The precum, the twitching, the smell of a desperately aroused cock, the moans… they drove her wild. Slowly teasing him was one of her favorite ways to relax, except she had to keep control of herself or else he’d cum too quickly. She never let him know it but she never let him cum on purpose, and it felt delightfully wicked to feel his anticipation and hope surge and fall in waves when even she didn’t know when he’d cum.
That was months ago. Now that they have a chastity belt that he’s adjusted to, and she is finally liberated. She can get just all the precum, twitching, smell of a desperately aroused cock, and moans she likes, for as long as she likes, all without having to hold back, without having to think and watch him to prevent letting him cum too soon, even when she firmly presses her tongue against the exposed slit and licks back and forth for much longer than he can stand.
