She can't land this virgin!

"Why won't it get hard?!"
"It won't budge an inch for you!"

Kotaro Kasamatsu is a high school student.
But he's not an ordinary one.
As the son of a lecherous alchemist and a jealous soldier, he is a virgin who's only interested in young girls.

Thanks to a contract left to him from his father, Kotaro lives with a succubus named Fam. She tries all sorts of tricks to deflower him, but her body is far too mature to draw his attention.

Thus begins an erotic comedy of sturm und drang (storm and stress) where chastity is tossed out the window, only to be found and picked up again.
