Title: Round 2
Natsu Dragneel and Erza Scarlet wearing the outfits from the Stone Age Omake.
Natsu won't have the jacket on and Erza will only have the loincloth portion of her outfit on.
One Panel - with the point of view facing the two characters from the side.
Standing Face-to-Face with Erza leaning back against a tree/rock, one hand raised up bracing against the tree/rock and the other, gripping one of the ends of Natsu's scarf to hold, pull his head closer to hers. Her legs are spread enough with one leg held up with Natsu's arm hooked around it.
Natsu has one arm hooked around her raised leg and the other hand on her hip to pull her against his thrusts.
Both are looking at each other, Erza's eyes are half-lidded, while Natsu's slightly more open. Their mouths are open with a thin trail of saliva between both of their tongues.
Bonus: Image of a comedic Lucy with huge eyes and a blush on spying on them from behind a far off tree.
