As I described the noises that I heard coming from the living room, Billy just started to tear up and Mary looked like she was about to throw up. Through all this Kim just watched their reactions trying to gauge what would happen next. I stopped the graphic description, and cut straight to the chase, I asked them how long this relationship had been happening. Both began stammering, sounds like words kept coming out of their moves, but nothing that one would call an actual word.
I waited a moment to see if they would regain their ability to speak and then stopped their misery. "Alright, let's try this again. We're not mad at either of you; we just want to figure out how this came about and what we plan on doing about it. So, Billy, how long have you and your sister been having sex?" With a deep breath and a very quiet answer he told me that it had only been the last few months. Okay, next question, "Mary, how did this all start?" Mary looked at me with huge eyes, you could tell that she was not expecting me to address her with a question, figuring that I'd let Billy do all the talking.
Again, I told them that their mother and I were not angry, we just wanted some answers. Hesitantly, Mary told us that it happened in March when we had taken a quick weekend trip to Baltimore and they were left home alone. A big storm had moved in through the night and had caused the big trees outside to smack the house with their branches. She was scared and asked Billy if she could sleep with him that night. In his stupor he raised the covers and allowed her in without remembering that he always slept nude. Now it was my wife's turn to surprise us by asking for more details, all of them. I think Mary was taken aback, but quickly realized that Kim was getting excited by her nipples trying to poke holes through her sundress. With a sly smile, she began to tell the whole story in very graphic, erotic detail.
This is Mary's account of her first time with Billy. (Told from Mary's point of view)
The storm had awoken me in the middle of the night. I hadn't heard it at first, but when the branches started to hit the house I was startled awake, and afraid that the tree was going to come right through the house. Normally storms don't bother me, but this was no ordinary storm and I knew that I wouldn't get back to sleep. I was scared. So, I did what I always did when I was little, I went to my big, strong, twin brother, my sworn protector. I knocked on his door, but heard no reply. So I went in and saw him sleeping like a big log in his bed.
Not wanting to just climb in, I gently prodded him until I got a mumbled "what?". I then told him that I was scared and asked if I could sleep with him tonight. He mumbled something else and lifted the covers just enough to allow me to slip into his bed. Instantly I felt safe. It was warm and cozy. He grunted something, rolled over and went back to sleep. The storm still raged outside, but I knew I would be alright. I awoke many hours later with his left arm draped over me and something poking me in the back.
I froze, when I realized what it was, but quickly started to wonder what it looked like. It felt like fire it was so hot, I knew right then that I wanted to touch it, if only for a second. I slowly moved my arm until I could bring my hand behind me. I stretched out my finger tips trying to find his erection, and then suddenly, there it was. It was so hard and soft at the same time and I could feel the heat emanating from it. Slowly I wrapped my fingers around it, and I could feel the power within it. My pussy was on fire as I slowly started to stroke it. The longer I touched it, the less I cared if he woke up. At that point I said "fuck it" and I rolled over to face him. My hand quickly resumed its last task.
He started to wake up asked what I was going on, I told him to shut up and enjoy it, because I certainly was. He weakly protested one or two more times and eventually gave up, his hormones getting the best of him. A hand job was all well and good for him, but my pussy was screaming for more, so I kicked off my panties and climbed on top of him. His eyes shot open and he tried to speak as he felt the heat of my pussy on his hard cock, but I shut him up by sticking my tongue down his throat. His eyes were still open in shock as I tongued his mouth and sank down on his cock in one slow motion.
The world stopped moving as I knew that however wrong this was, it felt amazingly right. When I hit bottom, I sucked in a breath and groaned into his mouth. Fuck did it feel good. Slowly I started to grind my clit against his pubic bone and I knew I wouldn't last long. Billy grabbed my ass with his strong hands and helped me to my first orgasm of the day. When it hit, it washed over me and I could feel the muscles in my cunt vibrate as the energy moved through my body. Billy just let me have my moment and then he started slow, long thrusts up into my body.
My body didn't have time to come down sufficiently from my first cum, so it just started right back in to a second one. This time, he didn't stop he continued to pump faster and faster. Now my orgasms had just blurred in to one long, continuous, body shaking event. I was barely aware of what was happening to me when I felt one powerful thrust into me and he let out an almost primal roar as his cock pulsed and pulsed inside me. I could almost feel his cum hitting my cervix over and over again. We both just collapsed barely able to breathe. I could feel his sperm leaking out of my well used and very happy cunt, and I didn't care. I had just had the best sex of my life and it was from my very own twin brother. Everything was perfect.
Fin (for now)
