I got her to volunteer her body as a fucktoy for our friend as a birthday present.

It was meant to last 4 hours, but he ended up slicing most of the time into chunks of 5-10 minutes, or as long as it took him to cum while she blew him.

I stopped tracking time before he had used up his first hour. Watching my gf treated like a prostitute a dozen or so times was enough to stop caring how much longer it was supposed to last.

It all started because she told me a few times that he seemed very attracted to her every time they met at parties.
Then one night during sex I floated the idea of making her dress up sexy for him and offering her body as a present for his birthday. The idea was so fucked up we both got turned on by it.
