Playing a prank on my sleeping schoolgirl sister, she suddenly woke up and begged me for bareback sex—I couldn’t escape as she locked my balls in a crab clamp and I ended up cumming inside her! Hiiragi Marina

While the brother is taking care of his sick sister, she falls asleep from exhaustion. Seeing her sleeping face, he becomes aroused, his concern for her intensifying his emotions until he can no longer suppress his desires and begins masturbating. Suddenly, the sister wakes up and passionately kisses him. In that moment of shock and confusion, she touches his penis and whispers, "Big brother, you're really pent up, aren't you?" He murmurs, "Stop it...", but he's already too aroused to resist. He quickly pulls down his pants and underwear, letting her jerk him off. As she teases him softly in his ear, she continues stroking before moving on to a blowjob. He nearly cums multiple times, but she withholds his orgasm, then makes him eat her out. Afterward, they begin intercourse in the cowgirl position. He asks, "Are you sure I can go inside?" but she firmly replies, "There's no option not to." They continue passionately in various positions—reverse cowgirl, doggy style, missionary—until finally, she locks his testicles in a crab clamp, leaving him unable to escape, and he cums deep inside her.
