New Neighbors Invite Us to Join Their Window Sex

The boxes were still stacked along the far wall when Nathaniel killed the overhead light. Twenty-two and sore from a day of hauling furniture up three flights, he wanted only the dark and the narrow slice of night beyond the glass. Their new apartment faced a courtyard so tight he could have tossed a pillow and hit the opposite windowsill. Brigitte, twenty-one, stood barefoot beside him in an old T-shirt and cotton panties, one hand on the sill, watching the building across the way light up room by room.

Most of the windows were dark. One wasn't.

They had seen the names that afternoon on a mailbox still taped with a moving label: Mateo and Elise, the couple who had taken the unit directly opposite. Twenty-four and twenty-three, the building manager had said, easy and good-looking, the kind of neighbors you waved to on the stairs. Nathaniel had not expected to meet them like this.

Curtains hung open on a wide rectangle of warm light. Inside it, Mateo and Elise were already half undressed, moving against each other with the careless heat of people who had forgotten the rest of the city existed. Nathaniel felt Brigitte go still. He felt it in his own chest too, a sudden tight awareness that made the sore muscles in his shoulders irrelevant.

Mateo was broad through the shoulders, dark hair pushed back off his face, pants shoved low on his hips. Elise's long hair spilled down her bare back, her skin flushed under the lamp, her bra already gone. They kissed like they meant to use every inch of the mattress. His hands slid over the curve of her ass, and she laughed against his mouth before he turned her and pressed her palms to the glass.

Nathaniel's mouth went dry. "They're not closing anything."

"I know." Brigitte's voice was small and bright at once. She didn't step back. Neither did he. From the shadowed bedroom they could see everything the lamp showed: Mateo's mouth on Elise's neck, her hips rolling back into him, the unhurried way he lined himself up behind her. When he pushed in, her mouth opened on a sound they couldn't hear, and her fingers spread white against the pane.

Nathaniel's cock thickened against the seam of his pants. He shifted, caught for half a second between decency and hunger, and then hunger won, because Brigitte's breathing had gone shallow beside him and her thigh was pressed warm to his. Across the courtyard the couple fucked in full view, slow and then less slow, her breasts swaying, his hands gripping her hips hard enough that Nathaniel could imagine the marks. Elise turned her head, smiling over her shoulder, and Mateo answered with a deeper thrust that rocked her forward onto her toes.

"We should..." Brigitte started, and didn't finish. Her hand found Nathaniel's wrist. Her pulse raced under his fingers. They stayed where they were, two silhouettes in a darkened room, watching the uninhibited strangers lose themselves against the glass. Heat climbed Nathaniel's neck. Brigitte made a soft, involuntary sound and leaned into him, and he realized his own hand had settled low on her stomach, possessive without his meaning it to be. The sight held them the way a lit match holds a dark room. Their arousal built in the quiet between heartbeats, thick and undeniable, while Mateo and Elise kept going as if the night belonged only to them.

Elise's eyes found them first.

She was braced at the window, Mateo driving into her from behind, and for a moment Nathaniel thought the angle had only caught their reflections. Then her gaze sharpened. She looked straight across the narrow courtyard into the dark of their bedroom, and her mouth curved. She didn't flinch. She didn't reach for the curtain. She pushed her ass back harder onto Mateo's cock and lifted one hand from the glass in a small, unmistakable wave.

Mateo's head turned. He saw them too. Surprise crossed his face and then something warmer, something that looked a lot like pleasure at being watched. He slowed. The hard rhythm eased into long, deliberate strokes, each one meant to be seen. He slid a hand up Elise's body, cupped her breast, and rolled her nipple between his fingers while he fucked her in plain sight. Elise's lips parted. She held their gaze and let them watch every inch of him disappear into her.

Brigitte's fingers tightened on Nathaniel's wrist. "Oh my God."

"They see us." His voice came out rough.

"I know. Don't move."

He didn't. Neither did she. Color rose high on Brigitte's cheeks. Her nipples showed through the thin T-shirt, and when she shifted her weight he felt the restless press of her hip against his thigh. Across the way, Mateo bent Elise farther over the sill so the lamplight caught the wet shine where their bodies joined. He fucked her slowly enough that every thrust was a sentence. Elise reached back, spread herself with two fingers, and looked straight at the darkened window as if she were offering the view on purpose.

Nathaniel's cock ached. He was hard enough that the waistband of his pants hurt. Brigitte glanced down, saw it, and made a helpless little sound. Her hand left his wrist and settled, tentative, over the bulge. She didn't stroke yet. She just held him there, breathing fast, eyes flicking from his face to the couple in the light.

"You're shaking," he said.

"So are you."

Mateo pulled out, turned Elise, and lifted her onto the wide windowsill so her back met the glass and her legs opened toward the courtyard. He sank into her again, face to face, one hand braced beside her head. Her heels crossed behind his back. From across the gap Nathaniel could see the flex of Mateo's ass, the way Elise's breasts bounced with each thrust, the open, unashamed pleasure on her face. She pointed. Not at the sky. At them. Then she crooked two fingers in a clear come-here.

Mateo followed her gesture. He looked at Nathaniel and Brigitte, smiled, and repeated it, broader, an invitation with his whole arm. He mouthed something they couldn't hear and didn't need to. The meaning sat in the open curtains, in the slowed rhythm, in the way neither of them made any move to hide.

Brigitte's hand tightened on Nathaniel's cock through his pants. "They want us to come over."

"Yeah." His heart was a fist in his throat. He turned his head. In the faint spill of light from across the courtyard her eyes were wide, her mouth soft, her whole body flushed and restless against him. "Do you want to?"

She swallowed. For a second the old caution moved through her face, the part of her that had never done anything like this, that had only ever been his. Then she looked back at Elise, who was smiling even as Mateo fucked her against the glass, and the caution burned off.

"I want to," she said. "God, Nathaniel, I want to. First time for both of us. If you want it too."

He nodded before the sentence finished, eager and a little unsteady, the agreement already hot in his chest. "I want it. I want to go over there. I want to touch them. I want them to touch you. Only if you're sure."

"I'm sure." She rose onto her toes and kissed him, quick and hungry, tasting of nerves and yes. Across the courtyard Mateo slowed again, waiting, Elise's hand still lifted in that crooked invitation. Brigitte lifted her own hand and nodded, once, clear enough to read from the other side of the glass. Nathaniel did the same. Mateo's grin flashed. Elise blew them a kiss and pointed toward the building door.

They were already moving before either of them could talk themselves out of it.

The stairwell smelled like fresh paint and cardboard. They crossed the courtyard in the warm night air, barefoot urgency traded for shoes shoved on without socks, and Mateo met them at the apartment door in unbuttoned pants and nothing else, twenty-four and grinning, sweat shining on his chest. Elise stood just behind him in an open robe that hid nothing, twenty-three, flushed from fucking, her smile bright and a little breathless.

"You two are brave," Mateo said. "And gorgeous. Come in. Only if you still want to."

"We want to," Brigitte said, and Nathaniel heard the want in it, clean and adult and sure. "We've never done this. With anyone else. But we want to."

"Then we'll go slow where it matters and not where it doesn't." Elise took Brigitte's hand and drew her inside. The door shut. The big bed faced the same open window they had been watching through, curtains still wide, the darkened rectangle of their own bedroom visible across the gap. Lamplight made everything gold. "Names. I'm Elise. He's Mateo. You're the new couple. We saw the mailbox."

"Nathaniel. Brigitte." His voice barely held. "And yes. We were watching. We couldn't stop."

"Good," Mateo said. "We liked being watched. We'll like this better." He looked at both of them, steady. "Anything you don't want, you say so. We stop. Deal?"

"Deal," they said together.

Clothes came off fast after that. Brigitte's T-shirt hit the chair. Nathaniel's pants followed, his cock springing free, already wet at the tip. Elise let the robe slide from her shoulders and stood naked, full breasts tipped with dark nipples, the slick shine of Mateo still on her inner thighs. Mateo shoved his pants down and off. He was thick, heavy, and unashamed about the way Brigitte's eyes caught on him. She flushed darker and didn't look away. Elise's gaze traveled Nathaniel's body with open appreciation, and when she stepped in and kissed him, soft at first and then deeper, he groaned into her mouth and felt the last of his hesitation burn away.

They paired without ceremony and then stopped pretending the pairs were fixed.

Elise guided Brigitte onto the bed and spread her thighs with careful hands. "May I?"

"Yes," Brigitte whispered. "Please."

Elise lowered her mouth and licked a slow, wet stripe up Brigitte's pussy, and Brigitte's back arched off the sheets. Nathaniel stood at the foot of the bed, stunned by the sight of another woman's tongue on his girlfriend, by the way Brigitte's fingers tangled in Elise's hair and held her there. Mateo came up behind Elise, kissed her shoulder, and looked at Nathaniel.

"She wants you in her while she does that. If you want her."

"I want her." Nathaniel's hands were already on Elise's hips. She pushed her ass back in answer, still licking, and he lined his cock up with her soaked entrance and pushed in. Heat closed around him, tight and slick and shocking. Elise moaned into Brigitte's pussy, the sound vibrating, and Brigitte cried out at the ceiling. Nathaniel fucked Elise from behind in long, deep strokes, watching his cock disappear into her, watching her mouth work Brigitte open. Elise ate her like she was starving, tongue flat and then pointed, lips sealed around Brigitte's clit, two fingers sliding in beside the lick when Brigitte begged for more.

"Oh God, oh God, she's—Nathaniel, she's so good—" Brigitte's thighs shook. Her eyes found his over Elise's back, wild and grateful and wrecked, and the look went straight to his balls. He gripped Elise's hips harder and drove in, the wet slap of it filling the room. Elise took every thrust and gave it back as attention on Brigitte's clit, sucking, circling, moaning when he bottomed out. Mateo stood close, stroking himself slowly, watching his girlfriend get fucked while she made another woman fall apart, a smile on his mouth like this was exactly the welcome he had wanted to give.

Brigitte came first, sudden and loud, hips bucking against Elise's face, one hand fisted in the sheets. Elise didn't stop until the aftershocks eased. Then she lifted her head, chin shining, and looked back at Nathaniel. "Don't come yet. I want more of all of you."

He pulled out shaking, cock glistening, and Elise turned, kissed him filthy and deep so he tasted Brigitte on her tongue, and laughed when he groaned.

They switched without losing the heat.

Mateo climbed onto the bed and settled between Brigitte's still-trembling thighs. He rubbed the head of his cock through her wetness, slow, asking with his eyes. She nodded, breathless, and reached for him. "Yes. I want you inside me. Nathaniel, watch. I want you to watch."

"I'm right here," Nathaniel said, and he was, kneeling at the edge of the mattress, one hand on her hair.

Mateo pushed in. Brigitte's mouth fell open around a broken sound as he filled her, thicker than she was used to, and her hands flew to his shoulders. He fucked her in a deep, rolling missionary, chest to chest, kissing her when she tipped her face up, murmuring that she felt incredible, that she was taking him so well. Her legs wrapped his waist. Every thrust rocked the bed. Nathaniel watched his girlfriend get fucked by their new neighbor and felt no jealousy at all, only a blinding, grateful heat.

Elise dropped to her knees in front of him on the rug. "My turn to be messy." She took his cock in one hand, still slick from her own pussy, and swallowed him down in a sloppy, eager stroke. Spit spilled over her lip and down his shaft. She gagged softly, pulled off, spit again, and went back, noisy and wet, tongue swirling, hand twisting at the base. The sounds were obscene. Nathaniel's head tipped back. He looked down and saw Elise's eyes on him, watering and pleased, and past her he saw Mateo driving into Brigitte, saw Brigitte's breasts bounce, saw her reach blindly until her fingers found his thigh and held on while another man fucked her.

"You look so good," he told her, voice wrecked. "Both of you. Jesus, Elise—"

Elise hummed around him and took him deeper, sloppy strings of spit connecting her mouth to his cock when she pulled back to breathe. Mateo shifted his angle, hit something that made Brigitte sob his name and then Nathaniel's, and Nathaniel had to fist a hand in Elise's hair and ease her off before he finished on her tongue.

"Not yet," he managed. "I want what comes next. All of it."

Elise wiped her mouth with the back of her hand and grinned. "Then stand up, both of you. Side by side. We had an idea while you were fucking us."

Mateo pulled out of Brigitte with a groan, kissed her once more, and climbed off the bed. The two men stood together at the foot of it, cocks heavy and shining, close enough that their shoulders brushed. Brigitte and Elise slid off the mattress and knelt on the rug in front of them, naked, flushed, hair mussed, looking up with the same hungry light.

"Swap," Elise said, and leaned in to take Mateo while Brigitte wrapped her mouth around Nathaniel.

They didn't stay put. Brigitte sucked Nathaniel with shy determination that turned filthy fast, learning the taste of Elise still on him, hollowing her cheeks, letting spit run down his length the way she had just watched. Elise deep-throated Mateo with practiced ease, then pulled off and turned her head, and the women traded. Brigitte's lips stretched around Mateo's thicker cock. She moaned at the weight of him, took what she could, and stroked the rest while Elise swallowed Nathaniel again, messier than before, gagging happily, pulling off to lick both of them in one greedy pass when the men shifted closer.

They swapped and swapped. Mouths crossed. Hands overlapped. Elise held Mateo's cock and Nathaniel's together for a moment and licked up the seam between them while Brigitte kissed her, open and wet, sharing the taste. Then Brigitte took Mateo deep enough to tear up, and Elise guided her, murmuring encouragement, before they switched again and Brigitte was back on Nathaniel, sloppy and devoted, while Elise worked Mateo with her throat. The men stood shoulder to shoulder, groaning, hands in hair, watching two beautiful women kneel and trade their cocks like a game they had invented and already loved. Spit shone on chins, on shafts, on the rug. Brigitte looked up at Nathaniel with Mateo's cock in her mouth and pure, astonished joy in her eyes, and he nearly lost it.

"Bed," Mateo said, rough. "If I stay here I'm done. I want to watch you ride him. Elise, I want you on me where they can see."

They climbed up together. Nathaniel lay back against the pillows. Brigitte swung a leg over him, facing the foot of the bed, and sank down onto his cock in one slow, shaking slide. Reverse cowgirl. Her ass settled against his hips, her back a long beautiful line, and she braced her hands on his thighs and started to move. Across the mattress Mateo stretched out the same way. Elise straddled him facing away, took him deep, and looked straight at Brigitte while she did it.

They rode in view of each other, perfect and unhidden.

Brigitte's ass bounced as she found a rhythm, Nathaniel's cock sliding in and out of her soaked pussy, the wet sound of it mixing with Elise's. Elise rolled her hips in a filthy circle, hands on Mateo's knees, breasts swaying, eyes locked on Brigitte's face. The women watched each other take it. They watched the way each cock disappeared, the way each mouth fell open, the way sweat gathered at the small of a back and ran. Nathaniel gripped Brigitte's hips and thrust up to meet her. Mateo did the same for Elise. The bed shook. The open window poured night air over their hot skin, and none of them reached for a curtain.

"Look at you," Elise panted, riding harder. "Look at how you take him. God, you're beautiful."

"So are you," Brigitte gasped. "I can see him in you. I can see all of it. Nathaniel, don't stop, I'm close, I'm so close—"

"Come on me," he said, and fucked up into her while she ground down, ass slapping his hips, her pussy clenching in tight, helpless pulses. She came with a cry that cracked in the middle, loud and shameless, thighs shaking, and the squeeze of her dragged him right to the edge. He held on by his teeth.

Elise was right behind her. She slammed down onto Mateo, circled, and broke apart with a long, raw moan, one hand flying back to grip his wrist. Mateo swore, hips jerking. "Inside?" he managed.

"Yes," Elise said. "Yes, come in me."

He did, groaning, spilling deep while she rode the aftershocks. The sight undid Nathaniel. He warned Brigitte in a wrecked voice and she bore down harder, answering yes, yes, fill me, and he came in thick pulses, buried in his girlfriend while their new neighbors shook through their own finish a few feet away. Elise leaned over and kissed Brigitte through it, messy and sweet, both of them still seated on the cocks that had just emptied inside them, sweat shining, laughter already breaking through the moans.

They didn't stop at one crest. Hands wandered while they were still joined. Mateo reached across and thumbed Brigitte's clit until she clenched and came again, smaller and sharper, milking the last of Nathaniel's orgasm into a second helpless spurt. Elise ground down and pulled another groan out of Mateo, then slid off him, crawled between Brigitte's thighs, and licked Nathaniel's come from her while Brigitte sobbed and clutched the sheets. Nathaniel sat up, kissed Elise's shoulder, and stroked Mateo through the oversensitive twitches until all four of them were gasping, laughing, and finally, finally still.

The room smelled like sex and warm skin. The curtains had never moved.

They ended in a tangle on the wide bed, limbs overlapping, the sheet kicked to the floor. Brigitte lay half across Nathaniel's chest with Elise's head on her stomach, and Mateo's arm was thrown over all of them, heavy and easy. Lazy kisses passed wherever mouths could reach: Nathaniel to Brigitte's hair, Brigitte to Elise's temple, Elise turning to catch Mateo's mouth, Mateo leaning over to kiss Nathaniel once, brief and smiling, like a seal on the night. Soft laughter kept breaking out whenever someone shifted and found a wet spot or a stuck thigh.

"So," Elise said, tracing a finger along Brigitte's hip, "the curtains stay open. That part isn't negotiable. I liked knowing you were there before I liked having you here, and I like having you here a lot."

"Agreed," Mateo said. "Any night the mood hits, you knock. Or we knock. Or we just start and wait to see if you wave back."

Brigitte hummed, sated and bright. "We'll wave back."

Nathaniel kissed the top of her head and stared at the dark rectangle of their own window across the courtyard, already turning the next time over in his mind. Not if. When. He could see it clearly: their bedroom light on, Brigitte bent over their sill the way Elise had been, his hands on her hips, the two of them fucking in full view until Mateo and Elise noticed and crossed the courtyard again. He would text them before they even got their clothes off. He would tell them to bring nothing but the want, and he would have Brigitte already wet and waiting at the glass, putting on the show this time, inviting the neighbors back for a longer night, a slower one, one where nobody left until morning.

He smiled into her hair, the plan already warm and certain behind his teeth, and didn't say it out loud yet. He would. Soon. The curtains across the way were still wide open, and he had no intention of ever closing theirs.
