Alright, this is gonna be a helluva lot more specific than you're probably used to, so bare with me.

I'm gonna need:
1) Girls either bent over or on all fours, showing their ass.
2) Nothing explicit shown: no pussy, no asshole, no tits (preferably). Clothing can be as revealing as you want.
3) Their face needs to be fully in sight, not hidden or masked or some shit;
4) No fucked up proportions, ass or chest being bigger than her entire body.
5) Preferably no loli
