Blake never had much interest in meeting the parents of any previous partners she’d dated, but Yang was an exception. Things were starting to get serious between the two girlfriends, so they both agreed it was time to finally break the ice and make nice with the future in-laws. The first stop on their trip was the small village of Patch where Yang and Ruby’s father Taiyang lived a quiet life. Blake could hardly believe that someone who’d raised such an adventurous hothead like Yang would choose such a modest life, but she also couldn’t wait to see how similar father and daughter were.
What Blake didn’t expect was that they’d both have similar tastes in kitty fucktoys.
“Ohh! Ohh fuuck! S-slow down! She’s guh-gonna hear us!” Blake tried to keep her voice quiet, but she couldn’t hold down the hot passionate moans flowing from her mouth. Getting bent over the kitchen counter, silverware and utensils clattering as her girlfriend’s dad plowed her juicy snatch, just felt too damn good. And delightfully sinful.
“You’re the one raising your voice,” hissed Taiyang, emphasizing his point by giving Blake a firm slap on her bare ass. A move which only make the catgirl’s feminine voice even more high pitched. “Does my cock feel that good? Can’t help but let the whole house know how good it feels to be a cheating slut.”
“Unnf, yessshhh,” slurred Blake, her tongue rolling out to lick the tabletop. “Guh-geewwd… caaawwwk…” Unable to hold herself together any longer, the raven-haired faunus squirted an orgasm all over the floor, her sticky fluids dripping down her own legs as well as Taiyang’s.
“Bah, you damn slutty bitch.” He gave her another spank, and immediately felt her spasming orgasmic pussy clench tightly around his prick. So Taiyang did the only reasonable thing – spank her again. Then again and again, each time making Blake squeal like a stuck sow while massaging his throbbing cock. “What a mess you’re making in my kitchen. I ought to make you lick all that up. Or maybe Yang ought to do it instead.”
“Yang?” Blake’s ears twitched atop her head, recognizing something that was once familiar to her. “Huh… Wh-who – Nyaahh! – is Yang?”
Taiyang just chuckled and continued to pulverize Blake’s tight cunt into his tamed bitch-pocket. “Such an unfaithful girlfriend. Maybe you’re not good enough for my little dragon. I ought to just keep you for myself.”
Blake’s pleasure-fried mind still didn’t exactly comprehend what exactly Taiyang was talking about, but somewhere in the deep recesses of her melting intelligence she did understand the idea of getting fucked more by him. “Pleaaase,” she mewled submissively, thrusting her ass back against him so hard that her fat cheeks clapped. “Breed…. Breed meee!” Her animal brain had completely taken over, and now it demanded the virile seed of a male strong enough to claim her.
Another punishing spank then Taiyang tightly gripped Blake’s narrow waist, his thumbs digging into the dimples on her back, and yanked her back hard as his cock twitched and spurted hot creamy ropes of breeding juice into the howling faunus. “Fine by me! I think you and Yang would be pretty good parents… And I’ve always wanted grandchildren!”
