Wife and I were at Halloween party and she was having a great time. She was dressed as Wonder Woman and went as Jason from Halloween. We were both getting into conversations with others and eventually she thought found me but it was another man in an identical costume. Telling him she was horny so he asked her if she wanted to find a private room. She was shocked but excited so she said yes. He took her hand and found a bedroom and immediately threw her on the bed. He pulled her costume off and turned her around so he could fuck her from behind. She was enjoying be handled and let out a yelp as he pushed his cock in. Immediately she felt something was different but also SO good. She started thrusting back and could hear he was already getting heated up. When she could tell he was getting close, she reminded him thinking it was me, that she wasn’t on the pill so to pull out unless I wanted to get her pregnant. he started fucking her harder; this got her even more excited. Just as he was about to explode, she started saying OMG and felt him erupt inside her. She was shaking because it felt so natural and yet risqué at the same time. As he finished emptying inside her she grunted and collapsed on the bed as she turned to look back, she immediately realized that was not my cock. It was much too large and not totally shaved. She was in shock but also SO turned on. She just asked the stranger, still in the mask, what will I tell my husband. He immediately answered, that it was the best fuck you’ve ever had and want to do it again. He asked her for a pen which she got from her bag and he wrote his name and number above her clit, with her slightly resisting, but clearly not enough. He left her and as he walked out he said I’ll give you beautiful children.

She found me after getting dressed again. I told her she looked like she was really drunk. She knew it was not just the alcohol. Knowing she couldn’t tell me there, she just said she probably had enough and hung by my side. Eventually I noticed the other Jason costume and he approached. Commented on the costume and also mentioned Wonder woman was always a fantasy of his. I agreed and mentioned I was tempted to put off coming to the party once I saw her in the costume. Not knowing they had already met, I offered to take a picture of him with her for his fantasy. He eagerly pulled her close. I assumed the alcohol was having an effect as my wife was sheepishly smiling and not keen. So I reminded her to smile. Then he moved her in front of him with them both facing me and put his hands on her bare stomach while looking at the camera over her shoulder. I couldn’t hear what he whispered to her but she went red. I gave him his phone back and he thanked us and told us he hoped to add to them some day. Not sure what he meant by that, I just said, I’m sure you will.

During the ride home I asked why she blushed after the photo. She paused and admitted he said “you have a perfect body to be a mother” I thought that was a little odd but told her he was right. A few curves, awesome tits to feed from, and not too impatient. She had easy pregnancies with our 2 kids. This gave her an opening and asked what I thought if she got pregnant again. I told her I thought she looks sexy when she is pregnant and it makes me want to fuck her seeing a baby bump and swollen tits but I am over 50 and not particularly looking to start over again. Nervously she started explaining what happened. She was all over the place, not really making a lot of sense. Finally she just blurted, I may have gotten pregnant at the party. I heard her but it didn’t process at first. Before I could speak, she kept saying I thought it was you, I told him to pull out. I didn’t know. Finally I asked how she didn’t know. After hearing how he was assertive and did her doggie style, she mentioned how she said “If you don’t pull out I’ll get pregnant” I explained how that isn’t the same as telling him to pull out, that gave him the option. She told me it felt different but assumed it was just because we don’t do doggie style. When I asked what was different, she paused, eventually I got her to admit that he was MUCH larger and when he came, it felt like an explosion inside her. She repeated how there is no chance she isn’t pregnant as she is ovulating and because of how much she felt erupt inside her. I told her to show me. She wasn’t sure she should. Reluctantly she turned on the light and lifted her ass as she pulled her spandex bottoms down. Her panties were soaked and her thighs were glistening. I don’t know why but I reached to touch her clit. She resisted at first and then allowed me to touch her. She was SO slippery and as I touched her clit she let out a soft moan. I looked at her and asked her if she was still turned on. She shrugged her shoulders and said I don’t know ... like a question. I rephrased it and said You ARE still turned on aren’t you??? She replied with, I don’t want to be ... I only wanted to fuck you and she suggested we stop at a store and get the morning after pill and started apologizing again. Knowing how bad she felt, I grabbed her hand and placed it on my raging hard on. She was confused at first. Then she stopped sobbing. You’re turned on?? She asked. I just answered, I imagined you with a baby bump and seeing how sexually elevated you still are is making me horny. She suggested I pull over. Without question I did. We couldn’t get our clothes off quick enough ... Once I did she started to climb over but the steering wheel made it impossible so I got in the back after she lied down. I started mounting her and I had zero resistance. My cock slide right in. I was so horny but I could tell she was stretched. When I asked if she felt me, she said, A little. I think she was lying even at that. As I was starting to get into it I asked her how it felt when he was fucking her. She said she shouldn’t talk about it but I insisted. In a low voice she admitted she didn’t want it to stop. As she felt something was different, she didn’t care, her body was in heat and when he erupted all she could think about was how full she felt and she didn’t want him to stop. This got me close to Cumming. She was surprised but when I told her she could choose between me Cumming in her or pulling out so she can suck me. She just replied, but I’m ovulating. I replied then you’re already pregnant. At that, she pushed me up and I leaned forward so she could have me fuck her doggie style. I fucked like a man possessed and came quickly and she was bucking her hips which was so erotic also knowing it was in her thoughts of his cock and seed. Once I got off her I looked down and saw my wife’s cum dripping pussy knowing some of it was mine and also realized I just pushed another man’s seed towards my wife’s cervix and womb. When I mentioned that to her, she assured me, don’t worry, he was in much deeper than you when he came, so I don’t think it mattered. It was dark so it wasn’t until then that I noticed his name and number. I was a little annoyed but also turned on that he claimed my wife in so many ways and expected her to contact him. I pointed and asked what she was going to do with that. Immediately she said Wash it off of course, then she added, am I right?? It was clearly a question. She was asking me if she could call him. She was still drunk but not that drunk that she didn’t know what she was doing. What would happen if you didn’t, I asked. I felt a knot in my stomach as I asked her. My wife still lying naked, just having taken my cum and another man’s cum swimming inside her, she got a very optimistic and cheeky look on her face and gave a cryptic answer by saying, I never even saw his face and if I’m not already I’m sure I’d get pregnant. I didn’t reply. The silence was killing her. So, she asked, “Do you want me to keep his number?” Again, she was clearly asking permission, my cock was stiffening again which affected my answer, which was “If his name and number are still on your pussy in the morning, If you then fuck him the only rule is no condoms” My heart was pounding as I said this, her response was to sit up quickly and ask Are you sure?!?! I mean, I might get pregnant, Are you sure?!?! I bent over and gave her clit a kiss. As I pulled away, I noticed how slutty it smelled so I kissed it and gave it a lick. She moaned and told me how much she loved me.
