My Childhood Friend is a Hidden Masochist

About this game

Kouda Minato, who lives next door, is a childhood friend of mine.
She climbs in through my bedroom window every morning to wake me up.
I don’t consider her to be a woman, and she doesn’t seem to see me as a man, either.
Our relationship is that of childhood friends, nothing more, nothing less… This morning, the two of us were walking to the station as usual.
“Sex…does it feel good?” I’ve never discussed a topic like this with Minato before.
I wasn’t sure how to answer… “If you’re that interested… do you want to give it a try?” As I said this, I blushed red with embarrassment.
“If it’s with Kohei…I guess it’s okay.” Since that conversation, I have been thinking about the true meaning of those words.
Was it just a joke? I couldn’t get it off my mind as I climbed into bed. Just as I was about to fall asleep, I heard the sound of the window opening.
“Let’s try some naughty things”
