His first time A2M! Hard strapon fuck for the slave!

Today I came up with something very mean for my house slave. First he had to blow my rubber cock nice and wet with his hands tied and without seeing anything. As a reward for his blowjob skills, I shoved the strapon hard into his ass and took him properly. Without suspecting it beforehand, he then had to lick the dildo nice and clean. I also put the whole thing in POV. Do you think I was a bit too mean, or would you find it cool to suck the strapon again after sex?
