The permanent injection, and it seems Harriet wants some .

"I think the Injection is the best bet, I mean if we don't want a cock we just don't think about having one while rubbing our clits." You giggle as you look over to Tanya who seems to nod.

"Good choice, now I have to inject this into your clit, which won't hurt, but I need you to stay still, so if you will follow me to my lab upstairs I have some chairs you can sit in, we'll get you both tied down, we'll inject you and then keep you tied down as your first orgasms will be messy." Harriet says as she leads you back upstairs to her lab, where she was watching your game earlier. You can barley contain your excitement as you think about Tanya fucking you nice and hard with a cock, and planting her seed deep inside you, you're still nice and fertile from the **** earlier so you could end up impregnated, and then return the favor.

You are led up to a set of chairs which look like the chairs you'd get at a gynecologists, only with straps on the leg stirrups and arms. You sit yourself down and rest up you legs as Tanya does the same.

"I don't suppose you're certified to give checkups are you?" You joke as Harriet straps down your arms and legs.

"Well actually I can, it's just a little fizzy on the details of who's certificate it is, but I'm qualified, after all I'm into all things fertile, and well needless to say that involves a lot of time staring at pussies and cocks." Harriet jokes as she ties down Tanya.

"Well that sounds like a fun job, do you need any sexy nurses?" Tanya jokes as she's tied down, and Harriet prepares the first injection of the bright orange liquid, and parts Tanya's swollen red labia and peels back the hood on her engorged clit.

"Mmmmm maybe, it'd be handy have two sexy sperm donors on hand to deliver fresh batches. Hold still Tanya this wont hurt in the bad way." Harriet giggles as she slowly pokes the needle into Tanya's clit causing a cry from Tanya that goes from pain immediately to pleasure. Harriet waits for Tanya to settle and then begins to inject the orange liquid into her clit, you marvel as you watch the clit visibly expand as she slowly fills Tanya's clit with the liquid, it even begins to form the shape of a cock, and by the time it's all injected the needle is removed from what would now be the urethra. A few beads of clear liquid drip from the head of Tanya's new cock, you also see two small orbs drop from the base of her cock and form into a smooth ball sack that begin to swell in size.

"One down now onto your girlfriend." Harriet says as she moves over to you, you feel her warm hands probed at your lips causing you to get wet at her touch, and even more so as she peels back her clit, you were already horny watching Tanya grow a cock that is slowly hardening and becoming erect. You feel a sharp pain as the needle sinks into your clit, the pain passes and then your feel a fire of lust build inside your core, you picture a cock in your mind one like Tanya's with some big heavy balls packed full of strong potent cum. You look over and see that Tanya is fully erect, and sporting a huge tool with big heavy balls, and her cock is more or less dripping with precum now. You feel you pussy get wet from the display but being tied down there is very little you can do about it. You look down and see you own cock rapidly forming, and also becoming nice and erect, you can feel the blood being drawn into it, which makes you ever so slightly light headed. You feel a small amount of relief as Harriet removes her syringe from your cock and marvel as it drips a few heavy beads of precum.

"Well now the cocks are sorted, as well as some nice heavy balls lets get your first orgasm milked out with my blowjob simulator." Harriet says as she reaches between you legs and opens up a small storage draw and takes out a large device which is long and cylindrical with pumps and a pair of lips on the end. You also not is has a tube at the back.

"Hey Harriet whats with that tube on the back?" You ask as you watch her place the devices over your rock hard cock, it slips over your cock and you feel amazing as it sits on you shaft. She flicks a switch and the device begins to pump up and down, pulling the mouth up and then down you cock. It feels amazing, you have no clue how close it feels to the real thing, but it feels really good, as you slowly begin to pump precum into it.

"Oh it collects cum silly, like I said you're first orgasm will be messy, and It'll collect all the cum up." Harriet says as you moan and groan as the machine continues to stimulate your brand new cock, as Harriet puts an identical machine on Tanya's rock hard and bulging cock. You lie back and moan and watch as your precum is sucked up the tube and pumped down, you realize you have no idea where it goes.

"Harriet......oh.....mmmmmm....where doessssss....the...cummmmmmmm....go?" You say between heavy moans and groans as the machine picks up pace, and you feel a pressure begin to build deep inside you.

"Oh I have something special for where the cum goes, and unlike typical ****, mine will be served white hot" Harriet giggles evilly as she slowly walks over to you.
