My sister, a shut-in, has an abnormal sex drive, so I'm in trouble... ~ When I teased her, she violently molested me... ~ Urara Kanon PIYO-080

I was mocking my otaku sister who only watches anime and reads manga; she's terrifying… It seems I've triggered my older sister's wrath. He was wrapped in duct tape and had an embarrassing photo taken of him… "Did your otaku sister play with your penis and make it erect?" "(Brother) I'll buy you anything, so please forgive me." "You're going to buy me something?... But I refused." My sister's behavior, uninterested in sex, escalated rapidly. Without realizing it, I became my older sister's pet, and finally, I let her in.
