Synopsis
I’m going on a trip with my sister for two nights and three days and having sex with her!? At the order of my sister, Nonoka, I ended up traveling in a group while pretending to be her boyfriend.

I’m gonna cum!” Nonoka was always strong, but was I going to lose to her foolishness and have sex with her for the first time!?
