Thank you kindly Guest for your review, so here's another chapter. It is a tad long, but I think it's better to have one long chapter that has explanation than shorter chapters without things being explained.

-Bolt-

I woke up feeling sluggish and still sleepy. I was cuddled up next to Mittens who was snoring softly. I felt my balls tingling with pain and I groaned in pain. I looked out the window and saw that night had fallen already.

So I stood up and found my legs to be weak and wobbly. Falling back down stole Mittens from her sweet dreams. She jumped up with a, "Huh?" and a, "What?"

"Sorry Mittens," I told her, "I was trying to get out of bed and realized that my whole body aches."

"You did show me a fun afternoon Bolt," she slowly reached over and lazily scratched behind my ear. My tail wagged and my tongue stuck out in the amazing sensation, "Thank you for being my first," she smiled.

"No problem. Ya know, I'd love to do it with you again," I suggested.

"I'd like that."

"Maybe... maybe if things go right, Penny can join in."

She stopped scratching my ear, "I dunno. I think that Penny wouldn't be too keen on wanting a threesome with her dog and former cat."

"You never know."

"Penny! Mittens! Bolt! Time for dinner!" Penny's mom called out.

Mittens clambered out of bed and I saw a large stain where she laid. I sniffed it and it had a musky odor and I concluded that it was semi-dry sex juices that Mittens and I blasted all over the sheets. Mittens groaned and I looked.

Cum oozed out of her hole and down her leg, "Coming miss Lucida! I just have to change right quick!" Mittens called out to her.

"Okay, but hurry up before supper gets cold!" Lucida called back with her usual chipperness in her voice.

"I have to drain what's left of your semen into the toilet. You can go ahead and go downstairs. I'll be right behind you," she smiled at me.

"Um, okay," I smiled back, "Don't take long. The sooner we eat, the sooner we can come back up for round two," I told her as I stiffly got out of the bed when I jumped down, my joints cracked and locked.

Despite the discomfort I stretched my legs and the rest of my joints popped. The cracking revived y muscles and allowed the energy to flow throughout my body, "I'm going to go see if Penny's okay. I haven't seen her for quite some time."

"Sure thing," Mittens said as she grabbed a pair of sweatpants and a T-shirt.

I went to the door and saw that it was closed all the way. Knowing how to open a door, I lifted the top half of my body onto the door and used my mouth to grab hold of the knob and twist it. The door clicked and I pulled back and dropped back down to my feet. The door opened a few inches; enough room for me to pry the door all the way open with my nose.

The hallway was lit with only one light as I walked with a little pep in my step. At the end of the hallway was Penny's room that had light streaming from under the door.

I push past the revolving barrier and the sight revealed to me stole my breath. Penny was on her bed naked. Not only that, she pushed her but up in the air with her feet whilst her fingers were in her hole, "Ou fuck Bolt," she moaned to herself, "I love it when to fuck me."

When I backed out, the floor boards creaked and she snapped out if her fantasy. She looked at me with such bewilderment and befuddlement and I stood in bedazzlemenat the thought of my Penny having fantasies about me.

"Bolt!" she snapped her blankets over her body and tucked her head under them, "I think you need to leave. You weren't supposed to see me like that."

"Penny?"

"No, Bolt! Go away!"

Her words hurt me and I just wanted to cry, "I'm sorry Penny," I whimpered and headed out the door with my tail dragging behind me and my ears drooping on either side of my head.

I moped down the stairs and past the kitchen. I drew the attention of Lucida and she stepped out to talk to me, "Bolt, what's wrong?"

"Nothing that you'll understand," the situation was actually completely understandable for anyone, I just didn't want her to bother Penny about what just happened.

"Are you sure? I can help."

"Just leave it alone."

"I can't stand seeing my little man be all sad," I felt her arms wrap around my stomach and my feet disconnected from the floor. Lucida took me into her arms. She was very strong for someone her size.

"Over the past months, I've gotten a bit bigger. The last time I went to the Vet, I stood three food four, weighing in at almost a hundred pounds.

She walked into the Bay Room. The bay room was a room mostly comprised of tinted windows. Tinted so that no one could look in, but we could look out. I saw the stars twinkle, twinkle, in the sky. Oh how I wonder...

Lucida sat down and placed me on her lap, "You know, I've noticed that you haven't been yourself these past couple of months," she scratched behind my ears and my eyes rolled back into my head.

"What makes you think that?"

"Well, Rhino and Mittens have turned human and I think that you might feel a little left out."

"I feel as though that's just the first part of your theory Miss Lucida."

"I've seen the way you'd act around Penny, Bolt."

"I do love her Lucida, but our love cannot be. She's my person and I'm just a dog."

"You know, I've done a little digging on that stone the government snagged from our house."

"How'd you do that?"

"With being the mother of a movie star, you get connected. Now, as I was saying; the rock had a radioactive substance called Rithonium. It's a substance that turns any kind of organic being into that of its surrounding; or at the very least, take I some of the characteristics. There's also another thing about it, if one gets enough of it, they'll fully turn into that thing."

"Oh I get it. It explains Mittens and Rhino. They were right next to the rock in the back yard, weren't they? I just found a small one at the park behind some bushes."

"Yes. Exactly."

"So why do you bring it up?" I rolled onto my back and she scratched my belly.

"A friend of mine in the government is going to swing by to drop off a gas synthesized from he rock. I was thinking of giving it to you."

"What does 'synthesized' mean?"

"It means to make from something," she smiled, "I wanna give it to you because Penny loves you and you love her. If you get more of the Rithonium in you, you'll turn human."

Just then, a flash of black jumped on the couch and we both flinched. We looked and saw Mittens in her cat form, "Talk in dog Bolt," she told me.

"What did she say?"

"She wants to talk," I told her before getting back up and sitting in front of Mittens, "What is it Mittens?" I spoke in dog to hide our conversation.

"There was a mouse in the bathroom and my firsts instinct of course was to chase after it. When I thought about being a cat, I turned into one. Isn't that weird?"

"Why don't you want Lucida to hear us?"

"For one, I can't speak like you obviously, and also, this is kinda embarrassing for me."

"Why not switch back?"

"I already have, but I switched back. I want to make love in this form with you. Just to try it out."

"I'm game. What do we tell her?"

"We can go to the meadow," she suggested.

"We'll go after we eat, okay?"

"Okay," she smiled.

"Care to tell me what's going on Bolt?" Lucida asked and looked to Mittens for confirmation.

Mittens nodded and I spoke, "Mittens figured out a way to transition in and out of her human form," I smiled.

"Okay, now it's official. Things are now down right weird and freaky."

"Wait!" it hit me, "Where's Rhino?" Mittens meowed in agreement.

"He's still at work. He's a workaholic I tell you."

"That sucks," I drop an head then hear movement outside which perked it back up, "Someone's at the door."

The door bell rang and I jumped off the couch and run to the door. I bark loudly until Lucida briskly walked up behind me, "Bolt! Sit!" I sat at her sudden command still bark, "Oh shut up!" she snapped and I whimpered in silence.

She pulled open the door, "Hey Stan. Sorry about him, he's still in training somewhat."

"Hello Lucy and its fine. My dog does the same thing every time the doorbell rings. He even does that for the phone as well."

"Come on in," she stepped aside and a man wearing a black suit with a silver briefcase came into the house. I sensed that he wasn't very trustworthy and I growled at him.

"Wow," I noticed a bit of an accent from his voice, "He's a big one, ain't he?" he knelt down in front of me, "How old is he?"

"He's only six."

"He also has a wonderful coat, he does. I think that he's just simply marvelous. Especially since he's one of the last few of his kind," when he said that, I felt heavy all of sudden.

"I know, but look at him now," Lucida slowly go to her knees, "Now you've made him sad. I just got him out the dumps a few moments ago."

"Ah, dogs can't understand human speech. They're too stupid to."

"Hey!" I spoke, "I resent that!"

Stan fell back onto his ass and dropped his briefcase, "H-h-he ca-can ss-spea-spea-spea...?"

"Mhm," Lucida smiled, "He's smarter than you think," she gloated for me.

"Yeah, I can see that," he was shaking and sweat fell from his brow, "I did not know that he could talk. You didn't tell me he could talk Lucy."

"I wasn't going to and I expected him to stay quiet until you left," she scorned me.

"You know I have to report this to my boss."

"It's in my rights that I don't have to give him up."

"We can buy him from you. That's where I was going with this."

"No, you can't buy him. And even if this family were to sell him, that decision isn't up to me, it's up to my daughter. It's her dog."

"Can I speak to her?"

"As her mother, I wish for her happiness to be intact. Having Bolt as a companion does so and I have to protect the very things that makes her happy. So Im going to say no."

"The government will know of this, that I promise you Lucy."

"Get out of my house Staniel," Lucida stands and opened the door wider.

Mittens came in meowing, "Does the cat talk as well?"

"No, it's just a cat."

"Don't transform in front of this guy," I barked to Mittens.

"Why not?"

"He wants to buy me from Penny and I don't want any more reasons in why the government to bother our family."

"Okay," she nodded.

"Just act natural."

She smiled and walked over to Stan. She meowed at him as she rubbed her body along his lower legs, "Think you're kinda giving overkill Mittens?"

She purred and Stan scratched behind her ears, "Now get out of my house Stan," Lucida stated.

"I'll take this with me then," Stan picked up his briefcase and headed out.

"Good!" Lucida scorned him and slammed the door shut.

"What the hell?" I asked the human, "That could've made me human."

"I know, but trust me on this Bolt. It's better this way."

"How is this better?"

"He'll be back," she smiled weakly.

"Now what should I do?"

"I think you should just..." her voice trailed off when Penny came to us.

"Who was that?" Penny asked.

"Stan," he was wants to buy Bolt," her mother lowered he gaze.

"You said no right?" Penny was getting worried.

"Actually, he made a generous offer," I soon picked up on the fact that Lucida was joking, "He offered thirty million for Bolt."

"You didn't sell him!" Penny was in denial and she was getting very upset.

"You're right, I didn't. I was just pulling your leg."

"Oh c'mon mom!" Penny tried to be mad, but couldn't, "You scared me half to death," Penny dropped to her knees and faced me. She opened her arms for a hug and I happily ran to her. She gave me a hug, "He's my best friend."

"You're mine too penny," I licked her facd and she couldn't help but giggle.

"Now, lets eat shall we?" Lucida chirped.

"Yeah," I said, "Im starving."

My ears pricked up and I wagged my tail so hard that it would fall off. I had a little pep in my step as I followed the redhead and her mother into the kitchen.

We ate quickly and I went to the front door awaiting for Mittens to get the leash. We know I don't need it, but there are laws or something against dogs not having a leash. She got the leash and hooked it onto my collar and she opened the door. I went out first, wanting to hurry up and get to our secret meadow spot. The evening sun caught my eyes and I squinted.

We walked down the pathway in front of us and it soon faded into our driveway. We walked down the driveway and went along the dirt road.

We walked in silence until something drifted in my nose. I slowed to a stop and sniffed the air, "What is it Bolt?" Mittens asked and looked around.

"I smell another dog," I sniffed the air in front of me and soon enough, there was another human jogging. He had a Black Lab on a leash running along side of him.

She was so beautiful as she ran our way. The jogger was forced to slow down when the Lab slowed and came up to me. She panted heavily, "Hey!" she giddily exclaimed, "I'm Max and I've never seen you before!" she spoke fast and her tail wagged faster than he voice.

"I-I-I, uh," I shook my head, "I'm Bolt," I barked at her.

"Well hello there," the man spoke to Mittens.

"Hey, pretty dog," she said.

"I know right," I looked back and barked to her.

"Thanks," Max quickly said, "What kind of dog are you?" she went down on her front paws and I mimicked her pose.

"I'm a Shepard," I fidgeted as she did.

"I'm a Lab!" she licked her maw.

"They seem to be getting along," the guy suggested.

"Yeah," I kept m focus on Max.

"Well, I gotta get going," the guy said, "C'mon Max!" he said and she looked at him with pleading eyes. Not wanting to leave, "It's okay, we'll see them again. We'll see them at the dog park one day."

"We could meet you tomorrow," Mittens suggested.

"How about around three?" he asked, "That's when I'll be home from school."

"Same here. What school do you go to?"

"California High."

"Oh wow! Same here!"

"Is that true?" he smiled, "I'm Jeff," he stretched out his hand for a shake.

"I'm Mittens," she shook his hand and was embarrassed.

"That's a cute name."

"Thank you," she said.

"Then I'll see you at three?"

"Yeah," she smiled.

"Then I'll see you tomorrow at the dog park," e smiled and went back to running. I watched Max pick her pace up to a jog.

"C'mon Bolt," Mittens tugged on my collar and I began walking with her.

We walked for another fifteen minutes before I heard the sound of a river coming up next to us. There were a line of bushes blocking our view from it. Looking around, we saw no one around and went to the bushes. Mittens moved a branch aside and it revealed a path that her and I cleverly made. I went first to make sure that there weren't any spiders because I knew she hated them.

We walked down the path until it revealed an opening of smooth combed over grass. Further down was the river as it slowly made its way left.

"Okay," Mittens began stripping off her shirt and shoes.

"Already?" I cocked y head to the side.

"Yeah, lets go before it gets too late," she kicked off her socks and pants and was left in just panties. Seeing her almost naked got me aroused and ready to fuck.

"Let us get started," she dropped to her knees and took the leash off my collar. I rolled over to my back and she took my six inch cock into her tiny hands. I groaned in pleasure when she began wanking me.

She then took me into her mouth and my tail wagged happily. I felt her bob her head and her warm mouth got smaller and smaller to me as I got bigger and bigger.

When I was fully erect she got off of me with a pop. I looked at her and she wrapped her lips around my tip and swirled her tongue around it. I groaned in response as I felt her tongue rub against my hole. She messages my balls with a hand and sucked harder.

After a few more minutes, she took off her panties moved my hips over my face, "I want you to lick me down there as I suck you off," she growled lustfully.

I didn't say a word and grabbed her hips and stuck my tongue in her wet musky hole. She groaned and silenced herself by sticking my cock back in her mouth.

She smelled so sweet and tasted even better. I stuck my tongue deep in her and she let out a string of muffled moans onto my cock.

What really go me going was when she gripped my cock harder and pumped it hard. I just wanted to cum and was on the verge of it. I would've already but something was stopping me from doing so. In response, I hugged her hips tighter and licked her home deeper as I lightly humped her mouth. She screamed into my cock when my tongue hit the back of her hole.

I felt her pussy then tighten on m tongue and she screamed louder and kept still on my cock. Her juices began to flow onto my mouth as my tongue messaged her harder. She shuddered harder and her pussy clamped tighter around me as she screamed harder. Within seconds, she blasted my face with her sweet juices.

She took her mouth of my cock and yelled my name. Her legs shuddered and her pussy twitched. When she relaxed, she rolled off me and landed on her back.

I rolled over and moved in between her legs. Just when I was just about to mount her and stick her, "Bolt wait," I moved back and and slowly got on her hands and knees facing away from me, "I wanna feel you fuck me from behind," she looked back at me with a smile.

"Find by me," I shrugged and jumped up. I wrapped my paws around her hips again and humped away. I tried to stick her but kept missing and I got more and more upset at the fact I couldn't feel her soft moist walls encompass my member. She gripped my cock and guided it to her entrance. When I felt her suck my tip in I thrusted hard and she yelped, "Not so rough Bolt!" she said and I began slowly thrusting inside her, wanting to savor the moment before I shoved my knot inside her and fill her hard with my seed.

She pushed herself back against me on each thrust and it was heavenly. Her pussy was so much wetter than the last time I fucked it.

I licked her back and she responded by dropping the too half of her body into the grass. Which enabled me to shove another two inches inside of her and greet her cervix, "Oh Fuck! That's It! That's It!" she yelled at the top of her lungs, "Right Fucking There! Oh Shit Bolt! Fuck Me! Fuck Me! Fuck Me! Fuck Me! Fuck Me! Fuck Me!" she yelled on each thrust. Feeling so horny I couldn't help but oblige. I thrusted harder and within seconds, I felt my knot expand quickly. She must've felt it too because she said, "That's it, shove that fucking knot inside of me!" I stopped to force my knot inside of her, "AAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHH!" she screamed when I shoved my knot inside of her. Her pussy tightened around me and she came hard. Juices sprayed everywhere on the base of my stomach, my thighs, and my legs. I waited for a few seconds to allow her pussy to adjust, "Don't Fucking Stop Moving!" she demanded and I began fucking her hard. She moved back and forth because my knot locked us together. I felt my cock thrust inside of her womb repeatedly and was so close to bursting that I needed to release inside of her. So I plowed her into the ground. She dropped her body and I fucked her harder.

"I'm Gonna Cum! I'm Gonna Cum!" I warned her.

"Then Do It! Fill My Womb With Your Lovely Cum!"

It didn't take me long and I came. I blasted her with what felt like I had a fire engine hose as a cock. Unleashing gallons upon gallons of cum inside felt so good. I kept thrusting and I kept cumming. With my forearms wrapped around her, I felt her stomach grow the more I filled her. I couldn't help but get even more turned on and I thrusted as hard as I could inside of her hot orgasming pussy. She screamed a trail of obscenities as I deposited the last of my seed inside of her. When I did, I fell on top of her, "Oh shit that was great," she said hoarsely.

"I know," I snuggled against her back with my knot lodged deeply inside of her, "That was amazing."

"We gotta go when you're knot softens."

"I know, but until then, lets just rest for a bit."

"Fine by me," she stated sleepily.

-Penny-

I made it to my room after dinner and a long shower and dropped into my bed. I thought of what happened earlier when Bolt came into my room when I was pleasing myself. I was thinking of him so much during that time.

I love him you see and I want him to be mine, but our love can't be. He's a dog and I'm human. I know he and Mittens can at least be because she's an animal and it's okay.

I thought about Bolt more and more then soon felt a burning between my legs. 'Ugh', I thought. I knew that ignoring my urges will only make things worse. So I unzipped my pants and stuck my hands between my legs. Heat radiated from my pussy and I just had to cool myself off.

I moved mast my panties and pushed two fingers into my slit and I groaned. I felt such wetness and heat that felt so good to the touch and to be touched.

"Oh Bolt," I whimpered as my fingers brushed up against my sweet spot. I wanted to feel more of my fingers over my sweet spot and I knew I couldn't full reach it without my little 'friend'.

I groaned in distain and pulled off my panties and pants in one swift movement. I soon pulled out a nine inch dildo with a three inch diameter from under my bed. This I got from one of the female teachers I used to date last year.

I laid back and rubbed the tip against my clit and I just moaned in pleasure. I rubbed my breast as I pleased myself and just didn't want it to end, but it had to because I heard the door open and shut. I quickly put away the dildo and put my pants back on.

Within seconds I heard Bolt sniffing outside my door, "Penny?" he said hesitantly, "C-can I come in?"

"Yeah, c'mon on in boy," I sat up and the white Shepard came in. He looked at me with caution and hesitancy, "It's okay, you can come in."

His ears twitched as he walked up to my feet, "Penny, we have to talk."

"About earlier?"

"No, about us," he sat down, "There's something I need to know."

"Anything," I already knew what he was going to ask me and I just want to tell him.

"I love you, do you love me?"

"What about Mittens? Aren't you with her?"

"I thought I was, but she just wants to fuck all the time. Besides, I love you more than her. I want to be with you and I know that because I'm a dog, we won't," his words hung heavily on m heart.

"That's true, but I think I can look past that. You've been my friend for years. Hell, you even came back to me when you were lost," I dropped to m knees in front of him and held his fuzzy face, "I do love you Bolt and I want to be yours."

He smiled and we pressed our foreheads together, "So will you be mine?" he asked.

"Of course," I kissed him and he kissed back. His longish tongue messaged the inside of my mouth and I moaned.
