10 Minutes of Ballbusting to Earn Cum

Tied to the bed and released from his chastity cage, his swollen blue balls are just aching for release. And ache they shall! I made him an offer, that if he could endure ten full minutes of hard ballbusting, that he would be allowed to cum. If he fails, he has to wait a whole week until we try again... I set my phone down, and start the timer. Within the first minute he taps out.........apparently because he couldn't breathe. So picky.... I re-tie his arms and leave his mouth exposed. Now we can properly begin! :) I punch, kick, knee, elbow and paddle his vulnerable, massive blue balls with delight. Will this poor sub of mine endure a full ten minutes of torment and cum all over himself? Or will he fail miserably?
