Write the following into a story. My mom and sister were super hot, mom was very well-endowed and the fact she walked around the house in her sexy underwear made that obvious, and my sister who was just as busty seemed to copy moms way of dressing, just in even more risque underwear. I decided to join them in only wearing underwear around the house, but my huge manhood would constantly flop out. Every day both of them would get multiple eyefuls of my impressive manhood, it happened so much that my sister suggested I take my underwear off.
