Hey dude I'm a bit of a Waka fan too...what a knockout body. She doesn't seem to be making a lot of movies lately. She's been into the wrestling scene. I guess you know she is a really accomplished musician.

I just had a look at her twitter and see what you mean about the wrestling. While she looks good doing it, I kinda hope she gets back to business soon.
Those early films of her getting bent over and railed while playing the piano are pretty hot. She graduated to some reasonably hard core scenes within her first year in the business, like in NHDTB-073, where she seems to really get into fucking that fat black dude....A real freak at heart with musical talent, what a sight to see!
