I've been locked and denied for a full month now by Dreamgirl (that's what I am required to caller instead of Mistress) who is my KH dominant wife. Last night I started leaking a bit and Dreamgirl scheduled a milking for this morning. Milkings have always been difficult for me to achieve but I felt so full and had a lot of pressure on my prostate which made me feel like I had to pee when I didn't that I was sure I would produce a good amount of semen. After about 15 minutes and three different devices a small stream began to dribble out but just then Dreamgirl changed the position of the vibrator and the stream stopped. She could not get it going again after another few minutes, grew impatient, and announced that I must not be that full and promptly added another two weeks to my denial. AGGGH
My Wife respect me after a period of four months as chastity I am full. I have to keep my chastity and it is very frustrating not to have an orgasm.
If you cannot deliver at the time your Mistress allows, then it is your fault. you must wait until the next time.
If I may offer a pointer, when you feel like you have to pee, relax and push like you're going to pee. I would love milkings, but sadly I'm not allowed them.
