Slightest Touch

Mistress Lexi has her slave's balls clamped down tight in her bondage device. Lexi strokes the slave's cock, making him super hard and horny, bringing him close to orgasm right before she stops. She leaves the slave frustrated and eager to cum. Lexi tells the slave that if he wants to cum he is going to have to do it with her using just 2 fingers on his cock. The slave pumps his cock in between her two fingers, his balls pulled with every thrust. Lexi smiles, amused at the predicament she has her slave in. The more he thrusts, the more his balls hurt. Will his horniness prevail?
