This happened to me just last week. My mother decided to go on a one month trip to Europe for her 65th birthday. She had asked Judy , her neighbor, to watch over her house. During the first week that she was gone I stopped by her house to check on things. I was feeling really horny so I decided to strip and jack off.
Every once in a while I get the urge to taste my cum. To do this I put my feet up on a wall and jack off letting my cum fall right into my mouth and all over my face. I started doing this because I would always lose my nerve once I came and would not lick my cum from my hand. Well as I became aroused I positioned myself to catch my load in my mouth. I never heard anyone come into the house but just as I was about to cum I heard Judy say, 'Oh my god ..I'm sorry' and she ran out of the house. I was so scared about her seeing me I quickly dressed and went home.
I did not go back to my mothers house for several weeks. But I knew I needed to clean my mothers pool before she got home. So the day before she was to get home I went over to her house around 8:00 a.m. Once I had cleaned the pool I decided to get some sun. The pool has a very good privacy fence around it so I decided to put on one my thong swimsuits and get some sun.
About an hour into relaxation I hear the gate open and it was Judy. She said she was coming over to check the house one last time and did not know I was here. She walked up to where I was sitting and asked if she could have a drink. I told her she could but I was not really dressed to get up and get it for her. She told me not to worry because she had seen me naked. Boy was I embarrassed! She then told me she asked her daughter what I might have been doing and her daughter told her to ask me. Judy said her daughter thought I might be trying to shoot all over my face.
I reluctantly admitted to what I was doing and asked her not tell anyone else. She said she would not tell anyone as long as she could watch the entire act. She black mailed me by telling me she would tell my mom if I did not do it for her. She suggested that I go ahead and get it over with. After a little coaxing we went inside the house and pulled my thong off. My dick immediately sprang into an erection. Knowing I would cum very easily I put myself into the position on the wall. Within minutes I began to shoot loads of cum all over my face and into my mouth.
I was so horny that I remained naked until she left. There have since been more interesting encounters with her.
