Upstairs, Mike stirred slowly from his slumber. Something felt really, really good. He knew Danni was next to him and could feel her naked body pressing gently into him. Wait, that wasn't right, she was on top of him he realized, as he felt something warm pressing down on top of him. He slowly opened his eyes, and she was staring at him, smiling as she lowered her lips to his. She arched her back and lifted her hips, pulling him out of her and then slowly lowering her hips and plunging it back in.

"You are the fuckin' man"

"Wow," he said finally, "This is definitely a great way to wake up. I could get used to this." He arched his neck and moaned loudly as she slid up and down on his pulsating shaft.

"I didn't think you would have any complaints, lover." she said quietly, lifting her hips and rocking them gently back down on his cock, sliding slowly down every pleasurable inch. "Oh God, you feel so good inside me," she admitted.

She lifted up again and turned over, lying on her back in his bed. He followed her lead and turned over, pulling up between her legs. He lowered his lips to her neck and began to nibble softly, tenderly moving up and sucking on her ear and thrusting gently back into her. She smiled and moaned as she felt him re-enter her. He reached down and hooked his arms under her knees, tilting her hips easily upwards so he could thrust straight down into her passage.

"Fuck her until her hips break."

"Oh, wow..." she said, suddenly beginning to like this new position. "Oh, Mike, that's, oh yes, do me harder."

She had to close her eyes in pleasure as her brother continued to plunge in and draw out of her, his eyes closed as well and locked in concentration, enjoying every cell of her body that he could feel.

He continued to thrust in and pull out, establishing a steady rhythm and bringing her closer and closer to ecstasy. She looked down and saw his shaft pumping in and out of her pussy, and the sight of it immediately pushed her over the peak down into the abyss.

He felt her pussy tighten around his cock which triggered his own orgasm. A wave of ripples pulsed up and down his organ as she gently bucked to and fro beneath him, small gasps escaping from her lips.

He began emptying himself into her, pumping quickly up and down into her tunnel. She squeezed with her muscles and he gasped as the last pulse of his orgasm thrummed harder than he'd expected, as they collapsed into the sheets, spent.

Unknown to them, the door opened in the middle of their love-making and then closed quietly a few minutes later after they had finished.

It was just as Beth had suspected. He was having intimate relations with both Danni and Emma. She'd have to talk with Sarah about this as well. This was very puzzling behavior, but she was also concerned about the way it made her feel. She was determined to figure out just why it made her breathing erratic, her pulse race and finally making her feel faint. During and after, she also noticed her privates all wet.

Beth was as innocent as she was beautiful. She understood every aspect of the reproduction process from the clinical perspective. How her own, as well as all female organs worked and knew perfectly well what was causing the wetness. Her scientific mind just hadn't worked out what she was feeling when watching her brother and sister.

Then thinking about it, it dawned on her that Sarah wouldn't know what to do, why should she ask her? Maybe she should just go straight to Mike. Maybe he could explain what was going on without embarrassing her. That was the best choice, she decided, and headed back to her room. She found herself more curious than disgusted. What caused two of her sisters to start lusting after their own brother? It was a quandary, and one she was determined to solve at all costs, or so to speak.

Mike showered after his morning encounter with Danni and put on some jogging clothes, determined to start working out again. He pulled on his shorts and headed downstairs carrying his running shoes. Emma and Sarah were sitting on the couch as he came into the living room. Mike eyed them both nervously, wondering why their smiles were, one; so wide, and two; mischievous looking. Like the house cat that had just eaten your favorite canary.

"Uh, m-morning." he stammered nervously, and then asked, "What have you two been up to?"

"Just talking about all the 'ins' and 'outs' of the trip," Emma said, who giggled when Sarah elbowed her.

"Oh, yea." Mike said, looking down. "That was some trip. It was fun."

"For some more than others." said Sarah. Emma punched her back.

"Fuck them both right now! They know too much!"

"Can I go running with you?" Emma asked, smiling innocently.

"SAY YES! SAY YES DAMN YOU!"

"Uh, sure," What the hell else was he gonna say? 'No I don't wanna watch your ass bouncing along in front of me?' He shook his head clear from the image, "Of course you can, Em,"

He turned and looked at Sarah. "You wanna come get a good workout too?"

'Oh no.' he thought. Coming out of his mouth, that comment showed no resemblance to what had been rattling around in his brain just seconds before. Sarah wasn't about to let that one slide without a little turn of the knife.

"No thank you sweetie," she responded with a wink, "I'm sure I'll be able to find another way to get a good workout later."

Mike blushed three different shades of red, and you could have lit a match with the heat coming off his face. They had to have talked to each other. He briefly wondered if the jig was up, and he was going to be in a world of hurt in the very near future.

Emma went to her room briefly to get her running clothes and quickly returned with them in her hand. Mike was sitting on the couch waiting, looking down and hoping that no one would say anything to cause him any further embarrassment.

Emma shot a look at Sarah and winked. "Sarah, can you help stretch me out a little before we get started?" Sarah barely contained a grin as she nodded and moved toward her sister to assume whatever position was expected of her and help in whatever manner Em had in mind. Emma lifted a leg and placed it in Sarah's arms, leaning back against the wall. Sarah brought herself closer and began to push upwards on her leg.
