Slade rolled up the parchment of his sister's design and placed it back into it's scroll case. The road had become rocky and the coach's wheels seemed to find every rock and hole in the road making reading almost impossible. Joy was leaned into one corner of the coach fast asleep dispite the bumpy ride. Fiona sat directly across form him looking out the coach door window at the landscape as it went by. Fiona looked over to her brother noticing that he had put the drawings her sister made back into their case.
	"Well what do you think of it?" Fiona said as playful smirk came over her face. "Joy spent many nights and days dreaming up that contraption. Do you think it will work?" 
	Slade looked up from the scroll case into his sister's eyes. "I don't know. It isn't impossible to make or use..." Slade looked back at his younger sister sleeping in the corner. "But it isn't very practical. It would be too expensive to build, it's extremly complex to assemble, and it would be too bulky to carry or move quickly." Slade looked down to the scroll case again. "I know she worked hard on this design, I don't want her to think that her efforts are being dissmissed without being given a fair chance."
	Fiona giggled softly. "Slade my dear brother, you totaly underestimate our little sister. Joy might get a little teary eyed now and then, but you'd be a fool to think that was a sign of weakness or giving up. That skunkette is just as stubborn and deternined as you are... maybe even more so."
	Slade let out a sigh. "Perhaps you're right." He looked over at Joy again. "How can she do that? How can she just sleep through all this bouncing about?"
	"She stayed up with you all night working on those damned spiders you two were milking for their venom remember?" Fiona said. "I'm supprised YOU haven't nodded off. You'll need your wits tomarrow you know."
	Slade let out a frustrated sigh. "I know, I'm just too tense to get any rest. Well, that and the coach's constant bouncing doesn't help either." Slade ran his hand through his hair as he shook his head.
	Fiona thought for a moment, then moved from the seat across from her brother to the seat right next to him. "I think I can help you get that much needed rest. Can you keep a secret?" She said. Slade looked at her and nodded. "Good." Fiona said. "Just close your eyes and relax, try not to worry about the rest of the world for the next few minutes and follow my lead ok?"
	Slade did as his oldest younger sister asked and closed his eyes. He did his best to loosen up like she had instructed. Fiona had given him massages in the past after training exercises and workouts. Fiona's hands would melt away any pain and fatuge that he would feel. It was much to Slade's suprise when he felt something warm, soft and wet press against his mouth and something soft and slick slip into his mouth. Slade opened his eyes and to his shock, found his sister was kissing him very deeply in a way sisters were not ment to kiss their brothers. Slade tried to speak, but Fiona's tounge only slipped further into his mouth.  He tried to back up but his head met with the wall of the coach and Fiona simply followed with him. Slade felt her hand gently rub over his crotch while her other hand Pushed on his chest, pinning him to the coach wall. Fiona held her brother like this for several seconds before letting her tounge retreat back into her own mouth and letting her brother and herself gasp for air.
Slade looked at Fiona in total disbelief. "Wh-what has gotten into you?" Slade said, still shocked by his sister's actions. "We are sibilings, we shouldn't be doing this!"
Fiona put a finger over her brother's lips. "Shhhh... If you make too much noise you'll wake up Joy." Fiona gently gave her brother's manhood a little squeeze. She could feel her brother growing in her hand. "As I promised, I'm going to help you get some much needed rest. I need you to trust me Slade. I promise you when I am done, you will sleep soundly for the rest of the trip." Fiona looked deep into Slade's wide eyes. "If it's one thing a female can do well, it's putting a male to sleep in a matter of minutes."
Slade interupted, "But you're my sister Fiona."
Fiona smiled and said. "Yes, but I still know what it takes to put a guy to sleep, and you are a guy. Put out of your mind our relation, and just concentrate on the raw mechanics of me being a female." Slade tried to protest, but Fiona moved in and kissed him again. Again she let her tounge wriggle it's way into Slade's mouth. Fiona's breathing got heavier and more passionate as she pressed her breasts against her brother's body. "Come on Slade." Fiona thought to herself. "Come on, touch me. Grab a body part and give it a squeeze." Her tounge continued to explore Slade's mouth and tounge. She gave her brother's cock another firm but gentle squeeze as she rubbed her breasts and thighs on his body.
Slade's mind was racing. His animal instincts were urging him to grab hold of Fiona and fuck her hard, but his mind kept screaming at him that this was his sister. After several seconds of Fiona's tounge and her phermones flooding his bloodstream, the two parts of him reached a compromise and Slade allowed his hands to carress Fiona's ass. Fiona lifted her tail, signaling to him that it was, "Ok" for him to continue fondleing her. The sibilings continued to kiss and explore each other working themselves into a sexual frenzy.
Fiona flicked her head back gasping for air as Slade burried his muzzle into her cleavage. Fiona rocked her hips faster and harder as she continued to dry hump her brother. Slade's hands slid up his sisters back and came to the front giving Fiona's D cup sized breasts a firm squeeze.
"I think you're ready Slade." Fiona said through heavy breathing. "Lie back and let me get a taste of what you've got down here." Fiona gave Slade's cock another squeeze then drug her hand to the belt buckle that was holding his pants closed. Fiona kissed her brother deeply as she worked the buckle open and began opening the fly to his pants.
"What about Joy?" Slade said. His eyes darted from his sleepig sister and back to down to Fiona as she looked up at him while fishing out his manhood. "I-if she wakes and sees us..."
"Shhh..." Fiona quietly gestured placing her lips at the shaft of her brother's cock as she made the noise. Her hot breath heated up the already warm flesh. Fiona let the saliva in her mouth pool under her tounge and she ran her tounge up the shaft of Slade's cock from the balls to the tip in one, slow, sexy drag. Her saliva left a glistening trail along the bottom side of his shaft. All Slade could do is let out a sigh as Fiona let her tounge dance around the tip of his cock allowing the saliva that was pooling under her tounge to now overflow and dribble over the head. Fiona softly inhaled a deep breath, then devoured her brother's cock down to the hilt. Slade felt his sister's tounge slide over the head of his cock, then felt what he thought might be her tonsils slip past the sides of the head of his cock. He reached the back of Fiona's throat and she made a swallowing motion with the muscels in her throat to get his cock to start the journey downward. Fiona's nose bumped into her brother's abs and her chin pressed up against his twitching ball sack. Slade let out a soft groan as he did his best to not explode into his sister's gullet. Fiona kept her brother buried deep within her throat letting her tounge wriggle forth to tease her brother's balls. Slade could bear no more, he whimpered out his sister's name as he erupted into Fiona's stomach. Fiona kept Slade down her throat while she felt his cock throb and pulse as he emptied his balls into her gut. Fiona got curious as to what her brother might taste like and slowly slid her brother out of her throat and into her mouth. One final spasm sent a few drops of Slade's cum squarely into the center of his sisters eager tounge. Fiona milked the shaft with her mouth and hands, sucking out another drop or two before releasing her brother's now limping cock and giving the sample she had collected a few swishes in her mouth before gulping it down. It was somewhat salty like melted butter with a slight sweet under taste, it had a texture similar to thick cooking oil or shampoo. She felt it ooze down her throat to join the rest of Salde's ill fated future pups.
Slade looked down at his sister. His breathing was coming down from heavy panting, to a more relaxed rhythm. Fiona gently put her brother's cock back into his pants and sealed up the belt. "There, that wasn't so bad now was it?" She said looking her brother in the eyes, which looked like they were getting heavy. "Just sit back and relax now Slade." Fiona said in a soft voice. "We'll be in Rosenburg before you know it."

"Slade! Slade wake up!" Joy's cheerful voice pulled Slade from his slumber. "We're here, we're here!" Slade opened his eyes to the busy streets of Rosenburg. The coach was still and the sounds of busy city life buzzed around him. "Get out of there sleepyhead, or the coachfurr's gonna charge you rent!" Joy gleefuly said. Slade steped out of the coach and was approached by his sister Fiona.
"I got us two rooms at the Two Foxes Inn." Fiona said matter of factly. "Here's your room key." Fiona handed him a key with the number 8 engraved on it. "And this one is for us gals." Fiona dangeled another key infront of her brother with the number 7 engraved upon in. "The inn staff will bring in our luggage. I suggest you get to the town hall and meet with the governor so that we can get the details of tonights work ironed out." Fiona didn't skip a beat as she began to reign in Joy from wandering away into the city streets.
"Did... Did it even happen?" Slade thought to himself. "It must have been a dream! Fiona would never... would she?" Slade started walking in the direction of the city's town hall to meet with the governor with a pondering expression on his face. Fiona watched her brother shuffel off down the street. A slight smile crossed her lips as she looked down to her belly . It made a soft gurgel noise, as it digested the last of her brother's seed within.
