Sir told me I could have an orgasm as a reward for being good during my training. It however required me to do some tying up with rope which definitely made it a lot interesting.
I was naked already and Sir told me I had to tie my ankles, knees and hands before I could play with myself and have the orgasm. Tying my ankles wasn't too hard since I've done it a few times. To start with I lied on my bed so I would be more comfortable, tying my knees too so my legs were basically immobile apart...
