"Sarah, how did you manage to explore the cave for so long? Did you have a spare battery for your flashlight to last that long?" Julia asked
"In fact I barely even used my flashlight, I met someone very interesting down there." Sarah said
"Met someone interest....ooooohhhh...What is this, what is happening to me? Aaahhhh..." Helen said when just out of nowhere she got very horny and came extremely fast. Same with Julia and Frank.
"Lilith, that's your thing, isn't it?" Sarah asked looking at the deity leaning on the edge of the boat.
"It was just my way of saying hello to your friends." Lilith said, having finally been noticed by others
"Who are you?" Frank asked as he and the girls recovered from their last orgasm.
Lilith dove into the water and seconds later she jumped into the boat, landing on her seat next to Sarah, and said "I am Lilith. Sarah here found me trapped down there and freed me."
The trio was surprised seeing the girl naked, especially with the big dick in her crotch and her fish tail.
"I can't believe what I'm seeing, a real mermaid." Julia said
"You won't believe it, but she's not a mermaid. In reality she is a deity." Sarah said
"I only assumed the form of a mermaid because it's easier to swim like that." Lilith said, her mermaid tail reverting to human legs.
"No way. A deity? But what would a deity be doing trapped in an underwater cave?" Helen said
"It was sealed inside a chest and I broke the seal." Sarah said
"You shouldn't have done this Sarah. If she has been sealed it is because she is dangerous." Frank said
"No need to be afraid of me. Other deities sealed me a long time ago because they thought I was too perverted, all I want is for everyone to feel good. Look at Sarah, she loved the gift I gave her." Lilith said
"What gift are you talking about?" Julia asked
"She is talking about this." Sarah said, baring her legs so that the bulge formed by her cock in her diving hoarse was visible enough to leave no doubt about what was there.
"I can not believe this. Did Lilith give you a dick?" Helen asked Sarah, who just nodded.
"I can change everything and everyone as I want, giving a dick to a girl is a simple task for me." Lilith said
"Tell me something Sarah, what's it like to have a dick? I wanted to know from a girl's point of view." Julia said
"Well, at first I felt strange, but after I came I didn't want to go back to normal anymore." Sarah said
"You will know better if you try it yourself." Lilith said
Julia then felt her bathing suit tighten and looked to see a bulge form due to a dick growing between her legs. Her new member grew to 15 inches, passing between her breasts and with the tip sticking out of the neckline of her swimsuit. Soon afterward a ballsack grew between her legs with coconut-sized testicles. She noticed that her dick had a different shape than normal.
"What do you think? I gave you a dick in the shape of a horse dick, I believe you will like it better that way." Lilith said
"I... I'm still finding it hard to believe. I really have a dick now....aahhhh" Julia said, but she immediately came when touching her new member through her swimsuit, as it was much more sensitive than she expected.
