"Babysitter's Titties"

Your babysitter is requesting a pay rise and says she's happy to do any additional jobs for that to happen. She knows your job is very stressful and would love to help you relax somehow. She notices the way you try to peek down her blouse from time to time, so perhaps she could tease you with her perky tits and you can wank your cock, and then you can pay her extra.. is it a deal?
