Mary woke up, smacking a paw against her alarm clock turning it off. She stretched giving Lucifer's belly a soft rub, giggling slightly when the dog lifted his leg. Leaning in, she licked his ears a bit whispering. 

"As much as I'd like to, have to behave a little until grandma is gone." Playfully pushing the rottweiler off the bed, watching him slide off the bed before just laying down on the floor. "Oh what a lazy ass dog." Taking her time getting up out of bed, she tossed her old clothes into her hamper, grabbing a fairly conservative outfit wanting to avoid her grandma's judging looks. 

Walking down the steps, she didn't even mind with the fact that Lucifer was following her that little nub of his was wagging. Mary's grandma was in the kitchen cooking up some eggs and bacon, she smiled until she noticed the feral rottweiler following behind.

"Did you really have to let him follow you? That's not healthy you know." She rolled her eyes at her grandma's comments, leaning in and kissing her cheek softly.

"Really grandma? He's harmless. He's just following me." Opening the backdoor letting Lucifer go running out into the backyard to do his business. "So you want to tell me why you have such a hate on for Lucifer? He's done nothing to you." Her grandma just grumped finish cooking the breakfast, seeming to ignore her. "Grandma, I'm not dropping this until we've talked about it. I won't tell mom or dad what you tell me."

"You aren't going to drop this until you get an answer are you Mary?" She shook her head watching her grandma, before getting up to let Lucifer in, drying the snow off his fur and wiping his paws. Giving his head a few pats, scratching behind Lucifer's ears telling him to go lay down in the other room. "I can't believe that dog listens to you."

"He listens to anyone who doesn't yell at him, you scared him." Her grandma scoffed at her comment. "You don't think so? He was cowering under the tables yesterday after your reactions to him. He didn't do anything to deserve it." Mary sat down after getting herself a glass of orange juice, waiting on her grandma.

"Fine, but what I'm going to tell you doesn't leave this room do you understand me?" Mary nodded, her ears perking up and didn't believe her grandma was actually going to tell her. 

"I promise grandma, I swear on my promise ring." Holding up her paw, showing off the fact she still had the ring she had gotten a few years ago, promising that she was going to save herself for marriage. 

"I'm surprised you've kept that. Most girls think that it's a dumb outdated idea." Mary just assured her that she was keeping that promise as it was important to her. "Fine, I know you probably don't remember them but my parents, your great grandparents, had a rough patch." She nodded slowly, unsure why she's bring them up. "Well no one really talks about it in the family, but your great-grandaunt isn't your great grandad's kid." 

"What do you mean? I saw the pictures, she looks like him." She was confused this wasn't really making a lot of sense. "I think it has something to do with Lucifer but not directly doesn't it?" Mary watched her grandma nod, wringing the towel between her paws a bit.

"I was six years old at the time. We had a pet." Her grandma was looking down at the table. "You know I'm a third generation anthro, it wasn't that long of our kind being around. So most anthro families didn't live too much differently than the human families around them." She watched those older ears droop, her grandma speaking slowly.

"Grandma, if you aren't comfortable talking about this, I'm sorry." She went to say something else, her grandma raising a paw.

"I think I've held it in for long enough." Mary held her grandma's paw, giving it a light squeeze nodding. "So we had feral dog, didn't really think about it. Dad had taken me out for ice cream and we came home." Watching her grandma close her eyes, voice dropping down to a whisper. "Came home, finding mom and the pet in the living room engaging in obscene carnal acts."

"Oh I'm so sorry grandma." Getting up, she went over and gave her grandma a warm hug gently squeezing her. "I never knew, now I get why you're so angry at Lucifer." 

"It's not him I'm mad at Mary. It's not really fair. He didn't do anything." Nodding, Mary let her grandma get it off her chest. "It's just seeing him, following you. Just brought up a lot of bad memories. Your great-grandaunt is the offspring of a feral and anthro." A blush crept on her cheeks, thinking about what she's been doing with Lucifer not knowing what her grandma had gone through. "Where it happens now but it's still frowned upon but back then?"

"I'm guessing it was a huge thing." She watched her grandma nod slowly.

"Yah, we had to move. Word had gotten around really quick, and things had gotten worse once it got out that my mom was pregnant with the feral's pup. It was unheard of and my dad still took care of the child even though it wasn't his." It had to be crazy, thinking about what they would go through back then since communities were so much more tightly connected. 

"So when I saw the dog, it just brought back a lot of bad memories and then hearing his name just added to it." She nodded slowly, just wanting to let her grandma get things off her chest. "So you said he's a good dog?" Mary nodded and smiled.

"Yah he's well trained grandma. I mean, he's never even gone near my laundry hamper or anything." Her grandma seemed impressed at that comment. "He listens, doesn't pull on the leash if you walk him. He's been a perfect pet. Whoever owned him previously sent him through a lot of training."

"That seems better than most of the dogs I've seen." Mary helped her grandma get up from the chair. "I'm not going to say I'll be a fan of him, but if you say he's a good dog I'll take your word for it." 

"Thank you grandma. I'll make sure he doesn't both you and keep him in my room at night. I mean if you're okay with that?" Her grandma nodded and her nub was smiling as she'd get to have Lucifer in her room still.

"You're my favorite granddaughter." She had to laugh pointing out she was the only granddaughter the rest of the grandchildren being boys. "That doesn't change the fact you're still my favorite." Mary got her cheek pinched and a little wiggle. "Plus, you are a good kid and I trust you not to indulge in those terrible carnal urges that many of your generation give into."

That last comment made Mary feel rather guilty, considering in the last few days since having Lucifer around she's gone down on him and let the dog lick her spade. She wanted to feel bad about it, but there was just something about having someone that could give you that attention that wasn't like the immature boys at school.

She now knew it was a rather questionable thing she was doing, having heard her father's sermons at church and stuff that was around on the internet. It was one thing to fool around with the limited stuff she'd done with Lucifer at this point, but she was determined not to be like other girls or do things that would ruin the vow of her purity ring and promise. Also knowing what she did now about what her grandma had gone through made her resolve not to go all the way no matter what.

Mary took Lucifer out for a walk again before dinner, just going around the other block by her house. Lucifer was behaving, not pulling at the lead which made her happy. She knew a few of her human friends at school who had feral dogs and they complained how they always tugged at the leashes and stuff. Waving at some of the other people that were walking their dog, no one seemed to give her a second glance, helping her soothe her nerves a bit.

After getting home, the rest of the evening was quiet and grandma didn't snap at the Lucifer or anything. A little bit of her felt bad cause she knew that she wanted to try something with the feral dog tonight, having watched a few things on her phone. It took everything she had not to be antsy all night, practically running up to her room when she told her parents and grandma goodnight. She called Lucifer the dog eagerly following her to her room.

It took her no time at all to slip her clothes off leaving her in just her fur, glancing at herself in the mirror. Her black fur covered most of her body, the tops of her c cup breasts had that lovely tannish brown color giving a little contrast. The insides of her thighs to just below her belly was that same tannish brown color, though her black spade making a sharp contrast to her groin. Along her chin and up to the sides of her muzzle had that same tannish brown color.

She turned to look at Lucifer, he was sitting there with that nub of his wagging though that wasn't what her attention was on. Sitting on the edge of the bed, she spread her legs reaching down to stroke above her spade.

"Come here boy." Watching him eagerly step forward, his muzzle brushing against her thighs before that broad tongue snaked out swiping over her spade. Mary bit down on her knuckle to keep from whimpering, each swipe of that tongue just made her feel warmer spreading her legs wider. Slowly she laid back, letting Lucifer work his magic with that wonderful tongue covering her face with a pillow moaning softly into it. Even though what she was doing was terribly wrong and would cause so many problems it felt too good to make her want to stop.

Her fingers stroked the fur on Lucifer's head, rubbing between his ears as that tongue lapped at her spade. She almost whined out too loud even with the pillow when he forced his tongue inside her. Arching her back bucking her hips, could hear Lucifer starting to pant as he kept licking. Mary hugged the pillow to her face, moaning and squirming as that wonderful tongue sent her over the edge orgasming.

"Oh FUCK, LUCIFER." The pillow muffling her cries, squirming and whimpering as he kept licking her making her buck against him eagerly. After a few more moments of that relentless tongue, she had to push him away panting heavily. "O... Okay Lucifer, you can stop boy." She felt her cheeks flush warm under her fur, seeing his rump wiggling with that tail nub wagging even as his muzzle was soaked in her juices.

There was no doubting that the feral dog was a fan of her taste, seeing his cock already fully free of it's sheath and hard. Catching her breath as she smiles at her immoral lover. Moving onto the floor, she gently uses her paws to push on Lucifer's side the dog laying on his back. Gripping his shaft by the base, holding it up as she leans in inhaling that thick musky scent. She slowly slobbers her muzzle along his pole, getting it slick with her saliva before leaning in hugging his cock gently between her breasts.

Closing her eyes, she hugging her breasts tightly against Lucifer's cock stroking him between them. Her ears were perked up, listening to the feral rottweiler panting heavily and she was sure he was clearly enjoying the attention. She slowly speed up feeling that warmth between her breasts, feeling the tip occasionally brushing against her muzzle letting her tongue slip it of her muzzle licking at Lucifer.

"That's such a good boy, you like that don't you?" Mary could swear he could understand here even though she knew he couldn't other than the inflection of the tone she used. It was fun doing this, knowing he wouldn't tell anyone. She was aware he was starting to get close with the bulge of his knot swelling at the base of his cock. It wasn't long before Lucifer grunted, the dog's hips jerking under her. Her tongue licked at that squirting tip as he soaked her muzzle and breasts with that sticky musky smelling cum. A few more thrusts and he started to whimper slightly and she let Lucifer slip free from between her breasts.

Mary looked at her breasts, feeling her heat under her fur realizing that Lucifer soaked her face and breasts. Her nose sniffed slightly and licked her muzzle clean. 

"Oh damn. I'm going to have to shower before talking to anyone." She looked at the feral rottweiler, licking himself slightly as his cock was softening sliding back into that sheath. "I stink like you and think they'd realize what we've been doing and I really don't want that." Crawling over to Lucifer, she leaned in and licked his muzzle getting a few licks in return her little tail nub wagging. Slowly she got up, lifting the blanket and getting under the covers. "Mmm come here boy." Mary felt a comfort with Lucifer's warm body against hers under the blanket drifting off to sleep.
