Review: This is part two of the Backseat Mommy series. In part one, Backseat Mommy: A Long Hard Ride, a mom is forced to sit on her son's lap for a long drive. As the day progresses, she is unable to resist the temptation of her son's cock. Note 1: Thanks to Robert, Tenzin, goamz86, and Wayne for editing. Note 2: There is a lot of texting in this story. If Cory is texting it will have a C: and be underlined. if it is from the Mom it will have a M: and be in bold and centered. Backseat Mommy: Ass Fucked I woke up the next morning washed full of guilt. I had willingly fucked my son in the backseat of the car while my husband drove. I had snuck out of our hotel room while my husband slept and went into my son's room to fuck him again. With guilt controlling me, and a tingle in my pussy at reminiscing about yesterday and last night, I climbed under the sheets and took Alex's cock in my mouth. I had only woken him up like this once before, the day after our wedding, and he had joked for years since (decades actually) that I wake him up properly. Feeling his completely flaccid cock slowly grow in my mouth was always a turn-on... I loved the power of making a cock get hard with my mouth. I heard soft whimpers and wondered if he was having a sex dream or was waking up. After a couple of minutes, he groaned, "Oh my, Sarah, what's gotten into you?" The true answer was 'Your son's big dick', but that didn't seem like the right answer to give, so I purred, "Just hungry for a morning snack." "I'm not complaining," he groaned, as I slowly bobbed up and down as his cock became fully erect in my mouth. As was always the case when we had morning sex, which was rare, he didn't last long quickly spewing in my mouth. I swallowed the entire load and asked, "Wanna join me in the shower?" "Sure," he nodded, with a big smile on his face. He returned the favour in the shower, using the removable shower head. We met Cory downstairs for breakfast and the moment I saw him I already knew I was going to fuck him again. I couldn't explain it other than undeniable lust. The sex yesterday had been exhilarating whether in the backseat with the potential of getting caught or in the hotel with the intense sex of having my son take control of me. I had no idea what he had in mind for me today... but my pussy was already wet with anticipation, the thong I was wearing, likely temporarily, was already damp. Alex asked, as we ate, "You sure you guys can do another day squeezed back there together?" I responded, "It is a little tight," which could be taken as I meant it, just a true statement, or as sexual innuendo as Cory took it. "True, but the longer we go the looser it gets," he quipped, making me instantly blush. "That is true," I laughed, trying to hide the blush. "Well, we are over one-third there," Alex said, excited to end the trip and spend some quality one-on-one time with his suddenly amorous wife. We were on the road in ten minutes, me again on my son's lap, when he texted me: C: Thigh highs again? I responded back: M: Easy access for your big dick. He responded: C: No regrets? I texted back: M: Not doing it sooner. I felt like a high schooler again... waiting for my boyfriend to make the inevitable move. A chill went up my spine as I felt his hands on my hips. A chill went up my spine when he lifted me up. I glanced at my husband, who was focused on the road and the down pouring of rain. I felt him pull my thong aside and slowly lower me on his fully erect cock. He texted me, once I was sitting entirely on his dick: C: Let's just sit like this for a while. I nodded. And for the next hour I sat on my son's cock. I wanted to ride on it, or grind on it, yet I just sat on it. I tried to read a book, but that was useless. Instead, I just let the longest tease of my life drive me wild. When the rain finally stopped, Alex said, "How you guys doing back there?" "Just making the most out of a tight spot," my son quipped. "Yes, it seems even a bit tighter back here than it was yesterday," I said back. "Should we stop?" Alex asked. "There is a truck stop in about fifteen minutes." "No, we should try to make it until at least lunch," I said, hoping to have an orgasm or two before then. "Yes, I can last as long as necessary, Dad," Cory added. I was worried that meant he wasn't planning to fuck me during this long, dreary drive. I added, really talking only to my son, referring to blue balls, "Don't last too long. You'll go all numb." "Oh, I have incredible stamina," Cory responded back. "Okay, well, let me know if you need a break," Alex said, just as it started to downpour again. "Sounds good, honey," I agreed, before adding, being the nagging driver wife, I usually was when I was in the front seat, "Focus on the road." "Nothing else to do," he said. I began slowly grinding on my son's cock. I was surprised when he grabbed my hips and held me in place. I grabbed my phone and texted him: M: Why? Mommy needs it now!!! He moved one hand away and then showed me his phone: C: All good things CUM to those who wait... and obey! I sighed. I was horny as hell and wanted it now! Yet, instead, I again just sat there like a firefighter with a hose but no water. Another half hour passed, although it seemed like three, before Cory put his hands back on my hips. I thought to myself 'About time'. I prepared myself for him to start slowly fucking me, but was surprised again as I felt his finger probe my asshole. 'He isn't seriously thinking of fucking my ass?' I thought to myself. Although I hadn't had anal sex since college, Alex actually rejecting me when I offered him my backdoor during the third day of our honeymoon in Niagara Falls, I did fuck myself in the ass on occasion when home alone... my favourite way to get off being to double penetrate myself... usually fantasizing about being dp'd in real life... a fantasy that I had never fulfilled. I tried to relax and allow his finger in, having had my much bigger vibrating butt plug in there just last week. Yet, without lube and at this angle it was not going to be as pleasant. His finger teased for a couple of minutes, but didn't enter, before he lowered me back on his throbbing cock. He then texted me, as my pussy was again full: C: Put your phone on mute. I did. He texted again and we started a lengthy texting conversation: C: Have you ever been fucked in the ass? I pondered whether I should tell the truth. I figured no reason to be prudish or conservative now. I responded: M: Not since college. M: With a real cock anyway! C: Dad doesn't fuck your sweet ass? M: Your father thinks it's disgusting. C: I don't know how we have the same DNA! M: I'm beginning to wonder if you were not switched at birth. M: LOL. C: So when was the last time you had something in that fine ass of yours? M: Last week. C: Details. M: It was awesome! C: Don't make me spank you. M: Is that supposed to be a threat. Alex didn't spank me either, another thing I really liked back in college. What I really loved was slaps on my clit when I was close, another thing I did to myself when home alone and using my toys on my two holes. C: Oh, Mom, to have only known this earlier. Wanting to text nasty... to keep him hard and hopefully get him wanting me to ride him, I asked blunt naughty questions. M: Why, would you bend me over the kitchen table and slam that sausage in my asshole? M: Or put me over your knee and spank my bare bottom for being such a bad Mommy-slut and not offering my cock sucking mouth, burning hot cunt and tight asshole for my son to deposit his sweet cum inside? C: Holy shit, Mom. I would love to hear those words actually coming out of your mouth. M: And I'd love that cock of yours slamming in my shit hole as you fucked me so hard I declared to the entire world my son was a dirty Mother-fucker. C: Ride me, slut, but keep texting me. The words I had been dying to hear... or read. I quickly obeyed, moving my one hand on the top of my husband's seat, while keeping my phone in the other. I slowly began moving up and down, glancing up to see the rain was coming down even harder now. There was no way Alex would be paying attention at all to what was happening directly behind him. C: Nice and slow, Mom. M: God, I just want you to bend me over and take control of me right here! C: You're such a slut, Mom. M: Your slut, baby. C: Forever!!! Reading that word. One simple word. I realized that this could be more than a 3 day backseat stand... it could be so much more. M: You want to fuck Mommy for more than just during this road trip? C: Mom, I own you now. I plan to have you come visit often and shoot so many loads of cum in you that you will be cum-bloated. M: No such thing as too much cum. C: Is that a challenge? M: A fact! C: You have experience with this? M: More fantasy than reality. C: So what is your fantasy? I pondered this. I could probably list a dozen. I want to be with a woman. I want to be double penetrated by two cocks. I would like to be the centerpiece of a gangbang or a train. M: I have quite a few. M: U? C: Tell me. I continued slowly riding my son, as I listed just some of my fantasies. M: I would like to be with a woman. M: I would like to be double penetrated. M: I would like to be gangbanged. M: I would like to go to a glory hole and suck cock after cock. M: I would like to be triple-penetrated. M: I would like to be with a she-male. C: A she-male. M: A cock and tits... that is the best of both worlds. C: LOL. My pussy was on fire as I listed my many naughty fantasies to my son. I wanted to come... no, I needed to come. M: Do you want to watch Mommy eat cunt? M: Get double penetrated? M: Gangbanged? M: Fisted? M: Have a cum bath? C: Oh God, so hot. He grabbed my hips and began pumping furiously into my wanton cunt. Knowing he was close to coming, I decided to keep texting nasty. M: Do you want to fuck Mommy's ass? M: Pound the living shit out of Mommy. M: Ream her butt. M: Cleanse my asshole with your full load of cum. I felt his cum erupt inside me as my own orgasm built. He pulled me back onto his cock and held me there, preventing my orgasm from erupting. C: No coming for you yet, Mommy. I was completely frustrated. I was so close and desperate to come. M: Please!!! C: No! Mommy-pets only come when they get permission. M: I'll do anything. C: Anything??? M: Mommy is your complete obedient cum slut, baby. C: Anything has a pretty wide scope. M: Yes, baby it does. C: You'd eat cunt for me? M: YES!!! C: You'd fuck me and a buddy simultaneously? The idea of fucking him and his good friend Calvin immediately popped into my head. Somehow years of fantasies, of reading online literotica and watching porn wasn't enough. I wanted to live out my many slutty fantasies... I wanted to be the star of my own porno. M: YES, please!!!!!!!!!!!!!!!!!!!!!!! C: What about coming to my frat house, if I join one, and being a cum bucket for the entire fraternity? M: OH MY GOD!!! I might come just by sitting here. M: Does my son want me to be gangbanged? C: I'm asking the questions here. But yes, helping make your fantasies come true would be both a major turn-on and gratifying as well. So desperate to come... so desperate to impress him... so in love with him as both a son and a lover... I used a word that would forever change our relationship. M: I will obey whatever you order me to do, Master. C: MASTER!!! I like that. M: I mean it, Master. I will obey you without hesitation or limitations. C: What about Dad? Would you scream 'Your son is reaming my asshole?' Aye! The rub. I was so overwhelmed with lust that I briefly forgot I was not only married, but my loving husband was inches away. Guilt immediately came back, which was ironic considering all I had already done. M:??? M: I love your father. M: And I love you. C: I love him too. C: But, this is real. Real.... Was it? It was raw. It was intense. It was taboo. But... was I willing to end my marriage to be with my son? Reality came crashing in hard. As I pondered this reality, Alex spoke for the first time in a long time, "Pulling over in three miles. I need to pee, we need gas and we should likely have lunch." With my orgasm suppressed by a sudden guilt, I agreed, "I could pee and eat too." Cory added, "Me three." I remained on his cock until Alex was pulling off the highway. I slowly got off his cock and felt his cum and my wetness leak out of me and down my leg. As I smelled my sex, strong and undeniable, I was thankful for my husband's anosmia... his inability to perceive odor (which was caused by chronic meningitis as a teenager). I moved my thong back over my leaking pussy and moved to my son's right leg. He texted me: C: We will continue this conversation later. C: PS: I plan to plug that ass sometime today. We didn't say anything, as we both contemplated the one flaw with this intense sex... my husband and his dad. I love Alex. He is a good man. A caring husband and a great provider. Yet, he had never really been able to understand my sexual desires or even attempt to fulfill them. For years I had just accepted that this was the way it was. Yet, yesterday's raw carnal sex had awakened the sleeping slut in me, and I had no intention of putting it back to slumber. I decided to text back, willing to risk everything for more of that sexual intensity, my cunt and ass overruling my moral code... or what was left of it. M: You better. My asshole is tingling with anticipation for that big thick cock of yours. C: You better find some lube. I'm reaming that asshole first chance I get. As the car pulled into a rather large parking lot with a few restaurants, gas stations and more, I pondered if we could somehow slip away to a bathroom that was inconspicuous. And where the hell would I get lube? As soon as the car stopped, I got out. I looked around not for a bathroom, even though I had to pee, not for a restaurant, even though I was hungry, but for a place that would sell anal lube... which seemed unlikely. Alex said, "Let's eat first." "Well, let's go to the washroom first," I countered. "Okay," he nodded. "Then let's meet at the family restaurant. I need to have some real food." "Sounds good," I nodded. I headed to the bathroom. I was sitting on the stall peeing when I got a text. C: I just googled anal lube alternatives and apparently coconut oil is one that works well. I figured that was slightly easier to find, but not a lot. I quipped back: M: Shoot, I just used the last of it this morning. C: I'm going on the prowl for coconut oil or lube. M: Happy hunting! M: Master! I finished peeing and went to meet my husband. He asked, "Where is Cory?" "I thought he was with you," I lied. "I should text him," he said. "Oh, let him be. He is capable of fending for himself," I said. "True enough," he nodded. "Plus, that will give us some alone time." "I'm not sucking you off in the restaurant," I quipped, before adding, "although if you can find a discreet location I wouldn't mind a quickie." "You are suddenly insatiable," he said, shaking his head. "That sounds like a great name for a porn movie," I joked, as he found an open table. We had lunch and chatted about our brief road trip while we waited for our condo to be ready. We were just finishing up, when Cory texted: C: Circle C family bathroom now! "Is it Cory?" Alex asked. "Yes," I nodded. "He needs some money. Apparently where he is eating doesn't take credit cards." "Oh, I can go and help him," Alex said. "No, no," I said, trying not to look too eager. "You pay the bill here, get some snacks for the drive... I want some licorice, and fuel up the vehicle." "Yes, drill sergeant," he joked, always teasing me about my planned itinerary. "You better be ready to be a full time drill sergeant once we drop Cory off tomorrow," I quipped back, before I kissed him and walked away. I texted: M: On my way, Master. C: Hurry up slut, C: Time for your butt! I laughed at his terrible rhyme and tried my own as I saw the Circle C a couple of buildings down. M: You're no Eminem. M: But you can have my back end. C: Okay, that was better, LOL C: Now hurry up!!! I walked double fast, almost running... knowing time was of the essence. Reaching the bathroom, it was locked. I knocked. The door opened and I quickly went inside before it closed again. "Bend over the sink," Cory ordered, taking control quickly. "Yes, Master," I purred, turned on by both his strong persona and what we were apparently about to do. Once I was bent over, I saw lube in his hand. I asked, "You found lube?" "Believe it or not, yes," he nodded, as he tugged my thong down, and poured some on his cock and then down my ass cheeks. A chill of adrenaline coursed through me at the reality I was about to be ass fucked. I had fantasized about it for years, tried to replicate it for years, yet nothing beats the real thing. I felt his cock rub up and down my ass cheeks and then felt his cock teasing my asshole. I moaned, "Just slide it in, baby. My ass was made for your cock." He laughed, "Who would have thought I would ever hear those words from you two days ago?" "Yesterday morning evennnnnn," I pointed out, as his cock broke the invisible barrier that prevented such outside violations. "So tight," he groaned, as his cock moved inside me, slow like a turtle. Backseat Mommy: Ass Fucked "So big," I groaned back, loving the way his cock widened my asshole. "Shit, I can't believe my wholesome Mom loves it in the ass," he said, clearly in as much awe at the moment as I was. "I can't believe my good boy is so willingly sodomizing his mother in a public washroom," I quipped back. He didn't respond, as his hands held onto my hips, and he kept going deeper into my back door. I, on the other hand, kept talking, loving the opportunity to talk after having to be so quiet in the vehicle, "Oh yes, baby, I want that entire cock of yours buried in Mommy's ass." "Almost there," he declared, as the never ending slow penetration continued. "I feel like you're impaling me," I whimpered, a pleasure and pain mixture coursing through me. I had always loved the pleasure-pain oxymoron. Through pain came more intense pleasure. "All in," he announced a moment later. A chill went up my spine at taking the entire cock in my ass. I asked naughtily, "Are you going to sit there and celebrate, or are you going to fuck Mommy's ass?" "Beg, Mommy-slut," he demanded, not yet moving. "Oh, baby, fuck Mommy's asshole. It hasn't been fucked by a real cock in over twenty years," I begged and revealed. "Time to make up for lost time," he declared, as he began to slowly fuck me. "Oh yes, baby, it feels so good," I moaned, the pleasure growing quickly. "You love it in your ass, don't you?" he said, after a minute of slow fucking. "I love your cock in any of my holes," I responded. "Information that would have been good to know my whole senior year," he joked. "I didn't know you were this well-hung," I quipped. "So I should have just bent you over the kitchen table and fucked you senseless?" he questioned, as he started to go faster. "Oh, if only you had a time machine to go back in time and do just that," I purred, the idea so fucking hot. "We definitely need to make up for lost time," he said. "Then fuck me harder," I moaned, my long denied orgasm building again. "I don't know," he teased, continuing his steady pace. "Please Master," I whined, "Mommy needs her shit hole destroyed by your huge missile." Suddenly he thrusted hard, making me scream, as he reached new depths inside me. "You like that?" he asked, buried deep in me. "I don't want this to ever end," I answered, before adding, "now do it again." Then my phone rang. "Shit, it's your father," I sighed. "Interesting choice of words," he laughed, as he gave me another hard deep thrust. "Fuck, baby," I yelped, as I grabbed the phone. "Answer it," he ordered. "Try not to make me scream," I said. "No promises," he answered, as he resumed fucking me. "Hey, baby," I answered. "Where are you?" he asked. "In the bathroom," I answered. "Almost done?" he asked. "I may be a few minutes," I answered. "Oh, okay. Did you find Cory?" he asked. "He found me," I replied. "Well, I'm ready whenever you are," he said. "Okay, I'll be out there soon," I moaned, as Cory started fucking me faster. "You okay?" he asked. "Upset stomach," I answered. "Oh, okay," he said, clearly uncomfortable. "Take your time." "Oh God!" I yelped, as Cory slammed into me again. "I better let you go," Alex said. "K," I whimpered, hanging up. "You brat." "Slut." "Mother fucker." "Ass taking cum slut." "Drill my ass," I demanded, the name calling only enhancing my growing desire to cum. He pounded me for a few more hard thrusts and then suddenly pulled out. "What are you doing?" I whined, my orgasm near apocalyptic explosion. "Just making sure your ass is well gaped for the car," he revealed, as he put his cock away. "You can't be serious?" I questioned, horny as hell. "Oh yes, you're my backseat Mommy," he smiled, as he slapped my ass hard. "You fucking bastard," I snapped, as I stood up, and pulled up my thong as his phone rang. "Hi, Dad," he greeted, pointing to his cock. I glared at him, but dropped to my knees and fished out his cock. "Yeah, I'm just finishing up here," Cory said, as I took his cock that seconds earlier was buried deep in my asshole, into my mouth. "Yeah, I'm with Mom," he said. "She's just finishing eating a hot dog." My eyes went wide as I bobbed on his cock, the taste of my back door on his dick tangy. "I know, she has quite the appetite," Cory agreed, before adding, "I don't know how she takes it all in her tiny frame." I could barely keep from laughing at the naughty innuendo he was saying to his Dad, who would be oblivious to it completely. "Okay, okay," he said, as he grabbed my head and began fucking my face. "I'll tell her to hurry up and swallow it all." A few seconds later, I felt his cum slide down my throat. I swallowed it all as he kept pumping his dick in my mouth. Once done, he pulled out and said, "We should probably get back." "That load was supposed to be for my ass," I pointed out, still on my knees. "I didn't want my cum leaking out of your gaping ass and onto me," he said. "Asshole," I quipped, as I stood up. He smirked, "Ass, asshole, shithole, it's all the same." "I still haven't come," I pointed out. "Be a good, obedient Mommy-slut and I may let you later," he said, as he walked out of the washroom. I sighed and followed as I said, "I can't believe what you said to your father." "What? I was serious. I am amazed how you can take a whole sausage," he smirked. Alex was leaning outside the car. "Ready?" Alex asked. I nodded as I followed my son in the back seat. For the next hour, nothing happened, which was both surprising and stressful. A lot of questions popped into my head: Did he plan to fuck me again in the car? Did he plan to fuck me in the ass in the car? Was he going to let me finally have a fucking orgasm? Why was he ignoring me? In the end, my insecurities hit me as did my burning libido. I texted him: M: Are you going to fuck me or what? He didn't respond, instead asking Alex, "Do you know where we plan to stay for the night?" "Are you sick of your mother sitting on your lap already?" I asked, rubbing my ass on his cock. "No," he said, "Just curious." Alex said, "Well, if we push hard for three hours we will hit Edestoon." "That would be a great place to stop for the night," Cory said. "Think you two can last three more hours back there?" Alex asked. "Oh, I think we will be okay," I said, as I moved my hand under myself and to my son's hard cock. "Yeah," Cory agreed, "I'm so used to this now it's like Mom is one of my appendages." I couldn't help but laugh. Alex did too. "I'm really sorry to put you two in such a tight place." Cory quipped, as he moved his hand under me and to my ass, "Oh, I've been in a tighter place." My face burned at the naughty, blunt innuendo that my son had just said. As his finger teased my ass, he texted me: C: So you want me to fuck you in the ass right here, right now? I didn't hesitate, my desire to come overriding everything else. M: Yes, Master. Fill my asshole with that big dick of yours. C: Think you can sit on it entirely? M: Yes, or die trying!!! C: Slut! M: Mother fucker! C: Incestuous criminal. M: You're my partner in crime. I saw him grab the lube and hand it to me. He wanted me to lube his cock and my ass. Somehow this only made it hotter and nastier. I fished out his already hard cock. I poured a lot of lube in my hand and stroked his glorious cock slowly, loving the feeling of his hard meat in my hand. I then leaned forward, leaning against the seat, which caused my husband to turn to look at me. "Are you alright?" he asked. "Just changing positions," I truthfully answered, as I simultaneously rubbed anal lube all around my rosebud. "We can take a break whenever you want," he said. "No, no," I said, as I slid a finger slightly inside my ass. "It's such a miserable day. We may as well just keep chugging along." "Yeah, it's really raining cats and dogs," he nodded. "Well, you focus on the road," I suggested, as I positioned my son's cock straight up and slowly lowered myself on it. "And we will just keep ourselves entertained," I added, giving my own naughty innuendo. "Will do," he nodded, as I sat directly over my son's flagpole. Cory's cockhead was at my eager back door and I ever so slowly sodomized myself on the majestic magic cock. The earlier ass fucking in the bathroom and the excessive lube made his dick slide inside me rather easily and with only a mild discomfort. That said, it was countered by the euphoria of having a dick back in me and the voyeuristic thrill of willingly sodomizing myself with my husband literally inches away. I was about two thirds down, taking my time as I prepared myself for how deep he would be in me in this position when Alex swerved and I collapsed entirely on his cock. "Oh fuck!" I screamed, as I impaled myself on my son's sword, a sudden intense pain as his cock reached seemingly impossible depths. "You okay?" Alex asked, slowing down. "Yes," I said, trying to compose myself. "I just got banged up on that swerve." Cory quipped, "Yeah, you slammed into me good." "Sorry," Alex apologized, "there was a deer on the side of the road." "It's okay," I said, the words having different meanings to each man. "I just need some time to recover." "Okay," Alex said. As I sat on my son's cock, I just tried to get used to the simmering pain that coursed through me with the sudden impaling. Cory texted: C: Just relax. We're in it for the long haul. M: Okay! Your cock pretty much impaled me. C: It would be a great way to die! M: If I die before I come it will be the worst way to die ever. C: LOL!!! C: I am preparing a BIG surprise for you tonight!!! M: What??? C: It's a surprise!!! M: I hate surprises! C: I think you have enjoyed the last two days of surprises. M: But I didn't know in advance I had a surprise coming. C: Now sit and be a good Mommy-pet!!! M: Yes, Master! And I obeyed. I just sat with my son's big cock lodged deep up my asshole. As the miles rolled by, the pain eventually faded away and I wanted to start bouncing on his pogo stick. Yet, I just sat there. I waited for orders. Alex asked, "A truck stop in 5 miles. Do you guys want to stop?" "No!" I said, a little bit too emphatically. "Okay, okay," Alex laughed, "I just thought you may need to stretch." "I'm all stretched now," I replied, and then realized that would make no sense to Alex. "Okay," he said. C: You nasty slut! You really want a good fucking, don't you!!! M: I want you to ream my asshole until I come and you erupt a load in it. C: Right here? C: Right now? I knew I should wait until we were somehow alone... maybe again tonight. Yet, I needed it now. This long withheld orgasm was begging to be released. M: I'm your slut! C: That may be true... but that isn't an answer to the question. M: Yes, I want you to fuck my ass right here, right now!!! M: Ream my ass until you deposit your seed deep in my rectum. Suddenly he bucked up, his cock somehow reaching new depths in me. "Oh, God!" I gasped, a new pleasure and pain instantly coursing through me. "What?" Alex asked. "I just saw a dead dog on the side of the road," I lied, even as my head spun. "I didn't see anything," Alex said, looking in his mirror. "It's so sad," I said, as I began slowly riding my son's cock. "It was there," Cory said. "Okay," Alex said. "I better focus on this road." "Please do," I said, before biting my lips to keep my moans from escaping. I can't explain it, as I am sure I'm in the minority in regards to it, but I feel greater pleasure and have bigger orgasms from anal sex... although for the past twenty plus years it had been only with sex toys. The pleasure of a real cock in my butt was incredibly stimulating and created anticipation of utopian euphoria. For a few minutes I slowly rode his cock, getting used to my son's huge cock in me... again the pain fading as a pleasure built. Then, wanting to really get fucked, I began riding him faster. I wanted to bounce up and down on his cock, take it as deep as possible inside my asshole, but that would make too much noise, so I focused on just going faster. Yet, I couldn't get any real rhythm going and was getting frustrated. Cory seemed to notice my frustration as he texted: C: Up and to the side so I can plow your back door. I obeyed, leaning to my side so my head was between the two seats. Cory repositioned himself, leaning too, and slid his cock in me. I bit my lip so I wouldn't moan. I moved my hands to the side of the passenger seat for leverage, and just allowed my son to fuck my ass. He fucked me fast, all the while not slamming into me and making sounds that would get us caught. Although I was enjoying the fucking, I wanted it rougher, harder and deeper. Alex asked, looking at me, "Is that comfortable?" I was speaking more to Cory as I answered, "It's not perfect, but the best for the moment." "I think I'm going to pull over at the next truck stop. I need to pee," Alex said. "Okay," I nodded, worried I would again be left without an orgasm. Cory kept fucking me, although not hard enough to get me off, and in the position I was in I couldn't get my hand to my fevered twat. "Here's a truck stop," Alex announced, a couple minutes later. Frustrated, I moved back and sat entirely on Cory's dick. I lifted my ass up a bit, trying to tell Cory wordlessly to fuck me. He caught on and resumed fucking me even as we slowed down. I was frantically rubbing myself, my orgasm imminent and yet refusing to erupt. I kept getting ass fucked even as my husband came to a stop, making me fall back onto my son's sword. "I gotta pee," Alex said, hurrying out of the car. "Pound my shithole," I demanded, the moment Alex was out of sight. "Ride me, slut," he ordered. And I began bouncing. Finally able to really get fucked. I rode his cock furiously, not worried about getting caught, only focused on coming. "Come, my nasty ass slut," Cory demanded, "Come now, like the dirty cum slut you are." "Oh God, yes," I moaned loudly, my orgasm finally about to break the invisible barrier. "I'm about to come in your shit hole," Cory groaned. "Oh yes, come in Mommy's dirty asshole," I moaned, bouncing recklessly on his cock. "Aaaah," he groaned, a couple bounces later. As soon as I felt his load explode inside me, my own cum exploded out of me. "You mother fucker," I screamed, as the bubble burst and intense pleasure cascaded through me, and flooded out of me. "Yes, come my slut," he groaned, as his cum continued to fill my ass. Even though I was still coming, I knew our time was short and I opened the door, getting out and quickly pulling my thong up even as I felt cum leak out of my ass. Looking up I saw a couple teen boys as well as an older woman staring at me. Suddenly feeling ashamed, I went directly to the bathroom, actually walking into my husband. "You okay?" he asked. "You look all flustered." "I really need to pee," I answered, continuing past him and to the washroom. I went directly to a stall, pulled down my panties and did indeed urinate. I also allowed some of my son's cum to drip out of my gaping ass. I couldn't believe I had fucked my son again in the car... unable to resist the temptation. It was like his cock was the forbidden fruit and I unable to not eat it whole. As I cleaned two bottom orifices, Cory texted me: C: That was amazing! M: I can't believe we just did that! M: People watched! C: Are you ready for more? M: You can't be serious??? C: OH, I need a rest too. But click on this link. Tonight we are going to make another of your fantasies true. I clicked on the link and gasped. It was a Craigslist ad. Horny submissive MILF slut looking to be DP'd. Submissive three hole cum slut wants to make her double penetration fantasy come true. Her young Master is looking for one or two men with big cocks who are willing to DP her or even make her AIR TIGHT.

I couldn't believe Corey would do this. I also couldn't believe the rush that went up my spine at the possibility of getting double penetrated and just used like a cheap slut. As I finally stood up, unsure how to deal with this new situation, I got another text. C: I got a dozen responses so far. C; Would you like to try a black cock? C: Ten inches! C: And thick! Oh my God!!! I could finish two fantasies at once. I had always wanted to fuck a black man. I often read race play stories online, and my favourite porn to watch was interracial. C: Here is his picture!!! I clicked on it and my mouth instantly watered. Fuck! Somehow fucking my son seemed less like cheating... I know absurd, but true. This would definitely be cheating. As I contemplated the big black cock, I went and washed up and looked at myself in the mirror. What was I becoming? And why couldn't I resist being such a slut? Yet, even though I knew I shouldn't... I texted my son: M: BOOK HIM!!! The End... for now. Coming next: Backseat Mommy: Gangbang Possibly followed by: Farewell Facial Lesbian Adventure Parents' Weekend
