Женское доминирование, тренировка страпона для моей шлюшки

I have been on vacation for two months and therefore I will check if my slave's holes are still receptive and stretched. I want to be able to fuck him hard into both holes with my strap-on. His dick is of course safely locked away in a chastity cage during this strapon training. First I let him suck my strap-on, then I push my cock really deep into his mouth until he has to gag. Then I put a mouth gag on him and my slave has to kneel in doggy position on the bed. Since I am a nice dominatrix, I stretch his asshole with my fingers and a smaller cock first. But soon I take him from behind with my bigger strap-on. Now my property is being mounted. I love hearing him moan beneath me. I keep increasing the intensity and take him really hard from behind! He definitely deserves a little cuddle after this hard fuck...
