A curious onlooker peeks through a crack in the wall, watching as the masseuse, dressed in nothing but a skimpy pair of panties and a revealing top, straddles her client on the massage table. Her nimble fingers dance along his shaft, making him groan in pleasure. She leans down, taking him deep into her throat, her head bobbing up and down as she gives him the best 'happy ending' he's ever had. The voyeur can't help but adjust her own panties, feeling a pang of jealousy and desire.
