Of all my fantasies, this one makes me quiver, even after 20 years.
In my fantasy, I get to travel back in time to my teen years, and see myself. I am invisible. First, some background: Mom slept in one trailer, while my brother and I basically lived in another one just a few feet apart on our land. Because of this privacy, I had never been caught.
Mom was casual about sexual things, but I was too shy to talk about it. She is twenty years older than me and always has been very pretty. I found a book of hers about female sexuality and enjoyed the stories in it. Somehow, there was a picture of her naked that was put in my dresser. Once, she barged in my room and said, "caught ya!" Later, it occurred to me she was trying to walk in and catch me in the act. She may have actually caught me years later but never said a word. (I contributed a story about that on here a few years ago).
On this night, my brother was out with friends. I was alone in my room watching a movie. The invisible me is able to put thoughts inside people's heads, so I give myself the idea to get a pair of Mom's black panties and use them to pleasure myself. The feel of the satin on my balls drives me wild. Next, I "prompted" Mom to go have one of our talks. I was in my own world, enjoying the moment so much that I failed to hear her knock on the door of the trailer and come in. Invisible me saw Mom approach the bedroom. Teenage me was on my bed, pants down to my ankles, beating my meat.
My door swung open. "Billy, do you need anyth- well, well, well, what do we have here? You like my undies, huh." At that moment, I erupted all over myself. I jumped and tried to cover up, but to no avail. My feet tangled together, causing me to trip. She laughed. "Oh, no! Please don't tell anyone," I begged, nearly in tears from the humiliation. She teased me for a second. After apologizing to her for using her panties, she said I could have them, and gave a me a hug. After the embarrassment wore off, I kissed her hand and told her what a cool mom she was. Invisible me saw it all!
P.S. I think everyone should at least get caught once by your mom. It calms your worry about it. The first time getting caught is always the most embarrassing. Am I right?
