My uncle is married to his third wife, my new aunt. This happened to me/us in 1991. I moved to the same town, trying to make my winter more productive. I would visit them often, being they were the only family around and making new friends gets harder and harder as you get older. At any rate my aunt is twenty years younger than my uncle and I'm ten years younger than she is. We would often have lively discussions around the dinner table. My uncle's routine would be a little discussion and off to the family room to fall asleep in his recliner. My aunt and I would stay at the table talking. Over time she would make it a point to bump into me while cleaning up the table or stand/lean on me while washing the dishes. I didn't mind, she smelled great, has a great body and certainly needed the attention, as well as I did.
One night while clearing the table, with my uncle asleep in the next room, she pinned me to the wall with her body and planted a hot, steamy kiss on my lips. It was a surprise, but not, I knew something was going to happen one of these nights. We proceeded to grope each other like two teenagers kissing for the first time! Man was it hot! I could feel her hard nipples pressing into my chest and I'm sure she could feel my dick pressing into her tummy. We parted and nearly ripped each others clothes off before we realized where we were. We regained control and peered around the corner to see my uncle sound asleep, snoring away.
This woman needed some loving. We finished the dishes with lots of kissing and squeezing. Man, I was ready to burst! We made our way out to the porch where we could see and not be seen. We went into the hot tub and floated around a bit before starting in again. Man this woman was hot to trot! She sat up on the edge of the hot tub and spread her legs, inviting me to finger her. I rubbed her clit and made her wimper in delight. I must have made her cum because she shuddered, moaned and fell backwards. I kept on fingering her, and rubbing her clit. She stopped me by pulling on my arm and made me get out to sit on the edge. She put her hand to her pussy and came up with some natural lubrication, jumped back in the water and proceeded to jack me off. It didn't take me long to start feeling the motion and she must have felt the tension because she wrapped her fingers around my dick just in time for me to unload onto her hand. Talk about bizarre, my uncle is sound asleep just on the other side of some glass and we're going at it like there is no tomorrow. We kissed and both let out a collective sigh.
We put our suits on, got back into the hot tub, started talking across from each other and out walks my uncle. We invited him in, and carried on as if nothing happened.
Of course we got together many times after that, either in the hot tub or taking late night walks where we would find places to masturbate each other. They lived in areas where the neighbors had large yards so we would do it on their lawns or the big boulders used in their landscaping. Most neighborhoods in the US are ghost towns at night. It was so amazing to masturbate under the stars in all these different yards. Ah, the good times!
