I knew she came to this gym, but I'd never actually seen her there before. It was a Saturday morning, not my usual time for working out. "Oh, hi. I was, but there seems to be a long queue, and I don't like the communal ones. I think I'll just go home and shower there." She nodded agreement. "Yeah, dunno why, just doesn't seem right." I hesitated. "Want to come back to mine? Shower there and then grab a bite? Mark's away so we could have a nice girly lunch." "Sure. Nat's tided up doing something all day. That would be nice." Nat is her husband and my little brother. We drove our own cars back to my place, and went in. "Shower in the bathroom's playing up at the moment, " I said. "The one in the en suite is better anyway. If you use that first and I'll just get a few bits out of the freezer for lunch while you're there. Clean towels under the wash basin." She made polite attempts to suggest I should go first but I brushed them off. Two women at home by themselves? Talk of a shower? I know what you're thinking and you're wrong. I found some bits for lunch, put a bottle of wine and some beers to chill quickly and did a rapid tidy up of the living room. Turns out I was tidying the wrong room. Annie appeared wearing a towel, smiling happily. Smirking almost. Odd. "Finished! Love your shower." It was nice - we'd just had it done. I went into the bedroom to take my turn, undressed, and nearly died of embarrassment. Hanging on the radiator - put there by myself that very morning - was what Annie had presumably been smirking about. It was my favourite strap-on harness and a very large black dildo; I'd washed it in the bathroom after giving Mark a good seeing to, and then left it there safely to dry. Stupid, stupid, stupid. Ah well. Annie was cool. Just suppose it had been my Mum ... I showered, pondering whether to mention it or just pretend it hadn't happened. I was still unsure when I came out. It was a lovely sunny day, so I just slipped on a skirt and tee shirt, hair not done properly and no make up. I like not having men around sometimes. Annie had dressed but was still smirking, which made my mind up. "Sorry, didn't remember I'd left that out. Oops." "That's OK. You guys had some fun last night then?" "And this morning." "Good God, really? So who's the big strap-on fan then - you or Mark?" Are we really going to have this conversation? Looks like it. "I suggested it. He was reluctant, but once he'd tried it he couldn't get enough." "And were you as keen?" "I adore fucking him. He's got a sexy arse as well." "It looked pretty big?" "Yeah, that one is. We started small, but just got carried away. I take it from your reaction that you've never tried it?" "I've suggested it." "And Nat said not?" "Exactly" "He doesn't know what he's missing." I poured some wine and we moved outside to sit in the sun. "Actually, Nat and I are having some difficulties, sex-wise." "Really?" Nat is as attractive as Annie - which is very attractive. He'd had had a string of sexy girlfriends before settling down. I just somehow assumed that they would be doing fine. "We have different views." "Ah. Yes, Mark and I had a phase like that" "You did. What happened?" "Hey, I didn't mean to talk about me. You go on." "No, I want to know. You've obviously solved it. What did you do?" "Just between us? No pillow talk to Nat about his sister's slutty behaviour?" "Is there slutty behaviour involved? Anyway, yes, no pillow talk." "Well it seemed that whatever I wanted he didn't; whatever he wanted, I didn't. So we did a deal: we'd both try absolutely anything that the other really wanted. After trying it properly if we still didn't like it we'd move on. I mean we didn't try everything. It had to be something that we genuinely believed that the other would enjoy if they would only have a go. And one of mine was to fuck him with a strap-on." "What else?" "What did we try or what did we settle on?" "Both?" "You keep secrets?" "Yes!" "Threesomes, bondage, exhibitionism, anal and watersports. Oh and some home-made vids." "And what was good?" "Well, I hate watersports. Well, I hate being pissed on, at least. And I don't hate anal, but his cock is just too big for me there. And bondage it turned out that neither of us actually liked it when we had a go." "So you're left with porn, threesomes, strapons and exhibitionism" "No comment" "Is that why you've got no knickers on?" Oh God. "Sorry. If I tell him later that I've spent the day without them on he'll get such a boner. I'll go and put some on. Sorry." She stopped me. "No, don't be silly. Fine with me." "So what does Nat want that you're not up for?" Now she went coy. "Well, it all seems a bit tame after what you said." Thank God I'd left out the cross-dressing. "I bet he's got a list of kinks he'd like to try and isn't telling you then. And I bet you have as well." "I'm not sure I have. I just really, really want to do his ass, but given that I've never done anyone's I'm not sure I'll even like it - perhaps it'll turn out like you and bondage: you try and then just wonder what the fuss was about." "Well, there are ways. I could lend you Mark." "What?" "You can fuck Mark's ass with my strap-on. Just as a test." "Er, I really don't think Nat would be cool with that." "No? OK. How about mine?" "What?" "Oh come on, two women? Every red blooded male's fantasy?" "I'm not gay!" "Neither am I. Look, I could dress as a man, you do my ass, who's to tell what genders we are? You'd at least have a clue if you liked it, even if it wasn't entirely realistic." "Er ..." "I've got to say, though, there are two conditions." "What are they?" Ha! I had her. "First, it's got to be a thin dildo. I can't do large things up there." "You should borrow Nat. Sorry, didn't say that. A thin dildo is fine." "Has he got a small cock?" "No, it's dead normal. Just my boyfriend before him had an enormous one, and the thought crept out. Ignore it, please." "The second is weirder. You know I said threesomes? Well, yes, we've done them, and no that's not what I'm suggesting, but it's sort of related. Mark's cool with me doing anything with anybody and a strap-on. But the deal is that if he's not there he has a video of it. He thinks its the sexiest thing he has ever seen." "You want a video of me fucking your bum so you can show it to your husband?" "No vid, no fuck. Solid rule." "Jeez, you two are complete perverts. OK, but I don't want the dressing as a man bit. That would be weird." That was the weird bit? She's obviously more my kind of girl than I had given her credit for. "OK. Plenty of light out here and it's totally private. Get stripped and I'll be back in a second." I rushed into the bedroom and grabbed a camera, tripod, lube and strapon; I half expected that Annie would have had second thoughts and fled, but she was there, naked and inspecting her pussy. "I should have waxed." She was worried about what she'd look like on camera. "You look pretty good to me, but anyway this will hide any stray hairs", I said, handing her the harness and dildo. She looked fucking tasty to me as I took a few shots while setting up the camera. She looked slightly bewildered at the harness, and they can be slightly puzzling at first, so I knelt in front of her to help put it on. Having the chance to inspect her closely I didn't know what she was moaning about, as she looked perfectly groomed to me - a little landing strip, but basically bare. Her pussy was already slightly damp, and I didn't think it was remnants of the shower. I fumbled around putting the harness loosely around her, inserting tge dildo and tightening it up. "Is it on your clitty properly?" "I think so." I grabbed the end of the dildo and moved it around, grinding it in to her, then looked quizzically. "Yes. That's the spot." "Now, if it was Mark I'd make him suck it a bit first, 'cos that really turns me on. But you've got to do what turns you on. Just pretend I'm Nat." "Get on you knees and suck my cock." I did. Sucking a strap-on is kind of weird; it's a far more a psychological turn on than a physical thing, but what's wrong with that? "Deeper. Take it all in." In truth it wasn't a big one, so I could do that without much difficulty. I had my hands on her arse and pulled her into me, making sure that the end of the dildo was getting her clit properly. "Harder, Nat, harder". I gripped it hard with my teeth and moved it around, trying to work out where she wanted it. I also pushed one hand up my cunt for lubrication then slowly moved it around her arse. She didn't protest, and in fact seemed to give a moan of encouragement. A sigh. Had she cum? I thought so, and slackened slightly. After a pause, I looked up to see her smirking at me. "Well done, Nat, good job. Now, over the table. I'm going to fuck the shit out of you." "Be gentle?" "I'll start gentle, but then I'm not holding back. Now stay there so I can point the camera at your sexy arse so your kinky sister and her husband can perve over you later." "Can I put some lube on you cock?" "Yeah go on, then I'll lube your arse." It felt weird doing the cock, but then she firmly turned me over and lay me on the table, face down. "Nat, you have one sexy bum. Now rub you little cock while I'm doing this, but don't cum till I say." I put my hand on my clitty as she rubbed lube into my arsehole. Fuck, this was good. After a bit I felt her fingers withdraw and the end of the cock enter me. She'd obviously paid attention to instructional videos of some kind, because she did it dead right. Slow and gentle at first, gradually going in deeper and harder. "You OK, Nat?" "Loving it. Do me." She gathered speed, thrusting harder and harder. I don't know if she'd really meant me not to come, but I did, several times. Hard. Eventually she slowed down and stopped, and after a pause I felt her withdraw. I turned round and she seemed in a daze. "Was it how you expected?" "Fuck no. It was a hundred times better. Oh my god I can see why you do that at night and again in the morning." "And then in the afternoon with my sister." She giggled. I got some tissue and wiped down the dildo, then moved to unbuckle her, but she stopped me. "Hey, leave my cock alone. I want to see what I look like." She went into the house and stood in front of the full length mirror. "I look so fucking sexy like this. Why would he not want me?" I had to agree - she looked fabulous. We sat in the living room - me still naked, her still wearing the strap-on and watched the video we just made. "Show it to Nat." "No. Really, he'd be a lot less pissed than if was Mark, but I'm still not sure he'd go for it." "Let me show it to him?" "You're kidding?" "He listens to his big sister" "Well, maybe, but surely you can't show him a video of us fucking and hope to get away with it." "Bet you I can not only get him to watch it and enjoy it, but he'll rush home and demand you do him there and then." "Or more probably he'll see his incredibly sexy big sister humping and forget that incest is a big no-no." "Mmm" "You pervert! I suggest incest and you just rub your cunt and say 'mmm' with a smile on your face. Would you really do him?" "Would you mind?" "If you can make him want to bend over and take my cock up his arse, then you can do anything you like to him as persuasion." "You know I'd have to video it?" "Send me a copy?" "No, but you can come over and watch it with me afterwards" "Perhaps we could try and re-enact it?" "And Mark could video it for a proper professional job?" Fuck yes. This was going to be good. ***** To be continued. Strap-on Brother Ch. 02 "What you doing today?" "Fucking you. All day." I'm a doctor and work shifts, so despite being mid week I had a day off. Unfortunately my husband did not. "Afraid not - I'm working all day." "I'm so fucking horny." "You've been horny since Annie fucked you up the arse. She really got you." "Annie fucked me up the arse because I was so horny. Come on, a quickie?" "I really have to go - I'm already late." "Spoilsport. Pass me a dildo then." "Front or back?" He'd pass me a smaller one if I said back. So considerate and understanding. "Hm. Actually, both." "Tart." "That's why you love me." After doing myself I got up and wandered around a bit, aimlessly. Actually I'd worked an awful lot of hours just recently, and really did just need a bit of chilling out time. It was a beautiful day, so after a few necessary chores I got myself organized, stripped off the skimpy dress I'd been wearing and lay out in the sun. The garden is completely private so there was no issue with nude sunbathing. It also meant that there was no problem with bringing out a few toys to play with. After a bit I was satisfied - for the moment, at least - and dozed peacefully in the sun. Sometime later I was woken by the doorbell. Tempted to ignore it, I realised I could do with a drink and a break from the sun. I was also tempted, just for a second, to answer it naked, but common sense got the better of me and I slipped my dress on - it was thin, but better than nothing. As I got up a pleasing sensation in my arse told me I'd dozed off with a butt plug in place; common sense did not prompt me to remove it before answering the door. "Nat - what brings you here? Come in". It was my brother. "Is it OK? Mark texted me and said that you were bored as everyone else was at work, and if I wasn't busy I should come and surprise you." Did he indeed; how very interesting. "I have pastries." "I'll make coffee then" While making coffee I noticed Nat's eyes drifting downwards, and realised that I was not really very decent: the dress was skimpy at the best of times, but a mixture of sun cream and perspiration - hey, it was a sweltering hot day! - had made it rather clingy. OK, very clingy and rather transparent. I should have gone and changed. I didn't. I was beginning to enjoy myself. We sat in the garden with our coffee and delicious Danish pastries talking gibberish. He was still checking me out, probably because I was accidentally-on-purpose flashing him whenever possible - leaning forward so he could see my tits, legs angled to make the most of them and probably more than a hint of pussy. I got up to get some more coffee, and when I turned round - bottom facing him - he called out in surprise "Jools!" "What?" "Are you wearing a - no sorry, ignore me. Actually could I have juice, not coffee?" "Am I wearing what? I'm just wearing this dress - I only put it on to answer the door." "Sorry, probably just the way it fell." I knew he'd made out the base of my butt plug; the dress was so insubstantial it would definitely show. I could have easily dropped the topic, but really didn't want to. "How do you mean?" "I'm sorry, I'm just an idiot. Just the back of your dress looked a bit odd, but it was just a trick of the light." I felt around my bottom - through the dress - and then affected surprise. "Oh, it's a butt plug. Sorry, didn't realise you'd be able to see it. Back in a sec." I returned shortly. I had fucked his wife, Annie, ten days ago and just as I had half expected her to flee when left alone, so I wondered if Nat would have scarpered. He hadn't. He was quite matter of fact, but smiling. "You mean I've been sitting here talking to my sister while she's squirming around with a toy up her arse? I wondered why you couldn't sit still." "Sorry. I fell asleep with it in while sunbathing, and then the doorbell rang. I haven't had a chance to take it out." "You sunbathe with a buttplug in?" "Well, not always, obviously. But today ... Sorry. Anyway, you could tell what it was from a distance so I'm guessing you're no stranger to them. Everyone likes a bit of backdoor stimulation, but for some reason we all have to pretend otherwise." "I don't" "Don't what?" "Shove things up my backside." "You're missing out." "Annie says that." "She thinks you should try one?" "She wants to do me with a strap-on." My, he was getting frank all of a sudden. "And you won't let her? You idiot!" "Oh come on. I bet Mark wouldn't let you do him." I smirked, and reached down for my ipad. I quickly found what I was looking for and passed it to Nat. "Does he look like he's not enjoying that?" This was a particularly good video; for one thing it hadn't been shot with a still camera. The next video showed the cameraman getting his reward while Mark recorded, but I wasn't going to show that one to Nat - well, not for a minute or two anyway. "Fucking hell Jools. First what are you doing videoing it, and second why are you showing me?" But he made no effort to stop looking, and I suspect he had no idea he was rubbing his cock through his trousers. "Because I don't want my little brother to miss out on the good things in life." "You are both really getting off on this, aren't you?" "Oh yeah. Mark loves having his ass fucked. And he loves watching me do a nice arse." "You mean you do other people? And he's cool with it?" "God yes. I never have cock in pussy sex with anyone but him, but he loves watching me butt fuck people." "Dear God you two are perverts." "We sure are. You should try it." "Hm. May be I should. Doesn't it hurt him?" "Of course not. Well not if you do it properly. Look, why don't I give you a quick demo - then if you like it you can tell Annie you'd love to indulge her; if you hate it forget all about it." "You want to fuck my butt?" "I would love to fuck your butt. And you would love me fucking it. I'm really, really good." "Jesus. What would Mark say?" "Mark would say the same as he always does - show me the video!" "You want to record it?" "Have to. I can strap-on anyone, but only if I record it for Mark." "Fucking hell." he paused. He rewound the recording, watching it again, thinking. "Really? You promise I'll like it?" "Promise. Now, go have a quick shower while I get set up, come out gleaming and prepared for the start of a great new thing." I went and got a harness and pondered which dildo to use. I fancied the idea of using the same one his wife had fucked me with, but got a selection of other sizes for educational purposes. I also got the camera and set it up, plus I also put my phone and ipod recording at strategic places. I wanted to catch as much of this as possible. He came out with a towel wrapped around his waist, looking slightly sheepish. "I'm not sure this is a good idea, you know" "Well, I am. Now, let's lose that towel." I removed it and weighed him up. Nice fit bod, cock was as Annie had described - not big, not small, just normal. Pretty hard though. "Right, I'm wearing the cock I like receiving myself, but I have smaller or larger if you'd prefer." I played with the cock I was wearing. It was actually about the same length as Nat's, but slightly thinner. I wandered behind him - he had a really sexy arse - firm and tanned. Were he and Annie into nude sunbathing? An area to explore. "Now lube is really important. Really. Enough and you'll love it; not enough and it'll hurt." I grabbed a tube and squirted a big handful, then started working it into him. Although my goal was to get him ready, just then I was concentrating on giving him a good time. "Rub your cock while I'm doing it, but only slowly. No cumming at present." Slowly, very slowly, i put a finger up him. He tensed just slightly but carried on rubbing his cock. "OK?" "Very" "OK, I'd like you to bend over this table so I can get at you better. Remember, if at any moment it feels uncomfortable tell me at once. You may need more lube, you may need a break, but you must tell me. Got that?" "Yes, Miss. I'll be good." He knelt over, and I put more lube on him, plus a load on my cock. Then, very very carefully I put just the very tip of my cock in him. Again a very slight tension but no real resistance. Slowly I eased in a little bit more, then removed it completely and put on more lube, and again penetrated him. Now, little by little I moved further in, and then withdrew - but not fully this time. "How is it?" "Different" "Different good?" "I think so. Carry on." I put my cock in, and meeting no objection went all the way then paused. "Don't stop!" I withdrew slightly and then - well, then I fucked him. Slower and more gently than I would Mark, but it was a definite fuck, not a vague messing about. I wanted to grab his cock, but couldn't reach round. But he was tugging on it himself, and was hard. (Not all guys are hard when you fuck them. They're still loving it, just not hard.) "I'm coming." I took this as a sign to increase tempo, and gave several much harder, deeper thrusts, till he collapsed away from me, obviously spent. I stopped moving and let him recover. "Bloody hell! Why didn't anyone tell me it was like that?" "You enjoyed it, then?" "You noticed, eh?" We paused a little bit longer, then I slid it out, wiped down my cock and watched him. "Well, it was good," he said "but we really shouldn't have. You looked so hot in your slutty outfit, and then you showed me you doing Mark. What the fuck would Annie say if she ever knew?" "Oh, I think she'd be OK." "No, I really don't." For an answer I reached down to my ipad again. First I showed him the recording of her fucking my ass, which he watched in stunned silence. Then I showed a special little recording she'd made for me, but addressed to him. She beamed out of the screen. "Hi Nat! If you're seeing this it means that Jools just fucked your arse. I hope you enjoyed it as much I enjoyed doing her. Obviously I'm cool with this, and if your arse isn't too worn out I expect to be able to give it a good seeing to tonight. Love you!" "You bastards - you set me up!" He wasn't really mad. "If anyone did it was Mark. I had no idea you were coming over today, and was slightly worried how I was going to deliver on my promise to Annie. But it seems to have gone OK, don't you think? Aren't I the best big sister in the world?" He stood up and walked over to me, giving me a tender kiss on the lips. Strange, but standing there being kissed gently by my naked brother seemed the oddest moment of the morning. It was tender and loving, and as I grabbed him firmly for a proper hug I felt protective of him, but just a little bit nervous. Had I fucked things up between us? Was this a one-off, or was it the start of a whole new aspect of having a brother I loved deeply? -- to be continued. Strap-on Brother Ch. 03 "I've got a request." My sister and I were sunbathing naked in my garden. We'd had a couple of drinks and were nicely relaxed. "Uh huh." "Most people would think it pervy and disgusting, and although I know you are perverted and disgusting it may even cross your strange code." "Try me." My hand went to my pussy in anticipation. "Well, you know you said that you didn't like big things up your bum." "Yeah." "And your husband has, well, a big thing." "Yeah." I genuinely didn't spot where she was going. "And I do like big things up my bum ..." Ah. Got there now. "You want Mark to fuck your arse?" "Well, yes, if you wouldn't mind, but that's not all of it." Dear God, what else? "Well, I wondered if we got a dildo that was exactly the same size as Mark ..." "Already have one." "Great. Anyway, if Mark fucked my arse at exactly the same time as you fucked Nat's with an identical sized cock. Sorry if it's too weird - I've just been playing with the idea." "And playing with yourself with it, I notice." She was squirming nicely on her hand while telling me. "Mmm. What do you think? I mean, doesn't Mark miss having an ass to fuck?" "Yeah, probably. I don't encourage him to fuck other women's bottoms." "Oh, Sure. Sorry." "But it does sound sexy. Can I think about it?" "Of course." "Would you like to try the Mark sized dildo anyway?" "You want to fuck my ass, you mean?" "Well you did do mine," "Well, Nat doesn't encourage me to let women fuck my bottom. But it does sound sexy. Can I think about it?" "Touche." We dozed in the sun, each thinking dirty thoughts. Later she said, "How big is his cock? I mean I saw it in that video, but I couldn't really tell." "I've seen bigger in porn, but never in real life. I've seen quite a lot, but obviously not enough, because statistically one person in a hundred is actually bigger than him. Look, I really have got a dildo exactly his size, I'll show you." I went into the house and fetched it, on the way back noticing how sexy she looked, lying there naked and rubbing her cunt. I decided. "Annie, can I put this on now and fuck you up the bum?" "Does that mean Mark will be doing the same thing some time later?" "Yep." I'm not going to give you a blow by blow of what happened next, I'm afraid. It was good, and boy did she like having that large thing up her - came like her life depended on it. I'm sorry you're going to miss out on that as I'm going to fast-forward to the following Saturday. But first I need to tell you of a little conversation we had after I fucked her. I was having slight concerns over Nat's feelings - after all, she wanted Mark's cock specifically because it was bigger than his. Nat's cock is perfectly nice, but I worried he might get a complex about it. Annie claimed not. "Look, Nat's got a nice but normal cock, and I have a bit of thing for big ones. I've got slightly small tits, and Nat's excited by much larger ones. I don't take his predilection as a judgment on me, so I don't see why he would judge mine." For some reason I suddenly remembered Annie's sister, Chelsea, has massive tits, and said, "So if, for the sake of argument, he wanted to cum all over Chelsea's tits, you'd be fine with it?" There must surely have been some sibling envy at some point. Her hand went down to cunt again as she considered. "Interesting thought. If you'd asked me a couple of weeks ago I'd have been horrified, but since you've been corrupting me I'm not so sure. Anyway, Chelsea's a complete prude - no chance there." I'd only met Chelsea a couple of times, and to be honest her tits were the only thing I really knew about her. Suddenly the thought of my brother coming all over them was a big turn on. I kept thinking about it in the days coming up to our little foursome. -- All I had told Mark was that Annie and Nat were coming over and he was going to enjoy it. Obviously I'd recorded me doing Annie, and he'd enjoyed watching that. I think he imagined a repeat performance, and was quite excited just by that idea. "OK, we have an activity for the evening, and the rules are simple." Simple, but fixed for the result I want. "Everybody will get their ass fucked, and everybody will fuck one ass. And unless there's a huge problem you get one veto on who fucks you. And I'm sorry Mark, but I'm vetoing you." Nat looked surprised, and said, "Well I don't know if that's what Jools had in mind, but I'm vetoing you as well, Mark. Sorry mate." Mark pretended to look crest-fallen, and turned his puppy-dog look on Annie. She smiled, and said, "OK big boy, I'll put up with you, I guess." I looked at Nat, affecting surprise. "Well, brother, I guess that means that in round one I get you. Pucker up!" "And in round two, do I get you?" I looked at Mark, and he nodded approval - he wasn't going to miss a chance of Annie returning the favour on his back-side. I led the way to the bedroom, pulling off my dress as we went. In no time at all I had the harness in place with the massive dildo jutting obscenely from it. Nat looked slightly concerned, but Annie reassured him that he'd be fine. I said, "I want you on your back this time, brother. I want to play with that cock while I'm fucking you." And I want to talk to you. About Chelsea. Mark and Annie were all over each other by now, and I must confess to a slight pang of jealousy: not only is she super hot, she was indulging him with something he loves and I can't deliver on. Ah well, can't have everything all the time. I was taking it very slowly with this huge cock up Nat's arse. We used industrial quantities of lube and took it very slowly for a good long time. I was playing with his cock, and having an admittedly rather staccato conversation. "So, " I said, "Strap-ons were Annie's fantasy. What's yours?" "Haven't any," he said. I gave a slightly harder thrust to concentrate his mind, and said, "Liar." "OK, leather and latex." I changed my angle slightly, and he added "Ooh, that was good." "Leather and latex are always good. But real people - what would you go for?" "Annie is perfection. And you're pretty hot." "And if Annie gave you a free pass on any woman, what sort would you go for?" Now even though Annie was having a great time being sodomized by my husband's huge cock she was still paying attention. "Tits", she said, "He likes huge tits." I felt him thrust back a bit at me as Annie said that. I said, "Really? You don't like my tits?" My tits are great, but they're not huge. I played with them a bit while thrusting harder. He said, "Your tits are beautiful. But I do like really outsized ones." I moved my hands down to his cock, and tugged hard. "Like Chelsea's?" "God, yes," he said. "What would do with them?" "Come all over them. Then lick it off." I was wanking him furiously as he said this, and he came wonderfully. As did I. I stopped fucking him and we both paused to take a breath. He looked a bit sheepish. Annie, still being fucked by Mark, looked over and said, "Nat, you came on Jools's tits. Will you lick it off, please?" I looked down and saw that there were big globules of cum on me. I wasn't sure if Nat actually wanted to do this or not, but he sat up and licked me clean. Then to my further surprise Annie managed to get herself close enough to give him a kiss, and it was obviously that they were pushing his cum from mouth to mouth. And she called me a pervert. After a good pause we resumed again with roles reversed. Nat's cock up my arse was very good, but I've got to confess it didn't reach the same highs, so I won't go into any more detail. Instead I want to tell you some more about Chelsea. As I said, I didn't really know Chelsea, but I wanted to see how Nat reacted to her giant tits. I've wondered since then why I wanted this, and I've got to say I can't quite answer that. For some reason the idea just completely got me going, and fortunately I managed to persuade Annie that it would be a great idea. Annie tipped me off that the two of them were going clothes shopping, and I accidentally bumped into them. We got talking, and Annie said that she needed a new bikini. I made to go, but she said, "Will you just give me an opinion on this before you do? Chelsea only ever wears one-pieces." I looked at Chelsea, trying to say that I wasn't here to crash their shopping trip, but she shrugged, unconcerned. I then risked things, saying, "You never wear a bikini? You'd look amazing!" "I look deformed. Really." We went into the changing rooms and Annie slipped off her top. As she did so, Chelsea said, "No tan lines? Been going topless?" Annie had pulled her skirt off by then, but kept her thong on. Now she pulled that aside slightly, said, "And the rest," and smiled. "A nice all over tan." "Where do you do that, then?" "Jules has a very private garden." Chelsea looked at me and nodded. I couldn't really work out her reaction, but said, "Look, you can't get a proper tan in a one-piece. If you don't like bikinis why don't you two both come round this afternoon and see how you like the au natural approach?" She looked surprised, but not offended. "I wouldn't want to impose." "Not imposing at all. Just us three having a margarita and topping up on Vitamin D. Avoids rickets. My husband's out all afternoon." "A margarita would be good." "Then it's a deal. Annie, that bikini looks great. I'm going to leave you two to finish your shopping, and I'll see you whenever you get there." I drove home quickly, explained the position to Mark and got him to bugger off for the afternoon. It was yet another beautiful day, so I put the sun-loungers out and then started to plan how to get the conversation round to my chosen topic. Accidentally leaving a strap-on out worked out well with Annie, but I was less sure with her sister. In the end I took my box of toys out in the garden, but left the lid closed. An hour or so later the bell rang. I'd been naked, but slipped on a skimpy dress. We made some drinks and went outside. I asked Chelsea, "Would you be offended I took my dress off? I haven't anything else on." She smiled. "No that's fine. In fact, I think I'll join you straight away." Behind her I could see Annie's shocked look - she obviously imagined her sister would chicken out. I tried not to stare, but her boobs had become quite an issue of late. I've got to say I don't really get some men's obsession with big tits - they can easily looks saggy and unattractive. But Chelsea really did have a great pair. I didn't like to ask what size they were, but they were large and attractive. I've got a strap-on you can fill with liquid - usually milk - to make it ejaculate, and the idea of fucking her chest inserted itself into my brain before I could stop it. A small dribble from the corner of my mouth told me I was getting getting carried away in my thoughts. I tore myself away, lay back, took a sip of my drink and tried to act cool. We chatted, had a couple more drinks and just generally relaxed. After half an hour or so Chelsea sighed and said, "This really is very pleasant, you know. I've wondered about nude sunbathing, but somehow the chance never presented itself." Annie and I both mumbled agreement, and then Chelsea further surprised us. "Trouble is, it seems to make me really horny. I'll have to go home soon." Annie said, "Someone new?" She laughed. "Some chance. No, I'll be able to take care of things by myself." Annie said, "Well you can do that out in the garden. There's only us girls." She sat up, genuinely shocked. "You frig yourselves outside?" I tried to look slightly guilty. "Sorry, we're just a pair of pissed perverts. Ignore us." She relaxed. "I'm not offended. It's just that Annie's a bit of a prude." She looked across at her sister and shrugged. "Sorry, you just always give that impression." Annie's mouth fell open. "Me, a prude? I'm surprised you say that. Jules, who really is a pervert, can say that, but Chelsea, surely not you?" Chelsea smirked slightly, then said, "Oh come on, all those disapproving looks you used to give whenever Marcy stayed over." "Marcy? Your annoying friend back in Year 13? What's she got to do with anything?" "Well what the fuck do you think we were doing up in my room quite so much?" "You were having sex?" "Of course we were. She was amazing, but after you were so negative we started going to other places." Annie was lost for words, so I took over. "So are you still into girls, or was it just this Marcy?" She looked at me, and said, "What do you think's made me so horny? I've seen you eyeing up my tits, but since you haven't made a move I thought I'd better not mention it." She sat up straight and caressed herself. "Are you really a pervert? You want to play?" Before I could answer, Annie said, "She's a strap on fan, Chelsea. She'd like to fuck you with one." Chelsea licked her lips, and I said, "Well, yes, but it's kinkier than that." And I explained the video rule. When I'd finished, she said a simple, "Well, we've even got Annie to act as camerawoman. Let's get on with it." And so we did, and it was fan-fucking-tatstic. She lay on her back while I fucked her pussy and kissed those amazing tits. I shot my amazing ejaculating cock all over them and licked her clean. Then she repaid the compliment. Annie had been filming all this, and although she'd been rubbing herself she clearly wanted to get off. Chelsea obviously saw this as well. She got me to lie on the ground and put Annie on top. It was actually quite a while since I'd licked a pussy, but I was so turned on I wasn't going to argue. Then Chelsea came behind and put the strap-on at edge of her sister's cunt, then slowly moved in, giving me a beautiful view of the proceedings. I've no idea how long they fucked for, but Annie came several times, flooding my mouth with copious quantities of delicious pussy juice. Eventually they collapsed in a heap, and shortly afterwards we went inside and showered. Soon after Mark returned, and we sat around for a bit. To my surprise Chelsea said, "We made a little video." He smiled, and said, "Nat will love that." Chelsea looked puzzled. "Nat? Why Nat?" I could see Annie's horrified look, but Mark couldn't. "The thing about your tits? His desire to come all over them?" As soon as he said it Mark realised what he'd done. "The thing you obviously didn't know about. That thing." He looked at Annie and said, "Oops." Chelsea also looked at her. "Your Nat wants to come all over his sister's tits, and I discover this from my sister's brother-in-law? How did I not know I'm part of a family of kinksters?" Annie shrugged and smiled weakly. I said, "So are you up for it?" She smiled. "God yes."
