Chapter Text
If there was one word to describe surviving an estrus cycle, it would be “endurance”. Hero found that out first-hand. His first time with Mari was certainly one of the highlights of his summer. His girlfriend thought so too, to the point where neither could get that night out of their minds. Hero would have recurring wet dreams of the catgirl, while Mari would waste much of her bath time tail-fucking herself in an attempt to relive the moment. (Sunny would not be amused.)
Two days had passed since that night, along with two days of agonizing horniness for the catgirl. She craved another session with her dogboy. The entire experience of being knotted was her favorite part. Unfortunately, her estrus was ending soon. Fortunately, her mother trusted Hero. She set up Sunny to have a sleepover at Kel’s house, while she and her husband were out for work.
Hero’s mother was also alerted to “Mari’s predicament”. As a hybrid of an estrus-species herself, she sympathized with the girl. In fact, she gave her oldest son a tip before he left.
“Since it’s her last day, make sure it ends with a bang.”
Hero blushed at the implication, before quickly making his way towards Mari’s place. Once he opened the door, a pair of hungry soft lips shot onto his. Hero was pulled in by her weight, making sure to shut the door behind him. With her house being so close, he had no need to take off any shoes.
“Phew, you’re eager today.” Hero managed to comment between kisses.
Mari didn’t reply. She was just too horny to really think straight. The catgirl tugged her dogboy all the way back to her room’s bed. She nearly tore their clothes off with how fast she was pulling and scratching. Once Mari pulled off his briefs, however, she let out a yowl of disappointment upon seeing nothing but his furry sheath.
“I thought you would be ready,” the catgirl whined.
“Well, I did have dreams of you…” Hero admitted bashfully. “…though my dick was pretty tired after them.”
That wasn’t going to do in Mari’s mind. Her fingerpads immediately went to work, pumping the sheath and fondling his scrotum until she saw the red rocket’s tip poke out. At that point, she peeled the rest of the sheath down his penis, exposing the full rod. Then she grasped her hand around the bare phallus and pumped it to full hardness. Hero released a series of high-pitched whines during the entire process.
“There we go,” Mari purred. “That’s more like it.”
The dogboy felt her breath grow hotter on his rod. But tonight, his eyes sparked with a gleam of mischief. His blunt claws gripped her hips, before flipping her flat onto her stomach. Hero got himself off the bed, facing towards his girlfriend’s ass.
“MYA?!” the cat hybrid exclaimed when her face hit the mattress. “Henry, what are you-“
Hero immediately made his girlfriend purr by scratching the sweet spot on the base of her tail. It made her prop her buttocks up on her knees, presenting her slick, puffy vulva.
“RRrrrrrrr…” To beckon her dogboy further, she clenched her asscheeks for a few twerks.
“So you want my knot, huh?” the dog hybrid teased.
“Mmmmrrrrrr… you know me so well…” Mari slurred.
“Well, you’ll have to wait a bit.”
The catgirl stopped purring. “Huh?”
“I won’t give you my cock just yet.” Mari looked back to see a smug grin across Hero’s face.
“Hero, come on.” She pushed her black-furred asscheeks between his canine cock. “Just give it to me.”
“Nope.” Hero pulled his dick away. “Not till I know you’re ready.”
“Henry, I’m on the last day of my heat,” Mari said impatiently. “I don’t think you need any other reason.”
“That won’t stop me from doing this.”
The dog hybrid brought his lips to her pussy (pun intended), inserting his tongue first. Mari let out a squeal of delight, her tail shooting straight up.
“YES, HERO! YES!”
Hero felt her perineum grind onto his human nose, savoring the musky smell. It only made sense that after getting his first oral, that she would get her first as well. He made sure it was the best he could muster, writing letters within her vagina with his tongue and applying suction to her clit below. While Mari was wet before, now she was soaking, with more fluid pouring into Hero’s hungry mouth with each passing second. Mari’s heightened state of arousal brought her closer to orgasm, clenching around his intruding tongue.
“Henryyyyy-“
Suddenly, the tongue left.
Mari released a pained whine. “What the hell, Hero?!”
“That’s what you get for blueballing me,” Hero teased.
And then, out of nowhere, he stood up, plunging his still-hard dick in with one thrust. The cat hybrid yowled in pleasure, her claws digging into the sheets. Placing his handlike paws on her hips, he started thrusting doggy-style. His pulsing red rocket went in and out of her dripping vulva like a piston in an engine.
*PLAP-PLAP-PLAP-PLAP-PLAP…*
“Hah-hah-hah-hah-hah…”
Mari’s mind was on the moon. She didn’t mind getting dominated as long as she continued to feel his knot slapping against her clit. The catgirl swore she felt the flat blood vessels on her vaginal rugae. The friction was electric and firey at the same time, leaving the cat hybrid a moaning mess.
Hero wasn’t finished, however. If this was truly the last day of her heat, then he would take his mother’s advice. He gradually pressed harder into her vulva, making Mari’s mewls progressively louder. Until…
*POP!*
“NYAAH!”
…the catgirl finally got what she was thirsting for 2 days.
But little did she know, Hero wouldn’t stop there. He pulled out, creating another wet “pop” when he did so. Then he slipped it back in. And out it went again. He continually fucked his girlfriend on just his knot, knowing full well that was her favorite part of the experience.
*POP… POP… POP… POP… POP…*
“Ah…hah…ha…hah…hah…”
Unlike his previous thrusting, Hero kept his pace consistent this time, waiting for his lover to cum first for a change. Once he felt her vagina clench the hardest he could, he kept his bulbis glandis in.
“MYAAAAAAAAAAA!!!!”
*POP!*
“Hngh!” Hero grunted when he felt his load shoot into her orgasming womb, a tie forming between them.
With both of them worn tired, Hero laid down on the bed beside Mari, spooning and pulling her close with the expanded knot stuck in her vagina. She lazily turned onto his torso, savoring the contact between their skin and fur.
“Hah… what’s gotten into you today?” she asked.
“You wanted… my knot… hah… so I delivered,” Hero said with a loving grin.
“But I wanted to top,” she whined. “Bad dog.”
“Aw, come on,” the dogboy said. He gave his girlfriend a loving scratch on her ears, making her purr. “I gave you the best night of your life, and this is how you thank me?”
“Well…” Mari leaned into his touch. “It was pretty nice…”
Hero let out a wide yawn. “Say, you wouldn’t mind if we showered before bed, right?”
“Sure,” the catgirl shifted her hips a bit, savoring the stuffed feeling. “I wouldn’t mind one bit.”
