Morag, the black hair, will be replace the girl in the image with the real people. The redhead and pink haired girls will be futas with generally big dicks and will replace the guys that Morag will be giving a blowjob and hand job to. As for the guy on the bottom of the real image, there will be a random black futa instead, but their face will not be shown at all; their hands should also be grabbing her ass like the real image. Background can be anywhere the artist chooses, Morag's face should be visible like the real image, and Morag will have an ahegao face.
Lastly, all of the girls will be completely naked, except for the red hair with her earring and jewel from her reference image and Morag will keep her black leggings from her original image.
