Fantasy Story - Using My Head!

PRE-STORY BACKSTORY:  On one of the forums I visit, a thread posted asking bi-curious guys what they fantasize about the most. 

In both my real world bi encounters as an adult I was pretty much the top.  But in my fantasies, and the dirty talk I share with my wife, it is very much the opposite and I'm the bottom.

I have two main fantasy themes that get detail tweaks but the base idea remains. In both, she is there, fully clothed and not participating in a meaningful physical way. Watching, encouraging, even degrading me for what I'm so eagerly engaging in.  Below is a story about one of those themes.

ON WITH THE FANTASY STORY...

We've all already communicated online and met briefly in person.  We're all comfortable and feel safe moving forward.

He's never been with a man before and he's nervous and feeling awkward.  I'm also anxious but my past experiences say it's best to just get things started.  I get him a beverage and beckon him to sit on the couch, she's already relaxing at the other end.  Quietly watching us both.  He takes a steadying drink and then eases down onto the cushion.  I let him take another drink and settle himself a bit but I'm quite eager and slip down to me knees between his legs.  His legs open, partly from instinct, partly from conscious anticipation.

My hands run over his jeans and up his inner thighs.  He's tense but interested.  I rub his crotch and he takes another drink and then looks down at me.  I smile slightly and he returns it.  The anticipation of pleasure slowly pushing apprehension out of the way.

I rub him through his jeans and over his belly for a few moments before deftly popping open the button and bringing his zipper down.  His breathing his shallow, his hand tightens on his beverage, his eyes fixed on his groin.  I lean in kiss all over his bulge.  His cock is growing and shifting within it's constraint.  My teeth gently bite at his shaft and it responds by pushing swelling and pushing outward.  My fingers slip into the waistband of his underwear and tug.

His beautiful plump head bounces out to greet me.  His cock isn't huge but it is bigger than mine in both length and girth.  More importantly, is the wonderfully sculpted head.  It's gorgeous!  The very tip of my tongue flicks out and runs up between the glans and through his slit.  He moans ever so faintly.  He's fully engaged now, too far gone to change his mind.

As I shimmy his clothes down his legs and he lifts to help, my wife takes his beverage from his hand and sets it down.  "You might need your hands for other things," she coos.  "Like this..." she guides his hand to the top of my head.

His cock is standing proud now.  I lean in close and pause for just a moment to take in his musky scent.  Butterflies smash about in my stomach and I pull his thick, purple head full into my warm mouth.  He moans, this time louder.  I hold him in my mouth, my tongue swirling over his head.  I look up and find him staring straight down at me.

My hand slowly strokes him as I suck and lick the tip of his cock.  I keep stroking him and pull his balls into my mouth.  He responds with moans and gasps and his hand presses harder into my head.  He's all mine now.  Completely into it.

"Stop playing boy and suck it." she demands in a low but stern voice.  "Suck that pretty cock."  Her fingers slip out and gently grip his shaft to point it at my face.

And with that, my lips part and I slowly swallow his hardness deep into my mouth until I feel his belly brushing against my mouth.  His cock barely enters my throat, just shy of triggering my gag reflex but I'm hesitant and nervous as my throat quivers.  But it quickly adapts and I realize he's moaning deeply and his fingers are kneading the back of my head.

"That's a good boy." she purrs.  "That's a good little cock slut.  Suck it boy.  He likes it."

Her words fuel us both and his hips grind slightly.  I pull all the way back until his cock pops from my and springs against his belly.  It makes me smile and I lick it from balls to tip.  He groans and again I take him into my warm wet mouth.  The fingers of one hand hold him at the root and keep his meatiness pointed squarely at my eager mouth while my other hand massages his balls and taint.

For a few moments I just lose myself in the experience.  My eyes closed, tasting his flesh, feeling his grithy warmth, his hips grinding as he succumbs to the pleasure.  I eventually look up to find him staring straight down at me.  I softly squeeze and tug at his testicles while holding his gaze.  It sends him over the top and begins to grind and buck in earnest.

His other hand drops down on my head and his hips match the rhythm of my sucking strokes.  

"That's it!  That's it!  Fuck his face!" she encourages in a gritty tone.  "Fuck that slut mouth!"

His breaths are quick and his groans grow louder.  I can taste the sweetness of his precum and his cock seems to pulse one last time.  His hands grip my head tight, his hips freeze, I can sense his ass muscles clenching and his balls draw up tight in my hand.

And then it happens... His hot cum explodes into my throat and I don't even have a chance to think about before reflexively swallowing.  This is a first for me.  I've never had man cum in my mouth.  It's a powerful orgasm and the second and heavier gush is right behind the first.  I struggle not to choke and have to pull my head back until just the head of his cock is in my mouth.  His hands grip my head and his hips buck as another gush coats my mouth.  It's thick and hot.  My eyes water and his seed oozes from the corners of my puffy lips.  His cum fills my mouth as his groans fill the air.

My own cock rages in my pants.

  

Eventually he shivers and jerks his cock from my mouth.  The post-orgasm intensity too much for him to bear.  I swallow hard.  His cum is in my belly.  

Her finger reaches out and scoops up a thick glob of his cum that drips from the corner of my mouth.  She feeds it to me, "You missed some." she purrs in delight.  Her hand strokes my head, "That's a good boy.  That's my good little cock sucker."
