My wife and I have been together for over 10 years. We love inviting her sister over to play cards and have a drink. Let's call her Sara.

Whenever Sara came over to play cards and have a drink, the more she drank, the more kinky and sexual things got. She always looked into my eyes when she was drunk. That "I want to fuck you" look.

She would often stick her tit out or walk around without panties in a miniskirt. I'd seen her naked many times before. She had a hell of a nice ass and the softest pussy.

On Friday, we played Cards Against Humanity and, of course, we drank. This time, my wife got incredibly drunk and started telling Sara about how she used to come to the bathroom at night to take a piss, "help" me pee, then masturbate me a bit, and then we'd bend her over and fuck her until I came inside her pussy.

Sara's eyes got huge. She told us that this was really turning her on and that she'd like to do the same with a guy someday. So we finish up and start cleaning up. (I mostly clean because my wife was so drunk.) My kitchen is pretty small, so I tried to squeeze past Sarah, and she shoves her ass in a short skirt with no panties right up my crotch. It really turns me on.

So we finished cleaning up and I put my wife to bed. Sarah decided to stay over. She put on a really sexy nightgown and went to the bedroom across the hall. I climbed into bed and fell asleep.

I woke up around 3:30 a.m. to take a piss, as usual. I'm standing there peeing, and then I hear the door behind me open. I feel someone reach over and grab my cock. I'm still peeing because I've had a lot to drink too. I finish peeing and, just like before, I start masturbating. The bathroom is dark and I can barely see. I'm a little hard, but I'm getting a little tired from the alcohol.

I turn around, grab her by the waist, and start pushing my cock into the person I thought was my wife. (They both have the same figure.) I keep thinking, "Damn, she's tight tonight." So I start thrusting and grab her breasts as she's bent over, and that's when I realize who I'm fucking. It's Sarah. She has a pierced nipple. I was about to pull out, but it felt so good. She was so tight and wet. With each thrust, she squirted a little. I wish my wife could do that. I was just orgasming her and felt the burning in my balls. I was about to come. I told Sarah I was about to come, and she told me to hold it. I continued until I came. One shot after another, just pumping her pussy full of cum. I was amazed at how long my orgasm lasted. She started to come too, squirting like a garden hose. I'd never had such a powerful orgasm in my life. I slowly pulled my cock out of her pussy, and my cum just gushed out. She was still incredibly horny. She told me to wash her. So I grabbed the toilet paper and prepared to wipe her, and she said, "No, with my mouth." I was surprised. She grabbed my head and pressed it against her pussy. I licked the cum off her pussy. It wasn't as bad as I thought. I was on my knees and licked her pussy, and she said she was coming. So I stuck my tongue into her pussy, and it was like someone turned on a garden hose. She started squirting her juices right into my mouth. She grabbed my head and held my mouth to her pussy. She told me to drink it all. And I did. It was so hot. My bathroom was a mess. Cum and her jizz splattered all over the floor. I simply grabbed a towel and started mopping the floor.

Finally, I dried the floor and stood up.

Standing there with my cock rock hard. Sarah looked at it and said, "Looks like you're not finished yet." She turned around and leaned in again. "Eat my ass," she said. My wife never let me explore her asshole. I plunged inside her with little licks and prods. It drove her crazy. Then she told me to shove my cock up her ass. I couldn't believe what a dirty little slut she was. I rammed my cock up my ass. God, it felt so good. After about 15 thrusts, I felt my balls tighten again. I told her I was about to come. She told me to come in her asshole. Three more thrusts, and I shot another huge load inside her. I pulled my cock out, and she turned around and thanked me for fulfilling her fantasy. I smiled and slapped her ass. I went to sleep and passed out. The next morning, Sarah said she had forced cum out of her ass and was masturbating with my cum when she woke up. This is my first post. Sorry, it was a long story. We fucked often.
