¿ Cual es tu fantasía? (Cuckold)

This is more than nothing for new people since many already know me. Tell me what fantasy you most frequently have with your wife, friend or lover. I have the fantasy of seeing my wife with someone else, maybe she only gets excited following along. She always tells me not to be afraid to say what I feel and that she feels very fortunate that I make her feel capable of enjoying her sexuality. Months ago we used a dildo, she would suck my penis for a good while and then decide to suck the dildo while I was penetrating her, it was so exciting to see her so focused sucking while I was penetrating her, that I couldn't hold back much and came in bursts. It's been two weeks since we've had sex like this because of visitors, the last time was a few days ago when we snuck into the bathroom but could only have a quickie, now we want to get it on good and tasty. The last fantasies we've had are infidelity ones, where I switch from being the husband to the neighbor, my wife is unfaithful, my husband doesn't please her and as lover I have the biggest cock, that if the husband discovers us he'll either stay watching or join in a threesome, that if as lover I don't satisfy her she'll look for someone else who will, well I think she already knows me pretty well and surely knows that this thing of being a cuck gets my attention. I'm looking for your advice, how should our sex be when the visitors finally leave? What do you guys think?
