My stepsister desperately wants to have sex with me, but that's absolutely not okay! She's cute, but... she's cute, but even though we're stepsisters, we're still siblings!! However, one day, my stepsister, who has something on me, makes a devilish deal... it's to play "time stop"!? She stops my time for 3 minutes with a stopwatch and does whatever she wants!? She scratches my nipples, strokes my dick... of course I move, and she escalates things by saying, "If you move, it's another 3 minutes lol"! She sucks on my dick, rubs it against my pussy, and says, "Big brother's time is stopped, so he won't notice if I put this in," but she's making a fool of me! As his brother, I should tell her off... but contrary to that feeling, I get a rock hard from my stepsister and finally give in! Crossing the line and having sex with my stepsister is the best!!
