I have done this on a couple occasions.. Lucky I consider myself.. One girl, that wasn't a g/f, who I knew at school.. I was going by to pick her up to take her out.. Knock on the door.. I hear, hey come in.. but it sounded a little weird.. I'm like.. alright whats going on.. Walk in, there she is vibe in hand.. I'm like.. ah shit, I'm sorry, you want me to come back.. She's like no, you can stay... So I pull up a chair, and watch.. I'm simply amazed, she really got into it, and then after a while, she asked if she could give me a try. Totally shocked.. Just for the fact that it was only like the 3rd time I was taking her out. I'm respectful, so I'm not always trying to get ass the first night.. It gets better sometimes if you wait it out. Anyways, Nailed her for awhile, and we eventually went out that night a couple hours later.. came back for rounds 2, 3 and 4.. Stayed up all night and pretty much had a lockin.. One of the greatest sexual nights of my life.. Besides the time the girl wanted me to jerk off on her.. That was the best thing ever.. She told me to blow it on her tits.. Wham smacked one right off her face.. Her response.. Holy shit, you just blew the biggest load I've ever seen, and you had to blow it in my eye.. Classic
