I orgasmed from my son giving me a massage

This happened a few days ago, and I've gotten over the shock of it enough to want to share the story with someone, but this is obviously not the kind of thing I can tell my friends about.

I've been pretty stressed from work lately, and my son offered to give me a massage to help me relax. Now, I should clarify right off the bat that this was a totally normal, non-sexual massage. I was dressed, wearing a tank top and some small pyjama shorts. I was face down on our couch, he was standing next to me, not straddling.

The massage started off quite normal and nice. He worked on my shoulders, neck and upper back, and I was very relaxed. He started moving his way down to my lower back, and that's when things got a little... heated.

As he started pressing on my lower back, fairly aggressively, my clit started rubbing on the couch. It's a little hard to describe the mechanics of it, but my waist was essentially over the seam where two cushions meet. My clit was perfectly positioned over the edge of a cushion, meaning there was a fair amount of pressure. He was essentially making me hump the couch, inadvertently.

It immediately sent a little wave of pleasure through me, but I thought that he would move on soon enough and that would be it. He didn't, though. He stayed on my lower back, and if anything, increased the pressure he was using, making my clit rub more and more on the seam. I was getting seriously turned on.

At this point I should mention that I am in a serious dry spell, sexually, that's lasted years. I divorced my husband almost 10 years ago, and can't remember the last time I've had sex. Probably 4-5 years ago. All this to say that as sad as it is, my son giving me a totally innocent massage was the most "action" I've had in years.

I was getting perilously close to the point of no return, and at that point my brain kicked in and reasoned that I should tell my son to move on from my lower back, to my legs or something. I opened my mouth to talk twice, but both times all that came out was a little moan, more like a whimper. I just couldn't get a word out, let alone a complete sentence.

The orgasm built up really quickly. Once I realized I couldn't speak without moaning, and that he wasn't changing his technique, I resigned myself to the inevitability. I was going to cum.

My clit kept rubbing rhythmically on the seam. I knew what was going to happen. I felt the wave build up, and after one final push to my lower back, I was over the edge. I held my breath so I wouldn't moan out loud and let him in on what was going on with me. It took all my strength and concentration to stay quiet.

It was genuinely one of the best orgasms of my life. Maybe the best, if I'm being honest with myself. After the waves of pleasure receded, I started breathing again and caught my breath. It's a good thing he couldn't see how flustered I was.

Soon after, he worked his way down to my legs, and eventually finished the massage with a foot rub. That gave me a bit more time to compose myself, which I was grateful for.

After he was done, I thanked him, trying to act as normally as possible, though my voice was shaking and I was still beet red. He didn't seem to notice anything wrong, though, or if he did, he hid it well. I made my way up the stairs to my room, my legs feeling like jelly.

Once I got the door closed, I collapsed on my bed, trying to process everything. I had to change my panties, as the ones I was wearing were completely drenched. Seriously, I've never been one to get very wet, but these were soaked through.

I avoided him for the rest of the evening, as I felt really awkward around him, but the next morning I felt better. I can at least act normal around him.

He offered massages "any time" I want them, and it's been hard not to think about that lately. On the one hand I'm extremely embarrassed that I actually came in front of... because of my own son, but on the other hand, I can't stop reliving the orgasm, and how strong it was.

Anyways, thank you for reading my confession,

An embarrassed, worked-up, horny mom.
