First and only

My girlfriends son came to visit while on break from his 1st year in college. He was a thin, short and alittle on the feminine side. One night my gf was working and shift so I had a few drinks and watch a couple movies. Her son came rolling in and sat down. I wanted to start s conversation so moment wasnt so weird. So I asked him if he had a girlfriend etc. He said no he doesn't date. I asked why. He said hes embarrassed because he had a small dick. I thought he was joking so I said yeah whatever. He pulled it out and yeah he was on the small side. He was semi hard and he gave it a few tugs and he was hard but still very small. He took a couple steps towards me and asks me to help him get off. For some reason my hand went dighf from his little cock. I gave it a few jerks and pulled back. He gets on his knees and pulls my cock out and it went straight to his mouth. I could tell he want used to sucking dick and he was horrible at it. I finally told him to lay on his stomach . I went to do anal and he says "be gentle and go slow. Ive never done this before" it took acouple tries but when the head finally popped in, feeling him tense up and moan in pain turned me on and full hard. I could only go 1/4 of the way in but it felt so tight as I was stretching his little ass out. I came very quickly. He ran to the bathroom ans I went to my bedroom and passed out
