[Personal Photography] A student sister and her perverted brother, who were unconscious during unprotected sex, suddenly became awake. To ease the awkward atmosphere, the student sister and her perverted brother engaged in a spell-based game. (STSK-152)

I really wanted to have sex with her. Inside my sister's vagina. I disguised myself and made her completely unconscious and have a primal sex dream...it felt so good...it felt so good...I just wanted to ejaculate inside...My sister woke up. Of course, she found out, and then things went wrong. We were good friends, but things have been a mess since that day. I decided I couldn't live like that anymore, so I decided to change my mind and write something that starts with the letter "re". There are 4 pairs of siblings.
