M

She draws a few pumps of lube from a bottle and smears it all over my ass, then down across my cock and balls, coating me thoroughly. Then a few more pumps and she carefully works a finger inside me.

To aid in opening me up, she rubs my cock and balls, alternating, caressing, keeping in concert with her probing finger. It's not long before she's able to insert a second finger and work them to the hilt.

--I'm going to fuck you in the ass now, R----.

Man, what a day.

The strap-on slides in easily, and within a few strokes she's found a rhythm. I am mesmerized watching her. Her lithe body leaning into each stroke, she uses her hands on my ass cheeks both to steady herself and spread me wide. The strokes evolve into a pounding as she works herself into a small frenzy. Sweat forms on her brow and begins to darken her hair, and before long I feel cool little driplets on my back as she punishes my asshole with her whole body.

She finally slows to catch her breath, allowing me to do the same. The cubic foot of space enclosing all of my sexual organs and surrounding tissue is pulsing. I'm also sweating, and that's requiring more work from my hands and feet to stay afloat on the bench.

This little denouement plays out to its natural end and we both take a moment to collect ourselves. I stand and stretch.

--That's really a good workout. My legs are burning.

--Yeah? You should try running up that hill 4 times.

She concedes the point with a laugh, which in turn lowers the volume on the sexual intensity. We both suddenly become aware of our nakedness and vulnerability. But instead of the moment being diminished in any way, it is strengthened when M steps to me and pulls me into a long, deep, tender kiss. Our hot, moist tongues greet each other gently. Time drops away for a few moments, I feel slightly dizzy, and then...she disengages her mouth from mine.

--I'm not done fucking your tight little asshole. Lie on the floor.

The sudden turn in tone and the dirty language...before I hit the floor I'm hard as a rock.

--Bring your legs up.

She takes my ankles and lifts my legs, then pushes them over so my feet hit the floor behind my head. Then, of course, she spreads my legs to gain access to my asshole. I'm plenty lubed up still so she slides in and gets right back to her frenetic thrusting.

She's chosen this position for two reasons. The first is so she can fuck me and stroke my cock simultaneously. The combination is ridiculous. And each time the dildo presses into my prostate and she's rubbing the underside of the tip of my dick, I moan loudly. She tells me she loves the sounds, and won't stop making me make it.

Before long I feel the re-stirring of the mighty orgasm she'd cut off earlier. I tell her as much.

--Oh yeah? All that cum building up here in your balls?

She moves her stroking hand up and caresses my swollen sack. And between the strap on and the ball rub, I could likely squirt.

The second reason I'm in this position is now clear. M pushes the strap-on in as far as it will go and stops. She tucks her knees forward a bit to hold me steady, crouches, then uses both hands to work my shaft and balls...looking down my cock as a rifle taking aim.

--That's right. You're gonna take this huge load on your face.

Her lubed hand works me from base to tip.

--And then I'm going to watch you eat it.

Swirling fingertips on my balls.

--You're SO swollen!

Although she's not thrusting, the small movements of her arms combine with my efforts to steady myself to allow the dildo to massage me inside. All three of these sensory inputs, combined with the vision of my client, naked, strapped, furiously working to see my cum, dominating me with a clever running routine, the delicious taste of her sex...all of it converges here and now, lighting the fuse on what feels to be the biggest orgasm of my life.

--I--I'm going to cum.

--Shoot it, baby. Spurt that load onto your own face.

--Yes, yes, please...

--I won't stop until you're empty. Show me every drop.

--Whatever you want...

--Spurt it. Spurt it. Come on, cum for me!

--Hnnn...hnnnn...

The only way I can describe what happens next...if you've ever seen a movie in which someone shoots a bullet through the fuselage of an airplane and everything gets sucked towards the hole...all of the crackling energies in my body are racing through my balls eager for release. Once I'm past the point of no return, the surge reaches my balls, and they tingle wildly, a sensation intensified by M's expert caressing. Then the build-up to the first spurt grows in my sack, and I'm careful to fight the tickling urge to squeeze it out and instead let the the muscles contract involuntarily. This maximizes the amount of the first squirt, and it is enormous...

My eyes close and I drift on the wave of pleasure peaking between my legs and radiating outward. After a dribble of pre-cum descends onto my throat, the first rope of cum slashes the air, barely hitting my hair and making an audible slap on the floor behind me. The second and third spurts bullseye my face and open mouth.

--Yes, swallow your cum as it shoots into your mouth!

I am eager to obey and swallow. My mouth opens in time for the next shot, and I swallow more.

After that the pulses diminish, though plenty of sperm empties out of me.

The room hums around our panting, sweaty bodies. M holds me firmly with her knees. She works the last of the load out of my deflating cock and gives it a few more tender strokes before using her hands gently to let my legs down.

It takes a few moments for me to realize where I am.

--That was amazing. Thank you.

--You're welcome. But we're not finished.

M steps around and places each foot between my arms and my body, her heels against each armpit.

--First, let's get all of this--

She bends over and uses a finger to smear all the cum on my face into my mouth. Once she's satisfied, she squats.

--Eat my asshole.

I am more than happy to oblige. And as I do, she finds the cum on my chest and feeds me fingerfulls in between licks of her hole, sometimes swirling the cum on her rim, sometimes even pushing it inside her a bit and make me work to get it out. It is such an immense turn-on that, despite having the emptiest balls in the history of human existence, I feel a stirring in my cock.

The post-coital glow is in full effect. The house is silent, except for the distant bubble of the waterfall. Her asshole is smooth and tasty against my swirling tongue. Little moans ride my hot breath against her skin. M coos in soft reply as we hold onto this still place.

Until a car door shuts.

I hesitate.

--Don't stop. It's just my step-daughter.

The front door closes.

--Rosalie?!

--Yeah!

--Come on up! I've got something to show you! Or someone, really!

I push M off me sit up.

--Hang on a sec--

--No, you hang on a second. I'm in charge here. You just do what you're told. And if I want to humiliate you in front of my step-daughter, then you'll take it. Understood?

A hot flush of embarrassment rippled out from my gut. I couldn't deny her power over me, my desire to obey.

--Understood.

Just then her Rosalie sticks her head around the corner. But instead of being shocked or surprised, she gives a knowing smirk.

--Jesus, Mom, first the plumber, then the electrician, now the handyman?

--I know, I just can't help myself.

M smiles saying this.

--Do you want me to clean him off, too?

--Would you mind? I'd like to take a shower.

--No problem. Come on, handyman.

I start to get to my feet. The women, in unison:

--Crawl.

I follow her down the stairs, through the kitchen and living room, and up into the other wing of the house. We enter her bathroom.

--Into the tub.

They may not be related by blood, but she's picked up her step-mother's stern tone. I climb in. The thought of a warm shower after all I've been through...heavenly.

But Rosalie doesn't turn on the water. Instead she steps up on the edge of the tub.

--Don't move an inch.

--Yes, Miss.

--And don't fucking talk to me.

I catch myself before saying Yes, Miss again.

She lifts the front of her skirt and holds it in her teeth. Then she pulls out the front panel of her panties and pushes them aside, reveals the bald glory of her sex.

--Close your eyes.

I close my eyes and wait.
