"Ewww Adam wet the bed!!!" Fay exclaimed as she caught sight of her brothers dark stained pyjama bottoms,

"Did not!" The young wolf cub retorted.

"Okay, okay, calm down, it's OK." Elisa entered the twins room wrapped in her long nightie.
"Fay, don't be mean to your brother, we all have accidents. Let's get this sorted." She pulled the blanket further back and got a waft of something. Something she hadn't smelt in a long time.
Since before her husband had passed away in an accident out on the wells.

The wolves lived in a sparse town which existed as a truck stop for those heading to the big resource extraction sites - oil, gas and minerals filled the area. The hostile climate of the near arctic keeping any real population growth down.
She worked and owned a small general store, he had been up to work on the oil fields.
One thing lead to another and like so many women of the town she found herself pregnant and promptly married. They'd been happy together, he'd been a loving and kind husband.
Unfortunately a freak blizzard hit the area while her husband was out on it, he and four others died when their off-road vehicle was blown off a small raised track and rolled. He'd been lucky in dying from a broken neck in the roll. The others not so much, freezing or bleeding to death.
Being suck a transient and small population education was limited to the basics and that needed to keep the town running.

Now she was going to have to teach her cubs biology.

"That, that's not wee. It's, it's sperm." She dragged a finger over the drying cum on the bed confirming her suspensions.

"It's all sticky!" Adam complained.

"I know, Adam take your pyjamas off and we'll get them in the wash with your sheets." The elder wolf started to strip the bed as her son stripped.

"Why's his willy all funny?" Fay cocked her head and pointed her her brother's erection.

The family where used be being nude together, living in the rooms above their shop space was tight, and the twins shared a room still.

"It's an erection honey. Just, wait a moment, and I'll explain." She bundled the soiled bedding and pyjamas up and went to set it all for the wash when she paused in the door.
"Fay, sweetie, can you take your nightie off too? I'll get it all done in the wash" she had had an idea. Sex education was, like many topics, dealt with on an as needs basis. Many learnt about sex either from exploration with peers, or a family member explaining it (usually after being caught exploring things). Now was a good a time as any.
Taking her daughter's nightie she dropped everything in the basket to be washed.

"Remember a few months ago when Fay started to bleed from her fanny? And I said I'd explain more later as I was running late. Well, I have lots of time today. So, we're going to learn about sex."

She didn't know how much time passed as she explained sex, using the cubs and herself as anatomical props. She answered every question to the best of her abilities.

Finally running out of questions the trio sat on contemplative silence.

"So. I can be a mummy now? I can get pregnant. And Adam can be the daddy? Make me pregnant?"

"Yes, you can get pregnant and be a mum if you want, and yes, Adam can get you pregnant if you have sex or his sperm gets inside you."

The two considered this.

"I want to be a mummy. I want to be pregnant. Miss Josie from the pharmacy is pregnant, and she looks really pretty. And miss Johns. She looked really pretty when she was pregnant."

"Well, you'll need to find someone to get you pregnant then, which may be some time."

"I want to make her pregnant. I think I'd make a good father and... I think Fay is really pretty. She makes me feel all funny inside, especially when I see her naked and I want to touch her, and when we touched each other I felt really good"

"Oh...err, oh. OK" Eve hadn't expected that. The twins where close but she didn't know they where exploring each other, or even interested in each other in that way. Then again, they spent a lot of their time alone up here when not at school or helping around town.

"well, ok. Fay if you just climb up here and get on all fours. It'll be a bit easier this way, we can do other positions later. We'll start with the classic first: doggy style, it's how our ancestors, especially ferals, mate."

Fay hopped up onto the bed and got on all fours next to her mother.
She was starting to fill out, a slight bump on her chest where breasts where forming, what would hopefully be wide child bearing hips like her mother, maybe the seizable chest too, although that would come with having cubs too. A fine down of pubic fur was starting to cover her sex, the mound still prominent under the soft fuzz.

"Scoot over, your brother needs to get up behind you too." She could feel herself getting wet at the prospect of making her cubs mate, watching them take each-other for the first time, then again and again. Hopefully Adam would knock Fay up, and then her, they could start a family, move to one of the distant cabins.
She and her husband had talked about it, getting some of the girls and boys in the town to work for them, after all, it was lonely for the men out amongst the oil wells, mine shafts and logging camps. Services to these lonely men where how many young ladies met their future husbands.

"Adam kneel behind your sister, just there." She patted the bed "Fay, spread your legs a little so Adam can get between them, just like that."

Fay wriggled to spread her legs and knees wide enough for her brother to get between them. Looking back at her brother over her shoulder, tail flicking slightly over her firm young ass.
Eve desperately wanted to climb up and have the wolf cub eat her out as her son fucked her virgin cunt.
The wolfess knew that she couldn't, not yet. She would be best sitting to the side, watching, instructing there cubs, reassuring them, especially when he tied the bitch he was going to breed.

She remembered her first tie, how scary and strange it had been. Neither of them really knew what was happening, thankfully his father had heard them panicking and reassured them both, giving them a lesson in the facts of life. The situation would have been embarrassing if not for how upset the two young lovers had been.

Adam kneeled between his sisters legs, slowly touching her pussy, his other hand stroking his prick.
When he caught his mother looking he stopped and looked embarrassed.

"Sorry"

"No no sweetheart, it's OK. It's good to do that. See how your sisters fanny is getting all puffy? How she's moaning slightly? It means she's enjoying it and really to take you. All that new sticky stuff coming out your willy? That's a special thing boys make to help make mating easier, it makes it easier to put yourself in her. Fay, honey, do you think you're ready for Adam to mount you? You want to be pregnant? Have your brother as your husband maybe?" Her last two questions caused her daughters hiked up tail to start to wag harder,

"Yeah! I want to be pregnant and be a mummy! And if I can marry Adam and you we can have lots of cubs and all sleep in the same bed all the time and cuddle!" Fay was clearly very excited at the prospect, and so was Adam, who's tail was going as hard as his sisters.

"I want to be your husband mum! And Fays husband too! If I'm you husband too, and I get Fay pregnant, can I also get you pregnant too?" Adam enthused.

It was adorable how willing and eager the two wolf cubs where.

"Yes you can Adam, but, let's leave that for another day, we have so much to explore now" she smiled and muzzed his head fur.

"To mate with your sister you need to put your willy in your sisters fanny. Now, in this position it may be easier if you hold her hips, I'll help guide you in." She grasped her son's young erection, slowly guiding the wolf pups pointed tip to her sisters entrance.
She stopped before he could properly get in, just wresting the tip at her daughter's entrance.
"No just slower push in, gently, if Fay asks you to stop or slow down, or pull out, do that. Having something in your fanny for the first time can feel really nice but very funny too."

"Like this?" The young wolf slowly pushed his hips forward, his small cock sinking bit by bit into his twin sister.

"Ohhhh... That feels niice"' Fay gasped, her brother's cock still small, he was a cub after all, but he was just the right size for her, she felt strange as he slowly entered her virginal pussy, gently stretching her out.

She felt something soft and warm against her butt, looking over her shoulder, then between her legs, it seemed her brother's hips where all the way against her!

"Oh good girl! Taking your brother in all the way first time! How does it feel? Do you think your brother can start to move, so he can breed you?" The wolf mother cooed to her daughter, who nodded enthusiastically.

"Yeah! It feels so good! I really like how he feels in me. Especially when he was moving! I want to be a mummy! Please Adam! Please breed me!" She begged back to her brother.

"Ok Adam, slowly pulls back and forward as far as you want, listen to how your sister moans and begs for you to breed her. Do it Adam... Hump your sister"
The young wolf boy started to draw his small shaft back and forth, deep instincts guiding him he started to speed up, little hips pistoning hard against his sister.

"Oh! Ohohoh! Oh Adam! Yes!" Fay moaned and wailed as her brother fucked her. He hunched forward, wrapping his arms around his sisters tummy, bucking desperately like a feral would. The twin cubs panted in unison, whining and grunting with desperation.

"I feel funny! It feels like... I'm gonna" Adam couldn't articulate what he felt before he shoved home, his small knot inflating and linking him to his sister. Virile young wolf seed started to splatter into his sisters young pussy, to make it's way to her fertile womb.
He bucked and humped a few times more as his sister made a strange moaning grunt, shuddering and clenching around his trapped cock.
Her arms gave out under their combined weight, the two young lovers collapsing onto her bed, panting in delight and joy.

"Oh well done! Well done! You're breeding! You're mating! Hopefully soon you'll be full of puppies Fay, you'll be a daddy Adam. It sounds like you both really enjoyed it to!" Eve had been watching, she really wanted to touch herself as she watched her young cubs mate but didn't. She wanted to make sure they where happy and safe. She could teach them more with her body later.

"Yeah, feels so good..." Adam moaned. "but stuck..."

"It's your knot silly, mummy told us this would happen... You're so warm and big... I feel funny, in a good way..." Fay mumbled from under her brother, basking in the new found joy of orgasms.

"Oh yeah... You feel really good around me Fay. I hope I get you pregnant. You'll be a great mummy, I hope I can be a good daddy and husband... I love you Fay. You're the best wife... Sister... Mummy? I could ask for." He nuzzled gently at his sister's cheeks.

"I love you too Adam. You'll be great. You're a great... Husband and brother" the pair lay in silence, basking in the afterglow.

Eve watched and planned. So many possibilities... So much to do.
