My First Time Having Sex

I was a junior in college and I had had girlfriends but never had real sex. I loved giving oral to my girlfriends and I believe none ever faked an orgasm, but I could be wrong. My roommate asked me to go out on a double date with him and his girlfriend. We were going to meet in Boston and stay at his girlfriends rented apartment. I was more than happy to go since I had never been to boston. We arrived and I meet his girlfriend and roommate. Her name was Robin and she was about 5 foot and very petite. We hit it off and went out to see Boston. We went to all the tourist sites and stopped for chinese food before heading back. On the way back my roommate became sick and when we got back to the apartment he was in the bathroom for an hour and then went to sleep. I was now alone with his girlfriend and Robin. We talked a little and then his girlfriend went to sleep. Robin and I talked about everything. When it came to sex I told her I was a virgin. She laughed and I told her really I was. She asked if I ever did anything and I told her I had given and received oral. Robin's eyebrow went up and asked if I was any good. I told her yes. Robin laughed and told me every guy said that. I looked at Robin and told her I could give her an orgasm within 5 minutes. Robin told me no way and told me to go into her room. I asked how she wanted to handle this and Robin told me to strip as she started to take off her pants. We were both naked and Robin was very petite. She was no larger than an A cup and had no pubic hair. She was looking at my penis which isn't large at all... about 5 inches. She came over to me and leaned up and kissed me. I kissed back and soon we were frenching. My hands were all over her small ass and I was hard as anything. Robin laid on the bed and opened her legs. She was wet and when I was in between them told me I had five minutes to get her off. I went to town on her pussy and clit and when she told me one minute left I could hear her words quivering. I then Sucked hard on her clit and boom her legs closed on my head and she gasped and moaned and went O god i'm cumming. I finally stopped and when I looked at robin her mouth was still open and her body was having mini convulsions. It took her a minute or two to relax and she told me that was amazing. Robin then told me that was her first time getting an orgasm witha guy. After we cuddled for ten minutes Robin started to suck my nipples and then asked if I really never had sex. I told her I wasn't kidding. Robin started to play with my dick and balls and told me tonight I was going to be a man. She climbed on top of me and positioned herself over my dick. Then very slowly I felt myself going inside. She was very tight and after a few minutes I was in. Robin started to ride me slowly and than faster until she was a wild woman. I told her I was going to cum she quicken the pace and I felt myself erupt. Robin even said she felt me cum. Robin then laid on top of me and gave me a big kiss. When she finally climbed off me a lot of sperm came out of her onto me. Robin laughed and told me I must have been storing up. We cleaned up and fell asleep.
