Aline, a restless housewife, invites Roberto, the handsome pool cleaner, for a private 'lesson.' She's a 'natural' at deepthroating, her throat contracting around his cock as she takes it to the hilt. Her husband's unknowing presence adds a thrill as she spreads her legs, inviting Roberto to fuck her married pussy and later, her tight ass. Aline's moans of pleasure mix with the sound of water running in the pool outside, a symphony of her infidelity.
