This girl name is Unabara Yuka, she is an original character created for a hentai doujin. She was created by the hentai doujin artist Kumacchi.

In the story, she is an innocent and somewhat clumsy girl who works as an idol and bikini model. She falls asleep on the beach after some men put a sleeping drug in her drink.

The girl ends up being raped by the men, who then blackmail her and force her to become their lifelong sexual slave.

I made a specific LoRA to be used together with this one so that she looks exactly like in the original doujin hentai. Please use them together to generate images identical to those in the doujin. I recommend using this LoRA at a strength of 1.0, and the Style LoRa at 0.7 for best results, so the generated images look the same as the original artist’s work:
