Katherine instructs her son

You felt bad for the boy as his mother watched him over like a hawk. It would have been bad enough if this were a job slinging burgers or selling cell phone cases, but having a parent watch your sexual performance? You were tempted to save the boy some anguish by pulling his mom into the orgy you and Diana were orchestrating, prepping the girls for Kevin. The two of you were in a pile with the remaining customers, rubbing and caressing their bodies as you all watched like a bacchanal audience to a stage play.

One saving grace was that the gym contract kept Kevin comfortable with sex in front of his mother. The only embarrassment was from the maternal scrutiny. Kevin continued to thrust into the petite brunette he was working on. She blissfully moaned for more. Katherine observed with a front row seat, getting her own share of cock from the defense instructor’s assistant, Jeremy. He slammed his dick into her from behind, doggy style while she observed her son. Katherine openly moaned and panted, taking it from someone other than her husband while in her son’s presence. While her body was being pleasured, her mind was still on her boy and how well he was doing his job.

As Kevin continued to plunge his cock into the avid gym goer, his mother’s face grew in consternation. It wasn’t from her getting close to climax either. She looked like she wanted to say something but was keeping it in. Even Jeremy was noticing the tension, taking longer, slower strokes to get through to the woman. Kevin’s mom was focused on her son though and barely acknowledged the muscular man’s dick buried deep in her pussy. Still, he aimed to please and worked his cock deep into the business lady. This seemed to distract her for a bit, with her panting growing heavier and her body glowing with pent up pleasure. In reality, you soon realized, she was pent up with the need to advise her son.

“Kevin!” she finally blurted out. “I’m sorry. It’s just,” she hesitated to complete her thought, but ultimately decided that he needed to hear it. “It’s just… you’re doing it all wrong!”

Kevin made an exasperated sigh. He was clearly used to this type of micromanagement. Katherine pulled herself off of Jeremy, dripping fluids onto the glossy finished wood panel floor, and pattered barefoot over to her son. She adjusted his position like one would handle a poseable doll until Kevin was contorted into a pose that satisfied her. He held as still as a mannequin while his mother placed her hands on his hips and started to rotate them, simulating the motion she wanted to see him make.

You could barely watch as Kevin was getting sex instruction from his mother. While the gym contract protected everyone from embarrassing sex experiences, unfortunately for Kevin, it didn’t extend as far as embarrassing mom experiences. A few of the girls had to stifle giggles at the scene and you could see the mortified look on Kevin’s face.

“You have to work your hips to get the best motion, trust me, the girls will appreciate it!” Katherine told her son.

Kevin grimaced but followed his mom’s instructions. Admittedly, the girl receiving the new technique was noticing the difference. Her moans became faster and higher pitched as Kevin was able to push in deeper and more thoroughly with his new stroke style. He picked up his pace and soon the girl had reached her peak, letting out a satisfied cry of pleasure before collapsing on the gym mat and pulling herself off Kevin’s cock with a satisfied grin.

“That’s my boy!” Katherine told him, giving him a proud hug.

“Moom…” Kevin said, sheepishly.

She kissed him on his forehead and went back to Jeremy. “I’m sorry, no more interruptions,” she said, crawling back onto Jeremy’s crotch to enjoy the rest of the show.

Kevin managed to thin the herd of waiting customers with his newly learned technique and was satisfying them at a faster rate. One by one, the figurative lineup shortened until it was down to a couple of more girls. Kevin’s stamina was commendable, able to keep himself going after so many women.

The next girl approached. She was a tall, slender woman with straight, flat reddish brown hair. You had just been fingering her while she stroked your cock as you were all watching Kevin do his thing. With everyone else complete, you joined Diana in pleasuring the final girl in line, taking the redhead’s left breast as Di sucked on the left and fingered her..

Kevin was too small to give the taller woman doggie style. He kept having to adjust his pose to fit but that would break their rhythm. They agreed to try a new position, so they improvised a pose that they could both work with. The leggy classmate rested on her side and Kevin moved between her legs so that they intertwined. He started to thrust into her.

“Uh..” Kevin’s mom started to say, before trying to hold her tongue.

Kevin knew she wanted to throw in her advice, so he sighed and asked, “What is it, mom?”

“I just think that you’d get better leverage if you just had her tilted up, hold her hips, dear…” she told him.

He tried to do as she suggested but it wasn’t quite right for her. She cocked her head in a judgmental manner, wearing a thin frown on her lips and rubbed her chin as she slowly shook her head. Kevin recognized the look of disapproval and rolled his eyes, growing tired of the constant scrutiny. He tilted his head at her, waiting for her to give further instruction.

“Lift her hips higher, dear,” she coached. He lifted the woman’s hips so that she was in an upside down bicycle pose. Kevin was hovering over her as he inserted his cock. She looked like she was dangling with one leg over his shoulder. “No no no… you’ll pull the poor thing’s leg off like that!” Katherine complained. “You need to come down lower, accommodate the lady, for heaven’s sake!”

Katherine once again climbed off Jeremy and marched over to her boy. She pulled apart Kevin’s legs so that he splayed lower to the ground, allowing his client to rest lower..

“There, you see? You can both be comfortable now,” she said.

“Actually, this is kind of an awkward position,” the tall brunette informed the mother.

“Nonsense!” Katherine dismissed. “You could go all night like this. Just use your elbows to hold your back and Kevin can keep you stable. Like this…” She laid down in the upside down cycling position to match the woman, then stabilized herself with her arms and bent them to hold up her back. “Son, put your penis in me so I can show this lady how to take it.”

You sat up in alarm! Up until now you have been hooking up random strangers and maybe platonic coworkers or friends, but this was entering an entirely different area, one you weren’t sure you were comfortable with.
