Chapter 5: Jealous Flames

My Best Friend’s Stepbrother

Riley took a step forward. "I didn't plan this. It just... happened. I couldn't stop it."

Harper stood up. Fast. "You couldn't stop it? Or you didn't want to stop it?"

Caleb leaned against the wall. Arms crossed. Silent. Letting it burn.

Harper's voice cracked. "I trusted you. More than anyone. I told you my stupid crush. I told you I was going to try. And you... you took him instead. You took him while pretending to be my friend."

Riley's eyes filled with tears. "I know. I hate myself for it. But I couldn't help it. The way he looks at me. The way he touches me. It's like nothing else exists."

Harper laughed. Sharp. Painful. "Nothing else exists? Like me? Like our friendship? Like the fact that he's my stepbrother and I grew up in this house with him?"

Riley flinched. "Harper..."

"No." Harper stepped closer. Close enough that Riley could see the fresh tears clinging to her lashes. "You don't get to apologize and make it okay. You don't get to stand there naked and dripping his cum and act sorry."

Caleb finally spoke. "She didn't force me. I wanted her. Still do."

Harper whipped around to him. "Shut up. This isn't about you right now. This is about her betraying me."

Caleb pushed off the wall. "It's about all of us. You said you love me. You watched us fuck and touched yourself. Don't pretend you're innocent."

Harper's face flushed crimson. "I was in shock. I didn't know what to do."

Riley reached out. "Harper, please. We can talk. We can fix this."

Harper slapped her hand away. "Fix this? How? By sharing him? By pretending I didn't just watch my best friend get railed by the guy I've wanted forever?"

The words hung heavy.

Harper's breathing turned ragged. She looked at Riley again. Really looked. At the bite marks on her neck. The bruises on her hips from Caleb's grip. The way her thighs still trembled.

Jealousy hit her like a punch.

"You look so fucking happy," Harper whispered. "Like he gave you everything I've always wanted. And you took it. Without even thinking about me."

Riley shook her head. "I thought about you the whole time. The guilt was killing me."

"Then why didn't you stop?" Harper's voice rose again. "Why didn't you push him away? Why did you moan his name like that?"

"Because it felt good," Riley admitted. Quiet. Honest. "Because he makes me feel wanted. Needed. Like I'm the only thing that matters."

Harper's lip trembled. "He was supposed to make me feel that way."

Caleb stepped between them. "Enough."

He grabbed Riley's wrist again. Pulled her to his side. Possessive. "This isn't a competition. But if it is, Riley won. She's the one I fucked. She's the one I came inside. Twice today."

Harper stared at him. "You're an asshole."

"Maybe." Caleb shrugged. "But I'm the asshole you both want."

He turned to Riley. Kissed her hard. Right there. Tongue deep. Hand sliding down to grip her ass. Squeezing. Showing Harper exactly what she was missing.

Riley moaned into his mouth.

Caleb stopped deliberately. Then he walked around the couch. Sat on the table directly in front of Harper. Close enough that his knee almost brushed hers.

He looked at Riley first.

"Get up here," he said. Voice low. Commanding.

Riley pushed herself upright. Turned. Naked. Flushed. She walked the few steps to stand between them. Between her best friend and the man who had just fucked her senseless in front of her.

Caleb reached out. Grabbed her wrist. Pulled her onto his lap. Straddled him. Facing Harper. Her wet pussy pressed against the rough denim of his jeans. The friction made her hiss softly.

He wrapped one arm around her waist. Held her in place. His free hand slid up her stomach. Cupped her breast. Squeezed. Thumb circled her nipple slow and teasing.

Riley bit her lip. Tried to stay quiet.

Caleb leaned in. Lips brushing her ear. Loud enough for Harper to hear every word.

"You're still shaking," he murmured. "Still dripping on my jeans. You want more, don't you?"

Riley nodded once. Small. Desperate.

"Say it," he ordered.

"I want more," she whispered.

"Louder."

Riley glanced at Harper. Harper's eyes were locked on where Riley's hips rocked subtly against Caleb's bulge.

"I want more," Riley said again. Voice cracking.

Caleb's hand slid down. Between her thighs. Two fingers parted her folds. Slid through the mess of cum and slick. Found her clit. Rubbed once. Slow. Torturously light.

Riley whimpered. Hips jerked forward.

"Not yet," he said. "You don't get it yet."

He kept touching her. Light circles. Barely enough pressure. Enough to make her ache. Enough to make her thighs quiver. Not enough to let her come.

Riley's breathing turned ragged. "Caleb, please."

"Please what?"

"Please fuck me again."

He chuckled low. "Not good enough."

His fingers dipped inside her. Just the tips. Pumped shallow. Then pulled out. Back to her clit. Teasing. Denying.

Riley squirmed on his lap. Grinding against his hand. Trying to chase more friction.

Harper watched. Cheeks flushed. Breathing shallow. One hand had crept back between her own thighs. Pressing lightly over her shorts. Not moving yet. Just watching.

Caleb noticed.

He leaned forward slightly. Kept Riley pinned against him. Kept teasing her clit with feather-light strokes.

"Look at your best friend," he said to Riley. "She's watching you beg. Watching you leak all over me. And she's touching herself because of it."

Riley moaned. Soft. Broken.

Caleb's voice dropped. "You want my cock again?"

"Yes," Riley gasped. "Please. I need it."

"Then earn it."

He thrust two fingers deep inside her suddenly. Curled them hard against her G-spot. Pumped fast three times. Then stopped. Pulled out completely.

Riley cried out in frustration. "Caleb!"

He gripped her chin. Turned her face toward Harper.

"You want me to fuck you right now? Hard. Deep. Fill you again?"

Riley nodded frantically. "Yes. God yes."

"Then pull her in."

Riley blinked. "What?"

Caleb's fingers returned to her clit. Rubbed slow. Torturous. "Harper's right there. Watching. Wet. Jealous. Hurt. But turned on. If you want my cock, convince her to join. Kiss her. Touch her. Make her part of this. Or you get nothing."

Riley's eyes widened. She looked at Harper.

Harper stared back. Breath hitching. Hand still pressed between her legs.

Riley hesitated.

Caleb kept Riley locked on his lap. Her thighs spread wide over his. Her pussy pressed hot and slick against the rough denim of his jeans. His fingers traced lazy circles around her clit. Never quite giving enough pressure. Never letting her tip over the edge. Just enough to make her hips roll in slow, frustrated circles.

Riley's breath hitched every few seconds. Small whimpers escaped her lips. She gripped his forearms hard. Nails digging in.

"Please," she begged again. "Caleb. I can't take it. Fuck me. Please just fuck me."

He pressed his mouth to her ear. "You know what I want first."

His fingers dipped lower. Slid through her soaked folds. Pushed two inside her. Pumped once. Slow. Deep. Then pulled out. Back to feather-light teasing on her swollen clit.

Riley moaned loud. Body jerking. "Harper..."

Caleb glanced at Harper. She sat rigid on the couch. Arms crossed. Jaw tight. Eyes fixed on where his hand worked between Riley's thighs. Her chest rose and fell too fast. Nipples hard under her thin pajama top.

"Touch her," Caleb said to Riley. "Down there. Make her feel what you're feeling. Or I stop right now and you get nothing tonight."

Riley swallowed hard. Looked at Harper.

Harper shook her head once. Sharp. "Don't."

But she did not move away.

Riley reached out slowly. Hand trembling. Fingers brushed the inside of Harper's thigh. Just above the hem of her shorts.

Harper tensed. Thighs clamped together for a second. Then parted. Barely an inch.

Riley's hand slid higher. Under the loose fabric. Found the damp cotton of Harper's panties. Pressed gently against the seam.

Harper sucked in a sharp breath. "Riley..."

Riley rubbed slow. Light circles over the fabric. Feeling the heat. The wetness soaking through.

Harper's hips twitched once. Involuntarily.

Riley pressed harder. Fingers slipping under the edge of the panties. Touching bare skin. Slick folds. Swollen clit.

Harper gasped. Eyes fluttering shut for a second. Then snapping open again. Locked on Riley's face.

"You feel that?" Riley whispered. "How wet you are? Same as me."

Harper bit her lip. Hard. "This doesn't fix anything."

"I know," Riley said. Fingers circling Harper's clit now. Slow. Matching the rhythm Caleb used on her own. "But it feels good. Doesn't it?"

Harper made a small, choked sound. Hips rocking forward into Riley's hand. Just a little.

Caleb watched. His cock throbbed under Riley's ass. He rewarded her. Thrust three fingers deep inside her pussy. Pumped hard. Fast. Curled against her G-spot.

Riley cried out. Body bowing. But she did not stop touching Harper. Kept rubbing. Kept circling. Slipped one finger inside Harper's tight heat.

Harper moaned. Low. Broken. "Fuck."

Riley pumped slowly. In and out. Thumb on Harper's clit now. Matching the desperate rhythm.

Harper's hand shot out. Grabbed Riley's wrist. Not to stop her. To hold her there. To push her deeper.

Caleb kept fingering Riley. Relentless. "Look at her," he said to Riley. "Look how she clenches around your finger. She's dripping for you. For us."

Riley looked. Harper's thighs trembled. Her free hand gripped the couch cushion. Knuckles white.

Harper's eyes met Riley's. Dark. Hungry. Angry. Wanting.

"Don't stop," Harper whispered. Voice wrecked.

Riley added a second finger. Pumped deeper. Faster.

Harper's head fell back. Moan turning into a sob of pleasure. "Riley... oh god."

Caleb pulled his fingers free from Riley suddenly. Left her empty. Aching.

Riley whimpered in protest.

He stood up. Lifted her off his lap. Set her on her knees between the two of them. On the floor.

"Keep going," he told Riley. "Make her come. Then maybe I'll give you what you want."

Riley looked up at him. Then at Harper.

Harper spread her legs wider. Shorts pushed aside. Panties tugged down. Pussy bare. Swollen. Glistening.

Riley leaned in. Fingers sliding back inside. Pumping. Curling. Thumb on clit.

Harper's hips bucked. "Harder."

Riley obeyed. Fucked her with her fingers. Fast. Deep. Wet sounds filling the room.

Harper shattered.

Her pussy clamped down hard. Gushed around Riley's fingers. Clear fluid coated Riley's hand. Dripped onto the floor. Harper's cry came out raw. Body convulsing. Thighs shaking.

Riley kept going until Harper pushed her hand away. Overstimulated. Panting.

Harper looked down at Riley. Then at Caleb.

Her voice came out hoarse. "Your turn."

Caleb unzipped. Cock springing free. Thick. Hard. Leaking.

He looked at Riley. "Beg again."

Riley looked up at him. Then at Harper. Both watching her.

"Please," she said. Voice trembling with need. "Fuck me. Both of you. I need it so bad. Fill me. Use me. Please."

Caleb stepped forward.

Harper reached out. Pulled Riley up onto the couch beside her.
