As Emma pulled into the parking lot, her son looked out the window at the fenced pool area. Already he recognized a few faces from school, tantalizingly bared in their skimpy one-pieces and bikinis. After parking she closed the trunk with one hand and caught up to Johny. She was wearing a bathrobe that covered up her body from her collarbone down to the top of her thick, fleshy thighs. Johny looked at her expectantly. He was wearing a t-shirt over a pair of shorts and flip-flops.
"You did wear your Speedo, right?" Emma asked with a grin.
"Why, are you afraid I was going commando?" he asked, meeting her expression with a cocky grin of his own.
"Bare it and share it," she replied cheekily. He laughed, but tried not to think about why his mom's flirty joke made him feel good. He glanced at the pool, hearing a bunch of girls yelling and laughing as they frolicked in the water, and suddenly felt very self-conscious walking through the fence in the company of his mother.
Johny surveyed the pool, feigning indifference, and nonchalantly took off his t-shirt, baring his chest. There were other guys there who made him feel a bit unathletic, but his genetics ensured that he probably wouldn't have to worry about developing a gut until well after high school. But he still hesitated for a moment while he rested his hands on the waistband of his shorts.
"You're gonna take them off, right?" Emma asked him quietly. "Not gonna leave me hanging alone out here, right?" She smiled while asking him, but Johny could tell she was losing her nerve. He sighed and rolled his eyes, then slid his shorts down his legs and stepped out of them. His blue Speedo briefs clung tightly below his hips, containing him snugly but leaving a lot of his body bared. He self-consciously reached behind himself and tugged one of the leg-holes down, snapping the stretchy fabric over his buttock.
"Oh god, I wanna give them a yank soooo bad," Emma sung to him quietly, low enough for only him to hear, reminding him of her threat at home. She reached behind him and pinched his Speedos between her fingers, tugging the fabric up into his cleft far enough to reveal the undercheeks of his bottom.
"Come on, Mom, knock it off!" he said irritably, tugging them back into place. "Not here, okay."
Emma chuckled to herself but let it drop. With a deep breath, she untied her robe at the waist and slid the terrycloth from her shoulders. Despite his pretense at disinterest and detachment, Johny felt compelled to gawk at his mother in her new swimsuit.
The swimsuit, such as it was, consisted of little more than a collection of blue strings stretched to their straining point over the curves of her voluptuous body. It was a sling bikini, with a few tiny triangles of blue fabric shimmering in the sunlight as they strained to keep her nipples and crotch from losing all modesty. The suspenders of the sling tied over her hips. She turned around briefly to set her robe down next to her bag, and Johny felt his cheeks flush hot as he saw the back of the sling was also not much more than a few strings plunging from her shoulders down into the deep cleavage of her full buttocks. She stood up straight once more and adjusted her dark brown hair about her shoulders. "So," she asked, "does it look okay? It isn't too much, is it?"
Johny tried to play it cool, his self-consciousness around his classmates doing battle in his fevered mind with his nagging and wholly inappropriate teenage lust. He had never before seen that much of his mother's body so openly on display, and the shock of so much bare skin out in public was more than he could handle. "It's...it's fine," he stammered. "I'm gonna go test the water." He walked away without another word and doused his body underneath the shower in the corner. The water was cold as it hit his skin, and though it made him shiver and get goosebumps all over, he hoped that it also helped to douse the rapidly growing erection he had felt stirring within his Speedo. Then he plunged into the pool.
But every time he started to relax, his mother would show up, trying to get his attention. When she saw him jumping off the diving board, she stood in line behind him and cheered him on encouragingly. When he did breast-strokes and backstrokes across the pool, she was soon beside him, swimming along next to him, with her modest little breasts, her slightly rounded tummy, or her effectively naked plump round buttocks dipping into and surfacing out of the water. He got the distinct sense that she was following him around, and the last thing he wanted was to look directly at her in that ridiculously skimpy, brazenly revealing "swimsuit" she was showing off in.
At last, some of the girls had started talking to her, and she eagerly engaged in conversation with them, laughing way too loud. At least she was distracted, Johny thought, and he felt like he could finally enjoy a few moments of peace and solitude in the pool and relax. But he noticed someone watching him.
Her name was Brandi. She wasn't the most attractive girl he knew at school. She wasn't ugly or anything, but he had never counted her among the girls he had crushes on. But Brandi was undeniably sexual. She had kind of a perpetually bratty expression, with an upturned pug nose, high arching eyebrows, and a lip curled in a knowing smile. And her green bikini with its yellow trim clung snugly to her voluptuous young body, showing off a lot of her tan olive skin, though still not nearly so much as his mother in her sling. Brandi sauntered up to him in the waist-deep water, wiping back her long black braids with blonde highlights. "Hi, Johny," she said in her usual sultry tone. "Having fun with your Mom today?"
He winced inwardly but tried not to show any indication of his embarrassment. "Really just needed to get out for a bit today," he said. "Thought I should get one last swim in before fall."
"Yeah," Brandi agreed. "Your Mom seems to have thought so, too. I mean, wow, she's really daring, huh? Wearing a suit like that, just showing off her entire body..."
Johny rolled his eyes yet again for her benefit. "She's pretty shameless. It's kind of embarrassing, really." He hoped Brandi hadn't seen his burgeoning erection when he'd first gotten into the pool.
"You're kinda showing off a bit too," she said, smirking. Brandi traced her fingertip along Johny's hip, following the seam of his tight Speedo. He shuddered delightfully at her unexpected touch. "Marching around the pool in this little tiny thing."
"I used to be on the swim team," Johny said. "I mean I tried out for it, but I had to let it go cuz of the pandemic and everything."
"That's too bad," Brandi said, letting a single fingernail dive underneath his low-slung waistband and trace along his lower belly. "I would have liked to see you perform."
Johny felt his face heat up from the sheer boldness of Brandi's casual exploration combined with her innuendos. Even if she wasn't one of his crushes, his hormones were driven into overdrive by her growing intimacy under the water. She stepped closer toward him, until her thighs were touching his own. As she looked up into his eyes, sticking out her tongue mischievously, she started to work his Speedos down his hips, teasingly peeling them down.
He swallowed hard, feeling his erection pulsing against his little lycra prison. He knew this was bad, that it wouldn't end well, but also he didn't want Brandi to stop playing with him. He hadn't imagined losing his virginity to Brandi but he wondered if she might give him his first handjob.
Suddenly his penis sprang free under the water. He felt Brandi lift up her knee, nudging it against his taut scrotum, as she stepped down between his legs. She pressed her thigh against his hardness as she stood on his briefs, pinning them to the pool floor while gently stroking his cock. The sound of the people at the pool around him rang in his burning ears as he knew that if anyone looked close enough, they'd see he was now completely nude under the water.
"You wanna have sex?" Brandi asked him. Johny felt himself on the edge of climax.
Emma grabbed his shoulder from behind. "Come on, Johny!" she said excitedly. "The girls wanna play Chicken so I need you to climb on my shoulders!"
Before Johny had any idea what was going on, Emma pulled him toward her - yanking him out of the Speedos pinned under Brandi's foot - and turned around, kneeling in the water in front of him.
Johny fell against her back, pulled off balance. Emma felt a distinctive prod against her and realized Johnny was inexplicably nude in the pool.
In surprise, she stood up, bursting out of the water. Johny, still clinging to her sides to keep from falling over, felt his toes tangle in the side-ties of his mother's sling bikini.
The strings were yanked loose and her entire suit snapped up into the air, dangling limply around her neck and leaving her bare, glistening wet body completely, scandalously exposed.
Johny slid down her back, feeling his ultrasensitive throbbing dick slide along his mother's wet body and plunge deep into her butt cleavage. Emma instinctively tensed, clenching her full motherly buttocks, and Johny, already edged to the point of no return by Brandi, helplessly began to ejaculate into his own mother's bottom.
Emma twisted around to look over her shoulder at her son. One of the high school girls yelled, "Oh my god, he's fucking his own mother in the pool!" Emma's face was crimson with humiliation, and she looked at Johny, still nude and clinging to her bottom, still throbbing hard, with a mixture of expressions. 'How could you?' her face seemed to ask him, but also, 'Oh, my poor precious boy,' and, faintly, 'Is that really how you feel about me?'
The sound of incredulous teenaged laughter, smartphones snapping pictures, and water splashing about the mother and son clinging nude to each other rang in their ears.
