more glute work

Gracie whispered into the instructor's ear then turned to the women. "You will do whatever your told and believe that any exercise you're told to do in this class is normal!"

"OK, ladies," said the instructor. "Form a circle with about two feet between you and the woman in front of you and bend over."

The women formed a circle and bent over.

"Now, nothing is better to tone your butts than a good hard spanking, so spank the woman in front of you good and hard and work both cheeks."

The women obeyed and started spanking each other. The instructor grew more and more aroused.

Gracie yelled above the noise of the spanking. "Being spanked makes you horny. You love a good hard spanking. Nothing turns you on like a good hard spanking! The more you're spanked, the hornier you get!"

The women started breathing heavily and fought the temptation to moan aloud as they all became turned on.

The instructor turned to the woman with her butt cheeks pressed against the window. "Come over here and grab your ankles in front of me!"

The woman obeyed, and soon the instructor was smacking her exposed butt cheeks with gusto.

Gracie herself was growing aroused by what was happening: Twenty-two women, all growing more and more horny.
