Gracie's eyes glowed purple, it was then that Cain realized what he was making. Marrying a succubus was a death wish for most men. He will be fine now because of his high MP but later when she evolves more, keeping her satisfied will sap him dry.
'Well, it doesn't matter, even if she fully evolved I bet she won't be able to suck more than what her MP poll allows.' He simply had more than she could suck, as most completely evolved creatures end up with around 4500 MP. The elvish archmage Lilia had around 7000 MP and the dragon king had about 8000 MP. Cain in his prime had over 14000 MP and could even get it to 20000 MP with enchantments and magic items.
'Yep sucking me dry is impossible!' Cain thought as he apprised Gracie. He had 3024 MP now while Gracie had 650, she would take at least four days for her to kill him.
"So how would you like to start? Sketchy it may be but you won so you're going first." Cain said as he lay on the bed like a dead fish.
