Dad Fucked My Girlfriend

This took a few tries to type up properly, sorry for the wall. Trying to write it out like this, it sounds dumb and obvious and just makes me even more mad, mostly at myself for letting it happen... Anyway! My girlfriend turned 19 a few months ago and I've been super paranoid that we'd get targeted and in trouble or something after hearing all those horror stories of other young couples getting reported for underage sex and ending up on some sex offender list for the rest of their lives. We've already done a couple things together, mostly touching and she's given me a couple hand jobs, it's not like I'm not pent up and horny myself but ever since she turned 19 I told her we'd have to wait until I catch up. Just to be safe. She kept trying to tempt me since then until about a week ago. Saying how it was okay because she's 19 now but I've seen the horror stories and it almost never goes well for the guy regardless who was whatever age.

With no warning at all, she is suddenly fine waiting until I become a legal adult and has no interest whatsoever beyond hanging out. Which had me suspicious about her and my friend at first because he kept telling me how hot she was. So when I randomly got an offer to go home early from work I took it for once, I was just going home to get out of my work clothes before 'surprising' my friend with a visit when I hear thumping coming from dads room. At first I assumed my dad was back in the game, I was impressed and relieved. But then I heard her voice. I can still hear it, calling him 'daddy' in that high pitched tone of voice she had when I would go down on her. I got so angry, I was worried I might do something I'd regret so I just... Left. I just ran in one direction, thinking about how I could probably make it to the next state over and start a new life living with mom.

I guess she had left before I got back. Dad was sitting in his bathrobe in the living room. He heard me come in that time and told me to sit down. He looked right at me as he told me that he saw me come home early from work on the door bell camera and he saw me run out the door shortly after. Dad told me what happened, that my girlfriend hadn't just been trying to tempt me since she turned 19. That he loved me, and didn't want to hurt me, but that he was a man with needs that haven't been met in a long time and my girlfriend was very eager to show him any chance she could how I've been neglecting her untouched pussy. He sat down next to me and showed me some of the pictures she had sent him. I wish I thought to check the time or date of the first one, I'm curious now if she gave my dad first dibs after hitting 19...

Dad told me that he respected my choice to wait until I was an adult, even if he didn't share the sentiment. That if he were me he'd be fucking her all over the apartment now that it was just us guys living there but that he agreed in "today's social climate" it was probably safer to jerk off alone in my bedroom while he took care of her needs until I become an adult in nearly 7 months. He has no interest in dating my girlfriend nor trying to take her from me in any meaningful way but he was going to keep fucking her regardless of whether we broke up over it. I was devastated but not in the normal way? It was just a lot to take in, I guess? Overwhelmed I guess would be a better word. It didn't help that he was rock hard sitting next to me, made it a lot more awkward.

I was tempted to call her and dump here right then and there while he watched but dad said something profound to me in that moment. That the one thing he regretted in life, when he married my mother, was how seriously his generation understood sex. How much shame, guilt and fear he associated with it, how he let those social stigmas come between him and past friends and girlfriends in ways he wished he could go back and change. That maybe he wouldn't be divorced right now if he wasn't so petty back then. That he hoped I would take life more casually and not fret over the little things like sex and other peoples success. Which, at the time meant so little to me, considering what he just did, I basically stormed out at the time. I haven't spoken to him or her in day or two... Now that I'm writing this out and thinking about it more calmly, maybe he was right. If I dump her and move in with my mom then I lose my job and a relationship I've been in for years. Is starting over worth it? Am I a coward for considering staying? Am I an idiot for letting her get away with fucking my dad behind my back?

I think I'm going to give whatever this is a try... See where it leads and if I don't like it I can still nope out any time. There's a lot of guys that like being a cuck, maybe I'm one of'em? It feels weird to think of my dad like this but it's not a bad weird yet. Maybe I just want to see if they'll let me watch her get fucked. I don't know, I'm overthinking this already. I'm just going to do it and see what happens like I normally do.
