I have an enemy idea. Based on a similar previous comment about having an enemy involving breast/udder vore but I wanted to make one a bit more detailed:
Maybe a Cow/Minotaur with huge swollen breasts dripping with milk from previous victims. Upon spotting you she'll let breasts swell a bit more before squeezing them, spraying milk projectiles that if they hit you, your character would be hypnotized (curse stuff I guess) and slowly waddle towards the enemy. Once the protag comes into contact she'll be breastfed into more submission by the cow/minotaur, before finally being shoven into her breasts, turning into more milk. Maybe you can even add a post vore scene in case other enemies were around where they would come to nurse from her newly swollen chest (though this part is completelly optional)
