My second new thread

I'm looking to play a simple game with my other (neither of us are lifestyle, both just play switches).

The idea is each of us has a short number code. One is tied, the other tortures. If one of us can extract the code in a set amount of time, they win. If the other person holds out (or in my case comes), they win. A small wager (household chores, taking the other out to dinner) will ensure it's played in earnest. I like the numerical code because it allows the sub to give up slowly, in piecemeal.

My first question to the community: What are your suggestions for light games? I know the general response is "What works for you and your partner", because every one in BDSM generally has pretty different interests, but some creative suggestions to get the imagination going would be fun.

The games can go either way: testing uncomfortable sensations (ice, nipple clamps), teasing, and fun combinations thereof.

My second question to the community: What modifications or different games in a similar spirit do you play? What scenes do casuals enjoy most? Pointers to favorite stories in the library are always welcome!

I'm looking forward to hearing specific suggestions, as I find reading always gets the imagination going in fun places!
