http://www.darkhorizons.com/xhamster-wants-to-produce-sense8-s3/ I say, go for it. Harness all that fapping for something good.
pretty much any porn you want - or so I've been told. I know, you're just asking "for a friend" right?
I have no idea what Sense8 is but I am well versed in x hamster. x hamster is virus free, as is x videos (another go-to site). Porn hub however might link you to sites that are not virus-free. porn dot com is virus free and gives you the option of watching clips in higher quality (360, 480, etc) and in 1/2 or 1/4 speed and that is always nice. If you need to ask why, I sure hate it for you.
