POV: your horny step-sister left her door open again and you couldn't help but notice while you were walking by. Innocently, you peek inside and see her wearing nothing but her underwear and getting ready for bed. You start to feel your cock throbbing as she lays down and slips her hand inside her panties and touches herself. She sits up to take off her bra and suddenly spots you! She tells you to hurry and come in and shut the door before anyone sees! It's obvious your cock is hard so she asks how long you were standing there jerking off watching? She's still horny and likes the thought of you watching, so she lays back and rubs her pussy some more for you. She tells you to touch it and eat it, dirty talking about all of those kinky taboo desires. Finally she wants you to fuck her, no condom so you both can feel everything. And don't even think about pulling out. She wants to feel your cum pumping deep inside of her! Once you're done she says you can never talk about this again!
