Credit for this idea goes to the Heroic Girl! (At least I think what you said was Thalia pissing Percy off. For some reason it wouldn't load the full suggestion. So if that isn't what you wanted, I'm sorry!)
The door banged open.
"Hey Annabeth. Someone told me you were in here and—"
Thalia's jaw dropped to the floor.
Annabeth and Percy both jumped apart in embarrassment, both glowing bright red in the face. She had just walked in on Percy and Annabeth kissing on his bed.
"Oh my gods," Thalia muttered, a hand over her eyes. "Couldn't you guys get a room? Eternal maiden over here."
"That's kind of why we were in here, Thalia," Percy snapped.
Annabeth adjusted her shirt, still bright red. "What was it that you wanted?"
"I was just going to tell you it was time for dinner," Thalia said. "But if you guys wanted something else, I could go tell Chiron and—"
"Shut up, Pinecone Face," Percy said, glowering at her. "Don't you have other things to do? Why don't you go hunt a bear or something."
"All in good time, Kelp Head," Thalia said, smiling wickedly. "If you guys aren't hungry, I'll just..."
She started to back out of the cabin, still grinning.
"No!" Annabeth practically shouted. "We're coming."
Annabeth hurried out of the room, leaving Thalia and Percy alone.
"Thalia, if you breathe a word of this to anyone..." Percy let the threat hang in the air.
Thalia held up her hands in defense. "Just as long as I don't see it again. You guys might want to find new places to do your thing, is all I'm saying."
With that, she turned on her heel and left the cabin. Percy stood there, stunned and mouth hanging open before he ran out the door after her.
"Oh my gods, Thalia! It wasn't like that!"
Just to let you know, they weren't doing it, if you know what I mean. Things may have gotten a little out of hand, though ;)
Again, apologies to Heroic Girl if this wasn't what you wanted. It was still fun to write though!
If you have a suggestion, leave it in the review or PM me! It can be whatever you want!
Thanks guys!
