[Wasisan] Miu Wants To Do Her Best To Be Of Service! (Digital Puni Pedo! Vol. 26) {Mistvern}

Miu is a devoted petite tomboy sister desperate to make amends after losing her beloved Nii-chan's backpack with his smartphone and wallet inside, insisting on offering her small, flat-chested body in earnest service despite his claims that he's not mad. Her clingy apologies on his bed quickly spiral into flush-faced, sweaty determination to please, taking the lead on top and begging for permission to prove her devotion while promising he can boss her around however he wants. Shy, blushing afterglow and the teasing reveal that the backpack was closer than expected set the stage for an intimate, ahegao-filled brother-sister affair driven by her insatiable need to be of service.
