Using Her Backdoor

Carmen was still rubbing her clit as she leaned back on the toilet reservoir. I pulled the lever to flush her dispelled ass water away and told her "Be right back." as I headed out the bathroom door towards the kitchen. After some rummaging around through the utensil drawers I located a large syringe normally used for injecting liquid seasonings into meat. In the cabinets I spied a freshly opened bottle of Wesson cooking oil and drew the syringe full of the slick liquid. When I returned to the bathroom Carmen was already back in the tub again with two of her fingers pumping at her swollen pussy. I told her to assume her earlier position and she did as requested pulling her as cheeks wide for me. I announced "Dr. Sean has a little injection for you. You might feel a small amount of discomfort but only for a short moment. This'll make you feel all better. Now open wide and say 'Ah' for me" I instructed as I held the syringe up for her to see, making it accidently squirt a little oil on her now flattened tummy.

She was still giggling as I gently inserted the syringe into her asshole and slowly began the oil injection. She asked, "Doctor, are you sure this is a normal procedure?" I deeply cleared my throat and in my most professional manner assured her, "Yes, Miss Tight-hole this is a most common treatment for someone with a condition such as the one you currently suffer from." As the injection continued her rectum would spit and sputter for air occasionally but she eventually took the entire contents without complaint. I then began finger fucking her ass with my right hand. A small portion the oil was squirting out, running down into her back, also into her pussy and all over my hand. I worked my way up to four fingers then slipped my thumb in. Carmen's asshole seemed to be stretched to the max as I attempted to push my fist deeper. "That's as far is it'll go Carmen, your asshole simply will not open any wider than that."

"Don't give up so easy you big pussy." she grunted. "Twist your hand back and forth. It'll go in there dammit, I know it will. Come on already Sean, screw it in there for me tough guy." she snapped irritably.

I did as she said and sure enough my hand slipped in past the finger knuckles but the thumb knuckle wasn't gonna happen. After a few moments at that depth I decided to give up so I eased my hand back out of her stretched greasy asshole and told her, "Sorry baby, I did the best I could for ya. I just shoulda been born with a smaller set of hands. Alright trooper, get out of tub and bend over that toilet. I'll ram a hot dick way up in there for ya and I guarantee that'll wipe that frown off your pretty little face. "

Carmen was gazing off into space not paying attention to a damn word I was saying, then she cocked her head and stared at me as if in a deep trance. I started to wonder if she was really gonna be pissed because my big fist wouldn't fit up her tiny asshole. Suddenly she said with her best Texan accent, "Well guess what, I was by-God sure born with some small hands and I'll be go to hell if I'm gonna lay here with my rectum all filled with perfectly ruined cooking oil and call this whole fuggin' adventure a gawd damn failure." She began trying to wipe up some of the oil up from the tub floor with her right hand. " Be a doll and go get me the rest of that bottle of cooking oil, sugar please sweet meat." she said as she began to put her plan into action.

I fetched her the cooking oil and when I got back to the bathroom she was laying flat backed in the middle of the tub with her legs propped against the wall. She rolled her heels back over her head and told me to help her keep them secure. I laid my arm across her calves and that seemed to be all it'd take. Her wet pussy and now slightly gaping asshole were aiming straight at the ceiling. She had me pour cooking oil over her right hand and began finger fucking her asshole with two fingers. She kept getting faster and faster, cooking oil still spilling and spurting from her stretched asshole. I was just about to cum on myself watching this wildly erotic scene.

"Are you just masturbating that asshole or sincerely trying to get that fist shoved in there?" I inquired.
"Both dammit, can't I have one more little orgasm before I get down to the real fucking business. I just love playing like this while you're watching me."
"Sure, but remember I'm still planning on having me a helluva orgasm all up in your real fucking business and I mean like real fucking soon if you follow my drift?"
"Oh shit, I'm sorry, I forgot." Carmen said, now using her innocent little girl routine. "You haven't even got to shoot your load once today have you? Oh damn, how absolutely impolite of me. I oughta have my selfish little ass spanked extra, extra hard - no, no, a far more severe punishment is in order for such an inconsiderate little horny slut like me. Let me think, whatever could we do that would be severe enough? Oh I got it! I believe I oughta have my asshole fist fucked. Yeah, that's it! That's the perfect punishment! My asshole definitely must be fist fucked right away! Make it so master! Let's make it so right now! Maybe you can spank my naughty ass a little while I get it stuffed in there." She let out one of her silly little girl giggles and she had me cracking up.

She began working the third finger into her ass, then the fourth, then the thumb and ultimately bearing down hard for the final intrusion. She hand me refill the syringe from the cooking oil bottle and shoot the greasy fluid directly into her rectum two times as she held her opening stretched wide. I popped the side of her bare ass available to me a few times with my greasy open palm leaving my hand impression temporarily tattooed on her creamy cheek. I could tell she was on the verge of cumming again.

"Ooo, Ooo, Ooo, Ooo" she kept panting in quick gasps. Then unexpectedly it happened with a audible plop and sucking sound, her fist disappeared into her rectum and her sphincter immediately gripped tight around her small wrist. She let out a long , slow, deep voiced "OOHHHH--- God,---I can't---believe---I ate--- the whole---fucking---thing. Un-fucking-believable. And wow, my poor sore pussy just came again for me, can you believe that shit?" As I sit on the edge of the tub I gently stroked her tender hardened nipples and dabbed the sweat from her forehead with her wadded up Bud t-shirt. I soothingly whispered to her how damned pretty she looked right there just like that and how I believed I could sit and admire her in that position from now on. She suddenly turned her face up towards me and sweetly asked me the dirtiest question I believe I've ever been asked "Will you please squirt your hot cum in my face while you watch me with this fist up my spread ass."
"Wye certainly ma'am. I'd absolutely love to." I promptly replied to her in my most southern gentleman tone.

I finally got to pull off my khaki shorts and briefs exposing my throbbing six inch cock. A droplet of pre-cum was already seeping out the pee hole slit. Carmen instantly spotted this and insisted on tasting it. I wiped it off with my finger tip then inserted the finger in her mouth. She sucked my finger in an erotic sensuous motion and then let it plop from her lips. She lustily commented on how my juice had tasted like liquid salt - but in a really yummy good way.

Carmen instructed me on how she wanted me to achieve my orgasm. First having me roll my throbbing meat back and forth between both my open palms over and over. This motion kept forcing additional drops off pre-cum fluid out the tip and Carmen insisted I pause to feed them to her and she hungrily lapped each from my finger tip as she'd done earlier. I then placed my right foot into the tub towards the end where the drain and faucet were located so that I could have an excellent view of Carmen's crotch area. She then had me to stroke my cock with one hand while I caressed my balls with the other. I was almost ready to explode when Carmen said "Watch this!" and she started making her greasy fist slowly appear then disappear back into her rectum. The erotic gooshing, sucking and plopping noises coming from her slickened fist and sloppy oil-filled asshole seemed to be getting louder with each repetition of her extractions and penetrations. Oh wow, this was indeed a real live anal fist fucking that I was getting to witness! I felt as if I needed to pinch myself to make sure it wasn't just a wet dream but I was already touching myself in another way that felt far more satisfying.

She sped up her pace as I stood above her jerking my cock faster and faster. Just a few moments of watching that action and I was ready to shoot my hot cum all over Carmen's face, stomach and crotch. She could tell how close to exploding I was by my moaning, grunting and the steady waves of uncontrollable spasmodic jerks starting to flow through my body. She quickly plopped her fist from her greasy ass and got to her knees as she wrapped her lips around the tip of my cock. I moved my hand away allowing her to swallow my member deep into her throat. She nudged the back of my left thigh with her hand motioning me to place my foot up on the edge of the tub in order to give her clearer access to my crotch. She had no trouble finding my quivering sphincter with two of her oil-slickened fingers, quickly working them into the small opening and driving them in as far as she could up my tight chute forcing all my boiling semen to spurt out my cock deep down into her throat. My sphincter muscles were violently convulsing and were repeatedly slamming shut and relaxing around her two motionless fingers over and over again as I used my right hand to finish milking out the last of the goo from my softening penis letting it drip onto Carmen's eagerly extended wet tongue. She then lovingly kissed and sucked on the head of my tingling cock using her tongue to thoroughly and meticulously get every single trace of my love juice sucked out and mopped away.

My knees were still shaking and weak from my turbulent orgasm and I felt as if my body was balancing solely on Carmen's inserted fingers. She slowly withdrew her supporting digits from my asshole and I slid down into the messy bath tub beside her. Carmen turned the tub water on and we began gently washing each other up. As we bathed each other Carmen whispered in my ear "That has to be the one filthiest act I've ever done in my entire life - bar none!!"

"I tell ya what sweetness, that sure ranks right up there in the top best sex experiences of my whole life - I ain't kidding you one fucking bit. Whew wee, good gosh-a-mighty goddamn gal!! You are the most hottest, sensuous, dick hardening, cum squirting creature I believe I have ever met. God, I don't remember ever cumming so fucking hard! But while we're on the subject and since this keeps eating at me, I'm still really hoping you don't ever feel obligated to describe our private little kinkiness to Libby in even the faintest detail. You know, if you ever feel like ya just gotta tell her something would ya please just clean it up some. Tell her I like to fuck your pussy long and hard normal style - assuming I don't accidently cum too quick - and we maybe occasionally trade out head jobs or some something kinda on those lines - can we call that a deal?"
