She woke up by a text message vibrating her phone on the nightstand, blushing with her paws wrapped around Lucifer giving his ears a lick. The young girl having had rather heated dreams of doing things she shouldn't have with the feral canine. Laying back on her bed, she patted her chest and felt Lucifer crawl on top of her. She scratched his ears watching as the rottweiler pressed his head into the attention.

"Someone likes that." Her legs were spread and he was laying between them, she could feel the warmth of his sheath against her spade, the sensation making her shiver. "Too bad we don't have more time before mom and dad get home." Mary stroked her paws down along Lucifer's back licking his muzzle. Closing her eyes she savored the affection, opening her muzzle when he tried to lick inside. She was so absorbed in the kiss with Lucifer she didn't really notice the feeling his sheath firming up against her slick spade, her dreams leaving her rather heated and wet between her legs.

"Mmm Lucifer, you feel so nice." She enjoyed the warmth of his solid body on top of her, still slowly waking up and giving a little groan. Her fingers rubbing his back sharing a somewhat sloppy kiss, feeling his sheath rubbing against her spade and whimpering lightly. Mary felt him hunch up against her, gasping lightly and then her eyes shooting open. "oh fuck..."

He was inside her and she could feel what felt like a few inches pressed past her spade. She whined slightly realizing that she'd broken her promise to both her grandma and god. Even with that guilt nagging at her, she hated to admit it felt really good. She owned a toy that she'd used a few times before, but this was so much different. It was a warmth that was more intense than her own body but at the same time felt cooler. It didn't help that he was twitching inside her, she could tell that Lucifer's heartbeat was racing slightly. Looking at her, biting her lip.

"Such a bad dog, why do you have to feel so good?" He was panting and she knew he didn't know any better, to him she was just his eager bitch who wanted his attention. A part of her asked herself if that was really the wrong answer though, her paws hugged him gently. Closing her eyes and took a deep breath, she whispered softly to Lucifer. "Much as I want to keep going puppy, I have to ask you to get off." 

It took a little push but Lucifer slowly stood up on the bed, a little moan escaping her lips feeling his cock sliding free of her spade. Her eyes watched the way that her dark spade clung to Lucifer's glistening red cock as it pulled free. Even though she'd seen Lucifer's cock before, to her it looked different now that it was coated in her own arousal. Lifting a paw she stroked Lucifer's muzzle scratching under his head a bit getting him to lift that broad muzzle.

"That's a good boy." Feeling the bed shake a little, knowing that his nub was wagging hard enough to shake his rear end a bit. "Silly." Moving up to a sitting position, she sighed a little shooing him off the bed watching him heading out into the hall. She'd forgot she'd left her door open last night but it was okay since there wasn't anyone else in the house currently.

Getting off her bed, she felt bad that she wasn't paying attention and broke her promise. Looking at the ring on her finger, she was torn cause on one paw she'd promised she wouldn't sleep with any guys before marriage and technically Lucifer isn't an anthro or human guy. Mary went to the shower, turning the water on a bit hotter than she normally put it feeling the slight burning sensation as the water soaked through her smooth coat of fur.

It was a bit uncomfortable, but she felt like it was deserved with the fact she broke a promise that she wasn't intending to and that she enjoyed it. Leaning her head back, just letting the hot water soak her down before she grabbed her shampoo to wash herself off even though it wasn't enough to wash away the pangs of guilt she was still feeling. She should have stopped Lucifer when she realized what was happening, but it shouldn't have gotten that far in the first place.

Stepping out of the shower, she glanced at her phone seeing a message from her parents. They had blown a tire on the way home and were waiting on the roadside service but may be a few hours yet. Drying herself off Mary took a deep breath, going to her room and calling the feral rottweiler.

"Lucifer, come here boy." She knelt down when the dog entered her room, rubbing his ears softly. "We have a few hours of time to ourselves." Feeling the mattress sink slightly when she settled down, she laid back and spread her legs and patted her thighs. Her eyes closed when she felt Lucifer's hot breath wash over her spade before his tongue gave her a firm lick. "T... That's it, such a good boy." Moaning softly as he started to lick her more savoring his attention. This time she let herself give in to the pleasure, lifting her hips against Lucifer's muzzle, reaching down to spread her spade for the hungry dog. "Oh fuck. Don't stop. Please... don't stop." Even though her words were a whisper, they felt like they were echoing loudly in her head trying to block out the bit of guilt she was feeling.

Mary squirmed on the bed, rocking and lifting her hips eagerly against Lucifer's tongue feeling it getting deep inside her spade. Her paws were stroking and rubbing the feral dog's head, calling him a good boy. After a few her words just dissolved into high pitched whines as she bucked against Lucifer's muzzle before crying out loudly. It felt so good orgasming around his tongue, this time a slight spray of her arousal coating the dog's muzzle. She pulled on his head, weakly panting as she whispered.

"Up Lucifer, I need you." Her eyes were still closed as she felt his paws make the mattress sink slightly on either side of her hips. She felt his warm flesh brush against her thighs as he was trying to hit his mark. "Yes, do it please.. Lucifer, please." Ears perking as she heard Lucifer growl as it his tip hit it's mark and his hips thrust forward roughly. She went from being empty missing the feeling of his eager tongue having it replaced by his stiff cock.

It was such an intense sensation, even as he kept rocking his hips forcing that shaft deeper inside stretching her spade around him. Mary bit down on her lip a bit hard, tasting that coppery flavor realizing she accidently drew blood. Reaching up, she wrapped her around arms around Lucifer, rubbing his back as those hips keep stroking his cock in and out of her. She wanted to feel guilty about doing this, but each time he sank all the way inside her making her feel a sense of fullness she'd never felt before pushed those feelings away.

"I wish this didn't feel so good." Moaning weakly between thrusts feeling herself clenching around his firm length, licking back at Lucifer's muzzle. Her legs were lifted and spread making sure that he could get as deep inside her as he could, wanting to feel everything. She was intimately aware of the sensation of his heavy balls lightly thumping against her rump each time he pushed deep, his hips were moving like a jackhammer.

Mary groaned feeling that slight bulge at the base of Lucifer's cock, realizing it was his knot. Even though it was a safe time of the month for her, she really shouldn't go all the way with him though that slight bulge of the knot sliding in and out of her was sending waves of pleasure through her body. Her words kept getting caught in her throat as she tried to tell Lucifer to get down, her hips rocking with his motions. Though once she got the words out, they weren't the ones she should have been saying.

"Don't stop, fucking knot me Lucifer, fuck me!" She hugged him against her licking his muzzle, wanting to experience everything properly for this first time. That knot kept getting bigger as it was now thumping against her spade and Lucifer was growling slightly. His thrusts were a bit ragged but getting rougher and harder. Closing her eyes, bucking against Lucifer as he drove himself forward trying to help him get that knot inside. She whined and then barked out loudly in a mixture of surprise, pain and pleasure as that knot finally slipped inside her with an audible pop noise.

It was such a new sensation, feeling it swelling and stretching her spade making it look obscenely swollen between her legs. She was aware she wasn't going anywhere until Lucifer was done with her. Even with her eyes closed, she saw stars feeling that bulge swollen inside her. Lucifer was still jerking his hips slightly and she whimpered a little.

"Y... you're too big lucifer. Please, stop." Though she pleaded, it was clear that her feral lover was going to finish and nearly another minute that felt like hours to her he was jerking his hips. She folded her ears back when Lucifer snarled loudly, feeling his entire length throbbed inside her and then a sudden wetness was spreading. Mary realized that he was climaxing inside her and that heat spreading through her deepest areas was his cum. "oh god, I can feel it." The sensation caught her off-guard, causing her to orgasm around his length.

She squirmed and wiggled underneath the feral dog, feeling her muscles trying to clench and the stiff maleness inside her making it hard just making her orgasm more intense. Her muzzle hung open moaning loudly and she licked back at Lucifer's muzzle when she felt his tongue, not even thinking. Slowly her breathing returned to normal, opening her eyes to look up at Lucifer leaning in and lick his muzzle whispering.

"Thank you, sweetie. That felt so good amazing. I'm glad I got to share that with you." A quiet moan escaped her muzzle when she felt Lucifer slipped off her until she was just laying there on the bed with him on all fours on the floor. Neither one of them were going anywhere, feeling that knot stretching her still. There were slight aftershocks, feeling his cock occasionally throbbing inside her that warmth was so nice and pleasant. Her fingers stroked over her belly in slight circles thinking about it and realizing why girls at her school liked fooling around with the boys if it felt like this.

Mary laid there staring up at her ceiling, catching her breath feeling the occasional twitch inside her and the only other noise being Lucifer's soft panting. She wasn't sure how long it took before she felt Lucifer giving a slight tug gasping when the knot slipped free. Her fingers brushed over her spade feeling that sticky warmth oozing out slowly.

"I still can't believe I did that. I really shouldn't have." Laying back against the bed, sighing slightly about the fact this time it wasn't an accident that she broke her promise about doing things with the feral dog. Years of the promise ring, what she told her grandma, and listening to her father's sermons at church over the years. She grabbed her pillow, yelling into it. "FUCK." The realization of everything hitting her at once, hating the fact she enjoyed it and knew she'd do it again and the fact she let people down.

"I need to get another shower." Looking at her blanket, seeing the big damp stain and sniffing the air as it reeked of her and Lucifer. Opening her window, she shivered at the icy cold breeze but taking a few deep breaths getting some fresh air in the room before closing the window again. Grabbing her blanket and sheets carrying them to the bathroom to throw them in the washer, getting back into the shower to clean herself up.

Once she was clean, she took the time letting Lucifer out into the yard and throwing some leftovers into the microwave to heat up for lunch. She'd wasted the entire morning being rather intimate with Lucifer. After a bit she left the rottweiler back in, using the towel to dry his paws and body off and then sat down in the living room watching tv.

Her parents got home about forty five minutes later getting up she gave them each a hug, asking how their drive was. Her dad grumbled a bit about the flat tire, but her mom didn't seem too upset.

"It wasn't too bad sweetie. Your grandma wanted to thank you for making her feel more at ease with keeping Lucifer in your room." Mary smiled saying it wasn't really that difficult, he usually just flopped on the floor and slept until the morning. 

"Mary hun, I'm sorry, we may have to keep Lucifer a bit longer. I'm having issues finding anyone at the church willing to take him. They seem fine until they find out he's full grown." Mary hugged her dad and smiled. 

"It's okay dad. He's actually a really nice dog. I know it's a bit much, but is there any reason we can't take him in?" She noticed her parents faces at her suggestion, she raised her paws. "I promise I'll take care of him, clean up after him and everything." She cut off her parents before they could speak up. "I know he'll need vet visits and stuff. I will make sure I have stuff saved from my job to take him for his shots and stuff."

"That's a big responsibility Mary. Plus aren't you worried about what the kids at school will say? I mean, it's really unusual for anthros to have a feral pet." She nodded a bit, her little nub wagging behind her. 

"I know dad. That's their problem. I just don't want him to end up getting dumped off on a family that doesn't want him or anything." Her ears perked up, looking at her parents with a hopeful glance.

"Well your mother and I will discuss it. It's a big responsibility." Nodding, Mary smiled a bit before she settled down to resume watching tv. The rest of the day went pretty quiet until dinner, her parents got her attention.

"Your mother and I spoke about it. If we do let you keep lucifer, he's going to be your responsibility. Means you're going to need to feed him every day, walk him, take him for his shots and get him chipped and registered with the city." She nodded, she was rather surprised that her parents would allow her to keep him, her tail was wagging hard behind her.

"I will Dad, I will mom. I promise." She held up her paw. "I swear I'll make sure to take care of him." Her parents laughed a bit, shaking their heads when she ran over to Lucifer hugging him. "You get to stay here boy, you're my good doggy." Pushing him back playfully when he licked her face with a few wet slobbery licks.

She was so happy, not even for the fact that she'd get to keep her friend and partner but that she'd have his company anytime she was feeling lonely. Mary realized that she might need to take a few precautions to avoid down the line if she wanted to keep playing with him.
