The air in the van was beginning to get real musky, what with all the dried fluids all over the boys. The van was also filled with the constant pant of the 5 rottweiler boys who were becoming more horny by the smells every second they remained in the vehicle. Mr. Shroeder was also sweating profusely, and for some reason he couldn't take his mind off of the boys, glancing into his rear view mirror and soaking up their beautiful bodies. ? What was he thinking? Their long slender tongues panting wildly out of their muzzles. Their muscles visibly pushing against their cloths, Bix wasn't wearing a top and Oh Damn hes got 2 more rows of nipples. Bix's face was focused downward towards his crotch which was covered by a paw like hand, but it wasn't Bix's paw, it was coming from behind the seat. Kevin couldn't take it any longer and he needed to touch and feel someone, Bix's scent was just too much in front of him, he slid his paw from the left side of his seat and groped Bix's cup and began to stroke it back and forth. He moved forward and began to lick the side of Bix's neck who gave a low grunt of ecstasy. Joel seeing all of this wasn't about to be denied either and moved behind Kevin and pulled back his pants to reveal his friends wagging tail and butt hole situated right underneath it, he penetrated it with his tongue and licked and sucked on Kevin's cheeks, tail, and as far down into his pants as he could go. His hand paws moved to stroke Kevin's jock cup.Both Kevin and Bix were now grinding their bodies along with every stroke, the noise of panting now joined with low grunts and moans of pleasure from the back of the vehicle. They had just pulled in front of a stop sign just one block away from the station. When the boys couldn't control their needs anymore. Mr.Shroeder turned his body to focus on the orgy that was beginning to take place in the back of his van and was shocked by his feelings of pleasure from this spectacle. Mike quickly understood Mr. Shroeder was beginning to fall victim, and wanted him so bad. He quickly unbuckled Mr.Shroeder's seat belt and quickly pulled him into the back passenger area onto the floor. Mr. Shroeder was shocked by the strength and speed of Mike. He was even more surprised when mike moved in between the two front seats and pulled his pants down his butt freely tasting the open air as well as his short tail and right there in front of him between Mikes Patterned Cheeks, right below his tail was his hole wide and, what was he thinking? FUCK ME! Mike moaned out unable to take it anymore, he wanted his guardian to enter his hole. He wanted to feel his shaft inside him, but even more he wanted that shaft to get knotted inside him. Mr. Shroeder was being driven crazy by these conflicting signals of obeying Mikes command and being repulsed by it. The other boys began to move closer to him Isaac went down to his jeans and began to sniff his crotch whining needfully all the while. Kevin move down to his butt and began to lick and smell his pants in that area, Joel was caressing Mr. Shroeders chest from behind, while Bix began a to lick and slobber all over his face, trying to get his tongue into Mr. Shroeder's mouth. After a last forceful probe Bix found his mark and began to explore the inside of Mr. Shroeders mouth with his tongue, Mr. Shroeder was soon returning the favor. Isaac began to unzip his jeans with the help of Kevin from behind. The pants were slowly pulled down, Kevin, and Isaac were driven madly by his scent and began to lick and suck, Isaac pushing his muzzle down his boxers and sniffing and licking all the way. "Isaac come on over here and get me ready for him." Said Mike with a smile. Isaac looked up from were he was and smiled, moved over to Mike, bent down and then began to salivate and lick deep into Mikes hole. Mike gave out a few deep moans of pleasure as Isaac's tongue explored inside. Mr.Shroeder was watching in a delirium of pleasure and euphoria as Isaac probed the Doggy Boy's anus, and the other boys were lapping at the growing patches of fur on his body. He felt a sharp pain from his crotch that was now screaming to be used, he slowly slid down his boxers to reveal a reddening pole that was getting more pointed by the second, Kevin, Joel, and Bix immediately moved down to his member and gave it copious amounts of lubricant for the task at hand. Isaac finished and jumped on Bix and began to hump and deep kiss him in the passenger seat. Mr. Shroeder feeling an uncontrollable urge to fuck moved towards Mikes inviting entrance. With his still forming paw like hands he grabbed a hold of Mike's ass and thrust his member deep into Mike's hole. Mike gave out a yelp, and then a moan as the pain subsided and was replaced with extreme pleasure as the new Rotty began to use his new equipment, thrusting into Mike again and again until finally they were tied and he released his last remaining human seed into his ward's ass. Lance (Mr.Shroeder's first name) was now occupied with licking himself clean of all the fluids that covered him. "Now its your turn." said Mike with a smile, removing his jockstrap he took his red member out and motioned for Lance to lick and suck on it, while Kevin lubricates Lances behind. Mike thought that Lances grayed and rusty markings were beautiful, he now had 4 extra nipples down his chest and a strong build of muscle, with a slight whitened beard on his muzzle, his hot red member was just a little smaller than Kevin's monster, he also has a long and strong tongue that the boys really enjoy(as does the new Lance). Mike positioned behind his old Guardian and then thrust his red doggy cock into his new pack mate. Bix and Lance were exploring each others mouths again and Kevin was slurping and lapping at Mike's hole, Joel had positioned himself underneath and was sucking on Lance's new Rotty balls. Isaac meanwhile was sucking on his own member in the right side passenger seat. He just noticed out of the window that someone was coming over to the vehicle. He quickly alerted the others, Mike and Lance were tied so they slowly moved to the back seat. Mike also had an idea, maybe if Isaac pretended to be like a normal dog the person in question wouldn't bother with the fact that he isn't shaped like a normal dog. Isaac was trying to hide most of his body, he rolled the window down and allowed the person to approach, giving and innocent pant and smile as well. Isaac noticed who it was coming near. A freshman boy on the school swim team, his name was Greg (they were a block away from the community pool and swim practice was in the morning) Greg had noticed the van and recognized it as Mr. Shroeder's he was concerned because it hadn't moved since he had walked 2 blocks from his house. He approached and noticed that there was a Big Rottweiler sticking its head out and smiling at him "Must be Bix" he thought. He got closer and noticed that the dog looked to be alone. Isaac couldn't wait Greg was getting closer to the window and he wanted to give him a huge slobbery kiss. He could just imagine fucking Greg and watching his beautiful swimmer muscled body become a hot Rotty boy, seeing those hot nipples spread down his chest and a sexy muzzle, he wanted it so bad whining more and more as Greg got closer. Picturing through his close a throbbing red member slick with juices and a cute doggy butt with a wagging tail entreating you to enter his hole. He pictured him getting on all fours and thrusting his behind in your wet nose, panting his excitement and need. Greg approaches the window and greets Isaac "How you doing buddy?" Isaac immediately went up and began to lick and slobber thereby beginning to infect Greg. Greg tried to push Isaac away only in jest to get him to stop slobbering all over him. Isaac was more determined than ever and his hand immediately grabbed Greg's shoulders and thrust his tongue into Greg's mouth and began to explore it vigilantly. Greg fought it and continued to fight until he broke free of Isaac's grasp. "What the Hell!" he yelled as backed away from the van. Isaac let out a laugh of excitement! Which was mistaken by Greg as some kind of prank that, now that he heard the voice Isaac was putting on. He was furious that he fell for this new gag and went off to swim practice, mad as hell at Isaac and his friends. Isaac really hated the fact that he missed his chance, but he really loved the way Greg tasted. He did not want to give up yet, and went to the back and asked Mike if he could stay here and infect the community pool. Mike, seeing Isaac so determined said he could, but every member he makes must share the love with the pack later. Isaac grinned and to show his loyalty bent over and pleaded that Mike should enter him again, Mike moved down and sucked and licked his own cock to get it ready and lubricated Isaacs ass as well, then he thrust his red rod into Isaac with a yelp and moans of pleasure as he pumped away.
