The crease down the front of her abdomen, I think may be from liposuction. Just a guess.
I like my women a little more chunky than that. I love a woman that appreciates the good things in life, and that includes food. If you can tolerate a few more pounds, you can enjoy meals together a bit better than if you are eating a burger and fries while she eats part of a salad.
