My girlfriend (let's call her Melanie) and I were 23, living abroad by ourselves, and before we went home, we decided to travel around Europe for over 3 weeks because who knew when we'd have the opportunity to do so again. Going into this Europe trip, I'd expressed to her how badly I wanted us to enjoy ourselves on this trip, and that she should take full advantage of it. Fortunately, this didn't take very long. My girlfriend is an absolute catch. She's 5'5", has beautiful caramel skin, is a real flirt, stunning eyes and smile, but her real attraction is without a doubt, her size H tits. Yes, she's a bit of a bigger woman, but this never seemed to hold her back because of her pretty face, charisma, and of course these tits.
So, we begin our trip in Europe, it's day 2 and we discuss how much interest we have in hooking up with other people, and she's slightly hesitant. I understood this as it was a new city and it was just us, but as soon as it was day 3, she was on Tinder and immediately found plenty of guys. Of course, she seems like a cute, busty American who is looking to hookup. "Casual dates, show me the city, etc" all the lines men want to see when they want to fuck someone.
We're relaxing at our hotel bar, a few other guests that we've seen over the last couple of days are lounging around and we're all chatting. Melanie texts me, "I found someone...he's hot". I feel my cock stiffen in my pants and text her back, "so go have fun ;)". I've told her that if she wants to hookup with a guy on her own, that she can absolutely do that. I know some guys won't want me to come and watch, so if she wants to go on a fun date and hookup with a hot guy, I'm all for her doing it. However, she's not necessarily on board for it and makes sure that they're comfortable with me coming before the conversation gets too far. So she keeps texting him, the guy is totally on board with cucking me, he enjoys the thought actually. What's even better is he was a solid 7 minute walk away so we decide to head over.
