[Desk Work (Ashita)] Mika-chan's Secret Supplementary Lessons (THE IDOLM@STER CINDERELLA GIRLS)

Mika Jougasaki stumbles upon rumors of the legendary "supplementary lessons" from upperclassmen and naively agrees to tutor Tomita for grades, only to find herself pinned and thoroughly used by the older, intimidating instructor who promises to "raise" her grades. Sweating and trembling through every intense climax as her speech devolves into pure incoherence, the busty idol learns firsthand that gossip of the underground wasn't an exaggeration. By the final page, she's left blissfully drained and impressed by the cum lesson, while her satisfied tutor declares raising her grades "so easy"—concluding the short but relentless romp.
