The OP Slime Girl?

"Of course it's fine. But stop standing there and help me get her off me!" Lillia felt depressed the slime girl she had invented to help control Blake's lust suddenly attached herself to her and would not let go! She was blue and transparent and even resembled herself. Of course, she had to use her own image when creating a slime girl who Blake was going to be having sex with. But she never wanted to be its mama! 

Noa smiled and went to pull the slime girl off her, but every time she tried to pull, her fingers slipped through the slime girl's body. She was shocked because Lillia was pushing on her with all her strength, and was unable to do anything. Noa did not understand just how strong and strange this slime girl truly was. She seemed to be even stronger than Lillia! "My hand keeps going through her!"

"Why is she so strong!? Ahhhh! I only gave her a drop of my blood, yet she is stronger than me, this is shit!" Lillia yelled out.
