Just for context, my wife (26f, the dom) and I (26m, the sub) are planning some games for my birthday. The night will likely end up with she allowing me to cum by hand or oral, but we wanted to play many rounds of small challenges before that with rewards and punishments for completing or failing the challenges. We have some rough ideas but thought we could use more of a variety for these components, so just wanted to get everyone's thoughts on what else we could do or anything else that could make the night more exciting. Thank you!

Here are what we have in mind so far:

Rewards will be more of a pleasurable teasing like 30 seconds handjob or oral, 1 minute feet worship

Punishment will involve slight pain and humiliation like slapping balls and face, tickle torture, spit in mouth, pluck pubic hair.

Challenges we have in mind are holding breath for 30 secs while she does all she can to try to me make breath, or try to recite a paragraph in 1 minute under her distraction, or I try not to get hard for 30 secs while she tries to tease me, etc.

Would appreciate any input for this kind of quick but fun and arousing challenges, punishments and rewards!
