"The tip is huge. It must be the size of a big purple plumb." Carol told her son.
Josh stood before his mother with his pants at his ankles. Mother was on her knees, eyes glued to her son's 11-inch babymaker. Carol gazed at her son's enormous hanging ball-sack, where within two egg-sized testicles brewed billions of potent teenaged sperm. She traced the bulging maze of viens running up the thick, meaty stalk until she again beheld an engorged cockhead, indeed the size of a plumb. Carol had never seen a cock this big. She didn't know they could grow this enormous. Her husband's was 5-inches and although she could count the number of orgasms she'd had in her 20 year marriage, their sex life always seemed good enough. It was only now, as she gawked at a dick more than twice the length and girth of her husbands did she begin to wonder. Wonder if there was a place within her that her husband had never been.
"Mom, can you check?" Josh asked.
Carol snapped out of it. She had nearly forgotten why she had her son's big dick inches from her face in the first place.
"Sorry, sweetie, so you say there's a suspicious lump by your testicles?" She asked.
"Yeah, could you check it?" Josh asked.
Josh knew he had his mother in a vulnerable place. For years he had been dreaming of this moment. There wasn't really a lump in his sack, he just wanted to feel his mother's hands on his nutbag. He knew he was a lucky guy size-wise and he wanted his mother to see how much larger he was than his dad.
With shaky hands Carol took hold of the swinging scrotum and felt the weight of her son's balls in her hand. She couldn't believe how heavy they were. She could feel the jism sloshing around within the sack. Josh was in heaven as he felt his mother's tiny finger trace his mighty nuts, her nails digging into the withered skin.
"Everything feels normal. Can you show me where?" She asked.
Josh looked down at his mom. Oh how he longed to fuck his dick deep within her. How he longed to suck the nipples of her big, motherly breasts. He knew he could make his mother cum again and again with a cock his size, if she'd only give him the chance.
"Is mine bigger than dads?" Josh asked. He knew damn well it was, but wanted to remind his mother of this fact.
Carol felt a bit embarrassed for her husband. Not only was this boy larger, but over double his father's size.
"Well...yes, you could say that, but size isn't everything you know?" Carol said.
"Yeah, I know. I'm not worried though. I have incredible staying power." Josh said.
Carol couldn't believe her ears. Not only was her son amazingly large, but he had now confessed his ability to fuck until the cows come home. A woman's dream! She felt her labia split and drips of pussy juice trickle down the canyon, onto puckered ass-lips.
"Does dad have lots of stamina?" Josh asked.
Carol fumbled her words. She knew that a fuck with her husband usually consisted of a 2 minute hump until he came. She knew that her husband didn't have the size or the stamina to please her.
"Well...yeah, sometimes." She confessed.
"Do you wish he was bigger?" Josh asked.
Carol tried to think up a lie but could only mutter the truth.
"Yes." She whispered.
"Do you wish he had one the size of mine?" Josh added.
Carol smiled, glancing at her son's huge erection.
"Well, I would imagine ones that big are pretty rare. Not too many men are as lucky as you are." Carol said.
"I guess lucky wives are pretty rare too then." Josh said.
"I suppose you're right. Your girlfriends are very fortunate." Carol answered.
"Would you like to see what it's like, to have something this big inside of you?" Josh boldly asked.
Carol was speechless. It was not her imagination. Her 18 year old baby was asking her if she'd like him to fuck her with the biggest dick she had ever seen. A billion questions raced through her head. What if she were caught fucking her son? What if her husband found out?
"You mean, you and me...doing it? Josh, I...I mean you're my son and...Jesus if your father ever found out he's kill us both." She spouted.
"He won't find out. He works 30 miles away and doesn't get home for another 5 hours." Josh said.
"Yeah, but we can't--
"Okay, fine!" Josh said, pulling up his shorts.
"No, wait, what are you doing?" Carol asked.
"You're obviously not interested." Josh answered.
"Now wait a second, I didn't say that." Carol said.
"Then you are interested?" Josh asked.
Carol didn't answer, still sorting through her thoughts. Josh started to tuck his dick in his shorts.
"Yes, wait, I'm interested, please, Josh!!!" Carol shouted.
"Please, what?" He asked
"Please take it back out." Carol answered.
"Then what?" Josh asked. "Tell me what you want, mom."
Carol felt weak in the knees. It was her son, yes, but it was also the one time in her life she'd have access to a cock this size. She knew that she could never live with herself if she were to pass it up.
"I want you." She whispered.
"Where do you want me, tell me, mother." Josh said.
Carol swallowed hard.
"I want you between my legs. I want you inside of me." She said.
And this is how Josh's purple plumb started its amazing journey. The first phase of its adventure came only a few minutes after Mom and son's discussion, in Josh's parent's bedroom upstairs. Josh and his plumb were guided to the bed and soon found themselves between a mother's outstretched legs. The swollen plumb was directed to a fat hairy muff. The purple helmet slithered between two chubby lips, stretching them almost beyong their limit. The plumb traveled down a dark, creamy pouch, deeper and deeper and deeper, stretching the walls of this secret chamber for the very first time. Finally the plumb hit bottom, nudging against the doorway which it had traveled through only once before. The plumb's journy wasn't over here. It had another 2-inches to travel. Slowly, it burrowed its way through a tight ring at the back of this chamber until it gained entrance into the holy of holy's. A place where all son's once were, but few son's will ever return.
Carol had never been so stretched. Never been so stuffed full and would cum more in the next three hours than she had in her entire life up to that point. One orgasm every 10 minutes would rock her world, sending her into a screaming, quivering fit over and over again.
As for Josh, he and his purple plumb would plow the grounds of his mother's garden for a good hour before he blew his first load, bathing his mother's womb with a dozen ropes of creamy jism. He got to suck the big nipples of his mother's enormous boobs as they rolled up and down her chest. After that day, he knew he was hooked and Carol knew that her husband's little cock would never have a place between her legs again. It could never even scratch the great void that had been created by her baby's purple plumb.
