Should I do that? My girlfriend's PERVERSE PLEASE

I can finally live out my fantasies. And do things that I have often played out in my imagination. I've often imagined what it would be like if I was fucking a guy and his girlfriend was watching us. So I grabbed my girlfriend from the other day and her boyfriend and played the whole thing out. And I have to say it was really cool to see how I was being watched and to see how horny it made her to watch us. I think the guy also realised how horny I was and how much I needed it, because he fucked me really hard. Well, what do you think we should both let him fuck us together?
