Tiny doppleganger inside own mouth.

[TheLastNameNotInUse]

I always liked the idea of of the pred creating a shrunken version of themselves, while still being the giantess; and puts both the prey and the smaller her in her mouth.

Inside, the "giantess" maneuvers the prey to the edge of the throat and has sex or forces the prey to finish her with their tongue. After that the pred either pushes the prey down the throat and gets the pleasure of swallowing/feeling and watching at the same time. Or even swallows her smaller self too and continues the sexuality and eventually just leaves the prey in there alone.

I like the idea of Rinoa using her sorceress powers to make this situation happen between her and Tifa.
