The color green
When his forehead presses against hers, his eyes are always at their brightest. Jellal's eyes are green like magic. They sparkle and glint in a way hers never do. She wants to be lost in them always.
The deep blue of their sheets brings out a fierce tint Erza rarely sees anywhere else. His eyes dig into her even deeper than the fingertips bruising her hips. They coat her skin with something tingly and exciting. When he sits up suddenly, they are wide open and she bites her lip. Jellal kisses her and she sighs.
She barely notices the air brushing over her skin until she is on her back. Her nails will leave a mark but his staccato exhales mean he likes it – wants it. Erza will not tolerate his self harm but she will give him the pain he seeks at her pleasure. His hands slide heavily along her arms and pin her wrists above her head. Her back arches greedily – selfish, greedy, lustfully...
Green.
Erza feels green. Her body sings and she wants to curl around him but he's too heavy. His weight keeps her beneath him and the way he takes is all she wants. She watches him until his eyelids flutter shut as he finishes.
If asked, Jellal says his favorite color is red. He loves to fill his hands and hide his face in everything scarlet. But she hopes when he looks inside of her he sees the imprint of green.
