You mutter no, guilt twisting in your gut because you’ve already fucked your own stepsister way too many times. She smirks, knowing damn well you still crave her tight body, and climbs right on top of you on the couch before you can protest. Straddling your hips, she grinds her soaked panties slowly against your growing bulge, her perky tits brushing your chest as she dry-humps you with needy little rolls of her hips. Her fiery red hair falls around your face while she whispers how badly she needs you inside her today, rocking harder until your hands instinctively grip her ass. Like always, you cave fast, guilt melting under the heat of her relentless grinding as you groan and start thrusting up to meet her.
