Well, I would have liked to have "experiences" with Wendy, so I could be a Wendy expert...
Out of jokes - I hope you got it, I mean I hope the translation from italian to english didn't waste it-
I can say it is prettyn usual, in big boobs hardcore movies, that guys come over girls boobs. The focus is on the boobs, the fetish is the boobs, so it looks logical.
Then I had the same impression: Wendy - who I adore anyway - looks not very "involved and passionate" in her hardcore scenes , not as much as Letha or Tiffany.
Btw, in those movies the guys never cum so much and their dicks - probably to enhance boobs dimensions - are very small. Only a few times I have seen the big boobs queen making movies with guys like Ron Jeremy or Peter North. I remember a scene of Wendy with Rocco Siffredi (italian, of course): that was worth to be seen!
