The Size-drain Succubus' Endless Shrinking Sperm-milking Experience

You are caught by a terrifying succubus who drains half your height every time you cum. You are tormented by the overwhelming size difference and are milked endlessly as you shrink. In the end, she swallows you with her "special place"...

[Character]
A succubus who drains men's semen to sustain herself.

Despite being a succubus, she poses as a human and runs an inn.
Whenever she finds a man she likes, she guides him to a special "milking room", where she enjoys her meal.

Normally, milking a man's semen results in their death after absorbing their life essence, however, in her case, she drains their size instead.

Every time his semen is drained, the man's height is halved, so he is swiftly shrunk to a tiny size and played with as her toy.

Ultimately, her prey are shrunk to microscopic sizes, and she "disposes" of them in various ways depending on her mood. (swallowing whole, blowing away with a breath, etc.)

This time, she'll find the best way of disposing of you, her prey.
