Step Mom's Friend - Truth or Dare

Cory's stoked her friend Cassidy's crashing for the weekend at the big house. Cassidy rolls in wearing those hot pink shorts and a little tank that matches. They head down the hall to the guest room, then Cory splits. Cassidy strips fast, drops her clothes on the floor, and stretches out naked on the sheets. Moments later Cory's step-son Luke walks in expecting an empty bed. Instead he's face-to-face with Cassidy sprawled out, skin glowing. She grins and asks if he wants to play Truth or Dare. When his turn comes, she dares him to fuck her and keep his mouth shut. No hesitation. He kneels between her thighs and rubs her clit in circles, nervous as hell. Cassidy moans, tells him it's perfect, then pulls him forward so she can wrap her lips around his cock. She sucks him until he's rock hard and glistening. Next thing she knows she's on top, bouncing in cowgirl, tits jiggling with every drop. Luke grabs her hips, thrusts up to meet her. She rolls onto her back, legs spread wide, and he sinks into her again. They grind in missionary, both whispering filthy things while trying not to moan too loud. Cassidy flips onto her stomach, pushes her ass up, and Luke fucks her doggy-style, hips slapping skin. Just when they're close the floor creaks outside the door. They freeze, hearts pounding, scared Cory's about to walk in and catch them mid-thrust.
