"How big does it get, Tommy?" his mother asked in amazement. Susan's eighteen-year-old snacked in the kitchen, when the towel dropped from his body. After the initial shock of Tom's nudity, her attention focused on his large penis. Impressed with his massive member dangling soft between his legs, Susan wondered what her son's erection would look like.
"You mean once it is fully hard? Well, it was a little over eight inches, but that was last summer. I haven't measured it since then," he said. Tom noticed his mother's fascination of his hefty genitals and did not rush to cover his nakedness from her view.
"Oh Tommy, it has to be longer than that. Why, you grew at least two inches taller over this past year," she equated.
"You are right about that. My cock did get longer and a lot thicker, for sure. It depends on how excited I am, and how much I jerk on it, too," he coolly told his mom with his giant pendulum prick swaying toward her.
"I know you like playing with it. I hear you moaning and the incessant clicking of your cock while you stroke on it in your room." She did listen, and on more than one occasion, too. "How frequently do you...shall we say, take advantage of yourself, Tommy?"
"I play with my cock pretty much every day. It's cool, mom. My friend, Robert, said he jerks on his cock that often, too. He has a big one like me. But of course, you know Robert; he says his is bigger than mine."
Susan knew of her son's habit, for she stood outside of his bedroom on a daily basis. Tom's mother looked forward to the everyday eavesdropping. She wanted to watch him in person, but she could never allow herself to peep in his door. Frustrating her more was the arousing language uttered during his fantasies. Tom ordered to pleasure his cock. Susan ended up breathless in her own room, sprawled on the bed, with a pussy full of fingers, and desired to do everything he said.
"I like to read erotic stories or watch porn while I do it," he continued, "I will jerk for hours while reading plots with incest involved, and I watch underground videos with the same taboo theme."
Susan's heart raced at the thought that her son was into family sex; that he possibly wanted to make love with his sexy mom. She wore no bra or panties under her terry-cloth robe, and the sash loosened enough for him to get a glimpse of her breasts. She teased the boy with hopes of seeing his cock in a full throbbing erection.
"Tommy, your sheets and all my towels are stained from you ejaculating on them. You have a lot of semen for a young man of eighteen," she pretended to complain as she moved to sit in the living room. Tom followed, leaving the towel behind, and stood nude in front of his mother.
"My cum has to go somewhere, mom, and tissues stick to my dick. I can usually make it come four or five times a day. Is that a lot? I have not done it yet today, though, and I am horny, too. My nuts feel like they are going to explode," he said while squeezing the large pink orbs in his fist. She noted that he shaved his balls.
"I see just talking about doing it is making you get hard," she said, but Susan hoped it was from the sight of her breasts, as she let her robe fall open more. She stared in fascination at Tom's huge cock while it grew thicker and longer. It bounced only a foot from her face as it stretched and angled upward.
"It's not hard, yet. Do you want me to jerk on it and show you how stiff it can get? I can make it get real big and swollen, mom. Do you want to see? You can measure it for yourself if you want," he said and squeezed his heavy cock. Tom inched closer, as he stroked on it slow and easy.
"Tommy, what are you doing, honey? You should not be playing with your penis in front of your mother," she objected as thought a decent parent should, but now with the moral formality gestured, Susan became enthralled with watching him make it erect for her.
"How else is it going to get super hard? You're the one who wanted to know how big it gets," Tom reminded her.
"Well, just this one time, and it is for the sake of accuracy only. Okay, Tommy, you make it as big as you can, and I will put a tape on it," she gave him permission to masturbate in front of his mother. It also was an excuse for her to fondle the object of her fantasies.
"Oh cool!" Tommy said excited, "This will give me bragging rights over Robert's big dick. Maybe, he and I should have a competition with you being the official judge. Is it okay, if I while I do this, we watch porn, too?"
"We are just going to measure it, Tom. That is all. Do you understand? I do not want you saying anything about this, either."
"I won't say anything to dad or Cindy."
"It's your friend, Robert, and other boys that I do not want you blabbing to. Do you hear me, mister? You keep your mouth shut and don't tell anyone about what goes on in this house."
"Yes, mother," Tom agreed, but added in jest, "If that will open your sweet lips for my cock."
"You smart-mouth, little bastard with your big dick better not be getting any ideas. I am your mother, and you keep mindful of that," she raised her voice. She slapped him, too, as part of the parental charade, before she rushed to get the cloth tape from her sewing kit. Being in denial to this mischievous act, and prone to the ambitious notions of her well-hung son, Susan sat on the edge of the couch and watched while Tommy jerked on his big cock only inches from her face.
"This could take a little while, since you won't let me watch porn. Do you think it would be all right if you opened your robe a little more?" He could almost see her nipples.
