I just saw Sienna in "Your Mom Tossed My Salad 5" and damn... she does a lot of ass licking in there. Other than that, she doesn't do much of anything else out of the ordinary except maybe some very light ass fingering for literally a few seconds. The scene is pretty good except for the fact that her male partner is apparently Forest Gump's long lost retarded brother.
BTW I think her tats have gotten even more widespread since she got all that work done a month or 2 ago. I've already seen the huge mural on her back & ass, but now she has this giant bleeding rose that covers almost 1 entire ass cheek and another giant rose on her upper back that has yet to be colored in. So it looks like she's still not done yet! I know a small minority of guys get even more turned on by excessive tats everywhere, but she's gone way too far for my tastes. She's getting into the realm of tattooed fetish model which I feel will cause her to be offered less work in the future. She must be going thru some pre-midlife crisis or something.
