I pop my nut

My cock felt heavy in my hand, and I could feel the incipient orgasm boiling up. I cup my balls and rapidly fisted my cock to bring myself to orgasm. I was right with the guy and I pumped my cock, shooting my long cum shots all over the screen in front of me. I could just see my cum running down the brunette’s big tits, watching her smear his load all over her big tits, making her thick nipples pop out even more hard and erect.

Then suddenly I almost crapped my pants when there was a sudden knock at the door.

“Who the fuck is it,” I said irritably. I had no idea who would be bold enough to want to interrupt a man in what they knew was a jerk off session. None of the gay guys had ever been this bold. I was even more taken aback when an answering voice came from the other side of the door.

“Hello sir, my name is Lindsey. I'm a graduate student doing sexual relations studies at the university and I was hoping you might answer some questions for me. I can wait a bit if you need to, umm, finish. I felt I had waited long enough, over five minutes when the normal male ejaculatory event occurs in less than three minutes, but I can wait some more if you like.”
