He loved the way her hands felt on him. He became so accustomed to her being held in his own hand in weapon form, it was always a pleasant surprise in the moments she was human with him. Her soul wavelength soothed his own immensely, helped him breathe easier and think more clearly.
On quiet nights, he had taken to coming beside her on the couch and eventually laying his head down on her legs while she read. The first time she had jumped so bad he'd been jerked right onto the floor, but now it was so routine she didn't glance up from her book. She just absently placed a hand in his white hair, softly pulling her fingers through the fine strands and gently massaging his scalp. She was careful around his screw, merely rubbing the spot it went through his head. His eyes would slip closed as his heart rate slowed. He wondered vaguely if this was what being peaceful felt like.
"Marie..." He'd utter softly after a time and she'd mark her place, setting her book to the side. Keeping one hand in his hair, she moved the other to his face, using two fingers to trace patterns over his skin. She gingerly brushed them over the scars. He'd let out a long, contented breath and wouldn't see her smile behind his closed eyelids.
She'd then lean and place her lips to his forehead, giving him a chaste kiss. She'd then do the same to each closed eye and he'd sigh softly again. Then finally came a loving, lingering kiss to his lips that he would return gratefully. Kissing her felt like nothing he could explain. What a wonderful mystery she was.
She would pull back after a few more seconds and his eyes would open to see her one golden eye and a smile on her face, just for him.
"Go to seep, Stein."
And, like a child held safely in his mother's arms, he would.
