From what I’ve read, be aware that Instant Female Magic should be called “Instant Sibling” it does not necessarily induce cuddling leading to nookie. You need to twist it with Ammo or Turn Up The Heat or something with -none, P79, etc.
Should you try to escalate kino with a person who does not expect it because their IFM addled mind is telling them you’re a safe teddy bear, be prepared for the startled reaction you’ll get.
In other words, IFM = affection… Ammo/TUTH = sexual interest
