[Umai] Milady's Secret Side (Little Girl Strike Vol. 21) {Mistvern}

Bratty little ojou-sama Riri holds absolute power over her hopelessly devoted butler—escorted from school by car, then 'served' at home with his tongue buried between her thighs as an official duty she pretends not to enjoy. Straddling her powerless servant, she rides him hard while hurling insults, yet her tsundere facade cracks as she demands he call her by her first name and admit Riri is cute. With a gentleman's hand kiss and her sweetest commanding smile, she secures his promise to keep serving her utmost tomorrow and every day after.
