Hello Shy Hubby - I would tell your wife to train you to be a submissive sissy cuckold. I would have her suck your cock off every other day for six weeks. She starts to suck your cock and finger your ass - she tells you to expect to be fingered every time she sucks your cock and for now on - you are to be clean and lubed and to expect it. Then enjoy receiving your blow job while you are being fingered. I have her talk smut to you as she fingered now your sissy-pussy - make you say yes that you enjoy being fingered. Otherwise the blow jobs stop. By the sixth week, your sissy-pussy will respond like a pussy - you will crave being fingered and fucked with a toy and ready for a strapon when she tells you to expect her to fuck your sissy-pussy with a strapon cock.
