Summary
Alex has always made it a point to mind his own business. He wakes up, works out, heads to the beach, or helps out around the house, then goes to bed. Rinse and repeat, adding the occasional two-hour phone call from Haley updating him on her summer in Zuzu City. If anyone asks, he won’t be here for much longer, onto bigger and better things, like earning a spot on a professional gridball team.
Sebastian isn’t one to open up to people. He has Sam and Abigail, and that’s more than enough for him, seeing as he won’t be in Pelican Town by this time next year. Or, that’s what he tells himself each time someone interrupts his work or makes band practice run later than it needs to. He’s alone, happy, and has no plans to change that.
Until the night Alex catches sight of a light coming from inside the abandoned Community Center, and Sebastian is just crossed enough to let his mind run away with itself.

Summary
It was Sebastian Romano's birthday and the only thing that he really wants from his husband, Gabriel Castillo, for his birthday is to top him for once. And he gets that, but they didn't use any protection. And since Gabriel was always the top in any relationship he never got tested for being a carrier. So what happens now that they have a little surprise on the way?
This is loosely based off the low budget film "Paternity Leave."

#9 Skirt Stays On by sinsoftheabyss (horrorsintheunknown)

Summary
Sebastian couldn’t breathe, his head spun wildly as he hugged the bedpost tightly for support. Not that he needed breath, but the feeling of his lungs being squeezed to the point of popping was deeply unpleasant.
“Okay, okay! I’ll never make you wear a corset again! Can you drop it?!”
Ciel let go of the lace immediately and Sebastian felt an immediate relief as his torso expanded just enough to be comfortable again. His eyes brightened, “Really?”
Sebastian gritted his teeth, “Bastard…”

#8 Knife/Gun Play by sinsoftheabyss (horrorsintheunknown)
Fandoms: Kuroshitsuji | Black Butler

Tags
Summary
The dagger left his chin, trailing downwards until it met his shirt collar. Ciel teased the fabric with the blade for a moment before making a quick slice down Sebastian’s chest down to his abdomen. It wasn’t particularly forceful, but the sharpness of the blade did the work for him.
Sebastian looked down to see his skin torn open, blood running down his torso as the cut already started to heal itself.
“Does this hurt?” Ciel asked as he ran his hand over the wound, digging in his fingernails to stop it from healing.
Sebastian’s breath stuttered as Ciel prodded inside, “Yes.”

Summary
“My Lord… I think there's a mistake here.”
“What do you mean?” Ciel asked in response, but that didn't stop him from stripping the man of his pants.
What was he even supposed to say? That this wasn't what he meant? That he, his Lord, couldn't do as he pleased?
No, no and no.
There was no way that was going to happen!----
Sebastian finds out that his young Master wanders into lustful desires and offers his help to satisfy him, but things gets a turn he didn't expect. -

Summary
“Permission to speak, my lord.”
Ciel looked down, drinking in the sight of his butler kneeling under the desk, a red collar tightly clasped around his neck which was connected to a leash. Sebastian’s shirt and jacket had been discarded in the bedroom well before they arrived at the office.
“You may,” Ciel said lazily as he hoisted a foot onto Sebastian’s shoulder, digging his heel downward.

Mr. Sutcliff? by grellsutcliffno1fan for Insertpoetryhere
Fandoms: Kuroshitsuji | Black Butler

Tags
Summary
“Your coworkers have begun calling me, ‘Mr. Sutcliff’.”
“Have they now?”
“Tell them to stop.”
Grelle laughed, like the ringing of a bell, a gloved hand placed demurely over her painted lips. “Oh, come now. It’s far too entertaining for that.” She cocks an eyebrow, and it’s an expression, when worn by Grelle Sutcliff, that he has come to dread, “Why, does it make you feel emasculated, Bassy? Would you prefer I take Michaelis, then, when we get married?”Sebastian chokes, “When?”
—
Or: Grelle's coworkers have begun calling Sebastian 'Mr. Sutcliff". They fuck about it.
Or: Or: Grelle gets to use her princess stick :)
