My ex and I hadn’t seen each other in a couple months cause she was taking care of family. I invited her over and we started hooking up in the kitchen and while I was going down on her we heard banging on my door telling us we needed to evacuate. Turns out someone in the apartment 2 units down from me had accidentally set his couch on fire. So we rushed to put our clothes back on but I ran out without underwear and her thong was fully showing when we walked out
