Icha Love Hatsujou Kemo Musume

Icha Love Hatsujou Kemo Musume' Academy"** – a school attended by demi-human beast girls.
It is an unusual school where half of both students and teachers are also futanari (hermaphrodites).

What demi-human beast girls cannot avoid is "Estrus (Heat)."
The task of handling the sexual needs of students who have entered their estrus period falls to the Estrus Sex Process Committee, commonly known as the "ESP Committee."
One day, a student named "Umaen" visits the two members chosen for the ESP Committee: "Inugami" and "Nekozuka."

Umaen arrives breathing heavily, panting and gasping,
and scatters a large amount of accumulated semen.

"You'd stored up this much?"
"Come on, I'll take care of it for you – pull out your dick!"
"P... please..."

What emerges from beneath her skirt is truly of a size comparable to a horse's.
No matter how many times she releases, her estrus does not subside, and the two gradually become more and more aroused...
