Breed her into submission

It's practically what she is asking for. With the **** in both your bloodstreams, any caution and professional demeanour you two might have been capable of go right out the window. "Not what I expected negotiations with someone so prolific to be like." You say, causing her to laugh at the little compliment. "I'm not that big of a name." She replies, "Besides: I like what I see and don't think there's a reason to be coy about it."

She hops off her chair and seems to consider taking this to her bedchamber for a few moments, but after a brief exchange of looks between you two, you come to the shared conclusion that the furs on the floor will be more than enough. There's a split-second in which you consider being cordial, gentle kisses and lovingly passionate foreplay, courting the forgemaster with all the charming restraint an elf of your caliber can muster. But the mere thought of having this plump fertile beauty at your mercy flips a switch in your brain, leaving nothing but instinct and a fiery need inside your loins. Your next move is a swift one. Like black lightning your form slams into hers, wrestling her to the floor with both size and strength. She's caught off-guard at first, but reacts accordingly in a matter of seconds. Grunting and panting like animals in heat you roll across the floor, playfully wrestling each other for dominance. She is strong, terrifyingly so, but as if the book at your hip empowers you, you somehow win out, finding yourself on top of her. Both of you sweating and in dire need to gather your breath, you share an almost loving look of passion before your lips meet hers. Again you delve into a power struggle, your tongue pinning her down and dominating her mouth in muffled moans. Jolts of pleasure rush through your veins, blood pumping between your legs.

She gasps a little in surprise when she feels that massive bulge pushing against her midsection. Even with all that fabric still covering you two, she can feel just how mighty your kind really is in this department. The tales of sexual deviants and mass-breeding slavers from dark elven lands are exaggerated, but have a considerable core of truth to them.
You let your fingers roam, tracing the curvature of her body and stopping at the mounds of her breasts, broad nipples poking out from under the fabric of her apron. You close your grip, coaxing a moan from her as you start fondling her breasts like supple dough, all the while grinding yourself against her, working up a sexual appetite you haven't felt since your formative years.

"Come on." She whispers, her breath torn between moans, "Stop playing around. Fuck me already!"

No need to tell you twice.
The apron is off in a split-second, torn at the seams by how fast you rip it off her. You don't go quite as rough on the other pieces of clothing, but your eagerness shows nonetheless. You marvel at the beauty of her body, practically built for a breeding by a race as virile as yours. Her curves jiggle in rhythmic ways whenever you shake her, the soft flesh of her tits bared to the world now. You let your hands roam a little more, stroking over the bronze tuft of hair above her pussy, her lips already swollen and dripping with need.

Not wanting to keep the fine lady waiting any longer, you remove your own clothes, the light of the chamber reflecting off of your black skin like sunlight off gemstones. Your physique is chiseled for an elf, brimming with defined muscle in the manner god-revering statues are built. When you tear yourself free from your underwear, your cock springs free, the black meat slapping on Tagaera's stomach with a wet thud. Once more a gasp escapes her. Idly she hold up her hand to compare sizes between her limb and your length.
Your cock is a perfect mast of shining black, covered in rhythmically pulsing heavy veins, as long as your forearm, and just as thick. Below hangs a smooth-shaven sack, your balls heavy and swollen with cum, larger than the most bountiful fruits of your homeland.

You are massive. Even for one of your kind, and she knows it.
"Fffuuuck. Are all dark elves this big?" She asks in complete denial of the size that's about to break her in. Lying on her like this, you can tell that if you wanna go all the way, you're gonna stuff her like a doll.

"Maybe you just got lucky and stumbled into an extra fine specimen." You say. Before she has a chance to retort anything else, you line your length up with her eager dwarven pussy, spreading her lips in a broad O-shape around your blunt tip. You'd expected her to be one for a rougher hand in bed and you're proven right almost immediately. She moans out in a mixture of discomfort and pleasure, bucking her hips into your first thrust. No lube needed when she is so wet she could cum you a river. You press your weight down on her and roll your hips against hers, working inch after inch of black elf-meat into her cunt, stretching her out and causing the pitch of her moans to rise higher and higher.
It is only when you encounter resistance, that your advance briefly stops. You can feel that plush inner ring stopping your massive length in its tracks, her cervix not used to something this massive knocking at her inner gate. The breath is pushed right from her lungs as you buck your hips again and again, stretching out her insides more and more. "So deep...Fuck, you're so big." Is all she can manage to say, barely able to give you anything coherent as you attempt to work your final inches into her.

Your cock is outlined under her stomach, causing a noticable dickshaped bulge to form in her belly with every renewed thrust. You grunt and growl like a beast possessed, the occasional. "Take it...take it all!" Escaping you as the resilient defenses of her body cause your ambition to overwhelm your reason. You pull back, almost to the tip...and slam yourself home. Over and over again you repeat this with slow deep thrusts, the clap of flesh against flesh leaving red marks on her skin as you slam that battering ram of yours deeper and deeper.
Her eyes roll back until only white remains, her hands grasp at anything they can get a hold of and her legs begin to tremble and twitch as you break into her womb. You both howl in pleasure at how tight her fertile body is gripping you. You hilt yourself inside, hitting the back of her innermost flesh, your fat balls resting on her asscheeks, pulsing in growing need.

You give her a few brief moments to adjust herself to the massive size impaling her like a living cocksleeve, before you wrap your arm around her, and settle into a frenzied rhythm. The conqueror inside of you will not take anything but total victory here. You will make this dwarven mistress your breeding bitch and if it takes every last drop of your cum to do so. Perhaps the book is already influencing you both...your own mind asserting itself over hers. You can feel her spasm in orgasmic bliss already just at you putting that thought into action. For all her strength and pride? She wants this, you just know it, she needs your seed, your satisfaction spilling inside her over and over again until she can no longer think straight...
...And you're here to deliver. Forcing anover kiss onto her, you hold her in place with all your might, slamming your entire bodyweight into every thrust and rearranging her guts with your girth. You can feel yourself throbbing harder and harder, your length swelling in a final **** burst of energy. You roar into her lips like a demon as the tingling sensation of release rushes over you. You see stars and your ears start ringing as her body milks you for all its worth. The first heavy rope of cum is dumped right against her ovaries, drowning her eggs in your hot potent cum, then another and another. More and more you pump into her until her belly rounds out, her womb swelling with your copious loads. The thought of her knocked up with your offspring causes you to throw yourself deep into another thrust with every new shot blasting her insides, **** to knock her up completely and without escape. This isn't even about the deal anymore. It's all just primal and perfect. A dark elven menace putting a dwarven maiden into her rightful place - As a cockdrunk fucksleeve at your mercy.

That thought was certainly not entirely your own. You *know* the book is influencing you in this moment...but you kinda like it. You are not only still hard and needy, no you seem reinvigorated even, your balls somehow feeling just as full and heavy as before.
While the quivering slutty mess below you cums her brains out with every spurt of superior dark elf seed being pumped inside of her, you think of what the deal entailed. You surely had to give her everything you could, just to be safe, right?
