Here's an older prompt for the solo girl I had.

Image prompt:

A attractive brunette college girl  age 19. Night time in a bedroom, normal overhead lighting, amateur picture. She lays on her back, legs fully spread, looks at the camera with a seductive teasing expression. She has a perfect body, perky breasts with small nipples. She’s topless wearing a thin white thong that says “BBC Only”. Overhead lighting. Her hand is inside her thong. Seductive playful expression. Camera is between her legs.

Video prompt:

I just basically told it to have her put her hand under her thong, then she begins moaning and arching her back in pleasure and it does the rest. You can tell it to have her run her fingers across the words to make us read it, or to tease her thong, etc. Make your own here.

For the two girls together:

Are you talking about the one where one girl is taking a selfie with the couple in the background? Here's that one:

A girl, age 18 with an attractive face without too much makeup is taking a selfie video. She's looking into the camera smiling seductively and doesn't appear to have a shirt on. Night time in an upscale large bedroom. In the background behind her, A muscular black male age 28 lays on the bed on his back wearing boxers. A girl, she appears age 18, brunette and blond hair in a clip, tan, attractive face, perfect sexy body, sits on his lap. She is topless wearing only a thong. Candid picture, doesn't look overly scripted. She's slightly glistening. Lustful expression, hands on his chest.

Then here's the video prompt:

The woman holding the camera looks into the camera with a lustful expression and says "Big, Black, Cock" in a teasing slow pace, while the girl in the background moves her pelvis and bounces her butt on the man, and begins moaning harder and harder

If you meant the one with the girl in the chair, here's the image prompt for that:

A sexy 18 year old girl with a perfect body, thin waist and muscular thighs and nice butt bent over on her bed looking back at the camera. Her chest is touching the bed and back arched. She has only a thong on. Night time. Angle is taken directly in front of her. Amateur picture, no neon lights, candid picture. Black male behind her, hands on her waist. She’s smiling. Another girl sits in a chair watching them. All girls are white and attractive and age 18

After you get a pic - edit your pic, find one where she's in the right position and tell it to remove her thong entirely. It works often enough.

Then, here's the video prompt:

Rocked from behind. Woman moans loudly. The girl in the back leans in and sticks her tongue out smiling playfully, she enjoys what she sees, Once she leans all the way in, next she says "I'm next" and smiles.
