So my boyfriend and I went to a party Saturday night and we both got drunk off our asses. Well it gets us horny, so we find a room and I start to suck his cock. Usually it takes him a few minutes to cum, but I swear it took him 10 minutes this time!!
By the time he finally came my jaw hurt, and my hand even felt a little numb. Ugh as much as I love him and his huge dick, when I have to suck it that long it's loses a bit of it's appeal...

Any other women have this "problem" with their guys?
Do they ever do it on purpose?
