My son and I have always had a very open relationship where I try to teach him that sex isn’t sinful or wrong and one day while we were watching TV together, a very erotic movie came on. I don’t remember exactly what the name of the movie it was anymore but the gist of the plot was about a divorced woman in her late 30s who remarries and falls in love with her own step son and struggles through social stigma, intolerance, and other prejudices just to be together with her step son. Eventually she divorces her second husband and marries her step son. 

And there were a lot of very explicit  sex scenes where the mother and son would be completely naked and were seen having sex together, sucking cock, licking pussy, and having sex in various very erotic sex positions, and they even explored a bit of BDSM and bondage. It was a European movie and I’ve been told it was very famous in the country where they produced it, either in Germany or the Netherlands. 

Anyway I was blushing the entire time I was watching it. My face was beet red and my stomach was churning, especially during the sex scenes, and when I turned to look at my son I could clearly see that he had a boner in the tiny underwear he was wearing. It was summertime and I was wearing a see-through chiffon with strap lace panties and no bra and my son and I were snuggled together on the sofa half naked and he would be using every opportunity to reach his hands under the sheer bottom of my chiffon and find my tits and play with them. I don’t stop my son when he wants to play with my tits, but I would gently pull his hand away when he touches my pussy.

I tried to hide it of course but I was very turned on by the movie we were watching together and during one climax of the scene, where the step son takes his mother to a BDSM club where there were lots of son and mother couples and all the mothers were submissive to their sons, being spanked, forced to kneel, and even hogtied and displayed, my son turned to me and asked me if “incest is wrong.”
I will be honest I haven’t had a nice cock ever since I got divorced a couple months ago and I’ve had my fantasies and my son has been the only constancy in my life now. The movie was almost an exact replica of my own sex life, filled with frustration, sexual frustration, emotional rollercoaster, bonding with my own son, loneliness, anxiety about aging, trying to be a good mother, balance between sex life and professional job, teaching my son about sex on my own, and … of course … the forbidden attraction that I seem to not able to know if it’s just pure platonic love or sexual lust and all I knew was my thighs squeeze together whenever my son touches me. 

I was blushing deeply and I said well, generally it’s wrong … but if it involved consenting adults … And having babies would be a huge risk … And … don’t you think it would be super weird?

He said maybe … maybe not … because didn’t the movie say that people used to marry their cousins in other non-western countries, and that incest is not really frowned upon in places like the middle-east and some other African countries? And then he talked about his own experience of how he read in his Bible classes on Sunday that daughters used to have sex with their fathers in the Old Testament, and sons married their mothers in the Corinthians. If incest is approved by Yaweh, then it’s not wrong. Also, incest is not considered a sin in the ten commandments.

I don’t remember what else he said anymore and he had a lot of more evidence to buttress his argument and it all involved religion but I feel we both kinda agreed in the end that it’s not wrong as long as it’s between consenting adults who loved each other.

At this point the movie was over and it was getting very late but the room was still very hot and humid and that was when my son said his underwear was bothering him and so he took it off and I saw his cock was fully erect and it was even bobbing up and down a little bit, like it was about to ejaculate at anytime. I didn’t say anything. I was merely looking at it. It was so nice-looking and so beautiful, just like the stepson’s cock in the movie we just watched. So I didn’t stop my son when he guided my hand and put it just above his cock, where his pubic hair was connected to his lower belly. I just rested my hand there and then my son asked me if I felt hot and encouraged me to take off my chiffon. I ended up sitting next to my son in my panties with my chest completely bare and that was when my son moved closer to me and started rubbing his cock against my boobs. 

I was getting abit scared and I told my son maybe that’s enough fooling around for one night and why don’t we go get some sleep. I went back to my own bedroom with my son’s precum smeared on my nipples and later that night I masturbated myself thinking about the movie. 

My son has always been very intimate with me. I have done many things with my son that would be considered very inappropriate but I promise I have never actually crossed the certain moral boundaries. I kiss my son. I hug my son. Just like every other mother. But my son and I also give each other massages and during those massages my son had slipped his fingers inside my pussy, but just a few times and afterward I always told him to not do that anymore and he is very respectful and he doesn’t do it on purpose. And there is one time where I asked my son to help me shave my pussy because I had a customer later that night and the customer liked me to have a completely bald pussy when I go meet him. Well, there are several instances where my son caught me having sex with my customers inside my bedroom or having an online session with some people but I haven’t done anything else beyond that. 

I love my son with all my heart and I know my son loves me too and I am willing to give him anything, and I would never want to refuse him anything either. But still, there are certain lines that I wouldn’t want to cross, but I also feel tempted. I don’t know how to feel about all this to be honest.
