[Ogino Satoshi] Seikatsubu He Youkoso Kouhen (JK Genkai Koubi ~Goui Sounyuu de Bachibachi Nikuana-ka~)

Shouta's Seikatsu Club—devoted to improving the sex lives of students—gains an unexpected new recruit when the stern student council president storms in and catches club president Rina, Yui, and Anna basking in a cum-drenched afterglow. Her scolding collapses into gasping surrender as the girls pin her down, teasing her huge sensitive breasts and fingering her slick pussy until her insistence that she's 'not feeling it' melts into shameless, teary-eyed moans. A few days later she's fully converted, the club wins official student council recognition, and Shouta settles into a peaceful daily harem pile with four adoring schoolgirls.
