Sylvia was helpless as the watery tentacle continued to thrust into her, Mareth's various chemicals causing her to reach climax again and again.  After the first three, she was barely able to move or support her own weight, laying helpless to the nymph's attentions.<br/><br/>Her sleeping form was likewise laying weakly, unable to offer any resistance as Mareth's tail continued to violate her.  When the succubus reached her own climax, filling Sylvia with her fluids, the symbols drawn on her body began to flare brightly.  Another symbol, a black mark in the shape of a stylized heart with three points extending from it, began to form on her belly just above her sex.  A few moments later however, most of the symbol faded away, leaving only one corner of the heart and one of the points visible - a sign that, despite her weary state, Sylvia was still able to resist most of the succubus's corruption.  That symbol, too, faded away after a few moments, though it was only hidden - Mareth would be able to see it as plain as day, but to everyone else, it was hidden well enough that only strong magic could reveal it again.<br/><br/>As the ritual wound to a close, Sylvia's dream-world began to twist and warp as she slipped into a deeper sleep and the gemstone began to lose its power to keep her in the dream.
