8 XXX : distension

That's not a Hitachi. It's a Lelo smart wand and they are 10x better!
Imagine the feeling of a dick in her pussy with that in there.
Source is Roxy Raye in Anal Pros released by Evil Angel I could not find a stream yet because the scene is relatively new. Sorry.
Not so much distention as insertion(you should cross-post to /r/insertions if you haven't already), but a quality post nonetheless! Hot.

I suppose you could use it as a back smassager, too.
One way? You mean the best way
