Helping My Sister

Here's my story. Two years ago, I spent a weekend helping my older sister Janice clean out her vacation home. She had recently become a widow and decided to sell the place. It's a nice little cabin, no AC or modern features, but it's next to a small pond with no neighbors nearby. It was a hot day and I got very sweaty helping her clean. In the middle of the afternoon, my sister says "let's go down to the pond" and cool off. She's got a six pack of beer. I drop my tools and follow her. When we get to the water, she tells me she's going to strip down and jump in.

My sister is in her mid 50s, but she's still got some nice curves, so it was hard not to look at her mature, but naked body. At first I thought I would just drink some beer to cool off, but my sister beckons me to join in, so pretty quickly I strip and join in. After swimming around a bit, I get out of the water and grab another beer. My sister does the same. We're standing with our feet in the water, still naked, drinking beer. My eyes keep wandering to her breasts and nice broad hips. I start to feel my member stir. My sister notices and smiles. She tells me its been a while since she's seen a naked man and cock. I blush and stiffen a bit more. Then she reaches out and touches the head of my penis, running her finger over the skin. Now I'm nearly at full mast. Things are a little awkward by now, so I stammer that I'm going to finish working and head back to the house.

So, we have dinner and things are kind of normal, but I feel a sexual tension in the air. When I go to bed, my room is stuffy from the heat, so I decide to sleep naked under the sheet. I'm trying to go to sleep, but the heat isn't making me comfortable. Suddenly my door cracks open and my sister walks in. She sees I'm awake and sits on the side of my bed. Janice is wearing a long white t-shirt and nothing else. She asks, "are you as horny as I am?" Before I can answer, she puts her hand on the sheet and caresses my member. She realizes I'm naked under the sheet, which she pulls back. By now, I'm starting to get an erection. She reaches down, holds my cock in her hand and begins to suck it. As soon as I fully erect, she straddles my body and slips me inside her. She starts rocking and moaning and soon her big saggy breasts are swinging back and forth. She feels amazing. In a couple of minutes she cums hard and then I do the same, with a great big, moaning orgasm. I hadn't had one like that in years.

The next morning it's a bit awkward during breakfast. Neither of us knows what to say. But I notice my sister is still wearing just her t-shirt as she makes breakfast. I feel myself stirring again. As we begin to clean up, she bends over at one point and I reach over and caress her ass cheeks under her shirt. She turns and smiles and I'm quickly behind her, pulling down my drawers and point my cock at her rear. She bends over the sink and I'm in her again. We fuck hard and both cum again, and again, it feels absolutely amazing.

Today, I go visit my sister about twice a month. My wife thinks it's so nice that I go over to help her since she's a widow and could use a man to help out with things. Little does she know we fuck like crazy when I'm staying with her.
