Oversized undies and the mystery of the escaping you know what...

I have been buying and wearing Mr P underwear for a few years now. I buy the same style and the same size every year, normally around wedding anniversary time, so have a nice pair on for the big night... 😅 This year I went to buy again, same size same undies... After my shower and getting dressed I noticed they seemed a bit bigger (I haven't lost weight, if anything I have gained a few kg)... Off we go for anniversary dinner, crowded restaurant and as I take a step up into the dining area, my jewels pop out the side. Had to walk all the way to our table with my ******** dangling down my leg... Eish... An d then adjust them back in... The next day I measured them against my old ones and they're at least an inch bigger... Now, obviously the store won't take them back, so what am I supposed to do with 5 pairs of oversized underwear the whole year? Damn... Can't have my boys escaping every time I wear a pair...and don't think the wife would be too impressed if used them to wash the dishes, cos that's about all they're good for.... Hmmm
