◇Synopsis
My sister Miku Tomioka is sociable, beautiful, and an excellent student. She’s truly a perfect specimen of talent and beauty.
But one day, I discover an unbelievable secret.
(It can’t be… Miku of all people…!)
Somehow, Miku has been filming herself masturbating in my room and uploading the videos to adult sharing sites.
Why would Miku film herself masturbating?
Why is my room the filming location?
Thousands of thoughts swirl through my head, driving me mad.
I considered calling her out directly to ask, but if I said “Were you masturbating in my room?”, things would definitely become awkward.
“I guess there’s only one way…”
There’s only one method left to verify the truth.
That is… I need to catch Miku the moment she sneaks into my room.
◇Heroine
Name: Miku Tomioka (富岡 美紅)
Voice Actor: Nono Mitsuba
Measurements: 5’1″ / F-cup
Profile: A quiet, capable type who handles everything competently. Though she rarely shows emotion on the surface, the constant pressure to meet others’ expectations has worn her heart thin. She discovered masturbation as stress relief and escalated into uploading exposure videos online. She becomes intensely aroused by the transgression itself—knowing it’s wrong while doing it anyway—and only then does her carefully controlled emotion explode.
◇Protagonist
Name: Magorou Tomioka (富岡 真五郎)
Profile: A kind and serious young man who cares deeply for his sister. While he possesses normal sexual desires for his age, he has no particularly unusual fetishes.
