I Got Caught In My Underwear

Here is an embarrassing story that will hopefully make you laugh.
I was home on a hot summer night. I went out to my front porch to smoke. All the lights were off at all the apartment buildings on my street since it was pretty late, so I decided it was safe to go outside wearing just a t-shirt and underwear. I sat down and smoked for a minute and then all of a sudden 2 girls from the across the street came outside and were standing on their front porch, which is directly across from mine. Since I was sitting down, I don't think they could see that I was in my underwear. So I was pretty much stuck sitting there until they left or they would see me in my underwear if I got up. I decided to wait and see if they went inside. After a few minutes they went in but their hall door was still open. I decided this was my chance to get up and go inside without being seen. I stood up and made my way over to my hallway door. When I opened it the motion sensor light came on and you could see me bright as day. When this happened i noticed the girls standing back outside again. They were staring at me standing there in my white briefs and t shirt that barely covered the waistband of my underwear. Safe to say they got a good view of my tighty whities before I got in and closed the door. I was so embarrassed!
