Luka pulled into a parking spot and turned the car off. They undid their seat belts. He sat still, his left hand on the door handle.

“You okay, honey?” Lexy, his wife, asked.

He took a deep breath in. “Yes, I think so.”

She reached over and put her hand on his thigh. “Everything is going to be okay. Just think of the end result - we will have the baby we’ve been waiting for for so long.”

“I hope so”, Luka replied in a small voice. “I just don’t know what Dr Wolfe is going to do.” The fertility specialist had asked him to wear an old pair of pants that he didn’t care about and a long coat. He’d also told him to not wear underwear. And to not have sex or masturbate for two days prior to the appointment. However, he’d not asked anything of Lexy.

“We won’t know until we see him. Come on, let’s go in. The sooner we start, the sooner we will be finished.”

They got out of the car and walked the short distance to the building’s entrance. Luka was a tall handsome man, 6’1” and of proper weight for his frame, though at the upper end of “normal”. He had shortish blonde hair, blue eyes and was clean shaven. He was 39 years old. Lexy was 30, 5’2” with a few extra pounds, brown eyes and dark brown hair that fell to her mid back. Some would call her ‘pretty’, but she felt she was more average looking.

The Kellers had been married for 8 years and trying to conceive for the past 3. Luka was the ‘man of the house’ most of the time. While she was not timid or weak, Lexy did let him take control, both inside and outside of the bedroom. She did not work outside the home, at his request. She was the stereotypical housewife, keeping a clean, tidy home, doing their laundry, ironing his clothes and cooking wholesome meals from scratch. They had what they considered a very satisfying sex life and were a bit kinky from time to time. The only upsetting thing was their inability to conceive. They both longed to start a family.

However, Luka needed his breaks from being in control and at times relinquished it to his wife - sometimes as frequently as one or two days a week, usually on the weekends. At these times, he sometimes liked to revert to a much younger age and have her take care of all his needs. He needed a lot of reassuring on these days, though he also needed it when he was submissive, but not reverting to a younger age. Lexy sensed that he was going into a submissive, insecure mode this late Friday afternoon. He tended to do this when he was anxious or worried. Either that or he was just nervous about the appointment. Perhaps it was a bit of both.

They entered the front door of the building and walked up a short flight of stairs to the main floor, going to the first door on the left. “Dr Frank Wolfe, M.D. Reproductive Endocrinologist” read the plaque on the door. Lexy turned the knob and walked in with Luka following behind her.

They registered with the receptionist and took their seats in the waiting room. It was 4:55pm. Their appointment was for 5:00. She wondered why it was booked for so late in the day. Most doctors finished at 5. Luka, a cardiologist, booked his last patient at 4:30 to allow for when he got behind schedule. Today, his last patient had been at 3:30 to give him time to finish up and go home to change clothes and get his wife before going to the fertility clinic. Dr Wolfe had said she didn’t have to come to this appointment, but that he would like her to. She chose to go as they did almost everything together. Besides, this was an issue affecting both of them. And she wanted to know why the doctor would like her to come along with her husband.

The receptionist walked by them with her coat and purse. She smiled at the couple, then opened the door and left the clinic. A few minutes later, a man and woman came through the room and left the same way the receptionist had. Lexy figured they were patients, perhaps the last scheduled ones before their appointment.

Soon enough, Dr Wolfe appeared from the door to the hallway. “Hello, Mr and Mrs Keller”, he greeted them warmly. “I’m sorry I’m a wee bit behind schedule. Come with me, please.” Was it Lexy’s imagination or did he put an emphasis on the word “come”?

Luka and Lexy got up and followed the doctor down the hall. At the end, he turned right and led them into his office. It was pretty much what you’d expect a physician’s office to look like. A large Mahogany desk was by the window with two comfortable looking chairs in front of it and framed degrees and awards on the wall. A leather couch was along one wall and bookshelves lined the opposite one. Above the couch was a large painting of a water scene with boats and sailboats. On the fourth wall was a water dispenser with paper cups.

“Sit down, please”, Dr Wolfe said as he gestured to the chairs in front of the desk. As they took their seats, he walked around the desk to his chair. Sitting down, he opened their chart, which he’d had in his hand. He read the latest entry and scanned what looked to be a page of lab results.

“As I’m sure you remember, the last time you were here, we discussed the procedure for trying to find out why you haven’t conceived and I gave you a physical, at which I found nothing amiss, Mrs Keller. Your reproductive system seems to be in order, but as I said then, there could be something that wouldn’t show up on a basic gynecological examination. However, we won’t go into further testing just yet.

“I had both of you get blood drawn for lab work and the results are normal for each of you. So what I am going to do today is get a couple of semen samples from you, Mr. Keller. I will have them tested and then we will go from there, depending on what the results are. Do you have any questions?”

“No, I don’t think so”, Lexy said.

“None here”, Luka replied. “But please call us Luka and Lexy.”

“Okay, Luka and Lexy, follow me. Do you wish to be present for the semen collection, Lexy?”

“Yes, if I’m allowed.”

“You are. As long as Luka is okay with it.”

“Yes, definitely.” Luka said to him. “In fact, I want my wife to be there for it.” That didn’t surprise, Lexy. She knew her husband was nervous and she had a calming effect on him.

Dr Wolfe got up and they followed him across the hall to an examination room. It was pretty large for an exam room, about double the size of the average one. An exam table was on one wall, a desk on the opposite one with two chairs beside it. On the third wall was a counter with a sink and cupboards and drawers under and above it. A coat rack stood in the corner behind the door.

There was the usual array of instruments on the wall beside the exam table and a wall mounted light near the foot was on an arm to allow the examiner to adjust it’s position.

The Kellers sat down in the chairs and Dr Wolfe closed the door. “Just habit”, he said. “Nobody else is here, everyone has gone home.”

A puzzled Luka looked at his wife. Something weird was going on. Why was their appointment for after hours?

The doctor sat down and set their chart on the desk. He turned his chair toward them and leaned forward to address them. “I am going to use some unconventional techniques on you”, he said to Luka. “This may seem strange and it will be uncomfortable at times - though you may also enjoy it - but keep your eye on the prize. Do you consent to this?”

Luka looked at Lexy for direction. She nodded her head ever so slightly. “I consent”, he replied with a shaky voice. He was getting more nervous, but he trusted his wife. He had long ago accepted his tendency to be nervous and insecure when in strange situations or when he was feeling anxious about something. It was embarrassing for others to see him like this, but he was thankful that his wife was so understanding and willing to take charge.

“Good. Now, please come over to the table.”

Luka gulped out of fear but rose from his seat. “I’m going to do a quick basic exam first. We were running behind last time and I didn’t have time to do one. That is part of the reason I booked you in the last slot today - so we would have plenty of time. I don’t have my kids this weekend, so I’m in no rush to get home. You seem very nervous, Luka.”

“I am, Dr Wolfe.”

“There’s nothing to be afraid of”, he said as he put a hand on the small of Luka’s back and guided him to the table. “I’m not going to do anything to you that you don’t want me to do.”

The doctor was about Luka’s height, maybe a fraction of an inch taller. He was in his mid 50’s with short grey hair, green eyes and a bit of a ‘beer belly’. The cardiologist in Luka wanted to tell him about weight and heart disease, but he held his tongue. He wasn’t the doctor’s doctor. Dr Wolfe had laugh lines around his eyes, but other than those and the grey hair, he showed no signs of his age.

“Hop up onto the table”, he instructed. Luka complied. Dr Wolfe looked into his eyes, ears and throat with the instruments on the wall, then pulled his shirt up out of his pants. He took his stethoscope from around his neck and slipped the diaphragm under Luka’s shirt to listen to his lungs, having him breathe deeply each time he moved it. When he was finished, he undid the top few buttons of his patient’s shirt to listen to his heart. He was very thorough with the auscultation, listening at all points, but paying particular attention to the mitral.

“Your heart sounds good, Luka. Please lay down on the table.”

The patient swung his legs up and over the table, at the same time reclining back. The doctor undid the rest of his shirt and pushed it open, exposing his chest and abdomen. To Lexy, the doctor’s gaze on her husband’s chest seemed to linger longer than it should have for him to do a visual assessment. She couldn’t blame him, though. Luka didn’t have six pack abs, but he still had a nice chest with straight dark blonde hair over most of it.

Dr Wolfe first auscultated Luka at all 4 quadrants, then the aorta just above the belly button. Next, he percussed and palpated Luka’s abdomen. Finally, he told his patient to sit up and get off the table. The doctor sat on his stool at the foot of the table and asked his patient to come and stand in front of him. Lexy moved her chair a bit so she could see better. Luka blushed, but he didn’t protest. She was his wife and was allowed to watch if she wanted to.

The physician reached out and undid his belt and pants, but did not pull them down. Luka was not wearing underwear, as per the instructions Dr Wolfe had emailed to him a week prior. Lexy watched as he reached in and palpated her husband’s groin, which he had shaved this morning, once again according to instructions he was given. The doctor asked him to turn his head and cough a couple times, checking to see if he had a hernia. She thought he was taking longer than necessary, but she’d never watched this before, so she couldn’t say for sure.

Once he was done the hernia check, he palpated Luka’s shaved testicles. At this point, the beginnings of an erection began to appear in his circumcised penis. This embarrassed Luka and his face turned red. Dr Wolfe looked up at him. “It’s a normal reaction”, he reassured his patient. “You are not the first man to have this happen and you won’t be the last.” Luka looked to his wife for reassurance.

“It’s okay, honey”, she told him. “Listen to Dr Wolfe. It’s nothing to be embarrassed about or ashamed of.” He sighed in relief.

“All right, Luka, I’m finished with this part of the exam”, the physician said as he did up the button on his patient’s pants, making sure his penis and testicles were on the outside of the garment. He collapsed the leg extension on the examination table. “Bend over and put your hands flat on the table.” Luka did as he was told.

Dr Wolfe pulled out a drawer and rifled through it. He took out what looked to Lexy to be a stitch ripper, a tool used in sewing to take stitches out of a garment without tearing the garment. She wondered what he was going to do with it. She got her answer right away.

He approached her husband. “Luka, I’m going to put my left hand down the back of your pants. Don’t be startled.” He knew his patient was nervous and wanted to make him more at ease. The doctor did as he said he was going to do. There wasn’t much slack in the trousers as Luka had a nice, rounded butt. Dr Wolfe didn’t want to stick him with the stitch ripper. He placed his hand over the inside of the seam to protect his patient.

With his right hand, he poked the stitch ripper into the seam at the bottom and pulled upwards, ripping it (the seam) apart. He set the tool on the counter and put a glove on his dominant hand. Next he picked up a tube of medical lubricant and squeezed a bit onto his index finger. “I’m going to do the rectal exam now. I want you to relax.” With his left hand, Dr Wolfe parted the ripped out seam and put his right index finger on Luka’s anus and gently pushed on it. He could feel the man tense up. “Relax, Luka. Have you ever had a rectal before?”

“No”, Luka replied, almost in a whisper.

“You are getting close to the age where you should have one on an annual basis. You need to get used to this.”

“I’m sorry, Doctor, I can’t help it.”

“It’s okay, we aren’t on a time limit tonight. Keep trying to relax. Try this - take a deep breath in and hold it. At the same time, bear down on my finger, like you do when you are having a bowel movement.” Luka did as directed and the doctor’s finger slid into him. “You can breathe out now, Luka. My finger is in.” A moment later, he pulled it out. “Everything looks fine. Now, I’m going to do the semen collection.”

Dr Wolfe took his glove off and disposed of it. He opened a drawer and took out a sample container, which he set on the exam table. Reaching into his lab coat pocket, he took out a condom and a ring and set them on the counter. He undid his zipper and pulled his erect cock out. Lexy could see that he was a little longer than Luka and, while a decent circumference, not nearly as big around as her husband. She watched as the doctor put the condom on and then slid the ring down the shaft to the base.

Luka turned around and saw what he was doing. His eyes got wide. Lexy noticed his look and asked him “Are you still okay with this, honey? You can back out at any time.”

“Yes.”

“Are you sure?” The doctor asked him. “I imagine you have figured out what is coming next.”

“Yes, I’m sure.” He was now fully erect, which told Lexy she had been right when she thought her husband would enjoy this.

Dr Wolfe put a hand on Luka’s shoulder. “Let’s get back into position, shall we? Don’t worry, I’ll go nice and slow, but like your wife said, you can back out at any time. Say the phrase ‘red light’ and I will stop right away. If you want, you can say ‘green light‘ to indicate you are okay and like what is happening. But you don’t have to, I can tell by your body language.” Luka nodded and bent over the table once again.

The doctor picked up the specimen cup and unscrewed the lid before setting it back down on the table. “Lexy, when he’s about to ejaculate, hold this over the tip of his penis to collect the semen. Don’t let it touch the sides.”

“Okay, Dr Wolfe.” She could see the pre-cum on the tip of his penis and knew it would not take him long. Especially if he liked what the doctor was doing as much as she thought he would.

The specialist went back around to behind Luka. He put on another glove and squeezed a large glob of lubricant onto his finger. As he had done before, he rubbed it over the patient’s anus before getting another glob and pushing his finger through to lubricate the inside. When he felt his patient was sufficiently lubricated, he removed his finger and took the glove off. After disposing of it, he stood behind Luka.

“Luka, you’re going to feel pressure on your anus”, he said in a reassuring voice. “Do as you did with my finger and take a deep breath in while bearing down.” Luka nodded. Dr Wolfe place the tip of his penis on Luka’s anus and pressed on it very lightly. Luka evidently had never had anal sex before so he needed to be patient and gentle with him.

Luka gasped as he felt more pressure. “Are you okay, honey?”, Lexy asked.

“Yes, sweetheart”, he replied. She approached him and brushed some hair off his forehead with her hand before putting her hand over his. She wrapped her fingers under his and squeezed to reassure him. “Ahhhhhh!” he gasped as the doctor pushed farther into him.

“Are you okay?” Dr Wolfe asked as he stopped pushing his cock into Luka. He took his hands off Luka’s hips and leaned forward, wrapping his arms around his anxious patient in a hug.

“Yes, Doctor”, was the reply. “It hurts, though.”

“It will only hurt for a very few minutes, sweetie. But you have your safe words, use them if you want me to stop.”

“No, I don’t want you to stop. I’m okay. Green light.” He looked at Lexy, who smiled at him.

The doctor resumed pushing into Luka’s anus. “Remember, bear down on me”, he said “and take a deep breath and hold it.” Luka complied and Dr Wolfe pushed the head of his cock all the way through his anus. The shaft was much easier to get in. “I’m in, Luka, you can breathe now and stop bearing down.” He stood still for a moment, letting Luka get used to the sensation of a penis being inside him. Then he slowly pulled back until just the tip was inside. He pushed his shaft back in and continued to do this, very slowly at first.

Luka could feel his doctor’s cock rub over his prostate each time he thrust in and pulled out. It was a feeling like none other he’d ever experienced, not even when Lexy sucked him until he came in her mouth. He moaned with pleasure.

“Are you still okay?” Lexy asked. “Yes!” he exclaimed. He could feel his orgasm building up and knew he was going to climax very soon. He didn’t want to. He wanted Dr Wolfe to keep fucking him, but he feared he’d stop once the semen sample had been collected.

The doctor’s thrusts were getting faster and faster. He reached around Luka and took his cock in his hand and pumped it a few times. Luka’s breathing was getting faster and the muscles in his anus were clenching his doctor’s cock. Lexy was watching her husband’s face. She saw the look he got just before he came. His face was flushed and his lower lip quivering. She put the specimen cup over the tip of his penis just in time. Luka shot spurt after spurt of semen into it as he cried out in pleasure. He didn’t even try to muffle it. He was a heavy cummer and took a few seconds more than most men would. She kept the container steady so that her husband’s member would not touch it, as their doctor had instructed.

When Luka was spent, Dr Wolfe withdrew his cock from his anus. Luka was disappointed. He had hoped the doctor would cum in his ass, even though he had a condom on. At least he would have been able to feel him twitch inside him - or so he had hoped.

Lexy put the lid on the specimen bottle and handed it to the doctor who set it on the counter.

“How did you like that, Luka?”, he asked. Luka turned around to face his doctor.

“It was great!” was his reply. “I loved it! Once it stopped hurting, it was so hot!”

“Would you like some more?”

“Oh, yes, Dr Wolfe, I sure would!”

“Okay, we can take a second specimen. Just in case the first one gets dropped or otherwise damaged.” He winked at his patient. Are you okay with that, Lexy?”

“I have no problem with it.”

“I think we’ll do this collection a little different, Luka. He reached out and undid the button on his pants. “Take your pants off and get up on the table and lay down.”

Luka did as told and handed his pants to Lexy before getting on the table. She hung them up on the coat rack. He layed down on the table. “Where do I put my legs?” he asked.

The doctor opened a cupboard under the counter and took out a pair of stirrups. As he put them into their slots on the table, he answered “In these, Luka.” Luka was laying with his knees bent and his feet flat on the table. The physician took one foot and guided it into the stirrup, then did the same with the other foot. His patient’s legs were wide apart. I’ll bet most gynecologists wish their patients would keep their knees as far apart as Luka is keeping his, he thought to himself.

He stepped up to the table and realized it was a bit too low, so, using the foot controls, he raised it up a bit, so that Luka’s anus would be at cock level. He stepped closer. Luka was already erect again. He is going to make a very good fuck buddy, he thought. That is, if he and his wife agree to see me again.

He opened a condom that he’d taken from a drawer when Luka had agreed to another collection. “This time, I’m going to collect your semen with this”, he said to his patient.

“Why?”, Luka asked.

“Just for something different, that’s all.” He put the condom on Luka’s penis and gave it a couple strokes before putting his cock at Luka’s anus. He gently pushed on it as he watched his patient’s face. He could tell it was hurting again. He knew that it almost always does hurt for a couple minutes or so, no matter how experienced the man is.

Lexy saw it on her husband’s face, too. She took his right hand and held it in both of hers. “Are you all right, honey?” she asked.

He nodded and said “Oh, yes! “

Dr Wolfe kept steady pressure on his anus and was in in a moment. Once again, he stood there for a minute and leaned over and stroked Luka’s hair, looking into his eyes. Luka smiled up at him. The doctor looked at Lexy and asked “May I?”

Lexy, knowing what he meant, replied with “Yes, as long as Luka is okay with it.”

“Luka, may I kiss you?”

The question surprised Luka. He’d never considered himself bi sexual but the thought of being kissed by Dr Wolfe while he was being penetrated by him turned him on. He could feel his cock get harder, if that was possible. “Yes”, he replied.

The doctor put his lips on Luka’s and kissed him a few times as he started to thrust in and out of him. He took one hand off the table and ran it over his chest, feeling the soft hair under his palm. As he straightened up, he ran his hand down Luka’s abdomen to his groin. He wrapped his fingers around his cock, which was quite big around. Certainly bigger than his own penis. He pumped up and down a few times and could tell Luka was close to cumming a second time.

He pulled out and removed the ring and condom. Luka watched him. “Is that all?” he asked.

“Oh, no, sweetie. I’m just ditching these before I enter you again. Are you okay with bare back?”

“Yes, Doctor Wolfe. I’m very okay with anything you want to do.”

The doctor approached the table again and entered Luka. This time, he went in faster. Luka called out in a mix of pleasure and pain. When he was all the way in, he thrust in and out, slowly at first, then picking up speed just a bit. After a few minutes, he took his patient’s feet out of the stirrups and pushed his knees up. Then he held the underside of his thighs as his thrusts got faster. Luka was once again moaning with pleasure.

Frank Wolfe watched his patient’s face and soon saw the signs of impending climax that he’d seen the first time. He sped up his thrusts. Both of them were breathing hard, their chests rising and falling almost in unison.

“Cum inside me!” Luka said.

“Tell me you want my cum inside you, Luka.”

“I want your cum inside me, Doctor!”

The doctor grunted as he came, injecting his hot cum into his patient.

Luka, feeling Dr Wolfe’s semen inside him, cried out again as he exploded into the collection condom. It felt like there was more cum coming out of him. When he was finished, the doctor leaned over again and kissed him once more. “You did great, Luka!”

“Thank you, Dr Wolfe. It was so good!”

“You stay just like that for a minute.” He had set Luka’s feet down flat on the table.

The doctor took the condom off and set it in a fresh specimen jar, noticing the amount. He then pushed his own cock into his pants and did them up. Next, he got an adult diaper from the cupboard. “I’m going to put this on you, Luka. It’s for leakage, so you don’t get it on your pants. Can you raise your bum for me?” He slid the diaper under him, then brought the bottom up over Luka’s penis. Next, he brought the sides together, securing them with the tape.

Luka hadn’t worn a diaper since he was a toddler. He blushed with embarrassment and turned his head toward the wall. “There’s no need to be embarrassed, honey”, Lexy said to him as she stroked his hair. “It’s just the three of us, nobody else knows. I won’t tell anyone and I’m sure Dr Wolfe won’t either.”

“She’s right, Luka. I won’t be saying a word to anyone. Obviously, it won’t go on your chart either. Nor will the way the specimens were collected.”

“Okay, Doctor”, he said in a quiet voice. He sat up and got off the table. Lexy handed him his pants and he put them on, then he did up his shirt and tucked it in. He put on his coat. “I see why you asked me to wear a coat”, he said.

Dr Wolfe laughed. “I’ll give you a call when I have the results of the sperm analysis. It should only be a few days.”

They said goodbye and Luka and Lexy walked to the car. Luka was over his nervousness but he was still acting insecure and submissive. “I’ll drive”, she said without asking if he wanted her to. She opened the passenger door and he got in. She pulled the seatbelt over him and did it up before kissing him and closing the door. Then she walked around the car, got in on the driver’s side and did up her own seat belt before turning the key in the ignition and starting the car. She was happy that her husband had enjoyed what took place in the clinic. She was pretty sure he would as he’d expressed a curiosity about having a man fuck him on more than one occasion. How fortuitous that she ‘met’ Dr Wolfe in an internet chat room and that her and Luka needed a fertility specialist - AND that he agreed to see them and collect Luka’s semen in a way he’d never done before, though he was no stranger to having sex with other men.

As they drove out of the parking lot, Luka said “I wish Dr Wolfe wasn’t our fertility specialist.”

“Why, honey?”

In a small voice, he replied “I want to see him again and again and again.”
