How did I get into cuckolding? Well my ex girlfriend made me get into it. we had been together for a few years and she had cheated on me a few time, and I had been very forgiving to her, which really just encouraged her to do it again. The third time she was caught out I walked in on her in bed with a co-worker and we knew that we needed to either go our separate ways or come to a new arrangement in our relationship. We talked it through for some time and she made it clear that she loved me and really didn't want to lose me, but also that we were not sexually compatible and she was not at all satisfied sexually with me. The options were to either split up or I turn a blind eye to her sexual activities. We agreed on the later and remained a happy couple for 4 more years. Eventually she fell in love with a man she had been sleeping with for a while. We both at this time had reached a mutual point where we both wanted to move on and go our separate ways. We hadn't had sex together for almost a year at this point too and she had asked me to move out of our shared bedroom into the spare room as her new lover found it too weird that we slept in the same bed. We stayed like this as a couple, but not for close to 6 months, before she moved in with her partner.
With the same girl, we went on holiday to Croatia (she is Croatian) and took advantage of the many beaches that you can sunbath naked. We found a place that was totally empty with not another person in sight and and went all out to be exposing out naked flesh and soak up the sun. After a few hours of naked swimming and sunbathing alone save 2 passers by, a guy came along the beach and started talking to my girlfriend who was walking about stretching her legs. He was naked, in his early 30's, had a great body and an impressive flaccid penis. They spoke in Croatian, which I didn't speak well, for some time. It was clear by there tone that they were flirting, and I knew better than to go over to them and cock block, so I lay still and bit my lip. Soon enough my girlfriend came over alone and crouched naked next to me. She nudged me to make sure she had my attention and said "hey babe. I've been talking to the guy over there, he's a really nice guy. We are going to go for a little walk 'alone', so don't come over and disturb us. We are just going behind the rocks over there where it's a bit more private. I'll be back soon babe. I love you so much". She gave me a kiss on the cheek and walked off with the stranger. They were gone for about an hour and a half, holding hands. She said goodbye to him and he kissed her in a rather sexual way holding her ass and a breast. She, knowing I could see them pushed him off her and presumably told him 'not in front of my boyfriend', as she was looking at me with a slightly apologetic look on her face. She came over to me and sat down beside me. I asked if she had a nice time, to which she replied in a truly grateful way "yes, that was really good. Thank you so much babe for being so good about this. I totally needed that. I will make it up to you later. You will get a really good blow-job!".
