“Wow, that feels... really... weird,” she said, unable to find words for the sheer experience of feeling his penis stop poking around at her vulva and just sink in there. She couldn’t stop this deeper and deeper stretch in her bottom, as she felt herself sliding wide all around the penis that drove into her. “If it feels in any way as good for you as it does for me,” the wolf cub said trailing off in awe, “Your vagina is really... wet, and... and hot, and I’m just sliding into you. You’re rubbing all around me!” “I-I can feel that too,” Millie said, “Your penis’s really stretching me all wet and... nhh! Around.” As his hips hit home, Millie found herself sunk firmly on all fours, her legs stiff. His penis flexed in her, which made her eyes cross from the feeling of it. “So how does my penis... feel, to your vagina?” he asked hopefully. Millie felt fuzzy headed, felt hungry, but she was just... standing here. Just standing on all fours, and there was just a... thing in her. “There’s a thing in me!” she yelped, then scrunched up her muzzle saying, “And I *know* that, but I’ve never felt... sliding, and stretching like that before. I’ve never felt *anything* with my vagina before!” “Just... take as long as you want,” Ozy said unconfidently. Hunched against her rear, with her tail wrapped around his waist, his penis throbbing in that hot, moistening passage, he asked, “D-do you want to mate like... like grownups?” “Ohh, if you squirted *now* it’d just go *into* me,” she said in shocked passion, looking back at her own naked butt. At her non-answer, Ozy started pulling his hips back, again making Millie’s eyes cross at the pulling, then *sliding* sensation, waves of pleasure rippling from her groin as his shaft slowly left her passage. He pushed in again, and they both gasped at the intensity of filling and being filled respectively. Then he pulled out again, and... a slow rhythm of slide in and out began. “Y-you’re really doing it like the... grownups in the movie,” she said with a nervous laugh, trying to deal with the powerful urge rising in her to make this sliding happen more. To get him *deep* in her, and *squirt.* She couldn’t stop thinking about those white jets that left his penis when they were experimenting the other day. Powerful bursts of semen, from the tip of his penis that was now pointed right at her... inside place. “If you squirted in... in me now, I could get pregnant,” she said softly, more mousily than anything she’d ever said before. What was this penis *doing* to her? “Y-yeah,” he answered, but he didn’t stop. If anything he moved faster, making Millie breathe harder at just trying to contain that beast between his legs pushing into her. Big and red and throbbing, and knotted and ejaculating. “A-are you gonna knot in me?” she asked anxiously, hungering for that big knot more than she ever had before. Truth be told he was average sized for a wolf cub, but Millie hadn’t exactly seen many knotted penises before. Her breath caught, as he said, “Y-yeah,” again, and she was rocking against him, because she wanted him to slide in and out, more and more. “Are you g-gonna... squirt in me?” Millie said, hungry for it beyond belief, so much it terrified her. Weren’t they just going to try putting it in? But now that it was inside her, she felt strange. She felt an urge to stiffen her legs, and let him slide in her again and again. The very thought of pulling it out made her hips want him to push in even more! Just when she thought he wasn’t going to answer, he murmured to her, his young voice lost in passion. “I’m gonna put a baby in you, Millie,” he said. Then he *grabbed* her hips and *pulled* himself forward, *slamming* into her, fast as he could pull out. All Millie could do was stare forward in shock and gasp and pant. She felt so hot, her tongue was out, her... paws were sweaty. The sensation was just exploding inside her groin, and he just wouldn’t stop! She didn’t think the hunger could grow any more, but it did. She felt like she wanted to cry, she was so glad that every squirt was gonna go in her. She felt safe with his penis inside her. She couldn’t turn to see Ozy had completely lost it, panting and staring at his orange coated friend, hunched over her rump and thrusting without any restraint. All she could feel was this... thing building inside her that wouldn’t go down. His penis wouldn’t let it go down! Her pupils narrowed as the surge of pleasure from each thrust grew bigger and bigger within her groin. Her gasps rose in pitch, until with a choked yelp it just rushed into her like an electric storm of pleasure. Her vagina throbbed around him, clenching helplessly, and she couldn’t stop! She loved not being able to stop, every clench flooding a pulse of surreally awesome pleasure through her. She couldn’t believe it, she was gonna get the squirts! All she could think about was her pussy as her orgasm eased off. Her pussy full of Ozy’s penis. She could only think about getting him to thrust more, and squirt more, and then he knotted. Ozy pushed deep, and Millie sucked in a breath as that turgid shaft within her started bulging, stretching her wider and wider. She gasped and it grew, panted and it grew, until she felt herself straining to stretch around it. Just a single second of ballooning outward, and Millie completely lost it. Her vagina tried to orgasm, she tried to fuck, he tried to fuck. He couldn’t pull out of her. She tried to get away, knowing that he’d cum right after he knotted, even though she wanted it, and she couldn’t pull away from him. Ozy’s penis was thick and heavy inside her, she was scrabbling at the floor, he was moaning and holding her and biting her ear and she didn’t care. Then his penis started to flex inside her, and throb. An animal moan burst from the young girl, as she felt hot seed burst into her. Every flexing jerk of his penis flooded her with more semen. She was getting a baby inside mer! It was so *hot*. His *penis* was in there, doing this to her! He bit her ear as his eyes rolled back, feeling himself spurting burst after burst of semen into the young vixen, wanting to do this to her, letting it happen inside her vagina, feeling Millie becoming a mommy underneath him and just cumming his brains out. Millie felt like she was stretching inside, as his fluid inflated her even more than his dick, unable to escape through the tight knot sealing her vagina. It was all she could think about, was pushing her butt against his crotch, trying to get more and more semen inside her vagina. Her whole body *needed* to get that pumping penis to squirt all its seed into her and make her pregnant.
After the bursts of semen eased, he stilled against her. It was gonna make Millie’s belly big, and make her give birth and be a mommy, and she couldn’t stop *feeling* it in there. “I—I’m sorry, Millie,” Ozy said in surprising tenderness, “I don’t know what came over me.” “Y-you were just mating, like on the TV,” Millie said, adding hesitantly, “...it happened to me too.” “Are you gonna have a *child* now?” he asked, so amazed that even was a thing. “I–I can feel your stuff in there,” Millie replied cautiously, “I feel really... full of it. I guess it’s changing me into a m-mommy.” He climbed off of her, remarking back there, “I can’t seem to really... stand up like this.” So he remained on all fours, butt-to-butt, as they looked back at each other in confusion. The video hadn’t gotten past the actual climax, so was this supposed to happen? Then Ozy’s penis flexed inside Millie and she felt another weak burst of semen enter her. “I thought you were done?” she asked incredulously. He looked apologetic as he said, “Y-yes, I didn’t tell you it was a little embarassing. There are little... aftershocks every now and again. I’m probably going to be cumming for a while, now.” She tested their join, a delicious stretch, but he held firm inside her. “Your dad’s gonna check on us pretty soon,” Millie said solemnly. “I don’t see any way we could hide this,” Ozy admitted with a wince. The grey wolf cub and the red fox kit remained knotted like that. At a flex and a slight burst of semen in her, Millie giggled and said, “Your penis made some more semen for me.” “S-sorry,” he said with a blush, “It just sort of... does that. I can’t stop it.” “It’s okay, not like I could get any more pregnant,” she said with a roll of her eyes. “I just can’t believe I can fit any more semen in there! But um...” with a blush herself, Millie said with a smile, “G-go ahead and let your penis just... squirt inside me again, as much as you need to.” They continued like that, with Millie cooing happily at Ozy when his penis emitted another little burst of semen. And of course Ozy’s father came to check on them. “W-we saw a movie,” Millie said quickly the moment Lewellyn the dragon strode into Ozy’s room. “It didn’t um...” “Oh my, I hadn’t realized you two were getting to be that age,” Ozy’s adopted father said in concern. “You do know that sex makes babies, right?” he asked the conjoined children. “Uh huh,” Millie said, with her ears down, “It started feeling too good to stop, sorry.” “It’s my fault,” Ozy said disconsolately, tugging at the knotted penis within Millie’s tight vulva, “I just wouldn’t stop, and... I wanted to put a baby in her.” “It’s perfectly natural to lose control when you’re in the middle of the act,” Lewellyn said frankly, “If you saw dragon mating rituals you might be shocked how ferocious they get, but unfortunately all non-dragons aren’t allowed to witness it, ever since the bacon and eggs incident of 400BC.” “I think we’ll pass,” Ozy said diplomatically. He grunted then, and another pulse of semen entered Millie’s vagina. “I-it keeps squirting a little,” he said to his father with a blush. “Millie said she likes it.” “I honestly haven’t researched into wolf mating behavior very much at all,” Lewellyn admitted sheepishly, “How long have you two been knotted?” “A... while?” Ozy said vaguely, a little miffed that he couldn’t stand up on twos, but curiously calm and strangely satisfied at the feel of his penis back there, thick and locked into the vagina of his best friend. “Well, don’t try to pull apart right away,” the dragon said, “I need to go fetch a bucket.” “A bucket?” Ozy asked blankly. “Well yes, hmm,” Lewellyn said, leaning down to peer at their sexual joining. Ozy and Millie pulled far apart as they were able so he could see in between them, but were quickly butt to butt, as he said, “As I suspected, wolves have a knot, to seal in the semen and ensure the female (that’s you, Millie) is impregnated.” “Heh heh yeah I... still feel all that semen inside me,” Millie said sheepishly, “Guess it’s probably making me a mommy by now.” She oohed as another little squirt of semen entered her, practically purring when she said, “And Ozy keeps giving me more...” “Thus the bucket,” Lewellyn said definitively. “You’re going to have a lot of semen in you young lady, and I’ll not having you making a mess of the floor. So try not to separate, and I’ll be right back.” The silence persisted as the dragon left, yet not an anxious silence, because both Ozy and Millie felt calmed by the presence of one in the other. Millie gave a little squeak as Ozy ejaculated another little burst of semen into her, then giggled, and said indulgently, “I’ve got so much semen in me I’d make a mess all over the floor.” “...I hope you’re not thinking what you’re thinking,” Ozy said cagily. “...no, I guess not,” Millie admitted, smooshing her furry fucked pregnant butt up against his, “I wanna keep your semen inside me as long as possible. Making me all pregnant in there.” “I do—” Ozy cut off, saying tensely, “Hold on, I have to...” “Go ahead,” Millie said with a smile. “Nnh!” “Ooh, that was a good one,” Millie replied, as the squirt from Ozy’s penis spread out through the seed within her. “Y-yeah,” he said, relieved. “This’s even better than the mating,” Millie said almost in surprise, “It should be totally boring, but I just wanna stand her on all fours just... doing this with you.” “It is pretty amazing,” Ozy admitted. “Well, here’s the bucket,” Lewellyn said, sticking his head in the room again, with a bucket in his clawed hand. “You two lovebirds having fun?” “Yeah!” the knotted pair said, looking up to him with delighted eyes. “When his knot softens, hold your vagina over this, until his seed stops dripping out of you,” Lewellyn explained handily, “It’ll still be quite messy, but that should catch most of it.” “Y-yes sir,” Millie said, hoping she could remember all that. All she really could think about was the strange pleasure of standing here being knotted. “I’ll leave you younglings to enjoy the afterglow,” Lewellyn said, heading for the door, “I’ll check on you if you’re not separated and all cleaned up by supper, but until then, congratulations on your first mating, and possibly your first child. He rubbed both their heads, and headed off, and Millie sighed happily, saying in a dreamy voice, “I love this...” “I do too,” Ozy said, pushing his butt against hers warmly. “Waiting for you to give a little squirt,” she said more teasingly, squirming around his penis in there. The two gazed at each other in yearning patience, until Ozy’s eyes lost focus, and Millie said eagerly, “Oh, you’re doing it!” and he squirted. They gazed at each other again, even more affectionately, until Ozy started to lose it again, and Millie smiled, saying, “That’s it, Ozy. Squirt it into me, make me as pregnant as you can.” He squirted, and she mmmd in delight. “Squirt as much as you want in there,” she repeated in serene delight, “I’ll keep it safe inside me... it’s our baby inside my belly, and I’ll keep it safe because I’m a mommy now. So squirt in me as much as you like.” “You know when my knot shrinks, you won’t be able to—” “Yeah yeah, you know what I mean.”
