I sought out my friend's daughter's OF account and feel disgusted with myself

For obvious reasons I will not be sharing it before anyone asks. I'm not looking for understanding. I'm absolutely disgusted by what I did. I'm well aware it was gross and creepy and I'm utterly ashamed of myself. I'm a married, middle aged man. I've known my friend for decades. Her daughter is 19 and, as such, known her for her whole life and had never looked at or thought about her in a sexual way even once before. Without going into all the details I found out about the account through disapproving gossip. I got curious, made a deliberate decision to seek it out and found it, with an excuse to myself I was just curious. But if I'm completely honest with myself, I wanted to see it. I made an effort to find it. I made an account and subscribed to it. Obviously I knew what kind of content is posted on that site but it still took me by surprise seeing explicit content of her. I knew I shouldn't be looking at it but I did anyone. I won't even try to sugarcoat the situation. I masturbated over her. It felt wrong but I couldn't resist. Pretty much as soon as I'd finished I was hit with shame. I felt like a disgusting pervert and closed it immediately. The next day I did again, felt even worse after and haven't touched it since. I'm certain my wife would leave me if she ever found out. I feel like I'll never be able to look at the young woman in question in the same way again. My friend would most probably never speak to me again. And I would fully understand why. I'm a disgusting, creepy old man. If there's any silver lining to all this, it has completely changed how I view pornography. I'll be completely honest and say I never viewed the women in porn as anything other than sex objects. The last time I looked at any, my view changed completely. I saw a young woman who'd grown up with hopes and dreams of a successful life. A woman who had been a bubbly girl who loved animals and dreamt of being a vet one day. A girl who never would've imagined she'd wind up doing sexual things in front of a camera for dirty old men like me to pleasure ourselves to. It felt gross. I couldn't get an erection and haven't looked at porn since. Anyway, that's my confession. I know it's vile but I had to get it out. As I said, I'm not looking for justification or understanding. In fact, if you also find it disgusting and gross or think I should rightfully be ashamed of myself then I fully invite you to tell me so. My final thoughts, to any young women here who might be considering it, just remember you have no idea who may view it.
