I hear strange noises coming from my sister's room. This… could it be moaning sounds?! Is she masturbating?? Wow, really?w My sister always makes fun of me, so I want to make her embarrassed… Thinking this, I burst into my sister's room and she hurriedly tries to cover up. Guilty as charged.w Every time I hear her moans, I barge into the room and persistently stop her from masturbating (I'll capture decisive evidence with my phone someday). At that point, I didn't realize my sister's sexual frustration had reached its peak. Then, later on, while secretly filming my sister masturbating, that tragedy (even thinking about it now is exciting) happened.
