My slave is already fixated in the gyn chair, while I prepare his asshole with my fingers. Once he is stretched enough, I start the double-hole training by driving my strap-on deep into his asshole, while simultaneously pushing another toy into his mouth. He must learn to function as the perfect slut for me! As a special highlight, I present him with a massive radish that I bought fresh at the supermarket for his anal needs. I insert the increasingly wide vegetable deep into his ass and enjoy seeing him reach his limits under the enormous stretch. After the radish has served its purpose as preparation, I move on to the extreme and sink my fist into his stretched-out hole, where he must endure the intense feeling of being totally filled, as I move my hand deep inside his guts.
