How My Deviant Life Started

... &#034Hey!&#034 Kelly said. &#034Relax! I ain't going to say anything..........IF....&#034 What a relief! Wait! What? &#034What do you mean &#034IF&#034?? I said. She looked at my coyly....and with her best &#034Daddy's Little Girl&#034 voice said, &#034If you let me watch you do it!&#034 I was floored. My head was spinning at a million miles an hour. I said &#034But, your my s****r, and, and, you already have watched me, and, and, your my fucking s****r!!&#034 She tells me to relax, and that it's ok. She sits back in the chair and pouts, folding her arms across her chest. That's when I notice, for the first time, that all she is wearing is one of my old white tee shirts. Worn and almost in tatters, I can see her two huge nipples poking up under it. It is short, so short, I can also see that it barley covers her, well, it doesn't. I can tell she isn't wearing any panties, and I have a clear shot of her vagina. As I laid there talking to Kelly, I was trying so hard not to stare at her crotch. As I did, my cock would throb harder and harder. I soon realized that, at some point, our conversation turned into a negotiation! Damn dick took over! LOL I soon realized that in exchange for her silence, every time that I jerked off, I would not stop when she would sneak up to my door to watch. This was so strange to me. Talking to my s****r, which, ordinarily wasn't any big deal, but now, which a raging hard-on and an overwhelming desire to blow a load all over, was foreign to me! I was ...

... liking it, liking it very much! With negotiations done, Kelly got up, she had a huge grin on her face, turned to walk out and stopped, &#034I have to pee again, so don't start until you hear me flush!&#034 she giggled and with that, bounced out of the room, lifting her shirt up over her ass as she passed thru my door. I threw my sheets back and rolled onto my back, cock was pointing up, throbbing and twitching, I spit into my hand and wrapped it around my swollen member. I was surprised at how hot it was. I gave it a good hard squeeze in an effort to quell the impending explosion. I heard the toilet flush and waited a few seconds before I started my strokes. Knowing she was watching was tremendously exciting. I started my hand up and down the shaft, squeezing the base hard so my cock would swell even more. I looked at the doorway and could see my s****r looking in, fixated on my cock, glazed eyes wide open, mouth open in a heavy pant. I started to stroke faster, making my balls slap against me. I lifted my ass up a bit and spread my legs wide. Staring at Kelly, I could see she was rubbing her pussy feverishly. I could hear how wet she was. That was all it took, a huge rope of cum shot out the tip of my dick, it had to shoot a few feet in the air, I groaned and another stream of thick, white goo shot out. I heard a whimper, and saw the pleasure on Kelly's face. She was cumming too. I shot out a few more times, all of it landing on my belly and chest. My cock still hard. Still ...
