That was enough. She was close to coming, but that wasn't going to happen yet.

He rose up onto his knees, breathing fast, his heart pounding. He moved away from her. "Roll over," he growled.

There was enough play in the rope that she could roll to her front. She bent one leg, pushed a foot into the mattress and rolled, arms above her head. Her hair fell all over her face so he carefully smoothed back the long dark strands and adjusted the pillow for her.

He traced the whip down the center of her back. He tickled her buttocks, the backs of her thighs and knees. She squirmed. A pink flush tinted her gorgeous skin everywhere. Then he snapped the whip harder on one ass cheek. She jolted and gave a whimper. He flicked again. And again.

Out of the corner of his eye, he saw Aidan grip the armrest of the chair and push forward as if he was going to rush over there. Zack gave him a direct look. "Don't move."

Aidan's eyes narrowed. His breathing was shallow, his knuckles white. "Fuck," he muttered.

"Trust her," Zack said. "To know what she needs. She has the power to stop it with one word, remember?"

Aidan gave a short nod, his lips thinned.

"More." Her voice was muffled by the pillow, but Zack and Aidan both heard her.

Zack swept his hand over the smooth curve of her bottom. "So pretty."

He used the whip more and carefully took her up, letting her experience the high of the endorphins that had to be rushing through her veins. He watched her eyes get glassy as she floated off. Then he knelt on the bed, dropped the whip, and covered her ass with his hands. He rubbed her gently, up and down her back, bent and laid his lips on one cheek. "Such a good girl," he murmured. "So hot, Maddie." He slipped his fingers between her legs and found liquid heat. Her ass lifted invitingly. He stroked deeper through her silky folds.

"Please." She lifted to his touch. "Oh, please."

"You wanna be fucked?"

"Yes. God yes."

He looked at Aidan, eyebrows lifted. Aidan swallowed. "It's her call," he said hoarsely.

"Maddie?" Zack laid his palm between her shoulder blades. "You wanna be fucked by me?"

"Yes!"

Zack picked up the condom he'd hopefully set on the bedside table earlier. Maddie was hot and wet and desperate. He wanted to take her up even higher, give her the orgasm of her life with all the feel-good hormones coursing through her, her senses all heightened. He rolled it on as fast as he could and moved over her. Her pretty ass was all rosy, as were her face cheeks.

Once more he paused to draw back her hair, smoothing it off her hot face. Then he gripped her hips and lifted. He pushed into her, deliberately not being gentle. She cried out and gasped as he filled her. She was wet, so fantastically wet, but tight.

Jesus. It had been so long for him. He'd stayed in control through all their playing, but now, fucking a woman-fucking Maddie, for Chrissake-almost made him lose it. His head spun with incredulity and excitement. He was fucking Maddie. Maddie.

Maddie, who turned out to have a little masochistic bent. How had he never known this? Of course, he hadn't really explored his dominant, sadistic side until after he'd left Chicago. Before that, he'd tried to pretend that part of him didn't exist, worried about what that meant about him.

He found a quick, hard rhythm. The pull of her sweet pussy on his dick had electricity sizzling through his body, tightening every nerve ending. He laid a sharp tap on her ass, one side then the other, then reached up and gathered her hair into a tail in his fist. He tugged and her head came up and back. "Like that?"

"Yes. Please. More."

He twisted her hair in his hand, loving her breathless whimpers, the sound going straight to his balls. Her begging set him on fire.

Control. He had to hang on for her. This had to be good for her, probably the first time she'd had sex while riding the high of that sweet, dark pleasure. He slid a hand around over her belly, her mound, and found her clit. She spasmed around him as he touched her there, circling wet fingers over the taut bud.

"Yes," she gasped. "Oh god, Zack. I don't think I can stand it."

He leaned over and kissed her back. "Yes, you can." He stroked his tongue over her smooth skin. "You can do it." Then he closed his teeth on the muscle of her shoulder in a primal bite of ownership.

Her body jerked and she cried out. "Aidan," she whimpered.

Aidan was immediately at her side. "What, Maddie? You okay?"

"Yes. So good. Want you...just want you here. Hold my hands."

Aidan flashed Zack a look, then reached over to grip Maddie's restrained hands.

Zack licked his lips, pinched Maddie's clit and she wailed. Her pussy rippled around him as she shuddered through a hard orgasm.

Chapter Thirteen.

The violent pleasure consumed her. Heat radiated over her ass, and tingles cascaded from her scalp where Zack tugged her hair, down to the base of her spine. Her entire body shimmered with a dark, heady euphoria she'd never experienced. Zack's fingers at her clit coaxed her orgasm to the edge and then her world went black as it exploded inside her. Her body clenched hard around Zack's cock where he stroked over supersensitive nerve endings. She flew away and lost herself.

She was vaguely aware of Aidan's hands clutched in hers. She gripped him tighter as Zack continued to hammer into her, extending her pleasure almost unbearably, but she embraced it and reveled in it. So much sensation. Zack's hands gripped her hips and then he groaned and held himself balls-deep inside her. Sensitized so much, she felt his wrenching spasms inside her.

"Maddie," he gasped behind her, his voice raw. "Christ, Maddie."

She'd given that to him. She and Aidan. Her eyes stung.

Zack slid slowly out and back into her body, once...twice. His hands gentled on her, then caressed her tender buttocks. Then he dropped over her, hands planted in the mattress on either side of her. "Baby. You were amazing."

She moved her head in dissent. She'd done nothing. He was the one who'd given all that to her. Her chest squeezed with emotion and she began to tremble. As Zack eased out of her she felt a sense of loss. He knelt beside her to untie the ropes at her wrists, unwrapping her with practiced efficiency. "There," he murmured. "Okay, baby? Move your fingers. Any numbness?"

She tried to focus. Aidan's hands loosened on hers but still touched her. She flexed her fingers. "No."

"Good. Rub her hands and arms," Zack instructed Aidan. "Get into bed with her under the covers. She needs to be held and kept warm. Gotta get rid of this condom."

The bed shifted as he moved off and again as Aidan joined her, tenderly lowering her arms. He got them both under the covers, her back to his front, arms around her rubbing her hands and wrists. She trembled and tried not to cry.

Again all the emotion. It was crazy how Zack brought that out of her. And yet she also felt an incredible sense of peace and freedom.

"Okay, sweetheart?" Aidan whispered against her hair.

"Yeah. I'm good. Better than good. I don't even..."

"I know. Not sure what to say myself. I was worried at first..."

"I know."

"But I could see how much you loved it. That was so fucking hot." He stroked her forearms.

Zack returned and stood beside the bed, now wearing his boxers. "Okay?" he asked Maddie quietly.

She loved how they were both concerned about her. An overwhelming sense of gratitude rose up inside her. "I'm good." She stretched a hand out to Zack. He hesitated, then sat on the bed to take it. "Thank you, Zack."

He looked down at her hand in his. Silence expanded. "Thank you," he finally said in a low voice. "You have no idea what a gift you just gave me."

She swallowed. "I guess it's been a while since you..."

"Had sex?" One corner of his mouth lifted. "Yeah. That too. But it was more than just that. I needed that control. My life was so out of my control all those months. And I need that...dominance...to balance me. If I don't have that I don't feel whole. You made me feel whole for the first time in a long time."

"Oh." She let out a long breath and squeezed his hand. She thought she'd done nothing, so the idea that she'd given something to him too pleased her. "I don't...I guess I need to understand you better."

"Not much to understand," he muttered, still looking down.

"I think there is."

Zack glanced at Aidan. "You okay, man? Are we okay?"

Whoa. She knew why he asked that. Another man had just fucked her in front of Aidan. If she thought about that too much, she'd probably start freaking out and screaming. But it felt so...right.

"Yeah," Aidan said. "We're good."

"You liked watching," Zack stated.

"Yeah. I like watching Maddie gets what she needs. That's what I want. That's all I've ever wanted." He paused. "You like watching too."

"As long as I'm controlling the action." Like he had last weekend. There was a long pulsing moment as Zack looked at Aidan. "But I think you want more than that."

Aidan's body immediately tensed against her. Her mind raced back to when Zack had asked-no, ordered-Aidan to undress him. And he'd done it. Watching the two men together had been unbearably hot. The tension between them had crackled-Aidan's resistance yet compliance to Zack's authority along with the sexual electricity that arced as Aidan removed Zack's clothing, then Aidan's obvious study of Zack's erection.

Ideas floated around in her head, the things Aidan wanted her to do to him, the way he obeyed Zack...and she knew that Zack was right. Aidan did want more from this. Was he willing to admit it?

Much as Aidan had been pained to know he couldn't give her what she needed, she too struggled with the fact that there were things he wanted that she couldn't do. Well, she could do them. She just didn't get off on them.

But Zack...Zack did. So far this had been all about her. But maybe it didn't have to be. Maybe they could give something to Aidan too.

"Gonna say goodnight." Zack kissed her hand then released it and pushed up to his feet. "See you tomorrow."

As he left their bedroom, Maddie watched with a heavy feeling inside her. They'd started this thing, whatever it was, but still, she and Aidan were a couple and Zack was on the outside. And she found she didn't like that.

At that moment, it all overwhelmed her, everything pushing in on her and squeezing her until she couldn't breathe. Her mind shut down. She couldn't deal with it. So many emotions swamped her-fear that she and Aidan were doing something terribly wrong, compassion for Zack, guilt and shame mixed with an incredible joy and satisfaction and longing for more.

"Going to sleep," she mumbled to Aidan.

He reached for the lamp and with a click, darkness shrouded the room. He shifted her against him, settling in, and they slept.

________.

They all woke up late the next morning, Saturday. Maddie tried not feel weirded out by the fact that she'd had sex with Zack last night. With not only Aidan's consent, but his enjoyment.

It seemed they all had a definite kinky side that they'd never realized about each other before. Well, why would they? They'd all just been friends back in college. She and Aidan had known that Zack thought he was bisexual. That wasn't kinky. That was just him. And as for her and Aidan...their recent attempts to fly their freak flag hadn't been all that successful. They weren't sure of what they wanted and even less sure how to give it to each other.

But wow...these nights with Zack had been incredible. Heart-stoppingly, eye-poppingly incredible.

"I'm having lunch with Chelsea and Nisha," she told the guys. "Then going shopping."

"If you bring any more shoes home, an equivalent number of pairs have to go," Aidan said. "There's no fucking room left in our closet."

She gave him a look of mock horror. "I can't get rid of any shoes."

"Sweetheart. We should call you Carrie Bradshaw."

Zack snorted, reading the newspaper.

"You like my shoes. I know you have a thing for stilettos."

Zack lowered the paper and looked over at her with a smirk. "Oh yeah."

She groaned. "You too?"

"Do you have any red ones?"

"She does," Aidan affirmed. Shockingly, the two guys looked at each other with raised brows and nodded.

"Oh yeah," Zack said. "Red stilettos tonight. And nothing else."

Her entire body tightened with a little flip low in her belly. "Um. What?"

Zack's grin was evil as he folded the paper up. "Got things planned for tonight. But you go have lunch with your girls." He looked at Aidan. "What are you doing today?"

Aidan shrugged. "I could do some work."

Maddie's mind was buzzing with the thought of what Zack had planned for tonight. Sweet Jesus.

"I'm going to the Apple Store," Zack said. "I got my camera, but I need a computer. A new Mac. And a phone. Come with me."

"Okay. Sure. I like the Apple store."

"If you come home with another computer, you have to give one of your others away." Maddie smirked.

Zack burst out laughing and a reluctant smile tugged Aidan's lips. "Oh sweetheart. That is not the same as shoes."

"Sure it is! How many computers do you need? You have a desktop, a laptop, two iPads, plus some other tablet and an e-reader."

"One's a regular iPad, the other's an iPad mini."

Zack laughed again. "Dude. Maybe you better stay away from the Apple Store."
