A bizarre new disease swept across the globe. It's symptoms went unnoticed at first, as those affected only suffered a light fever. But then, women began to report that their breasts were getting smaller and perkier, until they were reduced to mere buds, and, in the final stages, they were left as flat as boys, with small, pink nipples that were extra sensitive. Pregnant women could still produce milk, and would temporarily gain small breasts, but once they stopped lactating, their breasts would shrink once more.
The loss of breasts caused women to suffer from body image issues, and men the world round bemoaned the loss. Science raced to find an answer to this crisis, but most women simply resorted to implants or the old stand by of stuffing their bras to regain the illusion of maturity.
No cure could be found, but finally, the world began to accept the new normal. Women's fashions changed, and bra manufacturers went out of business.
All in all, while it was interesting, it was also boring. Back to the drawing board! What kind of crazy virus would Jack make next?
