It's been a long, rough week for Sin. So much has happened, and it's been wearing down on his normally happy and perky personality. Now, with a day to himself, he's decided he wants to relax and unwind; to take some time to himself so he can rest and recover after the week he's had.

And he knows just who he can go to for help with that.

The black and red cat, presently in his feral panther form, pads to Apartment 1028 and headbutts the door to knock on it. He knows his friend is home, and he can't wait to share a visit with him.

The door soon opens, and an anthropomorphic housecat peeks out, smiling as soon as he sees Sin. "Oh, hey! Please, come inside!"

The panther returns the smile with one of his own. "Hello, Ly; thank you. Sorry to show up unexpectedly, but it's been a rough time for mew."

Lysergia's expression lowers as he pets the other feline behind his ears. He's normally amused by Sin's habit of using 'mew', but right now, he can tell there's a lot on his mind.

"I'm sorry to hear… Would you like something to eat, hun?"

Sin shakes his head. "No, but thank you. Honestly, I just want to rest for a while."

The housecat offers a gentle smile. "Well, that's something I can certainly help you with."

He pets the panther on his shoulders. "Would you like somewhere cozy and safe to-"

"Oh yes please, mew would love that very much."

Ly can't help but chuckle at Sin's eagerness. "Alright, silly. How about you change into a smaller form for me?"

The panther's eyes close without hesitation, and in an instant, he's surrounded by brilliant red flames! When they fade, he's turned into a mouse-sized housecat, only a few inches long!

Lysergia smiles, petting the tiny feline. "Mmm, that'll do!"

And knowing precisely where Sin wants to be right now, he chuckles and lowers his sweatpants, revealing his naked lower half! He lies belly-down on the floor, legs spread on either side of the tiny cat. "Go ahead and climb inside when you're ready, hun. It's safe, warm, snug, and all for you." He smiles. "I'll keep quiet, okay? Just focus on my insides all around you. I'll keep you safe, I promise."

Sin doesn't need to be told twice – Ly's butt is one of his favorite places to hide from the world!

He pads close and gives the black pucker a few licks, getting it nice and wet. He loves how inviting that hole is, and it isn't long before he starts nuzzling against the rim, sinking his head into the velvety-soft indigo flesh beyond!

Lysergia bites his lip and shivers softly at the sensations of his tiny friend climbing in, and he reaches a hand back to help guide him past his snug anus and into that cozy rectum calling to him.

"Mhhf… So warm… Mew needed this…"

The larger cat giggles softly, beginning to deeply purr, both from the insertion and from the knowledge that he's helping his dear friend have that comfort he's so desperate for!

As Sin squirms further into Lysergia's soft rectum, he feels himself beginning to relax already, the stresses of his week practically melting away into the soft flesh around him. The walls flex and squeeze softly, giving the tiny feline a warm and slick sort of massage while coaxing him to wriggle his way deeper inside.

Soon, with a faint squish, the last of the cat disappears into Ly's rear, at which point Sin nuzzles the silky-smooth walls cradling him. He's completely hidden – Completely safe. He knows Ly won't allow anything to hurt him. And as the rectum pulses, idly squishing him even deeper along, he knows he has nothing to worry about. Nothing outside of his friend matters anymore. Just Ly and his warm insides.

Curious to go along with the subtle peristalsis working seemingly in reverse, Sin lets himself be brought further in. The rectum turns downward briefly before curving upward, bringing the cat through the segmented haustra of Ly's colon – All of which seem eager to guide their passenger along!

Too focused on the enjoyable sensations of those walls seeming to embrace him in a warm and squishy hug before guiding him to the next segment, the tiny feline quickly loses count of how many haustra he passes through. Not that it really matters – It's all so wonderful, and he doesn't really care how long this lasts. He just wants to enjoy every moment for as long as he can.

And the soft, cradling caresses of the large intestine squeezing and massaging over him are certainly making every last second worthwhile!

Sin's ascent eventually takes a right-angle turn sideways as he begins to wiggle through the traverse colon, and he shivers in delight as he feels it sag ever so subtly beneath his weight. He imagines it almost like a fleshy hammock made just for him, and he truly can't be happier with how delightful this is!

Squish after squish, squeeze after squeeze, the tiny cat is guided from one haustrum to the next – Each one giving him a snugly hug with those slick walls, as though to affirm just how much Lysergia loves him and cares for him.

It's nothing short of blissful.

The sideways movements, after a while, begin to angle downward as he lowers through the ascending colon. But other than the change in direction, not much different happens – Squish, squeeze, caress, then to the next haustrum to repeat the process. Sin feels like he could just fall asleep in here, so very deep within his beloved friend.

After what feels like a pleasure-filled eternity, Sin slips into the last section – Ly's cecum.

From outside, Lysergia finally breaks his silence, speaking to his occupant. "Mmh, you're so deep in me… Do you want to stay there? Or would you like to keep going?"

Sin looks around to explore his present surroundings. The walls are slightly folded but otherwise perfectly smooth, and he spots two holes in the flesh around him. The one at the base of the pouch is no doubt the cat's appendix. But the tiny feline is more interested in the one partway up the wall. Much like before, he nuzzles against it before pressing his paws delicately inside, starting to climb through the ileocecal valve and into Ly's small intestine!

"Mhhf… Suppose that answers that!"

With another faint squish, Sin breaches through into the much narrower tunnel, where he's surprised to find the peristalsis working more strongly to guide him through the twists and turns of the long maze of intestine.

These walls feel much more active than the large intestine's were, actively kneading and massaging the tiny cat while bringing him deeper. His surroundings are fairly smooth right now, but he knows that will change any minute.

Sure enough, after a bit of time, he feels a slight wiggle against his body, followed by another – And soon, countless fingerlike villi are tickling and stroking every tiny inch of his body like little feelers! Sin can't keep from giggling and purring, the wiggly squishes working out any last trace of stress and worry about anything beyond his friend's insides.

The villi don't tickle too much, ensuring the feline won't be overstimulated. Instead, they mostly stroke and caress everything they can reach, and it makes Sin feel like he's being pet over his entire body all at once by the softest fingers he's ever felt.

It's truly incredible!

Though the relaxation is beginning to get to him, the warm coziness of the intestine lulling him to rest, he forces himself to stay awake, wanting to enjoy every moment of this without risk of missing anything.

Sin mentally tries to map out the twists and turns of Ly's small intestine, finding the shape of the tangle of tubing quite interesting – Especially from the perspective of being actively squished through it.

Time loses all meaning as he's guided along. He has no idea if it's been a few minutes or a few days since he entered his friend, but he doesn't care. The comfort and love have all been so very much needed, and he utterly loses himself in his surroundings.

The only sign of his current progress is the gradually increasing volume of a rumbling purr somewhere above him. He smiles, happy to know Ly is enjoying himself just as much as he is!

For now, he contents himself to nuzzle into the villi, letting them stroke his face as he worms his way along, guided by the peristalsis within the larger cat's small intestine.

This goes on for quite some time, but after another pleasure-filled eternity, Sin squishes against another valve, which readily opens to accept him through. He wriggles through the cat's pyloric sphincter until he squishes into the stomach beyond.

His journey is over. He's arrived at his friend's belly. Right where he wants to be.

Right where he belongs.

The soft groaning of the stomach adds a nice ambiance to go with the steady purring all around him and the firm heartbeat of a very contented cat.

Sin almost can't tell whether the heartbeat is Ly's or his own – They seem to pound in perfect time with one another.

A faint pat against the belly catches Sin's attention before Lysergia speaks once again.

"All good in there, hun?"

The tiny cat purrs, nuzzling the folded rugae of the belly around him. "Yes… Mew is safe inside. Thank you, Ly."

A chuckle rocks the stomach a bit. "I'm glad. You felt amazing going through me, you know…"

----------

Outside, Lysergia smiles, caressing his belly nice and softly as he lies down in bed, pulling a blanket over himself.

"Stay in there as long as you need, buddy. I won't let anything hurt you. Just rest and relax as much as you'd like."

He yawns, closing his eyes, before muttering "Love you, you wonderful mew."

And faintly from his tummy, Sin responds "Love you too, friend."
