I woke up early and went to washroom and saw my mums panties lying their on the washing machine … guess she changed it late night and didn’t bother put it inside .. now I have seen and felt those many times before so I wasn’t surprised at all..but for the first time out of curiosity I wanted to know what size she is … so I checked and found out her panties said 90 cms.. I am so confused I don’t know if Women’s sizes are different but I myself use 90 cms underwear and anyone can say for sure my mum is a lot bigger .. and yeah her panties are always super stretched .. like 110 cm or 120 easily … why would she buy small size and stretch them?? Can anyone help me understand this?? ..does all ladies do this?? ..is this comfortable?
