I'd love it if my wife would do it for me, she's done it a few times but didn't like it, so I should say if she'd do it and like it. I'd also love to get a big kiss from her right after her boyfriend cummed in her mouth (if she had one).
On a couple of occasions I have limited the cuck to sloppy seconds and no intimate kissing except for snowballs as a gradual descent into complete denial.
