I did something to my best friend. It was the summer between highschool and college. We got really close, like brothers. We were going to dif colleges, so we wanted to spend more time bonding. Well, personal boundaries disolved. We'd both spend time nude. He knew I liked cock. He was HUNG! He was about 6"x6" soft. Enormous hard, closer to 10"x6". He was really chill about it too, never bragged about it.
One day, he asks me to blow him to see if he likes it. I tried because huge cocks excite me. However, he couldn't get up, and I wasn't very enthused. It felt weird playing with my friend. We never tried again.
I'm pretty big my self (8" on a good day). Once at a party that summer, some girls saw that I had a big one. (I had a noticable semihardon bulging in my tight jeans; I was hoping to attract a certain guy's attention) I wasn't very interest in the ladies. I normally like guys, only the occasional girl. I want going to let their horniness go to waste. I told them that my friend had a bigger one. They wouldn't believe me. I introduced them to him and we all went back to my place (he was still living with his parents; I was kicked out on my 18th birthday).
The three of them fucked (aren't I a great friend? He eventually repaid the favor that summer with a paid escort... but that's another story.) Aftr the act, He was tired, and one of the girls was still horny. So, I had sloppy seconds. She managed to get me up, she was more attractive sweaty then perfumed. She was still tight considering how much my friend had just stretched her out.
Being "gay" I have female friends who are comfortable with nudity around me. Some have seen my penis soft, but it's not impressive. Nothing ever happens. In my experience, sex only happens when ppl go looking for it, not spontaneously at the sight of any nudity.
