Your stories and pictures turn me on and make me remeber when I was in Asia a few years ago. I didn´t wear a robe, but anyway...
I was travelling with a friend who had seen me naked many times, so no big deal. This day I was by myself in the hotel room, my friend was away on his own. I went in to the shower and as I soped my dick up I had an erection and started jerking off there in the shower. Just as I ejaculated I heard a knock on the hotel room door. I thought it was my friend, so I just shouted "Come in, it´s open!" No answer, just another knock. I shouted again but no answer. A bit annoyed, I went to the door, naked. My dick had started to slacken but it was still swollen from the hot shower and from just having been erect and jerked, so it was bigger than normal. Stark naked I swung the door open, and there in front of me was not my friend but a young man working at the hotel. He bowed and looked very embarassed as he handed me a plate of fruits. He then bowed aganin and walked away still facing me. During the whole procedure he never spoke nor looked me in the eyes, he had his eyes constantly fixed on my penis. I shouted "Sorry!" after him as he disapeared. But I don´t think he minded really, as he couldn´t take his eyes off my dick. I am pretty sure he had been standing outside the door for a while listening to me jerking off and groaning as I ejaculated, hoping to maybe see me in my robe and catch a glimpse of my dick as I opened the door. Well, he sure got to see my dick, almost half ercet! Must have made his day!
