In Tamaki's dorm room

Tamaki was blowing his nose and sniffling while Mirio tried his best to tend to his boyfriend.

Mirio: "Need anything else, love?"

Tamaki: *sniffs* "A-a kiss?"

Mirio grins and kisses Tamaki on the cheek before walking off.

Tamaki: "Wait! Where are you going?"

Mirio: "Down to the kitchen, I'm gonna make some soup."

Tamaki sneezes as Mirio heads out to the common room and into the kitchen.

Mirio grabs all of the ingredients and whips up some soup for Tamaki.

Mirio: "This should get the sickness out of his system!"

With a bright smile on his face, Mirio grabs the bowl of soup and enters the elevator, making his way back to Tamaki's room.

Mirio: "Tamaki! I'm back!"

Mirio enters Tamaki's room only to notice the dark haired boy's flustered face.

Tamaki's face was flushed red and he avoided eye contact with his blonde boyfriend.

Mirio: "What's the matter?"

Tamaki: "N-nothing!"

Mirio was visibly concerned, so he walked over to Tamaki's bed and noticed the timid boy's erection.

Tamaki: *gasps*

Mirio blushes at the sight of Tamaki's boner, making the dark haired boy feel even more flustered.

Tamaki: "I-I was just thinking about the last time we..."

 Mirio's surprised face slowly transitioned to a seductive smirk as he crawled in bed with Tamaki.

Tamaki: "M-Mirio?!"

Mirio: "Don't worry, Tamaki- I'll make you feel even better than last time~"

Mirio stripped Tamaki of his pants and underwear before spreading the dark haired boy's legs and revealing his dick and hole.

Tamaki: "W-what are you gonna do?"

Mirio licked Tamaki's hole, making his timid boyfriend gasp softly.

Mirio continued licking in a circular motion, earning even more gasps and moans from Tamaki.

Tamaki: "A-aah~"

Mirio: "Mmmm~"

Mirio suddenly slid his tongue halfway inside of Tamaki's hole before rolling it around and exploring the inside of his boyfriend's ass.

Tamaki's hole was soaking wet inside and out from all of Mirio's licking.

Tamaki: "Mirio... p-please~"

Mirio abruptly stops licking, both surprising and slightly upsetting Tamaki.

Tamaki: "W-why did you sto-"

Mirio squirted some lube onto two of his fingers before rubbing them together.

Mirio: "You ready?"

Tamaki: *gulps* "Y-yes."

Mirio steadily slid his lube-covered fingers inside of Tamaki's ass.

Shocked by the cold, sticky sensation of Mirio's fingers, Tamaki's eyes widened and he let out a gasp.

Tamaki: "A-ah~!"

Mirio: (Tamaki is so cute!)

Mirio used his fingers to play with Tamaki's hole, rubbing them against his insides and sliding them in and out of his hole.

Tamaki was rendered speechless the entire time, communicating his immense pleasure through moans, groans, and gasps.

Tamaki: (Mirio is incredible!)

Tamaki's precum appeared on the tip of his dick, making Mirio want to send him over the ledge.

After Tamaki's hole was loose and filled with lube, Mirio pulled his fingers out of his ass.

Tamaki: "W-what's wrong?"

Mirio: "It's time for the main course~"

Mirio pulled down his pants and underwear before towering over Tamaki.

Tamaki blushed and knew what to expect from Mirio's monster cock.

Mirio cautiously slid his dick inside of Tamaki and groaned as their bodies collided.

Mirio: "O-ooh~"

Mirio began moving in and out, forcing Tamaki to let out numerous moans that varied in volume.

Mirio: "Ngh~ s-so... good~!"

Tamaki: "A-agh, yes~!"

Tamaki's cum flowed out of his dick, shortly before Mirio pulls out and squirts his cum on the sheets.

Remnants of Tamaki's cum trickle down his dick and stain the bedsheets.

Mirio: *chuckles nervously* "S-sorry."

Tamaki: *sighs* "It's ok."
