Mungitura cattiva prima della castità

My poor rubber slave first gets a very mean teasing with the promise when he should his load his cock will be locked up for 4 weeks in the chastity cage. Apparently, this only increases his lust and the gas mask does the rest. So it is easy to drive him against his will to an orgasm. After that, I just leave him in his vulnerable position and he can think about the 4 weeks of chastity he is now facing.
