work those glutes

"Ok, ladies, we're going to work those glutes," said the instructor. "Turn around and face the back wall."

The ladies turned around.

"Put your hands on your knees, and push your butts back," said the instructor, glancing from ass to ass.

Gracie walked up to the instructor. "Watching all of those asses makes you horny," she said.

The instructor grew flushed. "OK, clench your butt cheeks and sway your hips back and forth at the same time."

The women did as they were told.

Gracie walked around the class. If she saw a woman with nice bubble butt, she would tell her she loved it when people ogled her ass, and it did not matter if they were men or women doing the ogling.

"Keep up the good work, ladies," said the instructor. She kept glancing from butt to butt and growing more and more aroused.

Gracie smiled. The woman running laps in her underwear returned to class, panting.

The instructor looked at the woman. "Wedge your panties up your butt crack, grab your ankles and press your butt against the glass window."

The woman did as she was told again, wedging her panties deep up her butt crack then pressing her exposed butt cheeks up against the glass window.

Gracie walked to the instructor. "You would love to lick and fondle those butts. You are obsessed with women's butts."

The instructor's chest stared to heave, and she wiped her brow. "OK, now for a new exercise."
