Filthy Desire

Chapter 5: My Best Friend's Older Brother

A week had passed, today Kimberly was on the private beach, she'd been there for about an hour and is still there laughing as she waded deeper into the water. The late afternoon sun caught the waves around her. From the living room she looked small and far away, completely absorbed in the ocean.

Allen stood behind Ember at the floor-to-ceiling glass, both of them watching her for a long moment in silence. His chest pressed lightly against Ember’s back. One of his hands rested on her hip, thumb stroking slow, deliberate circles under the hem of the oversized shirt she had thrown on earlier.

“She’s going to be out there a while,” he murmured against her ear, voice low.

Ember’s breath caught. She could already feel him hardening against her ass.

“We shouldn’t…” she started, but the words came out weak. Her body leaned back into him instead of pulling away.

Allen’s hand slid higher, under the shirt, cupping one of her heavy breasts and squeezing firmly. His other hand moved between her thighs, finding her already wet through the thin fabric of her panties. He rubbed her slowly, pressing two fingers against her c**t in firm circles while his mouth trailed down the side of her neck, teeth grazing.

“Tell me to stop then,” he said.

She didn’t.

He pushed the shirt up and over her head in one smooth motion, leaving her in only the panties. Those followed a second later, yanked down her legs and tossed aside. Ember stood completely naked in front of the glass while Allen stayed dressed in his shorts. The contrast made her pulse race. He freed his c**k—already thick, hard, and leaking at the tip—and rubbed the swollen head through her folds from behind, coating himself in her wetness.

“Hands on the glass,” he ordered.

She obeyed, palms flat against the cool surface. He kicked her feet farther apart, gripped her hips hard, and thrust into her in one deep, relentless stroke. Ember’s cheek and both full breasts pressed firmly against the window as a broken moan tore from her throat. Allen didn’t start slow. He f****d her with long, powerful strokes right away, the wet sound of his c**k driving into her filling the quiet living room.

Every thrust pushed her harder against the glass. Her n*****s dragged roughly across the smooth surface. From the beach, if Kimberly looked up at the right angle, she would see everything—her best friend naked and pinned, Allen’s hips slamming forward, Ember’s mouth open in raw pleasure.

The risk only made it hotter.

Allen’s hand slid around to rub her c**t in tight, almost rough circles while he pounded into her. “Look at you,” he growled against her ear. “Bent over for me where anyone could see. Taking my c**k like this.”

Ember moaned louder, forehead dropping against the glass. Her large breasts flattened and bounced with every hard thrust. Allen gripped one of them roughly, squeezing and rolling the n****e between his fingers as his c**k kept slamming deep. The stretch was intense; every stroke dragged against her walls and forced soft, helpless sounds out of her.

The first orgasm hit her fast and hard. Her p***y clamped down around him as she came, squirting around his c**k with a sharp cry. The hot rush of fluid spilled down her thighs and onto the floor. Allen didn’t slow. He f****d her straight through it, the wet sounds growing filthier, his grip on her hip bruising.

“That’s one,” he muttered against her neck, still thrusting deep. “Give me another.”

He pulled almost all the way out, then slammed back in harder, the force making her breasts smash against the window again. His fingers worked her swollen c**t faster and rougher. Ember’s second orgasm tore through her even harder. She screamed, body jerking, squirting again—messier this time—coating his c**k, his shorts, and the glass in front of her. Her legs shook so badly he had to lock an arm around her waist to keep her upright while he continued pounding into her.

Allen was breathing hard now, but he still didn’t ease up. He shifted the angle, f*****g her with short, brutal strokes that kept her completely stuffed full. One hand stayed on her c**t; the other pinned her hip firmly to the glass so she couldn’t escape the intensity.

“One more,” he ordered, voice rough. “Come on my c**k again.”

Ember’s third orgasm hit like a wave. Her whole body locked up, p***y convulsing wildly around him as she squirted a third time, uncontrolled and messy. The tight, pulsing heat finally broke Allen’s control. He buried himself to the hilt with a deep, guttural groan and came hard, flooding her with thick ropes of c*m until it started leaking out around his c**k and running down her thighs with every small grind of his hips.

He stayed deep inside her afterward, chest pressed to her bare back, both of them breathing heavily against the glass. Outside, Kimberly was still laughing in the water, completely oblivious.

Allen’s hand stroked slowly over Ember’s stomach, then lower, feeling where they were still joined and the thick mess he had made of her.

Neither of them moved for a long time.
