"Astrid stop! GAH-!" Hiccup batted Astrids hands away from his face, her hands were covered in red paint and was trying to apply it to Hiccup's face she stopped and said "Hello Stoick." Hiccup turned around to see no one there and as he turned around he felt a wet hand connect with the side of his face he turned the rest of the way to see Astrid laughing her face off he pushed her away and grabbed his Gronckle Iron Sheild and looked in it's reflection, halfway across his face was a giant had print in red paint, he turned and glared at the woman and said "you are in for it now."
Three days later...
Astrid sat down and looked at hiccup as he searched for the blue paint Astrid usually uses "Ah-ha! there it is I knew I had left it around somewhere!" he turned and gave it to her, he had already painted himself with his own hand print since his father had commented on how good it looked on him "there you go milady!" he watched as she applied it to her skin and noticed some had got on her lips and grinned, Astrid noticed his grin and asked "What?" He started to laughed and stand up and say "does it taste a bit salty?" noticing her confused expression he pointed to his lip and she lapped up the paint with her tounge and thought yeah it does taste salty a lot like his- "Hiccup you discusting perv!" he laughed and ran away laughing and shouting "well you did say you wanted to be painted with it!"
After that Astrid kept her paint well away from Hiccup.
I got the idea from American Pie: Band Camp and thought i would be a good form of revenge for Hiccup
P.S. I am seriously just thinking of random thing and i know i could do better. sorry ;)
