Nancy and her son, Ben often slept together, but until recently it had been an innocent, if not quite normal relationship. The two of them started sharing her bed soon after Ben's father moved out of the house. Nancy saw nothing wrong with this arrangement, even though the boy was well into his teens. He was her only child, and the most important thing in her world.
Everything went fine during the first few years, but as Ben grew older, Nancy began to notice some changes - in his and her behavior. At eighteen he had matured into a handsome, young man. He had also developed some grown-up interests at bedtime. He obviously enjoyed watching his mom whenever she changed into her nightgown. For several weeks now, he would lay on the bed, wearing nothing but a pair of thin cotton undershorts while she disrobed on the other side of the dimly-lit room. Even though she always faced away from him, Nancy knew she was presenting her attentive son with a brief but provocative view of her lovely, naked ass. His immediate reaction was an massive hard-on, which he never tried to hide from her. The routine never varied. Nancy would quickly slipped into bed, give him a kiss on the cheek, and cut out the light. Neither would say a word.
This continued until Ben turned nineteen. They celebrated his birthday by going out to their favorite restaurant, and then to a movie. Even though it was a school night, Nancy was going to let him stay up late. They returned home around 10 O'clock. She shuddered slightly upon entering the chilly house. It was winter, and she didn't like the cold. Ordinarily, this time of night they would have just gone on to bed; but tonight was special. As Ben plopped down on the couch, Nancy turned up the thermostat. Soon it was a toasty 80 degrees. The two watched television for a while, before Nancy suddenly reached over and switched it off. Ben looked at his mother and asked if anything was wrong.
"No, Honey...but I do want to talk to you about that movie we saw."
The film was an R-Rated feature which Ben had picked out. Some of the scenes included nudity and some fairly intense love-making.
"You know, that's not the kind of entertainment I approve of...but since it's your birthday, I decided not to object."
"It's not like it was pornography, Mom."
Ben knew that she wasn't really mad at him. She was only acting like a concerned mom.
"Well...some of it was pretty darn close," she responded. They both laughed, but then she got serious again.
"Ben...I don't want to embarrass you, but... ..I think it's time we had a little talk about, well...the two of us. I mean, ummm...our sleeping arrangements."
"O.K, Mom. I guess you're right. We should talk about it."
"I realize that most boys your age don't sleep in the same bed with their moms. It's just that we're so close...and I love you so much. That's the reason I don't go into the bathroom to change into my gown. I mean...that would be admitting that there's something nasty going on. Do you understand, Honey?"
Ben didn't know if he understood or not. He merely nodded, and wondered what she would say next. She looked so pretty sitting there, with her wide grin, sparkling eyes, and short, dark blond hair.
"Of course, there is one thing." She hesitated for a moment before continuing. "It's...Oh well, I don't know any other way to put this. It's the way that big dick of yours sticks up every night."
Ben was thrown off guard by her bold statement. A few seconds passed before he could say anything.
"Shit, Mom...I can't help it. The way you look...standing there with nothing on. I mean, its so quick, and I've only seen you from the back...but...you have such beautiful legs...and a great...well, you know."
Nancy was clearly enjoying the strange new course that their conversation was taking.
"I see...So you like your Mommy's nice, sexy butt, do you? I'm glad...because you are my special young man, and all I want to do is make you happy...O.K?"
"Sure, Mom...you're the best mother in the whole world."
Nancy gave him a full, hard kiss on the lips. She then whispered into his ear.
