We only have 1 bathroom and it's situated in a hallway between my room and my parent's room.
So, it was like 4am and I had to pee. So I drowsily got up and headed to the bathroom. I stopped because the light was on, but the door was open. I stepped up next to the door and asked if anyone was in there. Dad yelled "yow!" for some reason lol. Anyway, I apologized and started leaning on the wall for him to come out.
...that's when it happened... I wasn't paying attention so when I saw him step out I glanced his way. He's just standing there totally naked looking at me. I was still drowsy so it took a second to register in my mind was I was looking at. I shouted "oh gosh, I didn't know!" And looked away as he ran his butt down the hall.
Why didn't he warn me? All he would've had to say is that he was naked and I would've gone back to my room. Why was he in there, fully naked with the door wide open? Thankfully I was too sleepy to register any details. All I remember now is his butt when he turned and I realized what happened.
Work in progress, please be patient.
