[Genki Tarou] Memories of When I Lost My Virginity to an Expressionless, Mentally Weak JS

An expressionless, mentally weak girl at a suburban children's center is drawn into a secret encounter when a visiting father leaves an envelope and invites her to change, leading her to stare at his erect cock and perform a raw, first‑time blowjob. She later shifts to a doggy style position, using her twin‑tail hair as a handle, and experiences repeated climaxes that leave her overwhelmed and physically spent. The story ends with a commemorative photo and a lingering sense of loss as she disappears from the center, hinting at the lasting impact of that brief, intense intimacy.
