Every time I visited my friend's house, I was always greeted by the kind and beautiful Ruri-san. Her warmth and charm made me deeply admire her as a teenager. However, there was one thing that troubled me—her voluptuous figure. For a boy going through puberty, it was so overwhelming that I couldn't even focus whenever I looked at her. One night, when I stayed over at my friend's place, I found Ruri-san lying defenseless on the sofa, fast asleep. Unable to resist, I stared at her body and frantically touched myself. So absorbed was I in the moment that I didn't even notice she had woken up. Her vulnerable form and gentle warmth deeply stirred my heart.
