My Uncle John is going to be here any minute now. My sister and I are anxiously waiting for him to arrive. He is our favorite uncle. He is pretty young looking and active for his age. He also doesn't act like a grownup but he is. He always finds time to be with my sister and me. He takes us out to the mall, movies, dancing, and to the beach.
My sister and I are very close. We are each other's best friends and there is nothing hidden. Since we were little we would visit Uncle's john's house, he would host us for a whole weekend and let us use his pool and his hot tub. We used to walk around the house all day in our bathing suites or tank tops and panties. We talked him into wearing his speedos some of the time. It was a very cute sight. We would put suntan lotion on each other. But that was all so innocent and sweet and we loved him so much then.
Then we grew old. I turned 18 and my sister 19. During one of our visits to my uncle, my sister and I stayed up all night talking about how hot Uncle John is. That is when my sister asked if I saw his "tent" earlier that day. I knew what she was talking about. I had seen Uncle John's shorts get really bulgy. It seemed rather large of a bulge, which he always tried to hide from us. It didn't help that he was giving us back rubs in the hot tub. We felt special knowing that my sister and me caused Uncle John to have a huge hard on.
That night we wondered what it would be like to see it for real. My sister wondered what it would be like to touch it. She also wanted to know if I ever wondered what it would feel like if we were to grind our butts against his tent. We laughed but then the laughs turned into moans. We both noticed that in the darkness of the room, thinking that the other person would not notice, we both were rubbing our clits. When we both realized that our hands were in our panties we moved closer to each other. Our sides touched. We started to feel the heat from our bodies which helped us get over the edge. I lifted my tank top over my chest and started rubbing my nipples. My sister did the same with hers. Right when my sister said:
"I bet Uncle John has a huge cock. Wonder what it would be like to touch it. Wonder what it would feel like if he was touching us like this."
We both moaned and came almost at once. We came and came and came. Knowing that my sister is now copying me I lift my both fingers out of my pussy and sucked on my pussy juices on my finger. It was almost time for Uncle John to come tuck us in. He usually sits on the edge of the bed and talks to us for a few minutes and then kisses our forehead and leaves. This time we told him we were scared and we asked him if he'd like to snuggle with us and put us to sleep. He agreed and we told him to slide in between my sister and me so we can snuggle up to him at the same time.
My sister wraps her legs around his waist but then the leg slides lower and now she is deliberately resting her soft shaved legs against his big tent, which was growing. It was my turn to follow so I replaced my sister's leg with mine. Only my leg was placed in a way that the tent was resting between the undersides of my knee, which I bent immediately. I heard a soft groan and moan from him and all I could do was breath heavy and smile. We cuddled with him pressing our breasts against his chest and kissing him all over. I could feel the hardness of my nipples grind against his chest. At the same time our legs continue to assault on his thing which was by now huge fat thick and large.
