Pornstar Sisters in the Same Scene Together / Pornstar Sisters... ******????

[humbawe1]

I came across two sisters that make porn together named Premium Link Upgrade and Roxy Lane. Their porn is hot but I don't get it. Isn't this ****** or bordering very close to it. I don't know how two ******** can pretty much almost have sex with each other, be ok with that, and produce it legally.
