Melanie gets a licking

"You've waited a while," Josh says to Melanie. "My turn to give you some fun."

He stands up, takes Melanie by the hand, and leads her to a chair; as she is about to sit down, he pulls down her thong, out of which she steps before seating herself on the edge of the seat.

Josh spreads her legs wide in order to squeeze between her thighs to reach her pussy. He runs his tongue up and down before focusing on her clit, making circles, figure eights, and just lapping up and down, slowly stiffening his tongue as she becomes more and more aroused.

She moans, first softly, then louder, then even louder when she remembers that she has an audience. With his legs, Josh pushes himself back and forward, his regular rhythm filling Melanie with pleasure. She eventually reaches the edge, and stays there as usual; for one minute, then two, then five, then ten.

"What a tease," Mark laughs. "Don't take too much longer, I'm almost hard again, and she'll be begging for another dicking."

Josh continues on, to no avail. Melanie reaches down to finish herself off, but Josh grabs her hand, stopping her from stealing his orgasm away from him. He's seen her have multiple orgasms. He's given her multiple orgasms. Why doesn't she cum?
