Nah, they had a fingering + kissing video a while back when they first started, but it leaked so they got mad and refused to do more. They've made out with each other after that but never any fingering, scissoring, or actual sex.
The Mods may have deleted the comment for all I know but someone claimed earlier in the thread that they said they've done the act with each other in real life on a Podcast they were on, but refused to sell the actual stuff since the leaks were happening hard.
Podcast aside, you can actually Google them and see a statement they made about their stuff leaking.
Can't be bothered to matched the dates with that of their first vid where there was more than just kissing, but I believe this was (or they claimed) also around a time that incest was being monitored by OF as well, but it was definitely more of a "because we're being leaked" thing, considering other Twins did more intimate acts and never stopped.
The recent Incest vids they did that leaked are from private lives/custom requests that they made people pay for, and it's just now leaking out. It's likely the Fansly stuff mentioned above is the way to those.
