A masterpiece, top quality, ultra-detailed modern digital hentai, low-angle shot from behind, a post-apocalyptic city alleyway between tall, ruined concrete high-rises, abandoned old wrecked cars. A girl with a short bob, white hair on top and bright yellow underneath, is sitting astride her partner with her back to him, deep penetration, her huge, round buttocks, glistening with sweat and lubricant, are spread apart, drops of fluid trickling down her thighs and buttocks, a dark, shiny, torn, cropped jacket with the yellow inscription ‘HENTAI 90’ on the back, a flush on her cheeks, her mouth slightly parted, her body covered in sweat. You can see the cock entering her. Glossy, wet skin, copious fluids, high level of detail, cinematic lighting, exaggerated forms, modern ‘wet shiny hentai’ style
