Doctor Ama Rio sits with patient Katy Faery, discussing the experimental breast augmentation therapy, and explains how it's new and there's a few possible side effects. Katy tells Doctor Ama she understands, and really doesn't want surgery, so she will try anything to make her boobs bigger. Doctor Ama gives her a quick exam, checking her breasts to make sure she's a good candidate for the procedure. Ama lifts Katy's shirt, and shows off her breasts as she gets her all hooked up with electrodes and measures her. Ama hands Katy the liquid, and Katy consumes it from the vial, and starts to feel her breasts tingling. Katy's breasts grow bigger and bigger, and Doctor Ama starts to get turned on as she watches them grow. Doctor Ama wants big tits like Katy too, so she consumes the liquid and her breasts start to grow too! Katy is excited they will be tit-twins, and watches as Ama's tits grow huge. Ama and Katy rub their big breasts together, and cum over and over as they rub their boobs together. They motorboat their own tits and cum hard together, then compose themselves and sit back down and finish up the paperwork. (Interested in commissioning a custom clip with Ama or Katy?
