It was a cold winter day in the forest where Nel and Ereyel lived. The tree that contained their house had begun to collect the snow that had just started falling. Ereyel sat at the table and looked out the window. She hoped Wizlant would make it back before the snow got too deep. He wasn't the best at flying, so he would probably have to walk in this weather. She shivered a bit. The tree was mostly warm, thanks to some magical heating devices that Nel had developed, but it still had a chill in the air. Not that it showed with Nel, she was still bounding around naked as always. Speaking of Nel, Ereyel noticed that she had been locked away in her study all day. She hoped for the best, but expected that it would end in one of her "experiments".
 
With that thought, she felt something soft land on her head. Two somethings to be precise, and looking up, her suspicions were made true. Nel's breasts were planted firmly on top of her head. "Nel... What are you doing?" The elf asked with a hint of frustration in her voice.
 
"Nel made something!" The harpy gleefully stated, lifting away from the elf and sitting at the other side of the table. "Eri should see! It'll be good!" Somehow, Ereyel had her doubts, but she calmly nodded. It was then that she noticed something a bit different about the eagerly bouncing harpy in front of her. It was her breasts. They looked bigger, and they sat heavily on her chest. Her hidden nipples were lightly tinted with moisture. Nel had always naturally lactated, but Ereyel had never seen her look this full. She quickly realized that this is probably what the harpy wanted her to see.
 
"Um..." She tried to think of the best way to word her question. She gave up and went with the blunt approach. "Did you... fill your breasts up or something?" Nel giggled as she happily nodded.
 
"Nel made special milk! Eri needs to try it! It's super tasty~" Nel's happy singsong voice made it hard to ever tell her no about anything. Ereyel simply sighed and got up to get a glass. It had always been easier to just give in, since Nel would pester her until she did. Besides, it was just milk. And her milk had always been good.
 
Once the elf returned with the glass, Nel looked at her silently. "What? Did you change your mind or something?" The elf asked. "I'm kinda thirsty anyway, so let's go ahead and do this."
 
"Eri shouldn't use a glass..." The harpy said softly. Ereyel stared at her for a moment. "Nel's milk um... Milk loses special unless Eri drinks directly!" The harpy looked slightly flustered. She was obviously hiding something about all this. Ereyel continued to stare at her. The harpy was a terrible liar, but she couldn't figure out what would be so bad about milk. Nel continued her protests against the glass while the elf weighed her options.
 
Suddenly, the door flew open, letting in a cold burst of air that startled the both of them. "O-oh, your bother must be back!" Ereyel took the opportunity and broke off from the conversation to check the door. However, what stepped through the door was not Wizlant, but instead a red-haired beastkin.
 
"Hey guys. It's cold out there, so I'm gonna crash here for a while." Kiarrah brushed some snow off her fur as she stepped inside. Of course she was cold, she was still wearing her usual skimpy outfit. Ereyel sighed yet again and greeted her. Arguing with her was usually even less successful than arguing with Nel. The two of them sat back down at the table with Nel, who happily greeted the beastkin. After a moment, she looked like she was struck with an idea.
 
"Oh! Kia should have some milk! Nel made it special!" Nel cheerfully bounced as she offered to Kiarrah. "Milk? Yes." There was zero hesitation from the beastkin, at least until she thought about it for a moment. "Wait. Special milk? Guess that's why your boobs look like that. Hmm..." She thought for a few seconds. "Yeah sure. I'm not gonna turn down free milk."
 
The harpy happily cheered, but then remembered to tell her the next part. "Oh but... Kia can't use glass! Kia has to drink directly from Nel!" She looked over at Ereyel, who was trying to just stay unnoticed. "Eri must drink too! Both! If Eri doesn't drink, then Kia can't drink!" Ereyel winced as she could feel Kiarrah staring daggers into her. There weren't many things that would keep this beastkin from some good milk, and an unwilling elf certainly wasn't one of them.
 
"Alright alright, fine." Ereyel threw her hands up in the air as she gave up. "I'll... I'll do it. Just... don't make this weird, okay?" The harpy cheerfully nodded, barely able to contain her excitement. Kiarrah patted the elf on the back. "I appreciate your sacrifice." Ereyel glared back at her for that comment.
 
The two of them got in position, each sitting on one of Nel's legs. She was taller than both, and sitting in her lap put their heads perfectly at level with her nipples. Or perhaps she used a little size magic to make it perfect. With that harpy, you can never really tell. There was little hesitation from the beastkin. She latched onto Nel's breast and started to greedily drink. Nel gasped at the sudden move and looked over at Ereyel, nudging her on. As Nel's arousal grew, he nipple slowly popped out, growing puffy, practically begging for the elf to drink. Ereyel looked over at Kiarrah one last time, who was giving a thumbs up approvingly. Well, at least it apparently tasted good. The elf slowly opened her mouth and placed it on Nel's breast. After a few testing licks, she started to lightly suckle. Nel let out a light moan from the pleasure and brushed Ereyel's hair lovingly.
 
The milk was good. Very good. She couldn't really explain it, but it was so much better than Nel's normal milk. Perhaps it had something to do with drinking directly from her, as this was first time this had ever happened. Ereyel threw that thought out of her head, assuring herself it was just one of her magical experiments. She must have just improved the taste somehow. She slowly started to drink more, enjoying the taste more with every gulp. Looking over at Kiarrah, it was obvious she thought the same. Her face was practically buried in the flesh she was drinking from. She could see the beastkin gulping down huge quantities of milk as greedily as she could. Nel's milk output must have been enhanced as well, as there was no way she would be able to keep up with Kiarrah normally. The beastkin's belly started to slightly bulge as she continued to drink like a woman possessed. Actually, looking at her, that's exactly what it looked like. Her eyes were glazed over and she just keep getting more and more greedy with every gulp.
 
It was then that Ereyel noticed that she was doing the same. Milky cream was flowing into her mouth as fast as she could swallow. She couldn't control it at all. It just tasted so good. She looked up at Nel, watching her gasp and moan, hugging the two of them closer, pushing them to drink more. Ereyel's stomach was overly full with milk, yet she still kept drinking. Her body was falling into pleasure and her mind had nearly shut down. Looking back over at Kiarrah she was suddenly pulled out of her trance.
 
The beastkin had pushed herself so greedily that her head had been engulfed by Nel's engorged nipples. And ever so slowly, she was being sucked inside. The milk was working as a lubrication, easing her in. There was no resistance from her, not that that was unusual for the lazy beastkin, but Ereyel could tell it was something different. Feeling herself push forward, she knew exactly what it was. The milk was clouding their minds, making them want more. She couldn't control her body as she could feel the nipple expand to allow her head into the milky interior of Nel's waiting breast. It took every ounce of her willpower to keep her thoughts in check and try to struggle against her body. It was no use though, as her head was quickly enveloped and the rest of her soon to follow.
 
From inside, she could hear Nel's moans grow stronger and louder. There was no air inside, there was nothing but that wonderful milk. Ereyel's body did the only thing it could think of, and that was drink as much as possible. Her mind was cascading into euphoria as more and more of the milk entered her stomach and as more and more of her body was sucked inside. Waist-deep into the milky haven, Ereyel pulled her arms inside and started trying to use them to push more of the sweet cream into her waiting mouth. Everything in her mind was trying to fight, but it was a battle it was quickly losing. Nel's magical milk had reduced both Ereyel and Kiarrah, who was now fully lost in her breast, to nothing but greedy drinking messes. As the elf's feet at last slid in, the final strands of her willpower finally broke.
 
With both of the girls trapped within her massive breasts, Nel started to massage them, moaning and gasping the whole way. Inside, Ereyel continued to drink without a care in the world, she couldn't even notice when her hands and feet began to soften and melt into more milk. Her stomach, sloshing with cream, had grown to the size of her head. Her body was losing its form with every drink she took, but she didn't care. All she could care about was the taste. Her consciousness began to fade as her body lost form, expanding out to become more of Nel's milk, adding more to her bust. At long last, there was nothing left but the sloshing sound of the milk that used to be her friends within Nel's breasts.
 
The pressure had already built up and she began to leak milk on the floor. Pulling her mind from the pleasure, Nel quickly got some buckets together to gather the cream. She carefully made sure to keep the two milks separate, making one set of buckets for Ereyel, and the other for Kiarrah. After several long, wonderful minutes, her breasts had shrunk down to about half their size. They were still greatly larger than Nel's normal size, but at least more manageable. She filled about a dozen buckets from each breast and decided that was more than enough to save. She lifted the breast that had contained Kiarrah to her lips and started to drink from herself. The taste was so much more different than before. No longer hypnotizing, but now more of a slow, heavy cream that just made you want to sleep. It was wonderfully comforting and took all that Nel had to not fall asleep. Letting her mouth release the nipple with a pop, she moved onward to the other breast, the one she was really looking forward to.
 
She wanted to know what sort of milk her dear elf friend would make. She starting sucking slowly at first, wanting to appreciate the taste. It was different as well. But unlike Kiarrah's, it was light, almost silky. And the sweetness was amazing. It was almost like liquid candy. She was fairly certain milk shouldn't taste like candy, but she didn't care. It was everything she had hoped it would be and she kept drinking, alternating between the two to keep her balanced. After nearly ten minutes, her breasts were nearly back to their normal size. However, her belly had grown quite a bit. She sat back in her chair and let out a deep sigh. Looking around, she had enough milk to cover them for months, though she only hoped the magic she added would keep it fresh for that long. Realizing she needed to get back to work, she used some magic on her sloshing stomach to speed up the digestion. Her belly slowly shrunk down to a more manageable size before she hopped up and started carrying the buckets of milk to her study. Just as she was about to get back to work testing it all, she heard the door open.
 
"Nel? Ereyel? I'm back!" The voice of Wizlant came from the front room. "Um... Why is the floor so wet..? Is that milk..? I guess it's a good thing I bought some more."
 
Nel bounced out her study to meet him holding a bottle of milk. "Wiz! Wiz! Nel has something for you~"
