Squat

She tells you to stop and to follow her to the next exercise. You can't decide whcih part of her to look at as you follow her to the squat rack; her huge flaring lats, her freakish triceps, or at her ass some more. Before you can decide you're already there.

She sets that bar at the proper height the commands you to put 8 plates on each side. You begin the arduous process, for you, of loading up the bar. When you done you turn to see her standing there waiting. She has stripped down to a tiny string bikini bottom that barely covers her pussy, it is bulging trying to contain her oversized clit.

"Okay, you're going to start behind me, get a few reps of my ass, then come around the front so you can get my quads. got it. And Jerk off at your own risk you little shit. If you cum you're going to lose more than your jizz"

She adjusts her shoulders and picks the bar up of the rack. The bar is noticeably bending under the strain of the 765 pound weight. She lowers all the way down, her ass barely a foot above the floor. She pauses then powers the weight up with a grunt. He stays behind her for two more reps. His cock is at full attention. He moves the the side for the next two reps, her grunts are getting louder.

You move around to the front for the final reps. The strain is evident on her face, which has become bright red. She lowers down again, as she rises her body is shaking and her thighs are quivering. They become noticeably larger as they become even more pumped. Down she goes again, she emits a loud scream as she rises, her quads becoming even larger. Sweat is pouring out from all over her body.

Despite her warning you cannot resist the urge the stroke your cock at the sight of this freakish display of power. One last time she lowers down, just as deep as all the others. She struggles to rise up but lets loose a primordial scream that frankly terrifies you. She powers the bar all the way up. Her whole body is shaking as she racks the bar.

You have never stroked your cock so hard in your life.
