She cleaned him up.

Frank pushed himself off and stood over Rachel, his cock semi-flaccid dangling over her face. "Thanks for the fuck."

"My pleasure!" she cooed, getting up to kneel in front of him. "Let me clean you up before you go!"

Frank grinned as he watched the blonde trainer hungrily licked his shaft clean of their mixed cum. "I enjoyed my workout today. I'll make sure to book you next time!"

"Please do, Frank!" she smiled as he pulled his shorts back on.

After tucking his cock in, Frank wondered if Katy was awake yet.

"Do you want to join me in the sauna, Frank?" the blonde instructor asked before walking away with her clothes in her hands, not bothering to dress.
