"Face down, ass up" by Kulkum
“Still surprises me, how tight you are,” the wolf murmured as his finger slipped deeper into the blazing heat of his lover’s body. “Yeah, I know. ‘It’s a feline thing.’ I’m just sayin’, it’s certainly a bonus that you’re bigger than me but still tighter than a virgin on prom night.”
The growl that escaped the tigress at the comparison would have made him reconsider his words, once upon a time. Now the low rumble, which he could feel vibrate through his paw as her soaked folds clenched around him, only caused him to chuckle softly. The hand on her tail came down on her rump once, the fur muffled swat causing the growl to fade into a whimpering moan as he flexed the thick finger inside of her.
“What was that?” he asked, his tail wagging silently behind him when his partner gave no reply other than a failed attempt to growl again. So he swatted again, this time grabbing a pawful of tiger butt and squeezing as he allowed his paw to thrust against her slowly. His face hardened slightly when she turned to glare at him, a tactic that only had him slipping his finger free as he gave a shrug. “Was that… You don’t want the knot tonight?”
The raised ass of the powerful tigress squirmed as her paws, which were free, gripped the bedsheets as she shook her head, then ground it into the sheets as if trying to free herself of the pesky muzzle. A low growl of his own rose as he placed both paws on her rump, spreading her pussy as he let her feel the throbbing length of canine arousal rest between her cheeks. When she tried to raise onto all fours, his growl deepened as he reached forward to push her chest back into the sheets.
“Keep your ass up, partner,” he said, drawing his hips back until the tip of his cock nestled against the mouth of her sex. This caused her to obey, looking back at him with her cheek on the mattress even as she raised her own tail. “But if you growl again outside of an orgasm, no knot-cuddles for you.”
A second later, the female’s very feline yowl of delight filled the room as he dragged her larger body back to sink himself into the incredibly wet and tight heat of her sex, driving himself forward to meet the motion until his hips slapped against hers. He had never expected Fangmeyer to be into muzzle play, but as the first of what he knew would be multiple orgasms rolled through her, he certainly wasn’t going to complain about being the alpha now and then.
