We chat after the others leave

After we've finished fucking, and Dan and Gina leave, my wife turns to me, still naked.
"Fuck, that sure was fun... and you certainly seemed to enjoy me fucking Dan, didn't you?"
"No.." I say, a bit unsure of myself now that Melanie is asking about it.
"Oh, come on! You loved it. You don't normally cum that hard!" she fires back in response.
"Ok... so it was kind of hot I guess", I admit.
"Kind of? It was more than kind of... and I loved it too... You know... I might do it again... or...", Melanie drifts off and smiles.
"Or what?" I ask, somewhat concerned.
"Or would you prefer I fuck someone else next?" Melanie asks, her grin growing. "I've heard lots of guys actually like their wife to fuck other men... It's called hotwifing."
"What, are you serious? I can't let you do that!"
"Really? Your cock seems to think differently you know", Melanie retorts as her gaze drops down.
"Umm... sure... but..." I stammer, unable to hide how hard my cock has got again at the suggestion.

Melanie drops to her knees and takes my hard cock into her mouth and begins sucking on me and rubbing my balls.
Every minute or so she stops to ask "you want me to do it don't you?"
"No... I..." I stammer a few times before she's sucking my cock again.
"Come on... admit it..." she keeps insisting.
