I'm a 29 year old man, in a relationship with my 26 year old fiancé, we've been together for 4 years. 2 years ago I was the one who talked about the fantasy of having sex with another couple, it excited him a lot, but jealousy took over and we didn't talk about it anymore. Then 4 months ago I confessed to her that I no longer fantasized about making love together with another couple, but that my biggest fantasy was to see her with another man, just to watch her take pleasure or fuck her with one or more other men, she told me that it excited her a lot but only as a fantasy and that she doesn't want to realize it for real, but that according to her nothing is impossible in the future.

So for the last 4 months I've been making sub-questions to her, to which she responds or not, we bought a dildo that she let me choose, it's the Bandit by Vixen Vixskin, it's really big, and a bit longer than me, we've played with it several times but it's always me who's been on the initiative, she never suggested it herself, but each time she loved it, much more than she told me, because she had violent orgasms, fainted, and screamed in ways I'd never heard her scream, whereas the dildo was just half going inside her

there was hardly any back and forth movement, she mainly enjoyed the idea and the fact of being spread like she'd never been before. In all we played with it 4 times, 4 times when she had record orgasms in speed and, for pleasure I think too. During these moments of pleasure with the dildo there was 1 time out of 2 of role play imagining another man, but he was always imaginary and not someone she knew, and she always told me "it excites me a lot but never without you, I'm always yours".

I don't know if this is important or not, but my penis is 16m long and 4cm wide, in inches that's 6.29 inch long and 1.57 inch wide,

And our dildo is 7.47 inches long and 1.77 inches wide. (Vixskin Bandit)

She comes in 30 seconds with the dildo, as a missionary, without pushing it all the way in, and going slowly, so tight is she on it i think

Not long ago I spoke to her again about my fantasy during sex, but it seemed that she was only excited by the idea of me and me alone at that moment, as she told me, so I didn't persist

So sometimes this fantasy seems to excite her, sometimes she just want me.

I forgot to specify, I don't want to have a cage, I'm not submissive, nor am I deprived of pussy, but the idea of sharing it with one or more men, excite me a lot.

I need advices too on the way of how to bring the dildo during sex ?

At the moment, about 1 out of 5 intercourses, during foreplay, I open the drawer and take the dildo, saying "I want you to play with the dildo".
