I put the slave on the cross and I approach him slowly and sensually. After used him for a whole day, I decided to reward him by giving him a handjob. I feel his balls are full but his little dick has erection problems and needs help. I'll handle that. My hand grabs it and it starts to go up and down. I want to give it some dignity, but all managed by me and under my control. When he's close to orgasm, I freeze and order him not to cum. It holds back. I resume masturbating him and play in this way with a continuous up and down. It's my doll! He obeys my order to squirt and his sperm falls to the floor, like an abandoned waste...
