The request

Josh nursed for a long while, switching back and forth between her breasts as Ariana directed. The warm, thick milk filled him completely, settling in his stomach like a heavy, pleasant stone. He drank until the flow slowed to a trickle, until her breasts softened slightly in his hands, until his own hunger was nothing but a distant memory.

Finally, he pulled away, his lips swollen and wet, his belly full and warm.

And then it happened.

A small, involuntary buurp escaped his lips.

His eyes went wide. His face flushed crimson.

"Oh my God," he whispered, mortified. "I'm so s-sorry."

Ariana burst out laughing, a bright, genuine sound that filled the small room. "Did you just burp?"

"I c-couldn't help it! It was the... the..." He gestured helplessly at her chest. "The milk."

"Milk burps," she said, nodding sagely. "A classic side effect of the A3 experience. Don't worry. It's actually kind of adorable." She reached out and ruffled his hair. "You look like a very satisfied baby."

"I'm not a b-baby," he mumbled, but there was no heat in it.

"No," she agreed, her smile shifting into something slower, more deliberate. "No, you're not."

The air in the room changed.

She sat up straighter, her posture shifting from relaxed to something more focused. Her eyes locked onto his.

"Well," she said, her voice lower now. "You've had your dinner. You're full. You're happy. And now..." She paused, letting the silence stretch. "Now it's time for my request."

Josh tensed immediately. His hands, which had been resting on her hips, went still. "I... I knew it. What is it?"

Ariana stood up from the bed in one fluid motion. She stood before him, bare-breasted, her tight blue shorts riding low on her hips. The soft light from the bedside lamp carved shadows across her stomach, her thighs.

"Don't look so worried, little brother," she said, placing her hands on her own hips. "I told you. You'll enjoy it."

"Enjoy what?"

She smiled, a slow, secret smile. "It's time to raise the stakes."

His brow furrowed. "Raise the... what does that mean?"

"It means," she said, stepping closer until her knees touched his, "that you're going to learn something completely new today. Something you've never done before. Something that every man should know how to do."

Josh stared up at her, his heart beginning to hammer again. "I... I don't..."

"That's the point, silly." She reached down and tapped his nose with one finger. "You don't know. That's why I'm going to teach you." She gestured to herself with a flourish. "Think of me as your instructor. Your personal, private, very generous instructor."

"Instructor for what?"

She didn't answer. Instead, she turned around slowly, presenting her back to him. Then she looked over her shoulder, her blue eyes glittering.

"Now," she said, her voice dropping to a low, commanding purr. "I want you to stand up."

He obeyed, his legs shaky.

"Good." She reached behind herself and took his hands, placing them on her hips, right on the waistband of her tight blue shorts. "And now... I want you to take these off."

Josh's breath caught. "Take... take them off?"

"Mhm." She pressed his fingers into the fabric, into the warmth of her skin beneath. "Pull them down. Nice and slow."

He hesitated, his hands trembling against her hips. "But... you're not... I mean, do you have...?"

She turned her head further, a smirk playing on her lips. "Underwear? No, Josh. I don't." She wiggled her hips slightly, the shorts shifting against his fingers. "I never do. Not with these tight shorts. Too many lines."

He felt lightheaded. His mouth opened, but no words came out.

"Come on," she encouraged, her voice soft but firm. "You were so brave before. So eager. This is just the next step." She reached back and patted his cheek without looking. "Don't be shy now. Not after everything we've already done."

He swallowed hard. His fingers curled around the waistband.

And then, slowly, trembling, he began to pull them down.
