I has a suggestion :v
It might be a big or hard one, but, a giantess maybeh?
Like, a humanoid giantess that could have different attack/lewd animations, like, to name a few:
various kinds of vore, like oral, anal, breast, unbirth, ect.
if the giantess is clothed, maybe stuff the girl somewhere, like in her panties or socks.
breast smothering maybeh
and lastly, maybe stuffing the girl in her shoes and rub her with her feet, or, the giantess doing things to the girl with her feet.
Yeah, it's a lotta stuff, but I'm just suggesting/saying, ain't forcing shit or what :v
It could work as a boss or something, dunno
