The drive to the Legacy Center on that warm late-June morning felt almost ceremonial.
Golden sunlight spilled across the countryside as Ethan guided the family SUV along the winding roads toward town. Rows of thriving orchards stretched across the landscape, their leaves shimmering softly in the summer breeze. The air conditioning hummed quietly inside the vehicle, but the windows were cracked just enough to let in the living scent of Kinridge at the height of the growing season—warm earth, ripening fruit, freshly cut grass, and the faint sweetness drifting from the Kin River somewhere beyond the trees.
For once, no one seemed in a hurry.
The morning carried a sense of anticipation that made even the familiar roads feel different.
In the passenger seat, Elizabeth rested one hand protectively over her stomach. A peaceful smile lingered on her face, softening her features and giving her a glow that seemed brighter with each passing week. Every now and then she glanced out the window at the orchards rolling past, as if trying to savor the moment.
Behind her, Sophia and Isabella occupied the back seat. Both were visibly excited, though neither seemed willing to admit just how nervous they were. Their conversations drifted between hopeful speculation and playful teasing, only to trail off whenever the reality of the day settled back over them.
For the first time, they were going to see their babies.
More than once, their hands found each other across the center console, a silent gesture of reassurance that neither commented on.
Ethan caught a glimpse of them in the rearview mirror and smiled to himself.
The vehicle was filled with an unusual mixture of emotions—excitement, anxiety, curiosity, and wonder All three women had dressed with care for the occasion — flowing, feminine outfits that celebrated their changing bodies rather than hiding them. Elizabeth wore a soft, ivory sundress with thin straps and a gently empire waist that skimmed over the subtle curve of her belly. Sophia had chosen a light sage-green maxi dress that hugged her athletic frame while flowing beautifully around her legs. Isabella wore a delicate lavender wrap dress that accentuated her curves and early pregnancy softness, the fabric swaying with every movement.
They chatted the entire way, voices bright with nervous energy.
“Do you think we’ll actually see them moving?” Sophia asked, one hand resting protectively on her stomach.
“I hope so,” Isabella replied, smiling. “Even if they’re just little beans right now.”
Elizabeth laughed softly from the front seat, turning to glance back at her daughters with warm affection.
“No matter what we see today,” she said gently, “they’re already real. All of them.”
From the driver’s seat, Ethan remained mostly quiet, offering small smiles and occasional comments when directly addressed. He was trying hard to be the steady one — the reliable support the women had asked him to be — but inside, his nerves were buzzing. After cleaning up from his morning work in the fields, he had put on something nicer yet still comfortable and revealing: a soft, charcoal-grey cropped tank top that clung to his sculpted chest and ended just below his pecs, fully exposing his toned abs and the dark, enticing treasure trail that disappeared into the waistband of his shorts. Paired with it were his favorite pair of black athletic shorts — short enough that the bottom curve of his firm ass peeked out when he moved, and worn low on his hips to show off the deep V-lines and the top of his thick pubic bush. The outfit was clean and put-together, but left very little to the imagination.
From the driver’s seat, Ethan remained mostly quiet, offering small smiles and occasional comments when directly addressed. He was trying hard to be the steady one — the reliable support the women had asked him to be — but inside, his nerves were buzzing. The women had “volunteered” him as their emotional support for the appointment, and while he was honored, the idea of sitting in a room full of pregnant women — especially these pregnant women — made his stomach tighten with a confusing mix of pride and anxiety.
Or at least that was the official reason he kept telling himself.
In truth, the knowledge that these three women — his own mother and his two older sisters — were all carrying his babies filled Ethan with such raw, overwhelming lust that he was dangerously close to cumming in his shorts just from sitting next to them. He had even squeezed his heavy cock and balls into a tight black neoprene cock and ball sheath that morning in a desperate attempt to edge himself and maintain some control until he could get Isabella alone again later. She had refused to let him creampie her before the appointment, but had already sucked him off four times that morning, draining load after thick load down her throat while teasing him about saving the rest for after they heard the heartbeats.
He shifted slightly in the driver’s seat, the restrictive vice doing its job but also making his already massive erection throb painfully against the thin fabric of his shorts.
As they pulled into the Legacy Center’s elegant parking area, the building itself seemed designed to calm and celebrate. Wide glass windows reflected the surrounding gardens, and inside, the waiting room was a sanctuary of fertility and hope.
Soft, warm lighting bathed the space. Beautiful, tasteful art adorned the walls — paintings and sculptures of pregnant mothers in various stages of bloom, glowing with life. Subtle floral scents drifted through the air from discreet diffusers. Plush, comfortable seating clusters invited families to relax, and gentle instrumental music played softly in the background.
The three women practically glowed as they entered, their excitement palpable. They signed in and found a quiet corner to wait, still chatting animatedly about what the ultrasound might reveal.
Ethan sat between them, trying to project calm steadiness while his heart hammered in his chest. His powerful thighs were spread slightly in the low chair, the shorts riding dangerously low and doing very little to hide the growing tension in his lap.
Sophia noticed first and grinned mischievously.
“Look at him,” she teased, nudging Isabella. “Our big strong support guy looks more nervous than we do.”
Isabella laughed and leaned over to pat Ethan’s knee.
“Poor Ethan. Surrounded by three pregnant women. Must be rough being the only man here.”
Elizabeth smiled warmly, reaching over to squeeze his hand.
“You’re doing wonderfully, sweetheart. We’re so glad you came with us.”
Ethan forced a small, crooked smile, shifting slightly in his seat as he tried — and failed — to ignore how his thick cock was already starting to swell against the thin cotton at the mere thought of what they were about to see.
“Yeah ... happy to be here,” he managed, voice a little rough.
The women exchanged amused, affectionate glances. They had no idea just how hard this morning was going to be for him.
--- The ultrasound room was spacious and warmly lit, designed to feel comforting rather than clinical. Soft beige walls, a large examination bed with fresh linens, and multiple large screens on the wall for family viewing. The technician, a kind middle-aged woman named Mara with a gentle smile, greeted them warmly.
Before they began, one of the assisting nurses — the pretty brunette named Lena — glanced at Ethan with open curiosity. Her eyes traced over his tall, powerfully built frame, the cropped tank top clinging to his sculpted chest and abs, and the low-slung shorts that left his thick thighs and the top of his dark treasure trail on full display.
“Excuse me,” Lena asked with a playful, slightly flirtatious smile, looking between the women, “but who is this large, good-looking young man? Is he the father?”
The room went quiet for half a second.
Then Elizabeth burst out laughing — bright, warm, and genuinely amused.
“Oh, how silly!” she said, still chuckling as she reached over and affectionately squeezed Ethan’s shoulder. “No, no — this is my son, Ethan. He’s here as our emotional support today. We roped him into coming with us.”
Sophia and Isabella both giggled at the mix-up.
Lena’s eyes widened slightly in surprise, but she recovered with a quick, slightly flustered smile.
“Oh! My apologies. You just ... carry yourself with such presence. I assumed—”
Ethan gave a slightly awkward smile, rubbing the back of his neck as his cock gave another painful throb in his shorts at the unintended compliment.
“No worries,” he said, voice a little rough.
Mara smiled and got them started.
One by one, the women lay back on the table.
The ultrasound room was spacious and warmly lit, designed to feel comforting rather than clinical. Soft beige walls, a large examination bed with fresh linens, and multiple large screens on the wall for family viewing. The technician, a kind middle-aged woman named Mara with a gentle smile, greeted them warmly.
“Three at once? We love big families here,” she said cheerfully. “Let’s get you all scanned.”
Elizabeth went first. She lay back on the table, lifting her sundress slightly. The cool gel made her shiver as Mara moved the wand slowly over her lower belly. The room fell into a hushed, reverent silence.
Then the screen flickered to life.
Two distinct gestational sacs appeared.
Two tiny, flickering heartbeats.
Twins.
Elizabeth’s hand flew to her mouth as tears instantly filled her eyes. “Twins...?” she whispered, voice cracking with joy and disbelief.
The room erupted in soft gasps and delighted laughter. Sophia and Isabella both squealed and grabbed their mother’s hands, all three women tearing up together.
Mara smiled warmly. “Two healthy babies. Everything looks perfect so far. Congratulations.”
Next was Sophia.
The wand moved ... and Mara’s eyebrows rose in pleasant surprise.
“Another set of twins,” she announced with a grin. “Two more strong heartbeats.”
Sophia let out a stunned, joyful sob-laugh, covering her face as fresh tears spilled over. “Twins...? Oh my god...”
Elizabeth and Isabella immediately pulled her into a tight, emotional hug, all three of them crying and laughing at once.
Isabella went last and received a single, perfectly healthy baby.
Five babies.
All at once.
The room was filled with pure emotional chaos — laughter, tears, overlapping exclamations of disbelief and overwhelming joy. Elizabeth was openly crying happy tears, pulling both daughters into a tight group hug while they were still half-covered in gel. The three pregnant women clung to each other, overwhelmed with emotion.
Ethan stood right beside the bed the entire time, supporting each woman in turn — a hand on his mother’s shoulder, then Sophia’s, then Isabella’s. When the heartbeats began to fill the room — five rapid, strong little thumps — the sound hit him like a physical blow.
Thump-thump. Thump-thump. Thump-thump. Thump-thump. Thump-thump.
His cock surged violently in his shorts, thickening instantly to full, aching hardness. The heavy shaft throbbed painfully against the thin fabric, the fat head leaking steadily as the reality crashed over him: His mother was pregnant with twins. Sophia was pregnant with twins. Isabella was pregnant with his child.
Five babies.
All his.
The overwhelming knowledge — combined with the sound of their strong heartbeats — nearly made him cum on the spot. His balls tightened, his powerful thighs tensed, and he had to fight with everything he had not to groan out loud or soak the front of his shorts right there in the ultrasound room.
The overwhelming sound of five strong, rapid heartbeats filled the room — especially the two pairs of twins from his mother and Sophia — hit Ethan like a sledgehammer to the chest.
Thump-thump. Thump-thump. Thump-thump. Thump-thump. Thump-thump.
Each tiny heartbeat was a brutal reminder: these were his children. Growing inside his own mother. Inside both of his sisters. Five lives he had unknowingly created.
His cock surged so violently it felt like it would tear through his shorts. The thick, heavy shaft throbbed painfully hard, the fat head leaking a steady stream of precum that was already soaking through the front of the fabric. His balls felt tight and heavy, churning with the desperate need to unload. He was flushed, breathing raggedly, visibly struggling to hide the massive, obscene bulge straining against his low-slung shorts.
Mara, the technician, noticed immediately. She had seen this reaction before with particularly potent donors. With a discreet glance at her two young assistants, she gave a small nod.
“Claire, Lena — could you please take our young man here for some additional support?” Mara said smoothly, keeping her tone professional. “He looks like he could use a moment to collect himself while I finish up with the mothers-to-be.”
The two nurses — both twenty-five, stunning, and very familiar with the Center’s most virile donors — smiled knowingly. Lena was a curvaceous brunette with massive, heavy tits that strained against her scrubs. Claire was a fiery redhead with equally impressive breasts and a wicked glint in her eye.
“Of course,” Lena purred, taking Ethan’s arm gently but firmly. “Come with us, sweetheart. We’ll take excellent care of you.”
The moment the door to the private aftercare suite clicked shut behind them, the two nurses’ professional masks shattered completely.
Lena, the curvaceous brunette with massive, heavy tits straining against her pale blue scrubs, dropped to her knees with a hungry moan. Her eyes widened in genuine awe as she yanked Ethan’s shorts down, letting his enormous ten-inch cock spring free like a thick, veiny club.
“Oh my fucking god...” Lena breathed, voice husky and dripping with lust. “Look at this absolute monster. No wonder you were about to explode back there, baby.”
Claire, the fiery redhead with equally enormous breasts and a wicked, predatory gleam in her eye, pressed herself against Ethan’s side. She ran her soft hand down his sculpted abs, then wrapped her fingers around the thick base of his throbbing shaft, giving it a firm, appreciative squeeze.
“He’s so fucking thick,” Claire moaned, slowly stroking him. “And so hard already ... poor thing. All that hot, potent cum just begging to be drained.”
Lena leaned in closer, her warm breath ghosting teasingly over the swollen, leaking head of Ethan’s cock. “Wait ... Lena, you know who this is, right?” Claire said suddenly, her eyes sparkling with filthy recognition. “This stud right here is Donor #347.”
Lena’s eyes widened dramatically, her full lips parting in shock and delight. She looked up at Ethan with fresh hunger.
“No way ... Are you serious?” she asked, voice dropping into a breathy whisper.
Claire nodded, still slowly stroking the thick base of his shaft with one hand. “I’ve checked him in a few times when he came to make donations. Trust me. This is the one everyone’s been whispering about in the break room.”
Lena let out a long, filthy little moan of pure excitement, her massive tits heaving as she stared at the throbbing monster in front of her. “Fuck ... no wonder you’re leaking so much. The famous #347...”
She turned her gaze up to Ethan’s flushed face, her expression turning even more predatory.
“So ... is Claire right?” Lena asked, giving his fat cockhead a slow, wet lick. “You really are Donor #347?”
Ethan swallowed hard, breathing raggedly. “Y-yeah ... I am.”
Lena’s eyes darkened with lust. She glanced back at Claire, then up at him again, her voice turning low and wicked.
“Wait ... I think I heard right earlier. When Mara asked if you were the father ... your mom said the other two were your sisters?” She licked her lips slowly. “Did you really knock up your own mom and both your sisters?”
Ethan’s cock jerked hard in Claire’s hand, a thick bead of precum oozing from the slit. He hesitated for half a second, then told the truth.
“Well ... not exactly how you think,” he admitted, voice rough. “They went to the Center. They all chose me as the donor without knowing it was me. But yeah ... they’re all carrying my babies.”
The two nurses froze for a heartbeat.
Then both of them moaned loudly, visibly aroused by the revelation.
“Oh my fucking god,” Lena whispered, her voice dripping with heat. “That is so fucking hot.”
Claire’s hand tightened around his thick shaft, stroking him faster. “You knocked up your own mother? And your sisters? With this fat, potent cock?”
Lena leaned in and sucked the leaking head into her mouth with a wet, greedy slurp, moaning loudly around him before pulling off with a pop.
“That’s the hottest thing I’ve ever heard,” she breathed, eyes glazed with lust. “I don’t just want to suck this cock anymore ... I need you to fuck me. I need to feel what your mom and sisters felt.”
Claire nodded eagerly, already pulling her scrubs down over her hips. “Same. I want this breeding cock inside me. Right now.”
Both nurses attacked him with pure, worshipful hunger.
They worked his massive cock together like it was their favorite toy — licking, sucking, and kissing every thick, veiny inch with sloppy, shameless enthusiasm. The two nurses were completely lost in lust, moaning and whimpering as they worshipped him.
