Jennifer excused herself for a moment to go back on the computer. She wanted more. Jennifer made additional changes to her boyfriend.
After pressing enter Jeff's face begun to extend from his nose and mouth. His face started to have more feral dog features as his human hair dropped down to his face and it became spread all over her face forming thicker patches of fur. Jeff was starting to look like a very realistic looking fursuitter with a dog's face and a body than a human with dog’s features. He was still able to communicate with human-like speech with vocals coming out more bark-like. The transformation was now more on the animalistic and feral side than humanoid and anthropomorphic side. Making Jeff a big dog with anthropomorphic features than a human with dog features. His rounded human-like teeth were looking more sharp and canine and his mouth looked like a maw. Jeff was now breathing with his tongue out of his mouth like a dog would have done in a sunny day. The eyes and the ears moved and twitched as he turned his head.
The last big change was the bulging penis inside Jeff's pants as Jennifer asked Jeff to remove all his clothes. The regular human cock was increasing in volume and in height. It was getting more red tint of color as Jeff's junk was reflecting her current transformation. Jennifer looked at the massive animalistic meat in awe as it was straight out of someone's kink cave. The hairy balls, the sheath and half-erected dog cock crowned the transformation for Jennifer. She had to have that thing inside her.
"Jeff. You think you could fuck me with that prick of yours?" Jennifer asked as she licked her lips and begun to worship it. Sniffing it's musky tip and shaft.
"I- I- could bu-bu-but wou-! Woof!" Jeff barked as Jennifer was too distracted by the red rocket and was sniffing it’s animalistic scent. Jennifer was toying with Jeff and didn’t touch his dog cock as it begun to extended in size.
“Je-je-jenni-woof. I-I-I get so horny when yo-you do that to me…” Jeff whined like a dog as the cock was getting itself ready to it’s full length size.
Jeff couldn't hold his excitement and like a dog tried to put his paws in front his face to hide his shame. This made Jennifer more moist as in front of her the cock grew in size like a skyscraper that was being build. It was going past her forehead until it dropped a small leak of semen on her nose. Jennifer could imagine that Jeff’s new red rocket would go past her throat if she let it inside her mouth. She had to put it inside her vagina. The tension was real as both of them gasped for air. Jennifer and Jeff were breathing heavily as the warm air pushed from their lungs. Both of them looking at each other in silence without saying a word to each other. Jennifer wanted to go down so bad that she teased Jeff by blowing air from her nostrils on to Jeff's balls.
“Jenny! Please! I’m too sensitive right now!” Jeff pleaded as his cock swung up-and-down.
Jeff was still able to maintain his cock’s hardness even if Jennifer hadn’t done anything to it. She had only blown air from her mouth and nose to his balls and cock. Jennifer moved herself more closer to Jeff and really wanted to sniff his balls and hovered her jaw on top of his perineum. Jennifer pushed her tongue out and slowly went up Jeff’s body without touching anything. Jennifer’s sensual arching movement was a tease to Jeff. Jennifer showed Jeff what he was about to get. She posed her petite body for Jeff to make him even harder. Jennifer’s slender waist, hips and petite breasts kept Jeff’s cock hard. He couldn’t look away and couldn’t touch her. Jennifer got up to his ear on top of his head and whispered in Jeff’s ear.
“Stay still and don’t do anything. Enjoy what I’m about to do to you.” Jennifer told to Jeff.
Jennifer pulled her hair back, lowered herself back down and gave a taste test on Jeff's dog cock's tip. Jeff huffed air as it made him sweat. A tip of Jennifer's tongue made contact with the canine cock. It had a salty taste which was expected. Jennifer smiled.
Jennifer was gently pushing her lips gradually deeper down on Jeff’s cock. Jennifer was only able to take the tip inside her mouth. But it was enough for Jeff who tried his best to contain his happiness.
Jennifer was in charge and she felt that it was time to do it. Jeff leaned back and huffed. He tried his best no to released his balls too soon. He wanted to respect Jennifer and keep his promise to her. He was enjoying but doing nothing felt hard. Jeff’s heavy breathing was so audible that it made Jennifer more wet. Jennifer wanted to do it raw and swirled her tongue on top of Jeff's tip while her lips had enveloped the small portion of the whole cock.
The basement became quiet as only sounds were coming from the old computer’s fan and from Jennifer and Jeff. Jennifer begun to moan as she was now in trance. Having to suck her boyfriend's canine cock had made her lose her composure as she wanted to just continue. Sucking deeper and deeper until it the salami was hitting her back throat. Jeff had to put his paw on his face as it was getting too hot for him to handle. He was submissive and knew that Jennifer would hate it if he now unleashed his load on her.
"Jenn... Please… No..." Jeff pleaded. "You are making me… NNNGGHHH!!!"
Jennifer smiled at Jeff while she hold his cock in her mouth. Jeff was struggling as his tail was wagging like crazy and legs begun to tremble. Jeff was nearing his edge and it took him great mental fortitude to hold back. Jennifer lifted her mouth leaving a visible lukewarm saliva string as her lips and Jeff's cock departed their ways.
"I guess now it's time. Jeff. Got any condoms?" Jennifer asked.
“Jenny… They… They are in 'there'." Jeff panted while pointing her paw on the nightstand.
The condom package looked weird as it had changed to reflect Jeff's transformation. Jennifer had no time to think about the fact how dog-men had their own brand of condoms and quickly inserted the condom on to the canine’s cock. Jennifer took the lube bottle and emptied it out on Jeff’s cock and put some of it on herself just to be sure.
Then, she did it.
Jennifer ascended down on the dog boy's erected cock. It felt amazing yet weird as the size was bigger than human's. Jennifer found it difficult to go all the way in as she had to hop like a rabbit on Jeff's cock tip. Dipping the wet vagina fluids on top lubricated condom. Jeff’s tail and legs trembled even harder as Jennifer moved faster.
Jennifer went even deeper down on Jeff’s cock and got it half way in inside her vagina lips. Both of them beginning to enjoy the canine sex together. Jeff was still struggling to keep his cum inside him as he watched Jennifer bouncing on his rocket. He wanted to push Jennifer to go past his knot but he was told to just enjoy it. He was a good boy and good boys listened to their master’s orders. He enjoyed it as he was a virgin and getting your virginity taken by a girl she loved was the best thing in his world. His sensitive dog cock was getting it's loving petting from a girl he loved.
"Jeff!" Jennifer shouted. "Come inside me when I say the word..."
"What word?" Jeff asked.
Jennifer went quiet and hopped on Jeff’s cock with faster pace. Jeff had no time to think but he waited for the word.
“Jenni-woof! Jenni-woof, I love you! Jenni-woof! What’s the word? Jenni-woof!” Jeff barked.
Jeff felt the pressure getting harder. Jeff wanted to release his doggy baby batter inside Jennifer. No, he couldn’t. He had to keep it inside because-
"You are such a-" Jennifer smiled and slammed her bottom half into Jeff as deep as she could.
"Good. Boy."
Everything moved in slow motion all of a sudden.
What did Jennifer just call him.
Jeff’s brain wasn’t able to process the information.
What?
Was he?
What did she call him?
Was he a…?
A Good Boy!!??
“RRRWWWAAAAAAAARRRHHHHHHHH!!”
Jeff let out the most feral and brassy growl out of his lungs. Jeff pushed his cock even further inside Jennifer and knotted her as he came inside her with force. He released so hard that the condom broke from it’s tip and all the doggy liquid released inside Jennifer’s womb. The tight reverse knot hug inside Jennifer’s abdomen made her orgasm. She wasn’t expecting this feral attack from Jeff. Jennifer felt the canine knot expanding inside her as her belly was expanding from the semen that came from Jeff’s balls.
The warm liquid gushed into her vagina as it felt weird. Jennifer had to lie down as his legs felt weak. The knot wasn’t letting go of her as Jennifer panted and tried to hold her head. The sex had trigger something inside her as there was another orgasm from the knot still being stuck inside her.
Jeff had passed out as he now slumped on the floor. Jennifer gave kisses to his maw and licked his tongue like a dog.
“Jeff… I love you. You silly boy.” Jennifer smiled and then passed out on the floor.
A dark silhouette watched from upstairs of the basement floor as they slowly ascended to the basement to see what a mess Jennifer and Jeff had made together.
