My wife doe that exactly. Gets me nice and hard and strokes me then stops and tells me to put my hard pens back in my panties. I never get to ejaculate except for maybe every 4-6 weeks. And when I do it's onto a spoon and immediately into my mouth. Now she is giving me ED medicine to make the erections harder and last longer. I am such a lucky Sissy Housewife Husband.
I wish my wife would stroke me but she keeps me locked in my chastity cage so I can't cum.
