I would describe Serina's ass as athletic and muscular as opposed to fat. It's definitely heart shaped and her overall body is toned and fit. She has an AMAZING body. Perfect body IMHO. Flat stomach, well proportioned breast, juicy ass, proportioned hip to waist ratio, and a tight kitty.
She's my favorite LSC girl after her roommate Angela.
I'd empty out my 401K for a doubles session w/ Angela and Serina. Lol, j/k...maybe.
