My roommate left me with his sex friend at our place and she invited two HOT Spanish couchsurfers over for the next two days.

The two couchsurfers only speak Spanish and the sex friend's the translator. They're about 20 to 22 and I'm breaking the ice tonight with bottles of wine.

I'm basically a shy guy and have no idea how to proceed. But they're so hot I'll hate myself if I don't fuck them.
