Harem Camp!

"...please do as you like to us"
As a result of being in close contact with defenseless girls in a small tent...
--One night, Kensuke is enjoying a solo camping trip when a mysterious boy, Haruki, appears in front of him with a harem of three girls.
Out of jealousy and spite toward Haruki, Kensuke decides to sleep with one of the girls in the harem.
Drunk and in a fit of rage, he starts crawling at night in a pitch-black tent.
The girl turns her back on him and silently resists, her breathing becomes rougher, and the feel of her excited soft skin...he can't hold back any longer!
Kensuke looks into her face to cross the line, and what does he see?

*It will be made into a TV anime with the title “Harem Camp!”!
