Pounding

 

You gasp in pleasure, your ass full of thick cock.  Feeling your wife's boyfriends balls slapping your taint, just makes it feel that much better...  You spread your ass more with your hands.  You want that cum filling your back hole until it runs down your pussy and legs...

 

No wait, you didn't want this...

 

Your new breasts sway in time to his cock pounding into you, your nipples hard as diamonds and big around as dimes.  They started so small, but seem to be growing so fast now... as each pump into your ass almost makes them seem bigger...

 

Make him stop I don't want to be a girl...

 

His strokes become faster, you know what's about to happen... his cock throbs inside you and you feel the hot cum pour inside your ass.  You cry out in pleasure as your new pussy spasms with it's first girl cum.  You hear your high pitched scream of joy...  It won't be the last.

 

Eyes wide, you try to crawl away...

 

Your wife kisses on your ass cheeks, then licks your now ready pussy, sending spikes of pleasure through your body, making you stop.  She takes her boyfriends cock, cleans it well, and guides it to your waiting cunt.  Spreading the lips of your pussy, your wife smiles... "Now honey, when he cums in your pussy, you will forever be our little slave breeder.  You will have our children for us." 

 

You try to struggle, you don't want to be their breeder... Do you?

 

She turns your head to face hers and you both kiss... and you lose yourself, melting into her lips...  He starts pumping deep into your pussy, all doubt leaving your mind with each thrust....
