[Synopsis]

I went to the beach on a school trip but I, Kojima Takashi, a gloomy guy with no friends, just watched my classmates playing...
I didn't go in the sea and while I was taking a nap on the beach, I was suddenly swept away by a big wave!
When I came to, I was on a strange deserted island...!?
I wasn't the only one washed up but the class's top gal, Minami Ayane, was with me.
I'm going to survive alone on a deserted island with Ayane, who I've never had any contact with before!?
Using my knowledge of anime and manga, I managed to establish a foundation for my life but for a virgin, the body of a gal is too stimulating...!
Moreover, as a thank you for helping me, Ayane approached me, saying, "I'll do anything for you"!?
"We're bored until we're picked up anyway, so let's have some fun 💕."
Alone on an island with no entertainment, the only thing we can do is have sex...!?
A dull guy like me has sex with a gorgeous gal!
As we get immersed in each other's bodies, our feelings will eventually get closer...?
