It could happen but in a real scenario the girl would almost immediately inform the guy. I mean who are you doing it for? If you want the sex too, you’d ask the dude to actually “do” the sex. Why would you just lay there and have some guy rub his dick on you without saying a word?

Ehhh. I definitely had sex in my younger days where someone would start doing something, and I'd be like, "This seems like a weird form of foreplay, but let's see where it goes" and then they'd be done. 

Luckily back then it was rarely "one orgasm each" sex, so there's be another try.
