Prostate play

"I see you and Lizzie were talking" She said as John sat down. "That's good. It's good to put yourself back out there. What were you guys talking about?"

"Oh just small talk stuff" John blushed.

"Well, obviously I can't divulge anything from her meetings with me, but I think you two would make a good match. She's very much your type."

"Oh" John tried, and failed, to hide his excitement upon learning this.

"But enough about that, hows the medicine been affecting you? Any side effects?"

"I feel pretty good." John tried to be as vague as possible.

"Have you been able to last longer?"

"Yea"

"How much."

"Two or three minutes." John was embarrassed.

"That's good. I know it doesn't sound like much, but your still on a low dose. These types of medicine require increasing doses over time rather than giving you a full dose to start with. It helps your body get used to the changes. How has it made you feel on an emotional level?"

"Good."

"Good? Good how?"

"I don't know. I didn't notice much difference at first. It's hard to explain. I've definitely been more emotional. Not like crying are sissy stuff like that. It just feels... right, I guess. I don't know, does that make sense?"

"Absolutely. A feeling of comfort with one's self is often the first sign of recovery from depression."

"Yea." John beamed. "Comfortable. That's a good word for it. Although I still feel kind of weird and different."

"Well like I said, your not up to the full dosage yet. I'm glad you've reacted so well to this medication. However, there is one side effect I have to manually test for." She snapped on a glove.

"What's that?" John asked worried.

"This medicine can enlarge your prostate." She lied. "It's important we find out as soon as possible if that's happened."

"No." John shook his head. "That's okay, I think I'll just stop taking the medicine just to be safe."

"John" She started.

"No, it's fine. I'll just take something else."

"John, they all have this possible side effect." She lied again. "Besides, you said you feel good on this medicine. And we both know you don't mind the feeling of a finger up there."

"I do to!" John protested. "I'm not gay!"

"John, I didn't mean to insinuate you were gay. Liking prostate stimulation does mean you're gay, it means you're a man."

John shot her a skeptical glance.

"It's just a scientific fact. The prostate contains a large amount of sensitive nerve endings. More than the tip of your penis. However, it is also prone to getting enlarged and becoming hazardous to one's health. I need to check it."

"Fine" John relented as he stood up and took down his pants and underwear.

"Thank you. This time I think it would be wise if you weren't standing for this, given what happened last time. On all fours please." She snapped and pointed at the ground.

John sank to his hands and knees and braced himself. He flinched slightly when he felt a dollop of cold lube drip onto his asshole, which in puckered in response. Her finger slowly started to rub it in as she traced all around his puckering hole. John felt his cock getting hard despite himself.

"UUUGGGH!!" John grunted as he felt her finger tip enter him. It was only an inch in but it felt amazing.
"Oh my. You're much tighter than last week. Another possible side effect. But I need you to relax." She stroked his ass cheeks with her other hand. "I can't go any further until you loosen up. So relax. That's it. Think peaceful thoughts. Just focus on the pleasure. That's it."

Dr. Valentine slowly sank her finger in knuckle deep. Then she started curling her finger up, immediately finding his prostate. After less than a minute of this stimulation John felt himself getting ready to fire off.

"Oh god!" John gasped as his cock twitch and shot a thick wad of cum onto the carpet below. John was in bliss, he was cumming without even touching his cock. He had no idea such a thing was even possible. It's not gay, he kept telling himself, the doctor said so. And it feels so fucking good. His cock continued to twitch with each shot of cum, leading to a steady dribble. Finally his orgasm was over and John's arms gave out and his face fell to the carpet in exhaustion. Doctor Valentine kept her finger still in his ass through out this, and remained inside of him after his collapse.

"I know this can be kind of intense, but I'm not finished with the examination yet." She teased. "So I need you to collect yourself and let me know when you're ready to move onto the next stage."

John simple panted as he felt his hole still puckering around her finger. He laid there for a few minutes before he finally felt recovered.

"Okay," He said. "I think I'm ready."

Dr. Valentine smirked as she knew there was no way he was ready for what was coming next. She brought her finger almost all the way out of John's ass and slammed it all the way back in, then again, and again, and again, all in less than a second.

"FUCK!" John screamed as he felt her finger jack hammering into his asshole. It burned slightly, but John didn't want it to stop. He brought his hands to his cock and started jerking at the same pace as Dr Valentine's probing finger. Using his own cum as lube, He stroke himself to another mind blowing orgasm, after which his knees gave out and he collapsed flat on the floor, causing the doctor's finger to pull out of his ass with a loud popping sound.

"Well everything seems to be in order," She said keeping up appearances. "Now our session can start."
