The scene opens with the stepsister, her face flushed with excitement, being bent over the kitchen island by her Stepbrother. Her lacy thong is pulled aside, revealing her tight, pink hole awaiting penetration. "Oh fuck!" she gasps as he begins to penetrate her anally for the very first time. "Fuck me, Stepbrother!" His thick cock slowly slides in, stretching her to the limit. She moans and whimpers in both pain and pleasure. He slaps her ass, pushing himself deeper inside. She begs him to stop, but he knows she secretly wants more. With each thrust, the pain turns to ecstasy. Blood begins to trickle down her thigh, and he relentlessly fucks her until they both climax. Covered in sweat and lube, they collapse onto the floor, panting heavily.
