The moment I knew I was a cuck [Cuckold]

I just wanted to share how I realized this about myself. It started on a beach vacation with my GF. We went to Mexico over Christmas. we had done beach things before but not ever in Mexico our out of the US. Idk what came over me but, seeing her in a bikini at a resort just sent me over the edge, I would always make her go order our drinks so I could sit back and watch her get looks and see if anyone would talk to her. IDK why I found it SO hot! Nothing happened that trip, but It for sure started something inside me. I started to encourage her to wear more revealing clothes and smaller bikinis etc.. She was a bit confused by my requests. finally I told her I just think the whole thing is really hot and she conceded and agreed just to dip her toe into my fantasy and send me a few thrills while I watch her flirt or something. overall It has been a great time but I always think back to that first time seeing her order drinks in Mexico and the convo the bartender was having with her and the group of guys asking her to play volleyball .
