I hesitate to tell this story because I’m still processing it myself. This happened about three years ago. My wife (26F) and I (32M) had just been married about two months at the time and the honeymoon phase was still in the air. We were crazy about each other, for now.
We had got the sexual chemistry down to a science by this point in our relationship. It was always good, and pretty predictable. I knew eventually we would have to spice things up down the road, but for right now we were both happy. I always knew, or thought, I could make her orgasm, and it seemed to be reliably every time, at about the same point in the session. I would do everything I knew she liked. I would start with slow tongue strokes on her clitoris, and then move into missionary for a few minutes, and finally I would flip her onto her belly and into something like doggy, and that’s about when I would come, somewhat reliably, every time. She always reassured me she was content with that arrangement.
One day, she began to seem different. I couldn’t put my finger on it at first, she was just not herself. Her libido was just gone, and every time I tried to initiate anything my efforts were met with a dismissive wave or half-assed excuse. I tried to broach the topic sensitively to not sound accusatory but I really just wanted to know if it was something I said, or if there was something she wanted. Every attempt, met with dismissal, and sometimes even a subject change. I was becoming sexually frustrated, but I was keeping that to myself so as to not worsen my already low chances at scoring sometime in the near future. My self esteem was starting to take a hit, too. But again, I kept it to myself. Little did I know it was about to be completely destroyed.
I usually get home from work late, but on this particular day I got off early. It was three days before our anniversary. I texted my wife to see about dinner plans considering I was off early, but the text didn’t go through. I thought that was odd but didn’t think much of it again. I made it home before the text delivered to find a strange and very expensive truck in driveway. My neighbors were getting their driveway redone so I assumed my wife let them park there while that happened. No problem. I parked in the street and walked into the house through the front door. As I opened it, I hear what I assume to be porn playing very loud, as my wife often times likes to watch hardcore porn. Maybe now was my chance, if I could catch her while she was horny and touching herself maybe I could finally rekindle that sexual relationship with my wife. I approached the bedroom door from where the loud female voice was yelling with pleasure, opened it slowly so as to not startle her, with blood already beginning to rush to my penis, and found a the most heartbreaking yet erotic thing imaginable. There, lying on her back in our shared bed, was my beautiful wife. The TV was off.
Instead of some absurd porn being the source of those strange female noises, it was her, making sounds I have never heard her make. She was folded into a submissive position with her feet by her head, a shape I didn’t realize her body could make. Both feet were held in this position by the biggest, strongest hand I’ve ever seen. A matching hand was grabbing and pulling her hair. And her beautiful eyes were fixated in a sort of worship at her partner. My eyes went right to the main focal point: a penis that rivaled that from the best porn in the world, and her tight vagina, which was gripping and stretching in ways I had never seen before. Directly below this action was a puddle soaked through the sheets and into the mattress, which I had also never seen from her.
They were so fixated on each other that they didn’t even notice me at first. They continued their rhythmic pleasure motions, the bed creaking, my wife moaning so loudly, and her lover’s carved physique flexing with every thrust deep into her. He was quite sweaty and completely naked except for a gold chain. He was tan, about four inches taller than me, about four inches longer than me, and probably forty pounds heavier of pure muscle. His large balls were swinging back and forth and slapping her anus with each motion.
I was simultaneously devastated by and in awe of the beauty unfolding before me. It was at this point that I noticed that my half erect penis was now fully erect in my pants. I just stood there frozen. I didn’t know what to do with this combination of powerful emotions I had never felt before. I was shocked, I was hurt, I was angry, I felt inferior, and yet I was stimulated. I wanted to run over and stop them, but I also wanted to see what would happen next.
My confused daze was interrupted by a startled yelp from my wife, I guess she noticed me now. Her partner’s head whipped around to see me standing there, a horrified expression on his face and a dumbfounded one on mine. His cock now outside of my wife for the first time, precum dripping off his perfectly shaped head, she immediately sought to remedy the problem. “Ignore him and put it back in! I need to cum more!” she said with a sexual urgency unknown to me. “What?? Are you sure, he’s right there!” he responded to her in disbelief. “He won’t do anything, look at him! He probably likes it anyway! Let him watch you cum deep inside of me.” This last line from her caused a pain deep inside of my chest that I’ve never felt before. Utter disregard for my sovereignty. Utter disrespect. Utter betrayal. And yet, she appeared to know me better than I knew myself. He turned his attention back and cautiously slid back inside my wife, accompanied by a relieved sigh and a smile from her.
They took this opportunity to reposition. With his penis still inside of her, he picked her up and rotated her onto her belly, lifted her pelvis up so that her holes were presented up to him and her face pressed into the bed, and began that beautiful rhythm again. This time, the skin-on-skin slapping sound was louder, and her pussy was singing from his pumping. He was going harder and harder and she encouraged him more and more and more, until finally a climax the likes of which I had never seen: she screamed that she loved him and she gushed so hard that she squirted, adding to the already existing puddle on the mattress. It was at this point that he could no longer retain his semen and he released ounces of it all over her cervix, his deep and gravely voice desperately moaning his reply. As he slowly removed his penis from my wife, her pussy still gripping, holding on as much as it could, she managed to pant out between breaths “your turn baby”, the first time she addressed me at all since I got home.
I was so confused. I’ve never wanted this. I’ve never desired anything like this before, or so I thought, but here I was standing with a full erection as my wife’s lover’s semen dripped from her pussy. I felt like I was supposed to be outraged. But the next thing I knew, my cock was in my hand, smaller than his but just as hard. He sat on the side of the bed watching me, already hard again and stroking his balls. I slid into my wife. It was so warm and gooey. I actually liked it. I looked over to my new rival for approval, and he seemed to really like what he was seeing too, because more precum was already dripping out of him. She gave no indication that she could feel anything at all.
It was at this time that my new friend became seriously interested in me. He asked if I had ever tasted cock. I said I hadn’t. He asked if I’d like to. What the hell, we’ve already come this far. He stood on the bed, straddling over my wife, and as I got my sloppy seconds, he put it in my mouth. Indeed I had never tasted a penis before, and his tasted like my wife’s pussy, which was hot. I Tasted many parts of him that day: his cock, his balls, his abs, his chest, all under the approving eye of my wife. I let him gag me with his head while he firmly but not dangerously grabbed my neck, and then he masturbated into my mouth. His semen tasted potent. All of this got my wife worked up again and she enthusiastically let me finish inside of her along side his load.
He was already stroking again priming his balls for a third load while I was still exhausted from my first. My wife looked at me with a smirk and suggested, “better eat that cum out of me before I get pregnant”. I ate both loads enthusiastically, digging into her with my tongue to get every last drop. We needed to let our balls recharge so we took an intermission here. Part two will have to be for another time.
This night changed my life. This new open relationship has certainly spiced up our sex life, and despite the betrayal, I’m grateful to my wife for opening me up to this experience.
