An older brother is teaching his younger sister how to study. Nana is asleep Nana her older brother is checking the answers while saying, "You're amazing, brother!" He says, getting excited by Nana's nape. The older brother escalates as he peers into her chest and touches her thighs and pants, and suddenly Nana wakes up and gives him a deep kiss. Big brother, are you pent up? It's good. Nana has been studying a lot lately and has been feeling frustrated. Nana pushes her brother down and strokes his dick while licking his ears and neck. Don't make a loud noise, or Mom and Dad will wake up. She covers her brother's mouth and gives him a handjob. Then she gives him a blowjob. Nana sees her brother's rock hard dick and can't help but mutter, "Amazing..." Excited, Nana takes her brother's hand to her crotch and lets him touch it. Her brother resists, saying it's not good to do it raw, but she inserts it raw herself! It's not good to do it inside! He uses a crab lock to stop his resisting brother from getting away!
