Being Her Sub

My wife Claire is a slut. There's no denying it, or in fact satisfying her with just one cock. It simply isn't happening.
We're both in our twenties, yet my wife isn't really into guys my age. I'm only her second sexual partner who's been around her own age. The rest, the other forty plus men who've fucked her, have all been much older than my wife.

Even now as I type this, she's upstairs being fucked by a sixty one year old man. He's a neighbor of ours and ever since we moved in next door to him, he's been fucking Claire.
I obviously knew before we married that my then girlfriend had an insatiable sexual appetite. And even though she at first didn't want to know me, once she knew of my sexual fetish, we got together.
When our neighbor has finished fucking my wife, she'll shout for me to join her. And then I'll get to indulge in the fetish I adore. And that's tonguing out my wifes pussy and asshole of cum, making sure I swallow every last drop.

It's a fetish born from inc**t that my mother taught me to hide her indiscretions cheating on my father.
Our neighbor is one of three men who regularly visit our home to fuck Claire. The other two, both in their fifties, don't mind me watching them fuck my wife. And one even has me lick and suck his cock clean after he's fucked Claire.
Our neighbor prefers to fuck her alone, which I don't mind as we've set up a camera so I can watch after he's gone.

Claire has recently asked me if I'd let the guy, whose cock l clean after they've fucked, fuck me, so she can watch.
I'm not sure I'd be into a guy fucking me. Mainly because I reckon it'd hurt. But with a beautiful horny wife like Claire, it's difficult to deny her anything sexual.
