In Eraser Head's classroom

Eraser Head was sat at his desk, going over his students' grades.

Eraser Head: "Let's see... Iida has a 100, Yaoyorozu a 93, Bakugo an 86, Kaminari a 51..."

Present Mic walks down the hall whilst whistling but stops to peek in the classroom and greet his black haired lover.

Present Mic: "Hey there, Shota!"

Eraser Head: *sighs* "Hey Mic."

Present Mic: "What'cha doing?"

Eraser Head: "Entering grades for my class."

Present Mic: "Sounds boring."

Eraser Head: "Well... that's kinda our job."

Present Mic suddenly sat on Eraser Head's lap and tossed the paperwork on the floor.

Eraser Head: *sighs* "What's your problem, Mic?"

Present Mic: "I'm feelin' a little frisky, if you know what I mean~"

Eraser Head: "Not right now, Hizashi-"

Eraser Head gasped as Present Mic kissed his neck. The black haired male blushed and dropped his paperwork as his blonde lover continued planting kisses on his neck and trailing down his chest.

Present Mic: "Mm~"

Eraser Head: "Z-Zashi~ hold on..."

Present Mic: (Seems like Shota's losing his cool.) 

Present Mic strips his Eraser Head of his shirt and begins sucking on his nipple while tweaking the other, forcing numerous groans to escape the black haired man's mouth.

Eraser Head: "A-aah~"

Present Mic: "Hah~"

Eraser Head's dick stiffened in his pants and he began pushing his paperwork off of his desk, causing Present Mic to stop teasing him.

Present Mic: "What are you doing?"

Eraser Head: "I'm about to fuck you, duh."

Present Mic gasped and a smile beamed on his face as he quickly hopped onto the desk and pulled his pants and underwear down.

Eraser Head slipped his finger in Present Mic's mouth before inserting it in the loud blonde's ass. 

Present Mic: *gasps* "Oh my God~!"

A devilish grin races across Eraser Head's face as he rhythmically slid his finger in and out of Present Mic's hole.

No matter how hard Present Mic tried to keep his voice down, numerous moans escaped his mouth.

Present Mic: "H-hah~ Sh-Sho~"

Eraser Head: (I gotta admit, seeing him like this is kinda cute...)

Eraser Head pulls his finger out of Present Mic's ass and pulls his own pants down, revealing his dick.

Eraser Head: *grins*

Present Mic: *gulps* 

Due to Present Mic's hole already being wet, the black-haired male was able to slide his cock in with ease, forcing a grunt out of the blonde.

Present Mic: "G-grr~"

Eraser Head: "Heh..."

Eraser Head began thrusting in and out slowly as the pleasure in Present Mic's voice became more and more apparent.

Present Mic: "Oh yes~ Oh god yes, Shota~!"

Eraser Head: (Sexy...)

Eraser Head gradually sped up and Present Mic's breathing became hitched as he moaned and gasped.

Present Mic: (His dick feels so fucking amazing inside me!!)

Eraser Head: "Z-Zashi~ I'm close!"

Eraser Head grunts as he cums inside of Present Mic's ass. The blonde moans as he squirts onto his lover's desk.

Present Mic: *sighs* "That... was awesome!"

Eraser Head: *smirks* "Guess I won't be grading any more papers tonight."
