Strapon chastity husband

My wife surprised me on our wedding night and sprung a strapon on me and said she was taking my anal virginity and ten years later I saw read a story about a wife locking up her husband and begged my wife to get one. I was seven inches when we started and 6 sizes smaller she’s shrunk my penis. I only get strapon sex from her in my bum and mouth and haven’t been allowed in her pussy for over three years now. I cannot get or hold a hardon anymore and am lucky to get three inches before it goes limp. My wife makes me lick her ass and sometime her pussy but not so much she says faggots don’t get pussy. I have to wear the strapon with 9,10” cocks in it to pleasure her pussy or hold it while she fucks it and use a vibrator. How our sex life has changed fo the better.
