Scootaloo the Bitch and Winona the Stud
Scootaloo looked at Winona, a blush on her face. The dog didn't look much different than before, save for the bitch was now a male. Scootaloo gulped hard as mix of nervousness and arousal coursed through her little pegasus body.
“I hope Applebloom doesn't notice I swiped a few of her potions, boy,” Scootaloo spoke to Winona, who was still trying to get used to the changes made from the potions Scootaloo had let him drink. They had made him feel a bit funny, and he was quickly approaching the filly. Something about her had caught his attention, each step toward her caused his cock to harden more and slide further from its sheath.
Scootaloo was still nervous about what she was about to do, and the fact that she 'borrowed' things from a friend. Those thoughts were quickly pushed to the back of her mind when Winona pounced on her, giving loving licks to her face.
“Hahahaha Winona! You knew I was nervous, huh?” she asked, each lick calming her down. Well, at least calming her nervousness. She was getting a little aroused from those licks, her wings extending out. With his heightened senses, Winona was able to tell that the filly smelt good... real good, like a bitch in heat. Each heartbeat caused his cock to throb as he watched Scootaloo stand up, turn around, lift her tail, and squat a little.
“Well, come on boy, you want some fun?” Scootaloo asked, not sure how she went about seducing a dog. Though it seemed she didn't need much help. She let out a startled yelp when she felt a cold nose press against her slightly damp slit, followed by a warm tongue lapping at the tasty treat. The warm tongue caused her to moan and whimper loudly, as well as push back against it. Every lap dragged that wide, warm, wet tongue along her little clit, sending electric shivers through her entire body.
Scootaloo had an idea before she had started things in motion that she would be the one in control of the situation. But when animal instincts take over, things tended to get out of hoof. The wide tongue continued to lap along her slit and a bit higher. Winona enjoyed the tastes immensely. Scootaloo was already having more fun than she had originally planned. She turned to look behind her and saw Winona, his cock hard and throbbing.
“You want more boy? You wanna mount me?”
Winona paused his licking, much to Scootaloo's disappointment. She was about to complain before she felt paws on her rump. Scootaloo looked back and gave Winona a huge grin.
"Guess you aren't much into foreplay, huh Winona?"
Winona responded with an eager bark, awkwardly trying to get into position. Scootaloo realized she wasn't in the right position, so she squatted down some more. Winona began to hump now that he was in the right position, each one pushing his hard cock against her holes, first her pussy, then her plot hole.
"C-careful, Winona," said Scootaloo, her voice slightly ragged from breathing hard. "I don't want to do anal my first time with you."
Winona responded with a louder bark, more aggressive this time. His humping pushed his cock tip up against Scootaloo's warm, dripping pussy. When he felt the warmth, Winona gave a hard thrust and almost buried his bone fully. Scootaloo's wings flared out completely, the little pegasus letting out a loud cry of pleasure from the rough intrusion. The tip bumped against something deep inside of her and she eeped, blushing very deep.
“C-come on, Winona. You want my virginity, don't you?”
Winona hunched over a bit and gave another hard thrust, sinking more of his cock into the filly's passage. Scootaloo scrunched up her face and let out a very loud yipe sound as the tip broke past her hymen. Through tears streaming from her eyes, a wide smile grew on her face. It was at that time that she realized, she wasn't as in charge as she thought.
Winona began to act according to his instincts, leaning down and biting onto the back of Scootaloo's neck. He wasn't trying to hurt her, but assert his dominance over her. His thrusts into her wet, tight, filly cunt became rougher with each passing second, the dog not at all concerned with Scootaloo's pleasure or pain. To him, she was just another bitch to rut, tie, and impregnate.
Scootaloo had planned for many things, but was not aware of a very important part of a dog's anatomy, which she was about to learn about first hoof. The cock shoved in harder and deeper when something rather large started to press against her little entrance.
“Y-you're getting bigger!? Ok, you can slow down, and not so rough Winona!” she complained through loud moans and grunts. The grunts were getting louder as the knot started to inflate, the dog let out a howl of pleasure when it slipped between Scootaloo's lips. Scootaloo was surprised to find Winona actually listened to her, her breathing became a little more relaxed. Once she had caught her breath, she gave a nod to Winona.
“Alright, I've rested enough, you can start again.”
But Winona didn't start thrusting again. In fact, he let go of Scootaloo's neck and started to turn around, giving a couple of tugs against the knot inside of her as he turned the tie. Scootaloo let out a whine mixed with a moan at the feeling of the knot rubbing her sensitive passage. But when no other movement after Winona and Scootaloo were butt to butt, Scootaloo turned her head and glared at Winona.
“Hey! Dumb dog! I didn't even get off! What are you doing?”
“Huh. Never thought I'd see Winona tied with a pony... considering she's a GIRL dog!”
Scootaloo recognized the voice and turned her head to see Applebloom standing there in the barn entrance, a smug look on her face. Scootaloo opened her mouth to say something, but Applebloom shoved a hoof against her mouth, silencing her.
“You REALLY think I wouldn't notice something missing from my room? And you didn't really think too far ahead. Dogs don't last long, they don't care if you get off or not, and they knot their bitch when they finish."
Applebloom blushed some and squirmed, obvious that she at least had some experience with mating dogs... possibly first-hoof.
"You'll be stuck like that for a while," Applebloom continued. "Oh, and did you swipe multiple potions for your little bit of fun?” Applebloom asked, though it was a rhetorical question. She knew exactly what potions were taken.
“Well, you got the gender shifter, a production inducer and a fertility increaser. Oh, and since she, well he now, lapped at your slit and gulped down your juices, you two can cross produce. Enjoy your puppies!”
Scootaloo's face fell and she pinned her ears back. She couldn't see it or feel it, but the dog sperm was swimming their way toward a few eggs in Scootaloo's womb, at least 4 of them getting impregnated.
“You can't tell anyone!”
“In a few months, I don't think I'll have to.”
A few months passed by as the tell tale signs of pregnancy became quite apparent. Scootaloo's belly was quite rounded out and her little breasts were full of milk to the point a few drops of milk would drip out of her nipples. Though she got the odd stare from some of ponies, most were quite supportive of her condition. Of course, until the birth, nopony besides Scootaloo and Applebloom knew the truth about the life Scootaloo was carrying.
More time passed and Scootaloo's pregnancy progressed without a single problem. Eventually the time came for her to birth her foals. Applebloom was the one that rushed Scootaloo back to where the whole incident started. It took a few hours but eventually Scootaloo was the mother to 4 healthy dog/pegasus hybrids. The dog pegasi flew out of the barn, barking loudly.
“Congrats, Scoots,” said Applebloom. “You're a mom.”
