The Slut Gene

 

You can hear her in her bedroom next door fucking her latest boyfriend you cant help but feel turned on by the naughty sounds you slowly slip your hand into your panties and start to play with your pussy you cant believe your getting off to the sounds of your sister getting fucked but pretty soon it will be you taking a big meaty cock and making such wonderful sounds.

It had taken years but finally you had discovered why your older sister was so sexy, confident and slutty after countless months analysing samples you had stole from her you had isolated what you called the S Gene or as some would say the slut gene, now with this new discovery it would be a simple task to splice the S gene into your own DNA.

If your theory was correct it would make you sexier and far more confident you would finally get to lose your virginity and make the same sexy sounds you hear emanating from your sisters bedroom each night.

It was with great trepidation that you went ahead with your plan to splice the missing slut gene into your own DNA you weren’t entirely sure of its effects but in science there are always risks.

You dropped to your knees in agony as the slut gene began changing your body making it hotter sluttier the pain was soon replaced with pleasure as your hair turned blonde and took on a health sheen as it grew longer and healthier, pressure built up on your chest as your tits expanded to large 32DD orbs you marvelled at your legs as they became lengthier and well toned the rest of your body followed suite as all blemishes disappeared from your skin. New thoughts flooded your mind as you gained an instinctive knowledge of how to be a total slut you pussy moistened at your new found instinctive slutty knowledge, and with that the Slut Gene had done its work where a prissy shy virgin once was now remained a slutty bitch who loved the thought of dirty unprotected sex especially if it was with your sisters man behind her back  

You felt so hot and horny as you admired your new body in the bedroom mirror doing a little pose, god you needed a cock in your slutty pussy you couldn’t fight it the urge to fuck was now permanently and irreversibly coded into your very DNA, pulling out your sisters mobile you had stolen you smiled a wicked smile as your manicured hands text Ryan your sisters boyfriend inviting him over for a booty call.

if all went to plan within the hour you would no longer be a virgin and your slutty hunger would be sated for the time being.

You couldn’t believe how good it felt when Ryan thrust into your pussy for the first time you body wanted nothing more than to be taken and used by a man you were a slut you couldn’t help it, it was in your Genes now and you loved every second of this fuck, no longer would you be listening to the sounds of hot sex you would be making them sounds the thought of it just made you tingle all over being a slut was the best.
