No Longer Useless

"So this is how he's... well, she's been getting double doses of fresh cum."

 

"Apparently 'she' discovered a new ability to suck her own clit.  As he's fucked, he ingests his own cum as it leaks from his clit.  Then when his, well her, partner cums, it's another fresh load.  It's advanced her transformation 3fold.  At this point it's permanent.  I'm sorry sir.  I know you wanted more for your son."

 

"And you say his... her craving for semen has increased as well?"

 

"Yes sir.  We caught her giving the staff blowjobs multiple times.  She's developed an uncanny ability to suck a man dry, so to speak.  That's why we ended up locking her up in her room.  But as you can see, where there is a will, there is a way..."

 

The men hear a gurgling, and watch as the former male's balls swell a bit, then shrink down as the soon to be girls clit releases a load of cum into her mouth and she swallows.  At the same time, the man fucking her ass also cums, filling her from another end.

 

The effect is almost immediate... swelling of the hips and ass, body shrinks down.  Breasts swell even larger than before.  For now, the clit, as they are calling it, remains long.  Soon it will shrink down to nothing but a cunt.

 

"Give him all the cum he wants, Dr."

 

"But sir... that will cause... well, nymphomania!  He..she won't be able to stop herself!  She'll transform completely, there will be no going back!"

 

"I know.  He's been useless for years.  Now he can earn room and board by performing as a slut at parties for me.  And he can pleasure his old man now and then.  After all, at this point his original DNA is almost gone.  Once he gets his cum booster, that DNA will be gone.  He won't be my son any longer.  Just a whore to be used, a cum receptacle."

 

The man walks out of the room and closes the door, with the Dr. looking on in shock.  Over the speakers he hears a moan escaping the soon to be slut's lips, and he unzips his pants, and opens the door.

 

"Well, at least there's one benefit to all this..." the Dr. says as he slides his cock into the slut's ass.  She moans loudly as she expertly milks him.

 

Tomorrow, the Dr. will take as much sperm as he can from the local sperm bank over the next couple of days, and force feed her.  That, along with the male staff, including himself, should do it.

 

The slut's eyes glaze over as she cums in her own mouth again, her legs thrashing in the air, and the Dr. releases his own load into her ass.... his balls shrink further down...

 

It may not even take a couple of days...
