Their car cruised along the New Hampshire highway at a reasonable speed. Once in a while a speeding car would aggressively shoot by on the left-hand lane. Megan ignored these drivers. Her 18 year old son slept in the back passenger seat of her four-door sedan; his head drifting over to one side facing the window. A thin blanket was draped over his body from the shoulders down. The duo was returning from a multi-day trip, spurred on by Megan's obligation to keep in touch with her parents. It was an obligation she made sure to fulfill; especially after the divorce.
When she left him, there were no tears to be shed. It wasn't that he was a bad man, but that they were no longer compatible. He wasn't some kind of wife beater, gambler, cheat, or rouge. He was a straight shooting man who didn't take risks. Neither in his personal life nor at his job at the federal building marked "Internal Revenue Service" in bold letters. It was true he had a knack for numbers. And he was competent at the job where he directed his underlings at that bureaucratic labyrinth of pencil pushers and penny pinchers. But it wasn't enough for her. It wasn't what she envisioned before marrying him. Of course she appreciated his financial status and his ability to at least try and control bureaucratic pile-ups that she was oh-too familiar with.
What she didn't know 19 years ago was the fact that his aversion to risk would slip into his personal life. In hindsight, she realized he was faking it until he made it. But for some reason, she was turned on by his sexual and emotional shyness. She knew the trope of the manly man; the no-nonsense primal and confident man that all of her girlfriends dreamed of. She knew that was the norm. She knew it was what she was supposed to be attracted to. If she mentioned this fact to any of her close friends, they would probably side eye her with a judgmental fascination. But somehow in that wild, formative roller-coaster we call life, her attractions and fantasies never ended up aligning with the "norm". She sometimes thought it stemmed from one of her first boyfriends in highschool. When both were new to the basic human functions of emotional and sexual intimacy. When both were, as one famous singer and songwriter wrote: "Working on the night moves".
That probably solidified something inside her. Probably. She had all but buried these thoughts of sexually-stimulating shyness about 10 years ago. 10 years ago when that elephant between herself and her husband was finally acknowledged. Undeniable and bright under the blinding spotlight of lonely nights and dissatisfaction with her sex life. When hard conversations between herself and her husband were unable to bridge the gap. When his lack of confidence and unwillingness to try new things wore her down to nothing. And so, like all good things...
She snapped back from her thoughts as another one of those speedy drivers zipped by; throwing a small gust of wind that lightly pushed against the car. These long drives always seemed to bring the past to the surface. Meanwhile her son Jeremy seemed to stir ever-so-slightly in the backseat. Must be dreaming, she thought to herself as the dotted lines of the highway swept underneath the car. However, this innocent interpretation was quickly replaced by one more concerning. Under the thin blanket, she saw a slight up-and-down motion disturbing the surface. His eyes still closed. His head still tilted to the side as if he was sleeping. She had a sudden realization that he was not, in fact, snoozing away the long trip home. Her son was trying to slyly masturbate in her own backseat! While pretending to sleep? Did he think she wouldn't notice because his eyes were closed? Did he think she'd disappear if he couldn't see her? A blazing feeling of shock, disbelief, and anger suddenly burned within her. Could he really be that dumb? Worse: Did he think SHE was too dumb to notice? That this out-of-touche woman was too naive to understand? This made her grip the leather-bound steering wheel just a little bit harder.
Or maybe....was he just that inexperienced? Did he not know how to deal with his "issues" yet? She knew the boy wasn't some stud bringing home cheerleaders on the regular. And now with these thoughts fresh in her mind, Megan realized her son had never really talked about girls. Not even about platonic meet ups, let alone dating. She supposed a boy like that would never want to talk about such things with their own mother. Especially if he was testing out the waters of the hormone-ridden high school experience. She could understand that part, but not the part where her own son would submit to his sexual urges in an obvious and inappropriate fashion like this. With these ideas coalescing in her mind, her former burning thoughts were doused with a cold bucket of understanding and....something else. Attraction? Was there some kind of minuscule sexual switch that turned on in the back of her brain? It wasn't comfortable at first. It was like that icy bucket had drenched her and gave her system a momentary shock. But as she got used to that metaphoric coldness, a new fire seemed to start welling up inside her. Something clicked. A mental wire was connected where one shouldn't have existed.
"JEREMY!" She half shouted, despite trying to keep a cooler tone.
Her son opened his eyes immediately, looking startled. Those slight motions from under the blanket came to a sudden halt. He looked into his mother's eyes in the rearview mirror while trying to force the look and tone of sleepy confusion.
"Hey...what's going on?" He said in a tired voice while unknowingly failing the bluff check his mother had just given him. She felt a bit of embarrassment for Jeremy's failure to convince her. Megan composed herself and continued.
"I could really go for some relief if you know what I mean. I think there's a rest stop coming up close to the border here. I figure you should know before you sleep through it."
At that moment, Jeremy was hoping beyond hope she hadn't seen what he was doing. In hindsight, he felt embarrassed and stupid for enacting this little plan to take care of his "business". He had gotten an indescribable horny urge about 15 minutes back. It must have been the boredom of the trip, combined with his frustrating lack of jerk-off opportunities at his grandparents cabin. He hated sleeping with his mom in the same room despite having a cot to himself. In truth, the excruciating lack of privacy seemed to only annoy him when one of those urges came on. Jeremy looked down at the seltzer cans he had dropped on the floor. He had knocked back a few cans trying to occupy himself on the long drive home. He worked to compose himself and looked back at her in the mirror.
"Yeah, now that you mention it, I could probably use a bathroom right about now."
Yeah. I'm sure you need to use a bathroom right now, she thought with a bit of understanding humor. I'm sure you could use 10 minutes for sure. Maybe 5 since you're just a horny teenager right? This thought was followed by a more urgent one: What was she doing here exactly? She did need to use the bathroom, sure. But she knew that wasn't the only reason why she was stopping. Something in her mind didn't allow this shadowy reason to come to the surface.
"Alright", she said with the slightest bit of cheer in the back of her voice. "It should be coming up soon."
In no time, the rest stop came into view on the right. She pulled into the exit and came up to the semi-packed parking lot. In front of the lot there stood a rectangular building with multiple doors selling alcohol, lottery tickets, and knick-knacks. Along the right side of the building was a line of porta potties probably meant for the occupants of large buses. Megan felt the heat inside her grow as her mouth went a bit dry; like a teenager on their first romp. She was really doing this, wasn't she? She had to.
"I don't want to deal with that disaster of a parking lot. Let me just...park right over here." She said as she turned towards the row of plastic bathrooms.
Seems like everyone at this place decided to use the bathroom in the store, she thought. Or just buying tax-free alcohol no doubt. It made sense, unlike this situation. She drove the car past the rows of porta potties until she reached a large handicap unit at the very end. Once parked, Megan unbuckled her seat belt and opened the driver door. Jeremy hesitated as he tossed aside his aid of concealment. Unbeknownst to his mother, Jeremy made a quick "adjustment" to his pants as he exited. He started towards the handicap unit with the green indicator on the handle. Megan had butterflies in her stomach as she witnessed her dumb parking plan come to fruition. Of course he'd go to the nearest free stall, she thought. A prime example of the path of least resistance. She gave an amiable smile as she opened the restroom door and held it for Jeremy. He gave a slightly awkward smile in return as he entered. A toilet seat sitting atop a large plastic box was attached to the opposite wall ahead. The urinal was in its standard position to his left by the door. The light inside was slightly dark and tinted with a green hue as the sun forced its way through the colored plastic walls. Besides the lack of foul odors and graffiti, it was what he'd expect from a roadside porta potty. What he didn't expect was his mother to briskly come around the door, enter the porta potty, and unceremoniously lock it behind her. Jeremy had a look of perplexed shock on his face as she turned to him.
"Uh, what are you doing Mom?" he asked with that same look.
"I said I needed to relieve myself. And I saw you needed to relieve yourself too. Right?" she said holding that same amiable smile.
"I mean yeah but uh, I need some privacy here. I think uh....the next one is open."
"Oh I'm sure." she said confidently. "I just thought you might need some help with this one".
"Mom I...don't understand..." he said in a flustered voice.
"Did you really think the pretend-sleeping trick would work? You think your own mom wouldn't see what you were doing back there?" Jeremy's face began to fill with a rosy color.
"I uh, really don't know what you're..." he began to say.
With this, Megan stepped closer to her son. All bets were off now, she thought. Her former burning was now a bonfire. Her anticipation had turned on the faucet beneath her constricting jean pants. She was desperate to rip them off, but knew it would be too soon for something like that.
"As your mother, I think its my job to help my son with his problems. And judging by your bold move in the car back there, I think that problem might be a little urgent don't you think?"
She stepped forward again and put her hands on his shoulders with a gentle touch. She was only an inch taller then Jeremy but that difference seemed to turn up her dials.
"I...uh...think I'll just wait in the...." he stammered before she cut him off with a kiss on his lips.
To his surprise this kiss was not just a motherly peck but a full-blown french kiss. The kind he'd seen and heard about but never experienced. Her tongue worked a kind of magic within his mouth and after the momentary shock, he began to reciprocate without knowing what he was doing. After a moment, she pulled away and smiled at him.
"I thought that would get your attention. But there's something else that needs attention."
She looked down at his pants and Jeremy's eyes followed hers down to his crotch. There was nothing apparent on the outside of his pants but he knew he was sporting a hard-on strapped up against his belly with his underwear. It was an important trick he learned early on during his adolescence. Megan took a hand off his shoulder and guided him over to the urinal. She came up from behind and pressed her body against his back. He felt her soft breasts squish up against him and gave the slightest shiver in response. She lowered her hands down to his pants where she zipped down his fly. Her head rested on his right shoulder while she paused for a moment.
"I think you might want to pull it out, honey."
Without a word, he freed his erection from its waistband entrapment and snaked it through the fly. He felt a sense of relief as it hit the outside air and stood ridged in front of the urinal. Precum had already coated the tip of his dick. With her head still resting on his shoulder, Megan reached down and gently grasped his shaft. Her left hand came up and splayed across his chest. She began to slowly stroke his engorged member.
