"Diego Perez, the stepbrother, finds Bec The Barbie, his stepsister, in a compromising position. Caught with her towel barely covering her, she's masturbating, her dark hair sprawled on the bathroom floor. Diego's surprise turns to lust as he watches her fingers dance on her clit. Bec, noticing him, doesn't stop. Instead, she beckons him closer, her eyes locked with his. 'You wanna join, bro?' she pants. Diego, unable to resist, joins her on the cold tiles, his cock hard and ready for her. Bec climbs on top, riding him in a cowgirl position, her tits bouncing, while Diego films their taboo encounter in POV."
