Rope and a ballgag

Seeing what she brought back now Adam says "Umm, what the shit Sarah?" "Don't look so worried, the gag is so you don't talk when you're fucking Amy and me, even though she gets a little dumb when she's being well fucked, she'd still recognize your voice. The rope is here to help explain the ballgag, we, well I can tell her you wanted to be tied up and rode against your will. I'll tell her it's a fantasy you had ever since that one episode of Futurama, you know rhat one with the giant Amazons?" "Oh, okay I guess, just don't tie my hands too tight." Adam says as he consents. With his hands loosely bound Sarah pulls the mask back down and fastens the ballgag around his head. "Amy's going to be here soon, so just relax and let me get to work riding this monster of your's okay, Steve?" Sarah says giving Adam a little wink, before she slides her underwear off and then crouches above him slipping the head of his cock in between the lips of her tight teenage pussy. As she eases herself down upon her brother's familial fuckstick they hear a knock at the front door. A moment later Sarah's phone vibrates, she stops grinding her hips against Adam to respond, tossing her phone aside she starts riding him in earnest. Moaning each time she grinds his cock against her g-spot. Just as Sarah starts to ride Adam harder the door opens.
