Calling out to sis

Josh opened his door and called out to his sister. "Genna! Come up to my room!"

Ronnie hesitated, her fingers flickering in uncertainty but still compliant to his orders. "Whu-what do you need your sister for when you've got me here, Josh?"

Josh turns back to his mother and smiles. "That's where the fun comes from, Ronnie! You said that **** seems kind of fun with a few drinks. Well I've always known that you've wanted your daughter to give you a nice tonguing."

Ronnie's fingers slam back deep into her body and she moaned. "Oh, fuck, yes... just thinking of her hot little body on her knees licking me out with her hands cuffed behind her always got me so wet!"
