For an exam taking place in Tokyo, I ended up staying at a relative's house near the venue, far from home. Living there was Tsubomi, my 6-year-older cousin, who had always been kind and caring since I was little. She was someone I deeply admired and my first love. Lately, we only met once a year, but as I entered puberty, I found myself increasingly drawn to her body. Last year, I stole her underwear left in the changing room, and since then, my feelings for her have grown stronger each day. Unable to hold back any longer, today I sneaked into the changing room while she was taking a bath.
