Elizabeth woke slowly as the early morning sun streamed through the large windows of the master bedroom, painting the room in soft golden light. She stretched languidly, a radiant smile spreading across her face as she remembered the news from last night.

She was pregnant.

Her hand drifted lovingly over her still-flat stomach as she rose from bed. Marcus was already in the shower, the sound of running water echoing from the bathroom. Feeling light and playful, she slipped into her favorite lacy white teddy — the one that barely reached the tops of her thighs and clung deliciously to her full breasts — before heading downstairs to make coffee.

As she passed the kids’ rooms, she noticed both beds were empty. That was normal for Ethan — he often crashed in his barn loft after long days. But Isabella’s bed was also untouched.

“Ethan?” she called out softly, not wanting to wake the whole house.

No answer.

She picked up the old house phone in the hallway and dialed the extension to the barn loft.

Up in the loft, the phone rang three times.

Ethan groaned, still half-asleep, his powerful body stretching lazily. He felt something incredibly warm and tight wrapped around his cock. Without thinking, he thrust his hips forward, pushing deeper into the silky, wet heat as he reached over and grabbed the phone.

“Uh ... hello?” he mumbled, voice deep and rough with sleep.

“Ethan, sweetie,” Elizabeth’s warm voice came through. “Is your sister with you?”

Ethan blinked slowly, still not fully awake. He groaned again and stretched, instinctively rolling his hips and driving his thick cock even deeper into the incredibly tight cunt gripping him. He finally looked down.

Isabella was spooned tightly against him, completely impaled on his morning-hard cock.

“Yeah, Mom ... she’s here,” he said, voice still heavy with sleep. “Must have crawled into my bed while I was asleep.”

“Aww,” Elizabeth cooed warmly on the other end. “She hasn’t done that since you two were little. Guess her being pregnant made her need her little brother for some emotional comfort. That’s so sweet.”

Ethan was much more awake now.

The realization hit him like a drug — his naked big sister, pregnant with his baby, was wrapped around his cock, her tight pussy stretched obscenely around his thick shaft. The thought made his cock throb violently inside her.

He started moving — slow, tender rolls of his hips, gently fucking her while still on the phone with their mother.

“Yeah ... she seemed pretty emotional last night,” he murmured, keeping his voice steady as he slid in and out of Isabella’s soaked pussy with long, luxurious strokes.

Isabella’s eyes fluttered open. For a split second she looked confused, then her face twisted in shock and overwhelming pleasure as she realized her little brother’s massive cock was buried balls-deep inside her.

She bit her lip hard, struggling to stay quiet while Ethan slowly wrecked her pussy with those deep, loving thrusts. Her hand flew up to cover her mouth as a muffled whimper escaped her.

Ethan smiled against her neck, still talking casually to their mom.

Ethan kept his slow, deep rhythm as he spoke to his mother, his thick cock sliding in and out of Isabella’s impossibly tight, soaking pussy with long, luxurious strokes.

“Yeah, Mom ... she was pretty emotional last night, we all were.” he said casually, voice low and slightly husky. He rolled his hips forward, burying every inch of his fat 10-inch cock into his sister’s clenching heat. Isabella’s eyes rolled back, her face buried deep in his pillow to muffle the desperate moan that tried to escape.

Elizabeth’s voice was warm and affectionate on the line. “Poor thing. With everything that happened yesterday ... the three of us all pregnant at once ... it’s a lot. I’m glad she went to you. You’ve always been her safe place.”

Ethan smiled, thrusting a little deeper. “Mmm ... yeah. I’ve got her.” His free hand slid up Isabella’s body, cupping one of her breasts and pinching her stiff nipple as he ground against her ass.

Isabella whimpered into the pillow, her pussy spasming hard around him. She came suddenly — a silent, shaking orgasm that made her toes curl and her walls flutter wildly around his cock.

Ethan continued talking like nothing was happening. “So ... how are you feeling this morning? Still glowing?”

Elizabeth laughed softly. “I feel wonderful, actually. A little nauseous, but mostly just ... happy. Excited. Like the whole house feels different now.”

He changed positions smoothly, rolling Isabella onto her stomach without pulling out. He mounted her from behind, pressing her down into the mattress as he started fucking her with deeper, more powerful strokes. The wet, obscene sound of his heavy balls slapping against her soaked pussy filled the loft.

Isabella grabbed the pillow with both hands and screamed into it as another orgasm tore through her.

“Sounds like you’re in a good mood,” Ethan said, voice only slightly strained as he railed his sister. “That’s good. We’re all going to need that energy with three babies coming.”

Elizabeth sighed happily. “Exactly. I was thinking ... maybe we should convert the guest wing sooner rather than later. Sophia and Sloan could move in after the term ends. We could raise them all together as one big family. What do you think?”

Ethan groaned quietly, the sound barely masked as he adjusted again. He pulled Isabella up onto her hands and knees, gripping her hips as he started fucking her harder, his thick cock plunging deep with every thrust.

“I think ... fuck ... that sounds perfect, Mom,” he managed, breathing heavier now. “The more the merrier.”

“You sound a little weird, sweetie. Everything okay?” Elizabeth asked, concern creeping into her voice.

Ethan clenched his jaw, slamming deep into Isabella’s spasming cunt as she came again, her whole body shaking violently.

“Yeah, I’m fine,” he grunted. “Just ... you know how it is when there is some in your bed ... I slept in a weird position. Got some deep kinks I need to stretch out real bad. I just ... well I know its gonna be loud.”

“Oh son, go ahead and be loud then,” Elizabeth said warmly. “Stretch it out. Don’t let me stop you.”

The permission hit him like a trigger.

At that exact moment, Ethan roared.

“Oh gawd—! That’s so fucking good—!” he cried out, voice raw and loud as he slammed balls-deep into Isabella and started cumming hard. His thick cock pulsed violently, flooding her womb with massive, heavy ropes of hot cum. He kept thrusting through it, growling and groaning as he emptied himself completely inside his sister.

Isabella came harder than ever, her scream completely muffled by the pillow as her pussy milked every drop from his throbbing cock.

Ethan panted heavily for a few seconds, still buried to the hilt, before he managed to speak again.

“We’ll ... we’ll be up shortly, Mom,” he said, voice rough but trying to sound normal. “Just need to ... wake up properly.”

Elizabeth chuckled softly. “Take your time, honey. I’ll have coffee ready.”

As soon as the call ended, Ethan dropped the phone and collapsed over Isabella’s trembling body, his cock still buried deep inside her, twitching with the last spurts of his load.

Ethan held Isabella close, his powerful arms wrapped around her trembling body as she shook with aftershocks. Every small movement he made — every subtle shift of his hips, every throb of his thick cock still buried deep inside her — sent fresh waves of pleasure crashing through her.

Isabella was lost.

Soft, broken whimpers and moans spilled from her lips as another rolling orgasm rippled through her. Her pussy clenched and fluttered wildly around his massive shaft, milking him with rhythmic spasms. Ethan groaned deeply at the sensation, his arousal surging higher than he’d ever felt before.

“Fuck, Bella...” he whispered against her ear, voice rough with lust and wonder. “You keep cumming so hard on my cock...”

He couldn’t resist any longer.

Slowly, tenderly, he began to move — long, deep strokes that dragged his fat 10-inch cock almost all the way out before sliding back in to the hilt. His hips grew more forceful with each thrust, but he remained determinedly gentle, loving, almost reverent. His hands explored her body with open hunger — cupping her breasts, rolling her stiff nipples between his fingers, sliding down her stomach as if already imagining it swollen with his child.

His lips found her neck, kissing and sucking softly as he fucked her with slow, powerful rolls of his hips. Each deep thrust made her moan louder into the pillow, her body shaking uncontrollably as yet another orgasm tore through her.

“You feel so fucking good,” Ethan breathed, voice low and reverent against her skin. “So tight ... so wet for me ... I can’t believe I’m inside you.”

Isabella’s only response was a muffled, desperate cry as she came again, her pussy gushing around his thick cock. Her legs trembled violently, barely able to hold her up on all fours as Ethan continued making love to her — deep, steady, and relentless.

He pulled her upright against his chest, one arm wrapped around her waist while the other hand played with her clit, his hips still driving into her from behind. His breath was hot against her ear as he whispered filthy, loving things between thrusts.

“That’s it, Bella ... cum on your little brother’s cock again...”
