This is my first attempt at this. it is a true story not so eloguently written. I hope you enjoy it.

I have only cheated on my husband once. I admit it was such a turn on I would do it again. Don’t get me wrong, sex with my husband is great and he is a very adventurous lover, but the thrill of doing something forbidden was more than I expected. I was so caught up in the moment that I allowed this man to do things to me I would normally never consider.
I was on a vacation with my family, my husband and three kids. We all went to the hotel swimming pool in the early evening to relax after a day of playing tourist. My husband and kids were playing in the pool while I went to watch them from the hot tub. After a while, it was time for the kids to go to bed and my husband took them back to our room while I was still relaxing in the tub. Shortly after they left, a younger black man got in the hot tub with me and started chatting.
Now I am a plus size woman. I was 36 and had three kids by C-section. I am 5’6 with brown hair and blue eyes. My best features are my 38D tits since the rest of my body was not model quality so I was not prepared to be hit on. This young man was flirting with me and I was really enjoying the attention while I flirted back. The whole time we were talking, he was sliding closer to me until he had his hand on my thigh.
It has always been a secret fantasy of mine to sleep with a black guy. This thought was in the back of my mind the whole time he was sliding closer. It is probably why I did not stop him from rubbing my crotch through my tankini bottoms. Unable to control it, my nipples started getting hard and my pussy started swelling with increased lubrication. I was getting terribly horny, only made worse when he placed my hand on the bulge in his swim trunks.
My husband is averaged size, a little over 6”. I have been with guys of a variety of sizes from smaller to bigger, with the biggest being a little over 7”. This guy had them dwarfed. He was probably 8” and felt thick. I gently stroked his bulge without thinking about what I was doing. I was feeling it pulse in the water and made the decision subconsciously that I would fuck this guy if I had the chance.
He discreetly slipped his hand under my suit and started playing with my bare, shaved pussy. It was everything I could do not to moan and make everyone in the room aware of what was happening. Eventually he pulled his hand away and whispered his room number to me before getting out of the tub and wrapping a towel around him to hide his wood. I was at a decision point and chose to grab a towel and head to his room.
When I got to his room, the door was slightly open. He came out of the bathroom, already naked, and told me he hoped I would come. I couldn’t help but to stare at his naked member, it looked even bigger than it had felt. My pussy ached wanting to know if it would fit. He took me by the hand and sat me down on the bed. I stared at his cock for a second before taking it in my hand and stroking it. Naturally, I proceeded to suck on it as he moaned words of encouragement. As I sucked him, he pulled the top of my tankini off, exposing my breasts to the first man other than my husband in 15 years.
He pushed me back onto the bed and started gently kissing me. My legs spread for him and I grabbed his back to bring him close. He kissed down my body so he could suck on my tits. He was very gentle and soft as he sucked them, sending shocks of sensation down my body to my groin. As he did this, he was pulling my bottoms off, again the first man to see me naked besides my husband since the wedding.
Once my bottoms were off, he kissed down my mutilated tummy until he reached my cleanly shaven pussy. It was electric the first time his tongue squirmed deep inside me. As he licked me, his hands were all over me. They played with my tits and massaged my ass. Eventually his fingers found my asshole. I had never done anal before, I did not think I would like it. He gently worked my anus until, without warning, he popped a finger up me. I gasped in surprise but did not stop him. The way he was working me it felt too good to stop him.
I came once while he was doing this. I was amazed at how good it felt. After I came, he slid back up my body and we were kissing again. I grabbed his cock and aimed it where his tongue just came from. He thrust into me, filling and stretching me like never before. He started thrusting slow, but as my pussy took him in, he was pumping faster. I came a second time, loudly. He felt so good in me, I felt so full. I actually whimpered when he eventually stopped.
He pulled out of my pussy, but he was not done. Spreading my legs a little further, he took his fingers and massaged my asshole again before pushing his cock against it. Again, I did not stop him, though this was not something I had ever done before. He slowly entered my ass, stretching it. He paused occasionally to let me adjust so it wouldn’t hurt too much. After what seemed like eternity, he was all the way in. Once he was in, he slowly started to pump. It was feeling better and better as he was going faster and faster.
I came for a third time in half an hour while he was doing this. I never imagined I would be in this situation. I came after he started cumming, filling my ass with his seed. I was quivering, as I had no energy left in my legs. He pulled out and his cum started leaking out with him. Quietly I got my cloths back on. We kissed and I hurried out the door to my husband and kids. I was extremely horny still, even though I had just had amazing sex.
When I got back to my room, the kids were asleep. My husband was in bed and told me to get changed and lie with him. I quickly pulled off my suit and put on my nightie, trying to think of a good excuse to have a shower first. Not coming up with one I crawled in bed with him and another man’s cum leaking out of my ass. We cuddled and he started playing with my recently fucked pussy.
He whispered to me about how wet I was. I didn’t say anything, just kept kissing him. He rolled on top of me and quietly slipped his cock inside me. We giggled a little, him because we were sneaking around the kids, me because he was the second guy in me that hour and he didn’t know it. He did get me to cum again before he shot his load inside my pussy. I didn’t sleep well that night, feeling cum leak out of me from every orifice and mix in the crack of my ass.
As close as we can tell that was the night we conceived our fourth child. At least I know it was not the affair that got me pregnant. I am currently 8 month pregnant with that child. I have not cheated on my husband since. Tonight, though, we are going to meet one of my husband’s friends who has always fantasized about sex with a pregnant woman. Maybe a situation will come up for me to be alone with him.
