I get ready and head out to the living room to see what my brother and his friend are up to. Snapchat sex bro is missing, and his friend is by himself. He says that my Snapchat brother went to pick up his girlfriend and would be back later. We hang out for a bit, then I get curious and ask my brother’s friend if he had seen my missing panties. He flushes with embarrassment, and tries to avoid the subject.
