[pan Koujou (Lemon pan)] My Classmate Is A Bad Girl [altuser]

Miko Kurosaki—'Kuroneko' to her classmates—catches a boy spying while she pees, and instead of ratting him out she wraps her small hands around the proof of his arousal and refuses to let go, milking him dry before gleefully playing with the warm mess. Between giggling cum-play and relentless teasing of her flustered classmate, the sharp-eyed troublemaker escalates things after class in their gym uniforms, where the teasing turns mutual and her perky little nipples get twiddled until she's the one melting and moaning. A girl-makes-the-first-move romp where the bad girl holds the bucket, the reins, and the last laugh—right up until her defloration leaves her seeing hearts.
