Caught getting off in public jacuzzi

Caught in the jacuzzi
(Some background information first) I'm about 5'10, my cock isn't a 9 inches or anything but it's about 7 inches and really thick. I've always had a thing for public stuff. When I was 10 my family and I would go to the river and at the river there is a jacuzzi. Well one day we went in it there were like five people in it. I was sitting down enjoying my time.. then it happen I turned around when my mom (who was in the pool across from the jacuzzi) called my name to tell me where she will be at. But at that moment my cock instantly felt the jet hit it. It felt so good, I couldn't stop pushing (I was humping it, but at 10 i thought i was pushing) into it. I only talked to my mom for about 10 seconds. So after that I didn't care I still faced that way with the jet pulsing my cock. It was the best feeling ever felt at the time. I was then getting off right in front of these people in the Jacuzzi, did they know what I was doing? Idk probably. But I didn't care I just kept pushing my cock against the jet. Then finally after about 2 minutes which felt like forever, I finally had an orgasm. I had no idea what just happen I was only 10 it felt amazing that's all I knew. So every day I went back to that jacuzzi and doing the same thing, most of the time I would try to make it like I was looking at something. Ever since then I loved the feeling of the water hitting my cock and getting off in front of people.

(Now the main story)
I was on vacation with my family we were staying at a hotel. At this point now I am 21. My mom and I decided we wanted to head to the jacuzzi. We get in the jacuzzi, there was no one else there just my mom and I. The jets were in a decent position for me to lay there and try to let them hit my cock. It was perfect everything was lining up, I was going to get off right in front of my mom! So I positioned myself, it wasn't the perfect set up that I had originally thought it to be because I didn't want to make it too obvious so I kinda just let hit my head a bit but that was doing it. My cock got hard instantly, the jets were hitting moving it all around. I just closed my eyes and enjoyed it. My mom started to try and talk to me I would make little replies here and there. But I was focused on trying to cum. My mom was laying across from me she is a DD, she was decently thick. I would call her a bbw. When I realized the jet wasn't hitting my cock in a good enough spot I moved slightly more towards the jet and it seemed like it was doing the job. That's when I got a better view of my mom who was closing her eyes and enjoying the jacuzzi. I was just staring at her tits imagining myself tity fucking her or having them in my face while she was riding me... that's when she said
"I know what you are doing"
I was shocked she said something, what was she talking about? Could it be she has caught me? I replied by saying "you know I am doing what?" Getting all defensive as if I'm not doing anything.
She opens her eyes and point to the jet. "You're using the jacuzzi jet to try and get off, aren't you?"
Omg she knows. At this point I sat up just I was about to say how sorry I was she said
"Uhhm you don't have to stop, I don't mind that you are doing that. After all I am doing it right now as well. I didn't know guys could do it too, until a few years ago I peaked in on you when you were taking a shower. I saw you using the shower water only to cum"
I was completely and utterly shocked my cock was rock hard. Was this really happening? It was surreal. It was then it hit me that she really was using the jets as well. She facing them letting them pulse through her pussy, and letting it hit her clit. At this point I️ was embarrassed and I️ wanted to hop out but I️ was so turned on already. The fact that my mom was right there fucking herself infront of me made me even harder. She started to slightly moan, at this moment I was just staring at her. She then moves to the jet close to me. She puts one arm on top of the jacuzzi and the other she starts to pinch her nipple. I️ could not stop staring at her, at this point I️ had my trunks pushed down full on humping the jet letting it hit my cock. I️ start looking around because for a moment I️ forgot we are totally exposed being outside. I️ saw a women walking up to the gate. So I️ nudged my Mom and she then pulled top back up and put her other arm on the side to but we were both letting the jets fuck us as the women luckily just went into the pool. My mom then turns to me and says “mmm the jet feels so good on my pussy, I️ love watching you get off” she then puts her hand in the water and grabs my cock i was so surprised. She then begins to stroke my cock up and down. It felt so good, but I did not want to cum yet I wanted this moment to last as long as it could. Then I bring my hand down to her pussy, she already had her bikini pushed down. I started to rub her throbbing clit, then I pushed my finger inside her and she let out a little moan. My mind was going crazy my mom jacking me off! And I am in public! My cock was so hard, I had to pull a away from the jet or I was going to cum. I insert another finger inside her and start fucking her pussy with my two fingers while I rub her clit. We are both in pure ecstasy and then the jets turned off. We both sitting there exposed. But I was able to see her pussy. It looked so good, I just wanted to put her on the side and fuck her with my tongue and my dick. We were both exposed but neither of us got up to press the button. So she just looked at me in my eyes stroked my cock faster and faster and I started to fuck her hard with my fingers and started to rub her breast. I couldn’t hold it anymore I finally BURSTED cum shot after cum shit right in the water. That then put my mom over the edge she then moans a little louder while throwing her head back “OH my fuuuuck, fuuuck that’s feels so good” we sat there for probably a minute with our suits still down but we were still out in the open! So we pulled our suits up and then got up and left. We went back to the room and dad was none the wiser.
