mida00308 [MIDA-308] I accidentally witnessed my shut-in, socially awkward sister masturbating, and my sanity collapsed. Without noticing she had already climaxed, I went into a frenzy of piston thrusts. Tsukigumo Yoru @video

mida00308 [MIDA-308] I Witnessed My Hikikomori Loser Sister Masturbating and Lost All Sanity. She Was Still Cumming But I Didn't Care and Kept Pounding Away — Tsukigumo Yoru @Video "I saw it..." — My sister's room is so messy she can't clean it up. She's been wearing the same lame T-shirt since middle school. She devours erotic doujinshi and her eyesight is terrible. On top of that, she's a shut-in NEET. A textbook loser girl... Of course, we're siblings, so I never had any interest. — But then I caught my sister masturbating dead seriously! In that moment, my morality, ethics, and sanity came crashing down with a roar. I transformed into a lust-driven monster fixated on my own sister.
