Beth and Kirsten Engage in Sexual Activity

As an infant, he's abandoned in a food bank, left in a disgusting pile of excrement behind a low-cost market. He never discovers his parents' identities but grows into a timid, withdrawn child at an orphanage managed by a group of compassionate women who strive to nurture each kid according to their specific abilities. He demonstrates remarkable mathematical skills, becoming a young prodigy who excels at adding, subtracting, sharing, and multiplying numbers. By the time he's seven years old, he's adopted by childless accountants Esther and Richard and enrolled in public schools. He aces his math and athletic classes, repeatedly winning first place in cross-country competitions, specializing in long-distance track events. This leads him to join Myrtlesham AC, a regional sports club.

At the tender age of eighteen, he encounters a chubby, unmarried female named Beth and immediately falls head over heels for her. Once school is finished, he rushes home for dinner with Esther, then sprints off to the sports club to greet Beth at the track. As they exercise, they engage in one-on-one, five-thousand and ten-thousand-meter races on the flat, even going over hurdles. After their workout, they clean up and settle down on a park bench, sharing energy drinks and an energy bar as they pucker up for a smooch.

Beth loves being kissed on the mouth, yet since she's fitted with a retainer, she limits her lip-locking. If he touches her hair, thighs, or breasts, she demurs, "Not until I'm older," and pushes him away.

Unable to contain his lust, he takes advantage of her in the longest patch of grass near the sports ground, forcing his tongue between her wire-filled mouth, teasing her palate. She responds by stroking his temples, cheeks, and neck, guiding his hand to her buxom chest.

She murmurs, "What should I do for you?"

"Remove your shirt and bra, please."

"Only if you let me see your penis first."

Totally in awe, he peels off his sweatshirt, revealing his smooth chest dotted with a scattering of cocoa-colored moles, then drops his shorts and trousers. His member is erect, rigid, and yearning for her. She shifts out from beneath him, pulls her fresh running shirt over her head, and unfastens her bra from behind her back. Her magnificent breasts, larger and rounder than he'd ever seen, spill free with nipples primed for his attention. He rests by her side, curious about her imminent moves.

"Suck my breasts," she challenges.

Against all odds, he complies, enveloping her breasts between his palms, planting kisses on her nipples one by one, as her fingers graze across his midsection and penetrate his rugged mop of hair. Her arm stretches out, caressing the taut muscles of his buttocks.

"Touch my pussy," she whispers.

He obliges, reaching into her groin area, exploring the folds of her labia and vagina. She playfully banters, "Fuck my pussy!" and slides from underneath him. She hoists herself up, stripping off her running shorts and sopping wet underwear, so he can see the messy, gushing depths of her naturally damp vulva. His penis eagerly penetrates her, stirring up monumental orgasms as his hips rush back and forth.

"Fill me with your cum!" she pleads.

He strains his body, unleashing wave after wave of lush semen into her inner sanctum, aware of her clitoris contracting in his grasp. He tries to thrust deep within her to catch every last wave of his climax. His balls feel as though they're climbing his ejaculating shaft. He's furious with ecstasy, squeezing her lovely breasts together, pushing one into her lips to suckle. Trembling with pleasure, Beth let's go of his erection, her oversaturated vagina shooting slick jus across his belly.

At the age of nineteen, she wins a scholarship to a sports college. This news devastates him, leaving him feeling lost and lonely. He grows estranged from his daily life, taking refuge in excessive eating and gaining weight. His body becomes a source of self-hatred, as he sees himself in the mirror, covered in folds of flab, a fat rear, and a bloated stomach. She was central to his existence; without her, his life loses meaning. He skips school, forgoes meals, and avoids everyone. When not alone, he is lost in his mind, reminiscing about their sensual encounters.

It's Richard who steps in, urging him to act in a way that would make Beth proud of him.

He's reluctantly dragged to the gym by his adoptive father, meeting Kirsten, a striking fitness trainer with a kind heart and a positive attitude. Through her relentless workouts, she removes the excess fat from his gym-drained body and firms up his muscles.

One volatile night, after a brutal workout, Kirsten asks him to wait for her while she changes. She enters the gym in a tight salmon-pink sports bra, loose paint-splattered shorts, and athletic sneakers. Captivated, he observes her hands as she grasps the cross-trainer handles. He notices her wrinkled and deformed fingers, thinking she must be a few years older than him, but exceptionally beautiful. Smooth skin and a new italic tattooed inscription on her right forearm indicate they're more than mere acquaintances.

The gym is deserted, the temperature stifling hot, the tension between them: electrifying, tangible.

"Come and join me," she whispers, not looking at him, discarding the white towel on her shoulder.

Enraptured, he stands behind her on the cross-trainer, watching her curvaceous body, in awe as she frees her breasts from her sports bra.

"New to this, right?" she inquires, taking his hand, instructing him to help her.

She guides his hands over her smooth, plump breasts. He's experienced nothing like this before. Kirsten is stunning, bold, disquieting, arousing, and in control. The tension inside him grows stronger, and he feels his testicles swell against his gym shorts.

"Haven't started yet," she purrs, then directing him to retrieve a washable pale grey gym mat in the core strength zone, to disrobe and lie on it.

"What if someone sees us?" he asks, touching her erect nipples.

"I'll lock up," she says, guiding him towards the mat, "Go lie down and wait for me."

He releases her nipples, reflecting on her openness and adventurousness. Compared to Beth, Kirsten is extraordinary. He strips off his shirt, tracksuit bottoms, pumps, socks, and pants, lying naked on the mat, waiting for her. Kirsten, eager to experience his hard young penis, removes her tie-dye shorts to reveal a salmon-colored g-string. She stands over him, turns, and exposes her shaved, dripping vagina.

"Well," she says, smiling at him, laughing at his shocked expression, "Would you like to fuck me?"

Throat dry, enchanted by her, his voice incapacitated by arousal, he quietly nods.

She positions herself over him, lowers herself onto him, and unites them forever. He's never fuck a woman's bottom before. Her anal muscle grips his cock, and it feels fantastic. He wonders if she defecated out of consideration for this anal intercourse.

"Don't just lie there, idiot," she snaps, "Fuck my arse!"

With vigor, he thrusts his cock into her bottom, coating his tip and shaft in her fecal slime, suspended in anal contractions, attempting to stimulate her into climax. She presses his hands to her firm breasts, cupping them towards her flat bronze nipples as she prepares to climax. Embedded in her anal fuck-hole, he senses her jus, her warm, lubricated body, pouring over his stomach with female ejaculate. Losing control, he releases his semen deep into her anus, and she crashes land on him, spent.

His phone vibrates. He hugs Kirsten tighter, gripping her bottom with his left hand as she slumbers with his dick stuffed in her butt. He speaks softly. It's Beth, inquiring if he'd sleep with her pussy behind the sports field when she visits him later this weekend. What else is there to do, really?
