The elf cleric didn't expect that joining an adventuring party would be such a pain in the ass
It should have been obvious that something was awry when the witch was the one who convinced the others to let him join
Mages and clerics didn't exactly get along
At first he thought she was interested in his endowment
Despite suppressive incantations, it was still evident he was packing something beneath his robe
He could only devote so much focus to remaining chaste, lest his party be put into danger
Thus it was inevitable that the witch would eventually seduce him
Only it turned out she too had been packing
He'd been so focused on keeping his own penis under control, he never expected it would be someone else's that would cause an issue
And an issue it did cause
She held nothing back
At that moment it becoming evident why she needed a cleric
She relied on his healing incantations to keep him in one piece
The side-effect being that his insides were permanently stretched to fit her cock
Though, this ended up benefiting him as she managed to seduce him again and again...
With the dungeon cleared, he could finally relax
He may have been trained to vanquish the undead but that didn't make it any less stressful
After ensuring everyone was okay, he was confronted by the witch
The look in her eye told him what she was thinking
Here? In the middle of the dungeon?
Before he could protest she brought her lips to his ear and whispered: "Your focus is waning. It's starting to show"
Glancing downwards, he saw the distinct bulge of his cock
He'd been the one to get aroused, not her
She continued: "How about we go deal with that before someone else see?"
He had no other choice
She made a show of asking him for assistance before taking him into a side passage
There she cast a spell to stop any sound echoing back to their party
Another spell and her clothes vanished
Shamefully, his cock throbbed at the sight of her
His shame only deepened by the fact she was still completely flaccid
There was no denying that his body had initiated this
"How about getting me hard?" She said, holding her limp cock
The thought of it made him blush
Despite her using his ass regularly, he'd never serviced her
Part of him still clung to the idea that this was all her seduction, but that illusion was fading
Still, he resisted
He simply presented his ass, waiting for her to do the work
She squat behind him, groping his ass
Then, as if out of spite, she tore his pants away
She had surprising strength for a witch
"My, your ass is practically salivating"
Her handywork had perminantly deformed his hole into a vertical slit
Another side effect: his anal glands drooled constantly
She huffed the musk deeply before running her tongue along his anus
Slurping and sucking his hole, his own cock quickly grew hard
He found himself wishing she'd get aroused faster as he watched her cock gradually swell
This teasing wasn't going to make him cum
The shame at wanting to be fucked so bad was buried by the relief at seeing her cock reach full erection
Yet, he still couldn't bring himself to beg for it
Instead, he arched his back and pushed his hips into her
"Getting impatient, are we?"
She sighed, "and I was just beginning to enjoy myself"
Standing, she let her cock rub against his as she rose
It was unbelievably big, almost as thick as his thigh and longer than his forearm, yet she had no problem getting erect
Her cock rested heavy on his ass
He looked over his shoulder, glancing between it and her, wondering what was taking so long
As if in response, she said: "I've never seen you this horny before. I'm just enjoying the sight."
Slowly, she drew it back, sliding along his anus until the tip reached the opening
It met little resistance from his loose hole, the head sinking halfway
His anus clung tight around it in excitement
He was already leaking precum
At any moment he could-
CLAP
Without warning, she had thrust inside
He bit his tongue to stop himself from screaming with pleasure
She only fucked him harder, so hard he had to brace against the floor as she lifted him
While he managed to stop himself from screaming, he couldn't stop himself from cumming
Long white streaks shot across the floor as his dick swung back and forth with each pound

He was in no position to deny it
But was it an addiction? or was this dependence?
He had never cum this hard by himself, and he may never want to cum again without her cock inside him
Fortunately, the numbing of his mind drowned out the thought
His orgasm never seemed to end
Each time her cock stirred his guts, churning his prostate, a new wave of pleasure gripped him
He couldn't hold back his moans, even if he had the will to try
Yet his screams were barely audible above the wet, echoing plaps
Had she not cum when she did, he might have lost his mind entirely
As she only stopped to pump her cum inside him
He managed to catch his breath
Sensation was returning to him, the warmth spreading inside him and the cool stone beneath him
At some point he'd fallen flat on his face, the witch fucking him against the floor
She dropped him, letting he cock slide out of his ass
Cum squirted from him as his body gave a final orgasmic convulsion
As much as he'd like to lay there, let the fatigue drag him into sleep, he couldn't
Their party may come looking if they were gone too long
He had to clean himself
Yet he was unable to regain his composure, making an incantation impossible
"Allow me." The witch cast a spell
Suddenly he was clean and dressed, but...
He could still feel her cum inside him, and something large plugged his anus
As he got to his feet the shape of the plug was more evident
Huge, not quite big enough to be seen but could certainly be felt when he pressed his abdomen
"Come now, we don't want to keep our companions waiting"
Her smile as wicked as ever
