Amy's asshole is your urinal

Amy is nervous about what you want to do to her today.

"Please, Elliot," she says, the concern etched into her face. "You know I don't like anal."

You nod sympathetically and you give her a caring smile.

"I know, sweetie. But I told you from the start I would be pissing in your ass."

Her face contorts more. "Yes, you did. I just didn't think that meant...well...fucking me in the ass, too."

Stroking her hair softly, you bring your face close, kiss her on the cheek and whisper, "I'll be gentle." Really, though, you are imagining your cock pounding Amy's asshole into a gaping cavernous pit for you to flood with gallons of your hot urine. Gentle is the last thing you want to be.

Amy sighs heavily, but she slowly begins to strip. As she removes her jeans and panties, you tell her that she should start wearing skirts and thongs to give you easier access to her body. She nods slowly as she presents her nakedness to you.

You run your hands lovingly over her smooth form, turning her around and caressing her ass. When you gently tug her butt cheeks open, she gives a little whimper.

"You have a very pretty asshole, Amy," you say. It's true, her anus is pink and delicate and very sexy. The thought of turning it into your gaping pisshole is thrilling.

Taking her by the hand, you lead her into the bathroom. "No need to get the bed messy, hmm?" you say with a knowing smile. She steps into the bathtub and, following your directions, kneels down with her ass in the air, hands reaching back to spread her cheeks wide, her head on an inflatable bath pillow that you have thoughtfully provided. You pause to admire how sexy she looks. Then you squirt lube onto your fingers, rub it to get it warm, and press a sticky finger against her exposed anus.

"Oh, God," she moans as your fingertip pushes inside, and you can feel her sphincter tightening.

"Relax, Amy," you say in a soothing voice. "I'm going to open your ass very wide, and this will be much more pleasant for you if you can relax back here."

She whimpers as you corkscrew your finger inside her butt. The hot, tight grip of her anal canal is incredibly exciting. You slide your finger out, squirt more lube on Amy's asshole, and work two fingers up her. Her whines grow louder, and louder still when you push a third digit inside. She is mewling and drooling as your three fingers slip and slide in her lubed butt, wriggling around and opening her more and more.

"Time for my cock," you say happily, and she looks up then, over her shoulder, her face twisted in alarm.

"Please...please be so gentle," she beseeches you, eyes wide and pleading. She watches as you undress, your cock rock hard and jutting upwards. You smear lube on your head, climb into the tub, kneel behind her, and rub yourself against her delicate asshole.

"Remember, Amy, relax," you say to her sweetly. "I want this to feel good for you." This is not really true, but you figure it's what you should say. And then you hold her hips and begin to sodomize your whimpering girlfriend.

Oh, how glorious it feels as you slide gradually inside. The iron grip of her asshole, so satisfyingly tighter than her cunt, keeps your cock hard as a rock as you push further. You reach under her, in a moment of charity, to rub her clit, and the music of her mewling goes up a key. You rub her and you keep your cock moving forward, like a shark. Only when your balls smack her ass and you are fully buried in Amy's rectum do you pause, savoring the feeling of being completely inside your sweet girlfriend's ass.

Then you begin to fuck her in earnest. You slide back and forth in the aching ecstasy of Amy's asshole, savoring the tightness, the heat, her beleaguered cries. Abandoning her clitoris, you grip her ass cheeks firmly and thrust in and out. She reaches under herself, taking up the task of rubbing herself, gleaning some pleasure during this anal ****.

After several minutes of this, you pull yourself all the way out and closely observe her sexy asshole. It is opened and dark pink inside and you cannot wait to flood it with your hot piss. You push back in as she cries out and you fuck her a little harder, your balls making a slap-slap-slap sound against her firm butt cheeks.

"Oh, fuck, Amy," you grunt, "I am going to cum so hard up your ass. And then I'm going to piss deep inside you."

She moans, and you can see her hand moving quickly under her, rubbing herself. You wonder if she can cum while you assfuck her.

"Do it!" she cries. "Fuck my ass, cum in it, piss in it! Oh, baby. I am your urinal, your nasty girl. I'll do anything, whatever it takes, to prove my love!"

Even though she's been showing you how nasty she's willing to let you get for a while now, her dirty words still make your heart race. You can't believe that sweet, demure Amy has become such a filth pig for you.

You fuck her harder still and she moans and screams and rubs her clit and urges you on. "Fuck me in my ass! Oh god, I'm your little whore. Your piss whore butt slut! Fuck me, piss in me, **** me, Elliot!"

Tightly holding her hips, pounding her ass, cock sliding in and out in her anal canal, you are grunting like an animal, spit falling out of your mouth onto her back.

"Yessss," she cries. "Do it, cum in me! Cum up my ass, then piss in my ass. Oh baby, make me drink all that nasty mess out of me!"

That does it. Holding her tighter, you slam into her and spray stream after stream of hot gooey sperm deep into her bowels. She howls with you, her fingers pressing down hard on her clit, and her bucking movements indicate her own orgasm. Together you cum, pressed together like animals in the bathtub.

You lean over so that your mouth is at her ear. Your cock, softening, is still buried inside her.

"I thought you hated anal," you whisper, and bite her earlobe playfully.

"It hurt but ... it also felt sexy as hell," she admits breathily. "I came so hard."

You kiss her ear and her cheek and your mouth finds hers. She kisses you back, then looks into your eyes, and whispers, "Do it, Elliot. Piss in my asshole."

Staring back at her, you say, "Yes. And then I am going to make you drink that nasty mess out of your sexy butt," and she shivers, with disgust or lust, you're not sure.

Pressed against her ass and holding her tight, kissing her, you empty your bladder inside of her. You feel your urine coursing out of you, flowing into her, and the filthy nature of what you're doing is beyond exciting. Amy sighs, her mouth twisting in a grimace.

"Oh, fuck, Elliot, it burns. Your piss is burning my poor little ass. Oh, God, it's so fucking hot!"

You hold her tight and piss deeply in Amy and feel surprisingly emotional towards her. Could you in fact be in love with her, rather than simply be using her as your degradation toy? The thought is honestly perplexing.

When you are finished, you pull yourself out carefully. Amy squeezes her ass muscles to keep your piss in, a movement that causes her to cry out, her butt being incredibly tender. "It burns, oh God, it burns," is all she says.

"Be right back," you say and you leave the bathroom, returning a moment later with a long stem wine glass. As you watch intently, Amy squats over it, facing away so you so can watch her asshole pulsate as she squeezes out the mix of cum and piss into the glass. Her ass is deliciously open, red and raw, and as the mess flows from it, you know you will be getting her to do this again. Soon.

Amy turns back to face you, eyes a little glassy, and raises the glass as though making a toast.

"Here's to being a filthy, fucked up whore for you," she says solemnly, and gives you a little wink.

Then she takes a large gulp of the piss-cum mixture, swishing it around her mouth as though she were wine tasting, and swallows it down with a loud, satisfied, "Ah!"

"Yummy?" you ask.

"Disgusting!" she declares. Then she swallows the rest in one big gulp.
