Mistress Sin Piedad has two slaves in an anal training program, one she uses to suck on her strapon cock, to make it nice and wet for the other slave, who gets his ass fucked long, hard and fast in the gyno chair. She's working them both up to take her monster dildo, but it shouldn't take too long she considers, so long as she fucks them hard with the ever increasing size of cocks in her armory!
