It all started in a nightclub five months ago. I had gone out with a group of girlfriends, while my boyfriend stayed home—just to clarify, I’ve been with him for four years. The night was going really well; we were having fun without overdoing it. Two of my friends were single while the others were in relationships, so I mostly stuck with the ones who weren't looking to meet anyone. But when I stepped out for a cigarette, a guy (a rather cute one, actually) came up and asked for a light. I gave him one, and he started hitting on me. He paid me a few compliments and suggested we get a drink. I turned him down, explaining my relationship status, and went back inside. The night went on, and I saw that my single friends had found guys to spend the rest of the evening with—friends of the guy I’d given the light to. When it was time to leave, our groups merged. The cute guy asked me for a light again and started chatting with me. A bit tipsy, I found myself drawn into an increasingly risqué conversation with him; I didn't really realize what I was doing. We took the train home, and since I lived the furthest away, I was the only one getting off at the last stop. Because we were deep in a very steamy conversation, the handsome guy "forgot" to get off at his stop—though, looking back, I know he did it on purpose. I suggested he come sleep at my place—I was living in a small studio apartment for my studies—but I made it clear that nothing would happen. Once we got there, we were both still under the influence of alcohol, so we waited a little while before going to bed. Naturally, there was no sofa in my studio apartment, so we sat on my bed. He went to the bathroom, and I waited for him on the bed. When he came out, he was completely naked. He had a huge cock—it was so arousing. I was shocked but suddenly incredibly turned on. He didn't say a word; he just walked over and placed his hand on my cheek. I was sitting and he was standing; I realized very quickly what he wanted. I acted purely on impulse. I opened my mouth and started sucking him off. He tasted so good, but I couldn't take it all the way in—it was too big. He placed both hands on my head, pressing down a little harder each time. I finally managed to swallow his huge cock whole—I still don't know how that was even possible. After a good ten minutes of oral sex, he pulled out. I immediately lifted my skirt and took off my thong. My pussy was so wet that he slid right in on the first thrust. He fucked me like a whore. I was moaning so loudly. He took me in every position all night long. Of course, we didn't use a condom. I don't remember exactly, but I think he came inside me at least three times. He was a sex machine—I’d never seen anything like it. I came twice; my legs were shaking. I was in heaven. The next day, he left with a kiss and told me he wasn't done with me yet. Since then, I’ve been seeing him at least once a week. He still fucks me like a whore and buys me sexy lingerie to make him even harder. I haven't left my boyfriend, but I hardly get any pleasure with him anymore. And to top it all off, since we never use protection, I’m sure he’ll manage to get me pregnant with those massive loads of his. Honestly, I’m completely torn between loving being a slut and staying with the man who loves me.
