A powder box

Holding up a small box, Sharon pops it open and blows on it and something flies into your face, coughing you step back as it burns a little in your eyes, " now I did not really want to waste this on a nobody like you but I have a feeling I will need you on my side if I want this job and boy do I need this job, now then kneel for your mistress". Blinking you only feel a burning inside of your body and a throbbing in your head, before Sharon slaps you in the face, " did I not say kneel ".

Turning to Sharon your hand shoots out and grabs her by the neck and lifts her of the ground, completely unable to speak or barely breath Sharon is in shock at your actions, out of the three other men she has used the powder on before, they have become her instant slaves so she cannot understand what is happening. Different things flash through her mind as she struggles in your grip as all the hate and rage you have for what she has done comes rushing out. " I am not yours bitch you are mine now", making it a command as well as a statement.

After that statement Sharon realises in horror she can see your body is increasing in size and your clothing is straining to contain your new frame now and no sooner has she noticed this then your shirt rips along its sleeves, down your back along your chest and your pants just self destruct. Now she thinks the powder has done what Professor Nails set out to do in the beginning and she is partially correct the powder has reacted with the changes the serum already has made to your body and as the two compete it has caused these changes including a rather bad time for the Sharon.

Reaching forward with your free hand you rip open her shirt exposing her 32dd breasts which are contained in a lacey pink bra which you destroy with a simple tug, followed by her pants been completely ripped off her body as well, her matching pink panties suffer the same fate as you rip them off too and shove them in to her surprised mouth after realising your grip on her throat. Now tearing off the remains of your clothing Sharon can see the size of your cock and her eyes go wide as it has also suffered a change as well.

Already dripping with pre cum your cock is now a massive size and Sharon falls on her ass as she tries to move away from you. With her legs spread open before you Sharon is fully exposed in all her glory and seeing this causes your cock to spasm spraying pre cum all over Sharon which, with the effects of your earlier command causes large amounts of the serum inside her body to be flushed out of her body.

Grabbing Sharon by her hips you lift her up off the ground and lower her on to your enlarged cock. Screaming at the intrusion of your cock inside of her the sound is muffled by the panties she has yet to remove form her mouth and can only struggle as she feels the cock move deeper inside of her. Pulling Sharon further on to your cock it reaches her cervix and as it progress deeper Sharon is no longer struggling against you but trying to make it fit further in to her as the prototype formula has now all been expelled from her body and all that is left is the desire to be yours.

Pumping your cock in to her it finally reaches Sharon's womb and if one was to see your cock it is not even two thirds of the way in her yet, smashing past her wombs entrance Sharon can only scream again as your cock slams in to her wombs walls over and over before you begin to cum inside of her.

Holding Sharon tight as you empty your grape fruit sized balls in to her womb and Sharon moans as she feels her belly begin to expand to contain the huge amounts of seaman you are pumping in to her right now. Moving her over to her desk you put her down on top of it and pull your cock out of her letting a large amount of cum to run out of her pussy making her look only a few months pregnant instead of a full nine months.

In a voice that does not sound like your you talk to Sharon. " Tell me how many others are in this house and how many you have turned to your side with this stuff you are using", smiling to you as she rubs her inflated belly, " of course master in the house at the moment apart from Nikki you meet earlier only three others are here, I have in total turned only six girls to my side as it is very hard for me to make more of the formula without access to the compounds, materials and equipment, I have had to water down what I have of the formula a lot after using it on Nikki, but with the powder I have turned three men in to slaves, of the girls two are not here now the others are up stairs in their rooms waiting for my command to come out".

Now if this had been before you got dosed with her powder it would have not caused much of an issue other then you heading up stiars to issues a few commands, but afterwards it is different, you cock is now a rather horrifying 20+ inches long and your balls are the size of grape fruits also you have grown rather large in all areas of the body as well. Standing 7ft tall now with muscles to match you are having trouble focusing on anything other then sex at the moment.
