Slave Is Made Horny and Gets Air Taken Away

Slave Canvas is bound on all four limbs. Mistress Miss Yara and Lady Lyviane have put a breathing mask with only a tiny hole in it on the slave. The slave struggles to breathe. The two women aggravate this by taking turns to sit on his face. The slave is aroused by the smell of the mistresses, but can't get hard because his cock is trapped in the penis cage. Lyviane enjoys arousing him even more with her tongue in the cage. The slave gasps for air under Miss Yara's bottom. Finally, the mistresses briefly open the cage, only to close it again immediately.
