Luka stopped regressing Sunday evening. Lexy was relieved. She wasn't sure what she'd do if he was still in child mode come Monday morning. So far, he'd always come out of it before having to go to work, which she was thankful for.

When he was back to adulthood, they talked about what had happened on Friday. Luka was very happy with what had happened – all of it. Lexy was relieved about that, too. She had been a little apprehensive, wondering how he would react to it all.

“I loved it all, Lexy – the diapers, the anal fucking from Dr Frank – oh, how I loved that! I was hoping he would do it again when he came over Friday night, but I guess an old guy like him can only get hard once in a while.”

“Don't let him hear you say that!” They both laughed.

“How do *you* feel about it?” he asked her.

“I loved it, honey! It made me very horny!”

“Why didn't you say something?”

“You were in little boy mode. It didn't seem right.”

“But it was okay for the doctor to fuck me?”

“You have a point, Luka.”

“How about the diapers? Were you okay with that?”

“Yes, honey. You know I would do anything for you. Even that.”

“I know, but I'd like you to enjoy it.”

“I'm getting used to the idea, I think I do enjoy it.”

“You think?”

“Give me time, Luka. The diapers are so new.”

“What about the rest?”

“I love you and it makes you happy. I like making you happy. You know, I think Frank likes you a lot.”

“I hope so. I like him a lot. But does he like me as an adult or only as a little boy?”

“Oh, I think he likes you as an adult, just in a different way.”

“I'd like to have sex with him as an adult. Would you be okay with that? You could watch – maybe join in if you wanted.”

“I would love to watch - or join in.”

“Dr Frank is bi sexual, so I'm sure he'd be okay with it.”

“Would *you* be okay with me and another man?”

“Yes. It would only be fair.”

They were in bed and Luka leaned over and kissed her. They forgot about everything else for a bit.

Monday, when Luka was at work, Lexy went shopping online, where she ordered baby stuff in adult sizes - some sleepers, onesies, clothing for little and baby boys, a couple pacifiers, a few washable change pads, a couple sippy cups for when he regressed to toddler stage, a big bag to carry what she would need to take if they went out and a few other things. While she did not work outside the home, Luka was very generous with his money and she had her own credit card. She paid for expedited shipping so that she would have the items in a couple days.

Thursday afternoon, Frank Wolfe called Lexy while Luka was at work. “Lexy, I have the results of Luka's sperm tests and I'd like to come by tomorrow night to discuss them.”

“You don't want us to come to the clinic to get them?”

“I think it would be best if I come to your home.”

“Oh. Of course it's all right. It just seems so ... abnormal.”

“It is, but I have a reason. Can you not say anything about what I am about to tell you to Luka until tomorrow night?”

“Okay.”

“The results aren't good. That's all I will say for now, I'll tell you exactly what they are when I'm there. I'm afraid it might send Luka into a regression and I think it would be better for that to happen at home.”

“Oh, no, Frank! Of course, I understand and yes, it is fine to do this here.”

“Lexy, if his reaction is really bad, would you be okay with me staying the night? It might help calm him down.”

“Yes, Frank. Of course. Do you expect it to be bad?”

“I wouldn't be surprised. Men have a hard time dealing with being infertile. Right or wrong, it makes us feel less of a man. With Luka's tendency to regress in times of stress, I wouldn't be surprised if this is harder on him than the average man. ”

Lexy didn't say anything to Luka about Frank coming over until Friday at supper. They had talked about the tests Wednesday night, wondering when they were going to hear about them, but she thought it best she not say anything until as close as possible to when the doctor was going to be there. She was worried enough for both of them, she didn't need Luka worrying as well.

“Honey”, she said to him over his favourite meal of roast beef with roasted potatoes, carrots and onions, “Frank Wolfe is coming over at 8 to discuss the results of your tests.”

“He's coming here? That is odd.”

“I know! He has become a friend, though, so maybe it's not so odd.”

“Or there's something wrong and he doesn't want to tell us in clinic.”

“Let's just wait and see what he says, okay?”

Luka helped Lexy with supper clean-up as he always did when he wasn't regressing. Then he went to the living room and turned the TV on while Lexy put on a pot of coffee. She went to the bathroom and freshened up a bit, then out to the living room. She looked at the TV. It was on a children's channel. Oh no! she thought. He can't regress right now! “Luka, how old are you?” she asked.

Luka held up 4 fingers, indicating 4 years old. “Honey, you can't regress now”, she said as she sat down beside him.

“Why not?” he asked.

“Because you need to be an adult to hear and process what Dr Frank has to tell us. Please, honey. You can regress after he leaves, but come on back to adulthood for now, okay?”

“Okay, Lexy.” He picked the remote off the coffee table and turned to an adult oriented channel.

“Thank you, honey. Let's deal with whatever it is as best we can.”

There was a knock on the door. Lexy answered it and Frank Wolfe stood at the door, holding their chart. “Come in, Frank”, she said.

“How is Luka doing?” he asked.

“He's nervous, but okay. He regressed for a few minutes, but I talked him back. He doesn't know that you told me anything, he thinks that because you are coming here, it's bad news.”

“Be prepared for him to regress again.”

Lexy served coffee and again sat down beside Luka. She put her hand on his thigh.

“Luka and Lexy”, Frank began. “It's never easy giving this kind of news, but I've found the best way is to be direct. The tests on your semen samples are in, Luka. They show that you have a very low sperm count. The likelihood of Lexy conceiving naturally is extremely low.”

Luka looked like he'd just been punched hard in the gut. “Is there anything that we can do?” Lexy asked.

“Normally, with low sperm count, we would either put the man on medication to increase it, or get multiple ejaculations and combine the sperm from them and artificially inseminate the woman with it. In this case, I don't think either option would work. My advice would be to either go with a sperm donor or adopt.”

Luka got off the sofa and headed down the hall. Lexy got up and followed him to their bedroom. He pulled a suitcase from his closet and put it on the bed. “What are you doing?” Lexy asked as he opened a drawer in his dresser and took some clothes out.

“You don't need someone who isn't man enough to give you a baby.”

“Luka, stop that! I love you. It doesn't matter.”

“You want a baby. I can't give you one.”

“I can live without a baby, honey. I can't - and don't want to - live without you. Please stop this.” He looked at her with tears in his eyes. She had a few in hers, too. He sat down on the bed dejectedly. Lexy sat beside him and rubbed his back. “I know it's a hard blow, Luka. I'd feel the same if Frank did tests on me and I was unable to conceive. But we'll get through it - together.”

Luka leaned his head on Lexy's chest and she brushed some hair out of his face with her free hand. “Lexy, I don't think I can get through the night without regressing.”

“It's okay, Luka. If you have to regress, do it. I needed you to stay an adult until Frank told us the results. I'm not surprised that you need to regress.”

Frank peeked his head in the door. “Everything okay?” he asked.

“It's better”, Lexy replied. “Come on in.”

The physician stepped into the bedroom and saw the open suitcase and clothes in it. “Who's leaving?”

“Neither of us, Frank. Luka was going to but I talked him out of it.”

“Oh, good.”

“I think he's going to regress, though.”

“That's not unexpected. Luka, would you like me to stay here tonight?”

Luka lifted his head and looked at Frank with wide eyes. “Would you, Dr Frank?”

“Yes, Luka. I will if you want me to.”

“I want you to.”

“Then it's settled.”

“How old are you, Luka?” Lexy asked. He held up two fingers. “He was four when he tried regressing earlier”, she told Frank.

“I think maybe we should get a diaper on you, Sport”, Frank said to Luka. “We don't want you having an accident. Let's go to your play room and I'll put one on you.”

Luka followed Frank to the play room. Lexy said she was going to get something from the spare bedroom. She went into the packages that had arrived with her internet purchases and got out a change pad, sleeper, soother and bottle, then headed for the play room. Frank had got Luka's pants off and was removing his shorts. “Here, Frank, here's a change pad”, she held it out to him.

He took it from her and opened it up, then slipped it under Luka. “Someone has been shopping.”

“I sure have. Here's a sleeper for him and a soother. I'll go warm some milk up for him.”

“I'll be out as soon as he's changed.”

Frank diapered Luka and put him into the sleeper, then took him to the living room. He turned the TV to a children's channel for him, then he joined Lexy in the kitchen. “That went better than I expected.”

“I don't know what I was expecting, but it sure wasn't for him to try to leave me.”

“At least you talked him out of it.”

“For now. I hope for good. Yes, this is devastating but I married him 'for better or for worse'. That includes fertility issues. If he can't give me a baby, he can't. It doesn't diminish my love for him one bit.” She poured the warmed up milk into the bottle and screwed the cap on before heading to the living room. She sat down on the sofa and laid a nursing pillow over her lap. “Time for your bottle, Luka, honey. Come and lay across my lap.”

Luka had been watching her and now he had a big smile on his face. He did as she asked and layed across her lap atop the pillow with his head in the crook of her arm. With her free hand, Lexy took the soother out of his mouth and leaned over and set it on the coffee table. She put a bib over his chest. Then she put the nipple of the bottle to Luka's mouth and he took it in, sucking enthusiastically.

Lexy's heart was breaking for this man with whom she had been in love for over eight years. She was so glad she'd been able to talk him out of walking out on her. That would have been devastating.

Luka pushed the bottle away when it was about half finished. Lexy set it on the coffee table and got him up into a sitting position. She rubbed his back and gently patted it until he burped. She cleaned his face with a washcloth and removed the bib.

Frank had gone to his car and brought an overnight bag in. He took out a file folder, much like the medical chart he had brought. He opened it and took a piece of paper out, which was filled with printed out text.

“Luka, can you come back to being an adult for a few minutes? You can go back after we go over this.”

“Okay, Dr Frank.” He sat on the sofa beside Lexy.

“How do you feel about what has happened between us so far?”

“I love it, Dr Frank!”

“Good. So do I. Do you want me to keep coming around?”

“Yes, I do!”

“I have some ground rules you need to agree to. Most of them only apply when you are regressing. I'll read them over and you can decide if you can or want to follow them. Okay?”

“Do I get any input in them?”

“I will listen to any concerns you have and take them into consideration. But I have final say. Here are the rules:

1. You will call me Dr Frank, Daddy or Daddy Frank, whichever you prefer.

2. You will call Lexy whatever she wishes to be called.

3. You will obey both of us at all times. If you do not, consequences can be as mild as a time out or as harsh as a sound spanking. I tend to spank, Lexy may be more of a time out person. Except under extenuating circumstances, the person meting out the punishment will be the one who discovered the infraction.

4. You will be diapered at all times, regardless of what age you regress to.

5. When you soil your diaper, you will tell me, if I am here, or Lexy if I am not here. You will not go around in a wet diaper, it is not good for you. If you are non verbal, you will use gestures or cry to indicate you need to be changed.

6. You will allow me to have my way with you whenever I want. Same for Lexy - she can have her way with you whenever she wants. If you really are not feeling up to it, let us know.

7. You will never cum before either of us when we are having our way with you. Doing so will subject you to severe punishment. We will not make you ask to cum or forbid you from masturbating, though you should ask us for relief before doing the latter.

8. I will be your doctor whenever you need medical attention while regressing. If I am not here, Lexy will call me. If you wish me to be your doctor 24/7, I am willing to do that.

9. You will have a nap every day that you are regressing and it will be in the play room when you are here at home. If you are at my house, I will designate the room.

10. You may choose where to sleep at night, but when I am here for a weekend or more, at least one night you will sleep with me in the guest room.

11. You will be shaved at all times while I am here - face, chest, armpits, pubic area, testicles and legs. Your arm hair is light and sparse so I am not concerned about that. When I am not here for extended periods, you may grow it out if you choose. The hair on your head will be kept no longer than it is now.

“I will take care of you to the best of my ability while I am here or we are somewhere else. I care about you and will never do anything to you or ask you to do anything that will cause you harm. You need to trust me and do as I say. Or as Lexy says. She would never harm you either.

“Do you have any questions or concerns?”

Luka swallowed hard. “Do I really have to shave my chest?” he asked in a small voice.

“I love his chest hair, Frank”, Lexy said.

“Babies and young boys do not have chest hair, but I am willing to compromise on that, mostly because Lexy likes your chest hair. You may grow it out from October to April every year but it will be shaved from April to October. Also, you may let it grow out when I am not here during the summer months, but when I am here, it is to be shaved. I will shave you when I'm here. When I'm not, Lexy will shave the area that I insist be shaved all the time - namely your pubic area and testicles. If you choose to keep shaving your chest hair when I am not here, she will do that for you as well, whether or not you are regressing at the time, but she might choose to do it when you are a little boy. Anything else?”

“You said that when you are here for a weekend, I have to sleep with you in the guest room one night. I don't like sleeping away from Lexy.”

“One night during a weekend will not hurt you. The other option is that I sleep in the master bedroom with you two. You have a king size bed, you would be in the middle. Nothing would happen that all three of us didn't consent to.”

“Okay.” He turned to Lexy. “Are you okay with all this?”

“Yes, Luka.”

“What do you want me to call you?”

“You can call me Mommy Lex or just Lexy.”

“Are you sure, sweetheart? You're okay with me calling you 'Mommy Lex'?”

“Dr Frank suggested Mommy Lexy as a compromise. I think Mommy Lex sounds better. I'm willing to try it.” Luka smiled.

“If you are okay with this, Luka, please sign the paper”, Frank said to him. “Then you can go back to regressing if you want. This obviously is not a legally binding contract, it's just for our own purposes.” Luka took the paper, read it over and signed it. “All right, Sport, lets go to your play room. I want to check your diaper and get you shaved.”

Luka followed Frank to the play room. Lexy came along, too. Frank brought his bag and took shaving gear and clippers out of it. He removed the child guard from the plug by the bed and plugged the clippers in. “Lexy, could you get me a full size towel?” he asked. When she came back with it, Frank took it and laid it open on the bed. “Luka, please lay on the towel.” Luka layed down crosswise on the bed.

Frank undid the snaps on Luka's sleepers and felt his diaper. “You are wet, my boy. You didn't tell me you soiled your diaper.”

“I'm sorry, Daddy.”

“I'm going to let this one go because you just consented to the rules. But from now on, you let me know, understand?”

“Yes, Daddy.”

Lexy left the room and came back with a pail. “Here's a diaper pail, Frank”, she said as she set it on the floor.

“You sure did shop!”

“There's a lot more in the guest room closet!”

Frank took Luka's legs out of the sleeper and removed the soiled diaper. He had only peed. “When did he last have a bowel movement?” he asked Lexy.

“Yesterday, I think.”

“If he doesn't have one by tomorrow, we may have to do something about that.” He folded up the diaper and put it in the pail, then undid the rest of the snaps on the sleeper and slipped it off. Then he got a wipe and wiped Luka's genital area and anus. “Lexy, could you please watch him while I go wash my hands? Make sure that he doesn't roll off the bed.”

When Frank returned to the bedroom, he picked up the clippers, turned them on and clipped Luka's chest hair to a fraction of an inch. Then he did the same to Luka's legs, though his leg hair was not thick. “Okay, Luka, time for a bath. Let's go.” He took the can of shaving cream and razor with them.

In the bathroom, Frank turned on the water and regulated it. Luka sat down on the tile floor and played with his toes, like a baby would. “Where's his soother?” Frank asked Lexy.

“In the living room. I'll go get it.” She came back a moment later with the pacifier and Frank put it in Luka's mouth.

The bathtub had filled to an appropriate level. “In you go, Sport”, Frank instructed Luka. He got up and stepped into the tub and sat down. Lexy had disappeared but returned with a bottle of baby shampoo, a bar of baby soap and a new washcloth. Frank washed Luka's hair, then bathed his body. Finally, he had Luka lay back with his head on the edge of the tub. He sprayed some shaving cream in his hand, rubbed his hands together, then coated Luka's chest with it. He picked up the razor, dipped it in the water and began shaving his newfound 'son'.

Lexy watched with mixed emotions. She wasn't crazy about Luka being smooth chested, but Frank was right - a baby or young boy does not have chest hair and Luka wanted as realistic an experience as they could provide for him. She consoled herself with the knowledge that this was making Luka happy and that the hair would grow back any time the shaving was stopped.

Next, Frank shaved Luka's legs, having Lexy hold each one up in turn as he did it. Then he drained the tub enough to expose Luka's genitals. He had not shaved or been shaven since he had shaved for the appointment at Frank's clinic the week before, so he had grown out a bit. Frank carefully shaved him, first in the groin area, then his testicles. Luka got semi hard.

“Oh, my, it looks like my boy is getting aroused”, Frank said as he took Luka's cock in his hand. Lexy could see her husband's member grow to full erection.

Luka giggled. “Yes, Daddy”, he said around the soother.

“If you are good, Daddy might take care of that after we are finished with your bath. But you have to be really good.”

“Yes, Daddy!”

Frank reached up and took the shower hose off it's holder. He turned the taps on and pulled the knob that sent the water to the shower head. After regulating it, he began to rinse Luka off. “Stand up, son”, he instructed. Luka stood up and Frank finished rinsing him off. He took a big, fluffy towel that Lexy handed him and dried him off, then asked him to step out of the tub. They went back to the play room and Frank removed the towel Luka had layed on, then put down a changing pad. “Lay down, Luka, with your bum on the changing pad.” He took two pillows from the bed and put one under Luka's head and the other under his butt.

He put his hands on Luka's ankles and brought them up so that his feet were flat on the bed and knees bent. “Open them as wide as you can”, he instructed him as he pushed his knees apart.

He reached into his bag and brought out a tube of lubricant. Taking a glove from a box on the dresser, he put it on and squeezed some lube onto his finger. “Knees to chest, Luka”, he instructed. Luka complied. Frank rubbed the lubricant into Luka's anus, very slowly and gently. He squeezed more onto his finger, then inserted the finger into his anus, lubricating the inside.

Frank set the lubricant down and removed his glove, discarding it in the trash. H undid his zipper and pulled his cock out, then pushed Luka's legs down and got on the bed and straddled his freshly shaved chest. “Take Daddy's cock in your mouth and get it hard and ready for your ass.” He pushed the head past Luka's lips. Luka's eyes were wide. He'd never had a cock in his mouth before. But this was Dr Frank and he'd do anything for his doctor-daddy. He parted his lips and took Frank's cock head into his mouth. “Suck on it gently”, Frank instructed. Luka did as he was told. He could taste his daddy's pre-cum. So that's what Lexy tastes when she sucks me, he thought.

Frank pushed all the way into Luka's mouth, getting up on his knees to do so. He was very well endowed - more in length than girth, though he was not overly thin either. Luka's gag reflex took over as Frank pushed in. “Just relax, Luka”, he said. “Take all of Daddy's cock in your mouth.” Frank was getting harder as Luka sucked on him.

Lexy layed down and stroked Luka's hair. That seemed to relax him and Frank was able to get his whole member into his mouth. When he was ready, he withdrew it and got off the bed. He put a lot of lube on his cock, especially the head, then knelt between Luka's legs. “Ready, Sport?” he asked.

“Yes, Daddy”, Luka replied after removing the soother from his mouth.

“Do you want me to fuck you in the ass?”

“Yes, Daddy. Please fuck me in the ass.”

“I'm going to, sweetie. Put your soother back in.” Frank lifted Luka's legs and pushed them forward so his knees were to his chest. “Lexy, could you do me a favour?”

“Uh...sure...I think.”

“Could you please guide my cock into him?”

Lexy hesitated a moment, then said “Okay.”

“You don't have to if it makes you uncomfortable.”

“No, it's okay. In fact, I think it's kind of hot.” She got off the bed and leaned over it, taking Frank's cock in her hand and guiding it to Luka's anus. Frank pushed in gently.

Luka gasped. “Ow!”

“Relax, Luka”, Frank said to him. “It will help a lot.” He kept steady pressure on Luka's opening, pushing in very slowly.

“Ow, Daddy! Why are you doing this?”

“It will feel good in a couple minutes, sweetie. You have to go through a little pain to get to the pleasure. Remember I said to trust your Daddy?” His cock head pushed through and into Luka. “It will get easier now”, he said as he pushed his shaft in.

Lexy layed beside Luka again. She took his hand and said soothingly “It's okay, honey. Dr Frank would never harm you. You will like this like you did in his clinic. Remember that?” Luka nodded. She leaned over and kissed his forehead.

Frank began to thrust in and out of Luka, beginning very slowly. He let go of his legs and put his hands on the bed, one on each side of his head. Luka wrapped his legs around Frank's waist. Frank leaned over and kissed him as his thrusts got faster. Once he was sure Luka was past the pain and feeling pleasure, he pulled all the way out, then entered him again. Luka gasped. “Are you okay, sweetie?”

“Yes, Daddy. That felt really good!” Frank did it again and again before thrusting harder and faster. Luka's cock was rock hard and throbbing.

“Do you want me to cum inside you, Luka?”

“Yes, Daddy. I want you to cum inside me!”

“Ask me nicely to cum inside you.”

“Daddy, please cum inside me!” Luka was gripping Frank's arms with both hands.

“You're such a good boy, Luka. I'm going to cum inside you.” His thrusts were at top speed now. He gave one final thrust and the first spurt of cum entered Luka's ass. Then the next and the next. Luka had been holding off, remembering Rule #7 but as soon as Frank was finished, he let go and squirted cum all over his tummy.

Frank layed beside Luka on the opposite side as Lexy. Once his breathing had returned to normal, he got up and wiped Luka's tummy off with a wet wipe. He wiped his own cock off, then put it back in his pants before using a wipe to clean Luka's genital area and anus. Finally, he rubbed him dry with a towel before removing the pillow from under him. He got a fresh diaper and had Luka lift his bum so he could slide it under him. He rubbed cream into his groin area and bum, then powdered him before securing the diaper with the tabs.

“Let's get this sleeper back on you, then it's bedtime.”

Luka took the pacifier out of his mouth and said “It's Friday, too early.”

Frank looked at his watch. “It's 10:30, that's plenty late for a baby boy.”

“Half an hour more? Please, Daddy?”

Frank hesitated. “Okay, on the condition you go right to bed when I say to. Deal?”

“Deal, Daddy. Thank you!”

“You're welcome, Sport.” Frank finished doing up the snaps on the sleeper and Luka went out to the living room to watch TV.

“I see you are going to be a softie!” Lexy said to Frank as they began to tidy up the play room.

“Just wait until I have to discipline him. You'll see I am no softie!”

Lexy finished cleaning up the room while Frank went to the bathroom to clean up after Luka's bath. Lexy joined him when she was finished.

“Lexy, do you mind if Luka sleeps with me tonight?”

“No, Frank. Not at all. In fact, I recommend it. I think you two should have some bonding time.”

Lexy took the used towels and diaper pad to the laundry room, which was just off the kitchen. She'd wash them the next day. Then she put on a pot of fresh coffee but made decaf since it was late at night. When it had brewed, she took a mug out to the living room for herself and one for Frank. Luka was laying on the floor, half asleep.

“I was going to give him something to help him sleep”, Frank said from the easy chair, “but I don't think he needs it.”

“No, I don't think so.”

“I'm relieved, Lexy. I thought he'd be hard to settle down after the news I gave him.”

“I think the sex helped.”

“Yes, that's one of the reasons I gave it to him. I was hoping it would relax him. By the way, I have some news on the change table. I have a friend who's great at carpentry, he's going to build one for us.”

“Oh, that is great, Frank. What did you tell him you need it for?”

“The truth. I have some dirt on him that he doesn't want getting out, so he will be discreet. I'd like to get an adult size crib for Luka, but they are quite pricey - not that that's a problem, I just don't want to buy one just to find out that it's a passing fad for him. But I have an idea for something that can act as a crib for now. I might be able to get it tomorrow.”

“Oh, that's good, Frank. I'm sure Luka will love it, whatever it is.”

“I think that half hour is up. Luka, time for bed. In fact, I think I'll go to bed, too.”

“Yes, Daddy.” He got up. Frank got up and wrapped his arm around Luka, who was still half asleep. He guided him down the hall to the guest bedroom. Lexy followed. After Frank got him into bed, she leaned over him and kissed him good night and said good night to Frank. She tidied up the living room and turned out the lights before heading to the master bedroom.

Five minutes later, she crawled into bed and reached down between her legs and brought herself to climax remembering the sight of Frank fucking Luka.
