"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.
