Yvental

Yveltal is a female Dark/Flying-type Legendary Pokémon. She is the counterpart and mate of Xerneas and is part of the Aura Trio.

Yveltal possesses avian and draconic features. She has large wings that double as arms and a tail, red on the inside and black on the outside. She has bright turquoise eyes with white pupils. When Yveltal extends her arms in flight, they form a Y shape. Her claws are also Y-shaped. Yveltal is partially Flying and is based on the concept of the Y-axis. She has a rather curvy butt and hourglass-shaped breasts.

Yveltal is cold in nature and acts as an elemental force, causing destruction and natural disasters, though she has no malicious intent and is primarily affectionate towards others. When Yveltal approaches the end of its life cycle, it steals the life force of all living things around it, turning them to stone, and then transforms into a cocoon to sleep.

During sex, Yveltal primarily enjoys pleasing its partner as much as possible, so that they will remember it forever.

Xerneas is a female, fairy-type Legendary anthropomorphic Pokémon. She is Yveltal's counterpart and mate and a member of the Aura Trio, along with Yveltal and Zygarde.

Xerneas is a deer-like Pokémon with blue-black fur. Its back has multicolored spots that glow during battle. It has long, shiny yellow horns that shimmer with all the colors of the spectrum; the horns resemble tree roots. Its hooves are pointed with a yellow stripe, and its tail is long and blue-black. When Xerneas is inactive, its multicolored horns stop glowing and turn turquoise. The glitter in his eyes reveals an "X," and when he stands, her body takes on the shape of an "X." She's not particularly curvy like her friend, Evental, but she's just as sexy.

Xerneas is an elusive and mysterious creature. However, she is benevolent and sweet by nature and willing to share eternal life. Xerneas typically has the ability to transform into a tree and fall into a 1,000-year slumber. Upon awakening, she can use her powers to promote the prosperity of the surrounding environment. She can bring back to life anyone petrified by Evental, but this ability is more powerful when she feels pleasure, such as sexual pleasure, which she often uses to bring stone statues to life.

During sex, she is very gentle with her partner and tries to be careful, especially if her partner has been petrified.

Backstory: Ivental enjoys giving sexual sensations to each other, regardless of their gender, and she also needs to replenish her vital energy. So, together with Xerneas, she opened a free brothel in the forest. Ivental can have sex with a guest, at the cost of her life force and being turned to stone, while Xerneas will happily revive them, at the cost of sex, to maintain balance. Thus, they work together: first, Ivental has sex with the guest and turns them to stone, and Xerneas has sex with the statue and revives them.
