It's all about control, cock and mind... My prisoner only gets a release at a certain time per month, the rest he spends locked in chastity, his balls swollen and his mind desperately in lust. Today I will unlock his dick but the long tease will be agony for him and when I finally jerk him off, I let go off his cock, making the cum fly in the air and ruining his orgasm as he dribbles his spunk down my leather pants.
