~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Autumn and Yin were walking home from their wedding, both of them holding each other's hands happily. Autumn then blushes slightly as she feels a wetness pooling in her underwear and a warmth in her core. Her tail instinctively goes between her legs in embarrassment as she stops walking, Yin looking at her curiously. "What's wrong, love?" Yin asks his fox demon wife, noticing the blush on her face and the look of shock and embarrassment she had. The fox demon hybrid whimpers quietly, too embarrassed to speak.

Yin then looks down and notices Autumn's tail between her legs, and he blushes slightly when he realizes that she's in heat. "Ah, fuck. I'll make sure we get home quickly," Yin says, to which Autumn hugs Yin close. "Thanks..." Autumn whimpers, to which Yin nods in response. "Would ya like me to help you set up the closet so you can spend your heat in there again?" The silver demon asks his wife, to which she shakes her head no. "I-I'd like to mate with you..." Autumn says, to which Yin blushes brightly in response.

"A-are ya sure ya want to do this?" Yin asks hesitantly, to which Autumn nods. "Y-yes, I-I need you Yin! I've been waiting for us to get married before I wanted to mate with you, but now that we're married, I can truly call you my mate!" Autumn says, rubbing her legs together impatiently. "O-ok then," Yin eventually says with a nod, before he picks up Autumn bridal style, which causes Autumn to squeak in embarrassment, and he then carries her home. As soon as they get home, Yin places Autumn on their couch and climbs on top of her, which causes Autumn to blush brightly. Yin then leans down and starts kissing Autumn's neck, to which she whimpers quietly.

After a little bit, Yin starts biting Autumn's neck, which causes her to gasp and moan in pleasure. Yin then starts reaching his hands down and starts undressing Autumn, leaving her in only her bra and panties, which causes her to blush brightly and squirm slightly in anticipation. Yin then starts kissing and biting down towards Autumn's chest, leaving hickeys all the while. He then stops at her bra and looks up at her. "Can I please take off your bra?" Yin asks, to which Autumn nods in confirmation, to which Yin then tries to unclasp her bra, which causes Autumn to giggle and helps him unclasp her bra before she takes it off and Yin grabs it and throws it to the side of the room.

Yin then looks at Autumn's chest, blushing brightly as he looks at her boobs, which causes Autumn to blush as well as she squirms and whimpers again. Yin then gently grabs one of Autumn's breasts in his hand and starts squeezing and kneading it, which causes the fox demon to gasp before moaning loudly. Yin then leans down and starts kissing Autumn, continuing to play with her breast. Autumn kisses back, letting out muffled moans as her breast is being played with. Eventually they both break away from the kiss, both of them panting as a string of saliva connects their mouths.

"Y-Yin, I-I need you please~," Autumn says pleadingly, to which Yin chuckles and stops squeezing her breast and lowers his hand down to her crotch. He brings his hand into Autumn's panties before he starts rubbing her clit, which causes her to gasp before moaning loudly. Yin starts collecting his wife's juices on his finger, smirking at just how wet she is. "Damn, you're really wet down there, Vixen~," Yin says seductively, which causes Autumn to blush brightly and squirm as Yin keeps rubbing her clit. Eventually he sticks his finger inside Autumn's pussy, which causes her to let out an extremely loud moan in response.

Yin waits a little bit for Autumn to adjust to the feeling of his finger inside her womanhood before he hears her start whimpering and she starts squirming in anticipation. "Y-Yin~! P-please move your finger~!" Autumn says as Yin pretends to think for a moment before he smirks. "Beg for it, Vixen~" Yin says devilishly, which causes Autumn to whine. "P-please move your finger~! I need you~!" Autumn says, trying so hard not to moan but failing miserably. Yin smirks again as he starts thrusting his finger in and out of Autumn's womanhood, causing her to gasp before moaning loudly in pleasure.

Eventually Yin puts a second finger inside Autumn's pussy, causing her to gasp. Yin waits a few minutes before he starts thrusting his fingers again, kissing Autumn's neck sweetly to try and make her more comfortable. Every so often he would scissor his fingers inside Autumn's womanhood, trying to stretch her out, which causes her to moan loudly. Eventually he hits her sweet spot inside her, which causes the fox demon to gasp before practically screaming in pleasure, arching her back, which causes Yin to smirk when he realizes he found her sweet spot. He starts continually thrusting his fingers into Autumn's pussy, aiming his fingers towards her sweet spot in hopes of making her cry out in pleasure.

After a few minutes, Autumn starts trembling from the amount of pleasure she was receiving. "Y-Yin, I think I'm gonna cum~!" Autumn says shakily, to which Yin uses his other hand to gently rub her thigh as a sign that she was allowed to cum, using his thumb to rub her clit to get her closer to her orgasm faster. After a little bit, Autumn cries out in pleasure as she has her first orgasm, her juices puddling onto Yin's fingers and her panties, Yin still thrusting his fingers in and out of her, riding out her orgasm. After her orgasm finishes, Yin pulls his fingers out of Autumn's womanhood, which causes her to whimper at the loss, still feeling horny. "Don't worry love, I'll make sure ya feel great~" Yin says seductively, which causes Autumn to blush brightly as her lover slowly removes her panties from her legs, smirking as he notices how wet her panties are.

"Damn, Vixen, your panties are bloody soaked, aren't they~? You naughty Vixen~" Yin teases, which causes Autumn to let out a huff of annoyance. "Y-you caused this..." Autumn says with a pout, which causes Yin to chuckle. "I know, I'm just teasing ya~" Yin says before getting up from on top of Autumn and starts removing his clothes, slowly and teasingly removing his pants as Autumn watches in anticipation, blushing brightly and quietly whining when she sees Yin's erection through his boxers. Yin then takes off his boxers, which causes his erection to spring free from its constraints, a bead of precum leaking from the tip. Autumn practically drools when she sees Yin's dick before instinctively getting on her hands and knees, her tail wagging in anticipation, which causes Yin to chuckle.

"You seem pretty eager, darling~, but I'd actually like ya to lay on your back please~" Yin says, to which Autumn hesitates before doing what she's told and laying down on her back. Yin then spits on his hand to use it as lube and strokes his cock before he crawls on top of Autumn, which causes her to blush as he aligns his cock with her entrance. "Now, are ya sure ya wanna do this?" Yin asks Autumn, to which she nods in response, which causes Yin to chuckle. "Alright then, Vixen~" Yin says before he teasingly starts partially thrusting his cock towards Autumn's entrance, but not entering her womanhood, which causes her to whine, causing Yin to smirk. Yin then slowly pushes the head of his cock into Autumn's womanhood, causing both of them to shudder and moan quietly.

"Please tell me if I need to stop if it hurts too much," Yin says, in which Autumn nods in response before Yin starts slowly going deeper before he hits Autumn's hymen and then looking at Autumn. "Are ya ready?" Yin asks. "Y-yeah," Autumn says, and then Yin pulls out before quickly pushing himself back in, breaking Autumn's hymen, which causes the fox demon to yelp in pain and tear up slightly. Yin wipes away Autumn's tears and starts whispering sweet words to her to try and calm her down. Eventually Autumn let's out a whine.

"Y-you can move now, the pain is going away," Autumn says, to which Yin nods and slowly pulls out before thrusting back inside of Autumn's womanhood, which causes her to moan in response. Yin starts making a rhythm with his thrusts, causing Autumn to moan loudly as her mate does this, her body being moved with the motion of the thrusts. "You're so tight, Vixen~. So wet too~" Yin says seductively as he grunts and keeps thrusting into Autumn, gently grabbing her hips to keep her in place as he keeps thrusting into her pussy. Yin then reaches his head towards Autumn's chest and takes one of her nipples into his mouth and starts sucking and biting it, which causes Autumn to moan even more. Yin then takes Autumn's nipple out of his mouth and leans his whole body against Autumn's body gently as to not accidentally put too much of his weight on her, their chests touching each other as Yin keeps thrusting into Autumn, the fox demon moaning all the while.

Yin the starts passionately kissing Autumn on the lips, to which she kisses back, both of them letting out muffled moans and groans of pleasure as the sounds of skin smacking skin fill the room. Eventually they break away from the kiss as Autumn lets out a loud moan as Yin hits her sweet spot. "Y-yes~! R-right there please~! H-harder~! F-faster~!" Autumn moans loudly, to which Yin nods and continues his thrusting, going faster and harder, angling himself so he hits Autumn's sweet spot, the fox demon letting out loud moans in response, both Autumn and Yin moaning each others names. "I-I'm gonna cum again~! Please breed me~!" Autumn says, to which Yin smirks. "I'm close too, love~" Yin says with a grunt as he keeps thrusting.

Eventually Autumn practically screams in ecstasy as her second orgasm comes along, her juices squirting onto Yin's cock as well as the couch. After a few more thrusts, Yin ends up cumming inside of Autumn's womanhood, his seed shooting deep into her womb, Autumn moaning loudly at the feeling of the warmth. As Yin was about to pull out, Autumn stops him. "P-please keep it in for a bit! I love the feeling of your cum inside me!" Autumn says, to which Yin chuckles and nods in response and keeps his cock inside of his mate's womanhood. After a few minutes, Yin eventually pulls out, Autumn whimpering at the loss as some of Yin's cum dribbles out of her womanhood.

Yin lays down next to Autumn and brings her close to him and cuddles her. "So, how was that for ya first time~?" Yin asks, to which Autumn blushes and smiles. "It was great," Autumn says, which causes Yin to chuckle in response and grin. "I'm glad. If ya end up needing me for the rest of your heat, don't hesitate to tell me, Vixen~" Yin says, to which Autumn nods in response with a blush. "O-ok," Autumn says in embarrassment, which causes Yin to chuckle.

~One Month Later~

Autumn was inside her and Yin's closet, putting things in there to make a nest. She didn't really know why she was doing this, she just felt the urge to do it. She had also been vomiting a lot recently and having mood swings as well. She was currently home alone when she heard a knock at the front door. Autumn stops making her nest and rushes to the front door and opens it, revealing Wei, Yin's adoptive younger sister. "Oh, hi Wei," Autumn says.

"Hi Autumn!" Wei says happily. "You can come in if you'd like," Autumn says as she steps out of the way for Wei to come inside, which she does. "Thanks!" Wei says as she walks inside the house, a shopping bag in her hand. "What's in the bag?" Autumn asks curiously, Wei than looking at the bag she was holding then back at her sister in law and smiling. "Oh! Yin asked me to check on you for him while he went out today! He told me that you've been throwing up and having mood swings so I thought I'd buy these for you!" Wei says before handing the bag to Autumn, who looks inside bag curiously before taking out one of the small boxes inside it and reading the front.

"A pregnancy test...? I highly doubt I'm pregnant, Wei, its hard for human demon hybrids like me to conceive children..." Autumn says, to which Wei gently shoves the fox demon hybrid to the nearest bathroom in the house. "Oh nonsense! You were in heat recently, right? If that's the case, and if you and Yin ended up doing the deed, then that must mean you were more likely to conceive due to being in heat! Plus the symptoms Yin told me you're having are two common symptoms of being pregnant!" Wei says as she opens the bathroom door and gently shoves Autumn inside the bathroom, who had been blushing slightly at what she said. "B-but I don't know how to use a pregnancy test!" Autumn says. "Its simple! You just pee into it and then put it down on a flat surface and wait for a few minutes and then it'll show the result! I bought a couple just in case!" Wei says before closing the bathroom door in front of Autumn to give her privacy before she waited for her to take the tests. Autumn sighs as she decides to use the pregnancy tests she was given.

~A Few Minutes Later~

Autumn stands in the bathroom in confusion, looking at the pregnancy tests she used sitting on the counter. "Are you ok in there?" Wei asks, growing concerned when her sister in law didn't answer. "I'm coming inside the room," Wei says before she opens the bathroom door and walks inside and walks over to Autumn. Autumn looks over at Wei in confusion. "What do the two lines on the tests mean?" Autumn asks, which causes Wei to gasp before she starts squealing in excitement.

"That means you're pregnant Autumn!" Wei says excitedly as Autumn looks at Wei in shock. "B-but how? I thought it was extremely uncommon for demon human hybrids to conceive children!" Autumn says. "You must be one of the lucky few people then!" Wei says happily. "What will I tell Yin?! What if he ends up hating me?!" Autumn says, worry evident in her voice. "Just tell him the truth, I'm sure he'll understand! I bet he'll even be happy about it as well!" Wei says.

"A-are you sure, Wei?" Autumn asks nervously, to which Wei nods. "Of course! I know him well enough to know that he'll probably be super happy about it!" Wei says happily. "O-ok. Do you know when he's coming home?" Autumn asks. "He should be here any minute now," Wei says, and right as she says that, her and Autumn hear the front door open before hearing two familiar voices. "Vixen, I'm home! Jin is with me too! Where are ya?" The two women hear Yin say from the living room.

"I-I'm in the bathroom with Wei!" Autumn calls out to her mate. Jin and Yin then walk into the bathroom. "What's going on? Why are you two both in here?" Yin asks curiously, to which Autumn looks nervous. "W-well, I need to tell you something important..." Autumn says, which causes Yin to tilt his head out of curiosity. "Well, what is it?" Yin asks Autumn.

Autumn turns around and picks up one of the pregnancy tests and hands it to Yin nervously. Yin takes the test and looks at it for a few minutes before looking up at Autumn, a look of shock on his face. "Y-you're pregnant?" Yin asks in shock, to which Autumn nervously nods. Yin then hugs Autumn excitedly before picking her up and twirling her around the room. "I'm gonna be a father!" Yin says excitedly, which causes Autumn to smile slightly and tear up happily.
