Here's a couple of the trailers from in between the films of Grindhouse.. and they are explicit and there are titties.

Werewolf Women of the SS - Rob Zombie
Thanksgiving - Eli Roth
Don't - (not sure who?)

There's a bunch on there. I really liked the Thanksgiving one. When that girl does the split on the trampoline? OUCH. Zombie's was good too. Bad quality though.
