Chapter 2: crossing the line.

My Best Friend’s Stepbrother

Riley stepped fully into the room and let the door close behind her with a soft click. The sound felt final. Irrevocable. Her bare feet sank into the carpet as she moved closer to the bed. Caleb's hand was still wrapped around his cock, but the strokes had slowed to almost nothing. He watched her approach with dark, unblinking eyes.

"What are you doing here?" he asked again, voice low and rough from the edge he was riding.

She stopped two feet from him. Close enough to smell the heat coming off his skin. "I heard you."

His grip tightened on his shaft. "You were supposed to be in Harper's room."

"I was."

"Then why are you standing in mine?"

Riley took one more step. "Because you said my name."

He exhaled sharply through his nose. "And?"

"You said my name while you were stroking your dick."

Caleb's hand stilled completely. "You think that gives you permission to walk in here?"

She met his gaze. "You know I can actually help you with that."

His eyes narrowed. "Harper."

"Harper is asleep already."

He let go of his cock. Stood up slowly. Towered over her. "This isn't right."

Riley tilted her head. "What isn't right?"

He stepped closer. "This. You. Here. While she's asleep down the hall."

Riley's voice dropped to a whisper. "You mentioning my name when you stroke your dick is what you call right?"

Caleb's jaw clenched. His cock twitched between them.

"Go back to your room," he said. "Pretend you didn't hear anything. Pretend you didn't see this."

She shook her head. "No."

She took one step forward.

Caleb's voice dropped to a warning growl. "Riley. If you walk any further, I can't promise what I'll do to you."

She took another step.

He exhaled hard. "You ask for it."

She kept walking.

When she reached him, their bodies were almost touching. She could feel the heat of his cock brushing her stomach through the thin sleep shirt. She looked up at him.

Caleb's control broke.

His hand shot to the back of her neck. Gripped hard. Tilted her face up. His mouth slammed down on hers. Hard. Hungry. Just raw need. Tongue forcing past her lips. Teeth clashing. He kissed her like he was punishing both of them.

Riley moaned into his mouth. Hands flew to his shoulders. Nails dug in deep. She kissed him back just as hard. Desperate. Years of pent-up want exploding between them.

He spun her around. Slammed her chest against the door. The wood rattled. One thick thigh shoved between her legs. Pressed right against her bare pussy. She gasped. Rocked forward instinctively. The friction made her whimper.

"You're fucking soaked," he growled against her ear. "All from hearing me jerk off to your name."

"Yes."

His hand slid under the shirt. Cupped her breast. Squeezed hard. Thumb flicked her nipple. Then pinched. Twisted. She cried out softly.

"Quiet," he snapped. "Harper's asleep."

She bit her lip. Nodded.

He yanked the shirt over her head. Threw it aside. Left her naked. Breasts heaving. Nipples hard and red from his finger.

He stepped back slightly. Looked down at her.

"On your knees."

Riley dropped instantly. Knees hitting the carpet. Face level with his cock.

"Open your mouth."

She parted her lips. Tongue out.

He gripped the base of his shaft. Fed the head past her lips. She closed around him. Sucked hard. Tongue swirling over the slit. Tasting the salt of pre-cum.

Caleb groaned low. Hand fisted in her hair. Pushed deeper.

"Take it."

She relaxed her throat. Took more. Gagged softly when he hit the back. He held her there. Let her adjust. Then started fucking her mouth. Slow at first. Then deeper. Faster. Balls brushing her chin.

Saliva poured from the corners of her mouth. Dripped down her chin. Down her breasts. She moaned around him. The vibration made his thighs tense.

"Such a good little mouth," he rasped. "Sucking your best friend's stepbrother like you've been dreaming about it."

She had.

He pulled out suddenly. Cock slick with her spit. Strings connecting her lips to the head.

Caleb hauled Riley up by her arms and threw her onto the bed. She landed on her back, legs falling open wide. Her pussy glistened under the faint hallway light slipping beneath the door. Still dripping from how wet she had gotten just from sucking him.

He climbed over her instantly. Knees shoving her thighs further apart. One hand pinned both her wrists above her head. The other guided his cock to her entrance. He rubbed the thick head through her folds once, coating himself in her slick heat.

"You want this?" he asked, voice low and dangerous.

Riley nodded fast. "Yes. Fuck me. Now."

He thrust in hard. One brutal stroke buried him to the root. Riley's back arched off the mattress. A choked cry escaped her lips before she bit it back. Her walls clamped down around him, fluttering wildly at the sudden fullness.

Caleb didn't wait. He started fucking her with deep, punishing thrusts. Each slam rocked her body forward. Tits bounced with the force. The wet slap of skin on skin filled the room, louder than their ragged breathing.

He released her wrists to grip her hips instead. Fingers dug in hard enough to bruise. He pulled her down onto his cock with every upward stroke, making sure she took every inch.

"So fucking tight," he growled against her neck. Teeth scraped her skin. "Been dreaming about this pussy squeezing me like this."

Riley wrapped her legs around his waist. Heels dug into his ass, urging him deeper. "Harder. Please. Ruin me."

He gave it to her. Hips snapping faster. Cock pistoning in and out. Hitting that spot inside her that made her eyes roll back. One hand slid between them. Thumb found her clit and rubbed fast, rough circles.

Her moans turned desperate. She clawed at his back. Nails leaving red trails down his skin.

"I'm close," she gasped. "Caleb, I'm gonna come."

"Come on my cock," he ordered. "Let me feel it. Milk me dry."

He angled his hips just right. Ground against her G-spot on every thrust. Thumb pressed harder on her clit.

Riley shattered.

Her pussy clamped down in violent pulses. Clear fluid gushed out around his shaft, soaking his balls, his thighs, the sheets beneath them. She bit her own arm to muffle the scream. Body convulsing. Thighs shaking uncontrollably.

Caleb fucked her through it. Short, brutal thrusts that dragged the orgasm out until tears leaked from the corners of her eyes.

When the spasms slowed he pulled out completely. Flipped her onto her stomach. Yanked her hips up high. Ass presented. Pussy still twitching and leaking.

He spat on her tight back hole. Pressed the fat head of his cock against it.

"Relax," he murmured. "Breathe for me."

Riley pushed back instinctively. He pushed forward slow but relentless. Stretching her open inch by burning inch. She moaned long and trembling as he sank deeper. Deeper. Until his hips met her ass. Cock fully seated in her tight channel.

"Fuck," he hissed. "So goddamn tight back here."

He started moving. Slow deep thrusts at first. Letting her adjust. Then harder. Faster. One hand slid under her. Three fingers plunged back into her soaked pussy. Curling against her front wall while his thumb circled her clit.

Double filled. Cock pounding her ass. Fingers wrecking her cunt.

Riley's moans turned into broken sobs of pleasure. "I'm gonna come again. Fuck. Caleb."

"Come," he growled. "Come with my cock in your ass and my fingers in your pussy. Squeeze me."

She detonated harder than before. Ass clamping rhythmically around him. Pussy gushing around his fingers in violent waves. The dual orgasms ripped through her so intensely her vision blurred white for seconds.

Caleb followed right after. Growling her name low in his throat. He buried himself deep and flooded her ass with hot thick spurts. Pumping until it leaked out around his shaft.

He collapsed over her back. Both of them panting. Sweat slicking every inch of skin. His cock stayed buried inside her ass. Softening slowly but not pulling out.

He kissed the back of her neck. Soft. Possessive.

"Rest," he whispered. "Five minutes. Then I'm flipping you over and fucking you slow and deep until you can't take anymore."

Riley laughed shakily. Voice wrecked. "I can take whatever you give me."

He nipped her shoulder. "Good. Because we're not stopping until morning."

They lay there catching their breath. Bodies still joined. Hearts hammering in sync.

Then a soft knock came from the hallway.

"Riley? Caleb?" Harper's sleepy voice floated through the door. "You in there? I woke up and you're not in my room."

Riley's eyes snapped wide. Caleb's hand instantly covered her mouth. Gentle but firm. His cock twitched inside her at the sudden danger.

Harper knocked again. "Caleb? I heard noises. You okay?"

The doorknob rattled.

Caleb's gaze locked on Riley's. Dark. Hungry. Unmoving.

He stayed buried deep.

The knob turned slowly.

The door creaked open an inch.
