I liked it when director Mike John limited his female performers to those with natural breasts. When I watched those scenes directed by him, what I saw were OEM breasts.
Most often, if the performance is great and her face is "easy on my eyes", I am not distracted by implanted breasts. Those early implants could be dangerous, with silicone leaking into a woman's body. Krissy Lynn is an excellent performer, in my humble opinion. Great vocals.
