Treasure hunt
Hide a few naughty notes or items around the house for your partner to find in sequence. For example, a note in the living room says “Good job, now remove your shirt and go to the kitchen for the next clue.” In the kitchen, another note might have a small blindfold or toy attached and say “Put this on and follow my voice to the bedroom.” Each step builds anticipation until the final “prize” which can be you waiting to do whatever the final note promised. It’s playful and engages the mind.
