Amber read the sentence and thought of a change that she just had to try. She deleted the word hand and replaced it with cock. Amber didn't know what would happen but the app seemed magical so she pressed enter on her phone and looked back at the examination. At first Amber didn't see anything different from before and was starting to feel silly for believing the her app was magic, when Dr. Long stood up abruptly and put her hands on her crotch.
"Now Diane we have two ways of testing your fertility the normal way or this way" said Dr. Long now standing almost crotch to crotch with the lady strapped to the examination chair.
With the loud sound of meat falling onto meat Dr. Long had finally undone her pants and a large cock slapped down onto the exposed woman.
"As a Futanari I have the innate ability to know the fertility of those I have intercourse with" stated Dr. Long I an oddly professional tone even though her eyes gleamed with lust.
"So which option will you choose" asked the doctor as her fat slab of flaccid cock rested on her patient.
Both Amber and Diane were beat red after the display that the doctor had just given. Amber was starting to gain memories from this new reality and while the her of this reality had known Dr. Long had a cock this was the first time she had seen it.
"Amber our patient appears to be in shock could you give her a little encouragement" asked Dr. Long now looking at her assistant.
Amber wasn't sure what the doctor wanted but she rushed over to the patient and decided that she would do what she could to persuade Diane to take that cock.
"Now Diane you can still take the normal test. It will be a little painful and you won't get the results for a while or you can take Dr. Long's test. It will be extremely pleasureful and we will be able to imidiatly tell your jerk husband that you are the fertile one and he is the problem" said Amber.
"I ...I ..I ... doctor's test" stuttered the patient in a barely audible voice
"What was that" asked the doctor lifting her hardening cock off the the patient's stomach.
"I would like to take the doctor's test" said the patient a little more confidently
"Louder" said Dr. Long dropping her cock back onto Diane causing a loud slap.
"I want your huge cock to tell me I'm a fertile b**ch" shouted Diane starting to wriggle and rub against the cock on top of her.
"Good girl. You'll get exactly that" answered Dr. Long stepping back a little to better position for her entry of the now sopping wet pussy infront of her.
Dr. Long's cock was now fully erect at almost 11 inches long and almost as thick as a soda can. Amber looked on in amazement as the doctor rubbed the precum that had started to flow all over her cock and press its head at the entrance of the patient. With a sickening squelch and a loud moan from Diane the head of the doctor's turgid mushroom got shoved into the tight hole it was trying to explore. Slowly Dr long pressed in and Amber watched as the cock began to disappear into the patient. Diane was panting and moaning and occasionally crying out how good it felt or how the doctor shouldn't stop.
At about 8 inches deep the doctor ran into the patient's cervix and couldn't go in any further. The doctor then pulled her cock almost completely out of the patient and then in a violent motion shoved herself back in slamming into the entrance of the patient's most private depths. This caused Diane to moan louder and become more graphic in her remarks. The doctor continued to pull back and then slam into the patient fucking her in a spectacular fashion. Amber was at first hypnotized at the erotic sight before her but then snapped out of it and went to the patient and begun to massage her large breasts eliciting further moans from her.
This went on for a while until the doctor pulled back and stopped for a moment.
"I think your ready for the end of this test my little slut" said Dr. Long with a grin on her face. After saying this the doctor pushed in harder than she had before and with an audible pop the womb of the patient had been entered and all 11 inches were submerged. Diane leaned back and started screaming in rapture as she began to spray girlcum all over the doctor's crotch.
"I knew it. You are perfectly fertile if not overly fertile. It must be that self centered husband of yours that is infertile" exclaimed Dr. Long as she bottomed out in the young woman.
It was a few minutes later that the patient was dressed and thanking the doctor for letting her know that she was healthy. Dr. Long was back to her kind and professional demeanor and said that she was glad she was able to help and that if Diane needed to see a doctor again she should come here. Dr. Long then turned to Amber who had kept silent for most of the experience. The doctor thanked her assistant for the help she provided and that she was sorry if she put her in an uncomfortable situation. Amber said that this had been one of the most exciting things she had ever witnessed and that she hoped to help the doctor on other occasions. With that Amber returned to the front desk and sent the next patient in to see the doctor.
Amber then pulled out her phone and wondered at all the crazy things she could do with the app.
What does Amber do next
