[Umai] Fall In Books (COMIC Megastore Vol. 10)

A bookish schoolgirl's quiet study session spirals into a blackmail-fueled ordeal when a bespectacled boy catches her and forces her to act out a manual's every instruction—vibrator pressed to her clit, blindfold tight, her soft thighs trembling as she fights to stay composed. The stakes climb when he bends her over right among the shelves, her moans carrying dangerously toward browsing patrons while hands grope her heavy chest and a harsh voice hisses at her to keep quiet. By the final page she's roped and spread wide, ahegao-faced and blissed out, breathlessly declaring herself the heroine of her own story.
