Rio grins and gives a playful growl. "So, what did you expect when you were buying me, Master?" He says, snuggling up to her, trying to be cute and cuddly.
Theresa opened her eyes and smiled at the wolf, rubbing his ear between her forefinger and thumb. "Certainly not that great stamina of yours." She laughed. "Or your massive amounts of cum. You leak like a faucet when that canine cock is hard. What were you expecting in a Master, if anything?"
Rio gives a laugh, nibbling on your neck. "Father said from your profile you would like those things, especially lots of cum." He says, rubbing her side. "All Father said is that my Master would be very beautiful and I would be happy. He was wrong." Rio kisses her neck, murring. "You're amazing."
Theresa laughed at his statement. "Oh, how your Father was right." She shivered. "Just the thought of all those gallons of cum being squirted so deep inside me..." she closed her eyes and bit her lip. "The feeling of your hot sperm shooting again and again..." She shook her head, coming out of a daze. "They did well with you, Rio."
The wolf's tail starts to sway happily at her praising him. When she's in her daze, he leans forward, kissing and nibbling her neck. "Mmm, so, Master prefers my cock in her ass, right?" Rio says, grinning playfully, giving a little growl.
She leaned her head forward, giving his shoulder a light bite. "Oh yes. Your hot cock feels so much bigger inside my tight asshole...but I do enjoy how your giant knot presses against my g-spot when you're balls deep in my cunt." Theresa's hands reach around, squeezing his butt cheeks. "Do you like being inside of me, Rio?"
She could feel the tip of his large canine dick against her thigh as she squeezes his ass. "Y-yes, Master. Very much so. It's my favorite thing, better than my favorite meal or treats." The wolf says, licking her neck excitedly.
Theresa raises a brow as the wolf rests her hands on his growing member. "My, my. Someone's getting feisty." She squeezes his cock in both hands, acknowledging it, but withholds from stroking it.
Rio presses up against her, turning her over flat on her stomach. Putting his paws on her ass, parting the cheeks, rubbing his drooling cock over the tight, pink little asshole.
Her eyes widened in surprise as he turned her over, splashing water over the edge of the tub. She groaned as he parted her ass cheeks, her hands gripping tightly onto the edge of the bath.
As she holds onto the bath, the wolf starts to push his cock into her ass. Having gotten the hang of it by now, it wasn't hard for him to slide his entire shaft into her ass and begin to pump himself. The water splashed around the two of them, making a mess as his large, hard canine dick goes deep into her tight hole. "A-ah! It's so good!"
Theresa moaned as his cock penetrated her ass, flooding it with warm water from the tub. She tried to thrust back, but how he had her only made her knees hit the bottom of the tub, her legs floating uselessly under him. "Rio!"
He slaps her ass as his cock sinks deep into it. "My Master is a kinky girl, isn't she, enjoying anal more than vaginal." Rio says, growling playfully. "If lots of girls liked anal, I would've been taught that, so you're a dirty, perverted girl, aren't you?" He asks her as he fucks her harder, the knot pushing up against her tight hole.
She moaned as he thrust in and out of her ass. "Y-yes. I'm...so dirty! Oh God! Fuck, Rio." She groaned as his hard, hot wolf dick worked further inside of her, the knot plunging into her asshole. She began to tense. "Ah! Your...your knot! Its inside me!"
When his knot slides into her ass, Rio lets out a loud howl as it swells in her. She can feel the knot getting bigger and bigger until it was the size of a softball inside of her ass. Shortly after, her squeezing ass pushed him over the edge and he began to cum inside of her, pouring his seed into her ass.
Theresa whimpered as her orgasm crept up on her, squeezing the swollen canine's knot inside of her tight asshole. She moaned as he spurted his hot cum inside of her, just hoping she didn't pass out again. "Ah!" She squirmed around his hot, twitching cock.
His cum spills into her, making her stomach feel warm as he fills her. The girl can feel the absurd amount of cum flowing into her, as much as he'd ever cum before. Slowly coming down from his orgasm, he pants heavily, sinking down atop of her back.
She huffs, pulling herself against the side of the tub, not wanting his weight to push her under. The feeling of his cum spilling deep inside of her and filling her, almost stretching her is unbelievable. Her pussy and ass are still convulsing from the aftershocks of her own orgasm. "Rio!" She looks back at the canine. "Are you trying to drown me?"
Rio gives a huff, pulling up from her. "Sorry, I just kinda relaxed a little too quickly after I finished." He tells her. Slowly, gently pulling out of her, Rio lays down in the water again, letting the hot water relax him after he just came. Murring softly, he closes his eyes, at least content that he didn't need to clean.
Theresa smiled, laughing at the wolf as she turned over and sat up, tensing her ass to keep his cum inside her. "I understand that. Next time we have sex in the bath, I'm on top. I don't want any near death experiences."
Rio gives a laugh, shaking his head. "That wasn't even close." He says playfully. Unplugging the bath and letting it drain, he got a big fluffy towel, meticulously drying his fur so he wouldn't smell like wet dog. "What are our plans for tomorrow, Master?"
