Anyone try this?

Hit the dance floor. Scour the dance floor for 2 girls dancing while facing each other.

Now bring your wingman. Park your crotch up behind the ass of one of the girls. Wingman does the same with the other girl.

She'll glance over her shoulder. If she likes what she sees she'll back that ass up. Grind and escalate.

The other girl, seeing her friend getting freaky, will be inclined to do the same. She'll look over her shoulder at your wingman. If he looks passable she'll grind with him. Wingman grinds and escalates.

Now you've created a sandwich!

You go home with one girl, wingman goes home with the other.

Anyone have success with this?
