"You know what I've always wondered?" Mia mused, her eyes glancing over the ancient Greek statue they had just discussed in their art history seminar.

"What's that?" Piers asked, his eyes lingering on the same marble form.

Mia turned to him with a mischievous smirk, her fingers idly playing with the hem of her blouse. "If you've ever been curious about... you know, the female body." She bit her lower lip, a hint of challenge in her voice.

Piers' eyes snapped to hers, surprise flickering in his gaze. He chuckled, the sound low and a little self-conscious. "Well, I've always appreciated beauty, Mia, but I've never really—"

"I know you're not into women, but I've seen the way you look at me sometimes," she said, cutting him off with a knowing smile. "And I can't say I haven't noticed you checking me out." She stepped closer, the fabric of her skirt brushing his leg. "It's okay, Piers. I'm curious too."

He swallowed hard, his heart racing. "What do you mean?"

Mia took a deep breath, her chest rising and falling in a way that drew his eyes. "I want you to explore me," she whispered, her voice dropping to a seductive purr. "I want to know what you think. If you're curious, I want you to satisfy that curiosity."

Piers felt a thrill run through him, a mix of excitement and nerves. He'd never done this before, but the way Mia looked at him, the way she was offering herself up like a delicate, untouched masterpiece, was too tempting to resist. She began to undo the buttons of her blouse, her eyes never leaving his.

"You're serious?" he managed to ask, his voice hoarse.

"Deadly," she said, the last button popping open to reveal the lacy edge of her bra. She shrugged the blouse off her shoulders, letting it fall to the floor. "I want you to touch me, Piers. Everywhere."

He stepped closer, his fingertips brushing the soft skin of her waist. "I don't know where to start," he admitted, his voice barely above a whisper.

Mia reached up and cupped his cheek, her eyes smoldering with desire. "Start with what you're most curious about," she said, her voice husky with anticipation.

Piers nodded, his gaze dropping to the swell of her breasts. He traced the lace of her bra with the backs of his fingers, his curiosity piqued. With trembling hands, he unclipped the front clasp, letting her breasts spill into his palms. He stared, fascinated by the way they felt, the way they moved under his touch.

Mia gasped, her body responding to his tentative exploration. She felt a heat building in her core, her nipples tightening into hard peaks. "You can touch them," she urged, her voice breathy. "Squeeze them, see how they feel."

He did as she said, rolling her nipples gently between his thumbs and forefingers. She moaned, her back arching slightly. He watched in awe as her body reacted to his touch, her skin flushing a soft pink.

"More," she murmured, her eyes closed in pleasure. "I want to feel you everywhere."

Without another word, Piers let his hands wander, exploring the curves of her body with a gentle touch. He felt her tremble under his fingertips, her breath catching in her throat as he discovered new territories. He'd seen her naked before—they'd shared a bottle of wine and a lazy evening in their underwear—but this was different. This was intimate, this was... hot.

Mia's eyes fluttered open to meet his, her pupils dilated with arousal. "Your turn," she said, her voice a whisper of challenge.

Piers' heart raced, his curiosity about to get the better of him. He nodded, his gaze dropping to the juncture of her thighs, where he could see the dampness of her arousal through the thin fabric of her panties.

He hooked his thumbs into the waistband and tugged them down, letting them pool around her ankles. Mia stepped out of them, standing before him in nothing but the collar she'd put on earlier—the one that made her feel like a naughty puppy. She watched him, her heart racing, as he took in the sight of her.

Piers' eyes were wide with wonder, his gaze lingering on the triangle of dark curls between her legs. He reached out tentatively, his fingertips tracing the line of her pussy, and she couldn't help but gasp. It was the lightest of touches, but it sent a bolt of pleasure through her body.

"You're so wet," he murmured, his voice filled with amazement. "Does this turn you on?"

Mia nodded, her cheeks flushing. "Yes," she breathed. "Your curiosity... it's so... hot."

He leaned in, his breath ghosting over her skin as he studied her closer. She felt the warmth of his mouth as he pressed a gentle kiss to her inner thigh, and she had to bite her lip to keep from crying out.

"What do you want?" she asked, her voice barely above a whisper.

Piers looked up at her, his eyes dark with desire. "Everything," he said simply.

And with that, he parted her folds, his tongue darting out to taste her. Mia's legs nearly buckled as he began to explore, his touch light and curious. He licked and kissed her, tracing patterns and shapes that had her panting and writhing.

"Tell me what feels good," he murmured against her skin. "Guide me."

Mia's hips rolled in response, her hands tangling in his hair. "Just... keep doing what you're doing," she gasped. "It feels amazing."

He did, his tongue delving deeper, his curiosity driving him to learn every inch of her. And as he did, she found herself getting closer and closer to the edge. Her orgasms usually came from penetration, but the way he was worshipping her with his mouth, the way he was discovering her, was pushing her to heights she hadn't experienced before.

"Oh god, Piers," she moaned, her legs beginning to shake. "I'm going to come."

And she did, her body convulsing as wave after wave of pleasure crashed over her. She felt his tongue swirl around her clit, lapping up her juices, and she knew he was getting off on it too—on the power he had over her body, on the sounds she was making, on the way she was losing control under his touch.

As she came down from her high, she reached for him, pulling him to his feet. "My turn," she whispered, her voice a little shaky.

Piers grinned, his cheeks flushed with excitement. He knew what was coming next, and the anticipation was driving him wild.

Mia took the collar off and placed it around his neck, her eyes gleaming with mischief. "Now," she said, "you're mine to explore."

He nodded, his eyes glazed with lust. "Whatever you want," he said, his voice thick with desire.

And with that, she began to explore him, her hands tracing the muscles of his chest, his abs, the V that dipped down below his waistband. She felt his cock strain against his pants, and she knew she had him right where she wanted him.

"Take them off," she ordered, her voice firm.

Piers obeyed, his hands fumbling with his belt and zipper. He stepped out of his pants and boxers, his erection springing free. She took him in her hand, feeling the heat of him, the velvety softness of his skin over the steel of his arousal.

"You're so big," she murmured, stroking him slowly. "And so hard for me."

"Mia," he groaned, his hips jerking.

"Tell me what you like," she said, her voice teasing. "Tell me how to make you feel good."

He closed his eyes, his breath coming in ragged gasps. "Just like that," he managed. "Keep going."

And she did, her hand moving faster, her grip tightening. She watched his face, the way his features contorted with pleasure, the way his body responded to her touch. It was intoxicating, having this power over him.

"I'm going to suck you," Mia whispered, her eyes never leaving his. "But first, you have to tell me you want it."

"Oh, I want it," Piers groaned, his hips bucking into her hand.

With a wicked smile, she dropped to her knees, her eyes on his face the whole time. She licked her lips, savoring the moment before she took him into her mouth. His cock was hot and thick, and she could taste the pre-cum beading at the tip. She licked it away, watching his eyes roll back in his head.

Piers' hands found her hair, his fingers threading through the strands as she took him deeper. She could feel his body tightening, his muscles coiling as she sucked and licked, her own arousal building once again. She loved the way he tasted, the way he felt in her mouth, and she knew he was loving every second of it.

"Fuck, Mia," he moaned, his hips thrusting gently.

Her eyes flicked up to meet his, and she could see the desperation in them. He was close, so close, and she wanted to watch him come apart. She sped up, her tongue swirling around the head of his cock, her teeth grazing the sensitive skin.

And then he did, his body tensing as he shot his load into her mouth. She swallowed greedily, loving the taste of him, the way he shuddered with pleasure. When he was spent, she licked him clean, a smile playing on her lips.

"Your turn," she said again, standing up and kissing him deeply, sharing the taste of him.

Piers' hands were shaking as he unbuttoned her skirt, letting it fall to the floor. He reached for the collar, his eyes never leaving hers. "Wear it," he said, his voice firm.

Mia felt a thrill run through her as she obeyed, fastening the collar around her neck. It was a symbol of her submission, a reminder of the power dynamics at play, and it turned her on even more.

"Good girl," he murmured, his voice low and filled with satisfaction. "Now, bend over the couch."

Mia did as she was told, her heart racing. She felt his hands on her ass, spreading her cheeks, and then the blunt pressure of his cock at her entrance. He pushed in, slow and steady, filling her completely.

"Oh, Piers," she gasped, her body stretching to accommodate him.

He began to thrust, his movements strong and sure. She could feel every inch of him, the way he filled her up, the way he claimed her. And she loved it, loved the feeling of being taken by her best friend, by a man she knew would never be fully hers in the traditional sense.

The collar grew tighter around her neck, a reminder of her submission. She pushed back against him, eager for more, her body begging for release.

"You like that?" he growled, his hips slamming into her.

"Yes," she moaned, her voice muffled by the cushions. "More, Piers. Harder."

He complied, his strokes growing more erratic, more forceful. She could feel another orgasm building, her muscles clenching around him, her body desperate for release.

And then it hit her, a wave of pleasure so intense it stole her breath. She screamed into the couch, her body shaking as he pounded into her, his own release close.

When he came, it was with a roar, his hips bucking hard, his cock pulsing inside her. They stayed there, locked together, for a moment that felt like an eternity, before collapsing in a heap of tangled limbs and heaving chests.

Mia lay there, the collar still around her neck, her heart racing. She'd never felt so alive, so free, so completely owned by someone else's desire. And as she looked up at Piers, she knew that this was just the beginning of their exploration, a new chapter in their friendship that she never wanted to end.
