Kelly is my baby sister. She is only 17... but then again, so am I. We are twins and I'm only 30 seconds older than her. My name is Matt. There's something you should know about Kelly, she is a total babe! She weighs about 135 pounds and is 5'5". She has long, sandy blond hair and deep blue eyes. Her tits are not small but they aren't large either, I'd say B cup (somewhere around there). She has a large ass and she sure as hell knows it. I have always loved seeing her and she has such a gorgeous smile that lights up the room.
I started getting hard at the thought of Kelly when I was 16. We were at the pool and she just bought this tight black bikini that flaunted everything. Watching her come out of that water and walk towards me, ass bouncing and boobs jiggling, I had to leave the room. She was just so hot. Ever since then could jerk off to the thought of her. I know it might seem wrong, but it felt right. I have been doing that once or twice a week now.
My parents left for work that day so Kelly and I were home alone. We have been out of school for about a week and a half. It's hard to think that this upcoming year will be our last year together... I have been with her my whole life and I don't know what I would do without her.
"Matt." she says quietly, but I am lost in my thoughts.
"Earth to Matt.... Hello??"
"huh? Did you say something?" I said surprised. I didn't know she was talking to me.
"What do you want to do today? It's lunch time and I'm hungry and bored."
"Well why don't we order some pizza and watch a movie?" I said to her
"Ok! I'll find the phone and you pick out a movie! You always have good ideas!" She said to me as she walked passed me. She was still in her pajamas and she wasn't wearing a bra. You could see her nipples through her skin tight white shirt. The smell of her as she walked by was intoxicating. It smelled like vanilla, which was her favorite kind of lotion to use. As she walked away I turned to follow her with my eyes. Her shorts weren't the most covering thing in the world. Her butt cheeks peaked out right on the edges.
She came back into the room with the phone and leaned over me to the get into the drawer next to my legs. I glanced down her shirt at her small round tits. A thought rushed through my mind of me grabbing them and just playing with them. I could never do that though! I was her brother... it would be wrong.
"Are you going to sit there and watch me struggle or are you going to help me?" she said to me as she stared into my eyes
"Oh, sorry. What are you looking for?"
"I can't find the menu. It has the number on it for the pizza place."
I reached down to help and my hand brushed against her small chest. I wanted to say that I was sorry, but she didn't notice. I turned around to keep myself from looking again. The only problem was, her huge ass was right there. I could feel myself getting hard. I got up and ran to the bathroom before she could notice.
"Matt! Where did you go?!" She called down the hall.
"I'm.. uh... in here! But don't come in!" I called to her from my bedroom. I was trying to get rid of my boner before she could notice. All of a sudden I hear the door knob turn. I frantically looked for something to cover up myself with. Right then she walked in.
"Oh my God!! What are you doing?!" She screamed. My face turned bright red and I covered up my erect penis with my hands as best as I could. That didn't really work considering I was about 8". "Holy shit! Get out!" I screamed, but I didn't really want her to leave. She started walking towards me, just staring at my penis like it was something new to her. "Yours is so much bigger than my boyfriend's." She said to me. "I know this might be weird, but can I touch it?" The look on her face was so innocent. It was so sweet and delicate. "Uhh.... sure. But you can't tell anyone!" I made her promise.
She leaned down to look at it. She gently wrapped her soft, warm hands around it. I didn't mean to, but I let out a soft moan. "Oh!" was all she said. She squeezed it a little and the moan got a little louder. I have been imagining this moment for a while, but I never thought it would be real. Kelly then started to rub up and down while gently licking the head. I wanted to say something, it just felt so good that I didn't want her to stop.
Then she wrapped her mouth around my pink head. She shoved my penis deeper down her throat, squeezing it lightly as she sucks. "Kelly, what are you doing? This isn't right!" I said quietly.
"Just shut up and let me finish." I have never seen her so demanding before, and I have to admit, it was kind of hot! I put my hands on her head as she started sucking faster. My hips were moving with her sucking motion, and soon I slammed her head down as far as it would go. I let out a long load into her mouth as she gently squeezed my dick. When I let go she looked at me and smiled as she swallowed it all.
She climbed on top of me and grabbed my hair. She opened her mouth and kissed me. I felt her tongue exploring my mouth. So I grabbed her and kissed her passionately. I could taste my own cum on her sweet cherry flavored lips. As we kissed I started to take off her shirt.
"Matt, let's wait. The pizza will be here soon." She said as she gave me a little peck on the lips. She gracefully climbed off my lap and headed down the hall. I was sitting there speechless, totally dumbfounded. I quickly grabbed my boxers and put them back on. When I walked into the hall her scent still lingered. As I entered the kitchen Kelly was standing there in only her pajama shirt, eating a slice of cheese pizza. She looked at me and smiled.
"Here we go again." I said as I smiled back to her
