Karima's orgasm started fading. Lying on the floor, still blissful and happy she looked at Mary. "So you're a mermaid? For how long? I have to admit, that you taste wonderfully" said Karima and licked her lips. "Oh, Karima. I became a mermaid a while ago. But look at you, you've just became one too!" Mary crawled closer to her roommate and looked deep in her eyes. "And I have to admit, that the nature gifted you more generously than me"- Mary poked Karima's lover pair of breasts. All four of them were still producing milk. Karima looked down. Her once beautiful and thin legs were replaced by black and white tail, wrapped by silver tail of Mary. At first she was very shocked, but after the while she found out that she can move her new appendage up and down, but obviously it wasn't meant for her to use it on the ground. Then she looked at her abdomen, and she realised that her sharp muscles are gone, replaced by small doses of fat. But that wasn't an end of her shock. She noticed her four massive tits constantly producing milk and she felt a mix of excitement and arousal that she started producing this delicious stuff too.
Karima gave Mary such a deep and long kiss. She was the one that let her taste her mermaid nectar first, and she was the one who made her mermaid as well. Mary hugged Karima tighter, feeling her four nipples sticking harder into her, wrapping around and rubbing her tail. Instead of roommates they became members of one sea family made by this act of lust and magic. Shortly after, Mary found out that Karima still had her vagina in similar place that her human one would be.
But then Karima stopped kissing Mary and leaned to one of her newly formed tits. She started sucking it deeply. Her milk was different in taste than Mary's, but still the same, top quality- the sweetest of the sweetest substances she ever drank. Without stopping, she grabbed Mary's head and pressed it to her another tit. She felt double sensation that was building another orgasm in her, yet to think that she still had another two "free" nipples... They finished drinking one tit each and started drinking second ones. Soon Karima couldn't stand it. She arched back, screamed in pleasure and leaking another substance, but this time from her mermaid vagina.
Mary, still catching breath after another mermaid pleasure session looked at Karima satisfied and proud. "You don't belong here. I believe I know where you can feel like home, and where we both can be... naughtier" Mary bite her lip as she finished her sentence. "Are there other mermaids?" asked Karima, "not yet" responded Mary and smiled. Then she wished to be human again and stood in front of Karima in her naked human form. Her indian friend was gazing at her in awe.
"Let me take you there. Something tells me, that you can't change back like me, so I would need your cooperation". She picked up Karima's upper half and took her to Mary's room, dragging Karima's tail behind her. While being dragged Karima was looking at her mermaid tail and pinching her four nipples. She was constantly producing milk, so she felt new batch of substance sloshing in her tits. Finally they reached to the room and Mary took Karima through the portal. Karima dived and submerged in the pool revealing herself in wet and happy mercow form.
