very kissable by brainrotprofessional

Summary
“Uh.” Mark halts. “Did I... hurt you?” He lowers the razor safely off Simon’s skin.
The warm hand at his waist tightens. Squeezes. Mark is unceremoniously tugged forward until his lower half is as close to Simon as his upper half.
His thighs meet the cold metal of the sink counter, but the feeling doesn’t even register to Mark who is, currently, going through a full mental system reboot.
“No,” Simon says, and swallows. It looks heavy, makes his freshly shaven skin bob. His voice is rough when he says, “Wanted you closer.”
Mark’s pretty sure he makes a very stupid face just then. Because. What?
“Oh,” he whispers faintly.
—
Mark, Simon, and the intimacy of trusting someone despite it all. Apparently, mundane things become a big deal when you’re in love.

Summary
Clark smiles. The curl of his lips brushes down and across Bruce's throat; Bruce swallows against the urge to tilt his head for ease of access, instincts screaming at him to never show his belly. To guard his softest, weakest parts with his life.
He’s still learning— the fact that he doesn’t have to prepare for devastation when Clark touches him.
Bruce fists the sheets, forces himself still. Another kiss to the side of his throat, then a meandering path downwards, to the slope of his pale shoulder, back inwards towards his spine.
At the topmost knob, another kiss, reverent and worshipful. Bruce sighs into it, eyes fluttering shut.
—
A sleepy, warm morning between Clark and Bruce, complete with many indulgent kisses and heaping handfuls of tenderness.

Summary
Gender expression for Izuku is… hard. To say the least.
When it comes down to it, he really doesn’t care much about the clothes he wears, but sometimes he can’t help the vague feeling of wrongness that fills his chest when he looks at his outfit in the mirror.
After sufficient research, he realizes he needs help from the resident fashion experts of Class 1-A.
—Whilst exploring gender expression, Izuku asks for Mina's help. She's supportive, of course, in perhaps more ways than Izuku bargained for.

Summary
The ring has been burning a hole through Katsuki’s pocket the entire night. The box it’s in is plain black and smooth, unassuming. Yet, every time his fingers brush over it, his heart thuds that bit harder. For some reason, this feels like a big thing. Maybe it’s because it’s a ring, but it’s not like Katsuki’s proposing. It’s a Christmas gift for his boyfriend, there’s no reason for him to be so nervous.
And yet.
—
While deliberating what gift to give Izuku, Katsuki stumbles across a promise ring, and immediately knows what he has to do.

Summary
“Do you really have to sit on my lap?”
Izuku tucks his legs in, making himself as small as possible to fit in the cradle of Kacchan’s chest. It isn’t very easy, since Izuku’s built up so much muscle mass, but Kacchan’s broad. He makes it work.
“Kacchan’s warm,” Izuku responds, finally settling down with a sigh.
“I’m killing you when this shit wears off,” Kacchan promises.
—
Izuku is hit with a villain’s quirk that forces him and Katsuki to be in close-quarters at all times.
(It goes a lot better than you’d expect.)

“Hey there,” Grace attempts.
“Ry?”
Or, Colt and Grace are estranged twins who begin to have very strange shared dreams.

Summary
There would be no salvation for him. He was going to die. For one unexpected, peaceful moment, Simon was weightless. Everything fell silent. No more panic, no more pain, no more terror. He didn’t have to fight anymore.
Just as consciousness slipped from his grasp, the sound of static broke the silence. The radio crackled to life.
