Mush to her relief, though it took a few years, Chrissy's absorbent expanding implants finally reached their designed size. With a semi-porous shell, these implants absorb the body's natural fluids and expand as quickly as the skin allows until they reach the volume specified when ordering. Made from polyurethane, they adhere to the chest wall, eliminating the need for a internal bra or any breast support at all. Though the implant will forever hold its size and shape after being fully expanded, they will require draining periodically to reduce the weight. but this is done quickly and easily with just a needle stick, resulting in implants weighing only as much as a synthetic sponge that size. Some of her friends feel Chrissy went too far by ordering the 80k size, however, she is quite excited with the prospect of living life with such enormous implants.
