You end up pointing to Sera, "So it's you and me sweetie? Awesome, let's get this test run started!" Sera excitedly cheered as she hopped up from her seat. Her thigh length purple hair, which she had left down today instead of her usual more contained hair style flowed behind her as she made her way to you. Her outfit once again was just her black underwear, a black mini-skirt, and a black leather and lace, corset bustier top which held her 2 watermelon sized breasts. You couldn't help but start at their jiggly surface as each and every step cause them to move hypnotically. She by far was the biggest in terms of cup size of all of you. Coupled with the fact that she almost always wore corsets and heels, meant that your memories were filled with you just ogling her boobs. Of course, you would return the service on occasion too, so it apparently was kind of a long running thing between the both of you.
"So, what do I need to do, sexy?" Sera said as she gave your ass a squeeze. You didn't mind it at all and just let her continue groping you while you explained. "Mhmmm, ok so you put this on like a strapon ok?" Sera nodded and grabbed the device, slipping off her mini-skirt and panties in the process. Then she put it on and looked back at you for your next instructions.
"Ok, now in order to get me pregnant, this device will make the inside of your wombs compatible with your partner's genetics like I mentioned earlier." You explain while also remove your lower clothing. However you noticed that the business end was a bit dry. And you hadn't thought to bring any lub with you either. "So much for being the world's smartest. I am still a total clutz when it comes to presenting it seems." You thought to yourself. "Ah well, nothing a little bit of spit wont fix." You kneel down and place the rod into your mouth in order to wet it down, however you accidentally turn it on, and the straps tighten around your head, locking you in. You begin to panic, but can't do anything about it as you had designed it to be uninterruptable for saftey concerns.
Sera on the other hand is now experiencing a tremendously large abount of pleasure, as you designed the process to be quick. However, the key part to the whole device was on your end. You had programmed it to scan and find the idea birthing location and then modify the interior of it to become an ideal environment for your pregnancy. Under normal circumstances, this should, basically 100% of the time, use your womb. But now that wasn't an option. So the device scanned the relative area for the proper place which didn't exist. You never thought to put in place a failsafe for this. Meaning that if it couldn't find one, it would make one.
Suddenly you feel numerous tubes slide down your throat and begin to form a new cavity for your new womb. And, much to your shock and horror, it is making not one, but 2 of them. One in each of your breasts. You can feel the breast tissue get moved aboit as 2 pockets of space are formed and the surrounding walls are altered into a womb. Finally another exit is formed through each nipple, and as rhe tubing slips back into your throat, it deposits the genetic code aquired feom Sera into each of youd titty wombs, and seals up the holes they have made. Then they finish returning back to your throat and into the rod, where the process finally completes.
An automated message is anounced to the room. "Congratulations. Jamie. You. Are. Pregnant. With. Twin. Girls." Sera finally opens her eyes, seeing your current position. The rest of the room is staring at you in shock. While the process was painless, it must have caused your body to look very weird as the tubes reconstructed your boobs into wombs. Finally the device lets go of your head and you pull yourself off of it. "Fuck, that wasn't meant to happen." Sera looked at you confused "Wait what happened?" She hadn't been able to pay attention durring the process due to the pleasure.
"Well, because of an oversight onnmy part, my tits now each contain a womb with one of the twins inside them. And I will be birthing them through my nipples it seems." The rest of the girls gasp. "Now now, no need to worry. I am going to be fine, and hey, I am still pregnant am I not?" Now then, does anyone else want a go at it? Just don't put your mouth on it and accidentally start it" you joke. You were upset at the nature of your pregnancy, but were so happy that it actually worked that you just couldn't bring yourself to stay mad.
The twins immediately volunteered and to your surprise, both of them repeated what you just had done. Now they were both pregnant with twins, who would be born from their new breast wombs too. "Hey, why did you do it that way!" You exclaim. Both girls smile at you and say at the same time. "Because its by far the kinkier option, and now we match you as well."
