A bet with me. Get horny for the first file, then try to have a productive motivated day with the promise of release if you in your own opinion did well. Edging, encouragement, keep your hard dick but only cum at the end of the day. It might make it hard to concentrate but that's why this is a challenge.
If you succeed, listen to the reward and release mp3.
If you fail, the punishment mp3 tells you to try again and has some edging and cock slapping involved.
