Sakura Haruno, and yes it was!

"Wow, Ino sure knows how to give a friend a treat," Sakura sighed, patting her stomach. Ino had invited Sakura to lunch with Team Ten after a hard day of training. It was time to head home for the day. She decided to take a shortcut through an alleyway. She was too tired to go roof hopping.

She was thinking about what to study for her medical training, when pain shot up her toes, courtesy of her stubbing them on something hard. "Yeowch!" she yelped, hopping up and down on her other foot. She then glared down at the ground, irrational anger bidding her to smash whatever it was she had stubbed her foot on.

She then blinked as she saw the gleam of gold. Huh, if it was valuable, then that meant she should hold off on smashing it. She picked up the object in question. "...huh, I think Temari showed me something like this once, some kind of exotic oil lamp... Though that one was made of brass, this one's gold," she assessed quietly to herself.

She then began to brush some dust off of it, before she shrieked as it jolted in her hands, and spewed pink mist at her. She dropped the Lamp and tried to jump back out of the alley. The last two years of "dodge" training with Tsunade, while traumatizing, were almost enough for her to get out of reach of the mist, but a tendril managed to grab her around the waist, and dragged her right back in. She tried to scream and reach for a kunai, but the cloud thickened right over her mouth and limbs, holding her in place, and seeping into her skin.

She didn't know how this mist was solid, and thought it might be some kind of ninjutsu, or fuinjutsu, maybe even genjutsu. She attempted to manipulate her chakra to dispel it, or gather strength to break free, but to her surprise and horror, she found her chakra being suppressed by whatever this gas was. Her horror only grew when her clothes evaporated, baring her body.

Then, she jolted as she felt a rush of pleasure and moaned as the mist stimulated all of her nerves in ways she didn't even know she could feel, which surprised her, as she was a medic. Her body then started to change. Every hair follicle she had below the neck was pushed into dormancy, and what fuzz she had there dematerialized, joining the mist, including her small tuft of pubic hair. Then, her breasts, a bit modest, but nice and perky, swelled up about half a cup size. Still small enough to fit and compliment her frame, but definitely more noticable. Her hips also flared out a bit, and her ass, her best feature, tightened, becoming even more heart shaped. All of her small, faded scars from training and combat were also erased.

She moaned, feeling the pleasure, before the smoke continued to work, this time going to her mind, whispering directly into her soul. Non malicious promises of pleasure she couldn't comprehend in her current state, the current sensations only being a taste, power, and temporary immortality, the price for which being having to obey whoever owned the Lamp, and the transformation came with a submissive nature, making the price seem like another benefit.

Thoroughly seduced by the experience, the pleasure too good to pass up, Sakura didn't resist, and then, the mist proceeded to solidify around potions of her body. Poofy harem pants formed around her lower half, made of extremely comfortable and smooth pink silk, and also transparent, so her feminine petals were still easily discernable through them. Her breasts had a skimpy top "covering" them in the same style. Her lower face had a veil draped over it, the corners of which were attached to a circlet with an emerald matching her eyes encrusted in it. Her wrists gained golden bands, also each having an emerald in them. Thinner bands, not adorned with a gem this time, formed around her biceps, detached pink silk sleeves flaring out over her arms.

"Unh..." she crooned as the mist thinned around her mouth, allowing her to speak again, now that she wasn't trying to scream for help anymore. If "help" came at this point, she would frankly send them flying herself rather than stop the process. Her toes started to evaporate as the vapors began to gather around her lower half, but it didn't distress Sakura, even as the effect crawled all the way up her lower extremities, and stopped once her pelvis was made of the iridescent gas. It basically formed an absolutely beautiful tail that remained connected to the Lamp spout.

Sakura smiled under her new veil, and crossed her arms under her enhanced chest, gazing down at the tail, and undulating it slightly, mesmerizing herself briefly with the motion. The movements came naturally, like it had been a part of her body her whole life. She tugged lightly with the tail, but found she couldn't detach it from the spout of the Lamp. This didn't concern her however. Her mind had been rewired to enjoy being bound.

As such, she gasped in pleasure instead of fear as she felt herself getting sucked into the Lamp. She eagerly went with the flow, and let herself get settled into the Lamp to await the one who would come to claim her.
