Sister Loves Helping Her Step-brother

Bloody and bruised, the step-siblings met each other's eyes in the dimly lit room. Their clothes were torn to shreds, revealing their twisted bond of incestuous lust. The sister ran her fingers through the blood matted on her brother's chest as they panted heavily from their recent frenzy. She leaned forward, her pierced nipples grazing against his rough skin as she whispered,"I love helping you relieve your stress." With a growl, he pinned her to the wall and slammed his erect cock into her womb, causing her to scream in mixed pleasure and pain. They moved together in a primal rhythm, their bodies sliding across each other's sweat-slick skin. As they neared their climax, their passion turned violent; he bit her neck hard enough to draw blood while she scratched his back until it bled as well.
