Dice game -feedback appreciated!-

First, if you have any ideas to make the game more diabolical please share! Though I think it is pretty diabolical as is!

My wife and I have devised to help make my orgasms more random and give me hope of contact with her (which is rare for me!). Basically, it works like this... If I give her good enough head she lets me roll a dice twice. It is a 10 sided dice numbered 0-9. So can get between 0&18

Roll 0-12 I get to jerk off while she watches
Roll 13-15 I get to jerk off while worshiping her feet
Roll 16-17 She will rest her foot on my cock while I jerk off
Roll 18 She will give me a handjob

(Thanks to Hando for helping update the dice rolls and making my life more difficult!)

Needless to say, this game basically reinforces that I'm her pussy licking hand humper, but it does make things a little more exciting! I love when she looks at me and says something like "aw better luck next time" as I begin to jerk off without any physical contact from her.

Recently added a new rule...

My wife had actually used more forgiving dice rolls earlier (basically a 16 or higher = a handjob) and I earned a handjob, first in months! Here is the new rule she came up with...

Rule #2 Whenever I earn a handjob I have to roll the dice again. The number I get is the number of dice rolls I will have to go without the option of a handjob/her getting me off included. I rolled an 8! So the next 8 dice rolls there is no hope for me! When I got the 8 she told me "That's a good roll for me!"

Let me know what you think!

the way my wit likes to play with dice, i start out rolling 4 dice, whatever number chums up that is how long i go without release. once i get to release she adds an additional dice and i roll and see how long i go. she does this up to 6 dice then we start back at 4 so i do not get to cum very often and she luvs it. i service her needs and she gets to ignore mine or tease me for days.
