Group plot angst

Plot 93: Bon Appétit
Muse A is in a committed relationship. Muse A loves their significant other dearly, but in the last couple of months, their spark has definitely fizzled out. Uncertain that they will find what they’re looking for if they break things off with their partner, Muse A tries their best to subtly improve the intimacy in their relationship; unfortunately, their partner sees nothing wrong with the conventional way they do things, so nothing changes. One night, Muse A’s significant other makes plans with an old friend from school–a double date for dinner. Muse B knew Muse A’s lover in high school; they were close friends until one of them moved across the country for college. The couples meet at a fancy restaurant and the old friends catch up over drinks and appetizers. The whole while, Muse A can’t help but notice that their lover’s old friend is making eyes at them across the table. Thrilled by the idea that another person finds them desirable, when their own partner hardly seems to anymore, Muse A makes a bold move–sliding their foot against Muse B’s leg beneath the table. The seductive act is received by Muse B with a subtle smirk and a light nod of approval. By the time entrees are served, Muse A and Muse B manage to slip out of the restaurant for a quick encounter. They make their way back to the table and act as normally as possible, adrenaline pumping through their veins over the bad thing they’ve done and can’t wait to do again. Plans are eagerly made for another dinner date while Muse A and Muse B are already thinking of how they can raise the stakes. 
Optional: This could be a group plot, incorporating Muse A’s partner and Muse B’s partner.

hi I just found this and I really want to do it. I need three more people. If you have kakao, then it would be easier for me.
