Sex Genie: Pleasing My Master 147 Are We Doing Any Cardio?

"Are we doing any cardio?"

"Yep! You can choose thirty minutes on the bike or treadmill, whichever you will prefer."

"I guess I'll pick the treadmill," replied Stephen, eyeing several free machines up in the cardio section. "Thirty minutes is a long time though."

"Don't worry," replied Grace, with a twinkle in her eye. "I'll make it worth your while!"

What Grace had in mind for making it worth his while was standing in front of his treadmill, and pulling her sports bra up when he pa.s.sed the five minute mark, exposing her t.i.ts to him. Stephen nearly careened off the machine while Grace simply giggled at his reaction.

"Grace!" He hissed, breathlessly, taking a look around at the other gym patrons. "What if someone sees?"

"Anonymity clause, my love," she laughed, before covering herself back up again. "No one noticed a thing."

He had a look around for himself as if he didn't quite believe her at first. Sure enough, everyone nearby seemed to be in their own world, and focusing on their own workouts. There was a portly middle aged man two treadmills down who was watching the television in front of him intently. Another rail thin girl in the row behind him running at near full blast. She wasn't even paying them any attention at all.

Shrugging his shoulders, Stephen finally let himself relax. Yet, when he reached the ten minute mark, she did it again, while going a step further and also pulling down her spandex slightly to show off her mound and glistening lips.

"See how wet they are for you?" She moaned, running a finger through them. "It's yours as soon as you hit thirty minutes, you stud."

"Grace," he breathed, "You're evil!"

She just laughed before covering up again, and then blew him a kiss.

On and on she played the same little game for the rest of the time on the machine. At the fifteen minute mark, Grace again exposed herself completely, but sit in a chair with her legs spread wide, casually fingering herself as she moaned his name. At the twenty minute mark, she bent over the same chair, showing off her perfect a.s.s and telling him he could have any hole he desired.

By the last third of the workout, Stephen was almost out of breath and running with a full erection, which was straining his gym shorts to the limit. Grace thought it was extremely funny, and kept grabbing it at random times, even trying to stroke it in motion with his running.

"That's not helping!" He laughed, while trying to retain control of the situation.

She pulled her hand back with a giggle, "Oops, sorry boyfriend!"
