I explained myself earlier, Natalie and Sydney(especially) both use acting, psychology, and camera work to create a disturbing mood on purpose. It is not for the for normal fans of "family roleplay". They make it feel real, raw and unfiltered (since they always do simulated sex/pov), to the point where a lot of people actual feel guilty watching their work.
To put it simply:
- It's one thing when the premise is "Your horny mom or sister decide your the one for them, and they seduce you"...
- it's another thing when the premise is "After years of YOU being abusive and toxic, your mom/sister/aunt are finally just so lonely and broken that they let YOU have there way with them, and YOU are the only one that can satisfy them now. So they take your cock anytime YOU want, but with cold dead eyes (Sydney) or with psycho tsundere crazy eyes (Natalie)."
