I was reminded of a funny story from about 7 years ago when I was away for work. There has been this guy I met at the hotel bar at a conference the night I arrived for a work conference... We got drunk and ended up hooking up that night and we parted ways in the morning. At lunch time, I got a text from him asking to meet up for a coffee... So I left my co-workers for a bit and went to meet him in the lobby...As we finished coffees, he asks if I wanna get a quickie on in the bathroom.. to which I smiled and said sure but it has to be quick. So we go into the lobby bathroom, start kissing and then my dress is pulled up and we're getting it on. He whispers "I'm about to cum" so I drop down to my knees and start blowing him (Trying to avoid making a mess). I took his dick out for a second to jerk him off a bit thinking it would hurry things up and it worked, he started to cum and I put it back in my mouth. In my mind, this made the most sense since I had to go right back to our booth at the conference and didn't want to be disheveled looking. After he finished, we headed out and I checked myself in the mirror... everything looked good. I headed back to our booth and proceeded to talk to the random people who came to ask what my company does. Its nearing the end of the day one of the sales guys comes over and hangs around for a while chit chatting with me, asking how things have been during the day... etc small talk. He helps me pack up the booth for the day and we head down to the bar for a drink... As we're standing at the bar, some random lady at the bar pulls me aside and says, "I have a tide pen if you need it"... Looking puzzled, I smiled and said ohh, thanks, looking at the front of my dress thinking I spilled something... She looks back at me and points to my shoulder, and I reply with a puzzled look. She says you have some stain running down your back from your shoulder... I immediately break out in a cold nervous sweat, grab the tide pen and run to the bathroom (same one from earlier funny enough). I try and contort my body to see and there it is, a faded white stain, running about 8 inches down the back of my dress from my shoulder. It was very pronounced since I was wearing a navy blue dress. It was at the perfect height where I couldn't see it from the mirror without bending and twisting... Realizing immediately what it was, I couldn't help but laugh but also feel embarrassed... That first shot when he came landed perfectly right over my shoulder and dripped down my back... I cant even imagine how many people saw it or what they thought.... I hurried to my room and changed and went back to the bar... Of course my co-workers there commented on my quick outfit change and the sales guy who was with me at the booth says ... "I was going to say something but I didn't know how to... That looked a little suspect"... I met the guy again that night and told him the story and showed him the dress.
