He wants you to finish what you started

"Oh, Joy, my dear," Mr. Goreman sighs. "What you were doing felt so good. Couldn't you just finish up for me?"

You smile and lick the underside of his drooling cockhead before replying.

"Been a while since you've had a pretty girl suck your nice big cock, Mr. Goreman?"

"Oh, yes, ha ha. Yes, maybe never one less than a third my age. The guys at the retirement home would be green with envy."

"I'll give you my card to give to them," you wink.

Before he can reply you engulf his cockhead in the warm wetness of your mouth and lick at his oozing hole. You might as well get a workout while you're servicing Mr. Goreman, you decide. With some effort you gulp the bulging head of his cock into your throat. You spasm and nearly gag.

Mr. Goreman doesn't even notice, he just groans with pleasure at the feeling as you deepthroat him all the way down until your lips touch his balls. You swallow a few times, letting the muscles in your throat work his shaft, before you pull back and gasp for air.

You don't give yourself long to recover. Gotta keep that heart rate up!

With one hand you rapidly stroke the veiny shaft of Mr. Goreman's throbbing dick. Your lips and tongue bob up and down on him as fast as humanly possible. Your stroking fist pounds against your soft lips with each downward stroke. Your tongue swirls around and around his shaft and glides across the tip to scoop up the salty pearls of precum.

In the distance you can hear birds chirping and the sounds of a park in summer, but in the cool shade of the clearing the loudest sounds are your wanton slurping on the old man's petrified prick and Goreman's wheezing gasps of pleasure.

You look up at him so he can see you. He smiles plesantly and rests a hand on your cheek, stroking it kindly as his man meat spears between your sucking lips.

His cock swells. His breathing grows louder and louder.

"I'm going to cum, Joy!" He announces. "By golly, you're gonna make me cum."

"Mmmmmmm," you encourage him, still looking up.

His wrinkled old face scrunches up and his mouth flops open.

"Ahhhhhh!" He cries and holds onto your hair as you gulp his gonads.

Your mouth fills with warm goo, salty and sweet at the same time. Not completely unpleasant but so thick it's hard to swallow. Mr. Goreman's cock jumps between your lips as he pumps out a massive load of cum. You finally manage to **** down his jizz and lick up the dribbling remnants as you suck out the last of his load.

You smack your lips as you pull away and guide a few spare drips back into your mouth.

"You nearly killed me," Mr. Goreman laughs.

"Mwa!" You reply and give him a big kiss on his shriveling cock.

You bounce to your feet and pause to count your heart rate. 120. Not bad, but you need to maintain a higher rate for a real cardio workout.

"Thank you," Mr. Goreman replies as he begins to pull up his pants.

"Any time, Mr. Goreman," you chirp back. "I've gotta get moving though. You gave me a few more calories I have to burn off."

By the time the old man gets the joke you're already too far away to hear his laughter.

You still have a ways to go to the gym. Past the car wash and the high school. Nobody there except maybe a few teachers and janitors. But you could cut through the back parking lot and save yourself a little time.
