slerm grub tf 2 (sketch) (Patreon)

While the victim´s identity is stolen by the grub, the snail that was placed on the genital starts to transform into a new kind of sex.

through the herm-hormones, male victims start to develop breasts as long as they are in their human form. The effect on females make their clit grow bigger so it simulates a penis, that fills out the snail from the inside.
