It's the same as what other places call a "Body slide". Essentially they're gonna rub their naked body all over you in ways they wouldn't for lesser packages. YMMV for every girl, every session. The lame ones lay on top of you and move up and down with your cock crushed between your abdomen and hers. If she's got a nice set, she might give you a russian finish. If she's fun, she might simulate riding you by sitting strategically in front of your cock and grabbing your cock while grinding. Once I had a girl at PA kneel between my legs, hoist my legs in to her arms, and put my cock between her tits for the wildest russian finish I'll ever experience in my life. She's long gone, can't even remember her name, but she was Polish?
Then again some are lame as shit.
Ultimately I never go for anything less than VIP/Body Slide. They give you whatever their top dollar performance is.
