Tempting My Brother’s Best Friend

13

Mia waited until the movie hit a loud chase scene. She stretched lazily, the cotton dress riding higher on her thighs, and stood up with a soft yawn.

“I’m going to use the bathroom,” she announced casually to no one in particular. “Be right back.”

Jake and Lila were too absorbed in the screen to do more than grunt. Sarah gave a small nod, still curled against Ethan’s side.

Ethan didn’t look at Mia as she walked past, but his entire body was screaming.

His c**k was painfully hard, throbbing against the fabric of his sweatpants, the head still slick from the precum she had spread with her thumb. Every heartbeat sent a fresh pulse of frustrated need through him. The denial hurt. It was a deep, aching throb that made his balls feel heavy and tight. He shifted uncomfortably, trying to hide the obvious bulge under the blanket, but the movement only made it worse.

He was so close when she stopped. So f*****g close.

The frustration burned hotter than the guilt. He wanted to finish. He needed to finish. And the fact that Mia had done it on purpose — that she had left him hanging while everyone else sat right there — made the ache even sharper.

Two minutes passed. The movie kept playing.

Ethan glanced at Sarah, who was laughing at a jump scare. Jake and Lila were whispering. No one was paying attention to him.

He stood up quietly. “I need some water,” he muttered, voice low enough that it blended with the movie.

Sarah barely glanced at him. “Bring me a soda?”

“Sure.”

He walked toward the kitchen, but the moment he was out of sight he turned down the hallway instead. His heart pounded. The bathroom door was closed. He waited just around the corner, hidden in the shadowed alcove near the guest room, breathing hard.

The toilet flushed.

The sink ran for a few seconds. The door opened. Mia stepped out, smoothing her dress. Ethan moved fast.

He caught her wrist, pulled her back into the bathroom, and shut the door behind them with a quiet click. The small space felt even smaller with both of them inside.

Mia’s eyes widened in shock. “Ethan — what are you—”

“Finish what you started,” he said, voice low and rough. His chest was heaving. The denial had left him desperate, c**k straining painfully against his sweatpants, a wet spot already darkening the front.

Mia blinked, feigning innocence. “I don’t know what you mean.” She tried to step around him toward the door. “I should get back to the movie before they notice.”

Ethan blocked her path, one hand on the doorframe. “You’re not going anywhere until you finish what you started in there.” His eyes were dark, pupils blown wide with frustration and need. “You got me right to the edge and then stopped. On purpose.”

A slow, teasing smile curved Mia’s lips. She tilted her head, looking up at him through her lashes. “I thought you weren’t interested,” she whispered, voice sweet and mocking. “You’ve been avoiding me all day. You said we can’t.”

She stepped closer, her body brushing his. Her hand trailed lightly down his chest, over his stomach, and stopped just above the waistband of his sweatpants.

“Changed your mind?” she asked softly.

Ethan’s breathing was ragged. “Mia…”

She sank to her knees right there on the bathroom tile, eyes never leaving his. The power shift was electric. He had pulled her in, but now she was the one in control — on her knees, looking up at him with that knowing little smile while he stood there aching and desperate.

She hooked her fingers in his waistband and tugged his sweatpants and boxers down just enough to free his c**k. It sprang out, thick, heavy, and flushed dark at the tip, already leaking steadily.

Mia wrapped her hand around the base and gave one slow stroke. Ethan hissed, hips jerking forward.

“Shh,” she whispered, glancing at the door. “They’re right down the hall. You have to be quiet.”

Then she leaned in and took him into her mouth.

The heat was overwhelming. Her lips stretched around him, tongue swirling over the sensitive head, tasting the salty precum that had been leaking for the last ten minutes. She sucked him deep, cheeks hollowing, taking him halfway before pulling back with a wet pop. Her hand stroked what her mouth couldn’t reach, twisting gently at the head on every upstroke.

Ethan’s head fell back against the door with a soft thud. One hand tangled in her hair, not pushing, just holding on as if she might disappear.

“f**k… Mia…” he breathed, voice strained.

She hummed around him, the vibration shooting straight to his balls. She bobbed faster, taking him deeper each time, the head bumping the back of her throat. Saliva dripped down her chin, making everything slick and messy. The sounds were obscene — wet sucking, her soft little moans, his ragged breathing.

The power dynamic was intoxicating. He was the one who had dragged her in here, but she was the one controlling every second — setting the pace, deciding how deep, how fast, when to swirl her tongue or suck harder. He was completely at her mercy, hips twitching, trying not to thrust too hard while she worked him closer and closer to the edge again.

Mia pulled off for a second, stroking him fast with her hand while she looked up at him. “You’re so hard,” she whispered. “Does it hurt?”

“Yes,” he groaned.

She smiled and took him back into her mouth, sucking harder, faster, one hand cupping his balls and rolling them gently. Ethan’s thighs trembled. He was right there again — right on the edge, so close he could feel the orgasm building at the base of his spine.

His hand tightened in her hair.

“Mia — I’m gonna —”

She pulled off completely again, lips shiny and swollen, hand still loosely stroking him.

Ethan let out a frustrated, broken sound.

Mia stood up slowly, wiping her mouth with the back of her hand. She leaned in and kissed his jaw, voice a soft whisper against his ear.

“You’ll come when I decide you can come,” she said sweetly.

She smoothed her dress, gave him one last teasing smile, and slipped out of the bathroom, leaving him standing there — c**k hard, aching, and completely denied once more.

Ethan leaned against the sink, breathing hard, trying to calm down before he had to go back to the movie.

He was in so much deeper than he ever planned.

And Mia knew it.
