Kylie Keller, a twelve year old black-footed ferret girl, woke up along on a warm late spring morning. As she stirred she noticed something different about her. The tomboy, wearing a white sport t-shirt and red shorts, wriggled a bit in her bed. There is a certain warmth in her loins, not like anything she had felt before. In her small town there aren't a lot of kids her age to interact with, and almost nobody talks about the changes a girl goes through to become a woman. She lied on the bed half asleep while something unusual had crossed her mind, at least to her. It seemed weird to her, but had the notion that it would be a good idea to be with the boys on her soccer team. While the middle school soccer team was co-ed, they were normally all boys. This didn't bother her before as she had no problem keeping up with them. On this day in the middle of spring break there was a knock on her door. That's when she remembered that she and her next-door neighbor, Neil, were going to go fishing together. She bounded out of her bed and down the stairs to open up the door. Neil was a mink, standing just as tall as Kylie with a couple of fishing poles in hand. "Are you ready?" He asks, to which Kylie nods in the way that mustelids can, and she locks up her home before scurrying into the woods with him. The two had met when she moved in a few years prior. Her father had passed away and her mother had to move to find work. The two became fast friends, and even faster teammates. There was just something that they had not anticipated was for nature to force them even closer together than they ever imagined. As they got to the edge of the fishing pond they noticed that it was really quiet. "Nobody else is here Kylie," Neil mused. "I think we got the whole pond to ourselves!" He starts to set up the rods with that he though was appropriate bait for the fish in the pond. Two hours pass with the two of them just sitting on the shoreline, watching a pair of rods that are not budging. "I don't think we're getting any bites today Neil," Kylie said with a sigh. "We had such a good run the other day.. do you think we got them all?" She stood up and walked over to the rods, as though to inspect them. As she does she bent over and raised her tail without even thinking about it. Neil responded, "I wouldn't think so." He says, "It's probably just an off day." He sees his friend's rear end. They're covered in shorts, but the way that she's positioned and with her tail up has his mind racing... but he can't put his finger on just what. Kylie pondered for a moment before she proposes, "Perhaps then we can swim. I mean, might as well make the most of it, right?" "But we don't have our swimsuits Kylie. Are you thinking about swimming in those clothes or... going in naked?" He asked, somewhat confused. Kylie stated, "Well, we've seen each other naked before, right? When we played doctor in third grade?" She asked, "It shouldn't be any different." She says... though when she pulled off her shirt it was obvious that there was already something different. Neil pulled his own shirt off and then gazes at Kylie's chest. Her nipples where rather puffy, like her breasts were trying to grow in. Kylie was not oblivious to his sudden attention though. "Oooh!" She says, using her hands to cover her chest, "Maybe... there is something different," She said in a huff. Neil shook his head as though he tried to get that image out of his mind. "Oooh! Umm... I didn't mean to stare Ky. I mean... they look good." He stammered, "I'm not going to get out of this without looking like a perv am I?" He asked. He reached down at the waistband of his jeans when he realized something, he was sporting a huge erection. It was... probably harder than he had ever felt it before. He noticed a funny feeling recently when he saw some bikini-clad girls in videos but it seemed much more exaggerated when there is a half-naked girl right in front of him. The ferret unceremoniously tugged her shorts down along with her panties, stepping out of them and standing straight up in front of her mink friend. That's when she noticed the boy's rock hard erection in front of her. "That.. that doesn't hurt, does it?" She asked, "And.. why is it doing that?" Neil looked down nervously, even giving a little blush in his ears, "Umm.. It started getting hard recently.. it doesn't hurt just... well, it's really sensitive..." He says. He gulped in nervousness, unsure of how things would develop. Kylie reached a hand over to start stroking at the boy's member. It was thin, as mustelid members tend to be, yet smoooth and warm to the touch. Kylie's fingers started to stroke along the underside, which caused Neil to gasp. Kylie to paused for a moment and asked, "Did that hurt?" "No," he said, "It was just.. unexpected..." The boy tentatively moved his hand over to Kyle's thighs, which spread for him, thus she invited him along further as he touched at her folds. Her breathing quickened at the touch, the ferret's heart increased it's pace as she felt the electrifying feel. She then moved her hips just slightly, which made her folds glide along his fingers. "That.. feels good to me..." She sais shakily. A light went off in Neil's head. "Why don't you lie down Ky.. I.. I think I know how to make it better..." he told her. She gave a light nod and settled on top of the clothes. It wasn't the most comfortable, but she looked up to him with a look of curiosity. With her legs slightly spread a certain spicy scent filled the nearby air... later he would recall and realize the scent of her first heat just starting up. Neil lowerd himself over Kylie. He supported himself with his hands as he slid into place, his firm member pressing and teasing at Kylie's puffy mound. Little did they know that this was just the start of it. For a few minutes they laid like this... just savoring the feeling of their near coitus state. His tip started to slip beneath her folds, finding the entrance to her never before breached passage. With yet another motion that member starts to slip in. Something was different for sure, as he felt her velvety passage envelop his member, no barriers to bar his entry as her hymen had torn during a soccer game some time before. Kylie felt it encroaching as she gazed up to him in disbelief of what was happening. Then Neil started to pull back.. just to push forward again, feeling nature guide his motions. With the pair all caught up in pleasure that they would not soon forget. There were no words as it seemed that they were out of their minds. It didn't last long though as Neil started to grunt hard. He gave a firm last thrust as his young sack drew up against him, delivering its payload of potent seed into his best friend. She felt the heat spread within her as it quenched a heat that she did not know started within her. She held onto him close.. a part of her wanting to feel more, but she also did not want to push him either. A few minutes passed before they caught their breath and their heads came out of the sky. "Mmm... so much for skinny dipping, huh?" Neil asked "And.. what did we do?" Kylie said, "I don't know... but it felt wonderful. I want to do it again but..." She looked down to see that Neil's member had withdrawn, "You're not hard anymore... and what is the white stuff? Did you do that?" Neil took a look down as well, "I don't know.. it felt like something came out, kind like when I pee but it's different." He said. "I think we need to pack up and head back before your mom gets home." The pair got redressed, but when he realized that the drippings were on his shirt he decided to carry it instead. The pair made their way home uneventfully and went on their seperate ways. They would have plenty of time to figure out what happened. After a couple of days a zygote entered Kylie's womb, starting the tomboy on the way to an early motherhood.
