Face down, ass up

"Down," he told her, the word coming out a little more gruffly than he intended.

Holding her by the rope tying her arms behind her back, he lowered her forwards onto his bed, forcing her ass high into the air.

Unable to wait any longer, he took off his trousers and got behind her. He reached for the bottle of oil he never got around to moving back to the kitchen and liberally coated her crack, from her tailbone all the way to her cute little balls, tight in their pouch.

Lucas was surprised to see her hole already winking at him and chuckled. "Eager for my dick, aren't you, pet?"

Her only response was a muted whine and a sensual wiggle of her ass, but it was all he needed.

He took his cock in one hand and guided it between her cheeks, teasing her by sliding across her hole but not quite entering. Wordlessly, she pushed her hips back at him.

However, it wasn't long before his patience ran out, and so he finally set the head of his cock against her slick entrance and slowly pushed inside.

She tensed and inhaled sharply the moment the fat head popped through her sphincter. The rest of his dick slid in with relative ease, her insides quickly adjusting to his girth.

"Mmmhhhh," she moaned, her voice full of ecstasy. "Nnnggg!"

Her tunnel felt blissful as its velvety walls clenched and unclenched around his cock, but he wanted more. He grabbed her hips and pulled all the way out before plunging back in with one smooth motion.

Lucas settled into a rhythm, his pelvis smacking against her ass. With every thrust her face pressed into the mattress, but he held a firm grip on her bonds to keep her from sliding away from him. His heavy balls smacked against her smaller ones, driving him wild. Every sound, every sigh, every grunt or gasp she uttered drove him closer to the edge.

"Good... good pet..." he groaned. His mouth hung open as he panted and sweated, lost in the moment of fucking the bound and gagged and helpless body beneath him.

His thrusts became faster and more erratic as his orgasm approached, far more quickly than he would have liked. He felt his balls tighten and a heartbeat later, he peaked. His cock twitched and pulsed, spewing a thick, white stream of cum deep inside her.

He groaned as he filled her with his seed, gripping the ropes tightly. Another thrust or two and he was done, collapsing on top of her, panting hard. She whined in response, rocking her hips back and forth in an attempt to bring herself any kind of relief, but he pulled out of her, leaving a trail of cum leaking from her ass.

It took Lucas a long moment to regain his strength, then he undid Eldwyn's blindfold, then removed her gag, and finally untied her arms. She worked her jaw and arms, but once she got some feeling back into them, she reached down.

"What do you think you're doing?" Lucas said, causing her to freeze with her hand hovering just shy of her still erect dick.

"I-I want to finish," she whined, belatedly adding, "sir."

He put a finger under her chin and lifted it until their eyes met. "And if I said 'no'?"

She gulped before answering. "I would... I would accept it, sir."

"You would?"

"Yes, sir."

He grinned maliciously. "Then I'm saying no."

Her eyes widened. Clearly she hadn't expected him to go through with his threat. "But sir—"

"Are you still mine?"

"I... Yes, sir. I'm—I'm yours."

"Then don't argue. Come here."

He wrapped an arm around her, pulling her close. "You were wonderful," he whispered, "but I'm not going to let you cum tonight. Accept it like a good little pet."

She whimpered but didn't argue, instead burying her face in his chest. He could feel her dick rubbing against his thigh, and though she gasped at the contact, stopped herself from moving it any further.

Over the next quarter bell, it softened, agonizingly slowly. Lucas just held her, gently caressing her hair until finally it lay flaccid against her stomach.

"Good girl," he whispered, pressing a light kiss on her forehead, "now go to sleep."

Eldwyn didn't argue.
