Peter sneaks into the toilet to have a quick wank but the lock is broken. He holds his foot against the door but gets so carried away that he forgets and moves his leg - just as Tanya walks in! She says sorry but then spots what he is doing. She tells him he is a dirty boy but she wants to stay and watch so she crouches down next to him. She rubs his legs as he jacks off and soon her hands work their way up to his cock, taking over and giving him an expert handjob until he cums.
