My name is Cathy. I’m a 43-year-old widowed mother. I have a 21-year-old son named Brian. I’m a rather tall, slim woman; five foot eleven inches, very long, dark brown hair that comes down to my waist, and dark brown eyes. Tennis and running have kept me in pretty good shape. I’ve been told I look like Eva Mendez, but I think they’re just being polite.

My son Brian took more after his dad...

He has coal-black hair and stands no more than 5’4”. He’s a little shy but has a very good sense of humor. Brian’s father was a very handsome man, and Brian got every bit of that and more.

There are only two obvious differences between Brian and his dad. Brian’s a very wide, stocky young man. Even as a young boy in high school, Brian was very well built; very defined. He played on the football team all four years in high school and now is a running back on his college football team.

His dad, on the other hand, was rather skinny and non-athletic. The other difference was less obvious to everyone but my sister and me.

My late husband, Jimmy, was a very good lover. We enjoyed a full and exciting sex life for a long time before a car accident took him from us. Jim’s penis was not very big, five inches at best when erect, but Jimmy knew how to use it well. It never gave me reason to complain. He would refer to his small penis as “The Washburn Curse” and would jokingly tell me how it was handed down through the generations from his great, great, great-grandfather, Jeremiah Washburn. He always made me laugh. I would tell him things like:

“It’s all I’ll ever need” or “I love the way it all fits in my mouth.”

I didn’t tell him these things to make him feel better. I told him because they were the truth. We never did anything TOO crazy, nothing that would wind us up in jail anyways, but I believe I willingly fulfilled just about all of his fantasies; at least the ones he’d told me about. I had even invited one of my girlfriends into our bed when we were first married. He’d told me he’d never been with two women at the same time and would love to try it. He had a birthday coming up and I made it one I’m sure he never forgot.

When he expressed interest in anal sex, I was reluctant but certainly willing to give it a try. I have to say, I was rather thankful for the Washburn Curse when we explored that avenue. The fact was; I loved Jimmy and I loved his penis as well.

Now when Brian was no more than a toddler, maybe three or so, it became rather obvious to me that Jimmy would not share the “Washburn Curse” with his son.

I can recall my sister and I would make little comments and jokes to each other about Brian’s penis at bath time or when his diaper needed changing.

“He’s gonna be quite the lady killer.”

“That’s quite the little package he has there.”

“I hope he grows into that.” Little remarks like that.

I bathed Brian until he was almost seven years old, when he informed me he thought he was too old to be washed by his Mommy. For the next few weeks, I inspected my son head to toe after he was finished bathing. Satisfied with the job he was doing without my help, I let him wash himself from then on.

Well―One evening quite a few years later, when Brian was about fifteen, I walked in on him in the bathroom. He was standing with one foot up on the tub and he was drying himself after a shower. Although it all happened pretty fast, my eyes went right to the thing hanging between his legs. Literally, I mean it. It was hanging. When I recalled the incident to my sister some days later, I remember using the word - Piñata.

It was easy to see that “The Washburn Curse” was going to skip a generation. From what I thought I saw, his penis was already quite a bit bigger than his father’s, and noticeably thicker as well... And Brian was SOFT! As a matter of fact, it was the thickness that had caught my attention in the first place. I was a bit taken back.

The incident reminded me of some pictures that my girlfriend and I had seen in a magazine when we were teenagers. My girlfriend, Cindy, had taken it from her brother’s room and snuck it to her room one night that I was sleeping over. The name of the magazine was “Too Big”. We were amazed by the pictures, but that’s another story entirely.

Anyway— Brian looked up and saw me gawking. I must have been standing there with my mouth hanging open.

“Moooommm!” He squealed and quickly covered himself.

I promptly apologized and shut the bathroom door. I stood outside the door with my hand still on the doorknob, shaking my head slowly in disbelief. I wondered if I’d really seen what it was I thought I’d seen. I couldn’t have, I told myself. He’s fifteen.

I know that as his mother, the size of his penis shouldn’t have concerned me. In my defense, in the beginning, I just wanted to know if my eyes were playing tricks on me. I was surprised that I was giving this so much thought, but I couldn’t seem to stop. I needed to know if what I saw was real or was it just something my imagination was bending out of proportion, so-to-speak. I began to wonder if maybe it was just the light or maybe the way he was standing. I mean, if it were as big as it looked, certainly I would have noticed something like that—around the pool—at the beach. I don’t understand why it was so important to me, one way or the other, but it was.

I found myself thinking about it a lot in the days and nights after that. I even found myself sneaking fleeting glances at the front of his shorts and his bathing suit from time to time to see if maybe I could see an outline or a reference to its size, but everything he wore was baggy. Perhaps it was more comfortable for him that way. I felt myself blush each time I caught myself looking; embarrassed that I would do such a thing, afraid someone might notice my interest.

I found myself ashamed at times that I was looking at my own son in such a way. I told myself that I was just trying to confirm what it was I thought I saw. I kept telling myself that I must have been mistaken, that there was no way that a 15-year-old boy could have such a ... such a big penis. But the more I tried to dismiss it, the more I dwelled on it and the more I needed to know.

It had even gotten to the point where I’d found myself standing outside the bathroom door once with my hand on the knob ready to barge in with the intention of catching another quick look.

I know how all this sounds.

Sometime later, just before my son turned eighteen, I’d come in from a late dinner with the girls and found Brian asleep on the couch in front of the TV in just a T-shirt and his boxers. I leaned over to wake him and tell him to go on up to bed. I was just about to tap him on the shoulder when my eyes drifted down to his boxers. I froze. Sticking out of the open fly was the head of Brian’s penis. It was about the size of a golf ball. My stomach flip-flopped. I covered my mouth with my fingers to muffle a gasp.

I felt so silly, like a nasty little girl, standing there peeking at a boy’s privates. But nonetheless, I wanted to see more. I glanced up to make sure he was asleep. I didn’t want to get caught gawking at my son’s dick again. This was nothing like barging in on someone in the bathroom. THIS would be hard to explain.

I felt my stomach get all jittery as I shifted my attention back to my son’s privates. I took a deep breath to steady myself and resumed my investigation. I call it an investigation ... But in reality, it was borderline molestation.

I felt myself flush. I was pretty shocked at my reaction. I felt a little light-headed as I realized this might finally be my chance to actually see it, all of it, and put this whole crazy, stupid thing to rest. Maybe it was the three Gin & Tonics I had at dinner. I don’t know, but I had to keep myself from giggling like a schoolgirl.

I bent over a little more and cocked my head to see if I could get a better look inside the slit of his underwear. It was no use; his boxers hid all but the tip. If I was going to see any more of it ... I was going to have to pull his fly open more.

I should have realized how deep into this thing I really was when “Opening his fly more to get a better look” was my answer to that particular problem instead of just waking him up, sending him to bed, and going to bed myself.

I looked to make sure he was asleep. I bit my bottom lip and slowly extended my index finger; moving it slowly towards my son’s fly. The closer my finger got, the more nervous I became. I couldn’t believe it. One more quick glance up before I carefully hooked my long fingernail in the slit of his boxers and gently, slowly pulled open the small slit.

My finger was so close to my son’s dick. Again, I had to stifle the urge to giggle. I moved my head a little to one side to allow the light from the table lamp to better light the area. I noticed that my hand was shaking quite a bit. I glanced up at Brian one more time. Still sleeping.

I could see inside his boxers a little better now. There it was; most of it anyway. “Jeeezzzz...” I whispered under my breath. I found myself comparing it to his father’s. Even soft, what I could see of it, was bigger than his father’s had ever been hard.

I saw what looked to be every bit of at least five inches of my son’s penis. It looked nice and smooth —you know, like a dick— and after all my efforts to confirm what I thought I’d seen more than 2 years earlier, I could now see that in fact, it had not been my imagination. His dick was pretty big and very, very thick ... fat actually.

“ ... And it’s not even hard...” I remember saying.

Evidently I said it kinda loud because suddenly Brian grunted and shifted his weight. As he turned, I pulled my hand back like the damn thing was gonna bite me. And when I did, I inadvertently slid my finger over my son’s penis. I was immediately aware of the contact. I quickly stood up, straight, rigid actually, and quickly stepped back from the couch with my hands to my mouth. I don’t know what was wrong with me. I was peeking in my son’s fly- STICKING MY FINGER IN IT WHILE HE SLEPT! – and for some reason, I was on the verge of giggling.

My first thought should have been to run out of the living room and up to my room in case he woke up. Maybe call some kind of 24-hour HOT-LINE or a support group or something. Did they have support groups for moms that poke at their kid’s underwear?

Anyway-All I thought about was, “I touched it!” I stood there trying to be quiet and still as Brian settled in with a long sigh. I stood frozen, staring, for what seemed like a long time.

As luck would have it, —Good luck? - Bad luck? - Dumb luck? - The jury was still out—. Brian’s penis had worked its way out through the fly of his boxers as he’d shifted positions.

I remember my mouth dropped open and I believe I might have stopped breathing.

I could see almost all of it. There was no question. There was no need for anymore confirmation. It lay over to one side, maybe a little more than 6 inches and as fat around as a good-sized banana.

I couldn’t help but wonder, “What if it was hard?”

For a split second, I started to think about how I could accomplish such a feat.

I shook my head, trying to shake the thought away and quickly took another step back to gather my wits. I couldn’t believe what I was thinking. Did I really want to see how big my son’s dick would get? Did I really want to see my own son’s cock ... get hard?

I wondered what I might be willing to do to make this happen. A hot flash washed over me as if I’d opened an oven door, and I realized that I had to leave.

Wow! It was somewhat sobering.

I was ashamed of myself for the way I felt. After all, suppose he was to wake up and find that his hard penis was sticking out of his shorts and that his mother was hovering over him. “My God!” I thought. How would I explain something like THAT?

I quickly and quietly left the living room and ran upstairs to my bedroom. I lay in bed until well after midnight, wrestling with my conscience, trying to get a handle on everything. I knew it was wrong, what I did, and the way I was thinking, but I couldn’t seem to help it.

Images of my father flashed in my mind. The smell of his cologne and bourbon filled my nostrils. Memories of inappropriate moments made me shiver, but oddly enough, made me warm between my legs.

I remember thinking how glad I was that I had had only three Gin & Tonics and what might have happened had I had the fourth one.

Jimmy had been gone for more than two years at that point in time. I tried to convince myself that maybe these thoughts and actions were a product of loneliness and that I was still missing Jimmy, but deep down, the more I thought about it, the more I knew there was more to it. I knew that somewhere along the line, I had somehow become obsessed with my son’s penis.

At first, I was troubled and embarrassed by the thoughts and images that seemed to work their way into my head. They seemed to bombard me with more and more frequency. The fact was, I wanted to see my son’s dick hard and imagined different scenarios that would get me what I wanted.

I reminded myself that such things were forbidden, morally wrong, but I also knew for a fact that these kinds of things happened all the time in all walks of life.

As time passed, I found that I’d become more tolerant, more comfortable with the things I thought about, even excepting, if not embracing them at times.

I found that late at night when I was alone in my bed, that somewhere along the line these forbidden thoughts and images turned into welcomed dreams and yearnings, even fantasies.

At first, I shamefully tried to suppress the urge but found it useless most times. I told myself that nothing would ever come of such thoughts and desires and wondered if my father had told himself the same thing. Before I knew it, these feelings led to masturbation and, to my surprise, some very intense orgasms. I was obsessed.

Except for the occasional glance or the fleeting feeling, I pretty much kept my dark fantasies to myself. It was August 19th, Brian’s 18th birthday, as a matter of fact, when all that changed.

It was early on a Saturday morning; I had just come in from a run and figured I’d gather up the dirty clothes and do a load of laundry before I took a shower.

I approached Brian’s bedroom door with an armload of dirty clothes from my room. I quietly turned the knob and took a step in as quietly as I could, hoping not to wake him.

To my disbelief, Brian was stretched out on his bed with his pajama bottoms pushed down past his knees. I froze there, mid-step. His eyes were closed, and I could hear him softly cooing, “Yeah, that’s it. Do it...” But my real attention was on what was in his hand. I stood there by the door in my running shorts and sports bra, an arm full of dirty clothes, and my hand still on the doorknob, and watched my son jerking himself off.

He was so into what he was doing that he never even noticed me standing there. I was unable to move or say anything as I watched him masturbating. I knew I should leave, but simply put, I didn’t want to.

There was no doubt about what I was seeing this time. He was more than just ‘aroused’. There was no “Washburn Curse” going on here; that was for sure. He was hard now, really hard. Once again, what stood out was the thickness of it. As I watched his hand moving up and down, it was easy to see that his fingers didn’t reach all the way around its thickness. He stroked it with one hand, and it was easy to see that at least three inches of meat stuck out past the top of his hand and at least as much beneath it.

“My God, it’s huge...” I thought to myself, and it WAS; almost to the point of being freakish.

I just stood there and watched as his hand moved up and down, up and down. I couldn’t look away.

“That’s it...” He moaned. “Do it...”

I had no idea how long I was standing there. I felt like I was in a dream.

I hadn’t seen a whole lot of dicks in my life, but I wasn’t a nun either. And outside of any magazines or the Internet, I had never seen a dick that big, that fat on any man ... let alone a 18-year-old young man. I stood there totally amazed as my son started to squirm around and moan a little louder, still completely unaware that I was standing there less than ten feet away. When his hand started moving faster, it became clear to me that he wasn’t going to last much longer.

I should have quietly shut the door and left. I should have been

thinking about how embarrassed both of us would be if he were to catch

me watching, how awkward it would be, but instead; the fact that I was going to actually watch my son cum seemed to govern my thought process.

Oddly enough, all I could think of was how much cum would come out of such a fat dick. Then he moaned something that I would have never expected. It simply floored me.

“Yeah, Mom ... Ga-head...” He moaned as he jerked off. “Ga-head- do it.”

“Oh my God!” I whispered―Out loud―and dropped the dirty clothes to the floor.

Brian’s eyes sprang open, and he quickly turned his head towards me. His hand had stopped pumping, but it remained wrapped around his dick. When our eyes met, he looked as shocked as I was. I just stared at him, dumbfounded and speechless.

“Mom!!!” He barked as he let go of his dick and scrambled for his pajama bottoms.

“I’m ... I’m so sorry, Brian!” I fluttered, just as embarrassed as he was. “I ... I...”

I tried to pick up the clothes and leave as he struggled to pull his pajama bottoms up. I gathered the clothes and stood up just as he swung his feet to the floor and dropped his hands into his lap, attempting to hide the bulge. Good luck there.

“I was just ... I came in to get ... I thought you’d be...”

I stuttered and mumbled nervously as I tried to apologize.

He looked up at me. The embarrassment poured into his face, and I could see the humiliation in his eyes. I felt so bad for him. I instinctively took a step toward him to comfort him.

“It’s OK...” I told him. As I stepped closer, Brian pulled back a little, forcing his gaze to the floor, unable to look at me.

I took a deep breath. “It’s no big deal, Brian.” I blurted out, trying to sound lighthearted and nonchalant. “All guys do it. Your uncle John did it all the time, excessively.” I told him, trying to make light of it all.

I recalled that when I’d walked in on my brother doing it, he’d had the opposite reaction. He had actually asked me if I wanted to watch him. I was 13. I told him I did and stood there beside his bed and watched him bring himself to climax.

“Not in front of his mom.” He whispered and turned his gaze towards the window. I thought what he’d said was kinda funny and couldn’t help but giggle a little bit.

“Well, yeah ... I guess he didn’t. But he seemed to have no problem doing it in front of me.” I told him.

“You’re kidding?”

“No―I’m not.”

I put my hand on his shoulder and rubbed it a little bit. “Your dad used to do it in front of me all the time too.” I confessed.

He turned and looked at me, kinda surprised. I shook my head, “He did.” I assured him. Brian sat there quiet and self-conscious.

“I’m really sorry I came in, Honey.” I whispered. —In hindsight, I wasn’t sorry at all.— “I thought you’d be asleep. I guess wishing you a Happy Birthday would seem kinda silly now, huh?”

“Yeah, thanks for the big box of ‘Embarrassed’. Just my size too.” He tells me with a forced smile. It was nice to see that he still had his sense of humor.

I smiled back. “Yeah, if your size is extra large, right?” I giggled, kind of shocked I’d gone there.

I couldn’t believe I’d said that to my own son. I meant to leave before I said anything else stupid, but as I reached the door, I stopped and turned,

“I’ll close the door so you can finish?” I said quietly with a light smile on my lips.

“Yeah, right. Like I could do that NOW!”

I tried to make it seem like it was no big deal―An everyday thing.

“Well, not to embarrass you any more than I already have, from the looks of it...” I nodded towards his lap. “... it’s kinda obvious that you need to finish.” I told.

He looked into his lap and saw that his hands did little to hide the bulge.

“MOM?”

“What? It’s just that you looked like you were about to... ‘You know’

... before I ruined it.”

“Mom!”

“What?” I couldn’t hold back my smile. For the second time that morning, I had caught him off guard. He seemed truly surprised that I was this nonchalant about the whole thing. But that’s what I was going for ... Nonchalant.

“God! How the heck do you know what I was about to do?”

“Because I was standing here ... watching.”

“WATCHING?” He almost shouted.

I bit my lip and shook my head apologetically.

He groaned and took his hands from his lap and covered his face.

As you might think, my eyes went right to the bulge in his pajamas.

“Did you...” He hesitated, looking for the words. I knew what he wanted to ask me.

“Yes, I heard you, Brian.” I told him quietly. “But that’s no big deal either.”

Oddly enough, it didn’t bother me that my son was thinking about me while he masturbated. As a matter of fact, I thought it was kind of flattering, but, understandably, it seemed to bother him that I knew.

“Oh my God!” He groaned, from behind his hands. “You’re kidding me?”

“No. And it’s OK, Brian.”

“It’s not OK. Why didn’t you just leave when you saw what I was doing?” He asked through his fingers, embarrassed to look at me now. He shook his head side to side, wishing he was still asleep, no doubt.

That was a good question. I wasn’t really sure what to say. I thought that maybe it might be better to put the spotlight on me, instead of him, as it were. So, with the hopes of putting him at ease some, I went with the truth.

“I don’t know, Honey. I’m sorry.” I told him. “I guess ... I guess I just wanted to watch.” I confessed.

Now I was the one having a hard time holding eye contact. I had said something I could never take back. He stopped rocking and dropped his hands from his face. He cocked his head a little to one side and looked up at me.

“You wanted to watch?” His voice was low and full of inquiry. He looked, and rightly so, confused. This had certainly taken a turn that I never saw coming.

I shrugged my shoulders, tilted my head slightly, and shook it ‘yes’ with tiny little embarrassed shakes. “Sorry.” I told him and shrugged again.

There was silence for a few long seconds. I felt funny, and I wondered what he was thinking, what he was feeling. I was afraid of what he might think of me now. He knew my brother used to do it in front of me. He knew his Dad did it all the time too. And he knew that I, obviously, didn’t have a problem with any of that. Then he shook his head, “Jeez,” as if he couldn’t believe it all. I watched as what I thought was a small smile crept onto his face. I was relieved to see it. His eyebrows went up, his bottom lip puffed out a little as he mulled it all over and absorbed it all. I watched, as he finally seemed to get a handle on the moment.

“Wow...” He finally said.

I apologized again and told him I knew that it wasn’t right and that I should have left. I just couldn’t seem to help it.

“Like I said, your father used to do that in front of me all the time.”

Brian drew his head back, “I don’t understand.”

“You don’t understand what, Sweetie?”

“Why would Dad have to do it? I mean ... You were married and all. Wouldn’t you have just ... You know?”

Then I stepped a little further out on that limb. “I asked him to do it.” I told him honestly.

“You ASKED him to? But why?”

“Wow!” I thought. I couldn’t believe it had come to this.

I thought for a second, looking for the right approach. Realizing that I’d probably said too much already, I knew I shouldn’t be telling him this, but I just blurted it out anyway. Sometimes I’m surprised that I walk around with enough sense to wipe my own ass.

“I just liked to watch...” I softly told him and then turned shamefully to leave.

I couldn’t believe I had actually confessed such a thing. I had said it out loud, and it seemed to make him feel a little better at any rate.

“Mom?”

I stopped. I could feel my stomach flip as I turned around.

“Yes, Honey?”

Then Brian said something that changed everything.

“If you really want, you could just leave the door open.” He said.

There was another long silence. However, this one was different. This one made me feel all tingly inside. It made me feel―Well―Like I was in high school again, and Billy Henson was feeling me up under the bleachers.

I was a bit stunned. A few minutes ago, I’d stumbled upon my son jerking off, and now―Well―I wasn’t exactly sure what was happening. All I really knew was that I didn’t have to wonder about the size of my son’s dick anymore. It was huge, and I had told my son something extremely personal.

Before I could stop myself, I blurted out...

“Are you saying what I think you’re saying, Brian?”

He smiled, “I don’t know. What do you THINK I’m saying, Mom?”

“I think you’re saying...” I felt my throat tighten. “... That I can watch if I want to.”

If that wasn’t what he’d meant, then I was making a big mistake. I wondered how this might change our relationship; whether he was saying what I thought ... or not.

“I guess ... yeah, that’s what I’m saying.” His looked as unsure as I no doubt did. His face flushed with color. “You can ... Watch ... if you want.” He whispered, like someone might overhear.

I wasn’t sure what to say. I wasn’t prepared to just pull up a chair and tell him to go ahead, although had he suggested it, I would have.

“I mean ... It’s no big deal, right?” He added quickly, struggling to sound casual.

I shrugged my shoulders, “Everyone does it.” I agreed as if we were talking about people taking a shit.

We looked at each other for I don’t know how long; maybe a second, maybe a minute, but I remember having a hard time breathing.

I sighed, long and hard, “Alright then...” I was flustered at this turn of events. I nodded. “ ... I ... I guess I’ll just take these clothes down to the washer and ... and throw them in the washer.” I didn’t even think to grab any of his dirty clothes. “Maybe I’ll come back up when I’m done.” The words were out and said before I felt my lips moving.

I took one final glance at his crotch. At that point, I guess I didn’t care if he saw me or not. The bulge was still very obvious, and he no longer tried to hide it.

In hindsight, I think he had other things on his mind. I couldn’t help but feel a certain measure of resolve. I knew now without a doubt what was in my son’s pajamas.

As I reached the doorway, I looked back over my shoulder to see if he was watching me. I pushed his door all the way open. Then I smiled,

“I guess maybe I’ll see ya in a bit.” I told him like a silly little high school girl. I turned and left for the laundry room.

I shook my head and tried to steady my breathing the whole way to the laundry room. “I guess maybe I’ll see ya in a bit.” echoed in my head. I couldn’t believe I’d said that. I told myself I must be dreaming as I threw the clothes in the machine. I set the dial to ‘Wash’ and braced myself against the washer as if it were filled with water. I may or may not have put laundry detergent in with the clothes. I had other things on my mind. I tried to get a grip on the whole situation. It might have helped to have a few more brain cells on the job.

“Is he really going to be jerking off if I go back up there?” I asked myself.

“Is he actually going to let me watch? — I shouldn’t go back —Does he actually want me to come back? — I know he does ... I heard him when he was jerking off. He was thinking about ME ... about me doing it to him. The thought made me warm all over.

It was amazing. I was literally trembling. The last time I felt like that, I was in Billy Stevens’ basement after school and he was trying to get me to touch his little dick. I told him I couldn’t because I was allergic.

I was actually afraid to go back to my son’s room. I was determined to do the right thing, the moral thing, but I found myself climbing the steps and walking down the hallway before I knew it. As I approached his doorway, I stopped. I was breathing sporadically; little, shallow breaths. I was shaky too, unsteady on my feet and yet, at the same time, I was having a hard time fighting off those goddamned giggles.

I thought about when Brian’s father used to jerk-off for me. I thought about the times I watched my brother doing it. I kept thinking, wondering, about how everything might change if I were to step through that doorway.

“You shouldn’t do this ... You’re his Mom...” I told myself but it did nothing to curb the excitement I was feeling about what I might see when I turned the corner.
