I woke up with last night's memories of finally fucking Cousin Jessie still fresh in my mind, and my morning wood poking at her ass under my pajama shorts. I got up out of bed and walked out into the hallway, and heard my sister Jen and Jessie's brother Ray playing on Matt's Xbox. Or were they? I knew from what I could hear that Grandma and Grandpa were going at it in their room, but I went over to check on my brother and cousin on the game room. What I saw when I opened the door was a sight that I would never forget.
My 19-year-old sister Jen was lying naked on the sofa in front of the TV with the Xbox on pause, and my cousin Ray was eating her out. My sister's pleasure was evident as her brown eyes twinkled while she threw back her head of black hair. I stared in disbelief for a few moments, and I heard Jessie stirring in our room. A few moments later, she stood next to me, also staring at what my sister and her brother were doing. I stepped forward, and asked Ray and Jen if this was a new development. Ray said, "as a matter of fact, it is. We heard some commotion outside yesterday, and saw you guys going at it on the swing set. It made us so hot that we had to tape it to use as a reference for our relationship."
Infuriated, I replied, "I thought you two were out fishing or shopping or whatever!"
Ray giggled, and said, "we thought so, too, but we fell asleep and they left for the outings without us. We just stayed up here and looked out the window the whole time. Would you like to join us?"
"Well, I guess it can't hurt to chime in, since you're in on the secret." I said, and Jessie and I tossed off our pajamas. We hopped up on the bed, and I immediately started thrusting my tongue in and out of her pussy. I wanted to rush her first orgasm so that the two of us could have our second fuck at the same time that Ray and Jen have their first one. Within two minutes, both Jessie and my sister were crying out in pleasure, and us guys were ready to kick it up a notch.
"Ummm, Ken," Ray said suddenly, "I don't know how to properly pop Jen's cherry since this is my first time. Can you do it for me?"
I couldn't believe what I had just heard. I had been requested to not only fuck my own sister, but to be her FIRST fuck. I looked over at Jen, expecting her to protest, only to see her nodding in approval. She cupped a hand around one of her boobs, and shook it while flashing me her bright smile on the beautiful, tanned Brazilian face she got from Mom, and I couldn't restrain myself. I told Ray to get ready to fuck Jessie as I positioned my cock near the forbidden chasm of my own sister's pussy, and lifted her legs over my shoulders. We were both going to be one with our own sisters; a nightmare and an adventure all at once! I give the countdown for penetration, "3-2-1, LET'S FUCK!!"
