It's step-Father's Day and your step-daughter has the best idea for a gift - she knows how much you want to impregnate her. She wants to show you how much she loves and cares for you. Her pussy was already wet, and she was fertile and ovulating. She'd first have you stroke your cock to make sure your cock was hard and your balls were full of semen. Did you like seeing her big tits and pink pussy? She showed you every inch of her body, then masturbated with you. She stroked and sucked your cock, then she'd invite you to breed her. She was ready to be filled with your seed. Impregnating her was the perfect gift.
