[Nanashi Novel] Cuckoo's Promise Secret Tutoring Session With Ex-boyfriend

A studious girl with a high ponytail lets her ex-boyfriend tutor her for the Karamatsu High entrance exam, but each session dissolves into sweat-drenched kisses and relentless sex that has her climaxing far more easily than she ever did with him. He taunts her about holding back for her current boyfriend—a netorare thread she denies between moans as his big penis drives her through position after position, from slow cunnilingus to deep penetration. The final lesson has her riding him in full schoolgirl uniform, phone pressed to her ear promising to attend Kara-High together, even as he empties himself deep inside her.
