My Sister Kelly

I was home only, my mom was at work and my sister, and Kelly, my sister, had not come home yet from collage for the summer. I was in my room laying on my bed naked jacking off to a magazine. I never heard my sister pull up into the driveway and come into the house.

Kelly came walking into my room; “Hey Eric can you….” Her eyes bugged out as she walked in on me. “Shit Eric, can’t you lock your door when you are going to jack-off!” I was so embarrassed; I covered my swollen shaft with the magazine. “Damn it Kelly, can’t you knock” I yelled back at her. She just stood there looking at me with her hands on hips. Kelly is an absolute hot body knock out. She is 5’3”, 95 lbs., brown eyes, brownish-red hair and beautiful, natural 34D tits. If it weren’t for the fact she was my sister, I would think about her and jack-off her to every damn day.

She was wearing jean shorts and a T-shirt, I thought I could see her nipples protruding through her shirt. She walked right over to the bed and grabbed the magazine out of my hand; by now my hard on was gone. I covered up my limp cock with my hands, I tried to get up to get some clothes but Kelly yelled at me and told me to lay there or she would tell mom what I had been doing. She flipped through the magazine looking at the pictures of all the large breasted women. “So is that all you guys can do, stroke your cocks and blow your load all over yourselves to a bunch of pictures?” “Well Eric, do you do this all the time?” I started to answer, “No, I just was feeling kinda horny sis.”

“Bull shit, I bet you jack yourself off every fucking day!” She through the magazine back at me and told me to show her who I was stroking myself off to or else she would tell mom. With out even thinking, I grabbed the magazine and flipped through to show her which one; my cock was fully exposed, in all its limpness. I glanced up and saw her take a quick look at my cock. I handed it back to her, but I did not cover myself back up.

She looked at it and said, “So were you thinking of fucking her?” “Well of course I was Kelly.” “Hmmm, nothing else Eric?” I shook my head no; I didn’t understand what she meant. “You are so full of shit. I know exactly what you were thinking. You were thinking about her sucking your cock. You were thinking about blowing your load into her mouth, weren’t you?” I just looked at her in shock, I could not believe my sister was saying these things to me. “I’ll bet you were thinking about either fucking her big tits, cumming all over them or blowing your thick cum all over her tits and tongue, watching her lick your cum off and swallowing it all!” I tried to answer but she cut me. “Don’t even bull shit me dear brother. I know guys, you all think alike. You want to have your cocks sucked, you want to blow your loads all over women’s tits and in their mouths.” My cock was starting to move, coming to life hearing her talk like this.

Then she stepped back and threw the magazine down to the ground. “Would you jack off for me?” My jaw dropped, “No way, you are my sister!” “So what? Don’t you think I have a nice body?” She started to slowly rub her hands up her hips to her beautiful tits; she squeezed them and turned around bending over a bit to grab her luscious ass. She turned around and looked at me again.

“Well yeah you have a great body but…” With that she grabbed the bottom of her T-shirt and began to pull it up, slowly. My cock started to get rock hard, real quick. She pulled her shirt up a couple of inches, revealing her sexy abdomen, nice and firm. Kelly looked at me and said, “Would you jack off to me now?” I said no. She pulled her shirt up to just under her tits, I could see she had no bra on! She got a sexy smile and asked again if I would jack off to her. I suddenly realized her game, I thought, so I smiled back and said ‘I don’t think so’. My sister then pulled her shirt half way up her magnificent tits. Her areolas are large with nice big nipples. She said “how about now, dear brother?” I responded “I am not sure dear sister”. She looked at my cock, which was now rock hard. “Are you sure Eric, your nice hard shaft is telling me otherwise”. She smiled and then pulled her shirt right over her tits, leaving it just above them. “Oh, yeah Kelly. I could definitely blow my load for you now.”

My sister then asked me if I wanted her to take her shirt off the rest of the way, I said sure. She said fine, she would take it off the rest of the way if I admitted to her what I was really thinking when I was jacking off. I told her she was right, I was thinking about the woman in the pictures dropping to her knees and sucking my cock. I was thinking about cuming in her mouth and all over tits.
