Tempting My Brother’s Best Friend

19

Ethan woke with Mia’s taste still on his tongue.

He lay perfectly still, staring at the ceiling while Sarah slept curled against his side, her arm draped across his chest. The memory of yesterday flooded him in vivid flashes — Mia bent over his bed, the wet heat of her p***y clenching around his c**k, the way she had moaned his name as he came deep inside her.

He could still feel the slick slide, the way her walls had fluttered and milked him through every pulse. His c**k twitched traitorously beneath the sheet, already half-hard again.

Guilt twisted like a knife in his gut. Sarah was right here, warm and trusting, and all he could think about was how perfectly Mia had taken him.

He slipped out of bed carefully, not wanting to wake her. Downstairs, the kitchen smelled like coffee and toast. Jake was at the stove flipping eggs. Lila sat at the island scrolling her phone. Mia was already there, wearing a thin tank top and tiny cotton shorts that clung to her hips.

Ethan poured coffee without looking at her. “Morning.”

“Morning,” Mia replied, voice sweet and normal. Under the table, her bare foot slowly slid up his calf.

Ethan tensed, nearly spilling the mug. He sat down quickly, but her foot followed, pressing higher, brushing the inside of his thigh with deliberate teasing pressure.

Sarah walked in a moment later, still in pajamas, and kissed his cheek. “Hey, babe. You were tossing and turning last night. Couldn’t sleep?”

Ethan forced a smile. “Just restless. Long day yesterday.”

Mia’s foot pressed more firmly against the growing bulge in his shorts. He shifted, trying to hide it, but the subtle movement only made her smile into her coffee.

Breakfast passed in a blur of normal conversation. Jake and Lila chatted about their plans. Sarah kept glancing at Ethan with quiet concern, but she didn’t push in front of everyone. Mia’s foot never stopped its slow, maddening strokes under the table, keeping him half-hard and aching the entire meal.

Later that afternoon, the house finally emptied. Jake and Lila left to run errands together. Sarah headed out for a quick errand, kissing Ethan’s cheek on her way out. “Be back in an hour or two, babe.”

The moment the front door closed, Mia appeared in the hallway.

Ethan was in the guest bathroom splashing water on his face when the door opened. Mia stepped inside and locked it behind her.

“Mia—” he started, but the words died when she closed the distance and kissed him.

The kiss was deep and hungry. Ethan groaned into her mouth, hands sliding under her tank top to cup her bare breasts, thumbs brushing her n*****s until they tightened. Mia whimpered, pressing closer, her tongue sliding against his with raw need.

Ethan pulled back just enough to look at her. “Are you on your safe days?” he asked, voice hoarse. “We should use a condom—”

Mia shook her head, eyes dark with desire. “I’m safe. We don’t need one. I want to feel you — all of you.”

That was all it took.

Ethan spun her around and bent her over the sink, yanking her shorts and panties down in one rough motion. He freed his c**k, already rock-hard and leaking, and rubbed the thick head along her soaked folds, coating himself in her slick.

“f**k, you’re dripping for me,” he groaned. He pushed inside her slowly, savoring every tight, wet inch until he was buried to the hilt.

Mia gasped, gripping the edge of the sink. “Ethan… you feel so good.”

He started moving — deep, powerful thrusts that made her breasts bounce in the mirror. One hand gripped her hip, the other slid around to rub her c**t in firm circles. The bathroom filled with the wet slap of skin on skin, her soft moans, and his low, ragged breathing.

“Look at yourself,” he whispered against her ear, voice rough with emotion. “Look how pretty you are taking my cock.”

Mia lifted her eyes to the mirror. Their gazes locked. The power dynamic was electric — he was the one f*****g her, controlling the pace, but she was the one who had broken him, the one who had made him risk everything.

“You’re mine now,” he growled, thrusting harder, the head of his c**k hitting that perfect spot inside her with every stroke. “This p***y is mine. Say it.”

“Yours,” she moaned, pushing back to meet him. “Only yours.”

He kissed her shoulder, then her neck, sucking a mark into her skin as he f****d her deeper, faster. The mirror showed everything — her flushed face, her bouncing breasts, the way her body jolted with every powerful thrust.

“I’m close,” she whimpered, walls starting to flutter around him.

“Come for me,” Ethan commanded, rubbing her c**t faster. “Come on my c**k like a good girl.”

Mia shattered with a choked cry, p***y clenching hard around him as her orgasm crashed through her. The rhythmic pulsing pushed Ethan over the edge. He buried himself deep and came with a guttural groan, flooding her with thick, hot spurts, hips stuttering as he emptied himself completely inside her.

They stayed locked together, panting, his forehead pressed to her shoulder.

“f**k,” he whispered, voice wrecked. “I can’t stop wanting you.”

Before Mia could answer, they heard the front door open.

“Babe?” Sarah’s voice called cheerfully from the hallway. “I’m back early!”

Ethan’s eyes widened in panic. He was still buried deep inside Mia, c*m slowly leaking out around his c**k.

He quickly pulled out, both of them moving in frantic silence. Mia yanked her shorts up while Ethan fixed his own clothes. They barely had time to smooth their hair and flush the toilet before Sarah’s footsteps approached the bathroom door.

Ethan opened the door, trying to look casual, his heart hammering. “Hey. You’re back fast.”

Sarah smiled, holding up her forgotten wallet. “Forgot this. I thought I heard a weird noise from the bathroom. Everything okay?”

Ethan forced a calm expression and stepped out, gently closing the door behind him so Mia had time to slip out unnoticed. He put an arm around Sarah’s shoulders and led her away from the bathroom toward the living room.

“Yeah, everything’s fine,” he lied smoothly. “The sink was acting up again. I was just checking the pipes. Nothing serious.”

Sarah nodded, though her eyes lingered on the closed bathroom door for a second. “Okay… you sure you’re alright? You’ve seemed a little off lately.”

“I’m good,” Ethan said, pulling her closer and kissing the top of her head. “Just tired. Let’s go sit down.”

As they walked away, Ethan glanced back once. The bathroom door cracked open slightly, and Mia slipped out quietly, heading toward the stairs without making a sound.

Ethan’s stomach twisted with fresh guilt.

He had just f****d Mia again — raw, deep, and unprotected — while his girlfriend was only minutes away.

And the worst part was how much he already wanted to do it again.
