Summary
Every night you dream of the same impossible shoreline, and every night he’s there waiting, his face hidden, his voice unmistakably Senku. In a world where the stars are beneath the waves and the music has no source, the two of you race, argue, and hold on a little longer than logic requires. You’ve spent years trying to find each other in the waking world and failing. But in the dream, at least, he always catches you.

Summary
She asked him to take her virginity as a science project. He agreed. Neither of them expected to fall in love.
Senku Ishigami doesn't do romance. But when his tutoring student shows up with a proposition too logical to refuse, he can't help but treat it like any other experiment: hypothesis, methodology, observation logs. The only problem? Experiments don't account for feelings. And somewhere between the late-night study sessions and the rain-soaked car rides, the data stops adding up.
Now the experiment has spiraled into something neither of them can control. The only variable left to solve is the equation of us.

Summary
You’re on thin ice with your boss because of Abby and Jinu’s one night stands that they get caught up with.
“Why don’t you take their place.”
As if you would, to hell with them.. right? Wrong, it may have seemed like they were giving you a choice but it was either you let them fuck you or they get caught fucking around again and get you fired.
You liked your job better than the old ones so your job has to stay, but before you give in to them you need to go for the one you’ve been crushing on, Romance.

Summary
Chigiri can’t help it if his hands finally leave their place pinned above his head, sinking deep into your hair to hold you in place with a garbled sound that was half shriek, half whimper, “Fuck, f u c k —!”
And then you stop, pulling his cock out of your mouth with an obscene sound and a smirk that promises no reward for his disobedience.
“ah, ah, where did I say to put your hands, princess?”
OR: "Don't forget — who wanted who first?" You hiss up at him.

Summary
Your foot nudges his shin under the table. He barely notices at first, still scribbling messy formulas, mumbling about orbital mechanics. But then you stretch your leg further, sliding your socked toes up the denim of his jeans, pressing higher until—
“—what are you—” His pen stills. His voice cuts short when your toes press against the growing bulge in his lap.
Satoru blinks at you from over his laptop, blue eyes wide behind his crooked glasses. His mouth opens like he’s about to protest, but nothing comes out—just a strangled little inhale.
You smirk, tilting your head as you pretend to go back to your notes. “Keep talking, genius. Something about atmospheric drag?”
You and your astrophysics major boyfriend go to a coffee shop to do some work when you get the brilliant idea to play with him—watching him stammer and ramble about orbital decay and whatever else with your foot pressed to his cock under the table.
