How about getting some muscle bound women gangbanged or bukkaked, could be interesting.

Yeah man!
Sounds like a winner to me.

Here are some script ideas:

A gorgeous, tan lined, hard bodied, muscle babe goes to the gym for her work out.
She's the only women at the gym working out with around 50 guys or so.
One thing leads to another (fill in your own pre-facial action here)and the next thing you know,she's wearing everyone's cum all over her entire face, hair, and body.
She then smears the cum all over her body till it's evenly coated and her skin is nice and slick.
As a finale, she gives the viewers a 1 or 2 minutes pose down session with her new body grease while cum is still dripping and drying on her face.... Fade to black.
