[Warabino Matsuri] Sassy-Sister Complex! 4.0 (COMIC ExE 25) [Full Color] [Revelations72]

Miki's big brother takes a Sunday off work to tutor his bratty little sister, only to find her sprawled asleep — a selfish princess full of openings, huge tan-lined breasts spilling from her bunched sweater while long stocking-clad legs dangle off the chair. What starts as a brother's 'reward' escalates fast as he helps himself to her sleeping body, working her until she's moaning and trembling, never suspecting she's been awake and letting every second happen. When she finally 'wakes' mid-climax and catches her scumbag big brother red-handed, Miki flips the script — demanding weekly study sessions, one more round, and cake as an apology.
