My name is Jim and this is the story about me and my younger sister Debi. She's 2 years younger than me so we were pretty close growing up.
It started when Debi called me to come and visit. Her divorce had been final since December and it was now June and she wanted to get out of the city for a little vacation. I have a pool and lived about 4 hours south of her so she called to see if she could come visit for the weekend. She said a little fun in the sun and relaxation would help her feel better. I knew she was upset because she had dated a couple of jerks since her divorce was over. I knew what she was going through. I have been divorced for about 2 years and struggled finding someone worthwhile to date.
Debi arrived at about 6:00 pm Friday night. I met her with a drink gave her a big hug and asked her what she wanted to do. She said she wanted to drink and hang out by the pool. I showed her to my guest room and she said she would change and be right out. So I went out to the pool and waited. She came out in this tight little pink bikini that wasn't a thong but was on the small side. I had always enjoyed checking out my sisters ass in a bikini as we grew up.
So as we were hanging out getting drunk she started to tell about how things went wrong with her husband and how the guys she dated after her divorce were just jerks and she started crying. I got up and went over to her and gave her a hug and a kiss on the cheek.
She said "Guys must think I'm useless and ugly because they were just mean and degrading to me."
I said "Debi, you're beautiful and that any guy would be crazy not to want you."
She looked up at me and said "Would you want me, I mean if I wasn't your sister."
I told her "I think you're very hot and I would if you weren't my sister."
We were still in a hug when she unexpectedly pulled me toward her and kissed me on the lips sliding her tongue into my mouth.
I leaned back and said "What are you doing?"
Debi looked me right in the eyes and said "Let's say were aren't brother and sister tonight. I know how you've checked me out."
She leaned forward and kissed me again this time putting her hand directly on my crotch. She said "You can't deny me Jim, your cock is rock hard. Pretend I'm your hot date and we're back at your house ready for sex."
With that she stood up, grabbed my hand and pulled me to have me follow her. She went directly to my bedroom and as she turned her bikini top fell off. I had always liked looking at her 32 B cup tits. She grabbed my hand and put it right on her tit and said "Jim, I need this so bad. Fuck me like I was your hot girlfriend."
So I grabbed her bikini bottoms and yanked them down and pushed her down on the bed. Now completely naked, my sister was face down on my bed and I was staring at her ass. I pulled my trunks down and climbed on the bed. I laid down on top of her with my cock resting in between her ass cheeks. I leaned up and whispered in her ear.
I said "I'm not going to fuck you as my hot girlfriend, I'm gonna fuck you as my hot sister that wants her brothers cock."
She got a huge grin on her face as I leaned back and put the tip of my cock at her pussy lips. She was so wet. I could see it. I figured she was so wet so I just thrusted, shoving my cock all the way in in one stroke. She let out a very loud moan followed by an oh my god. Then I just started pumping.
