The click of the lock still hung in the air when Delphine turned to face him. She was twenty-eight, married three years, and walking into Henrik’s apartment the same afternoon Barrett’s plane left the ground felt like the most honest thing she had done in months. Barrett, thirty and already somewhere over the Midwest for a week of meetings, had kissed her temple at the curb and promised to call. She had smiled, watched the car pull away, and driven straight here.

Henrik was thirty-two, taller, broader through the shoulders, living-room light catching the dark stubble along his jaw. Brother-in-law. Her husband’s brother. The man she had been fucking, fully and eagerly, for the better part of a year—every time wanted, asked for, agreed to in the same hungry language they used now without speaking. He closed half the distance and stopped, waiting, because he always waited until she made it plain.

“I need to tell you something,” Delphine said.

“Then tell me.”

Her palm settled on the low, new curve of her stomach. Clothes still hid most of it. Her body did not. “I’m pregnant, Henrik. It’s yours. From us. From all those times I begged you to fill me and you did because I asked.” She watched his face the way a woman watches a match catch. “Barrett doesn’t know. He doesn’t need to know. I came here the minute he left because I wanted you to hear it first, from me, while we have the whole week.”

Henrik’s eyes dropped to her hand and stayed there long enough that heat crawled up her throat. When they lifted again they had gone dark, blown with a possessive pride so naked it made her thighs press together. Lust rode right behind it, raw and unhidden. He looked at her as if the baby, her body, the confession itself belonged in his hands.

“You’re carrying my child,” he said, not a question.

“Yes.”

“And you want me to know that while he’s gone.”

“I want you to celebrate it.” She swallowed. “I want you.”

He breathed out, a slow wrecked sound, and the tension in the room tightened until it hummed. She stepped between his knees when he sat back on the couch, took his wrists, and set his palms on her hips. He spread his fingers, thumbs stroking the place her body had already begun to change for him. A growl lived under his next breath.

“Delphine.” Her name sounded like ownership and worship at once. “Say it again.”

“I’m pregnant with your baby.” She guided one of his hands fully onto her belly. “Celebrate with me.”

He pulled her down by the waist and kissed her like a man starving. It was deep, hungry, all tongue and the scrape of stubble, his mouth opening hers until she moaned into it. His hands mapped her—ribs, the heavier swell of her breasts, the soft new roundness he kept returning to as if he needed to keep proving it was real. When he broke the kiss he stayed close enough that his words moved against her lips.

“I want to celebrate by worshipping every inch of this pregnant body,” he growled. “Your tits, your belly, that sweet cunt that’s already carrying me. I want my mouth on you until you shake. I want my cock in you after. Tell me you want that.”

“Yes.” She said it fast, no hesitation, fingers already in his hair. “I want it. I need it. Barrett’s gone a week and I have been aching since the tests came back. I need your mouth. I need your cock. I need you to make me come over and over until I can’t think.” She kissed him again, biting his lower lip. “Please. Celebrate with me.”

He made a sound that was almost a laugh and almost a groan. “Then get on the couch. Spread your legs for me.”

She did it eagerly, kicking off her shoes, shoving her skirt up her thighs, hooking her panties aside with two fingers because she did not want to wait to undress all the way. She sat back against the cushions, knees falling open, the wet gleam of her already obvious. Henrik dropped to his knees between them like a man taking communion. He looked at her pussy, then at the slight dome of her belly, then up at her face.

“You have no idea how badly I’ve wanted this,” he said. “You, full of me. You, asking me to ruin you while he’s away.” His palms slid up the insides of her thighs, spreading her wider. “Tell me again how much you need it.”

“I need your mouth on my clit,” she said, voice gone rough. “I need you to tongue-fuck this pregnant pussy until I come on your face. Then I need your cock. Pussy and ass, Henrik. I want all of it. I want to come until I scream. I asked for this. I’m asking now.”

He licked her.

It was not gentle. He dragged his tongue in a slow, filthy stripe from her entrance to her clit and sealed his mouth over her like he meant to live there. Delphine’s head fell back. One of his hands stayed on her thigh; the other splayed over her belly, possessive, warm, thumb stroking as he sucked. She threaded her fingers into his hair and held him there because he liked being held, because she liked the way he groaned into her when she pulled.

He circled her clit with the flat of his tongue, then the point, then sucked until her hips jerked. When she was shaking he pushed his tongue inside her, fucking her with it in deep, wet strokes, nose pressed to her clit, the wet sounds obscene in the quiet apartment. She was already close. Pregnancy had made her greedy, sensitive, a live wire. She told him so between broken breaths.

“Don’t stop—Henrik, I’m—your mouth, fuck, I’m going to come—”

He doubled down, two fingers sliding into her soaked pussy while his tongue worked her clit, and she broke with a cry that tore out of her chest. The first orgasm hit hard, rippling through her, her cunt clenching around his fingers, her belly tightening under his palm. He licked her through it, greedy, swallowing what she gave him, praising her in a low rasp against her folds.

“That’s one. Beautiful. Pregnant and coming on my tongue. Give me another when you’re ready. I’m not done celebrating.”

She was panting, dazed, still twitching when he stood, stripped, and manhandled her with her full, eager cooperation—turning her, bending her over the back of the couch so her chest met the cushions, ass up, belly supported, legs spread. She reached back and pulled her own cheeks apart for him, looking over her shoulder.

“Fuck me,” she said. “My pussy first. It’s yours. It’s been yours. Pound me until I come again.”

He notched the thick head of his cock against her and pushed in on one long, claiming stroke. She was soaked, open, still fluttering from the orgasm, and the stretch made her moan loud enough to startle herself. Henrik bottomed out and held, hands bracketing her hips, one sliding around to cup her belly again.

“Christ, Delphine. You’re dripping. Carrying my baby and still this greedy for my cock.” He pulled back and slammed in. “You asked for this. You came here and spread these legs. Take it.”

He fucked her. Hard, deep, the wet slap of his hips against her ass filling the room, the couch creaking. Every thrust shoved a sound out of her. He reached under, found her clit with two fingers, and rubbed in tight circles while he pounded her from behind. She came apart the second time with his name in her mouth, pussy spasming around his thick cock, vision going white at the edges. He fucked her through that one too, slowing only enough to keep her on the hook, not enough to let her down.

“Again,” he said against her spine. “You said multiple. You said you needed it. I’m going to put my cock in this ass next, and you’re going to come on it. You want that. Say it.”

“I want it,” she gasped, wrecked and shining with sweat. “I want your cock in my ass. I want you to fill me. Please, Henrik—celebrate. Use me. I asked. I’m asking.”

He pulled out of her pussy with a filthy sound, gathered her wetness on his fingers and his cock, and pressed the slick head to her tight hole. She pushed back onto him, moaning at the burn, the stretch, the slow inexorable slide as he fed her his cock an inch at a time. When his hips finally met her ass she was shaking, full, stuffed, one hand under herself on her clit without being told.

“That’s it. Take all of it. Pregnant wife bent over my couch with my cock in her ass while her husband is on a plane.” He started to thrust, short and deep at first, then longer, grinding into her. “You wanted this celebration. You wanted my mouth and my cock in both holes. Come for me. Come while I’m in this tight ass.”

He reached around and took over on her clit, rubbing firm and fast while he fucked her ass with a rhythm that punched the air out of her. The third orgasm detonated without warning—she screamed into the cushion, whole body locking, ass clenching around his cock so hard he cursed. He did not stop. He kept thrusting, kept rubbing, chasing the oversensitive edge with her until the fourth one ripped through on the heels of the third, longer, shattering, her voice gone hoarse as she begged.

“Fill me—Henrik, come in my ass, I want every drop, please, it’s yours, the baby’s yours, this is yours—give it to me—”

He slammed deep and came with a groan that sounded pulled from the floor of him, cock pulsing, flooding her ass with thick heat. She felt every spurt. She pushed back to take it, moaning, greedy, thanking him in broken fragments while he emptied himself inside her. He stayed buried, grinding through the last of it, hand still cupping her belly as if to hold the whole filthy miracle in place.

When he finally eased out she made a small wrecked noise. Cum slipped from her ass down the insides of her thighs. He gathered her before her knees could fail, sat on the couch, and pulled her into his lap, her back to his chest, his spent cock soft against her hip, both of them breathing like they had run.

He stroked her belly with slow, gentle passes of his palm. She caught her breath in pieces, then turned her head and kissed him lazily, unhurried, tasting herself on his mouth. His other arm banded around her, not tight, just there. They smiled at the same time, small and knowing.

The week stretched in front of them, Barrett gone, the apartment theirs, the secret living only in this room and in her body. This was the first. There would be more. Mouth, cock, pussy, ass—every way they had already agreed to celebrate the baby only they knew was Henrik’s.

Late light moved across the floor. Neither of them spoke. His hand rested quiet on her stomach. Her head rested quiet on his shoulder. The room held the silence.
