The number are capped at 999, and it usually replenish when the girl sexual desire are fulfilled

Each arc has different girl and each of them got different supernatural power from those number , I remember the girl on the first arc is able to stop time, the number goes down everytime she use the timestop ability, the longer she stop time, the faster the number decrease. she use her time stop ability to kill her abusive parents are her bullies, and her male childhood friend kept preventing her to makes the situation worse.

Second arc is about a female middle school teacher who has crush on her 8th grade student boy, she use her ability to revert her body into a 13 years old girl instead of her original body on her 30s, and she's basically enjoying adolescent romance with her student while pretending to be a random 13 y old JS

There's more arc after that but I forgot, I wonder if anyone remember the title and if the scanlation already completed, because it's still ongoing back then.

Nvm, I found it https://www.mangaupdates.com/series/o7on4uy/bokura-no-fushidara https://www.mangaupdates.com/series/sezlqv5/watashi-no-fushidara

Seems like, I've actually read all of them, and there's no new update at all
