I do, baby.

"Yes baby, I think I do" I admit, surprising myself. Somehow the thought of this random guy having cum in Melanie is a real turn on and I want to see.
"Okay, close your eyes and I'll get undressed..."
I do as I'm told and hear the sound of my wife's pants sliding down her silky smooth thighs. Her top rustles as she lifts it over her head and I hear it drop to the floor.
"Kneel down, baby" my wife instructs, and then rests her feet over my shoulders.
"Okay, open your eyes..."
I do as I'm told and the site before me is extraordinary. Melanie's pussy is right before me, red and swollen. It's clearly had some pretty intense action, and as I watch she spreads her pussy lips apart before me. A hint of white is visible at her entrance and she pulls me in close with her feet. The aroma is intoxicating. There's the familiar scent of her horny little cunt, and then there's something over the top of it... the smell of his cum.
"He really used me, baby, he fucked me so hard, it was so good... Can you tell?"
"Oh fuck, I can honey, he did didn't he? You're so red and puffy... "
"And... he really came hard... did he fill me up, baby?"
"Oh, I don't know, but I can see some there..."
"Well don't you think you should find out?" Melanie asks, pulling me closer still with her feet, my face mere centimetres away from her used hole.
"Lick it for me, baby, I want you to sooth my pussy for me..."
Without questioning her I do as I'm told as she pulls me the last of the way with her feet.
My tongue reaches out and tastes the mix of her juice and this other guys cum... it's strange... but somehow intoxicating and I find myself licking at her eagerly.
"Oh fuck yes, that's it baby, yesss!... push your tongue in me... get it all... it feels sooo good... fuck..."
"Mmph." I can only muffle in reply as my head is firmly held against her used slit.
"Oh fuck, you're such a little slut for my pussy, aren't you, baby... Oh fuck, taste me... oooohh... I'm gonna'..."
And with that her hips clamped on my head as she bucked around in ecstasy as she came hard. As hard as I'd seen her before.
"Shit, that was so good," she finally said when she stopped shaking.... "I think I'm going to need more of this! You're going to be doing that for me again for sure!"
