That's Lela Star, who's come up in a couple other threads in this forum -- a search should turn up some additional videos. And those breasts are actually real, believe it or not. She recently had a boob job for some unfathomable reason, but this video was shot prior to that.
I wouldn't say she has the perfect body, though. If you look at her closely, she doesn't really have much curviness in terms of her hip/waist ratio; her torso is more or less the same width from her chest to her hips. But she's still a tremendous hottie. |
