I guess Mac n cheese is just a roleplay where she straight up acts like she's getting banged.
The others might just go for teasing, bj or a handy.
I don't think she ever touched herself on stream, or teased that she's actually doing it.
Keep in mind back at globie she was just very suggestive to not get in trouble. Always heavy on the roleplay. Then she wasn't even sure about doing NSFW, but gave it a shot.
She seems comfortable though and makes more things than expected, so I wouldn't be surprised if she slowly does more things
