Sarah Blue was diving during her summer vacation trip with some friends, they had split up in an attempt to find something interesting. During her underwater tour she saw a crack between some rocks that she could pass through, curious, she went in to see what she found. After passing through the crevice she found herself inside an underwater cave, the tunnels had enough space for her to swim freely. Later, as she went a little deeper, Sarah found an air pocket where she could pull out her equipment to explore. She turned on her flashlight and walked along the linear path for approximately 100 meters until she found a chest on some rocks.
"How interesting to find a chest in such a place, is it possible that I found a pirate treasure?" Sarah said approaching her find, examining it and seeing that it was locked with an extremely worn padlock.
Curiosity got louder and Sarah decided to try to open the trunk to see what was inside. She placed the flashlight next to it, then tried to force the lock with her hands, which due to the wear and tear of time had made it fragile and she broke it without much difficulty. With the chest unlocked, she opened it and immediately rose pink smoke that filled the cave.
At first the girl started coughing from the smoke, but soon after she started to feel very horny and, before she could do anything, Sarah had a very intense orgasm. When her orgasm ended she fell back on the rocky floor, but she remained conscious. She then noticed two very strange things, the first being that the smoke was gathering all in one place and the cave was fully lit, making the use of a flashlight unnecessary.
Sarah got up and saw that the trunk was empty, so she turned her attention to where the pink smoke was gathering and realized that it was taking human form.
"What smoke is this? Is this what made me come so hard without doing anything at all?" Sarah questioned as she watched the shape of the smoke becoming more and more like a woman. Sarah questioned as she watched the smoke's shape grow more and more like a woman's until, gathering all in one place, it solidified into a real girl. The girl had long hair in black, blonde and red parts, she had heterochromia because her left eye was brown while her right eye was blue. She had huge breasts, clearly H-cups at the very least, however what caught her most attention was a one-foot cock that was hard between her legs.
"Finally, after so long I'm finally free again." the girl who had been formed by the smoke, which was floating in the air, said
"Who are you? What just happened here?" Sarah asked
"Oh! Sorry for my rudeness, especially after you released me. My name is Lilith and I am a deity." the floating girl said
"A deity? But..." Sarah said but was interrupted.
"I know, you never believed that deities really existed. You can believe that I am very real. I've been sealed off for billions of years and you finally showed up to set me free. I am not ungrateful, you will be very well rewarded." Lilith said, slowly stroking her cock from which dripped precum.
Sarah, realizing the intention of the deity, waved her hands in front of her saying "I don't need it and even if I did, your cock is too big for me." trying to ignore that she felt an attraction to the futa deity.
"No need to be humble no Sarah, I know you want to." Lilith said
"No, I can't... Wait a minute, how do you know my name?" Sarah said
"I already said that I am a deity. I know everything about you, including all your secrets. If you want an example I can mention the collection of dildos you have hidden in the false bottom of your wardrobe, they are all large sizes. I know you are bisexual and that you like big dicks a lot, the bigger the better." Lilith said
Sarah blushed, not only at what the deity had said about her, but also at her getting everything right about her.
"Did you understand what I said. Now let's get down to business, it's been an eternity since I've had sex with anyone. Don't worry, you'll love it. My power made you come that way just to set me free, I promise I'll make you feel a lot better than that" Lilith said
Sarah didn't feel right doing this sort of thing with someone she'd just met, even if that someone was a deity, but she'd never felt this turned on before. She believed that she was being affected by Lilith's power, and with that she couldn't hold herself mainly with the deity's hard cock right in front of her, she really wanted to have that cock inside her.
Sarah took off her wetsuit and lay down on the rocky ground offering herself to the deity, who didn't take long to stick her cock in the girl's pussy. She felt so horny that her whole body seemed to be more sensitive to any stimulus, but she felt strange to feel that she reached the limit and would come, but still she did not come.
"What is happening to me Lilith? Why can't I come?" Sarah asked
"Sorry but I don't want you to orgasm so fast, so I synchronized with your body so we both could come together." Lilith said. She continued to fuck the diver girl, but stopped a little and pointed a finger at the crotch. A hard cock grew, reaching a foot long, and a large pair of balls to go with it.
"Did you make this cock grow on me? I don't want this, please get me back to normal." Sarah said.
"Don't be so hasty, we're having fun. Once we're done and you've actually experienced my little gift you can decide if you want to get back to normal." Lilith said going back to fucking Sarah that, in addition to having her pussy impaled by the deity's cock, she now had one of her own hard and rocking in front of her with every thrust.
Sarah felt the most horny of her life and was constantly on the verge of an orgasm, which only increased with her having a cock now. She then thought that since it would only be temporary she would enjoy the moment, so she took her cock and started stroking it. New sensations invaded her, which took her far beyond anything she could imagine possible, but she couldn't take it anymore and said "Please Lilith....I can't take it anymore....I need to come...I beg you.....let me come."
"Needless to say, I'm already reaching my limit, I'm about to come... aahhhh.... finally I'm coming on someone.... finally after billions of years." Lilith said and came.
Just as the deity had promised Sarah came at the same time, the most intense orgasm she could ever hope to feel, the sensation spreading like an explosion through her body as cum gushed from the tip of her cock. In the end, the orgasm was so intense that she didn't resist until the end, immediately blacking out as she noticed it had started to subside.

When Sarah woke up she thought that everything that had happened was just a dream, realizing how real it was after seeing her dick, which even flaccid was still huge, and Lilith sitting nearby looking at her.
"Glad you woke up, I got scared when you blacked out. I'm sorry, after such a long time I ended up letting myself go, I ended up getting carried away and I took you beyond your limits." Lilith said
"Okay but... how long have I been out?" Sarah said
"You were unconscious for approximately 6 hours." Lilith said
"6 hours? I have to get back to the hotel right away, my friends must be worried about me." Sarah said
"I help you, with my skills it will be a breeze." Lilith said
