Here's a promise based on the Netherlands vs Ukraine match that's about to start in a few hours:
- If the Netherlands wins, I will drink 2 litres of tea before going on a long walk in a diaper, and will mess it at the half-way point.
- If Ukraine wins, I'll wear a chastity cage and diapers for a week
- If it's a tie or the match gets aborted, I will cum in a face mask and wear it when I next go grocery shopping.
