Drew Fem!Fell because why not... and yes Swapfell turned Fell into a woman... so Swapfell can do some sinful acts to Fell as he's a woman...
Reasons...
1. Boobs...
2. Fem!Fell's thicc butt...
3.Fem!Fell will be submissive...
4. When a monster becomes female with the serum for a short while they will be in heat...

So... since Fell is more submissive when in heat he won't be really able to fight back because of it... so... any of the male Gasters might even force Fem!Fell into mating...
