Cucked my boyfriend by kicking him out of his own bedroom

Context: Last year, my bf (now fiancé) admitted to me that he liked the idea of cuckolding. I was hesitant at first but soon warmed to it, I began frequently tell him fake stories to get him off, like how I wanted to blow guys I found hot. I never did anything in person, but then I downloaded a dating app and things changed quickly.

The night in question - I found this guy on tinder who was shredded, 6'3, and had a huge cock. We started chatting and he was very forward, making me very excited. My bf was asleep next to me and I didn't know what to do as we hadn't yet agreed on what was allowed, but I was so horny and I didn't want to miss this opportunity.

So I quickly cleaned up the flat, put on some slutty lingerie, and then woke my bf up. He was confused as it was like 2am, so I said "you need to go into the spare bedroom and close the door", so he went into the spare bedroom.

The guy arrives and we sit down in the living room chatting. He starts putting his hand on my leg and moving closer towards my 🦋 so I take him to the bedroom.

We fucked hard for over an hour. I have never been so wet and so turned on. I thought his dick would hurt, but my pussy stretched more than I thought it could. He came 3 times, 2 inside condoms and 1 in my mouth.

Eventually the guy leaves and I open the spare bedroom door. My bf has been listening through the thin adjoining wall and has come all over himself.

I make him clean up the lingerie and pick the condoms off the floor. I gave him a wet (very cummy) kiss, he returns back to his own bed, and we go to sleep together.

The hot guy even let me film so I can fantasise about the whole thing.
