Luna Mills, her petite frame engrossed in her gaming chair, is suddenly aware of a presence behind her. Donnie, her stepbrother, has been watching her, his cock hard and aching for attention. He doesn't ask for permission, instead, he mounts her, his thick, veiny cock finding its way into her tight, wet pussy. Luna gasps, her fingers pausing on the keyboard as Donnie's huge dick fills her completely. She tries to protest, but her words are lost in moans as Donnie begins to pound her, his balls slapping against her clit with each thrust. Luna's small tits bounce in her tank top, her black hair swaying with the force of Donnie's movements. She tries to focus on the game, but the sensation of Donnie's cock stretching her, his hands gripping her chubby ass, is too much. She falls back into the pleasure, her body responding to Donnie's taboo touch, until she can't take it anymore.
