There are times when your boy just needs to be reminded that the solution to his problems is found at the feet of his Master, or in Your case, suckling on Your hairy pecs.
When Your boy is unruly and unsettled, take him to the nearest bathroom, lock the door, and order him to feed. He may resist, but the familiar musky smell wafting off Your chest will affect him like a shot of adrenaline, and he will be reminded in an instant of his inferior and dependent position in life. As his tongue laps over the copious thick hair matting Your chest he will remember again that he is not a man; he is a fag whose sole purpose is to please his Master. You keep him shaved as an effective and demeaning way to remind him that only men have hairy bodies.
As he nurses and his hunger takes control, he will feel sated and once more at peace. Hold his head firmly against Your pec and take the moment to inform him that he needs an emotional and mental reset, which will happen as soon as you both get home. The last occurrence left him incapacitated for a week as the bruises and marks healed. He'll whimper and cry against Your chest but giving in is not a mercy and he will think less of You for it if you do.
Order him to lick the sweat off Your chest to distract him and slowly push him to his knees. Bad boys don't get cock. Make him lick the sweat from Your balls before pulling him to his feet. Wipe the tears from his eyes and assure him everything will be okay. Kiss him and lead by the small of his back out of the bathroom and back to Your table. His appetite will be gone. Keep him hydrated and finish Your meal. The ride home will be more tears and pleading. Unfortunately, that only makes Your cock harder and solidifies Your resolve.
