The short version, only the consensual variation for those who don't want to see the rough stuff.
The start is on a Weekend morning with me waking up around 9 AM in response to unhappy noises from the dog crate. I sigh and get up, taking a leak before sending Vixen out to do her thing. After re-crating the dog I'm hungry, so it's time to nuke a breakfast sandwich and eat it in front of the big TV.
As usual, I watch a show recorded during the week on the DVR. The show I watch is an episode of HBO's "Real Sex." I finish the sandwich during a segment on spanking, with a "teacher" giving a paid class to clueless yuppies titled "Spanking 101." The second segment is another class, on the joys of anal sex.
As the ass-fucking segment ends the pager from the bedroom begins beeping. I turn off the TV and head back to the bedroom with the remote control in hand.
In the bedroom I find Mary sitting up on the edge of the bed and I greet her with "I've peed, the dog has peed, I guess it's your turn." Still groggy, Mary nods. I move past Mary and sit on the corner of the bed, giving her room to get the toilet in position, transfer on to it, and splash out a large pee.
When Mary was finished I grabbed a wet nap, wiped her from the front, and then did the back after she stood up and bent over. After the final wipe I tossed the used cloth towards the trash and gave her ass a swat. Mary twitched and said "Thank you sir, may I have another?"
I slapped Mary's left butt-cheek pretty hard, getting a nice loud sound. Mary shivered and said "More please" in a soft, sighing voice. I grabbed her ass firmly with my right hand and shook the soft, heavy cheek, telling her "Not in this position, lie down now." Mary turned to sit on the bed and then lay down in her usual position on her back. I did not say anything, just reached down to push on her hip and shoulder until she figured it out and rolled away from me. Mary settled face down in the middle of the bed, and I went around to my side of the bed to join her.
I pulled the "adult toy" drawer out of the nightstand and got onto the bed, kneeling on the bed at Mary's ass. I started by fondling her buttocks, stroking the pale skin and gently kneading the soft masses. I gradually increased the strength of my grip, and after five minutes I was digging my fingers deep into fat and muscles, the tips of my fingers hitting bone. Mary was squirming a bit and sighing softly each time I clenched a hand tightly.
I moved my left hand to hold Mary down by the small of her back, and spanked her the center of her left buttock with my right hand. The blow made a loud sound, and Mary twitched and gasped. I watched as a light pink handprint developed on the pale skin, then quickly delivered another 4 strokes to the same spot, followed by 5 more to the same location on the other cheek. By the time the ten spanks were delivered Mary was yelping and wriggling, her legs kicking. She calmed down as I briskly rubbed my palm across both impact areas before returning to just stroking and kneading her ass. With Mary relaxing I used my left hand to grab and open the bottle of warming oil so that I could pour a thin trickle in front of my moving right hand.
I kept adding oil until my hand and both Mary's ass cheeks were shiny slick, then poured a line up Mary's ass-crack, following the oil with my fingertips. I kept rubbing both cheeks, working my fingertips steadily further into the warm groove between them each time my hand moved up or down vertically. After a few minutes of the slippery ass massage my fingers were bumping gently across the tight knot of Mary's anus, and slipping a little between her outer cunt lips on each stroke.
Mary was getting excited. As my fingers went deeper between her furred lips I could feel the moist heat of her arousal, her juices thinner and more slippery than the oil. I eventually slid deep enough for my fingers to bump across her clit, drawing a gasp and shudder. Mary spread her legs to encourage the stimulation, so I concentrated for a minute on gently stroking her clit with the fingertips of my right hand. I continued squeezing and probing her right buttock with my left hand. In a couple of minutes I had Mary shivering and moaning in pleasure, trying to hunch her ass back against my fingers. I stopped moving my right hand, just holding my index fingertip against her clit as I began spanking with my left hand, at first gently spanking the cheek I had been groping.
At first I was just patting Mary's right buttock, and she was more concerned with trying to hump her clit against my unmoving fingers. I steadily increased the force of the blows and reached the point where I was getting a good slapping noise, and Mary was jumping and gasping with each stroke. I folded the two smallest fingers of my right hand and pushed the other two slowly into her cunt while still spanking.
Mary moaned loudly, the muscles of her hot vagina clutching at my fingers. With the fingers fully into Mary's cunt I could feel the hard knot of her cervix at my fingertips as I ground my last two knuckles against her clit. Mary was groaning "Yes, Yes, Yes..." until I gave her 5 very slow slaps on the same area of her buttock, hitting her quite hard. Mary cried out "Ow! Yes!" 5 times as I alternated slaps and clit rubs, then switched to roughly rubbing the hot, reddened skin.
I leant to my right so that I could twist my right hand. Before Mary could complain about the spanking I bent the fingers in her cunt, my probing fingertips rubbing her G-spot. I began quickly stroking the textured area of vaginal lining and Mary came immediately. I spanked her so far unmarked, gyrating left buttock as Mary writhed before me.
I had trouble keeping my two fingers in Mary's spasming cunt as a gush of hot juices leaked out across my hand. Mary's clit was grinding against my knuckles, and her anus was twitching against the ball of my thumb. Mary's inarticulate gasping moans were punctuated by the sharp sounds of the continued spanking and underlaid by the liquid sloshing from the action in her cunt. After a minute Mary's spasming slowed and I stopped spanking her, just gently kneading the red impact areas on both jiggling ass-cheeks. When she gasped "Enough!" I stopped moving my fingers and slowly pulled them out of the sopping wet pocket that clutched at them.
It was my turn. While Mary lay sprawled and panting I moved over her left leg to kneel between her thighs. I lifted the small vibrating egg from the drawer of toys and slipped it gently into her slick cunt. At the other end of the vibrators lead wire I set the control to the slow end of its range and turned it on. I could barely hear the soft humming from inside Mary's vagina, and she did not seem to react to the stimulation at first.
I leaned forward over Mary's ass, putting my hands on the bed near her ribs, and slowly lowered my groin against her. The length of my rigidly erect cock settled against the warm, slick groove between her soft buttocks, and I gasped as my groin pressed against the hot skin of the spanking impact zones. As more of my weight compressed Mary's ass her groove took a soft grip on my cock. My groin throbbed, my lube leaking out to mix with the oil and orgasmic juices already slicking her whole behind.I was very aroused, desperate to get into Mary. I moved back until the purply engorged head of my cock slipped out of her ass-crack and then moved forward, pushing straight in. I felt her groove part for me, and was lucky to have my cock slip straight in until my glans pressed against her anus. I felt the hard knot of her sphincter against my piss-slit and slowly pushed forward against the muscle.
Mary reacted to the touch by weakly pleading "Don't hurt me!"
I assured her "I'll stop if you tell me to." Except for her heavy breathing Mary remained limp and quiet as her asshole slowly opened for me. I penetrated Mary's anus in slow motion as the wrinkled ring of muscle relaxed, feeling the tip of my glans move into the heat of her colon. Mary gasped a few times during the dilation, but otherwise lay still. When Mary's stretching ring reached the diameter of my cock-head the whole head suddenly popped through the restriction. I felt my glan’s corona compress to enter Mary and then flare out inside her colon, locking behind her anus.
I felt Mary's spasming anal sphincter clutching my cock tightly, right behind the glans. Mary's rectum was hot and very tight, the soft lining of her colon cushioning the strong rippling grip of the rings of muscle. Mary shivered under me, her whole body quivering like her anus. I shuddered a bit too, groaning in pleasure.
Mary's anus adapted to the size of my shaft after a minute, the spasming slowing and stopping. I pushed down, driving the length of my cock into Mary's ass. Mary was panting heavily, making small, pleased sounding grunting noises. Mary's colon muscles clutched at me, but not as tightly as her anus, so I felt stimulation, not resistance. Her anus smoothly squeezed its way up my shaft until it reached my tight scrotum and I held still with the full length of my cock jammed up Mary's back passage.
I kept still for a moment, relishing the feelings. As well as the flesh on flesh sensations I could feel the vibrations from the egg in Mary's cunt along the underside of my cock. I was so aroused I would not have believed it possible, but I could feel my already rampant cock swelling larger, Mary's tight sphincter acting as a cock-ring. I was worried about Mary as the growing base of my cock stretched her anus further, but when I started to pull I only got about an inch back she gasped "No, I want it in me!"
I smoothly thrust back into Mary, and she gasped "Yes!" as my groin compressed her butt. We both groaned in pleasure, enjoying the feeling of my cock sliding through her colon. I immediately pulled back again, hauling half my cock out into the cool air and sliding it in again. Mary liked that, pushing her ass up against me as I pushed slowly down. When I hit bottom Mary shuddered and said "More!"
I groped for the vibrator control, pushed it to high speed, slowly pulled most of my cock out of Mary and steadily drove it in again. As it went in Mary pushed her ass up again to meet the thrust. As I pulled out again Mary moaned "Harder damn it, fuck me, fuck my ass!" That did in the last of my self-control. My next thrust was hard and fast, my lower belly slapping against Mary's pliant ass. I sodomized Mary with fast, deep thrusts, fucking her ass with all my strength. My hands gripped her shoulders, keeping her in place to meet each stroke. At first Mary gasped "YES" each time I entered her, but the words blurred as the excitement mounted until the soundtrack was her in-articulate moans and the heavy breathing of both of us. The slapping noises of belly to ass got louder as fucked Mary's ass forcefully, sometimes hearing between the noisy breathing the obscene, liquid squelching sound of the penetration.
We both got very excited quickly, the rapid ass-fucking winding us up. Mary's noises rapidly went up in pitch, her whole ass twitching as she shuddered into her orgasm. The pressure in my groin peaked and as the first throb of my release started Mary cried out in pleasure, her anus clamping down tightly as she came. My cum backed up painfully for a moment before the tight grip eased. I yelled also as a huge wad of jism surged up my cock to squirt deep into Mary's digestive tract. I humped my hips, seating my cock more firmly into Mary's shaking ass as my throbbing ball pumped wad after wad of slippery cum into her colon. I could feel the goo spreading around my cock as the rippling grip of Mary's colon sucked me dry.
Both our orgasms subsided together leaving us limp and gasping for air. I slumped on Mary's back, then slid off her to the left on a slick film of sweat, oil, and bodily fluids. I shivered as I felt my rapidly shrinking cock slip out of Mary's ass. Despite the exhaustion, I had to look. I hauled myself to where I could look over Mary's thigh and reached out to part her cheeks.
Between Mary's spanked-pink buttocks her dilated anus gaped bright red, still almost an inch open. It was well stretched, but did not look seriously damaged. I watched for several minutes as the dilated ring recovered, the hole shrinking down with a slow leak of gooey cum trickling out.
