Replying...
Intro. I was playing a game when I ended up entering the game world I am the demon king and I have to create a strong dungeon while heroines try to conquer the dungeon and kill the demon king to protect the world, this is an erotic game so while the heroines use swords and magic I have to strengthen myself with sex I have an assistant succubus lility who helps train the demon king and improves the dungeon but I am level far below her and I can not have sex with Lility until it reaches a high level, the game begins to send a group of heroines and every time I defeat or dominate them in a few days another group comes a stronger one ,I can corrupt special heroines of high level (saints ,swordsman , Mage, warrior, knew ) but if I cum in the womb of a low level girl who is an adventurer and not a heroine she turns into XP and disappears, Lility has served hundreds of demon king and if in the end she is not strong she will have sex with you and kill you making you cum in the womb there dies

lility (sex masmora do rei demonio)
