What was she doing? She kept looking at him—or at least looking into the darkness where he watched, a pulsating shadow trying to control the urge to become solid so he could pleasure himself while watching her.
 
 Grace’s neck craned so that her head left the bed and stared into his peculiar abyss for a long moment before flopping back. Her hips swished and swiveled, pointing her sweet, soft womanhood at him, letting him have an unobstructed view of her fingers fiddling in her wetness.
 
 “Where’d you go, dream lover? You shouldn’t have left so soon,” Grace whimpered, fingers moving faster.
 
 Dream lover? Me?
 
 She’s calling for me?
 
 It was too tempting, and temptation could be used in his favor in one way or another. If he responded and Grace grew afraid, she’d leave. And he’d like that.
 
 Or she wouldn’t realize what was happening, and he’d get to play with his new toy. And he might like that even better.
 
 Gliding over, Nyx saw that her eyes were closed as she fucked herself with her fingers. His hand, warm with excitement, moved with a ghost-like featheriness over her arm. She didn’t open her eyes. Didn’t stop moving.
 
 His hand lightly rested on her wrist. Still no change in her motions—and now he could share them.
 
 Nyx shrank down small, a mere strip of black, like the slit between blinds. He was a mere stripe on her arm, her wrist, letting his most insubstantial form made of pure shadow feel the pull and push of her fingers as they plundered the juicy peach between her thighs.
 
 It wasn’t long before his heat took a more solid form—a band of pressure, pushing her fingers in deeper, harder, faster.
 
 She’s fucking herself, but I’m helping. Telling her fingers where to go. Reach deeper. Move faster. Pound harder.
 
 “Like that, like that. Almost there!”
 
 Nyx managed not to gasp audibly with an effort. It was like she was aware of the change of force but unaware of what caused it.
 
 “Please!” Her whispered wail almost undid him. He almost slipped, changed form, and gave her what she seemed to crave so badly.
 
 Instead, he vowed he’d relieve his urges later and take care of her first. His weight shifted, pushing her wrist in at a steeper angle, then resisted when she tried to withdraw. He trapped her fingers deep in her soft chasm, wishing he were the one to give her something hard.
 
 No, he thought.Stay there, let your walls have what they want, something to squeeze on, Sunflower.In his mind, he gave her a nickname. He moved his shadowy weight subtly, daring not just to rest on her hand, but to touch her—there.
 
 Nyx felt guilt burn him as he pulsed his dark, heavy energy against her hidden pearl of flesh, so slight that many men wouldhave overlooked it. He overlooked nothing. He was savoring every second of looking at her most secret pieces, and now touching them.
 
 I’m not hurting her. She wants this.
 
 But not from me.
 
 “Please, please, please...” Grace’s whimper absolved him, at least temporarily. Thick and fast, he rubbed her in circles while her thighs clamped down around her own hand. He heard her relieved moan and felt tremors course through her body before it went slack.
 
 “Oh, God.Yes.”
 
 Nyx fled the room, hurrying straight through wood, stone, and fabric down to the old bathroom at the end of the east wing. His body rippled and expanded until a tarry form greeted him in the mirror. Still thinking of her scent and her warmth, the sight of her dewy lips spread around two penetrating fingers, Nyx gripped his cock and came, releasing a smoky white mist that fell like vapor before rejoining his dark shape.
 
 What the hell have I done?
 
 And will she ever let me do it again?
