Picture space. Now picture all the stars, moons and planets fucking together. It's free group sex plain and simple. If there is a bunch of cocks and pussies everywhere fucking and sucking, that's group porn. It's usually seen in porn movies and not in space though. If planets and stuff start having sex type activities it probably means that the world is coming to an end because that stuff wouldn't be normal. So human group sex movies are like a fucking free for all of fucking. I really don't know what else I can tell you about group sex porn movies since I've painted a pretty picture for everyone to imagine. So yeah. Erm...I think i might watch a movie tonight. Maybe go play some hockey or something. OK! Bye, I guess. If your still reading this, you should stop. I'm going to stop writing now.
