Ok... so you couldn't resist the urge of seeing your step-sis naked. It starts off as playful sexual tension, but then as her clothes start to come off... it gets very real! Your brain is telling you this isn't right, but your internal primal instincts won't stop her as she starts to stroke your hard cock. Before you know it, she opens her mouth and you feel your tongue around your tip... then her legs spread as she guides your throbbing meat into her swollen wet vagina. Its all happening so fast, you're pounding her as she moans! Your balls swell up with cum, and you hear your step-sis say... cum inside me! Do you pull out or drain your fertile nut deep inside of her?
