THE DOCTOR

BY

ROBERT GLYNN

I first met Mark at a leather bar downtown. He bought me a drink and said he couldn't help but notice the yellow kerchief I had in my back pocket. He had one, too. We talked awhile, and he ended up inviting me over to his house. I'm the kind of guy who often kisses on the first date. So was he. Actually, it turned out we both were the kind of guys who liked to suck cock, eat cum, drink piss, and fuck ass on the first date -- you know, a couple of very friendly guys. He invited me to spend the night. I told him I couldn't; I had to get home because my son was home alone.

"You married?" Mark asked.

"Widowed," I answered, "Seven years ago."

He said he was sorry, asked about my kid, and asked if we could get together again. I gave him my number, but never really expected to hear from him.

I did, however. In fact we became good friends and fun fuck buddies, something I really needed in my life. It was great having a no-strings-attached outlet for my sexual needs, and a release from my day-to-day life as an architect and single father.

Mark, it turned out, was a doctor, with a family practice. He liked to play dirty doctor, and so did I. He catheterized me, put speculums up my ass, gave me enemas and prostate exams, did colonoscopies, and some urinalysis' and other specimen collection' work that, I have reason to suspect, was never taught at medical school. We even got kinky enough to delve deeply into scat, something I've always loved, but to seldom get to experience. It was hot, hot, hot, and a lot of fun.

One night, as we sat side by side in his car masturbating, he asked me if I ever fantasized about having sex with my boy. I admitted the thought had crossed my mind, but I told him, I had never done anything like that.

Somehow, Mark's casual comment stuck in my mind. In fact, to tell the truth, it was about all I could think of for the next few weeks. I found myself looking at my son, David, in a different light; in a new, sexual way. I began to find ways to check on him when he was changing clothes or taking a bath so I could look at him. David is a beautiful boy and I found his naked body extraordinarily exciting.

I started to find ways to be naked in front of David, too. I wanted to gauge his reaction to his old Dad's `nads. I was delighted to see him checking out my junk, when I walked naked into his bedroom, drying my hair with my towel after a shower, to ask him about his homework.

I even went so far as to wrestle naked with David on his bed one night when I caught him about to change into his pajamas. I had my hands all over him, even letting my hand brush between his legs. I stopped when first David's cock, and then mine, grew rock hard. I wanted so bad to beat off, right there in front of him. Instead I told David it was time for bed. I also told him he was getting to be a big boy, and suggested it was time to give up pajamas and start sleeping in the nude, like I did. He was delighted, and waking him up in the morning became a lot more fun when I discovered he woke up with a piss hard-on most mornings.

Then one evening, I announced I was going to take a shower before I started making supper. I masturbated in the shower to reduce my sexual excitement and to make it easier to control my rod. After the shower, I stayed naked and started fixing supper. While we were eating David asked me why I was naked.

"It's more comfortable," I said, "and besides it's only us guys. You could go naked, too, if you wanted. It's fun." David grinned but there was no other reaction.

After supper, we watched a movie, me sitting naked on the couch with David, fully dressed, beside me. During the movie I noticed David kept checking out my crotch. The situation and David's attention was enough that, at a couple of points, I got excited and let my cock grow hard. It was so hot to sit naked on the couch with my boy sitting beside me, my cock erect, standing straight up and oozing precum. It was really a challenge to not touch myself. I wanted to jerk my cock so bad.

The next morning, I stayed naked while I woke, fed, and got David off to school. I masturbated as soon as he walked out the door. I often work out of my studio at home, so I stayed naked all day and was naked when he got home after school. After a snack, David went to his room to do homework, and when he came out, he too, was naked. It was a struggle to not fall on my knees and start sucking his cock.

After dinner I suggested another movie. We watched "Blue Lagoon", a film that features a beautiful girl and an even more beautiful boy, shipwrecked with virtually no clothes, on a tropical island. A classical example of the all too rare genre, G-rated smut.

This time, as I sat naked on the couch with my equally naked son beside me, when my dick grew hard, so did my boy's. We grinned at each other, and I put my arm around my boy and hugged him close to me.

My dick was throbbing hard and dripping precum through most of the movie, and I made no attempt to hide it. David was less turned on than I was, but he popped a woody a couple of times, and I even saw a few drops of boy precum. Later that night, when I tucked him into bed, I whispered in David's ear, "I like being naked with you." I kissed him good night and he whispered back, "Yeah, its fun."

When I called Mark that night for phone sex, something we did quite often, we masturbated while I told him about what I had been doing with David. Before we reached orgasm we had agreed I would bring David to Mark's office early Saturday morning for a medical check up. In the next couple of phone sex calls, Mark and I talked about David's exam, and what we would do.


Saturday, I woke David early and quickly had the boy out the door, and at Mark's office first thing. The office was usually closed on Saturdays so no one else was there. I introduced Doctor Mark and David, and Mark escorted us to an examination room. I took a seat and Mark asked my son to take his clothes off. David stripped down to his underwear, and started to hop up on the exam table.

Mark said, "You need to take off your underpants, too, David. You have to be naked so I can give you a complete male exam."

David looked at me, and I said, "Go ahead and get naked, son. You're a young man now and it's time to get everything checked out. Besides, it's only us guys here, and a male exam can be a lot of fun."

David grinned, pulled off his underwear, and stood before us in all his naked beauty.

"What a handsome boy." Mark said.

"Yeah," I said, "he really is beautiful, isn't he?"

David blushed, and I felt my cock grow hard. I glanced over at Mark and saw his pants were starting to show a bulge, too.

"Well," Mark said, "let's get started. David if you'll hop up on the exam table. Good please just lie back... now, bend your knees and spread your legs. That's good."

"Jim," Mark said to me, "if you'll bring me the rectal thermometer and the tube of lubricant from the counter, we'll begin."

I did as Mark instructed and stood close, watching as Mark coated his index finger and the thermometer with a jelly lube.

"David, have you ever had anything up your butt hole before?" Mark asked. David, with his eyes wide, shook his head no. "Well, that's alright," Mark soothed "however, in a male exam, we have to do several tests that require going up inside you. Don't worry though, it won't hurt; in fact, I bet you'll find that it feels good. A lot of boys really like having things up their butts, and I bet you will, too. I bet your Dad does."

I nodded and winked and said, "I do. It can feel really great to have something up inside you. Just relax and enjoy it." I thought I'd cream my jeans, watching Mark run his finger around my son's ass hole, and then slowly sliding inside the boy's pussy. I heard David inhale, and Mark said "Its okay: just relax. Pretend that you're going to the bathroom, taking a dump, and push out. That's a good boy." I watched as my boyfriend put his finger deep up inside my virgin son.

"How's that feel?" I asked.

"It's okay," David answered, "It feels funny, I feel really full."

Mark slowly withdrew his finger from David's ass. "Now let's get your temperature taken." Mark inserted the thermometer up David's shit chute.

"Jim," Mark said to me, "could you give me a hand here? If you would hold this thermometer in, I'll start the basic exam." I reached between my boy's naked spread legs and took hold of the thermometer Mark had inserted. "David would probably enjoy it more if you would move it in and out." Mark instructed.

I began to gently fuck the thermometer in my boy's pussy. "Does this feel okay, son? I asked.

"Yeah, Dad ... it feels kind of weird."

Mark , who had been palpating David's abdomen and chest, now took one of his nipples in each hand, and began to pinch and tug on them. "Well the nipple erector action seems to be working correctly," Mark said, "His nipples are getting nice and hard."

"That is not all that's getting hard," I chuckled, and with my free hand reached over and stroked my boy's cock, which had been quickly growing under the attention of this delightfully perverted medical exam.

"Dad!" David exclaimed with a shocked tone.

"Oh, that's all right," Mark interjected as I boldly continued to masturbate my son, "It's perfectly natural to get a hard on during your first male exam; all boys do, in fact some of the test were going to do, require you to be hard. So don't worry David, your Dad understands. Don't you Jim?"

"Sure I do," I answered, continuing to jack David's now fully hard penis, "my Dad did this for me at my first male exam." I let go of David's dick and saw Mark release his nipples.

Mark said, "Let's check his temperature." I pulled the thermometer out of David's bung and handed the instrument to Mark. "Perfectly normal." Mark said "Now, we need to get a few specimens, let's start with a urine sample. David do you think you can pee for us?"

"Uh ... sure, I think I can."

"Good, then why don't you stand up?" Mark helped David up, and handed him a specimen bottle. David looked at Mark, and asked incredulously, "You mean you want me to go right here?"

"Sure," Mark answered, as though it was the most common thing in the world to ask a naked boy to piss in front of an admiring audience, "I need to monitor all your body functions. And why not? It's only me and your Father here. I'm your Doctor and I'm sure your Father doesn't mind. Do you Jim?"

"No, no, not at all." I replied. "Go on David, just pee, its cool." David looked at me, grinned his naughty, little boy grin and nodded his head.

"Okay, David," Mark said "go ahead; give us a nice big specimen." This was so hot, I couldn't believe it. I thought I was going to blow my wad in my jeans, watching my beautiful young son fill the glass bottle with his golden stream of urine.

"All right," Mark said when David had finished, "any more in there?"

"No," David answered "that's everything."

"Good, now we need a stool specimen, so if you'll get back up on the table, turn around, squat, and spread your legs."

David said, "A stool specimen, you mean you want me to poop?"

"Exactly," Doctor Mark answered, "I need a sample of your feces, poop as you call it, and I need to watch and see how you produce it. A doctor can tell a lot about a boy's health by observing how and what he produces when he poops.

"Dad?" David appealed this latest indignation to me.

"Now, come on David, you need to do what the Doctor asks, its just between us, and it's not like I haven't seen your shit before, hell, I use to wipe your butt when you were little. "

"Dad!" David said again.

"Tell you what David," Mark said "if you'll shit for us here in the office, you can watch when it's your Dad's turn." Mark turned to me and continued, "You do want a complete male exam today, don't you, Jim?"

"Yeah, I think it's time I had one," I said "David, would you like to watch me take a shit in a little while?"

"What?" David asked, not fully comprehending the outlandish offer I had just made him.

Mark answered, "That's right, after your exam we're going to give your father a full exam and you'll be able to watch him have a bowel movement. Not many boys ever get to see someone else's excrement coming out of their rectum, much less watch their own father do it, and it's really quite interesting."

David looked at me and said, "Would you really let me watch you poop, Dad?"

"Sure Buddy, you can watch me, if I can watch you." I answered.

"Okay, so come on now, hop up and turn around," Mark said, as he helped David up on the table and put his hands on David's hips and turned him, till his back was toward us. "Now squat down." David did as he was told, and Mark picked up a plastic container and slid it between the lad's legs.

"Go ahead," I said to my boy "go ahead and shit, let's see you push out a big turd."

Doctor Mark rolled his exam stool directly behind my boy and leaned in close so he was only inches away from David's ass. I stepped closer to Mark, put my hand on his shoulder and leaned down as well.

I don't know how to tell you about the sexual thrill I got from watching my naked son squatting there on the exam table, shitting in front of my boyfriend and me. It was hotter and more perverted than anything I had ever done, or even dreamed of. I saw his little, hairless, pink, ass hole push out, saw it widen and open, and then saw the tip peak out of his anus, as his big beautiful, brown, turd began to slide out.

When David had pushed out two or three inches of shit, I couldn't help but think it looked like a hot, perverted, cock, hanging out of his ass, and I wanted more than anything to go down on it, to go down on my son's turd and blow it like I'd blow a man's cock. I couldn't believe how beautiful my son's turd was. I wanted to kiss it; I wanted to have sex with his shit. Fuck, I wanted to make love to my son's turds. I swore to myself, right then and there, that before long I would be having sex; a long, slow, hot sex encounter, with David's turds.

Right now, however, while I didn't have the time to fully make love to my son's shit; I knew what was coming next, because Mark and I had planed it. When the boy had finished and dumped a big pile of shit in the specimen container, Mark picked the container up and handed it to me and said, "Good job, David, beautiful specimen. Jim if you could take this to the lab for analysis, I'll clean your boy up and we'll proceed with the examination."

I swear I felt a rush of jealousy at the thought that it was my boyfriend who would get the honor of wiping my son's shit smeared hole, but we had agreed and, after all, even though he had the boy, I had the boy's turds. I left the examination room carrying my son's shit, turning as I walked out the door, to see Mark wiping David's pretty, pink, hairless, bung hole.

I quickly went to Mark's office, closed the door behind me, and ripped open my pants, shoving them and my underwear down around my thighs, and began to stroke my hard, aching cock. I set the container of shit on Marks desk, and picked up one of my son's turds. It was firm, almost hard, and so incredibly sexy. I shoved it into my mouth, bit off a mouthful, and began to chew my beautiful son's shit. The powerful taste flooded my mouth and brain; I swallowed David's shit and then crammed more in my mouth. I chewed and swallowed the entire turd while masturbating and with the last bite in my mouth, blasted a huge amount of cum, spattering my sperm all over the remaining turds in the specimen container. It was the most powerful orgasm of my life. I tell you, any of you father's out there, you should try masturbating while you've got a mouthful of your son's shit, it's incredible. It was the hottest sexual experience of my life.

I quickly tried to put myself together and get cleaned up. I had to get back to help with our perverted medical exam. I stepped over to the sink washed my hands, rinsed my mouth. I pulled my pants up, and stuffed my still hard, cum dripping, cock into them. I glanced at the remaining cum covered turds and thought how much fun Mark was going to have later on.

When I slipped back into the exam room I saw that Mark had David up on the examination table on his hands and knees in the classic dog style fuck position, Mark had inserted his finger in my son's anal fuck hole and was saying, "... that's it, right there, that's the prostate gland, it makes most of the liquid that shoots out of your dick when you masturbate. You do masturbated don't you David?"

"Uh, sometimes," David said.

"Well you should, at least every day. Two or three times a day is better. It is important to exercise your male glands -- your prostate and your testicles." Here he reached down with one hand and tugged on my boy's balls while he finger fucked his ass hole with the other. "When do you beat off, David?"

"Um ... sometimes at night before I go to sleep."

"Well, that's good, but I want you to masturbate more than that, though. Feeling your prostate, I can tell you need to stimulate your hormones. After all, you're becoming a man now.

Jim," Mark said to me, bringing me back into the conversation, "I think you need to make sure David is masturbating at least three times a day for the next couple of weeks, so we can strengthen his proper sexual development."

"Okay Doctor, if you think that's necessary," I said.

"I do indeed. David, maybe you can masturbate first thing in the morning when you wake up, or after you do your homework in the evening, when you take your bath, or while you're watching TV in the evening. Do you think he can do that, Jim?"

"I'll make sure he does, Doctor."

And David, I don't want you to worry about jacking off if your father is around. He'll understand, I'm sure your father masturbates regularly."

"I do Doctor, two or three times a day, every day."

"You do, Dad?" David asked, while Mark continued to play with the boy's balls as he finger fucked him.

"Sure," I answered, "I jack off when I go to bed at night, and usually once or twice a day, while you're at school."

"So, you see," Mark said, "you've got nothing to be ashamed of around your father. He does it, too, all men do. I masturbate often, myself, it's natural. Maybe you two can masturbate together."

Marked continued, "There's something else I want you to do ever day, in addition to regular masturbation. That's prostate and testicle massage, like what I'm doing now. I think that will be just the thing to ensure you grow into a healthy, strong man, like your father. Jim, I want you to come here, and I'll teach you how to do this, then I want you to do it at least once a day, twice a day would be better, for the next two week, till our next appointment, okay?

"Sure Doctor," I answered.

"Good, now take hold of your boy's testicles and rub them like this. That's right, very good. Now, tug them a bit, not too hard, just enough to stimulate them. Good. How does it feel to have your Dad massaging your testicles, David?"

"It feels okay."

"Great, now Jim let's grease your fingers up." Withdrawing from my son's cunt, Mark lubed my fingers with surgical gel and then said, "Now slide up into your boy's rectum." I slipped my middle finger into my boy's shit cunt and stroked his hot little cum gland.

"How's that feel, David?" Mark asked.

"It feels good. It kind of makes my penis tingle."

"That shows your Dad is hitting your prostate gland and that's good, but Jim, I want you to massage David's entire rectum, so I want you to move your fingers in and out more and massage all around, stroke every part of David's anal canal. Good, that's just right. Now I want you to do that for fifteen minutes at least once a day, twice a day would be better, okay?"

"It's okay with me Doctor," I responded while sliding my fingers in and out of my handsome boy's beautiful turd box.

"How about with you, David is it okay for your Dad to work with your rectum and testicles like this every day for the next couple of weeks?"

"Sure, I guess," my boy answered, and I knew then it was only a mater of time till I would be eating David's cum, and having sex with him and his shit.

Doctor Mark said, "All right, now I have one last part of the exam, so Jim, if you could come out of your son's rectum for a minute, and David if you'll lie down on your back.

Good I see your penis is nice and hard. You like having your Dad fingering your anus, huh?

Jim, if you'll go back into David's rectum and really work on his prostate, I'll masturbate him to collect a sperm sample."

I finger fucked my boy with two fingers, really working his cunt, at the same time that I fondled his balls. Mark took David's cock in his hand and began to stroke him off.

"That's good," Mark said, "you just lay there and let your Dad and me get you off. Does it feel good, David?"

"Yeah," David moaned.

I knew it would only be another moment before my son blew his wad. I slid a third finger up his shit chute and finger fucked him deeply. With my fingers in the boy, I could feel his orgasm beginning even before he moaned out loud and spurted jism all over my boyfriend's hand and his own belly. I kept fingering his shit cunt till the last drop of his boy cum oozed out.

"Very nice," Mark said "that's a healthy sized sperm load. Now let me collect a sample, and then we'll get you all cleaned up.

I cleaned David's pussy with a moist wipe while Mark collected as much of David's sperm as he could get into a Petri dish and then wiped up the rest of his boy sperm. I wished I could have licked him clean.

"Okay," Mark said turning his attention to me, "it's your turn, so why don't you get out of those clothes. David you might as well stay naked, watching a male exam is pretty exciting and you might want to masturbate. Remember, it's all right to beat your meat in front of your Father from now on."

David flashed his mischievous naughty boy grin at me.

I said, "Sure, stay naked if you want, I like being naked with you, and I know Doctor Mark likes looking at you, too. If you want to play with your cock, go ahead. Remember the Doctor said you're to masturbate at least two times a day from now on."

"More if you want," Mark added helpfully.

I quickly striped out of my clothes, and stood naked in front of my boy and my boyfriend. My cock, of course, was hard, sticking straight up, and moist with pre cum.

"I was going to get a urine sample first," Mark said, "but, are you going to be able to pee with your cock hard like that?"

"Sure," I said "I'll just have to relax for a second or two; I've always been able to pee with a hard on." Mark handed me a specimen jar, I bent my cock down and, as my son and my lover looked on, I filled the container with my hot yellow urine.

"That's great," Mark said taking the urine sample from me and setting it on a counter "now if you'll get up on the examination table and squat with you back toward us we'll get a sample of your feces."

As I climbed up on the exam table, I saw Mark take my son's arm and steer him to the exam stool, "Why don't you take a seat here, David, that way you'll really be able to see up close." Mark set a specimen container between my legs and bent down close behind my son and pushed him even closer toward my exposed shit hole. "Have you ever seen your father's anus before, David?" Mark asked.

"No." David said.

"Well you're a lucky boy, there are a lot of fathers that would never give their sons the chance to check out their bodies, and your Dad has a great body, doesn't he?"

"Yeah." I heard David answer with a note of wonder and admiration in his voice.

"His anus is especially nice, I think, here let's get a better view." Mark reached around David and placing a hand on each of my cheeks I felt him spread me wide open for my son to see. "Just look at that shit hole," Mark said "let's see if we can get that opened up a little."

I felt Mark place a finger on either side of my anal ring and slide in just a little to spread me open.

"Wow," I heard my naked son say "I can see inside him, it's pink."

"Push out just a little, Jim, let's find out how far we can see up inside you." This was a game Mark and I had played before when we had done scat scenes. I relaxed my anal sphincter and pushed down a little at the same time as Mark stretched my pussy lips wider."

"I see it, I see it!" David cried out.

"What?" Mark asked unnecessarily.

"I see Dad's poop!"

"Oh yeah, I see it too. Come on Jim, push it out, and show us your turd, show it off for us." I loved how Mark was shifting his language from medical to sexual terms. I pushed down and felt the shit slide out. I've had enough practice doing scat scenes to have enough control to make it last. I stopped when I figured just the tip of the turd, maybe an inch or so was hanging out of my ass. I knew I could hold that for a while.

"Wow," David said "look at that!"

"Yeah," Mark said "it's hot looking isn't it. You like looking at your Dad's shit don't you David?" Your cock is sure hard, and dripping wet. It turns you on, huh?"

"No ... uh, I mean ... its okay and all but ... I've just got a hard on, I get them all the time," my son stuttered. I knew he was embarrassed to be exposed as turned on to this wildest of all possible sex scenes, to be revealed as aroused by his dad's turds.

"Its okay, David," Mark said "I think your Dad's shit is really sexy myself; my cock is hard, too"

"It is?" David asked, and he sounded relieved to find out someone else felt like he did.

"Yeah," Mark assured my son, "I'm as hard as a rock. Why don't you go on and beat off if you want to, it's okay with your Dad and me, we understand it's a turn-on to watch a guy dump a big load. Then, speaking to me he said, "Come on Jim push out and give us a show, let David see some more of your shit."

I did as Mark said, and grunting, pushed out until maybe four or five inches of turd was hanging out my ass hole, I held it like that.

"Wow," Mark said "look at that, that's a really nice turd; it's even bigger than your hard cock, David, it looks kind of like a cock, too, doesn't it."

I was thrilled, when I looked behind me, to see my darling son, openly masturbating as he stared intently at my turd. My own cock was hard and oozing cock slime. I reached down and started stroking off, too. I pushed out the rest of a perfect big, brown, turd, maybe twelve inches of hard, solid, shit.

As my son watched, beating his meat, I pushed out two more small turds. "I think that's it." I said.

Just then David moaned out loud, and as Mark and I watched, he blasted another load of teen boy cum, just as large as his first wad, onto the floor.

"Alright," Mark said "it's obvious you get off on watching your Daddy take a shit. I'll bet he'll be happy to let you watch him dump any time you want, won't you Jim."

"Sure, Doc," I said "David can watch me anytime; maybe he'll let me watch him take a shit, too."

"How's that sound David?" Mark asked "You can watch your Dad dump a load of turds, while you masturbate, anytime you want, and you can show off your turds, while your Dad beat's off."

By this time David was recovering from his orgasm and, I think, coming back to earth embarrassed to find himself naked, a string of sperm dripping from his still chubbed up cock, and sitting in front of a huge pile of his Father's shit.

"Uh... I don't know..." he stammered, "I guess so... I don't know. I mean, is it really okay to do that? It seems kind of, you know, weird."

"Sure, it's okay David;" I reassured him "we can do what ever we want for each other, we're family. Why not? We're both guy's and we both have sexual needs, right? The Doctor says it's alright, and it's nobody else business."

Mark turned the conversation in another direction by saying, "Okay guys, we've got some more test to do here, so let me take this sample to the lab," here he picked up the container with my shit from between my legs, and handing David a couple of moist wipes, continued "David would you help by cleaning your Father up for me?"

The Doctor was out of the room before David could respond, and I just stayed their squatting on my haunches on the examination table, slowly stroking my hard bone, and waiting. Tentatively, I felt my son's hand, holding the moist wipe, dab gently at my butt hole. He took the wipe away and I saw him look both at the dirty wipe and the lips of my turd box, and then felt him return to my anus and more vigorously clean my dirty hole, even going so far as to push slightly into my sphincter. I tell you, every father should experience the sublime joy of having his son wipe his shit smeared ass hole. I hope, some day, your son will wipe your shit hole. I hope, some day, soon, my son will be using his tongue to wipe mine.

When Mark returned, he told me later, David was standing there behind me staring intently at the shit smeared wipe in his hand. "Okay David, you can dispose of that wipe in the bio-waste container, and let's check your Dad's prostate; Jim why don't you lay down on your back on the exam table."

I did as the Doctor ordered, and laid there, my hard wet bone sticking proudly straight up in front of my son and my boyfriend.

"All right we need to take a sperm sample and check out your prostate as well, so Jim if you'll spread you legs I'll go up in your rectum, and David would you like to help collect the sperm sample by masturbating your Dad?"

"Um, sure I could do that." David said. Then, taking my cock in his hand, my only begotten son began to beat his old man's meat; it was a heaven that only got better when Mark began to finger fuck me.

The scene was to hot for me to hold back long, after only a couple of minutes, I groaned and said, "Oh fuck David, that feels so great, jack my cock. I'm going to cum! Fuck, I'm cumming! Jerk my cock boy!" I blasted a huge load of sperm that shot high in the air before splashing back down and covering my belly.

After David let go of my penis, Mark pulled out of my ass and said, "Now let me collect a sample of your semen, and clean you up and then you two can get dressed."

As we dressed the Doctor said, "Alright, now David remember I want you to make sure you are masturbating at least two times a day, and three times a day would be better. Jim I want you to perform your son's rectal, and testicular massage at least twice a day. Don't forget, it's important for David's development."

I reached over and ruffled my boy's hair, "We won't forget, will we David?"
