Going out clubbing turns into my girl at a glory hole [Cuckold]

My girlfriend is 23, she moved in with me a few years back from Mexico. We haev done a few things to spice up our sex life and it's been great.

One weekend we went out to a local club, she wore a tight pink dress, no underwear and high heels, she pose for me and I took a few pictures. When we got to the club it was vibing, a bunch of what it looked like college crowd mostly. We got a table and my girl started drinking, I didn't drink as I was driving.

We danced a little bit to some 2 step country music and others, towards the end of the night she asked me to get her another beer, so I headed for the bar, it was crowded and only a few bartenders, 10 mins passed when I returned with the beer but my girlfriend was not at the table, I looked around and then I saw her in the dance floor grinding on some guy, the music had changed to reggeaton, the guy looked like in his early 20s, my girl was leanning a little bit and had her ass pressing agaisnt the guy dancing up and down as he grabbed her ass and thighs from behind. Occasionally she would look my way and hold a stare like look at me what I am doing, It turned me on so much all I did was stare. She danced like this for about 15 minutes until I think the guy came in his pants as he excused himself to go to the bathroom.
My girl came back and kissed me,chugged her beer and said let's go.

On the way home she was telling me how horny she was, she dared me to take her to a glory hole, I didn't hesitate. As we pulled in we read the rules and headed to a room, she stripped naked off her dress and got close to the hole, immediately a soft dick showed up, my girl started stroking it, the hands of the guy on the other side started grabbing her tits and body. She got on her knees and started giving a bj to the guy, I told her to not to make him cum yet, I took out a condom from my wallet and handed it to her with a smile on my face, I stepped back to the corner so I could masturbate while watching her go to action. She put the condom on the guy with her lips then she turned to me so her ass was pointing at the glory hole, the guy started fingering her a little bit then he grabbed his dick and tried to put it inside my girl but it was not going in so my girl had to help him, she leaned forward with her knees close together and ass to the hole as close as possible so the guy could go deep while fucking her. I was thinking the guy at the club wished he was fucking my girl like this while they were dancing. So the guy at the hole kept thrusting his dick inside my girl as she was working hard to keep her ass almost glued to the hole on the wall. The guy finally came and left in less than a minute. My girlfriend went over to me with her ass in the same position so I could stick my dick in her, as usual at this point I am balls busting so I just put my penis inside her and with her warm wet pussy I start to come from the excitement of what I saw.

As we walk towards the truck my sperm starts to come out of her wet juicy pussy and she tells me to touch.
