I was working very late into the evening one night and I thought my son had already gone to sleep when I got home.

Instead I found the light in my son’s bedroom was still on. He was wearing a set of noise-cancelling headphones that covered his entire ear lobes and I figured he was playing video games again. I didn’t mean to pry into his private life. He is an adult and has his own life but I just wanted to let him know that he should put a blanket on because he was sitting at his computer desk completely naked.

I moved closer to him and, I don’t know if shocked were the right word, but I was definitely very surprised and gave out an uncontrollable gasp under my breathe.

My son was masturbating and on the screen was a naked Asian woman being tied up, suspended in mid-air, and she was being publicly displayed in front of a group of men outside a dilapidated house in the middle of nowhere.

My son was moaning, “Oh mom. I love you mom,” as men took turns using her body, slapping her naked butt, sticking their fingers inside her holes, and then eventually gang banging her.

I was watching the computer screen and then staring at my son in stunned silence, not sure what I should do, when suddenly he turned his head and quickly slammed his laptop cover closed. At first I thought he was going to be mad at me for spying on him, but he was more embarrassed than anything else, and I knew I was wrong in the first place so I quickly backed out of his room.

What I didn’t tell him was that my ex-husband, his father, was into the exact kind of things that my son was into. His father used to a big aficionado of SM and bondage and would tie me up into various very elaborate knots and he was very proud of the work he had done on me, often taking me out to BDSM clubs where he showed me off his other men and women, or taking photographs of me in different bondage positions.

“Like father, like son,” I supposed.

After our divorce, I’ve yet to find a man to ever practice what we used to do together. Also, I’ve been going to some support group for single mothers, and during one session, we heard a case story from a psychologist who said that sex education is the most important education for adult sons and she went on to explain why mutual masturbation can help bonding and growing together for both mother and son. I was very shocked by this at first but the psychologist explained that a lot of mothers practice it but are just too ashamed to admit it.

The next day I asked my son if he had ever fantasized about me in those porn scenarios and his silence told me more than any answer would have. The whole situation was actually quite endearing to me. My son was being vulnerable and open to me in a way that no man has ever been, at least not since my divorce.

Still a bit later, after we both had gotten over the most awkward phase, I told him that “Mommy was curious. Do you feel comfortable showing me some of the stuff you liked.”

My son was very shy about it, and I assured him that “Sex is nothing to be ashamed of. Mommy will always love you no matter what.”

So eventually he did. He showed me a collection of his SM photos, videos, and some also involved pet play, where the woman would be naked with nothing but a collar and leash around her neck, kneeling on the floor, and a man would be standing next to her holding a whip in his hand.

I asked him to pull up one of his favorites and I told him that we could watch it together. He was a bit hesitant. Again, I assured him that mommy wouldn’t mind it, so eventually he did.

He linked his laptop to the TV in the living room and we both sat on the sofa. The woman in the video was a mature Asian woman in her late 30s, her body shape looked almost exactly like me, and to be honest, I thought she was rather plain-looking. I was thinking, “I actually looked prettier than this woman in porno.”

The woman was being tied up, gagged, blindfolded, and collared. A man came up to her and started playing her exposed vulva. Then she was being spanked and she was whimpering in both pain and pleasure. Then she was released, made to crawl on her hands and knees until she was in another room where there were lots of men who were waiting for her. She was made to squat down, her hands up at her shoulder like they were paws. Then she was ordered to urinate into a bowl and she had to drink from it afterward. Then she was tied up again and all the men took turns fucking her.

I was fascinated more than turned on, because I was thinking to myself, “gosh golly my son is just like his dad,” and I smiled to myself as I thought about it.

And my son was getting very excited as he was watching the video, and he said he couldn’t control himself anymore and he pulled down his pants and showed me his completely erect cock.

I smiled and minced my lips as I watched my son being so excited and it just felt very natural at that point to ask if he would like to see me being like that, being tied up, spanked, and used by lots of men. And he replied with a resounding “yes,” with lust in his eyes.

I think he said it before he realized what he was even saying.

I pulled down my panties and kicked them off. Took his hand and placed it between my legs. Letting him rub my clit as we continued watching the woman in the video being gangbanged. I also put my hand on his dick and helped him masturbate. And within a minute or so, my son was shooting thick sprouting fountains of cum up into the air. It was just the time when I took him to the Yelllowstone and saw white liquid sprouting out of holes on the ground. They were hot, steamy, and, quite a stunning feat of Nature. I was giggling to myself. His cum was landing on the TV screen, on the floor, and some of it was smeared on the sofa and I ended up getting on my hands and knees and scrawling around on the floor scrubbing off all the cum clean with a tissue paper.

I have yet to tell my son that I was turned on by stuffs like that as well, or that I find myself imagining being the woman in those SM pornos that he liked.
