[Okayusan] School Caste Prologue and Ch. 1-3 {Erf'} [Decensored]

A schoolboy madly in love with his cute girlfriend can't stop his thoughts from drifting to Matsui Riko, a classmate whose prickly underarm stubble and secret Friday trysts haunt him long after the final bell. Blackmail fuels their frantic classroom encounters—fingers buried deep until she's squirting, tongue-lashed into ahegao bliss—while an innocent invitation to study together threatens to blur the line between obsession and something real. Okayusan's decensored chapters unravel a school caste hierarchy where desire ignores social rank and one boy's loyalty is about to snap under the strain.
