Dog Pound

Zwei eyed Ruby as she slept. It was almost too easy. She was wearing her loose-fitting pajamas and was sleeping on her belly, her rump turned up and quite visible through the thin fabric. It was as if Ruby was inviting him to exert his dominance over her. Which was fitting enough.

He closed his teeth around the waistband of her pajama bottoms and started tugging them down. They slid off her smooth butt easily enough, but getting them down her thighs was a bit more difficult. Still, he had a duty. A little hard work wouldn’t hurt.

Ruby shifted slightly as her pajamas slid to mid-thigh. “Yang,” she moaned drowsily. “Not tonight. I’m sleepy.”

Zwei ignored her, hopping up onto the back of Ruby’s thighs. He pushed his paws against her plush buttocks, spreading them apart and exposing her tight pink pucker. There was his goal. Admittedly, breeding her would have been a clearer statement of his authority, but so long as she was mounted his point would be clear.

He licked his chops and pushed his muzzle between her soft cheeks, eliciting a gasp of surprise as his wet nose pressed against the tight hole. The gasp turned into another moan as he started licking intently at his bitch. He smelled her arousal building. A good bitch always got excited when an alpha staked his claim on her. Starting with her had been a good idea.

No hesitation then. He would have time to savor her newfound obedience later. He climbed up onto her large hips. How was she so round around the bottom if she was so scrawny around the hips? No matter. He pressed his chiseled tip between her cheeks and pushed it upwards until he found the hole he had prepared.

One hard push and his tip stretched her asshole open. Ruby’s head shot up off her pillow with a yelp. Zwei’s back hunched. And just like that, he was hammering his pelvis back and forth while his furry nuts bounced against her buttocks.

“Zwei! What are you doing?! Stop!” Ruby appealed to the dog in a panicked whisper, hoping not to wake her roommates to find her in such an embarrassing position. Zwei snarled silently. Stop? He had no plans to stop. He was right, of course. She needed discipline. She needed to understand that she was in no position to give demands. He hooked his stubby forelegs around her hips, giving him the leverage to mate her harder and deeper.

Ruby whimpered underneath him. She buried her face in her pillow, hugging it tightly and trying not to move. Weiss was in the bunk right under her. If she tried to shove him off or roll over, the movement might wake her and she would raise an indignant ruckus that would wake Blake and Yang as well. She had no choice. She just had to endure Zwei’s attentions and stifle her moans of pleasure until he was finished.

And the pleasure was insane. His hips were pumping so fast! She could hardly catch her breath as he roughly mated her virgin asshole. Was Zwei really as large as he felt or was it just her inexperience making him feel so large, stretching her wet anus like he was? It was so wrong. She shouldn’t be enjoying this so much. Yet her toes curled as her dog’s hips repeatedly slapped against her butt.

“Zwei, please!” Ruby quietly begged, ashamed in the lust she could hear in her own voice. Her heart sank as she realized her arousal was no doubt forming a stain on her sheets. “What if the girls see me like this? We have to stop!”

Zwei growled, thrusting even deeper into his rightful bitch. Let the others wake up. Let them see you in your proper place under me. He didn’t care about that. His only concern was that he was approaching his goal. And from the scent, Ruby was rapidly reaching her climax as well.

Ruby stuffed her face into the fluffy pillow just in time. Hot. So hot. Zwei had finally stopped thrusting. But in exchange for this small mercy, a new torment overwhelmed her in the form of a hot stream of thick dog jizz. She couldn’t help herself. Her entire body started trembling as she felt her pussy shamefully squirting.

That’s when a new problem made itself known. “Zwei! It’s getting bigger!” Ruby pushed her rump higher, seeking relief from this new pressure. But there was no relief. The knot at the base of Zwei’s cock would not be denied as it swelled inside her. How big would it get? It seemed to go on forever, stretching her abused little hole. Zwei was still cumming inside her. His knot was swelling to seal the hot cream in. Ruby bit down hard on her pillow to muffle a scream as her neglected pussy continued gushing.

When Ruby regained her senses after whiting out for a few seconds, Zwei had reversed his position. His hind paws were planted firmly on her butt cheeks as he pulled and tugged, trying to free his dick. “Zwei, stop. It’s too tight. Just leave it inside until the swelling goes down, please.”

Again, Zwei ignored her, tugging intently at their join. Ruby panted, trying to endure. Her already sore asshole stretched wider, wider, unbearably wide, until.

Pop!

Another small orgasm threatened to knock Ruby out again as Zwei’s cock came free at last. But a whispered voice snapped her to full awareness.

“Ruby? Are you okay?” Yang whispered from her own bunk across the gap.

“Y-yeah, I’m fine. Just uh. Just a dream.”

“Well try to keep it down, alright? If you wake Weiss we’ll never hear the end of it.”

“Yeah, sorry.” Ruby settled back into bed, her skin covered in sweat. She hurriedly pulled her panties and pajamas back into place, wincing as she felt the cloth press the sticky mess against her skin. There was nothing for it. She couldn’t get out of bed now. As gross as it felt, she would have no choice but to wait until morning so she could shower.

Zwei sat contentedly on the bed cleaning himself. That had gone exactly to plan. One bitch properly disciplined. Three more to go. With a pleased chuff, Zwei curled up next to his bitch to get some much-deserved rest.
