Chastity and orgasm denial discussion

My wife/KH has devised a fresh and enjoyable chastity arrangement for the start of the year. On January 1st, I was presented with two choices: one is to unlock, receive an oral from her until orgasm, then re-lock for the remainder of the year; or two, roll the dice each month—if you hit a 7 or 11, you get to unlock and stroke yourself in front of her. If it doesn’t go your way, just wait another month. To give some context, I’ve been essentially locked around the clock for about a year and a half. Usually, she allows me to masturbate while she’s watching every one or two months. The last time she gave me an oral was roughly twelve months ago, and since going into lockup, there have been no more penetrative sex acts. So the prospect of another blow job was incredibly appealing (as I expected her to know!). Still, I held out for now. She has decided to extend this window until January is over. If you prefer, you can still take that oral route and orgasm before being done until 2019; otherwise, keep rolling those dice each month. It’s a wonderful setup and very thrilling!
