Cindy headed into her bathroom, pulling the door closed most of the way behind her and began to undress. She’d been working out in her garden in the backyard all day so she was pretty dirty and sweaty and she needed a bath. It was a really small bathroom so she never shut the door all the way. It got much too muggy in the bathroom with the steam from the hot water or shower when she did that.

 

She always had the bad habit of leaving the back patio door open when she came back in or went out too. She had a huge backyard fence, though, so no one could really get in. It was safe and that way her dog, Thunder, could have the run of the house and the yard both.

 

She hadn’t always had a dog. She’d actually inherited him from her elderly neighbor when she passed away. It was in her will with a note for her that said “I hope he is as good for you on those lonely nights as he has been for me.”

 

And he had been. His companionship had been a wonderful change to her solitary days at home. She worked from home so she didn’t get out very much.

 

As Cindy stripped her clothing off, she imagined herself dancing in a bar for a dozen horny guys. She rubbed her hands over her breasts, taunting the imaginary men watching her. After she took her shirt off she ran her hands down inside her cut off sweats fingering her cunt and licking her lips lewdly. Her eyes were shut tight and she swayed her hips back and forth as she touched herself never knowing she was really being watched.

 

Finally she pulled her shorts off, reveling the fact that she had no underwear beneath them and she imagined one man calling out. She got hotter as she heard him calling her a dirty slut. She dipped a second finger in her pussy, working it deep inside herself and rubbing it over her clit as her shorts fell to the floor.

 

After she stepped out of them she leaned over the tub to stopper it and turn the water for her bath and she felt something that wasn’t herself down at her privates. It happened so fast, she wasn’t sure what it was and there it was again. It felt like a tongue only a bit different.

 

She pulled away from whatever it was but she slipped on the rug and went crashing down onto the side of the tub, the wind knocked out of her. As she recovered, gasping for breath she was in no condition to fight against the tongue-thing that was still licking at the entrance to her already soaked pussy.

 

A few licks later the tongue dipped inside her pussy and ran over her clit. She gasped, twisting her hips trying to get away from whomever or whatever it was when the licking suddenly stopped. A moment later she felt something straddle her. A sickening feeling of horror passed through her as she realized it could only be Thunder.

 

The licking resumed with much more enthusiasm when Thunder had Cindy trapped beneath him against the edge of the tub. She couldn’t move but at least she could breath finally. She shouted out, loudly, hoping it would frighten the dog away but it didn’t do any good. Her cries and shouts were intermingled with moans as Thunder licked at her clit and tongued her pussy.

 

Her revulsion grew as she felt what could only be his penis hardening and emerging from it’s sheath and pressing against her back. Thunders tail wagged excitedly, smacking her in the head as he licked her to orgasm.

 

When he dismounted, Cindy tried to gather her legs up under her and escape but he was much too quick for her. Within moments he turned himself around, jumping up on her and pressing her back down against the edge of the tub as his paws landed above her shoulders.

 

She could feel him humping a few times, trying to find her pussy but he wasn’t hitting his mark. She felt slightly better about that, thinking she had a good chance he wouldn’t but she still had to get away. She twisted her hips, trying to wriggle out from under him, still shouting and telling him to get down. All this did was excite him further and he started to bay long and loud.

 

Cindy rose up a bit and thrust back a bit, trying to throw Thunder off of her Just as he pushed forward. She screamed out loudly in pain and disgust when she felt him enter her in one long swift motion as he found his target.

 

He road her hard, pistoning in and out of her roughly stretching her cunt with his huge cock and drowning out her sounds of protest with his constant baying. Tears soon joined the rising water in the tub as Cindy was raped by her inherited dog and she was starting to wonder at just what the sweet old lady had meant exactly about Thunder being good for her on lonely nights.

 

The thought sickened her further as he continued to fuck her, thoughts of him doing this with that old wrinkled pussy of hers. Cindy braced herself against the side of the tub, wanting to fight against her attacker and she bucked back against him wildly. No one was going to take her without a fight. Thunder’s baying increased dramatically when she started fighting him, and he rode her harder, driving deeper into her cunt and stretching it until he finally drove his knot inside her.

 

Cindy screamed loudly in pain, blood trickling out of her pussy, her body tiring from a hard days work and all the struggling and she lay lax against the tub, sobbing and hoping for this to be over soon. The worst part of it all was she’d never been fucked this good in all her life. She didn’t remember having so many orgasms as this before!

 

Thunder thrust a few more times after he was locked inside her and then he finally exploded, jets of his cum spurting hotly inside her and mixing with her own love juice and the trickle of blood. After a few minutes, Thunder his mounted and pulled free with a pop and retreated into the bedroom to lick himself clean.

 

Cindy sobbed long and hard, slipping into the tub and cleaning every inch of her body meticulously. She was feeling so many things. Defiled. Betrayed by her friend. Both the old lady and Thunder, whom she had quickly grown to love after inheriting him. She felt cheap and dirty and sore. But she felt disgusted too- with herself. It had been very painful, yes, but at the same time it had felt extremely good.

 

She turned the water off and started to massage some salve into her abused pussy and she closed her eyes, relaxing back into the tub. As she touched herself she was unable to help but imagine the mental image it must have made, her dog mounted over her ramming into her for all he was worth. She was wet again quickly and she quickly brought herself to orgasm with her hand. But that wasn’t good enough. Her pussy ached to be filled. Just, not by some animal. No, that was too much even if it had felt good.

 

Cindy stepped out of the tub, heading back into her bedroom to retrieve one of her sex toys, not knowing that Thunder was still in the room. She rummaged through her bedside drawer and Thunders ears perked up as he caught her scent. He stopped licking himself and quietly padded around to the other side of the bed, licking at Cindy’s pussy.

 

She yelled at him again, but he ignored her and he knocked her to the floor. Just as she managed to get her arms and legs underneath her he mounted her, this time hitting her pussy quickly as he was well familiar with it now.

 

Cindy cried in protest at this being done again but her vocalizations quickly returned to moans of reluctant pleasure. This time Thunder was being much more gentle with her. It must have been because he’d cum once already. She moaned and pressed back against him, feeling good and quickly having an orgasm. She was well aware yelling and struggling wouldn’t do her a bit of good so she figured she might as well enjoy the best fuck she’d ever had. The feeling of his fur against her back as he fucked her added to the perverse pleasure of it all.

 

Thunder drove his knot inside her stretched pussy much easier this time and he howled loudly as he came inside his bitch a second time.

 

Cindy lay with him locked together and pushing back against his cock getting herself off as much as she could before his penis shark and exited her cunt. This time Thunder licked her clean since she wasn’t protesting so much and Cindy couldn’t help but think this must be how he got his name because he sure was thunder between her legs!
