“Rick, Dwayne and I are going to the beach for a few days and want to know if you and Caroline would like to ride with us” my sister Jen asked me. Jen was a couple of years older than I, and we had always been close. She had been married to Dwayne for two years. Caroline and I had been married for one year. I told her I would talk to Caroline and call her back.
Caroline thought it would be a great idea and so we packed the car Friday and took off, planning to get a hotel on the way. Everywhere we stopped, there were no vacancies, until finally we found a hotel that had one room, but it just had one bed, a king size bed. We decided that would work as Jen and Caroline were both rather petite, about 5’4, 120 pounds and Dwayne was 5’8” and 140 pounds and I was even 6’ and 170 pounds.
We all had a great dinner, talked some, then went to the room and showered and retired to bed. The sleeping arrangements were pretty simple, Dwayne, Jen, Caroline, and me. Soon we were fast asleep. But sometime during the night Caroline began to cough and got out of bed and went to sleep on the lounge chair by the window, on Dwayne’s side of the bed. Later Jen somehow ended up spooned up against me and I was hugging her as I thought Caroline had returned to bed, and began to massage her breast. My cock began to harden and I pressed it against her butt. The female next to me pressed back, and I moved some to get my cock under her nightshirt and onto her pussy lips. My cock could feel the damp pussy and I continued to quietly rub my cock over the pussy lips, moving it along the edge of the panties.
I moved my hand down to rub her cunt and soon my hand was wet with pussy juice. I was pushing my cock against her labia, and soon I took my hand and moved her panties to the side and had my cock at the entrance to her pussy. She shifted to make entrance easier, and we both pushed and I was in. We quietly pushed in and out, my balls gently slapping against her butt. Then she moved away from me, raised up, and to my horror, I saw that I had been fucking my sister Jen. She put her finger on my lips and said, “Rick, its o.k. I have wanted this so long. Please, I want to continue” and she looked at her husband asleep a few inches away from us, and then at my wife asleep in the chair and then crawled on top of me and began to ride my cock, up and down. I was sucking on my sister's tits as she rode my cock.
“Jen, I’m going to cum and I know you are not on birth control” I said. “It’s o.k., pump your seed deep into me. It is your baby I want anyway.” And with that I shot rope after rope of semen deep into my sister’s belly and my finger and cock together worked her clitoris to a climax, which she worked hard to muffle.
She climbed off me, and moved next to Dwayne, but not before she said, “brother, this was the first time, but please, let us make many more times like this.”
The next morning Caroline’s cough was much better, we got in the car and continued our trip to Florida and the beaches. We checked into our hotel and got adjoining rooms, with connecting door. We spent the next two days on the beach.
On the third day, Dwayne wanted to go golfing, but I do not golf, but I insisted that he go. In the meantime, Caroline had run into a classmate from highschool and I told her to spend some time with her, that my sister and I could find something to do. As soon and Dwayne and Caroline left, Jen and I headed to Jen’s room. We stripped and jumped on the bed. Jen’s body was absolutely gorgeous, with her 34c tits that I just had to suck. Then I began to kiss her stomach and then down to navel, south to her pussy. She told me I was doing something no one else had ever done. I kissed around her pussy, on her thighs, I could tell she was getting hot. I blew on her vagina, licked on labia, and put my tongue on her clit. She jumped and I could tell she was close to orgasm. I then stuck my tongue into her pussy opening as far as I could, and Jen moaned, then I began to suck on her clit—Jen let loose with a flood of fluid and began to moan and begged me fuck her. I climbed on her and she grabbed my cock and put it in her pussy and we began to move wildly. Up and down, up and down, the bed was rocking, and now Jen was cumming again, crying, oh god, I’m cumming and I moistened a finger in her pussy and put it up her anus and this drove her into a maximum orgasm. She went limp, and said “Rick, I have never been fucked like that, and that finger up the ass, never had that, it was the straw that broke the camel’s back, or opened the flood gates, or whatever, it gave me the best orgasm I have ever had.”
That afternoon we fucked, sucked, and fucked some more. Jen said she was sure she would go home pregnant after this day. Our spouses came home and found us on the veranda with ice tea and asked us about our day. We told them we were exhausted, that we had walked for miles on the beach.
After the beach trip Jen and I get together to fuck and I like to go visit our baby son. He is quite the handsome guy. Dwayne is so proud of him.
Jen and I continue to fuck at least once a month. She is pregnant again with our child. She and Dwayne are so happy, but I feel sort of guilty about fucking her because he is such a nice guy. However, my wife is a good fuck, but my sister Jen is a great fuck and we both hope to continue our affair.
