Prostate Exam

>You're sitting, waiting in an examination room, at little nervous about the exact examination you're about to receive
>The general check-up went well enough, though you weren't sure what you thought about the nurse who completed it
>She's large, taller than even you, with a noticeable rack under her uniform, but she was very friendly and polite through the whole thing
>Now though it turns out you're due for a prostate exam and while you're no stranger to having things put up your butt, the horror stories told by others don't exactly put you at ease
>The nurse seems understanding and seems to be trying to let you feel at ease before proceeding; after calming your nerves you let her know you're ready
>"Well if you think you're ready, you can turn around and rest your arms on the examination table there after moving your pants and underwear down enough for easy access."
>Complying with her gentle orders, you get on your feet and turn around; hesitating for a moment before sliding your clothing out of the way, revealing your bare ass (and your package in the front), but little else
>The nurse moves up behind you, close enough that you can tell right where she is, but not too close to make you feel threatened by her size
>Little does she know (or perhaps she does and isn't showing?) that her friendly but still authoritative demeanor, coupled with her size advantage over you, is actually quite calming in this situation
>You hear her put on one, two, three? (no, it couldn't have been three, she must have been adjusting on) gloves on, then the sound of lube being applied to her finger
>"Okay, now relax. This shouldn't be uncomfortable so long as you don't tense up."
>You do as she says, trying to relax as you feel one of her gloved digits gently press at your asshole
>The cool sensation of the glove and lubrication causes you to tighten up, making her ask you to relax again
>You manage to relax enough again for her to slip the finger in with a slight bit of pressure

>You have to admit, with the warmth of her finger heating up the glove now and the moisture of the lube, it doesn't feel too bad
>She slowly pushes the finger deeper in, starting to brush against your inner wall, looking for your prostate
>When she finds it, the finger begins to inspect it gently, which feels an awful lot like she's massaging the sex organ
>This stimulation causes your dick to twitch in pleasure and your crotch to warm with arousal, despite not getting an erection
>She must have noticed because she speaks again while her finger continues to probe your rear, her voice sounding more amused now
>"Have you experimented with your ass before Anon? You seem a bit more welcoming back here than most others..."
>You meekly nod and reply in a quiet voice that, Yes, you have experiment back there several times before
>"Good, prostate stimulation is good for your health, which is probably why you seem just fine back here."
>She pulls out her finger (but not before giving your prostate a firm press), but doesn't move away or ask you to stand up
>"Now, you appear to be nice and healthy; but I can give you one last 'treatment' to make sure you leave... content and relieved. Would you like that?"
>She moves in close and leans down over you, letting you feel her bust brush against your back and her... is that...?
>It's now you realize that she did apply three coverings, but one of them wasn't over a hand, as her sizable cock, wrapped up in a condom, sandwiches itself between your cheeks
>Understanding now what she meant by "treatment" you take a couple of moments to realize that you do kind of want it before nodding slowly in consent

>"Gooood~ Now just relax again and I'll make sure you get a nice, happy releeease~"
>She leans back up straight and you hear her taking off her gloves (her condom remains the sole layer between her dick and your ass) before she applies some more lubricate to her cock
>You then feel her hands grab both asscheeks and pull them apart, her now bare thumbs position to either side of your back hole
>Feeling truly exposed to her now, you can't help but blush with embarrassed lust as the tip of her pointed dick rubs against your ass
>"Now before I can start I need to make sure that you are consenting to this therapy. Do you consent Anon?"
>You nod again, a little faster this time, feeling a bit impatient and your lust for a cock in your ass building
>"Verbally please, I can't use just body language for confirmation."
>You quietly vocalize your consent, still a bit too embarrassed to clearly talk just yet
>"I'm sorry, could you repeat yourself louder this time?"
>"I consent to you fucking my ass with your thick cock!"
>Your sudden passionate yell of affirmation (and lust) causes you both to freeze in surprise, even her dick staying still for a moment before she chuckles and begins to press in
>"I think that's sufficient to cover consent. Now just let me help you get that release I'm sure you're looking forward to~"
>The canine cock slips in rather easily after the lube and fingering and you surprise yourself again with a sigh of pleasure as your hole is stretched around the nurse
>You can't help but compare this new intruder to the one not a minute ago, the warmer and thicker cock feeling much more comfortable as it quickly reaches your prostate
>The tip presses against your prostate and continues going, the thick cock putting a wonderful pressure on your organ, making the penetration all the more enjoyable

>And enjoyable is definitely what it is, your own crotch feeling wonderful despite not even being erect, simply twitching and leaking pre-cum onto the table you're bent over
>She begins to pump in and out of your hole, the shape of her dick making for easy but still pleasurable penetration; even with this pleasure though, you still wish she'd attend to your aching need up front
>As though sensing your thoughts, the nurse moves a hand off your hips and reaches around to stroke your cock; the internal and external stimulation having your private at attention in record time
>"I hope you don't mind a little... massaging Anon. I find it helps make this whole treatment much more enjoyable for the patient."
>Your panting will have to serve as an answer, because it's all you can respond with while the canine nurse gently dominates you; her size in both body and dick helping you to feel comfortable under her
>The dual sensations of being on the receiving end of a hand job and ass fucking quickly brings you to the brink of orgasm, making you whine in needy pleasure, alerting the dog-woman of how close you are
>"Just let it out when you want to Anon. Just let it aaalllll out. It's why I'm doing this for you after all~"
>You take her advice and let go, your cock twitching in climax as you shoot your cum across the table under you as the nurse strokes you off to make sure you properly empty your balls
>With your ass clenching around her dick, the nurse seems to approach her own orgasm, moving her arms around your chest and pulling you back into her body, the movement making moan while you still ride out your sexual high
>It's then that you become fully aware of the growing knot that has been pushing up against your back door and just how much it seems like your nurse is intent on securing it inside you
>"I hope you don't mind Anon if I help myself off. Your ass feels so healthy and good and tight and I just want to knot it like the bitch you are!~"

>It seems that her arousal has finally cracked the nurse's professional attitude, her gentleness falling away as she roughly forces the thick bulb of flesh past the final resistance and into your ass
>You didn't think it was possible, but feeling her final knot you- claim you- causes you to have a mini-orgasm, your cock throbbing in pleasure and ejaculating the last little bit of cum out
>The nurse doesn't notice as she holds you close against her, making several more limited thrusts right on through the moment you begin to feel the condom expand with liquid pressure within you
>The two of you stand there trembling in orgasm, you coming down from yours as the nurse rides her own out, the bubble inside you growing by the second with the dog-herm's expression of her appreciation
>When the two of you finally come down from climax, the nurse seems to regain her composure but seems a bit flustered at having lost control by the end though
>"Excuse me Anon. I didn't mean to treat you and speak to you in such a way. I must have gotten caught up in the moment..."
>You tell her it's no problem and that you enjoyed her... passionate handling of your health; though you might need to stay like this until she unties with you
>She chuckles and slowly the two of you begin to affectionately cuddle there in the examination room, your experience having drawn you together in more than just the physical sense
>While cuddling you mention that despite her skilled treatment of your body, you think you might need to come back for more sessions like these; to ensure you're properly treated, of course
>"Oh of course Anon. Constant examinations are the best for your health... and mine. I'll make sure to set you up with another appointment during next week. How does Wednesday sound?"
