I have to tell someone this dirty secret that I have been keeping for almost three months now. My Girlfriend of three years has really been acting like a bitch lately, withholding sex and starting petty arguments with me over nonesense. One day while we were having one of these arguments, I decided to go out with the guys and club. Imagine my suprise when I bump into her younger sister who just turned 21. We talked then parted ways as she headed for the bar and I headed for the dance floor sense I never drink. After a few beers, she joins me on the dance floor and we danced together the whole night. Two nights later, my girlfriend is still not talking to me but won't say why because "I should just know." Anyways I get a call from her sister who got my number my girlfriends cell. She wants to go out dancing again but I shoot her down saying I was too tired and would be going to bed early. Two hours later I get a knock on my apartment door and it's the little sister!
She doesn't wait to be let in and pushes me aside jabbering about how my girlfriend and her got into this big argument and how I had to call and talk with her about it. I refused since she wasn't taking my calls either and suggested that they work things out between them tomorrow. The little sister refuses to leave saying she would rather sleep on my couch. I let her feeling sorry for her. As I walk towards my room to get back in the bed, the little sister grabs my arm and goes "You know we could do something to really piss her off." I play dumb, but the thought had already crossed my sex deprived mind and my dick immediately stood to attention. She noticed my hard on and giggled saying she was only joking. Tired of being teased I grabbed her by the hips and spun her around, pressing my hard dick against her ass. She moans and spreads her legs. If it wasn't for her pajamas, I would have slid right into her ass. Without exchanging words we both raced to get naked. I have always wanted to fuck her. She was not as stacked in the chest area as her sister, but she had a firmer ass and sexier lips in my opinion. Plus she lacked the attitude her sister had which was a relief.
As soon as my dick was loose from my boxers, she caught it in her mouth sucking viciously to the point that my toes curled and I had to sit down on the edge of the bed. Her sister never volunteered to give head and I usually had to beg her for it. I grabbed a hand full of her hair and started to thrust in her mouth. She gladly opened up and tried to suck all of my thick nine inch dick. After a good fifteen minutes of gagging the shit out of her throat I was ready to pound her tight pussy. Her sister always thought she was a lesbian, but the minute she spread her legs I knew I wasn't the first guy to enter that hole. She was still tight as hell, but by no means was she virgin. I put her legs up on my shoulders and plunged deep into her wet pussy. She was moaning and squirming, trying to slow my stroke with her hands. "Take this dick," I commanded her, as she keep repeating "Fuck me like you fuck Nikki (Her sister)." As her legs started to quiver for the first time I slowed my pace and turned her to her side. Not ready to cum yet, I would go deep in her stomach then pull out slow while her vagina would convulge and squeeze my dick. I slapped her ass at will, until it blushed red. She was begging me to keep spanking her saying it turned her on more. Finally we switched to doggy style and I grabbed her hair pulling her head back and galloping in her pussy. The sound of my balls slapping against her bottom was so loud my neighbors were starting to beat on the wall. I sped up as I could feel myself about to release all the cum I had been holding since her sister and I started arguing. She was to the point where she was begging me to finish. With a loud growl I gripped her by the waist and gave three hard long thrust in her pussy. She almost lost her balance and grabbed the bed post to sturdy herself. Without warning I pushed her head down, pulled out and started to spill a gigantic sized load of cum on her back and ass. She remained there bent over shaking her ass as the last few drops of cum splashed across the small of her back and seeped down her ass crack. Completely exhuasted I collapsed on the bed as she begain looking for a towel to take in the shower. Once she was washed she came back in the room and we layed together realizeing what we had done. Paranoid that this would crush her sister she has made me promise never to tell anyone, but I have to let someone know. She was the best piece of ass I have ever had!
Now when we see each other it is kind of ackward and she avoids me like the plague. My girlfriend and I have since worked out our problems and are considering moving in together. But everytime I fuck her I think of her sister and how tight and wet she was that night. I have to find away to stick my dick in that pussy again........
