Halcyon made a soft, pleasant little humming noise, now audible without the rainfall of the shower about them.  The sensation was no longer unpleasant, though Elke's sheer size made it impossible for the act to be entirely without pain.  As the Manlian started to thrust deep and hard in earnest, Halcyon started to push back, instinctively responding to the rhythm and matching it exactly.  As she was firmly and thoroughly used by the strange engineer, she cooed softly, a weird noise unlike most of the noises she made as a matter of course.<br/><br/>Relaxed and lubricated, she was still plenty tight, and her body started to respond with pleasure to the intimate experience.  Even as Elke quickened her thrusts, Halcyon matched her movements, moving with the seemingly instinctive sensuality that one would expect from a whore or a doxie, rather than a half-sane genius.  She had no expectation or need or desire to achieve greater pleasure for herself; it wasn't something she was capable of conceiving of.  As a result she responded by reacting to Elke's movements and that increased Elke's pleasure.  Not that it wasn't pleasurable.  Halcyon lowered her head and arms to pillow her head on them, thrusting her derriere higher and letting Elke master her as Elke had been used to being mastered on her homeworld.
