My stepsister is desperate to fuck me, but that's absolutely out of the question! She's cute, sure... but we're siblings, even if only by law! However, one day, she seized my weakness and proposed a devil's bargain: "Time Stop Play." Using a stopwatch, she stops my "time" for three minutes to do whatever she wants. She scratches my nipples, strokes my cock... and when I inevitably move, she teases, "If you move, I'll add another three minutes~ lol." As she escalates, she sucks my cock and rubs her pussy against me, claiming, "Since Big Brother's time is stopped, he won't even notice if I put this in, right?" Stop making fun of me! I wanted to set her straight as her older brother, but contrary to my feelings, I ended up rock hard for her and finally surrendered. Sex between step-siblings who have crossed the line is absolutely the best!!
