How does Stoker use language to describe Lucy's appearance when she return to her tomb?

The death scene of the vampire Lucy resonates with overtones of penetration and sexuality. Until this moment, Lucy has only been penetrated by Dracula‹the staking is, in a way, her fiancé's first chance at his nuptial rights. Note that Arthur does the deed, even though it might make more sense for a more detached man to drive home the stake. As with Lucy's description of her out-of-body experience, the imagery of the phallus, penetration, and the orgasm are the three dominant shapers of the scene. Arthur plunges his stake into Lucy's body, driving deeper and deeper with a ferocity that surprises the other men, while the vampire Lucy screams and quivers. Seward records that the body "Shook and quivered and twisted in wild contortions," and afterward Arthur is exhausted from the effort.
