This ripe body is just for me. Mutual Sadomasochism - Final by Appetite - Adult Sex Game

Namino Yuuta enrolls into a school under his mother recommendation.
This school used to be an prestigious all-girls school, but because of the declining number of students, it had no choice but to go coed.
Yuuta thought there would be a few male students here and there but to his surprise, he is the only male in the whole school.
Not only that but the ***'s dorm is all the way up a mountain behind the school. Yuuta a very shy *** feels uneasy and depressed about the future.
At least Yuuta's aunt, Risako whom he's loved since he was a little ***, works at the ***'s dorm as the dorm mother and caretaker.
One day, Yuuta arrives at the dorm earlier than usual, and finds Risako bound in a S&M rope play.
"Yuu-chan, stop, don't rape me"- Risako says, fantasizing.
After hearing that, Yuuta can't control his feelings anymore.​
