Why do I hear the voice of Chris Guerrero in this manga? Well maybe I watched Overlord too much... But hey wouldn't the Voice Actor fit and about the Japanese sub for this one I think Satoshi Hino would fit too.... Just my Opinion sorry.
@zenyo actually remember reading a story where a demon queen does that to a heroine. Seals her all the way up to her clit then just constantly has her orgasm using a slime iirc. The ending is basically that the other countries submit to the DQ and she’s just like “ill free you... eventually.”
