The temptation to thrust was doubled, with the effect of the ropes binding his wrists and presenting him, prone, before her. He groaned with the focus of keeping his hips still. He couldn't control the throb of his cock, as she licked and sucked just right, knowing how to drive him to the brink of madness, pulling off just before his hips angled forward, seeking just a little more friction.
His eyes fluttered to see her move away from him. She began to undress herself, a task he often helped with, but couldn't from his current position. He groaned, helpless and hard, in his bonds.
