"So why are you going to put yourself through this?" she asked, "you could have already had sex several times today. I don't understand it. You've got three women that love you and want to fuck you regularly, and they all know about each other and are more than willing to share you. Men have killed for less."

"Listen to her, she's a fucking genius."

He shrugged. "I've just got to prove to myself that I can resist some of these impulses."

"Some?" she asked, smiling and drawing close to him.

He chuckled again as she drew even closer, straddling the machine and him to come to rest on his lap. She wrapped her arms around him and kissed him, but quickly remembered they were in public. Fearing suddenly someone they knew might see them, she quickly dismounted.

"It's even easier now to forget that you're my brother," she said quietly.

She turned and headed for the bathroom, stopping at the doorway and winking at him. Mike grinned. She reappeared a few seconds later, biting her lip nervously and quickly waving him forward, disappearing behind the door.

Mike smiled widely, immediately knowing what she had in mind. He waited fifteen to twenty seconds, glanced around the room at the two or three other guys still lifting weights. They all seemed to be way more interested in flexing and admiring themselves, and seemed not to be giving any notice of Danni, nor himself.

"I'm about to win the bet, aren't I."

'Nope,' Mike thought back to the voice.

He quickly went towards the men's shower room, but turned at the last second, letting the door to the female bathroom close quickly behind him. Danni was in one of the showers already, soaping her naked body. She smiled as his head appeared around the corner. She was in a shower stall, the curtain open, water cascading down across her short brown ponytail and down her back, over her shoulders, causing her nipples to harden and point outwards from her perky breasts.

Mike realized this was the first time he'd seen her in any brighter light than the glow of a full moon, and took the chance to admire her flawless body, but from a safe distance. Her breasts were larger than Emma's, but smaller than Sarah's. She had pink nipples, and dark tan lines, something that caused Mike's dick to jerk, and it hardened even more than it had already been.

She closed her eyes, knowing that he was watching her, running her hand along her body, washing bubbles across her tanned skin and across her breasts. She ran her hand across her nipples and down her stomach, between her legs and farther, running a finger across her pussy, lingering for a few seconds, and then traveling upwards towards her stomach again, and then the other breast. She ran the other hand down towards her snatch, still pinching her nipples with the first as she slid a finger into her pussy.

Mike felt like he was going to faint. His gorgeous sister was masturbating for him in public. He felt like running over to join her and lend a helping hand.

"That would've been my suggestion, but noooooo, so why bother."

Just then, the door to the locker room swung wide open and a few girls walked in. They spotted just Mike's back as he bolted from the room, immediately heading out the side door and into his truck.

Danni burst out laughing as she heard him leave. Picking up her things, she exited the shower room. She dressed quickly then caught up to Mike in his truck, covering her mouth as she did so. Once inside, she burst out laughing, seeing Mike's face turning nine shades of red and his breathing heavy from his adrenaline dump. He glared at her for a second, before her giggles caused him to smile too.

"You're almost as bad as Sarah and Emma," he said.

She cackled at him for a few seconds, leaning over and laying her head on his shoulder as they started for home.

"Well, we are sisters," she said after her laughter had subsided, giggling again as she finished.

They pulled up to the house a few minutes later and went inside and were greeted by Sarah. She was wearing a short skirt and matching blouse, carrying a load of folded clothes toward the stairs. She dropped a towel on the floor and set the rest of the load on the table as Danni and Mike came in through the door. Smiling, she bent over to get the towel, and both of them caught an eyeful of her naked ass, peeking out from under the skirt as she bent over.

Danni just closed her eyes, laughing as quietly as she could. Mike shut his eyes as well, trying not to grin and softly shaking his head. They both headed for the living room a few seconds later as Sarah stood, nonchalantly folded the towel, picked the stack back up and headed upstairs.

"Man I love your sisters."

His sisters must have finally decided to give him a break, and throughout the rest of the evening, they sat and watched TV, behaving and not tormenting him. As it grew late, Mike even leaned over and kissed each of his sisters on the cheeks before heading upstairs. Danni took his hand as he kissed her cheek, and prompted him to pull her from the couch. As he did she led him away by the hand.

"Night you guys," Sarah called after them, but for the first time, without a smile on her face.

They slowly walked upstairs, hand in hand, and as they reached the top step, she stopped him. Danni was several inches shorter than him, and as she stood in front of him two steps above, he found himself looking at her eye to eye. She smiled at him and kissed him on the cheek.

He leaned forward to kiss her back, but she put a hand on his chest and gently pushed him backwards, straightening him back up and drawing a confused look from him.

"Mike, I understand if you don't want to make love. I know it's important to you that you prove... whatever the hell it is you are trying to prove to yourself. I love you, and I guess I can do without sex for one night."

Mike didn't know if he could lover her any more than he did at that very moment, but he was sure going to try. Without saying a word, he effortlessly lifted her up, causing her to squeal in astonishment. He carried her into his room, kicking the door closed behind them, and laid her gently on the bed as he began to kiss her face.

"Wow," she said, feeling his lips pressing into her cheeks, across her forehead and to her ear lobes. "I guess I won't have to do without after all."

He smiled and continued kissing, moving from her ears down to her upper neck, planting kisses downwards and to the muscle connected to her neck and shoulder, drawing a giggle and a sigh of pleasure as his tongue gently tickled it. He lifted her torso back up as he pulled her shirt and sports bra off, freeing her pert breasts.

She sighed happily as he began to fondle her, relishing the feeling of his lips on her skin, wishing he would move to her nipples faster, needing to feel his tongue on them.

As if reading her mind, he complied, moving his tongue across her left breast, drawing her nipple into his mouth and gently rolling it around, sucking on it gently, and then moving across to her other breast. Her nipples responded quickly to his tongue, and she moaned in pleasure as he gently bit down on them. He pushed his hands underneath her torso, lifting her easily in his arms and continuing his tongue assault on her breasts.
