I never knew it could feel this good... The after-school bell rang... The hustle and bustle from a moment ago had subsided as if it were a lie, and you were playing the acoustic guitar in this empty classroom. Your defenseless ponytail swaying rhythmically was impressive... Something is stirring in my heart... Your fingertips and the sight of your back. It's easy to put into words, but it's so painful to convey. You don't know this feeling... "That's a good song..." I felt like my second hand had moved forward by just one second... Back then, with a beautiful girl in uniform. During recess, a girl who fell asleep in the nurse's office... a delusional oral sex. After school, while she was changing into her gym clothes... classroom sex.
