A very lonely girl tries something new.

Jenni didn’t have much "real" experience, hell, she didn’t even have many friends. She was always the one to prefer spending her evenings alone and cozy in her bedroom, reading her smutty books under her pink girly bedsheets. But night after night of solitude have caused her little kitty to grow impatient. Tonight was one of those nights. She felt herself gently throbbing down there.

It started as a little itch, a slight discomfort. But like a planted seed the discomfort grew, gaining strength by the day. Her hand just isn't cutting it anymore. She lets out a frustrated little huff and checks the calendar. Just as she feared, she was ovulating. “great” she thinks. “Another week of frustration 😒.”

She hated ovulation week. Every cell in her body was screaming at her to find a mate. To find someone to touch her. But what was she supposed to do?? She barely knew any cute boys. Let alone one she could trust enough to sleep with. Hell, even if she did, her parents were right downstairs! She could never manage to sneak a him in here! She let out a frustrated sigh, weighing her options. 

“I guess I could watch porn?” she thought to herself. But just as quickly as the thought had arisen, it had vanished. Between the hormones and the loneliness, Porn just didn’t feel like enough. She felt like she needed contact with a living thing. 

She crossed her arms and pouted, briefly feeling like all hope was lost before the faint tingle of an idea began to materialize in her little head. She remembered one of her friends at a sleepover giggling and talking about phone sex one time. “I wonder if I could find someone to do that with..” she thought to herself. She reached for her phone.

Jenni didn’t really know where to start, so she just took a guess at what to do. She drafted up a post on a shady seeming part of the internet explaining her plight. Her little heart fluttered with surprise and excitement when she saw a glowing red dot appear just moments after pressing send, a notification!

She exchanged pleasantries with the stranger, introducing herself as you would to a new classmate or a relative you’ve never met. She noted that he seemed almost surprised by her joviality, her innocence. Maybe even excited? She thought that was a bit strange, but before she had any time to fester on it her phone rang. It was him. 

“Holy shit, I’m really gonna do this.” She thought. And with shaky hands, she answered.

The opening minutes of the conversation were mostly just her nervous chattering, but his calm presence soon slowed her down. He spoke like he knew everything she was doing. Like he knew her better than she knew herself. And something in him felt.. dark? She wasn’t really sure why, but she felt her pussy start to get a bit warmer, a fact that mildly embarrassed her. She began mindlessly running her fingers over it.

“You’re touching yourself right now. Aren’t you?” He asked.

“Ummm… yeah” she answered sheepishly.

“That’s not enough for a girl like you. Girls like you want more don’t they.” 

Too embarrassed to answer directly, Jenni just managed a quiet “yeah.. I think you’re right.”

“So awful that a girl like you is trapped all alone in your room touching yourself. I bet your parents are just outside the door. Poor Jenni gets so horny she doesn’t know what to do with herself.”

She felt herself getting more excited by the minute. There was a certain thrill to feeling exposed. 

“no… I don’t think… umm it’s not enough, you’re right. I… I want more.” She admitted. 

“I thought so. You need to feel warmth, you need to feel what it’s like to be mated. It’s cruel for a little one like you to be all alone. I can make that happen, but you’re going to have to do everything I say, do you understand?” He stated.

She felt herself hesitate. This felt like a point of no return. She had no idea what this stranger had in store for her, but somehow she knew if she agreed, she would do it. There would be no going back. She felt her herself throbbing. 

“I… I think… okay I’ll do it.” It came out almost as a whisper.

“Good girl.” He said. He sounded like he was grinning on the other end of the line. “Do you have a dog?” 

She wrinkled her brow in confusion, but she answered honestly. “Ummm yeah, a german Shepherd. he's right here on my bedroom floor." She replied. Wondering what on earth the relevance could be.

"Good. Take off your clothes, Get on the floor, crawl over to your dog. What is his name?”

Looking back on it, she couldn’t believe how naive she was. Even as she obliged him, she still didn’t *really* know what was happening, she just sort of… did it. She slipped off her clothes and crawled over to her lounging pet. “His name is Russ.” She said.

“I know you’ve never touched a cock before. I know you’ve dreamed about it.. Reach out and feel Reel Russ’s. Tell me what it feels like.”

“WHAT?! You want me to touch my dogs penis???” She nearly shouted.

“Careful now… your parents are just outside the door. Don’t make me warn you again.” He said in a menacing tone.

“Oh umm yeah I’m sorry I was just.. uhh I was just surprised it all. Do I really need to touch it?” She said apologetically.

“Yes you do. Go ahead and hold it, rub it back and forth. What does it feel like?”

Jenni reached out timidly and grasped Russ’s sheathed cock. It felt incredibly warm to the touch. She began stroking it back and forth, Russ’s ears perked.

“It feels warm.” She replied, nearly giggling at the hilarity of the situation. Was she really touching her dogs penis?? This had to be a dream.

“Good girl. Now do you see a red tip poking out?” He asked.

“Oh umm yeah, I see a red thing poking out. What is that??” She asked.

“That’s Russ’s cock. It means you’re doing a very good job! While you stroke him, go ahead and put your mouth over it, play with it with your tongue.”

Jenni felt herself hesitate again. “Umm it looks kinda shiny and wet and… idk should I really be doing thi…”

He cut her off mid sentence. “Do as you’re told little one.”

She paused, fear gripped her for a few seconds.  

“…okay”.  

She bent down and began playing with it, using her tongue to swirl around his tip while she stroked him. It tasted surprisingly.. okay? She wouldn’t say good but, but not as bad as she would have thought. She felt the red part growing, protruding more and more.

“Umm he’s getting a lot bigger, is that okay?” She asked.

“Yes, it means you were a very good girl and Russ is getting ready to play with you! Now you get to do the fun part… Get onto your hands and knees and crawl up in front of big Russ. Give him a little show and wiggle your bum for him. He’ll probably be very excited to see it.”

Jenni did as she was told. She was very nervous about where this was going, but she honestly couldn’t stop herself anymore. Some mix of loneliness and raging hormones had driven her over the edge, she was just so unbelievably horny. She almost didn’t recognize herself at this point. Like, who even was this girl who just licked her dogs penis? What was happening to her!? 

Before she even had a moment to think, she felt a wet nose sniffing aggressively at her kitty, followed by a lick so firm it felt like he was trying to taste her from the inside out. The feeling nearly made her jump.

“Umm mister he’s licking me, is that normal.” She asked nervously.

“Yes, he’s just making sure you’re ready for him. He can smell when little girls are excited. Just be patient. You’re doing good.” 

“Okay.. umm hmm he’s…” and before she could finish her sentence she felt his entire weight crawl up onto her back, his paws scratching at her sides as they impatiently got into a mounting position. She felt something wet and hard poking randomly at her lower half. Russ was wildly humping.

Within a split second he found his mark and plunged into her pussy, causing her to squeak in surprise and stinging pain as he plunged deep inside of her and began thrusting uncontrollably. Russ was an animal, he didn’t know how to wait, he was ready.

“Bite your hand, and don’t make a peep.” The man warned over the phone. “If your parents hear you they’ll take poor Russ away.  Be.. quiet.”

She bit her hand and braced herself as Russ thrusted, her cheek now rubbing on the ground as he rocked her whole body.

“You’re doing such good job. Just relax and it’ll start to feel good. Trust me, every little girl’s first time with their doggie stings at first” the man reassured.

She only managed a muffled grunt in response, too busy biting her hand to make any noise, but she noticed a change happening. Slowly at first, then more and more. It felt… good. Like, really good. Her muffled grunts turned into soft moans, then real, proper moans. She didn’t dare to take her hand out of her mouth.

The man laughed as he heard the change in her noises.

“I can tell you’re enjoying him now. Here’s what you’re going to do. When you feel him start to slow down and get bigger, you’re going to push your bum back into him and get him as deeeep as you can. Then you’re going to take your other hand and rub your pussy. That will help you feel good while Russ grows his knot inside of you, do you understand?”

“mhm” Jenni managed to humm out in between her stifled moans. 

And sure enough, he was right. She felt a swelling, full sensation. She took her other hand and quickly began rubbing her pussy. Russ’s pounding had abruptly stopped, and he pressed himself into her. She did as she was told and pushed herself back into him, feeling him sink deeper into her than she’d ever felt anything before. Feeling him tickle the very deepest parts of her kitty. Parts that nothing had ever touched before. 

“How.. mmm how big is he.. uhhh.. ahhh.. going to get.” She managed to squeak out. 

“Just keep rubbing. You’ll like this part.” He replied.

Jenni did as she was told, and sure enough she felt something start to build. She was so full of Russ she thought she was going to burst. It felt like there was electricity coming from her pussy. The size, it felt.. indescribable. Was this really what sex felt like?? She could have never imagined it could be this nice.

She rubbed harder and harder. Feeling herself full of Russ, feeling his warm furr press into her back, feeling his hot breath above her head. It felt like heaven, like the best thing she’d ever done. She was so close.. she was gonna…

Jenni bit her hand as hard as she could but the orgasm was just too strong. She nearly screamed with pleasure before falling limp. Her hand dropping from her clit onto the ground in between her legs. She laid there in a daze, drooling gently onto the ground. She was half way between awake and asleep, her mind completely empty of every thought.

After a few moments of rest she came back down to earth. She looked back at Russ, who was now trying to get off of her. She was still stuck. Russ’s knot hadn’t gone down hardly at all and she could feel it holding him to her. 

“Um mister that was amazing but he’s still stuck. Is that normal?” She asked, still basking in the afterglow of her first time having sex.

“Oh yes, it means you did such a good job of making Russ happy. He’s taking extra care to put cum in you. Just slowly and gently lower your hips and he’ll pop out.”

“Oh.. okay I’ll try that I guess.” She replied. And began slowly working him out, pulling away from him. Just as she felt him start to move he popped out all at once, the stinging jolt causing her to squeal loudly. She felt warm liquids gushing out of her onto the ground, onto her legs. There was so much it felt like she peed herself.

“Oh crap. I’m sorry mister that was loud” and sure enough just moments later she heard her mother climbing the stairs.

“Jenni sweetie? Everything alright? It sounded like you yelled.” Her mom asked from down the hall, approaching steadily.

Jenni looked at the ground. There was an enormous puddle that came from her. Russ had made quite a mess. Operating on pure instinct she grabbed her clothes and threw them on top of the wet sticky spot. She grabbed her phone and dove under the covers, getting in bed not a single second before her mom opened the door.

“Oh yeah haha, sorry mom that was me. I just had a bad dream.” She said nervously.

“Alright dear, just making sure.” Her mom said warmly, before turning and closing the door.

“Holy crap that was a close one!” Jenny whispered into her phone.

“It was.. you’ll get better at that part with practice. You did very good tonight little one.” He calmly replied.

“Hey ummm mister. thank you… I think that was the best night of my entire life.” She said, already drifting off to sleep as her adrenaline wore off.

“I know it was little one.” And the phone went silent.

A good girl's first time dogsitting.

I felt my perfect weekend slipping away from me while my Jenni enthusiastically jumped up and said “don’t worry! We can watch him!” 

Her selflessness was one of the things I loved about her, but in times like right now, I wish she could dial it back a bit. Our friends looked relieved.

“You guys are lifesavers!” they exclaimed. “Our dog sitter backed out last minute and we were totally panicking. We were planning on leaving tomorrow at 8am.”

We began working out the details. They only had one dog, a German shepherd named Rex. This shouldn’t be too bad. Besides, they offered to let us stay in their house for the weekend. It would be a little “staycation” I told myself.

We got there early the next day and did the handoff, our friends took off for their camping trip and we spent the rest of the day just hanging out and getting acquainted with Rex. Jenni loved him, and right away I noticed he loved her.

As the sun went down we decided to make use of their hot tub. “Shit”, I muttered while looking at the stuff we packed. “We didn’t bring any bathing suits.”  

“Oh that’s no big deal, I’ll go look for theirs and if I can’t find any we’ll just skinny dip” Jenni replied with a little grin before walking into the master bedroom. She wasn’t usually this playful, something had gotten her a little excited. I could always tell, I’d known her for years.

Not even 5 seconds later i heard her gleefully shout “omg MARK! Come look at this hahaha!” She had made her way into one of their closet drawers on her hunt for a bikini, and found a treasure trove of their sex toys. And I mean a TREASURE TROVE! 

They had everything you could think of, vibrators, restraints, dildos. I raised my eyebrow as Jenni picked up one in particular, it was bright red and had a funny shape. “Whats this one supposed to be?” She asked with a childish smile. 

“It’s shaped like a dog, that right there is the knot.” I replied.  

Jenni looked shocked for a second then giggled. “Are they really that big?! This thing is huge!! I can’t even get my fingers around the knot thingy!!” She tried to grip it, her hands looking smaller than ever handling the massive toy.

“They can be, I saw my old dog mating once years ago. He was about that size.” I replied. Jenni raised her eyebrow, smiled again, and put the toy back. My heart was starting to pound faster. She was not normally this curious. She was horny, I could feel it. 

“Well, looks like we have a lot of stuff to try out after we get out of the tub.” And with that, she smiled and slipped out of all of her clothes before walking out of the room naked. “I changed my mind, skinny dipping sounds fun.” She yelled back to me while walking down the hallway. I stripped down and followed after her.

The hot tub was more or less uneventful, after an hour of us fooling around she jumped out and dried off, I followed her into the house, then into the master bedroom where she seductively told me to go pick out whatever I wanted before hopping onto their bed. I had already been planning what to use from their drawer. I flashed her a dark smile and went to get the toys.

I came back with a vibrator, the dog dildo, a blindfold, and some restraints. Her eyes went wide when they locked onto the massive doggie dildo, her confident smile turned to a look of slight concern and intrigue. But one thing she didn’t do, she didn’t protest. 

“Are.. are you gonna use that one on me?” She asked.

“Yes.” I replied calmly.

Her look of nervous intrigue intensified. “Where do you want me?” She asked.  

I silently motioned to the carpeted floor.

She got down on her hands and knees and patiently waited while I got her ready. First blindfolding her, then pressing her face into the ground and tying her hands to her ankles. Her cheekiness had all but evaporated. She was now almost shaking from being so exposed, her face to the floor, her hands tied, her ass up in the air. I could almost smell her arousal. Her breathing was heavy.

I started with the vibrator, she almost jumped when it touched her clit. The arousal and anticipation had made her sensitive. For minutes on end I worked her closer and closer to an orgasm, listening to her desperate moans, only to pull away each time at the crucial moment. She started pushing backwards into it, or at least trying to while in her restrained state. Her body language begging me to keep it there just a bit longer. But I had plans for her.

She was on display for the whole room to see, and she was visibly glistening. The room was almost heavy with the smell of her sex while I reached over to grab the doggie dildo and start the next step of my plan. But as I leaned, I noticed something walk past me out of the corner to my eye. Rex must have also smelled her, and before I could react he started lapping at her restrained and exposed pussy.

I was just moments from yanking him away, when she let out a deep moan. 

“Mmmm.. Wha… what the fuck are you doing back there??” She gasped

Rex began to plunge his tongue even deeper into her, greedily lapping up every drop of her that he could get. The noises she made only intensified, I couldn’t believe what I was seeing, she… she was actually starting to like this.

I watched, stunned, as her pleasure built higher and higher. Her face writhing and moaning into the carpet as Rex’s powerful tongue pushed her ever closer to an orgasm. She MUST have figured out what was going on by now, but it didn’t matter, she was lost in the sensation. The teasing had left her so pathetically desperate to finish that she didn’t give a fuck what would get her there any more, she just needed to cum.

And soon she gasped, moaned, almost yelled, while he pushed her over the edge. Her body trembled while she breathlessly repeated “oh fuck, oh fuck, good boy! yes! Fuck! good boy!”

I had never been so turned on in my life. The good girl, the bubbly one, my innocent little Jenni had just cum so hard into the mouth of a literal animal that she was unresponsive on the floor, drunk with hormones and pleasure. I’d never seen someone so content, so exposed, so helpless.  

I turned to look at Rex, and I noticed something, he was hard. His glistening cock, poking out of his sheath. He was already gently dripping with cum. I could tell he was huge, and he wanted more.

I turned back to Jenni. She was still breathing softly, hands and feet bound together, face on the ground, half asleep, blindfolded. A wicked thought began to build within my mind. She… she was tied, and half asleep. She couldn’t protest, I could do whatever I wanted, I could let REX do whatever he wanted..

Almost on autopilot, I reached out and grabbed Rex by the cock, it was warmer and thicker than anything I’d ever felt. And I began pulling him forward, towards her.  He took one click glance back at me, and he began to mount her.

The moment his weight was on her, and his front paws were scratching her shoulders she snapped out of her daze. She began to squirm and shouted “MARK! What the fuck is he doin….” And with that she was interrupted. His cock had found her entrance and in a split second he had begun fucking her with the ferocity only an animal could posses.

“fuck fuck fuck! he’s big!” She screamed. He was pounding all 9 inches of himself into her harder than any human could ever dream of. He didn’t care if it felt good or not for her, he didn’t care if she came, he was an animal and he wanted one thing and one thing only, to breed.

“Fuck! Oh my god! Aghhh! Shit! Please! Cum in me! Please!” She screamed in between grunts of pain and moans of pleasure. I had never heard her so vocal, so vulgar. This was a side I hadn’t seen before, she had given herself to him, she had surrendered to his violent thrusting. She was his, and she was loving it.

His thrusting soon began to slow, and he pressed in one last time before holding. I couldn’t believe my eyes, he was knotting her. Her shouts and grunt turned into gentle moans, building up and she felt the pressure of all 9 inches of him and his massive knot begin to swell, to fill her. She was trapped and she was being forcefully filled with his doggie cum.

I reached under both of them and began rubbing her clit, causing her moans to start building again. I could feel the tightness of the skin as I rubbed, he must have been enormous in there, the size of a baseball at least. Stretching her, tying her to him. Keeping her captive while he pumped her completely full. No wonder she was getting close again. 

Pretty soon she was right on the edge. His cum had filled her completely, he was pressing into her cervix, trying to put his puppies in her, and she was loving the sensation. 

She let out a gasp, and came HARD. The uncontrollable spasms in her pussy pushing out his baseball sized knot with a violent pop. while she screamed with a mix of pain and pleasure, she began shaking. More cum than I’d ever seen in my entire life gushed out of her and down her legs, into a puddle on the floor. More than any human could ever dream of putting into her. His sheer size had left her pussy gaping, red, and swollen. His white puddle resting deep inside of her, gently dripping out from time to time. She had passed out.

While I untried her hands and feet I thought about how she was going to be sore for a week. A gentle reminded of what she did, and how much she liked it. I picked up her sleeping body and placed her gently down on the bed. 

My sweet innocent Jenni had just fucked our friend’s dog, and something told me she had loved it more than anything she’s ever done in her entire life.

[M4F] You're ovulating all alone in your room again, nearly losing your mind to horniness. In your vulnerable state, a Dark online stranger talks you into doing something that you never imagined yourself doing. You'll never look at yourself or your pet the same again, but god did it feel good.

I am 18+ and all participants and character must be 18+

You don't have much "real" experience, hell, you don't even have many friends. You prefer to spend your evenings alone and cozy in your bedroom reading your smutty books under your pink girly bedsheets. But night after night of solitude have caused your little kitty to grow impatient. Every night she throbs, practically begging you to find her some company. Your hand just isn't cutting it for her anymore, she wants to be treated like the girls she sees on the screen, she wants to be used. And you secretly want that for her too.

But what are you supposed to do?? you don't know any boys! and even if you did your parents are right downstairs, you could never manage to sneak one in here! You let out a frustrated sigh. "I guess it'll be another night of phone sex with strangers and rubbing myself alone", you think to yourself. But as you find your partner online and get your nightly routine started, something feels... different... As he begins to speak, you realize that the stranger you've met tonight is a bit darker... You feel a wave nervous excitement wash over you as you hang on his words.

"Do you have a dog?" he asks.

"Ummm yeah, a german Shepherd. he's right here on my bedroom floor." You reply, wondering what on earth the relevance of this could be.

"Would you do anything to feel what its like to be bred tonight?" He asks, matter of factly.

You gulp, you don't know where this is going but something about him makes you feel like you cant lie, like he'll know. so you answer truthfully, so quiet it almost comes out as a whisper. "...yes"

"Good girl. Im going to make that happen for you, but you're going to need to do exactly as I say. Now get off your bed and get onto the floor."

To be continued...

Looking for a more long term thing to build a trusting relationship and explore.

Keeping her captive while he pumped her completely full. No wonder she was getting close again. 

Pretty soon she was right on the edge. His cum had filled her completely, he was pressing into her cervix, trying to put his puppies in her, and she was loving the sensation. 

She let out a gasp, and came HARD. The uncontrollable spasms in her pussy pushing out his baseball sized knot with a violent pop. while she screamed with a mix of pain and pleasure, she began shaking. More cum than I’d ever seen in my entire life gushed out of her and down her legs, into a puddle on the floor. More than any human could ever dream of putting into her. His sheer size had left her pussy gaping, red, and swollen. His white puddle resting deep inside of her, gently dripping out from time to time. She had passed out.

While I untried her hands and feet I thought about how she was going to be sore for a week. A gentle reminded of what she did, and how much she liked it. I picked up her sleeping body and placed her gently down on the bed. 

My sweet innocent Jenni had just fucked our friend’s dog, and something told me she had loved it more than anything she’s ever done in her entire life.
