He knelt down in front of her and seemed to take ages untying her sandals. She had her legs slightly apart, and he must have been able to see right up her short skirt. See there's a girl named Sarah Corr in my chemistry class. Long, black, hair. Exotic face. Sexy, green, eyes. Long ass legs. 34C tits at the very least. An ass that looks like she robbed a Kardashian at gunpoint. You get the idea. Well, she likes to run around in tank tops and booty shorts.
