It was the early morning of a dark night with a new moon. The sun had not yet rose and Meliodas and Elizabeth's room was almost pitch back except for one low burning candle near the door. Both of them were soundly asleep in their bed when it began. The shadows around Meliodas body slowly grew in size and solidified into an opaque form which then disappeared under the covers, leaving a tendril attached to its sleeping host.
Elizabeth sighed in her sleep as the darkness glided over her firm round breasts The darkness slowly made its way lower on her body stretching and continuing to caress her wonderful bosom. It rounded her hips and glided over her bountiful ass until it reached the edge of her thighs where it changed direction once again and slid beneath the thin white lace of her panties. The darkness caressed the soft blonde hair between her legs gently as not to wake her before it was ready. She moaned. It squeezed her ass slightly as it sent tendrils of shadow out across her soft skin, touching and caressing every inch of the sleeping girl. Finally, as it began to rub harder against her, Elizabeth woke.
"Mel..iodas-sama?" She moaned, a touch of fear in her quivering voice. 'He has never gone so far before,' she thought as her nipples were pinched "AH!'
Now that she was awake the darkness became more vigorous in its quest. It caressed the soft mound in between her legs and she shook at the pleasurable sensation. Elizabeth turned her head to Meliodas's sleeping form and was immediately terrified... There was no way he could be the one touching her! She opened her mouth to scream and as she inhaled a portion of the darkness entered her mouth. Other pieces wrapped her wrists and ankles binding her still. The covers had receded slightly due to the movements and she could now see what was pleasuring her. The darkness pulsed with a life of its own, purple streaks coming and going in its amorphous form.
'This..this is the same thing covering Meliodas after he broke free of the goddess amber,' she thought, realizing that it was in fact Meliodas (or part of Meliodas at least) that was touching her. Her fear lessened somewhat knowing that he would never hurt her, even unintentionally. It was as if the darkness sensed her relief. It began to further explore her soft cunt, softly rubbing her clit.
"mhmh...mmmmhm,"muffled by the darkness in her mouth Elizabeth moaned. She could feel the wetness of her arousal seeping from inside of her and filling her panties. It felt so so good. She strained against her bonds, causing the darkness to redouble its efforts and the rubbing became more vigorous. She attempted to cry out, but the darkness in her mouth prevented it, so she began to suck on it instead. It tasted strange but good, like wood smoke and...plum? It began to move in and out of her mouth, reaching further and further into her throat with each thrust.
The throbbing in her clit was unbearable. She couldn't take it anymore. Elizabeth screamed as she came, waves of pleasure rushed over every inch of her body. She shook as the orgasm ended and panted once the darkness removed itself from her mouth. It stoked he head tenderly and disappeared back into Meliodas's body. Exhausted, but satisfied Elizabeth drifted off into a dreamless sleep.
