"Very well. Sit on my lap, sister-in-law."

Egon invited her with a lustful grin, patting his thigh once.

Noella hesitated for only a heartbeat. Her silvery eyes flickered with a mix of nervousness and raw hunger before she turned gracefully.

The black silk of her gown whispered as she showed her back to him, and the high slit parted to expose the full length of her thigh once more. She lowered herself slowly, deliberately, until her soft, rounded ass settled atop his joined thighs, positioned so that the hard shaft of his still-recovering cock nestled snugly against the crack of her ass cheeks.

The thin barrier of her soaked undergarments and his trousers did nothing to hide how perfectly they aligned.

The moment she made contact, a pleased rumble vibrated in Egon’s chest

His arms slid around her waist, strong palms splaying possessively over the gentle curve of her stomavh. He pulled her back until her spine pressed flush against his chest, her dark cascading hair spilling over his shoulder like waterfall.

With every quickened breath she took, her body rose and fell against him. Soft breasts strained against the low neckline of her gown, nipples already peaked and visible through the sheer fabric.

Beneath her ass, his cock throbbed insistently, thick and insistent, as though it had a mind of its own and that mind was singularly focused on breaching the untouched pussy hidden behind the undergarments.

Egon’s lips found the sensitive spot just below her ear, then spoke against her skin,

"Feel that?" He flexed his hips upward in a slow, deliberate roll, dragging the rigid length of himself along the seam of her ass and the damp pussy beneath. Even through layers of cloth the friction was maddening.

"That’s what you’ve been craving since the moment I bound you."

"Ahhhn, yes..." Noella whimpered as her head tipping back onto his shoulder. Her hands clutched at his forearms where they held her, nails digging in.

"Y-yes... brother-in-law..."

He chuckled darkly, the sound vibrating through both their bodies.

Using his grip on her hips, he began to guide her ass in a lazy, rolling rhythm..

Forward and back, forward and back.

He set a torturously slow grind that forced his cock to rub repeatedly along her entrance. The thin silk of her undergarments had grown embarrassingly wet; every pass left a slick trail along his shaft, the fabric clinging transparently to her swollen folds.

"Such a needy little noble hole," he murmured, one hand sliding upward to cup the heavy underside of her breast, thumb circling the stiff peak through the dress.

"Soaking my lap like a bitch in heat. Tell me. Have you ever let anyone touch this virgin cunt before?"

She shook her head frantically, breath coming in shallow pants.

"N-never, only you... only ever you."

"Good answer."

He rewarded her by increasing the pressure. Hips bucking harder now, grinding the thick ridge of his cock directly against her clit with each pass.

The friction was obscene, the wet fabric sliding and catching, teasing without granting entry.

Noella’s thighs trembled violently around his and small, broken moans spilled from her lips with every drag.

"Mmmph, anngh~"

Egon’s control was on the breaking point. His free hand slipped lower, bunching the front of her gown until his fingers could dip beneath the waistband of her ruined underthings.

There, he found her clit. It was swollen, slick, and pulsing.

He pinched it lightly between thumb and forefinger.

"Ahhh." Noella cried out, hips jerking forward on instinct.

"Shh," he soothed mockingly against her neck, teeth grazing the skin. "Not yet. You come when I say."

He kept the rhythm going. Lazy circles of her hips, slow upward thrusts of his own, relentless teasing pressure on her clit. Until she was trembling on the edge, thighs shaking, breath ragged, tears of frustrated need gathering at the corners of her eyes.

Only then did he still her movements, holding her pinned tight against him so she could feel every thick inch throbbing beneath her ass.

"Beg me to take it," he growled. "Beg your brother-in-law to ruin that perfect virgin pussy right here on this desk."

Noella’s voice cracked, desperate and wrecked.

"Please... please, Brother-in-law. Take me. Break me. Fill me until I can’t think of anything but you. I need it. I need you. Please."

He smiled against her throat.

"That’s my good girl."

In one smooth motion he lifted her, spun her to face him, and shoved her back onto the desk.

Her legs fell open instinctively; the gown rode up completely, exposing the drenched black lace clinging to her puffy, unentered pussy.

Egon stood between her thighs, trousers shoved down once more, cock glistening with her arousal and his earlier release.

He hooked a finger into the crotch of her undergarments and tore them aside with a sharp rip.

Noella gasped, feeling momentarily coolness.

But she could fee something extremely hot and throbbing coming closer to her littlse sister.

As expected, he lined himself up.

The thick head kissed her wet entrance. He leaned over her, capturing her mouth in another bruising kiss as he began to push inside.

One slow, inexorable inch at a time.

Her virgin walls fluttered and clenched around the intrusion, resisting and yielding all at once.

Noella’s nails raked down his back as a high, keening whine escaped her as he sank deeper, stretching her open for the very first time.

When he finally bottomed out. Hips flush against hers, every inch buried to the hilt, red blood poured out, proof of her shattered virginity.

She hugged him with a choked sob, while her inner walls were spasming wildly in her first orgasm from penetration alone.

Egon groaned, holding perfectly still while she fluttered and milked him.

Then he began to move.

"Schlik. Schlik."

Slow at first, but long deep strokes that dragged along every sensitive inch inside her.

Then faster.

Harder.

"Paaah.paah.paah."

The desk creaked beneath them.

Noella clung to him, legs wrapped around his waist, mouth open in a continuous stream of broken pleas and moans.

"Ahh. Ahhh, ahhh."

And Egon, grinning like a conqueror, behan to fuck his newly bound sister-in-law exactly the way she had begged him to.

Thoroughly, mercilessly, and without mercy.
