Tentacles x Gangbang 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 gangbang scenes comes consensual sex.
