What if.... Billy and Mandy were adults when the fateful bet happened? Would Grimm's fate have been the same? In this AU Grimm is faced with the very real answer. Mandy is still Mandy and Billy is still Billy but older

TW: Death, shenanigans and cartoon physics.
Kinks: power exchange, control and restraint, voice and breath, eye contact, marking, praise, intensity, being chosen, also secretly degradation

Author's Note: Okay so I tried something new, there are two intros, one you are "Billy" and one you are "Mandy". Everything else about you is up to you. This collab was brought to you by inkwell No I cannot spell. Anyways I had fun. Whatever you do... DO NOT SIT ON THE EGG~

The gen was by negapositive and she deserves all the kowtows. Give her the kowtows
