Feeling bad, bullying. ~ I was made to cum 100 times to protect the one I love...

"The second time, you'll get to cum with a lot of pleasure," he says, repeatedly giving her the sweet, numbing sensation of pleasure.
Rahime is a transfer student with a stronger sense of responsibility than others.
Unable to overlook her friends being bullied, she decides to go to the bullies by herself!
The condition she was given was that "in exchange for quitting bullying, Rahime would become their toy"...?
Rihime's body is played with in front of everyone.
She doesn't want to come from his caresses, but... it's too good to think about anything else...!
