Sinning With My Sister: Chapter Two

It's August Ames' 18th birthday and the only thing she wants is a cock to finally pop her cherry. She's the hottest, most popular girl at school and she's done pretending a stolen vibrator is enough. She needs the real thing. That's where her big step-brother Johnny comes in. Johnny walks through the door and surprises her with a lame pink onesie. She thanks him with a tight smile, but makes it clear she's grown up. Booty shorts and skin-tight tops are more her style now. She turns around, arches her back, and sticks her ass out, giving him a full view. Johnny looks away and heads upstairs for a shower. August doesn't hesitate. She follows him up, unzips the onesie, and lets her big tits spill out. Her nipples are already hard. Johnny's hard too, cock straining against his underwear. She wraps her hand around it without asking, stroking him slow. They both know this is wrong, but that only makes her wetter. They swear they'll never tell. August climbs on top, lines his thick cock up with her tight virgin pussy, and sinks down slow. It hurts. She doesn't care. She rides him hard, grinding until her pussy clenches and she cums all over his balls. Johnny flips her over, fucks her doggy-style, and pulls out just in time to paint her ass with a thick load.
