Rose Caarter is unpacking after she has moved in with her new stepbrother, Josh Rivers. Josh is helping move boxes around. When he says it's the last box, Rose tells Josh that she has just one ground rule: She gets super horny around her period and he should avoid her because she will try to breed him.
Over the next few weeks the two become BFFs. When the week of Rose's period comes around, Josh doesn't care about the consequences because he misses her. Rose takes the opportunity to pounce. She has Josh blow on her because she's too warm. Gradually she has him blow her titties and then her pussy. When she has Josh feel how wet she is, Rose knows she has him where she wants him.
Pushing Josh backwards onto his back, Rose crawls on top of him and sinks down onto that nice fuck stick, riding in cowgirl. Rose hops off the D long enough to deep throat her stepbro, then she gets on her knees so Josh can lick her pussy and dive back in. When Rose spreads her thighs as she lays on her back, Josh shoves back inside and makes her squeal before filling her with a nice thick creampie.
