Naughty, Dirty Fun

I was at my sister's place for a weekend of golf. Thursday night we grilled steaks and drank wine together talking about things in general. Her longtime boyfriend Tom had passed away just a few months prior. I avoided bringing his name up, but she couldn't stop talking about him. The more she drank, the more she opened up about their relationship going as far as describing some of their intimate secrets. "I really miss him that way."
"So, I take you haven't found anyone new?"
"No. It sucks. I've never been so horny."
It was a bit awkward. I was actually shocked that she didn't try something on me that night. We were no strangers to in cest. Her with dad, me with my mom. We also had done some naughty things when we were just kids. As children we did a little show and feel one afternoon. She saw my wiener and she showed me her bare pussy. We also did some dry humping after she had just gone through puberty. I knew what her bush looked like. So, I was waiting for her to either say something or try something sexual with me. Instead, she behaved. I remember almost wishing it had happened.
The next morning, we got up and drank coffee. Then we went to shower. I was headed to the hallway bath when her door opened. She stood there naked with a dirty grin. "Want to shower with me?" My eyes scanned her naked body. my cock began to grow.
"Uh, sure. Why not?"
I followed her into the bathroom. I started stripping while she adjusted the water to the right temperature. Then she stepped into the shower. I came in rock hard. Julie immediately reached for my boner. "Is that for me?"
"It sure is."
"I'm so glad you're here."
"MMMMMMMMMMMMMMMMMMMM, I wasn't expecting this."
"To be honest, I kind of wanted this."
"Oh, you naughty girl."
"I know, right?"
"I'll fuck your brains out."
"You have no idea how badly I need your cock."
The shower did not last that long. Long enough to wash ourselves then dry off. In her bed she laid back and spread wide open for me. I went to town eating her pussy. I took my time building her up. Then I proceeded to make that pussy squirt. I moved up as we both looked to watch my cock disappear into her beautiful black muff. "Look at that!"
"Oh my God! I'm fucking my sister!"
"OH YES! FUCK ME! FUCK YOUR SISTER!" There was a certain level of excitement in the air. Both of us wanted it so badly. It was the best pussy I ever had. I tried to go slow. But it was so very intense any movement made me want to shoot come. I literally stopped complete balls deep.
"What are you doing?"
"I can't help it. If I move, I'll come. Your pussy is just too good."
"Really? I do that to you?"
"Yes! Let me get settled down." Our lips met and we began kissing passionately. We made out for several minutes while my cock settled down. Then I began to move very slowly. My cock was throbbing inside her wet cunt.
"Just go ahead and shoot it in me. I'll make you hard again."
"You have such an effect on me."
"In cest is more exciting."
"It truly is. I want to come inside my sister's pussy."
I raised up on my arms and began thrusting deep and hard. To my surprise I had some stamina. Enough to pound her into a big squirt before I blasted probably the biggest load of come in my entire sex life. Both of us were in awe of our fun.
"I definitely want more of this."
"Me too. But we have to get to the golf course for our tee time. Maybe later?"
"Not maybe. Try for certain later. I want more cock tonight."
That night we fucked like porn stars. Every position you could think of. She had a chair in her bedroom. She rode me on that chair for almost two straight hours. The next day I was supposed to go home but I stayed so we could continue fucking. We made plans to get together at my place the following weekend. When she arrived, she took me straight to bed where we spent four hours fucking. Sometimes, being naughty is very nice. Being able to subdue your conscience is awesome.
