Costume Gun: Unintended

 

I swear none of this was planned. I didn't even know what the ray-gun did when I found it. I mean how could I have ever guessed that it was a costume gun? The whole idea of a cheap plastic toy that turns people into hollowed out skins is crazy. The idea didn't even occur to me until the flickering purple beam shot out on hit my sister. Of course I was horrorfird when I saw her crumple into nothing but an empty shell. I rushed to her only thinking that I had to help her but instead I'd slipped and fallen head first into the gapping hole that had opened in her back.

Next thing I knew I was "wearing" her. Her soft smooth skin had become my skin. My body was now seamlessly incased in her girlish form.

I'll admit I allowed my curiosity to get the better of me at that point. I was in the body of a beautiful woman and for a moment I forgot all about whose body I was in. All I could think about was how glorious her breasts felt under my hands and the aching heat between my legs. Only her boyfriend knocking on the door to pick her up for her date snapped me out of it and left me blushing as red as her dress.  Well, what else was I supposed to do after that? I could hardly tell him the truth, could I?

I was backed into corner and the only way forward seemed to be to play along and pretend to actually be her. 

Passing myself off as her wasn't too difficult as it turned out. The two of them had only been out together a couple of times so he didn't pick up on my occasional slips. What I hadn't counted on was how being around him all evening would make me feel. The wave of uncontrollable arousal that had overwhelmed me had receded but I could feel it threatening to return just from being near him. My eyes lingered on his broad shoulders and strong arms. His smile made my breath catch in my throat. And when he took my hand as he walked me home, so big and warm wrapped around mine, I thought my heart would burst out of my chest.

Before I knew it he was kissing me, worse, I was kissing him back! 

My head was spinning as he let me up for air. My breast were pressed against his chest. His hand squeezing my ass. 

"Do you want to come in?" I almost whimpered with the force of my need for him and the lustful look in his eyes was all the answer I needed.

I there wasn't much thought involved after that. We tumbled into my sister's bed to stain the sheets with our passion and the sweat of our bodies. 

He slipped away early the next morning and I eventually figured out how to restore the two of us to our proper forms. If my sister was aware of anything unusual she never gave any sign of it but I'll never forget that glorious night.

So you see I never intended to sleep with sister's boyfriend but I'm totally going to do it again!
