Halcyon made a strange, chirruping noise deep in her throat as she was repositioned.  Her hands pressed against the wall for support - and thus protecting Elke from accidental electrocution if she climaxed again, as her hands had ceased emitting electrical charges - she pushed back into the quick, deep thrusts.  The dark haired head came up and she yelped as hot liquid poured inside her body and was pushed out, forced by the lack of space in her body to ooze slowly from the edges of her burning slit.<br/><br/>She glanced sidelong back at Elke, no reproach in her gaze, panting softly.  She reached between her legs and slowly felt the join of her sex and Elke's sex, exploring the sensitive flesh of herself and of her lover.  Glancing back again, she moved her hand from underneath her body to her back and slid it along her heart shaped derriere....and then gently used two fingers and pulled at the other opening.<br/><br/>It was not desire or lust; those were emotions she couldn't quantify in terms of herself or others.  It was curiosity; what felt good in one place might or might not feel good in another.  The biological functions as she had experienced them were similar in effect if not in results; there was a measure of pleasure involved in two of the three biological functions.  The third was just irritating and messy, and made the computers argumentative.
