Learning Bead By Bead

Charity's been failing science hard, so she's got a tutor named Lorraine. One day, Lorraine gets kinky with the rewards. She's wearing these smooth anal beads stuffed deep in her ass - they're hidden under her clothes. There's a clear deal though. Every time Charity nails a question, she gets to grip that little ring, tug slow and steady, and watch Lorraine shiver as another bead pops free. "Goddamn, girl," Lorraine teases when Charity nails three rows in a row. Slowly the beads come out, one slick pop after another, and the last bead clears, Lorraine's wet all the way down her thighs. She grabs Charity, pulls her onto the couch, thighs open and hair falling down. Charity's tongue is there, hungry, lapping up the mess while both of them know this is the best reward pile they've ever fucked through. Charity's learning now. Damn right.
