If I remember correctly, Keisha has intimated that when she had an appointment with her breast doctor, he was impressed with how much skin she has. Definitely impressed me. 😁
In the below pic Keisha is in an upright position, and despite this the skin under her breasts appear to definetely not be under any kind of duress. This indicates that she may have some kind of internal support structure that is carrying the weight of her enormous implants. Curiously there is also a lot of slack skin on the sides of her boobs. So likely not gravity that has been causing all the stretching.

What is the cause then? Maybe its an effect of her breasts being constantly massaged, caressed, worshiped and enjoyed. By Keisha herself, or by someone lending a helping hand or two.
