Early evening settled over the Thompson farmhouse like a warm, golden embrace. The long June day was finally softening into dusk, painting the orchards in deep amber and rose as the sun dipped toward the horizon. Inside, the house was unusually quiet — a rare and welcome stillness.
Sophia and Sloan had driven into downtown Kinridge for a date night, eager for some time alone amid the bustling energy of the revitalized west side. Ethan was still out in the fields, tending to a temperamental piece of irrigation equipment that had been acting up all afternoon. Isabella had disappeared up into his barn loft earlier, where Kaylee had come over for another “hangout” that would likely turn into much more.
For once, the sprawling farmhouse belonged entirely to Elizabeth.
She had spent the past hour in the kitchen preparing a quiet, intimate dinner for Marcus — roasted herb chicken, fresh vegetables from the garden, and warm bread. The scents still lingered pleasantly in the air as she moved upstairs, a soft, anticipatory smile on her lips. She wanted tonight to be special for him. A relaxing bath, soft lighting, maybe some of that wine he liked. Just the two of them, celebrating this new period in their marriage.
Elizabeth slipped into the master bedroom and let the silk robe slide from her shoulders, pooling at her feet. She stood naked in front of the tall, full-length mirror, the warm evening light pouring through the windows and bathing her body in a gentle, flattering glow.
She paused.
Her hands moved slowly, almost reverently, over her changing form.
At just seven weeks, the differences were still subtle ... but to her, they felt profound. Her breasts were noticeably fuller, heavier, the nipples darker and far more sensitive. Even the lightest brush of air made them tighten into stiff peaks. She cupped them gently, thumbs grazing the darkened buds, and a soft sigh escaped her lips as a warm pulse of arousal bloomed low in her belly.
Lower still, her abdomen showed the faintest, softest rounding — not yet a true bump, but a gentle warmth and fullness that made her instinctively rest both hands there. She rubbed slow, loving circles over the spot where her baby was growing.
It’s only been seven weeks ... she thought, eyes half-lidded as she studied herself. And yet this pregnancy already feels so much stronger than the others. More alive. More right.
Her mind, as it had done so often lately, drifted to him.
Donor #347.
The man whose potent seed had taken root so quickly and completely inside her after more than sixteen years. The thought sent a fresh, guilty throb straight through her core, deep and insistent, making her pussy clench with sudden need. She pressed her smooth thighs together tightly, feeling the warm, slippery evidence of her arousal already coating her folds and beginning to slick the insides of her thighs.
He must be so incredibly virile ... she mused, her breath catching as one hand trailed slowly downward, fingers brushing over the gentle, warm swell just above her mound. To have gotten not just me, but Sophia and Isabella pregnant so easily ... all three of us in such a short time.
A dangerous new thought slipped into her mind, unbidden and filthy.
I wonder ... how many more women are pregnant by him right now? How many more wombs has he filled without them ever stepping foot in the Legacy Center?
A hot flush raced across Elizabeth’s cheeks and down her chest. Her nipples tightened into aching peaks as fresh wetness pulsed between her legs. She tried — she really tried — to push the thought away. She had a wonderful husband. A loving, stable marriage. A beautiful family. This baby was a gift.
But the fascination refused to fade. If anything, it only grew stronger.
What kind of man could produce seed so powerful, so overwhelmingly fertile? What would it feel like to be taken by someone like that — raw, deep, and relentless? To be claimed and filled by a cock and balls capable of breeding multiple women so effortlessly?
Who was he?
Elizabeth shook her head slightly, a small, private, and undeniably aroused smile curving her lips as she continued caressing her softly changing body in the golden evening light. Her fingers lingered on her belly, gently rubbing the place where his potent gift was already growing inside her.
She had planned a romantic, tender evening for Marcus ... but standing here, admiring the early signs of the life growing inside her, she couldn’t quite silence the deeper, hungrier curiosity stirring within.
Elizabeth stood fully naked in the warm evening light, her skin flushed with a mix of anticipation and growing arousal. She began filling the large clawfoot tub with steaming water, adding a generous pour of her favorite vanilla-scented bubble bath. The rich, sweet fragrance filled the air as thick clouds of bubbles rose, the warm water releasing gentle wisps of steam that curled lazily toward the ceiling.
But her mind refused to stay quiet. The more Elizabeth tried to push the thoughts away, the stronger it became — and the wetter her pussy grew. A slick, needy heat throbbed between her thighs, her inner walls clenching around nothing as fresh arousal dripped slowly down her skin.
She couldn’t resist any longer.
Before stepping into the tub, Elizabeth opened the discreet drawer in the bathroom vanity and retrieved her new favorite toy — the full-scale, custom-molded replica of Donor #347’s cock that Sloan had proudly gifted each of them. The heavy, realistic silicone shaft felt substantial and warm in her hand, thick veins running along its impressive ten-inch length, the fat, flared head already glistening slightly from the lube she’d applied earlier. The 70% version the Center provided now felt like nothing more than a teasing appetizer compared to this.
Elizabeth slipped into the hot, bubbly water with a soft sigh of pleasure, the warmth enveloping her body like a lover’s embrace. She leaned back against the tub, spreading her legs beneath the fragrant bubbles, and slowly guided the massive dildo between her thighs.
The thick head pressed against her slick entrance and sank inside her with one smooth, deliberate push.
“Ohhh ... fuck...” she moaned softly, eyes fluttering shut as her pussy stretched beautifully around the realistic girth. It felt so good — so full — pressing against all the right places deep inside her.
She began moving it slowly at first, savoring every thick inch as she worked it deeper. Her free hand cupped one heavy, sensitive breast, rolling the darkened nipple between her fingers while her hips rocked gently, fucking herself on the donor’s perfect cock.
The thoughts only grew filthier.
He must be so strong ... so virile ... she thought, thrusting the dildo harder, faster. His cock feels so good. I wish I could feel the real...
Her first orgasm hit her suddenly, crashing over her like a powerful, unexpected wave.
Elizabeth’s back arched sharply out of the bubbly water, her full, sensitive breasts thrusting upward as her head fell back against the edge of the tub. A deep, throaty moan tore from her lips — low and needy at first, quickly rising into a long, trembling cry of pure pleasure.
“Ohhh ... god—!”
Her pussy clenched violently around the thick, realistic shaft buried deep inside her, rhythmic, powerful contractions milking the massive dildo as if trying to draw every drop of seed from it. The intense fluttering of her inner walls sent fresh ripples of ecstasy radiating through her core. Warm bathwater sloshed violently over the edges of the tub, splashing onto the tiled floor as her hips bucked and rolled uncontrollably, fucking herself deeper onto the thick cock with every spasm.
“Yes ... yes...” she gasped, voice husky and broken. One hand gripped the thick silicone base, holding it firmly in place while her other hand squeezed her heavy breast, pinching the dark, aching nipple hard. The combination of sensations — the deep, stretching fullness inside her, the warm water caressing her skin, the sweet vanilla scent filling her lungs — pushed her even higher.
In her mind, it wasn’t the toy anymore.
It was him.
Donor #347.
The virile, potent stud whose seed had already taken root so easily inside her. She imagined his thick, real cock pulsing deep in her womb, flooding her with hot, heavy ropes of cum, breeding her properly like the powerful man he clearly was.
The fantasy sent her spiraling.
Her second, stronger wave followed right on the heels of the first. Elizabeth’s entire body seized up, thighs trembling violently beneath the water as another guttural, throaty moan spilled from her open mouth. Her pussy gushed around the thick shaft, fresh slickness mixing with the bathwater as powerful contractions squeezed and fluttered without mercy.
She came hard — long, rolling, body-shaking waves that left her gasping and whimpering, hips jerking erratically as she rode out every last pulse of pleasure on the donor’s perfect cock.
By the time the orgasm finally began to ebb, Elizabeth was panting heavily, flushed from her chest to her cheeks, her body glowing with a fresh sheen of sweat and bathwater. A soft, satisfied, slightly dazed smile played across her lips as she slowly came back down, the thick dildo still buried deep inside her fluttering pussy.
She didn’t stop.
The second climax came faster, crashing into her with even greater intensity.
Elizabeth’s hips bucked wildly beneath the warm, vanilla-scented water as she drove the massive dildo deeper into her aching pussy with desperate, frantic strokes. Her legs trembled violently, thighs quivering uncontrollably as she fucked herself harder, chasing that perfect, devastating angle.
“Oh god ... oh fuck...” she whimpered, voice growing hoarse.
In her mind, it was no longer just a toy.
It was him — Donor #347. That virile, potent stud with his thick, ten-inch cock stretching her wide open, claiming her womb with deep, powerful thrusts. She imagined how heavy and hot the real thing would feel, how much thicker it would stretch her, how relentlessly it would breed her, flooding her with load after thick, fertile load until her belly swelled with his child.
The filthy fantasy pushed her right over the edge.
A sharp, throaty cry tore from her lips as the orgasm detonated inside her.
“Marcus!” she moaned loudly, his name spilling out like a guilty prayer even as the vision of the anonymous donor fucking her senseless burned behind her closed eyes.
Her back arched hard, breasts thrusting out of the bubbly water as her pussy clamped down like a vice around the thick silicone shaft. Powerful, rhythmic contractions ripped through her core, each one stronger than the last. Fresh, hot slickness gushed around the dildo, mixing with the bathwater as her body shook with overwhelming pleasure. Her legs kicked and trembled, sending more water splashing over the edge of the tub while she continued fucking herself through the shattering climax, hips jerking erratically.
“Marcus ... oh god, Marcus...” she gasped again, the name both an anchor and a confession as wave after wave of intense, guilty pleasure flooded through her.
Even as she came harder than she had in years, part of her mind stayed locked on the donor — on how his cock would feel breeding her so much deeper, so much more completely.
By the time the third powerful orgasm crashed through her, Elizabeth was a trembling, desperate mess of pleasure.
She was gasping sharply, whimpering helplessly with every breath, her chest heaving as warm water sloshed violently around her. One hand gripped the slick edge of the tub so tightly her knuckles turned white, trying to anchor herself against the overwhelming sensations. Her other hand moved frantically between her spread thighs, driving the massive, thick dildo in and out of her fluttering, greedy cunt with deep, relentless strokes.
The thoughts in her head were spiraling, filthy, and completely out of control.
Marcus ... she thought at first, clinging to the image of her loving husband. But the fantasy quickly shifted, growing hotter, darker, more dangerous.
The donor ... That virile, anonymous stud with his perfect, potent cock. The man who had already filled her so easily. She imagined him thrusting into her instead — thick, heavy, and relentless.
Then it blurred further. Different celebrities. Strong, handsome men she had seen in passing. But each fantasy only fed the fire until, without warning, the image changed completely.
Oh god ... Ethan!
The name tore from her lips in a raw, broken cry the instant his face and body fully formed in her mind. The taboo realization hit her like a lightning strike — her own son, the boy she had raised, the young man she was so proud of — and it shattered something deep inside her.
The orgasm that followed was life-altering.
Elizabeth’s entire body seized violently. A piercing, throat-tearing scream ripped out of her as the most intense climax of her life detonated deep in her core. Her back arched so sharply she nearly lifted out of the water, breasts heaving, dark nipples rock-hard and aching. Her legs kicked and trembled uncontrollably, splashing water everywhere as her pussy clamped down like a vice around the thick dildo.
