[Koori] Zesshokukei Danshi, Seiyoku o Shiru Ch. 1 (COMIC Ananga Ranga Vol. 31)

An exhausted, booze-worn man barely catches the last train home, only to doze off and wake to a busty schoolgirl slumped unconscious against him. His long-starved lust wages war with his conscience as he strips her tie loose and bares her lace-trimmed bra, marveling at her divine cleavage while she never stirs. What follows leaves them both drenched in sweat and shame, and when the terminal arrives he flees into the night screaming at his own body, to be continued.
