Katherine tapped her hand against the couch, sighing. This was getting ridiculous, she couldn’t believe the two kids she was babysitting that night still weren’t going to sleep. It was around 10pm, way past their bedtime. This was the second babysitting job she had that week, usually she had more but with the summer ending, lots of kids were going on vacation. She needed the money while she was at college, but didn’t mind having some time off to herself- she really needed it. It gave her sometime to date around as well, something she hasn’t been able to do for years. She desperately needed something in her life- she was getting way too horny. Even that morning, she had touched herself in the shower, imagining a big man holding her, fucking her from behind. She had washed herself thoroughly after, but she was still kind of worried someone would be able to smell her.
Katherine was good looking by any standards, she had long blonde hair, a beautiful smile, had long graceful limbs and a tiny stomach that went out into large hips, hips that a lot of guys liked to check out in passing. The problem was- she was antisocial, and liked to keep to herself and study most nights. This meant she had a hard time meeting anyone, and this made her super needy sexually.
“Come on! Time to sleep you naughty kids!” She screamed at them, ushering them into the bedroom.
“But Kathy…” The 4-year-old girl pouted. “I miss my mommy.”
She looked at the time again, “She’ll be home any second now. And she’ll be mad if you don’t go to sleep.” She tsked, and put the covers over her, telling them a bedtime story and letting them finally shut their eyes. “Oh, finally.” She whispered.
As soon as they started snoring, she shut the door and walked to the living room, texting her friend and complaining about how tired she was from these two kids. “Save me.”
“LOL. Coming ASAP.” Her friend replied. With that, she turned her screen off and walked to the bathroom, needing to relieve herself after playing with the kids for so long.
As she arrived, she gasped slightly, scaring herself when she saw the family dog, a beautiful pure-bred German Sheppard. She loved dogs, loved petting them and they seemed to love her, too. It was mostly the boys as well, they loved coming up to her to sniff her and she wanted to play with them as much as she could. The German Sheppard- his name was Bear- was sleeping most of the night, and was barely there when she was playing with the kids. He approached her now slowly, and she laughed, petting it, “Aw, you scared me bear. Don’t sneak up on me like that.” He whined at her and nuzzled into her hand as she pet him.
He was huge, way bigger than most dogs she’s seen, and when she tried pushing him out of the bathroom, he refused, continuously whining. She looked at him, then at the door, “Okay, I guess it’s fine if you stay with me- just don’t tell your mom and dad.” She chuckled. She pulled down her pants and panties, and sat on the toilet, humming. It was definitely distracting with a dog staring at her, but she didn’t mind much. After she relieved herself, she wiped and flushed the toilet- before she could pull up her pants though, the dog approached her, sniffing eagerly. He sniffed her crotch over and over, bobbing his head up and down. She giggled at the sensation of his hot breath against her, the most she’s felt on her for years. Oh god Katherine. Don’t think like that- it’s a dog. She reprimanded herself. She was about to shove him away and pull up her pants when she saw it- his pulsing erection. It was huge, way bigger than she’s ever seen in a guy or in porn. It looked just like a man’s penis except for the huge knot at the end, also pulsing away. “Oh dear…” She commented to herself. “I guess the smell from this morning is still noticeable.”
She blushed, she couldn’t believe she had this kind of effect on a dog. She wondered if men could smell her as well- how much of a slut she was. At this thought, her vagina got extremely wet and soaked itself. Bear got harder when he smelt her, whining and nudging at her repeatedly. He wanted her bad, his instincts getting to him- she was no longer a human guest in his house anymore, but something he wanted to mount. She gasped, “It’s like I’m in heat for you, huh? You want to fuck me that bad?” With that, he licked her a few times, and she tangled her fingers in his brown and black fur, moaning. “Oh, that feels really good, you know your way around a woman, huh?” She giggled to herself, but stopped to moan more when he got to her clit. She looked down at him, considering. “Am I really going to do this?” She was worried he wouldn’t be hard anymore after a while, and she would have missed her opportunity. She remembered what she saw in biology class about how dogs mounted each other, and bent down, holding the bathtub to support herself and stuck her butt up in the air.
At that, Bear knew exactly what to do- this was the signal he needed. He placed his front paws on her back, and she grunted at his heaviness, she was worried now, would he know when to stop? What if he was too strong for her and hurt her? She didn’t have time to second guess herself though, Bear inserted himself into her in one smooth stroke, and panted as he started fucking her hard. This was more than she signed up for, she had no idea he was this big, and it felt fucking amazing. She screamed out loud at this, and had to stuff her hand inside her mouth just in case she woke the children up. His knot entered her, and it was so large it hurt at first, but she adjusted and became used to it. She was tight, and she knew he was enjoying himself. He was focused on mounting her, entering in and out, in and out over and over as he grunted and panted from the exertion. She mewled over and over again, taking his dick inside of her, unable to think clearly anymore. His paws slipped against her back as he pounded, and it left scratch marks against her. She was too turned on to care anymore, and the pain turned into pleasure in her mind. Soon, he was unable to take anymore, and with a few final thrusts, he came inside of her, his cum dropping down her body and onto the floor as he thrusted into her a final few times and popped out.
She was unable to move, and she fell onto the floor on top of the cum, breathing heavily. Bear was fine, he breathed a few times and licked her legs gently, consoling her and treating her like a lover. It seemed she had lost track of time- she heard the door open, and she gasped as she rapidly put on her clothes and wiped the floor and her thighs with lots of tissue, her heart pounding away. “Oh god, what have I done?” She muttered to herself. After she cleaned up, she put her hand on the doorknob, looking back at Bear, who was now licking his own crotch. “Same time next week?” She laughed, and left to say hello to the parents and collect her pay.
