【coming to bed】The naughty and bitchy AitchiKyun Log 2

A collection of previously published school trip series in one volume.
(It’s called “Log 2" but it’s for the convenience of paper media.)
This is a story about a girl who loves to have sex, but during the trip she tries to hold back, but is caught and has to do it with her classmates for three days.
There is also an extra short manga that was drawn and distributed at an event.
