training day 2 riding training in different positions

Another day when I wake up tied up in front of my master. First I have to show my learned from the first training, i.e. unrestrained cock sucking on the dildo. In between, I always have to show off my body to him in a humiliating way. Then I have to push an electroplug into my buttocks which gives me electric shocks. Next, I have to put a huge plug with a cock in my ass, that hurt a lot. Besides, I had to suck the dildo again and again. In the end, I was allowed to fuck the dildo with my pre-stretched ass. I had to ride the rubber in all possible positions. Next, I woke up tied up on a small chair, with the dildo right in front of my cock. My master ordered me to ride and fuck him and finally to sit completely on it, that hurt a lot but was also horny. After many rides I was allowed to open my cage and finally cum my cock.
