I was home alone, and just finished with a shower. Naked, I picked up my clothes and walked them to the laundry. I heard someone at the front door, then I heard it open. My daughters friends just walk in all the time, and I was afraid it was one of them, and I had no place to go. I started reaching for my dirty clothes to put on when my niece, who is 30, and from my wife's family, walked into the room. I tried to hide but she told me it wasn't necessary. I found this very exciting and started to get hard, which she found amusing. As she continued to watch and stare, I started to think about trying to get her to do something. She read my mind, and said she wouldn't let me touch her, and wouldn't touch me, but she might help me if I wanted to make myself cum. She went into the living room and told me to sit on the couch. She unbuttoned her blouse and loosened her bra, just enough for me to glimpse at her breasts. She ran her hand up and down my chest and stomach while I stroked myself faster and faster. In a very short time, I came all over my stomach and chest. Some got on her hand, which she partially licked off herself, and also put her finger in my mouth. Yeah, I cleaned my cum off her finger. She continued to put her fingers in the cum on me, and then either lick it off, or put it in my mouth. When she took the last, large glob and put it in her mouth, she leaned over and kissed me, and we shared that last bit. She said that we maybe should think aboout helping each other out the next time one of us was horny. Now she finally gave my cock a little squeeze. I tried to touch her breast, but she stopped my hand and said that we needed to save something for the next time. I don't know when that will be, but whenever it won't be soon enough. Thsi girl isn't the prettiest, but one of those girls that is just plain sexy. I'd probably do her right in the front yard, in front of my wife and pastor if I had the chance. She's been my favorite fantasy for years.
