Brutally fucked by a stranger! Escalation and a guilty conscience

I actually just wanted to take a bath in peace. But I was overcome with lust and stripped nude. I fingered my pussy. Unfortunately, I wasn't alone, a stern voice from the background warned me that I wasn't allowed to be nude here. I should put my clothes back on and leave. I don't know who the guy was but he looked really good and I was just horny. I went all out and pulled his trousers down to see if his cock was as thick as his arms. I just started blowing. Lying in the water, I gave him a juicy deepthroat. I sit on the thick strap and ride him off, in the middle of the beach. My guilty conscience about my boyfriend quickly evaporates. I pull the guy into the bushes and let him fuck me really hard from behind. It's just marvellous to have sex nude in nature and then with a cock like that. He held out well but now wants to get rid of his cum too. Because I liked it so much, he's allowed to squirt in my face and mouth. He disappears again and I'm sitting there, covered in cum and now my conscience comes back to me - should I have done that?
