My girlfriend first big dick [F24] [Cuckold]

Me and my gf have a relationship over 8 years.
2 years ago i came up with the hotwife idea. She liked it so we roleplayed first for a while and then one of her friends was willing to fuck her for her first experience, she liked it a lot so had sex with him a few times. But she wanted to try something New and something bigger. So we found a dating app for hotwife etc. So we searched for a while to find a good guy. We met someone and talked with him and meet with him a few times. Then the day came that they have sex for the first time. He first showed us some pics of his dick so she could prepare. So they went on for it in the bedroom as i was watching and he was really big. She couldnt fit his cock in her mouth. So the moment came that he was about to penetrate my gf. He went in with his tip and slowly began to stretch her pussy, halfway in my gfs legs began to shake and she already had her first orgasm. And he was going deeper and deeper. And it seemed like her pussy was made for his cock it fitted so perfect. They had sex in various positions. Then he came inside my gf. After she had multiple orgasms. She told me that he felt so good. Now they meet up every 2 weeks. Sometimes every week
