This happened about a month ago. My friend and I were talking about porn, and stuff, and the topic got onto masturbation. So we decided to look up some porn. When we were about 15 minutes into it both of us had huge boners!
He asked how big I was and I am 5 and a half inches hard. I asked him and he said 4 and a half inches, he's older than me by a couple of months and he was smaller than me. He said he was going to go to my bathroom and jack off, so I decided to stay in my room and jack off on my bed.
Well, I had jacked off three times that day so it was taking me a while to cum again, he was done before me. My friend came back in the room and said 'Holy shit man! that looks bigger than 5 and a half inches.' I was like 'Yeah, I use lube so it kinda soaks it up making it look bigger. Plus, I am really horny, because I am imagining screwing my girlfriend!'
After about 30 minutes (yes I know a long time) I started to cum. I shot my cum farther than I ever had, it hit my stomach, chest, and my chin. My friend said 'Damn....Was that a good one?' then I said 'Oh, hell yes!'
Then we talked about porn that whole night, and jacked off a few more times. That was the funniest night I have ever had.
