Risa Kotomi, to put it simply, was a *3-year-old girl who loved sex. Her first experience sent her on a climactic rampage. She came and came and came.

As always she off to an orgy party in the park when suddenly she was attacked by lewdmares of the ultrasexual netherverse. Risa was exquisitely seized...

A strange being appeared before her.
"Sign a contract with me... I want you to become a magical girl!!"
It was like a scene from an anime! The lewdmares were attracted to her latent orgasm energy. When a woman cums, it produces a special raw material, and Risa's nymphomaniac multi-orgasmic ability was a rich reservoir.

They wanted her... The strange being wanted her... Tart... Risa agreed. She would protect the peace of the world, as well as get all the continuous sex she could ever dream...
