Mary woke up to a feeling of tightness in her breasts. The events of the previous day came back to her and she rushed to the bathroom and fished her breasts out of her top. She started milking one of them over the sink and sighed. The other sat there enticingly and she lifted it up with her other hand and placed her nipple between her lips. The creamy deliciousness washed over her tongue and she quivered at the feeling. As the pressure decreased her pleasure was increasing and she soon found herself laying on the bathroom floor, her breasts empty and her panting from her orgasm. She wondered if she'd be able to skip breakfast because because she felt full of her own milk.
It was an excuse, but it was also one that she was willing to take as she desperately wanted to get back to the ocean. She got to the portal and sat on the edge. After taking a deep breath she jumped in and landed in the cave. She was just about to jump into the ocean when a form emerged from the water. It was a mermaid like her, almost. Instead of a fish's tail this mermaid had the tail of a dolphin. From the waist up she was a beautiful Asian woman with flowing blue hair. Her body looked perfect and her breasts contested Mary's own in terms of size. Instead of seashells she had a pair of starfish clinging to them. She smiled at Mary. "I thought I smelled someone new here yesterday. Hello, I'm Hitomi." She had a slight accent and actually bowed a bit as she introduced herself.
"...Hi," Mary was a bit taken aback at the woman's sudden appearance. "I'm Mary."
Hitomi smiled. "Let me guess," she said, "you received a case of vials in the mail?"
"Yes!" Mary said and she stepped forwards excitedly. "Do you know anything about them?"
"Only that I received a similar case three months ago. Currently I know of three other women that have also been changed by them, though those are only the ones that have access to this place. There may be many more."
"Other women? You mean other mermaids?" Mary felt excited and jumped into the water. She felt her clothes vanish and then felt the change overcome her. She swished her silvery tail back and forth while Hitomi looked at her in shock.
"My... You're a most traditional looking mermaid aren't you?"
"Are the others not?" Mary said with a bit of concern.
"No, I am the closest of all the others. You will see them for yourself I'm sure."
Mary looked over Hitomi and thought for a moment. "Ok so, I don't know if this is rude or anything but did the vial change things besides giving you the tail?"
"Yes," Hitomi said while looking downwards. "Japanese women are not exactly known for these," she gently hefted her breasts to emphasize her point. "And as you might guess I was not born with blue hair."
"Yeah it did a number on me too..." Mary looked herself over. "Did it make you... Do you lactate now?"
Hitomi's eyes went wide. "No! None of the others either. The vials said that this may be a side effect but I did not think that..." She blushed a bit. "I am sorry. It's not like you did anything wrong."
"No it's fine," said Mary, "to tell you the truth it's a bit embarrassing."
"I can imagine," Hitomi tried not to but Mary could tell that she was glancing at Mary's breasts every now and then. Unless Mary was mistaken she thought that the Japanese girl might be more interested that she was letting on.
