"Hold up, hold up. You want me to what?" Little Cato asked, surprised as he sat in the reclining blonde's lap in his room, giving him a peculiar look with a raised eyebrow. Everyone was out on a supply run and these two were left to look after things, despite their half-hearted protests, which meant they had ample time for some fun.

However, being the quirky S.O.B he was, Gary felt today's carnal events needed a little change. An unexpected one at that.

"Yep," He nodded, scratching the kit behind his ears as he played with his moving tail. "I want you to fuck me this time around." He finished with a cheeky grin that made Little Cato feel a bit uneasy. He couldn't be serious, right? Sure, he's a moaning mess when it comes to Avocato's dick pistoning inside him until they both come undone, and when it was the other around, including when he got both of each on one occasion or more. But it was mindboggling that he would request the all-powerful BVC (as boasted by Gary) from his-er, their son at all.

I mean, the kid was only what, 13? Could his own dick really fill him up at his current age and size? Dude must be real desperate for Ventrexian meat if he wants it from a shrimp like him, the bastard.

"Really?" He asked, trailing a paw over one of the human's clothed nipples, giving it a pinch.

"Yes." His metallic hand goes to undo his belt buckle and pants.

"You want me to fuck you instead?" He repeated the question, shoving down his pants as well after moving to the side of the man, still unsure.

"Yes, really," Gary said, his tone sounding almost impatient after kicking off his pants and boots, leaving only his socks on, and spreading his legs. "Because we need to spice things up, small fry. It isn't a lot of fun that you're the only one getting the D in both holes more than me and Avo, so I thought it'd be the other way around."

The kit scoffed, his pants strewn on the floor with his boots before straddling the blonde who palmed his sack with his real hand, rolling his balls around and squeezing them gently, making him purr low before speaking up. "I get that, but would you even feel me in there at all? I'm barely even half dad's size."

"Dude, have you not seen the size of your own willy? At least now?" Gary pouted, flicking at his cock that slipped out. Rolling his eyes, Little Cato looked down and made an expression of mild shock, mouthing an 'oh shit'. His once 4.5 inched boyhood was now an impressive 5.7 with a touch of girth added to it, plus the bottled-up feel in his balls.

"Whoa, how'd I get a little bigger?" He wondered in amazement as he thrusted in the air a little, making his dick bounce in the air, with Gary licking his lips as his hand went from caressing the boy's balls to sliding along the underside of it as his own fully-erect dick twitched. The incredulous look he gave him snapped him out of it and he mused his hair in thought.

"Uh-um, I slipped a tiny portion of dick growth dust in your milk yesterday. Found it in Avo's secret stash in one of his ammo caches." He droned, watching mesmerized as the kit spun his penis around like a helicopter. "Don't tell him."

"Ok, ok." Little Cato mumbled before leaning up to kiss the blonde, who wrapped an arm around him to bring him closer. His hand goes to squeeze one of his buttocks as he felt his dick gyrate against his chest, making him moan softly and swirl his tongue around in his. While they kissed, his metal hand goes down to stroke his leaking hardness. When they parted, the kit gave him an adorable purr before slithering down in between his parting legs and burying his nose in his anus, taking in a good whiff of his scent. The blonde gasped softly at that and hummed.

"Mmmrrrah, dried cum and health toots. My favorite." Little Cato purred before giving the twitching hole a big lick upwards, smirking at the shaky moan his other dad made before doing it again and swirling his rough tongue around it in a circle that closed into the center, poking the tip of his tongue past the center and the already loosened ring of muscle. Gary hissed, biting his lower lip as his little Spidercat lubed up as much as his anal caverns as he could get, stroking himself faster along the way.

After he was done, Little Cato wrapped his paws around his torso and edged himself in slowly, his moan growing louder the further he went while the human exhaled shakily. After a moment of taking in the smooth snug feel of his anal caverns, he began to thrust his hips at a slow pace to test the waters. Gary panted softly, rubbing the back of the kit's head as his metal hand left from his dick to the bed to support himself. 

"Aah." The kit breathed, already picking up the pace from the nice warm, wet sensation all over his sensitive boyhood and thorns.

"Take your time now, bud. Keep the pace steady, savor the feeling." His other father instructed, moaning himself as the boy moved deeper, panting softly into his chest. Gripping his sides, he began to harden his thrust while keeping the same slow pace, making his father's noises go up a volume. He then slid out to the tip and slammed himself back in, making the blonde stifle a curse.

"You like that, dad?" Little Cato asked, blushing red.

"Mmhm." He nodded with a hum.

From there, he started to go faster. Their once quieted moans and gasps grew louder as the hand at the back of his head went up to scratch down one of his ears and go down to pat his back. Purring from the affection, Little Cato lifted his shirt up some and leaned down to suckle at his uncovered nipple, swirling his tongue around it as he did the same with his hips at swiveled around with the blonde moaning softly.

"There you go, Spidercat, just like that." He said, running his nails down his spine, closing his eyes, and letting out a small whine when the kit responded by biting down gently on his nipple before letting go with a pop and pistoning his hips against him even faster. By that point, the heavenly sensation from the human's entrance hugging his cock made him speed up even more, unable to hold his noises in any longer as he began to meow and moan almost blissfully every two quick thrusts.

"O-oh God, this is so weird." Little Cato groaned, hugging the blonde tighter. "Yet it feels so frigging good, mrrrrea..." He trailed off in a broken meow.

Gary couldn't agree more, even as the thought of a teenage man-cat doing him seemed strange at first thought, yet all the more enticing. Wonder how he'll do Avocato some time. He gave a small nod, rubbing his back some more as he bit his lip to the feel of the boy's impressive length pumping his insides. If he were to go deeper, he'd probably hit his-

"H-haaa... There." Gary suddenly gasped out as he felt a few inches of his dick graze his prostate, eventually moaning louder when it got hit some more. The kit thrusted into him hard enough that his balls smacked against his rear, which sounded off in the room, which was thankfully soundproof considering KVN was in the next room in stasis mode. Yeah, they weren't completely alone, but thank God even robots sleep.

"Fuh...fuck yeah." He moaned out loud, ramming into the human's hole at full speed. "Fuck, this feels so good."

"I know it does. That's how fucking someone feels." His father said back, holding the back of Little Cato's head to his chest as he laid down on the bed, making his cock pump at an angle he loved the most. "You getting close by the way, bud? You've lasted pretty long."

"G-getting there, unh." The kit grunted, gripping all he could get of his thighs, never slowing down, and giving Gary the most aroused look he could muster. His tangerine-furred face flustered and matted with sweat, his eyes half-lidded, and his drooling tongue hanging out. If Gary knew one thing about an intense orgasm, it's that it comes through immediately after seeing a Ventrexian kid giving you that ecstatic look as he fucks you in the ass.

"Oh, Little C...Cato!" The blonde moaned shakily as he closed his eyes, releasing all over his naval and Little Cato's paw, once he grabbed his cock to get most of it up. He couldn't help but watch as the kit licked his excess off while pounding him still. "So hot..."

The salty taste of human seed made him hum and meow lustfully as his hips worked in hyperdrive for minutes on end as he went to get the rest of it oozing down his shaft.

When he managed to slurp up almost all of his release, he began to slow down as he groaned, nearing his orgasm at long last. Holding him down to his chest, Gary only shuddered and hummed while the Ventrexian snapped his hips into him, his eyes closed.

"G-Gary, I'm almost there, I'm almost there!" He whimpered.

"Give me everything you got, babe." Gary encouraged in a soft shuddery voice. The kit then started thrusting shallowly into the human a few more times before h planted himself flush to his rear.

"Oh, daddy!" He moaned in a high-pitched, almost feminine voice as he came, with his father moaning with him. Each semi-large rope of cum drenching his internal caverns before the boy laid there, his chest heaving against his stomach. While he recovered from his climax, Gary softly rubbed his ears down to his back, feeling him purr in his chest.

"How was your first time topping?" He asked, stroking an ear.

The kit looked up at him with a tired smile, "Mmm, wonderous."

"Yeah. Real wonderous."

They cuddle on the soiled bed while unbeknownst to them, Avocato sat against the wall a room away from them, his spent cock in paw, and a nice little puddle from where he spilled, flustered.

"Gary, you fucking genius." He huffed.
