look at Sam and Hank but I'm not sure if Hank is enjoying the show. He's watching but it doesn't look like he's hard. Sam, though, looks like she might be getting horny. It's been five minutes and the machine starts edging her. It's then that I realize she was really horny before we started, her first session usually takes closer to fifteen minutes. As the edging starts, I start telling Hank and Sam how it works, "The belt has two vibrators, one on her clit and one in her butt. They work in concert to make her cum but as she gets close to cumming, they slow down so that she can't cum. They will stop if they have to and will start up again as soon as she has moved away from orgasm a little bit." "It will edge her for 20 out of every 30 minutes. When the 20 minutes are over, the vibrators will shut down until it is time to start again. After three to four hours of this, the vibrators will give her an orgasm." "What's the longest she's gone?" Sam asks. "A little more more than 2 days but with it running much less time; just 15 - 30 minutes every hour. And, it turned off at night so she could sleep." "Oh shit, 2 days? Being constantly aroused? How did she handle that?" Karen answers, "It was tough. By the end of the first day she was a mess. By the end of the second day, she was barely able to function and needed to cum more than I thought possible. I don't think she would have made a third full day. I did enjoy it though because the one release she had was making me cum." Karen starts blushing. "Can I see the belt again?" Sam asks Stephanie. Stephanie starts removing her skirt but keeps stopping as she gets edged. She decides to stand up to remove it and she is a sight. Her legs are shaking, her hips are humping and she's wiggling to remove her skirt. It takes a good 30 seconds for her to get her skirt to her knees. It is one of the hottest things I have ever seen. Steph sits back down. Karen helps her remove the skirt from her feet. Sam heads on over to look at the belt again. I tell her about the belt, that it is a modified chastity belt. "How does it keep her from cumming?" "The vibrator in her butt is also a pressure sensor. The control module senses the readings and determines how close she is to cumming. It uses that information to control the vibrators. The interesting effect is that if you try not to squeeze, the vibrators get you closer and closer. But, eventually, you get close enough that you squeeze hard making the vibrators stop. So fighting the orgasm can intensify the effect." Stephanie must be in-between sessions now. Sam notices her calming down and asks, "Did you cum?" "No. It's just giving me a break." Steph removes her shirt and is now naked except for the belt. She looks at me and says "Your turn". Sam gets a puzzled look on her face. So I ask her if she knew that this works on both men and women. "No, I really had no clue. I assumed it was just for women." "It started as a machine just for me; the machine I showed you when you first got here. Karen and Steph caught me in it one day. Steph then wanted to experience it for herself so I adapted it for women. I then created a belt version for her and adapted it for myself though the version for me doesn't allow me to wear it for multiple days." I tell everybody I'll be right back and head to my bedroom. I undress, and insert the butt plug. I'm hard and thinking about putting on a robe for my walk back in. I decide to stay nude since I need to be nude to get into the machine. I walk back into the living room towards my machine. I'm a bit nervous as I've never been naked in front of so many people before. And, I've never been naked and aroused in front of a guy before. But I power through it and think about Sam naked. I notice that Sam is staring at my erect cock as I'm looking at her. I glance over at Steph before getting into the machine; I can tell that she is getting teased again. Seeing her naked and getting edged gives me the courage to get into the machine. I walk over to my computer and start the program. I tell the program to start in five minutes, giving me a chance to get into the machine. I lock the computer but I have a screen saver that shows what's going with the program. I take a seat by the machine and start getting ready. I put the vibrator on my cock, and then put on the ankle and wrist restraints. I lay down and explain the reason for the restraints. I then let them know that the program will start by pulling my restraints taught. I wait a few seconds and I feel them pulling. I feel the vibrators start. "The vibrators will edge me for three to five minutes at a time. When the time is up, they shut down for 15 to 60 seconds and it begins again. This is pretty much the same thing Steph is going through though the sessions are quicker." Another minute or so, and I'm ready to cum. I'm getting edged when I notice Sam watching me. After a minute of me trying to cum, Sam is over taking a very close look at my cock. "Wow, that is a swollen cock." Before I know what's going on, she reaches over and starts feeling my balls. I almost cum but the program quickly adjusted. My cock starts to bob around and almost pulse because I am oh so close to cumming. I croak "stop" because she is driving me nuts. She is enjoying watching my cock move around so she keeps on feeling my balls. I'm enjoying what she is doing so much but I so want her to stop because it is making me feel my lack of orgasm even more. She smiles. "Wow, you really are close." But she doesn't stop. The vibrators turn off and I get to my first break. She keeps on feeling my balls and she moves a finger to my cock. Her touch makes me moan and thrust my hips. She keeps it up until the vibrators start up again. They are instantly edging me; there is no build up. She keeps playing with my cock and balls like this for the next fifteen minutes or so. I've never felt the machine as intensely as I am with Sam's help. Finally, she stops playing with my cock and balls. I'm so horny though that I'm not coming off the edge when the vibrators stop. My next session starts and start right into edging me because I'm instantly ready to cum. Sam comes back and is next to me again but now she is topless. She has great looking tits and big nipples like I love. She leans over and pushes a nipple into my mouth. I start sucking on it like I've never sucked on a nipple before. As I get edged, I moan into her nipple. That gets Sam moaning. Sam lets me suck on her nipples for a while. I don't know how I'm not cumming; I've never been so close for so long. I'm so enjoying sucking on her nipples that I didn't notice that she started to feel my balls again. This This keeps up for a while. I'm constantly ready to cum, and I can't quite get there. I'm enjoying this excruciating tease more than I have in a long time. Stephanie, who I've almost forgotten about, is on the sofa. Watching what is being done to me seems to be affecting her as she is moaning non-stop. It's close to to an hour since I've gotten into the machine when things change. Sam, starts to remove the vibrator from my cock. I ask her what she is doing, but she just carries on. When she has the vibrator off, she looks closely at my swollen and stiff member. She's stroking it very lightly and very slowly. She asks me if I'd like to cum. "Yes, please." Sam smiles and removes her hand from my cock. She sits down on my chest facing towards my cock. Hank walks over and puts a bag down next to her. She pulls something out of the bag and is blocking my view of what she is doing. I feel something really cold against my cock and balls. I immediately lose my erection even though I'm desperate to cum. Once I'm fully soft, I feel a ring being placed around my cock and balls. I'm still not sure what she's doing but I don't like it. I start twisting around and fighting so that she finish doing whatever it is she is doing. In response, she rests more of her more of her weight on me, making it much harder for me to move around. I feel another item being put on my cock. I also feel something going into my urethra. I hear a click and see her grab a tool. When she gets up, I see my cock and balls are locked in a chastity cage. My cock is held in place by the thing that's in my urethra. And, it's way too small for me to get erect much less cum. The whole situation and the fact that I'm still super horny has my cock trying to get hard. I quickly fill the device and feel pressure as the cage prevents me from getting hard. I let out a frustrated moan that makes Sam smile. A few minutes later, the machine releases me. I quickly remove myself from it and get up. I look at Sam and demand she removes the cock cage they put on me. Hank is the one to reply. "Why should we do that? We heard what you did to Stephanie. How is this any different?" I was not expecting that; it hadn't even occurred to me. In a weird way, they might be right. But my need to cum out-weighs everything else. "She was getting edged the whole time. And she loved it. Me, I can't even get hard right now much less edge myself." Sam replies this time, "Don't worry, you'll cum again. It is just up to me as to when. Just like it was up to you when you put the belt on Stephanie the first time." I sigh. All I can think of is how horny I am. My cock is filling the cage with its need to get hard. And, hearing and seeing Steph getting edged is increasing my frustration. From being edged so much, I thought I knew what frustration was. I realize I didn't really understand frustration until now. My brain starts working a bit and I get an idea. I go over by Steph and ask her "Did you know they were going to do this?". She doesn't reply so I ask again, this time touching her knee to get her attention. "Yes" is all she says. I stare at her trying to comprehend her response. Two ways out of this dilemma come to me. First, I can change the settings on Steph's belt so that the vibrators start running at full speed and don't stop. Or, I can make the belt edge her with no breaks. Either of these should help me make my case to get this cage off. Still not sure which way I'll go, I walk over towards my computer. Hank asks me what I'm doing but I ignore him. I sit down and bring up the control program for Steph's belt. I change the settings to endless edging and lock the computer. All of the sudden, Hank is behind me and asks me what I'm doing. "Sorry Steph, but your belt will now edge you continuously, no breaks. Not even the mini ones that it gave you during the edging sessions. And, it will run all night." Stephanie reacts to my message by groaning in frustration as she continues to get edged. Karen looks shocked. I look at Karen and say, "When I cum, she'll cum." Hank says "This doesn't change a thing." I get mad. "Let's see if it doesn't. I don't think she can take another hour with no breaks much less days. And the batteries in there should be good for another 3 or 4 days. Image what she'll be like after 3 days of constant edging." Hank doesn't change his tune, "It still doesn't change anything." I'm not sure if he thinks I am bluffing or if he just doesn't care. All I think about is wanting this cage off. And, I don't feel too bad for Steph because she knew this was going to happen. I call Hank's bluff, with a simple, "Ok." The one thing that could stop this is that the key to Steph's belt is in my desk. She might remember that at some point so I definitely need to lock it away. Karen comes over to me and whispers, "Please, let her go. She can't take it." "As soon as this cage is off, I'll make her cum and remove the belt." Karen must sense that there is no point in pushing it so she goes and sits next to Steph. Steph leans into Karen and Karen tries to comfort her while the edging continues. The next thing I know, a naked Sam is standing next to me. She's shoving her shaved pussy towards me making me groan in frustration again. "I need to cum" she says as she thrusts her pussy towards me again. I shake my head no but she spreads her legs and starts rubbing her pussy. I'm so horny I can't help it, I lean over and start licking her pussy. She starts moaning and riding my face. I trace patterns across her clit. My desperation for orgasm is making me desperate to see her cum. It doesn't take long before she grabs my head, pushes her pussy into my face and starts to cum. And cum she does. She holds my head and pulls me into her pussy; riding my tongue. And she's noisy. She lets go of my head and I lean back. My balls feel swollen. I look over at Steph and see that she and Karen were watching. She looks like she needs an orgasm worse than ever; the no is definitely taking its toll. Sam goes over and collapses next to Hank. I open the drawer to grab a tissue to wipe my face. I grab one and the key to Steph's belt. I hide the key in the tissue as best as I can while I wipe my face. I get up and walk towards my bedroom. I go to a small safe I have and quickly open it and get the key in there. As I'm closing the safe, Hank appears at the door. He asks me what I was doing. I don't reply. It is a bit weird considering that I'm naked and it's only the two of us in here. So I get up and walk into my bathroom, ignoring Hank. I lock the door behind me. I feel that dull ache in my balls that I remember from high school; I have a case of blue balls. I wash my hands and face and remove the butt plug then I examine the cage. It has strange screws holding it in place; they have three little holes instead of a standard screw head. I might be able to get them out but it will be difficult. And, the device looks well made. I can't even try and pop my cock out because the urethral tube makes that impossible. At My Cabin Ch. 07 I have to pee and don't know how that will work with this cage on. So I just go ahead. The urethral tube is hollow, so I pee with no issue though cleaning up is a bit difficult. I finish up in the bathroom and head into the other room. Sam and Hank are dressed and walking out the door. "Wait, what about this cage you've put on me" I scream. "Don't worry, I'll be back tomorrow or the next day" Sam tells me as Hank pulls her out the door. The door closes behind them. I stand there staring at the door, unable to believe my situation. Karen comes over and gets my attention. "You have to do something for Steph, you can't leave her like this." I look over and realize Karen is right; Steph is being driven nuts by the constant edging. She looks like she is in pain. I can't leave her like that so I I walk over to my computer and tell the program to immediately let her cum. It doesn't take five seconds for her orgasm to start. She is cumming hard, her body is tense, her mouth is open but she's not making any sound. After about 10 seconds of this, she starts to shake and moan. That goes on for another 20 seconds, then she collapses back onto the sofa. Karen asks me to remove the belt. I tell her that I won't, not until this cock cage is removed. I assure her that the belt is turned off won't start again unless I do it on purpose. She gives me a nasty look. I glare back and she let's it go. She moves over by Steph, helps her up and into her coat and they leave. I'm now alone, horny and unable to cum. I clean up my place a bit and head to bed. At My Cabin - The Next Year ---- I didn't like where I took the previous series in the last part. So I decided to start a new series, that takes place about a year later. ---- A few weeks after I left the cabin last year, I met Sara. We've been going out ever since, about 8 months now. My relationship with her is serious; she lives in my apartment with me and we've been talking a little bit about marriage. I have told Sara about my fantasies around being teased and edged. I haven't yet told her about my machine or about what happened at the cabin though she does know a little bit about Stephanie. Sara has edged me quite a few times. She can't go anywhere near what my machine did but it is great none the less. Being edged by a hand and a mouth is fantastic even if it doesn't last as long as I would like. I've tried teasing her a few times but she hasn't seemed that into it. This is probably the only place where we have different tastes sexually. A week ago, Sara was laid off from her job as a CPA. She's pretty upset so I asked if she'd like to get away by going to my cabin for a few weeks. I told her that I can work from there and it might be good to get away for a while. She seemed okay with the idea so I started getting everything ready for us to leave. I figured now was a good time to show her my machine. I was a little worried since I had kept it from her for so long but was hoping that would be okay. I also thought the best way to show it was to demo it. The next day, she left for the house for a few hours. I used that time, got the machine out of storage and set it up on the bed. It was working great. A few minutes before I expected her home, I got undressed, and got myself ready for the machine. I had everything in place except for the vibrator on my cock; I left that off for now. I put on my robe and grabbed my computer. I set the computer up next to the bed. I started up the program and set it to edge me for 30 minutes. That seemed like enough time to show what the machine did without being excessive. It also seemed like a good length of time considering I hadn't been teased anywhere near that long in the last 8 months. Anticipating the teasing had me excited. I left the bedroom and was walking around with my cock sticking out of the robe. I started to clean up a bit to pass the time. That experience was weird as I had never cleaned up with a butt plug in place before. It did make me keep my erection the whole time I was waiting. A few minutes later I heard the car door as she got home. I went into the bedroom, removed my robe, put the vibrator on my cock and attached myself to the machine. She walked into the apartment and immediately asked me to help with the groceries. I finished attaching myself to the machine a few seconds before she found me. She froze in the doorway and stared at me. After 30 seconds or so, I asked "Do you like my edging machine?" She didn't say as she started to walk towards the bed. Her expression changed; she was looking a little puzzled, and a little mad. So I figured I better explain. "Last summer, I was bored and lonely at my cabin. I was also horny. So I designed and built this machine to edge me. It's controlled by the computer and it will edge me for as long as I want. Right now, it's for 30 minutes once I tell it to start." "You're tied up?" "Yes, I did that to me. It's not tight right now. If I don't do it, I will masturbate before the session has finished. The ropes will tighten once it starts to keep me from being able to cum until the time is up." "How much do you do this?" "I haven't done this at all since we started going out. But I did use it a lot at my cabin last year." "What's a lot?" "I was in the machine to cum about 3 to 4 times per week." "Wow. What's the longest you let it tease you?" "About 90 minutes in this machine. I also have a more portable version that teased me for almost a full day. It's excruciating and frustrating to need to cum so bad but to not be able to. I wanted to show you the machine because I'm hoping we can both use them at the cabin." "Me? In that?" "Yes, I'm hoping you will try it. RIght now, I just wanted to show you what it does." "I'm not getting into one of those that SHE used" she said while giving me a rather nasty look. "No, that's not it. I have more than enough parts to build you a new one. The only thing that will be reused is the frame and the rope. But the cuffs, the vibrators and everything else will be new." "Vibrators? I only see one." "There's one in my ass too. It's also a sensor and is what allows the machine to know when I'm about to cum." "Oh. I don't know if I like that." "It's not as bad as it sounds" I tell her. "Did you build this for Stephanie?" "No. I built it for me. She caught me and asked me to make one for her. But we never experienced it together which is what I want to do with you." Sara is starting to get upset. I didn't expect that and I'm starting to go soft. I better either get this started or get out of the machine. But I don't want to just start it, so I ask her if I should. She doesn't reply so I go for it and start the machine. Immediately, my arms and legs are pulled taut and the vibrators start. My cock quickly gets fully hard again. Sara reaches over and feels my cock with the vibrator. "That is pretty strong. You'll be cumming in no time." I don't reply. I'm feeling good as the vibrator does its thing. It's more intense than I remember. Sara moves her hand to my balls and starts to massage them. This goes on for a couple of minutes. "You are already close." She's right, my orgasm starting to build. The vibrators keep going and I keep getting closer to cumming. And then, as I'm about ready to cum, the vibrators slow down a lot and the edging starts. "It's doing something different now, ins't it?" I shake my head yes because I can't talk. I can and do moan and start to struggle against my bonds a little. It's been a long time since I've been teased like this so it doesn't take long before I start to feel the full effects of the teasing and let out a loud moan as I'm kept on the edge. Sara lets go of my balls but continues to watch me as I struggle more and more. After what feels like an eternity, the vibrators turn off for my first, brief respite. "What do you think?" I ask her. "That's it? You didn't cum." "I will. It's programmed to give me a short break every few minutes." "How much longer will this go on?" "Look at the computer, it will tell you". "22 minutes left. In that case, let me go and put the groceries away. I don't want the ice cream to melt" she says as she walks out of the room. The vibrators start back up and it doesn't take long before I'm ready to cum again. When Sara comes back, she sees an aroused and frustrated mess writhing on the bed. The teasing is getting to me more quickly than I thought it would; I'm glad I only set it to 30 minutes. When the next shut-down comes, I tell Sara to look at the monitor and see how much longer I have in the machine. "12 minutes left" she tells me. When the next session begins, Sara keeps updating me on how much time is left. I find that it escalates my frustration a little since I know I'm not going to cum yet. When the counter is down to about 3 minutes left, she almost gives me a countdown to my orgasm. When it gets to zero, Sara watches as the vibrators bring me closer and closer until I cum. And do I cum. I shoot all over myself and the bed. The machine releases me as I'm recovering. I start disconnecting myself when Sara says, "You are going to clean this up, right?" "Yes. But what did you think of the machine?" "It was okay. Why?" "Will you try it?" "I don't know if I want to be teased like that. I did enjoy watching you though." With that, she heads into the other room and I clean everything up. At My Cabin - The Next Year Ch. 02 Sara was acting like nothing happened. She didn't bring up the machine. I didn't either. I was worried that she was upset but, other than not saying anything about it, she wasn't acting upset. In fact, she acted totally normal that evening, talking to me and kissing me. We had dinner together and then watched some tv. When we were ready for bed, Sara headed to the bedroom while I spent a few minutes cleaning up. I headed towards our bedroom intending to ask her what she though of my machine. Instead, I find Sara already asleep. I changed for bed and climbed in next to her. I awake the next morning horny. As I gather my senses, I'm hoping we can have a quickie before we leave for the cabin. I turn over and notice that Sara is already up. I walk into the bathroom and discover that she's already finished getting ready. I resign myself to no sex this morning and finish getting ready and head into the kitchen. I see Sara is at the table reading. I grab some breakfast and sit down next to her. "What time do you want to leave?" she asks me. "How about as soon as I'm done eating?" "Sounds good" she replies as she puts down her book. She heads into the bedroom reappearing a few minutes later carrying her suitcase. I finish breakfast, get my stuff together and before you know it, we are in the car on our way to the cabin. A few hours later, we're there. We carry in our stuff and start to get settled. As I start putting things away, I show her around the small cabin. "So, where is it?" she asks me. "Where is what?" "Your machine. I thought you said it was here along with a bunch of extra parts." Surprised, I show her everything in the closet where I store it. She looks at everything and asks "How long will it take you to set it up?" Surprise is pasted all over my face. "Only about 15 minutes" I reply. "Then get busy." I do as I'm told and take the machine out of the closet and start to set it up on the living room floor. I figure I can always move it later if needed. I finish getting the machine setup and ask Sara "What now?" "Get in." I am totally surprised. It takes me a minute to realize what she just told me. I've got a really dumb smile on my face too because the prospect of this has me so excited. Before she has a chance to change her mind, I get naked throwing my clothes on the sofa. I put the cuffs on my ankles and wrists. I lube up the butt plug when Sara asks to see it. I hand it to her, telling her to watch out for the lube. She inspects it; looking all over at it. I show how it vibrates and tracks pressure so that it can tell the computer when I'm about to cum. She asks if she can insert it. I can't believe this, she's never wanted to do stuff like this before. I mumble okay and bend over in front of her. She reaches over, spreads my ass cheeks apart with one hand and pushes the plug in with her other hand. When she's done, my cock is hard. She notices this, "Wow, you really do like this." That embarrasses me a bit but I don't let it stop me. I grab the computer and set it down next to the machine. I sit down in the machine, put the vibrator on my cock, and hook everything up. I reach over and start the program on the computer. As the program starts, I realize that Sara is looking over the shoulder at the computer. "Tell me how it works." I run through the options and settings with her. She asks a bunch of questions, maximum time it will run, what the different intervals are, and more. She tells me that she will set it up as she sits down next to me and turns the computer so that I can't see the screen. "Finish hooking yourself up" she tells me as she starts typing the settings. I do as I'm told and connect the restraint straps to the cuffs. In less than a minute, I'm laying down in the machine waiting for it to start. Before too long, the machine pulls my arms and legs taut and the vibrators start. It doesn't take long before I'm ready to cum and the edging begins. Sara is watching my reaction and watching the computer. I'm really enjoying the edging session. I'm moaning, moving against my bonds, and pleasantly frustrated. After about 10 minutes of this, the vibrators shut down and I'm slowly calming down after the edging. Sara moves into my line of sight and starts to undress The vibrators start up just as she gets naked. She moves back where I can't see much of her. Her being naked is affecting me. Watching her got me going and it only takes a few seconds before I'm ready to cum. Sara keeps looking over at me and smiling but doesn't move. The vibrators keep up their torture and I'm more and more frustrated. I realize now how different it is to be edged in front of somebody you love who excites you. It is taking the sensations to a different level. The fact that she is naked is just enhancing it even more. I'm getting more and more desperate to cum. I'm pulling against my bonds more than I usually do. I think I'm moaning more and louder than usual as well. Just when I think I can't take any more, the vibrators turn off. "Wow, that was only 10 minutes and you looked so frustrated. I wonder how much longer you could have gone?" she says to me. Before the vibrators start up, she moves next to me. "Watching you is making me horny too. Make me cum" she says while she sits down on my chest with her pussy facing my mouth. Her pussy is wet and her clit is already sticking out a little. That gets me instantly excited because it usually takes me a while to get Sara this excited. I start licking her pussy focusing on her clit as she likes. I feel the vibrators start up again. I'm ready to cum and getting edged before Sara cums. My desperation is making it harder for me to concentrate on licking but I do my best. I notice that our pleasure is starting to sync up. When I moan into her pussy, she moans too. We continue like this for a few minutes before Sara cums. Her orgasm is intense and seems to go on forever. Watching and feeling her orgasm is making me more desperate to cum. In fact, the vibrator on my cock shuts off so that I don't cum. The machine is still keeping me from cumming and I'm enjoying this frustration immensely. After her orgasm subsides, Sara moves off of me and back to my side. She smiles at me. I smile back but my smile is interrupted by moaning brought on by my continued edging. "Wow, that was great. Every time you moaned, wow, it was like I could feel your desperation. And that made me so... I've never felt anything like it." I don't reply; I'm too excited and my need to orgasm is growing to unbelievable levels as is my frustration. Seeing Sara so satisfied makes my frustration feel more acute. "Wow, your cock is really red and it's so swollen and big" she says as she moves back behind the computer. She continues watching as the session goes on and on, my frustration growing and growing. I can barely think; my whole being is becoming concentrated on my cock. I don't know how long this goes on before I finally feel the vibrators shut down to give me a rest. "That session lasted almost 14 minutes." "Oh my God, no longer." I plead. "I set the maximum session to 15 minutes so it shouldn't go too much longer than that" she tells me. As I calm down a little, I also realize that this is just the second time I've been in the machine since I optimized the edging. It is bringing me closer to orgasm than it used to; my changes definitely worked though I'm not sure yet if that is a good or bad thing. Add to that, Sara's control, and this is one of the most intense sessions I've ever had in the machine. Before I am ready, the vibrators start their sweet torture again. In no time at all, I'm ready to cum and the edging begins. Once again, I'm moaning and tugging at my bonds with my desperate need to cum. Sara continues to watch me. We stay like this until the session ends, more than 10 minutes later. "I can't take much more of this" I tell Sara as I'm recovering from the edging. "It's only been 48 minutes. I thought you told me you've done this for 90 minutes before." "I only went that long a few times. And you being here and cumming is making me more frustrated that I can't cum." Sara smiles at that. "Well then, it's a good thing you don't have much longer to go." After another few seconds, the vibrators start up. This time, it takes me nearly a minute to be ready to cum. As the edging begins, Sara moves to my side. She's is watching me get tormented by the vibrators. I see her looking at my cock too. After another minute, she bends over and puts a nipple by my mouth. I greedily suck it in, enjoying some distraction from the edging. Again, though, I start moaning around her nipple. Sara starts squirming around like she does when she's horny. After a couple of minutes like this, Sara makes me switch nipples. She is also positioning her pussy by my hand. The position of my hand prevents me from getting a good position to finger her; instead I rub the back of my hand up and down her pussy. Apparently that is enough as she starts squirming riding my hand a little. I'm enjoying the distraction; the vibrators are still running and I'm still not cumming but I'm not quite as frustrated. I'm still being edged though and still really, really need to cum. And then Sara cums. She moans so loud this time, louder than I've ever heard her before. That doubles my frustration especially with the vibrators still going and me hanging right before orgasm. We stay like this for a couple of minutes before a funny thing happens. The vibrators shut down. I didn't think it was long enough for the session to be over. Sara notices this as she gets sits back down next to me. She reaches over and, very carefully, removes the vibrator from my cock. Every time she touches my cock, I moan. "Wow" I hear her number as she continues to remove the vibrator. After a minute, it's off and my cock is hard, swollen, and dripping. "Please, stroke me and make me cum" I plead. Instead, she straddles me, positioning my cock at her swollen, wet pussy. Before I can prepare myself, she sits down, plunging my cock deep into her pussy. I can't help myself and let out a huge moan as I feel my cock enveloped by her pussy. "Wow, I've never felt you so big" she tells me. "It's like I can feel your pulse through your cock right now. It is just amazing." I have to agree; it does feel amazing. I've never felt anything like it. And I've never been as horny as I was right then. Sara starts to ride my cock. Given how desperate I am; a too short 30 seconds later and I feel the cum rising in my balls. And I cum HARD. My orgasm felt like it lasted minutes; I shoot and shoot. Sara keeps on riding my cock, not stopping until my orgasm is done. A few seconds later, before she's gotten off of me, the machine starts to loosen the restraints. Sara notices that I'm almost free and gets up. I'm totally spent and have to work up the energy to disconnect myself from the machine and to remove everything. Sara and I move to the bathroom to take a quick shower then collapse together on the bed. I'm asleep in a minute because I'm more satisfied than I've ever been before. At My Cabin - The Next Year Ch. 03 he next day, we went out for lunch. When we got home, Sara asked me if I was up for another session. "It was great but I don't think I'm not ready to repeat it. Maybe tomorrow." I looked right at Sara, smiled and said "How about if we the machine working for you today?" "I don't know. I don't think I'm into being teased like that." "Can we try?" She agrees so I get the spare equipment out of the closet. I grab the computer and set us up on the sofa. "Why aren't we using the machine?" she asks. "Not yet. First, I need to calibrate the program so that it recognizes your orgasms." I walk her through the steps. She gets undressed while I get the butt plug ready. I show her the butt plug and ask her to bend over so that I can put it in. "I've never had anything in my butt so be gentle" she tells me. I put some extra lube on the butt plug and start pushing it in. I notice that her pussy is wet and I run a finger down her slit ending at her clit. She reacts by pushing against the butt plug, almost sucking it in. I smile. I connect the sensor to the computer and give her a button to push when she starts to cum. That makes her blush but stops as I spread her legs and let my mouth work her pussy over. I'm licking her pussy lips and all around them. I force my tongue between her lips. When I think she's ready, I move my tongue to her clit and slowly lick it in the way she likes. As she gets closer to orgasm, I start to suck on it. It doesn't take long before she's cumming. When she's done, I take a look at the computer and smile; the readings look good though I suspect she pushed the button a little soon. I tell her that we need to repeat this. I unplug the sensor from the computer and tell her to go relax for a few minutes. She goes to pull the butt plug out but I tell her to leave that in place; it will help her get used to the feeling of it. A few minutes later we do a repeat and she cums again. The readings were pretty good; I think she was better with the button this time. Plus, because I am so familiar with her, I think I can skip ahead to having the program attempt to edge her with the vibrator. Worst case, it will make her cum and she will enjoy it. Plus, I can adjust as I go. But that is for later. For now, I disconnect the sensor and help her remove the button plug. I tell her that we'll continue this evening after she has had a chance to relax a bit. This must have really turned her on. Instead of getting dressed, she stayed naked. She also got me naked and started playing with my cock. She kept that up all afternoon, making me cum three times. She wouldn't let me fuck her though saying that she needed to save her pussy for later. I noticed an evil grin on her face when she would tell me that. We had dinner naked which we had never done. It was fun especially since I was able to keep rubbing things onto her nipples and lick them clean. We finished dinner with both of us horny. We moved to the sofa ready to try the next steps. I lubed the butt plug and slid it into her ass. Again, I noticed that her pussy was wet so I rubbed it again. She started moving against my hand but I removed it pretty quickly. I showed her the vibrator and had her sit on the sofa. I got the vibrator into position on her and adjusted the straps to keep it from moving. I told her that she was not allowed to touch the vibrator or her pussy through the next steps. Hooking everything up to the computer, I started the program. She jumped when the vibrators started. That told me everything was positioned correctly. "Oh my God, that vibrator in my butt, I've never felt anything like it. It makes the other vibrator feel like it's going through my whole body." The program is detecting that she's building towards orgasm but still has a little bit to go. I toggle a few settings; the program will now attempt to edge her for two minutes and then make her cum. In another few minutes, the edging routine kicks in. This makes Sara give out this huge moan. But event with that, I don't think she's that close to cumming so I tweak the settings. In another few seconds, after the changes have applied, she starts moving her hips around, trying to get more pressure on the vibrator. A few seconds later, she's reaching for the vibrator. I grab her hands and tell her to just wait. Her hips keep grinding while she tells me that she needs to cum. She's moaning quietly but almost constantly and within another few seconds, asks to cum again. A minute later, the vibrators ramp up and make her cum. I release her hands as she starts to cum. More than 20 seconds later, the machine turns off the vibrators. When she recovers, I ask her how it felt. "Amazing. Why did it take so long to make me cum though?" "The program was edging you. That's the only way I can make sure everything is adjusted." "Wow. It was frustrating but exciting at the same time. I can see a little of why you like it so much though I don't know if I could take the hour I put you through yesterday." I have a big smile on my face. I was not expecting her to enjoy this as much as she has. "When you are ready to try it, it won't go for that long. The first session should only be 15 minutes or so. We could try that tomorrow." She smiles back at me. "Ok. Now let's go take care of this" she says while pointing at my hard cock. We go into the bedroom and have some of the best sex we've had in a while.
