A heart-break NTR comic where a girl is taken by another guy in a "king game" during a school trip.

A girl in my class
who always makes fun of me: Tsubasa
Hayami I was in love with it before I knew it.

One day, she suggested that we play with
four men and women, including us, on the night of a school trip.
I jumped on the proposal.

On the night of the school trip, we were supposed to deepen our friendship through unrelated play.
However, it is a king game that started with a light rhythm, and little by little you will take off the saddle.
Hockey games, undressing each other, deep kisses...

And my friend: Kudo, who was swept away by the atmosphere of the place, starts having sex with
my favorite girl: Tsubasa Hayami.

The girl I love in front of me is being held by a friend, but
I'm just in love with her, so I don't have the right to stop it.
It wasn't supposed to be like this. I just wanted to get along with her a little more.
