I'm the neighbor girl, resting over while my folks are out of town. You're have a little sleepover with some of your friends & get a little rowdy, waking me up. I grumpily ask what y'all are doing and you tell me arm wrestling. I beg you to let me play too, "c'mon why not? do you think you'll get beat by a girl?" My mocking makes you all agree & I sit down ready to arm wrestle. I flex a bit & I tease each guy a little differently before and during our match. I arm wrestle 4 older guys and win all of them!! I absolutely humiliated them with my strength. I tease them further & I stand up to reveal my big meaty secret under my pj's. I pull down my pants a little to show the big bulge.. I'm not just stronger than you all, I also have a bigger cock! I think our friendship is going to be different now, neighbor boy!
