Cecilia in comparison with Sophie makes more naughty content. I would call it as something similar to imaginaty softcore content. She shows nothing, but making:
dildo blowjob, dildo boobs fuck;
squeezing, shaking and bouncing her boobs;
tongue out and spit on her boobs;
She's just trading the fantasy. She plays in the imitation.
Cecilia has more potential than Sophie. Sophie content is only implied nudity.
Also Cecilia often show her nipples through t-shirt.
Ashey made implied nudity too, but sometimes she showed nipples. Ashley was the closest to topless
