I was genuinely concerned about my ass. It seemed that none of my panties were fitting. I honestly thought that somehow, overnight, my ass had expanded to fit the curve of my desk chair (seeing as that is the place I spend the most time pretending to do work).
But no. Thank god. I realized (well, desperately hoping) that the shrinkage was actually because I washed my underwear in hot water. I've always been nervous about doing clothes in hot water and usually just do warm. But when I was measuring out detergent last time, I thought perhaps I ought to try hot on my whites/panties/towel load.
At least the mystery is (probably) solved. And I will never do hot washes again. I will however, continue to monitor my ass growth to ensure that the studying (*drinking*) the last few weekends (*all week*) didn't do permanent damage to my ass width.
