"Shut up, Sev! Where the fuck are those keys? God i'm late !" Erica growled, to her four year old rottweiler who was barking wildly.
The girl quickly straightened her school uniform, ignoring the dog's insistent barks as she passed the living room.
Erica couldn't find her keys anywhere, and growled angrily, gritting her teeth and rolling her eyes as Severus watched her intently.
Erica looked at him arching an eyebrow " Well…? What are you looking at ? Do you know where they are?" she asked trying to reign her irritation.
That day was one of her worst 'No days' .
Severus tilted his head whining with an innocent expression, and Erica's eyes landed between the dog's legs where she could see the tip of his red penis poking out of his sheath.
Erica blushed furiously, involuntarily staring between her dog's legs and feeling her loins tingle.
She shook herself and returned to her search for the keys, while Severus trotted behind her.
The Rottweiler seemed very excited lately and Erica didn't know what to do to calm him down.
"Severus, sit!" she commanded flashing him a glare and the Rottweiler sat, his tail wagging furiously as his intense eyes followed his owner every move.
As she turned to keep searching for those damned keys, Severus suddenly jumped, taking her by surprise.
Erica yelped and went crashing to the floor, hitting the wood with a painful thump.
"Ow, Severus! Bad dog! If i'll be late for school, it will be your fault ! "
She was really furious this time.
The dog just stood there, tail wagging and tongue lolling.
Erica growled, and turned onto her hands and knees to get up.
She was about to stand when she felt a powerful pressure between her legs.
She looked back, and Severus was behind her, his head bobbing as he licked her cloth-covered pussy.
Erica was in shock, watching as the rottweiler licked her, every probing thrust of his tongue pressed up against her panties, but the thin cloth did little to dull the sensations she felt throbbing through her swollen vulva.
As if suddenly realizing what was going on, the girl said, "No, Severus! Bad!" but the dog didn't relent.
Embarrassed, Erica pushed his face away.
Severus stopped, but only for a second before he knelt beneath her, forcing his muzzle to continue his dedicated licks.
Erica readjusted her weight to her legs, trying to ignore Severus's unrelenting tongue, and started to stand.
Riiiiiiip! Severus had clenched his teeth around the thin cloth that covered her genitals, and pulled back, shredding them.
Erica's jaw dropped, looking at the Rottweiler with the tattered remains of her panties in his mouth.
Erica watched in horror as the dog spit the cloth onto the floor and pushed his snout up under her school skirt.
Erica's eyes widened and she yelped as she felt Severus's tongue directly against her moist pussy. The warm, wet organ sent electricity coursing through her body, and she couldn't keep her awkward position. She collapsed back to all fours, biting her lip as Severus began slathering her pussy.
This was obscene!
Erica couldn't understand what she was doing.
The dog ignored her commands.
She was a girl, not a bitch!
Erica stood, or she tried to.
Severus suddenly growled and nipped her rump.
She let out a high-pitched whine and stayed put, her backside still stinging.
Erica trembled in sudden fear as Severus resumed licking her.
She was crouched, her butt raised to give Severus full access to her pussy.
The dog's tongue ran along the length of her slit, becoming more forceful every second, until finally he forced his way between her lips.
Erica whimpered helplessly, as she tried to ignore his probing licks.
Severus's growl and bite hadn't really been aggressive, more like he was asserting his dominance.
Erica didn't know if he would escalate if she continued to defy him.
But she decided, she had to try.
She ended to go to school, and she was already late!
The girl turned away from the dog, her butt feeling strangely empty without his tongue.
Then she saw something that made her heart skip a beat.
A dark shape clouded the translucent glass beside the front door.
One of her classmates was trying to look in!
Thank god the glass obscured everything but dim shadows.
"Erica? You in there?"
Should she call out for help?
Erica wasn't sure she could ever live this down, but maybe it was more important that she get out of this situation than retain her pride.
She gasped, muffling her yelp when she realized that Severus had jumped her.
He rested his bulk on her butt, his forepaws locking around her hips.
She looked back, her eyes fixed on his erection, which had grown considerably, his knot had already swollen even if not so much.
"Erica? I'm coming in!"
She turned back to the front door, petrified.
Her friend would immediately see them, and her life would be over.
Had her father locked the door?
He never remembers to lock the door!
She knew she should do something, but she was speechless.
Click-clunk!
The door was locked! She was saved. Her father must have locked it .
Squelch!
Erica's eyes widened.
A cold chill filled her gut, as she felt something large and firm rocket between her legs.
Her classmate still stood at the front door, so Erica summoned all of her willpower not to scream.
The shadow moved away, guessing that she wasn't home.
The girl knew exactly what had happened, but she refused to believe it until she looked back.
Sure enough, Severus had thrust, and her sopping vulva had parted as easily as a cheap whore's legs. Now the dog waggled his hips back and forth, driving his cock into the young girl.
She felt his small knot pressuring her entrance.
Fearing her classmate might still hear her, the girl forced herself to remain quiet, silently screaming.
Erica held her ass hight, and had to use all her willpower just to stop thrusting her hips.
Shuddering, she whispered, "No, Severus...no..." but all the strength in her voice was gone.
She had to get out of there!
She tried to stand, but the Rottweiler was heavy, and his grip was strong.
Every time she made any ground, his next thrust pushed her back to her hands and knees.
Erica turned around and tried to push him off of her, but he growled.
The girl was beginning to realize that she was helpless to stop him.
She suddenly felt very alone.
Her parents were doing a trip to the sea and would be gone for the weekend.
She prayed her classmates hadn't already left. "Guuuuyyyssss! Help me!" she screamed.
No answer. She tried again, "Please, help me!" No, she was too late.
No one would hear her; no one could save her.
Erica sank in despair as Severus continued to pound her pussy.
He grunted as he thrust harder and harder, forcing his knot against her violated vulva.
Erica no longer had the willpower to stop herself from thrusting back.
Whimpering, she tensed her muscles, her vulva beginning to stretch painfully in its attempts to take his knot.
Erica moaned and laid her head on the ground in despair.
Opening her eyes, she looked beyond her tight blouse.
Her skirt was bunched up against her body, allowing her to watch.
She groaned as she focused on Severus glistening cock repeatedly penetrating her, his hefty balls swinging like a pendulum behind her.
It seemed like a life-time ago that she had been preparing for the last day of school of the week.
Now she was on her hands and knees, getting fucked by her dog.
Severus rammed his cock all the way into her, his knot beginning to stretch her vulva.
Erica's nether lips spread almost eagerly for him, her insides clenching around him, pulling him in.
Thrust! Erica slid her right arm out of the navy jacket. Thrust! She removed her left arm, moaning as she felt Severus's knot trying to spread her almost all the way.
Thrust! Erica wrapped her fingers before the knot, managing to to stop it from entering her.
Severus's erection just kept moving forward, the massive glands at the base of his cock spreading her apart even further.
Pop! Severus howled triumphantly.
The girl's hand felt his knot.
Amazingly, she discovered that Severus was only halfway in!
Severus pulled out of her, before he rammed back in.
Erica looked back, watching the almost hypnotic swaying of the Rottweiler's hips, a blur of brown and black, her pale skin intermingling with his fur where they met.
Erica's ears caught the sounds, wet slurps and splashes in the background behind Severus's rapid grunts.
But the loudest sound was her own panting moans. Severus smelled incredible, his masculine musk lingering in the air, the aroma blanketing the room and everything in it.
But the most noticeable sensation was feel.
Erica felt his tugging pressure on her hips, his weight on her back.
She felt his fur rubbing against her skin, creating a warm friction along her back and rump.
Her breasts were being pressed painfully against her as Severus pulled on her blouse, and with one more powerful thrust, the back ripped out, and her blouse fell uselessly to the ground beneath her.
Erica still wore shoes and her skirt, but her breasts hung loose below her, swaying back and forth.
Then she felt Severus's teeth on the nape of her neck. He pulled, and she had no choice but to lift her head, moaning into the air.
Above all, Erica felt his rock hard cock frantically flying between her wet folds.
She didn't know how it had taking her so long to fixate on that feeling.
She held her head high, whimpering helplessly into the air.
She arched her back and spread her legs, holding her ass as hight as she could.
Each time Severus cock cleaved her enlarged pussy, she pushed back, thrusting her own hips like a rutting bitch.
But Erica would never submit to a mere animal.
She was too strong for that.
Yet there she was, whimpering and moaning, meeting thrust with thrust.
Splortch-splortch-splortch-splortch!
Again and again Severus fleshy organ pressed past the source of her lust.
She wasn't sure she had ever felt as hot as right then. She wanted to lower her hand and take his entire knot but .
Erica wanted to thrust against the dog until he released powerfully inside of her.
Looking down between her legs, Erica could see herself dripping all over the floor, and she could see a few drops of milky white fluid.
She blushed, thinking with relief that if Severus came inside her she couldn't get pregnant, she wasn't a bitch, so she might as well enjoy it!
With sudden, surprising dedication, Erica began to shiver and moan, rolling her hips in a tantalizing circle and brushing her clitoris with her hand.
Severus began to whimper as well, and the girl knew he was nearing his inevitable climax.
He was so ferocious, so bestial, so dominating.
Erica moaned, so close to her own orgasm that she could feel it.
Erica had truly and completely submitted to the dog
she was his, in mind, body, and spirit.
"Fuck me, Severus!" she yelped, her profanity seeming to pale in comparison to the fact that she was fucked by a dog.
Her body went crazy as the most powerful orgasm of her life overwhelmed her.
Her insides clenched and gushed, and her entire body quivered violently.
Her moans echoed throughout the otherwise quiet house, and she began flinging her hips up and down with reckless abandon.
Severus held on for dear life, his howl joining her moans.
Her ears could hear the loud splashes of Severus's ejaculations as he made her his bitch in every conceivable way.
Erica just moaned and whimpered, Severus cock had slipped out of her spewing rivers of cum on the floor.
If Erica hadn't given herself fully over to the Rottweiler's whims, she never would have experienced such a mind-blowing orgasm.
When Severus was finished he hopped off of her, as she turned over and slumped down in exhaustion, oblivious to the pool of semen she had just lay in.
"Oh my god!" Severus spun around and laid down a few feet away, watching her with a curious look.
"Oh my god," Erica repeated.
Severus had just fucked her, and Erica had liked it! What would her parents think of her if they knew? Erica sighed and stood, her legs sore, her shoes and skirt were soaked, her jacket ripped, and her blouse in ruins.
She kicked off her shoes and socks, and slid her skirt off. then she took her phone and send a quick message to her classmate's phone telling him she wasn't feeling all right and that she would be seeing them on Monday.
Erica put the phone on the table and laid back on the floor.
She heard the jingle of Severus's collar and she looked over at him.
Severus stood, and approached her, sniffing.
"What do you want now?" she asked him but without anger, almost expecting him to answer.
Severus sniffed at Erica's wet entrance, and to her surprise, he stuck out his tongue, lathering her again.
"Hey!" she exclaimed, she couldn't cover herself before the dog rammed his tongue deep inside of her once more.
Erica arched her back and moaned, not ready for such attentions so soon.
The warm tongue soothed her sore vagina, and against her better judgment, she kept her hands at her sides.
The naked, girl laid back and let the dog taste her. Slurp! "Unf! Well, maybe you'll get some of your cum while you're in there," she laughed.
Severus licks didn't slow down, driving his tongue repeatedly between her tender lips.
Erica couldn't handle the sensation, so she put her hands on Severus's head, guiding him.
His tongue felt incredibly soothing against the girl's swollen genitals.
Erica had already felt Severus's cock inside of her, what did it matter if she enjoyed his tongue.
Erica guided him deeper.
She wanted to call out encouraging words to the dog, but all that came out were whimpers.
Erica began thrusting her hips against him, trying to draw his tongue as far between her legs as possible. She thought to herself, "Oh god, what am I doing? This is so wrong..."
But she didn't stop, whining for more.
She lay back in pleasure until finally, Severus pulled away from her.
She smiled, and Severus just looked at her expectantly.
He looked excited, and barked at her, nudging her with his snout.
Erica looked down and saw that he was 'excited' in more ways than one.
She knew what he wanted now, because she wanted it too, she realized.
With a smile she flipped over onto her hands and knees and stood in front of him.
The girl looked over her shoulder at the horny dog, as she lifted her butt and presented herself like a bitch ready to be bred, in all her naked glory.
"Ready for round two boy? What are you waiting for then… Breed me, make me your bitch once and for all Sev !" she moaned.
Severus barked in excitement and approached her from behind, sniffing her presented butt.
Erica shivered but stayed put as he gave her a tentative lick.
Erica gasped, she had been a human, a student, a teenager, but now she was nothing but a bitch in heat. With a helpless whimper, she spread her legs for her alpha, and he found his mark.
She yelped, feeling the massive organ glide effortlessly into her swollen pussy.
This time, Severus didn't grip her neck with his teeth and she immediately began to swing her hips, while Severus pulled himself further on top of the girl.
Erica felt so good to be his.
Severus was a huge and generous mate, his cock quenched the burning that permeated her passageway, causing her to moan.
Erica could feel his knot swelling, just outside of her. She pushed back, trying to get it inside of her, it was already too big to enter her easily.
Her mate pulled forcefully on her hips with each thrust, ramming his knot against her stretching vulva. Severus was in control, and she knew it.
Her life was his, her pussy was his. In moments, her womb would be his too. " you know, boy that i can't get pregnant with your seed ?" she asked playfully, but moaned when the dog began to thrust more faster.
Severus pounded his willing, obedient bitch, lifting her off the ground with each thrust as he tried to force his full-sized knot between her spread and welcoming legs.
Erica arched her back and moaned, desperate to feel him entirely inside of her.
She looked back to watch Severus as he worked, grinding his hips against hers, and gave him an affectionate kiss on the face.
Every second, her entire body thrilled to feel his thrusting knot spreading her apart just a little further. Erica pushed back with all her strength, whining as her vulva stretched painfully.
Squelch! Her wet folds offered little resistance as his shaft plumbed her depths.
Erica's vulva spread further and further as he pushed each new inch of length between her lips.
And then his knot collided with her taut lips, but it didn't stop there.
The swollen knot kept forward, forcing her vulva to stretch beyond any imagination, when he had fucked her a few minutes prior his knot wasn't that big, she realized, as she yelped at the sudden pain of his entry.
She was spread several inches apart, but his knot was still too big, and then the rotweiler hopped forward, pushing Erica down with the strength of his thrust.
Squelch! Her vulva slid closed around him.
The only thing that went through Erica's mind was unmitigated, unimaginable pleasure.
Severus tip was brushing up against her cervix.
Every centimeter inside of her was occupied by his red, glistening cock, and his incredible girth was positioned perfectly to pressure her clitoris.
Erica was in bliss.
She moaned as Severus continued to thrust.
He was only able to move an inch back and forth. His massive balls swung, slapping against her inner thighs.
Severus had tackled her, courted her, mounted her, and now was going to make her his bitch.
Just below her, she saw the pool of semen that had comprised Severus's last ejaculation.
Erica couldn't speak, finding her yelps, moans and whines more natural now.
So, instead of chanting "Yes!" with each thrust, she just whimpered.
Severus drilled the girl, a low howl emerging from his throat.
As the pitch rose, the noise drowned out everything for Erica other than the intense pleasure that wracked her body.
Over and over, his tip stabbed against her cervix, as if seeking a more direct entrance, and her vagina clenched around him, as if trying to grant him that. Erica panted wildly, drooling onto the floor.
Severus pushed against her, hard, and she heard something that made her eyes widen.
Splurt! That was it.
She could smell his fresh semen as he fired inside of her.
Splurt! She could hear it splashing forcefully against her cervical walls.
Splurt! She could feel the pressure inside of her building, as the river flowing inside of her bulged in her vulva.
She could feel the flood of dog seed as it breached her cervix, rushing into her womb. Her last ounce of humanity was gone.
Erica's scream of pleasure joined his howl, and she went crazy, thrusting her hips and clenching around him.
Her vaginal walls milked the giant cock for all it was worth, eagerly pulling his seed into her womb.
Every three or four seconds, Severus would hump, firing another load inside of her, and she would moan happily.
The odors were intoxicating as she shuddered underneath her alpha.
Severus was panting and groaning, until finally he stopped.
Erica didn't mind, though.
She had served her purpose.
She was his bitch now, his and no one else's.
The rottweiler stepped over her until they were rump to rump, as was customary for dogs.
This put small pressure on the massive bulge that still locked them together, in time he would shrink, and they would separate, physically.
But Erica knew they were together at a much deeper level.
They were mates now.
After a few minutes the knot exited from her
and the girl collapsed on the clean floor, her tongue lolling out as she panted, Severus approached her, and she smiled softly, until he stood face to face with Erica, looking in her eyes "good boy, Sevrus…" she slurred and sighed blissfully, looking up at him.
He almost seemed worried about her.
Erica raised her head to touch noses with Severus, and kissed him.
Her arousal grew once more, and the scent flared in Severus's nostrils.
Erica snuck a hand between his legs and cupped his growing cock " You know what we humans say, Boy? Three time 's the charm."
Severus barked happily as he prepared to mount his bitch again.
Hiding his owner's keys had been a great idea!
