Blackmailer by necessity: stepson fucks stepmother after she cheats on him with a black man

A young guy accidentally looks out the window and sees his stepmother sunbathing in her swimsuit by the pool, and when a black pool cleaner appears nearby, she bares her breasts. This is interesting, and he continues watching: how she sucks the black guy's dick, and then they go inside to fuck. After catching his stepmom cheating, the stepson demanded an explanation. But she didn't want to explain anything, she just fucked him and asked him not to tell his father about it.
