Yes 100%. It is a very good boobjob, smooth saline implants, that's why they move around so freely. But if you look closely when she plays with them you can see that the implant slides around under her fingers rather than really squeezing them.
They are natural and I doubt you ever have seen or held a pair of natural tits in your life to come out with this shit. Nothing in the pics/vids you posted looks remotely fake. I wouldn't even call her tits perfect, I've seen better natural tits. The gland sits right under the nipple, for men and women. For women with big tits (not just fat tits) that area under the nipple will have the most density. The "rippling" is just stretch marks, which every girl with big tits has.
