Tempting My Brother’s Best Friend

18

The kitchen island was crowded that evening. Lila sat on one of the stools, laughing at something Jake said while she chopped vegetables. Sarah leaned against Ethan’s side, her arm looped casually around his waist as she scrolled through her phone. Jake stood at the stove stirring pasta sauce, and Mia leaned on the opposite counter, sipping water and watching the scene with a calm smile that didn’t reach her eyes.

Everything looked perfectly normal — five friends hanging out in the house while the parents were away. But for Ethan, the normalcy felt like a lie.

Sarah pressed a quick kiss to his shoulder. “You’re quiet. Everything okay?”

“Yeah,” Ethan answered, one-word reply. He kept his eyes on the cutting board, chopping onions with more focus than necessary.

Ethan kept his gaze on his plate. He could still feel Mia on his skin, still taste her, still hear the way she had moaned his name when he came inside her earlier. Every time Sarah touched him, guilt twisted harder in his gut.

Jake’s phone rang suddenly. He glanced at the screen and grinned. “It’s Mom and Dad.”

He answered on speaker. “Hey! How’s Europe?”

Their mom’s voice filled the kitchen, bright and excited. “Amazing! We’re in Paris right now. How are you two holding up? Is everything okay at home?”

Jake laughed. “Everything’s great. We’re all just chilling, eating pizza. Mia’s been studying hard.”

Mia forced a smile. “Hi Mom. Hi Dad. Everything’s fine here.”

Their dad chimed in. “Good to hear. Ethan still keeping an eye on things?”

Ethan cleared his throat. “Yes, sir. Everything’s under control.”

Sarah squeezed his arm affectionately. “He’s been a great help.”

The call continued for a few more minutes — updates about the trip, reminders to keep the house clean, questions about whether they needed anything. Jake reassured them everything was perfect. When they finally hung up, the kitchen felt heavier somehow.

The call ended with the usual “We love you” and “Be good.” Jake hung up and went back to the stove. “They sound happy. Two more days and they’ll be back.”

Sarah smiled and cuddled closer to Ethan, resting her head on his shoulder. “That’s nice. We should do something fun before they get home.”

Mia watched Sarah press against Ethan’s side, her hand resting casually on his chest. The casual affection sent a sharp stab of jealousy through her. She forced her expression to stay neutral, but her fingers tightened around her glass.

Later that night, after dinner and a movie, everyone started heading to bed. Jake and Lila disappeared into Jake’s room. Sarah followed Ethan into his guest room, closing the door behind them.

Sarah changed into one of Ethan’s old t-shirts and climbed into bed beside him. She snuggled close, her hand sliding under his shirt to trace his abs.

“I missed you today,” she whispered, pressing soft kisses along his jaw. “We haven’t had much time alone since I had been going to work.”

Ethan tensed. “Yeah… been busy with the pool and stuff.”

Sarah’s hand moved lower, brushing over the front of his shorts. “We could fix that now…”

He caught her wrist gently. “Not tonight. I’m really tired. Long day.”

Sarah frowned but didn’t push. “Okay… everything fine though?”

“Yeah,” he said again, the same one-word answer he’d been giving all day. “Just tired.”

She eventually fell asleep curled against his side.

Ethan lay awake, staring at the ceiling. His phone buzzed on the nightstand. He glanced at Sarah — she was breathing evenly, deeply asleep — then picked it up.

Mia: Can’t stop thinking about earlier. You still inside me. The way you sounded when you came.

Ethan’s c**k twitched instantly. He typed back with one hand, keeping his movements small.

Ethan: Mia, stop. Sarah is right here.

Mia: I’m touching myself thinking about your c**k stretching me. How full I felt. How you filled me up.

Ethan’s breathing grew heavier. He shifted carefully, trying not to wake Sarah. His free hand slipped under the blanket, palming his growing erection.

Ethan: You’re going to get us caught.

Mia: Tell me what you’d do if you were here right now.

He hesitated, guilt twisting in his chest, but the ache won.

Ethan: I’d pin you down and f**k you slow. Make you feel every inch. Make you beg for it.

Mia: I’m so wet. I wish it was your fingers instead of mine.

The texts continued, growing filthier. Mia described how she was circling her c**t, how she was imagining his mouth on her again. Ethan stroked himself under the blanket, slow and careful, biting his lip to stay silent. The thrill of Sarah sleeping right beside him made every word hotter, every stroke more dangerous.

Mia: I’m close… tell me to come for you.

Ethan: Come for me, baby. Quietly.

He imagined her biting her lip to stay silent, her body arching as she came. The thought pushed him over the edge. He came hard into his hand, biting back a groan, hips jerking slightly.

The phone buzzed one last time.

Mia: Goodnight, Ethan. Sweet dreams.

He deleted the entire conversation, wiped his hand on a tissue, heart pounding, and set the phone down.

Sarah stirred slightly beside him but didn’t wake. Ethan stared at the ceiling again, chest tight. He had just sexted Mia while his girlfriend slept next to him.
