My girlfriend and a stranger's ass

This story happened about a year ago, with my girlfriend we had arranged with a dude to meet up and see what happened, the idea was to get to know each other, take something, talk a bit and see if it worked out, how it turned out late directly we passed on looking for the car, first my girlfriend went ahead with me making a couple of blocks while talking and then to see what was happening we stopped and my girlfriend went back with the dude, we started talking about what he would like to do and what he enjoyed most during sex, it was noticeable that he was hot and I told my girlfriend to pay attention if his cock pleased her she started caressing a bit and it looked very comfortable so I asked her to show me and get out. We were surprised when I pulled out a cock of more than 25 cm and quite thick, my girlfriend looked very surprised the dude looked at it and asked if he liked it immediately she looked at me and said let's go to a hotel and started eating his cock in the car seat you couldn't see much but it was noticeable that she was trying hard and not getting anywhere near. We arrived at the hotel, went in and she didn't stop eating his cock the idea was to make a trio but clearly she was very busy so I went to the bathroom to be more comfortable when I got back I found her arched in front of him but not sucking it off just giving head kisses on the cock's head it was noticeable that she was in love with that cock, I couldn't believe what I was seeing my girlfriend arched in front of another man eating his cock like that at one moment the dude said suck my balls and grabbed his cock lifted it up and put his balls in her mouth she ate them with too much pleasure savoring and licking them impressively until the dude told her he couldn't take it anymore and wanted to screw her my girlfriend got down on all fours on the bed and I approached with condoms the dude asked me to bring a towel from the bathroom. When I got back, they were already screwing and it was clear that it was costing her to hold out all that cock, so I left them alone and dedicated myself only to watching like a dude who barely knew how his girlfriend was getting screwed by a cock worthy of a porn actor. It lasted very close to half an hour, she made him cum about 5 times, I felt like the king of the horned until a moment when he told her he couldn't take it anymore and needed to cum, a minute later the explosions were faster until he finally got it in deep, I got closer to see better and saw his cock come out whole without any condom followed by an impressive cum shot. At that moment, I looked at the table lamp and saw the closed box of condoms, then I looked back at my girlfriend who was lying on the bed with her pussy well open and full of cum. Very slut.
