[ENG Ver.] A Tale of Immutable Love

Tentacles x G*ngbang x Purification SEX!

The tale of a human woman who fell to the demon realms and was captured by a demon.
Her body is sexually trained to become a guinea pig research vessel for lab creatures.
However, it would seem that she had already been trained by her arch-demon master.
He of course comes to her rescue... and her body is once again made perfect just for him.
Happily Ever After.

* This is not an NTR / cuckoldry themed work.
After rescue from the tentacle and g*ngbang scenes comes consensual sex.
