IENFH-015 When I was playing a prank on my sleeping high school sister, she asked me to fuck her raw instead. I was about to cum, but she locked me in a crab hold and I couldn't escape, so I came inside her! Marina Hiiragi

An older brother is taking care of his sick younger sister. He is concerned about his younger sister. His younger sister falls asleep. The older brother is excited by his younger sister's sleeping figure. He starts masturbating to his younger sister. His younger sister suddenly wakes up and gives him a deep kiss. The older brother is surprised. The younger sister approaches him and asks, "That's what I should be saying, isn't it? Why are you masturbating to your younger sister's pleasure?" The younger sister touches his penis and asks, "Big brother, are you pent up?" The older brother says, "No, stop it," but his penis is fully erect and feels good, so he just lets it happen. The younger sister takes off his pants and underwear and starts a handjob. The younger sister gives him a handjob while verbally attacking him in his ear. Then she gives him a blowjob. The younger sister stops him from climaxing many times. The younger sister makes him perform cunnilingus on her and then they do 69. From there, she inserts in cowgirl position. "What? Are you going to put it in?" "There's no choice but to put it in," she says, and inserts. They gradually get excited as they go from cowgirl position to reverse cowgirl position to doggy style and missionary position. The sister gets excited and locks on to him with a crab grip. The brother can't escape and starts moving his hips and cums inside her.
