Last appointment

Though you want to hang out with your little sister more, you still have to go to the clinic as today is the end of your transformation and last appointment.

"Hey, Sarah? Are you asleep?"

"No."

"I need to go to clinic, so can you stand off of me, please?"

As you were freed from your sister's hug you head to bathroom and after quick shower you dress up in your room. You had to change your whole wardrobe several times during this month, now you have some clothes, a bit too few to your liking, but you always can fix it later. Right now you chosed a nice top, that covers your big breasts but leaves your middle open, and simple skirt, you didn't found any pants that could fit your much bigger than average dick and balls, even your panties that must be your size felt tight.

"Ah, it's you!" - Dr. Sanchez's eyes lit up when she sees you. - "Please, come and have a seat."

"So, do you had any pains? Anomalies? No? That's good..." - The woman bombarded you with usual questions as you sat down. - "Oh, also we received results of your last samples. And there's some anomalies... Nothing that could harm you, don't worry. Anyway, your pussy is fully functional, so you can have a kids, also your sperm still virile, usually we girls can't impregnate each other, but you somehow can, so we need more samples. Well, you need to be careful if don't want kids early."

"Okay, now when we finished the questions part, it's time for examination, so please strip down."

You take off your cloth for physical examination, you suspect Dr. Sanchez is enjoying these checkups, her cock start stiffening under her skirt as she prod and feel your naked body. By this time you noticed that your new body had arousing effect on other girls, though it's getting in the way sometimes you still think it's kinda fun.

"Say, when you cummed last time?" - asked doctor while she weighted your balls, indeed they're quite big almost as big as cantaloupes.

"Um, around a hour ago..."

"Hmm, interesting... Well, let's gather some samples..." - she took out a container and handed you a condom. - "But let's make it more interesting!"

Dr. Sanchez took off her skirt and bend over her desk and you saw that she isn't wearing any panties, her wet pussy and hard cock on display. - "Come on, what are you waiting for?"

You quickly put condom on your large cock and step behind woman. She eagerly thrusted her butt into your crotch. You can't resist and slapped her plump ass, then you lined your member with her dripping cunt and thrusted inside. Dr. Sanchez moaned as first inches of your cock stretched her pussy and her moans only grew louder as you continue feeding your snake to her cunt. Soon almost 2/3 of your dick was inside and you feel that it's her limit, so you start moving your hips in and out, in and out.

"Oh! Ahh~ Mmh, h-harder..." - Dr. Sanchez making pretty whorish noises as you fuck her. Hearing her request you tightly grip her fertile hips and increase your pace. She begin moaning even louder, most likely her moans are heard in hallway, though that not stop you from fucking the doctor even harder as you were approaching orgasm.

"Ah~ Ah! C-cumming!" - the woman cried and suddenly you feel as her pussy gripped your cock as her own untouched dick start twitching and spraying jizz on floor. You were on the edge yourself, so couple moments you push your dick as deep as possible and start filling your condom.

"Oh~ F-fuck, that was incredible..." - quietly moaned Dr. Sanchez when you pulled out your softening cock along with condom filled with couple liters of your cum from her gaping pussy. - "Please, put the condom in that container..."

"I suppose that's all for today, right?" - you asked as you put filled condom in the box and closed it.

"Yeah, the course is over. Congratulation, Doug... I mean Diana." - said doctor still catching her breath lying on her desk. - "You're free now, but don't hesitate to visit me again!"

"I'll keep it in mind, thanks." - you put on your clothes and leave Dr. Sanchez's office. In hallway you saw several other patients, they blushed as you walked away, some even had boners, probably they heard your doc's moans. Anyway, from now on you're not Doug but beautiful girl named Diana. You're free, at least for weekends, so the next question what to do now...
