This is definitely one of my favorite sites about masturbation I have stumbled upon today after much searching this is my favorite.
I went to a clothing store near my house, the store only had 2 dressing rooms one of which was filled with boxes so only one could be used which was fine because when I walked in I was the only customer. So I would try on a few things at a time and go back and shop. The third time I came out of the dressing room to continue shopping, a family had also come into the store, A mother, her young daughter (about 18 months) and her son who was about 14, they appeared to be hispanic. Anyway I continued shopping and found a pair of pants I wanted to try on before I left but when I went to return to my dressing room the boy had taken my place. So I paced back and forth waiting for my turn to go in. Every once in a while he would come out to model for his mom the new clothes he was trying on and I could see that they were going to take their time so I walked around with my potential purchases until finally the boy came out in his old clothes. I wasted no time heading towards the dressing room to claim my territory when I got close to the door I heard the boy say an urgent 'wait' but his mom said 'let him go in we are leaving I got other things to do' so I went in and after I closed the door I turned towards the mirror and I could see why the boy made such an urgent request for me to wait because on the mirror was his semen it had to be his considering we were the only 2 males in the shop and I was the last one in the dressing room before him, I knew it wasnt mine and the mirror was clean when I went in. I became extremely excited upon seeing this unexpected surprise and I stared at it for a while and then I tasted some and then I knew it was semen. Thinking back on it that kid could have had any kind of disease but as horny as that made me I did not give that a thought and ate every single bit of that slimy, salty semen he had left on the mirror. When I came out the family had already left and I bought my items and went to the grocery store next and guess who I passed by in the store the boy and his family when he saw me he had a guilty look on his face and quickly turned the other way. When I got home I released some of my own semen onto my pillow thinking about what had just happened.
