A young prostitute teaches the wives, and eventually the husbands in her neighborhood the art of lovemaking.
At 9:30, a young wife fucks her husband's co-worker at her place. Her female neighbors, who are supportive of her affair and I'm not sure why, use delaying tactics on her husband when he comes home early, giving her lover time to hide in the closet. Her lover has to stay inside the closet for a while while the neighbors, with the help of their neighbor, the young prostitute, think of ways to distract her husband so that he can escape.
At 54:25, the young prostitute has lesbian sex with the young wife while her husband is sleeping.
