Luke's upper wolf costume continued to stick to his skin, slowly transforming him. Yet, with Jake pleasuring at his rear with his long agile tongue, the costume accelerated its pace in synch with the erotic experience. The fur slowly glued itself to his skin, sprouting a silver grey toned fur with a white tufts of fur over his chest as the typical feral wolves. teeth extended itself to sharp canine fangs without pain, but a consistent building pleasure. That tongue of Jake was most definitely agile, a wet nose massaging his tailbone up and done; while his wet tongue salivated his entire toned ass. Luke let out moans, his tongue grew longer bit by bit as his saliva flowed along his mouth.
An idea came on his mind to increase his please. If Jake were to wear the bottom half of his Wolf-taur costume, Jake would definitely grow in size and add mass to him. Like steroids to jocks, huge muscled bulk bodies. It might even add to this.
"Hey Jake...." Luke said before he let a moan slip out his slowly protruding canine muzzle.
"Yeah Luke..?", Jack said.
"How about wearing this wolf costume I got?" Luke responded.
"What? I'm already wearing a wolf costume if you haven't noticed man." Jack said followed by a deeper lick. His saliva coated his anus enough, so he could slowly penetrate his tongue a little inside him.
"This one is different. Look, right now you stand about half a normal persons height as a wolf. Errrr.. like 3'3'' or 3'5" i think? The costume clerk told me this costume is about 4 feet, but buffed up." Luke insisted on Jake.
"Buffer and taller eh? Sure! Put it on me now!" Jake excited. He'd be the top dog now he said to himself. He pulled his tongue out of Luke and backed away a little further away for Luke.
Luke went over to pick up bottom half of the wolf-taur costume off the floor. As he crouch down, he look behind over to Jack, to notice his canine cock's tip pocking out of his sheath. He was excited, he panted and his tail went side to side like a happy household dog. Even an instinctive happy bark came out of him. Luke could only smile at him as he over his attractive eyes. Luke's costume, even though only the top half over his costume, had started to grow him a happy trail of fur down his belly. His nails turned black, pushed out into claws, and his nose slowly turned black and a little cold. Evidently he started to take in the pheromones both young men were producing in the room.
"Common, hurry up, i can't wait for this. I want to get bigger like yesterday!" Jake yelp eagerly.
"Okay buddy", Luke said as he helped Jack's hing legs get inside the tight latex costume. Adjust the folds over his torso, pulling it further like a sock.
"Wow, i can already feel growing already" Jack was right, his back hing legs already grew thicker with additional bone mass and muscle.His pack paws even grew as big as a horse's hoof when Luke pulled the costume over his chest. Jack's body grew larger than an Irish wolf's hound body. In fact his back legs were as thick as a professional body-builders muscled quads.
"Must be the additional hormones there buddy" Luke smirked to Jack. By now he was fitting Jack's front legs over the. Jack sneaked his lips over his muzzle over Luke's lips to lock into a kiss. His wolfy tongue slips into Luke's own tongue, exploring newer sensations Luke had missed out. So this is how it feels like? Intense, he moaned softly.
By now Jack's jumped over behind the sitting Luke, to stick his tongue out up his ass. Penetrating it deeper rhythmically. His canine cock came out completely as he was getting off oral rimming his buddy, holding his right paw over his waist to get him easier. Luke curled a moan out at his surprised penetration, slowly standing and leaning himself over a wall. Looking down on his waist, the happy trail spread over his groin. His balls were forming a furry sack, he could feel now his penis changing as well.
"Hey Jack, look down over my toned ass man." Luke hinted.
"Eh?" Jack half. Noticing Luke's newly formed furry sack pushed him further. Oh it was a hint? He jump over Luke leaning on the wall to have both front paws around his waist for a steady form. By now the second wolf skin had fully made Jack into a thick muscular hound pushing 4 feet tall standing on his four legs with added strength. His agile think neck bent under his rear, tilted to start licking his furry ball sack and changing between sucking.
Luke shocked on Jack's rush, yelled out as stronger pleasurable moan. The licking over his ball sack accelerated the costume's progress. Within a couple of seconds, Luke's canine dick pop out fully. Matched with a rod length and to swelled cred balls. Already forming pre-cum. Instinctively by nature, Luke pulled down his pulsing canine dick underneath him closer to Jack's muzzle.
Then.....
