Brook has been tasked with doing a stock check of all the leisure centre's assets. She walks into the men's changing room to inspect how many lockers and benches there are and finds Justin in just a towel! She tells him not to mind her and to carry on, but when he drops his towel and she sees his hard dick she has to take a closer look. She strokes his throbbing erection with her pen and then asks him to wank for her. She strips naked and spreads her ass cheeks to tease him and he soon rewards her with a big cumshot that flies through the air!
