Mark got up and dropped his jeans on the floor, and pulled off his t-shirt on the way to the bedroom. As I followed him, my head was spinning. I just gave a guy a blow job, and now I was following him so he could fuck me. After we entered the bedroom, Mark lay down on his back. Once again, everything was up to me. I got out a condom, and rolled it over his cock. Then I opened the lube, and put a generous amount on his cock, and and a coated two fingers and worked them into my hole. As I said, his cock was 7" cut, and on the thinner side, which was a little of a relief for my first time.
After everything was well lubricated, I straddled myself facing him. Again, Mark left everything up to me, so I grabbed his cock and placed it at my hole. I knew from playing with dildos that if I pushed out, then his cock would slide in easier. It took a few tries, but then I felt the head push in. I stopped there to get used to the feeling. Even with the condom on, a real cock felt very different from a dildo. I felt my hole stretch around his member. It burned a little, but not much pain otherwise. When I was ready, I slowly slid down until he was halfway inside of me. Then a rush of thoughts went through my head. Another person was actually inside of me! I thought back to the girls I had sex with and wondered if they felt the same way, how it felt for them. Mark brought me back to reality when he asked if I was OK. I said I was and started slowly riding him. I can't say this first time was really pleasurable, but more like I accomplished something that I always was curious about.
After riding him a short time, Mark was satisfied that I had done enough and asked me if I wanted to change positions. So I pulled off him, and got off the bed. Mark told me to lie on my back. He put a pillow under my ass, added a little more lube, and climbed between my legs. I instinctively pulled my knees up to my chest. He rubbed his cock around my hole, which felt great! Then he slowly pushed into me. He entered easily this time, and started a slow rhythm. This felt much better than me on top, and started to feel really good. Marks said "Someone's having a good time". I looked down, and my cock was as hard as it has ever been. Then I though, yes, I am having a great time! Mark was really gentle and slowly fucked me. After a few minutes he told me he was getting close and what would I like. I told him this was good, and after a short time, I could feel his cock start to spasm as he shot his load into the condom. He lay on top of me for a minute as his cock drained, and I really liked the contact. I never felt physically attracted to guys, I was mainly interested in cock, but I had to admit that this felt good.
After a minute or two, he pulled out, and asked if I wanted to cum. I told him yes, so he took my cock into his mouth. Mine is about 6", and thicker than average. But Mark was an expert cock sucker, and was deep throating me in no time. I was in heaven. No woman had ever given me such an expert blow job. I guess it's true that guys give the best ones. After not too long my cock swelled even more, and I came as hard as I ever have. Mark swallowed every drop until I was completely drained.
After a short while, Mark asked me if I wanted a drink. I told him no, that I needed to get home. We said our goodbyes, and made arrangements to meet the next week. On the drive home I thought about all the things that I did, and that I wanted to do much more. I was looking forward to continuing this journey.
