"Something on my face?" Cross asked, and his chuckle sounded a bit strained this time.
Nightmare didn't answer for a second. His tentacles were no longer idle, instead flicking minutely, coiling their tips into themselves. "No," he said finally, "I just thought we could have some fun together."

“D-do you r-really think-k-k-k-k -” There’s a clicking sound as Error crashes, though he’s back up so quickly that Nightmare barely registers the REBOOTING bar above his head. “Who th-the fuck l-laughed a-at you?!”
“No one who’s still alive,” Nightmare assures him bitterly.

Red was a heavy sleeper. This Sans knew very well. And it just wouldn’t do to not take that to his advantage.

Summary
"Error, what did you do?"
Ink didn't expect there to be AUs beyond the Doodle Sphere. Core Frisk never would have thought that there are things they can never see. Error never thought he would get his ass kicked by a bunch of humans.
The Spider Society should probably have planned first contact a bit more.

Summary
After a heated workout, Killer puts some juicy and thought provoking ideas in the horny Cross’ head. Right as their mate Nightmare (who has his female Ecto body on display) is working it in the gym.
Needless to say, Cross can't wait until night falls to see if Killer words are true. Because it's his turn to sleep with his king.Bookmarked by A_Sad_Unity
