Okay so I randomly remembered it today so basically ml nipple trains mc by cutting the tips of mc’s nipples and then mc wears bandaids a lot and then it heals and ml cuts them even further down. I remember mc wearing a white shirt after getting the bandaids off and getting hard when the freshly cut nipples brushed against his shirt.
Please help me find it 😭 I was thinking it was from reverse thinking but it was not. I do know its from something hardcore
