Camgirl Aunt

I have an aunt, or technically a half-aunt since she's my mother's half sister. I've always had a crush on her, she's unbelievably gorgeous and desirable. And she's much younger than my mother, so she isn't that much older than me (I'm currently 20, so she should be around 35 or something).
It was all very platonic until over a year ago. I'm into camgirls, OnlyFans and the like, so every now and then I pay something to watch some pretty girls and jerk off to them. Thing is, I was shocked when I saw a live video of my aunt, under another name. My first instinct was to log off and call it a night, but I stopped. I had the house for myself and... she was fingering herself so good. I gave in and started jerking off to my aunt herself. I pictured my fantasy, her kissing me deeply and riding me as she moaned, and then I came the hardest I've ever had from masturbating (had to clean up much more than usual, tbh).
I felt very guilty afterwards, too much to look up her videos again. The guilt got worse the first time I saw her after that. I was all fidgetty and nervous, couldn't look her in the eye... and she noticed. It went on for a couple more times, so one day, during a large family gathering at the house of one of my uncles, which is big and has many rooms, she took me aside to his office and asked me if something was wrong. I tried to deny everything, but she insisted and kept asking because obviously I was a terrible liar.
Eventually, I confessed: "I saw one of your videos on the internet". She went pale as I said that. And then I blurted out: "It was hot".
She went from panic, to anger to exasperation and back again. She didn't say anything to me, she walked around the room with her hands on her head, talking to herself. She told me to shut up the two times I said I was sorry.
Suddenly, she stopped in front of the door. I thought she'd storm out. But no. Before I could say anything, in like a second, she locked the door and in a blink of an eye she was sitting on my lap, french-kissing me. When I tried to push her away she hugged my neck and hushed me. "Just go with it", she whispered into my ear before kissing me again.
And so I gave in. I was instantly hard and I could feel her rubbing herself against me and moaning. I tried to unbutton my pants, but she stopped me. I figured it would only be a dry hump, But she kissed me so deeply and moaned so sweetly I didn't care. In my mind I was fucking her, and that was better than anything I thought possible.
We were far along when she told me "now take out your cock". She figured I must have been close to cumming, and she started to masturbate me and suck me off. "Let me know when you're about to cum", she told me between licks. I was in heaven. She sucked me like a goddess.
"I'm gonna cum", I said as quietly as I could. But that went out the window. The second I climaxed, she took my cock whole down her throat, swallowing everything. I went mad in pleasure, and I let out some very loud moans. If there hadn't been music at the gathering, everyone in the block would have heard me.
I was still gasping for air when she licked the last drop of my cock, cleaned her lips, then looked me in the eyer and told me: "Whenever we meet again, we will only talk for formalities, and that's it. I don't want you to contact me, I don't want to know from you, and I don't want you watching my videos. This won't happen again".
Then she stormed out. I had barely finished getting my pants back on when I heard her saying her goodbyes to everyone. I couldn't catch up to her, I only saw her get on her car and drive away. That was, effectively, the last time I saw her. There were no other gatherings after and she didn't visit. Then the pandemic hit, so I haven't really seen anyone from my family since.
Today, I have honored my word and haven't searched for her videos. I do, however, jerk off to her Instagram, since she hasn't blocked me. They're very tame pictures, tbh, but they help bring back the most pleasant memory I've ever experienced.
