10 seconds before you go-go

This is the sexual act of teasing your partner for such an extended amount of time and just barely keep him from ejaculating. And when you think the time is right, you simply start having normal sex so he can't manage to hold it back for more than 10 seconds.

I don't know what to think...Stacy did the 10 seconds before you go-go on me, and now i'm neither satisfied, nor dissapointed.
