[GM4GM] we both have a main character that hate each other but love gambling. We gamble with magic spells and GM for the other as they try and deal with the spells effects.

(I believe this works best if we both play a female main character but can be changed to female vs male)

A small tavern in a fantasy world hosts a particular gambling table. One that we use every week. Gambling magic spells to try and humiliate the other and get their brains fucked out (assuming this is FvsF)

This can be all kinds of things. Tits growing when the person drinks cum, ass growing when it is smacked, when the person sees a cock they have to suck it, even more extreme things like an animal going in heat when they see the person. The spells can vary from physical changes to mood changes to environmental changes to mental changes to cursed items.

This world is filled with all the fantasy kind of stuf like magic, potions, quests, monsters, different races, etc.

The gambling part will be kept simple. We do different rounds. We decide before the round what the winner gets. For example, 2 spells, a magic item and a dispell on themselves. Then we flip a coin and the winner can cast 2 spells on the loser, give them a magic item and dispell a spell on themselves. Then we play a new round.

When we decide this is enough for now we play out the events during the week as our main characters try and avoid the effects of the spells but ultimately fail. After a week the spells end and we play another round to try and get revenge. Trying to ruin each others reputations and lives.
