Frank knelt behind her.

Frank knelt down behind her and pulled down her skintight yoga shorts and g-string panties to her knees.

"Now what?" she asked, looking back over her shoulder as he gazed at her perfect toned ass.

"I'm gonna fuck you," he grinned as he nudged the tip of his cock between her wet pussy lips.

"OOOOooooh yeeeeah," Rachel moaned as his cock stretched her cunt.

"God, you're tight!" he grunted when her cunt swallowed the last inch of his thick shaft.

"Oh fuck yes!" she screamed, as Frank grabbed her wide hips and started pounding her from behind. "God, I love your monster cock in me!"

Whereas other men his age would have already cum with a girl wildly pushing her ass back against his thrusts like Rachel was, Frank was still rock hard thanks to his medication. It did not take long for her body to tense up and tremble from the orgasmic build up.

"Ohfuckohfuckohfuck..." Rachel repeated, whipping her hair from side to side while Frank continued to mercilessly hammer away her spasming pussy. Then she flung her head back and let out an orgasmic cry. Frank pushed her head down and squatted over her upturn ass, churning his cock in and out of her cunt, bringing the trainer from one orgasm to the next without letting her recover.

"FUCK YEAH!!!" Frank howled, slamming balls deep into her cunt before releasing a torrent of semen into her womb. "FUCK. FUCK. FUCK YESSSS!"

Rachel let out a muffled orgasmic cry into the mat as she came again.

"I'm still hard and I still need to fuck you again, sweetie," Frank boasted as he pulled his still hard cock from her snatch with a loud audible slurp.

She grinned, impressed by his stamina.
