Your muffet, 5 guilty pleasure, please and sorry.
SFD!Muffet:
Muffet is a little beast in many senses. She enjoys to tease and torture and has a thing for young, strong flesh. (Even bones ;) )Her guilty pleasure is something way worse tho. She thoroughly enjoys receiving information through sex. It’s an old geezer? A young boi? A killer? A cute mistress? It all doesn’t matter. She will seduce them and get the information she seeks. She’s perfectly able to sweet-talk anyone who has some form of sexual desire. Her favorite information partners are in the royal place, Snowdin or Colé. Muffet is a bitch in the very sense and enjoys that even though she shouldn’t. (She is aware of her position and makes sure people do not forget their places. She is a mafia boss too after all.)Muffets seconds guilty pleasure is dusting people after the sexual interaction. She’s having the time of her life killing the monster right after his high slowly fades... so that the monster will notice his personal doom slowly coming back to its senses.
Not to mention she has this tick to check out everyone interesting. She has so many hands, why not use them.
