"Where are we going Doctor?" Whinned Peri, followed by
"What's happening to me?" In a small frightened voice so unlike her normal
tones that he was forced to stop and turn to her,  taking her in his arms as
if to comfort a small child.
"I don't know what's happening anymore, but I do know where it started, and
that's where we're going, Zitmus.  I should have taken you there before, but
whatever it is has started to affect me too."
As he spoke the Doctor began to stroke Peri's hair, he had never before
realised just how soft and thick it was.  He became aware of Peri's hands
slowly massaging his back, then cirling lower to cup his buttocks.  he knew
he shuld stop this, but the gentle ministrations of Peri's hands was almost
mesmerising.  He allowed his own hands to roam lower, running down her back,
moving to gently sqeeze her ass.  All their hearts bean to pound, the Doctor
becoming excited inspite of himself, Peri yearning to have the gapoing need
within her filled with the Doctor's lust.
The Doctor leaned down, lifting Peri off her feet with that deceptive
strength he occasionally displayed.  He bent to kiss her, tenderly at first,
then deeper, almost fevoursly, mapping every secret corner of her mouth with
his tongue. She responded
in kind, exploring with such passion that the kiss became a battle, each
vying for the upper hand.  Peri's hands continued their actions, now
slipping inside his coat, nimbly darting down the waistband of his trousers,
still squeezing and massaging his arse.  She could feel his errection
against her thigh, the heat of it sending a fiery glow to her own, already
inflammed centre.  Suddenly she moved her right hand forward, grasping the
throbing length, and running her hand from base to tip, rolling her thumb
around the head, then returning to run her hand lightly over his balls.  The
Doctor gasped with surprise, and pleasure, stumbling forward, landing Peri
jammed against the console, his manhood rammed against her.  This time she
gasped in excitment, quickly unlipping his braces and pushing his trousers
down, her hands against his thighs sending waves of pleasure through him. He
disgarded the blanket Peri had wrapped around her shoulders, running his
thumbs around her already hard nipples, then bending forward to take one
between his teeth, pulling and teasing.  She moaned, raking her finger nails
down his back, leaving red trails of dark blood, welling up and running down
his shirt, marking in with spreading, almost black stains.  He growled, and
responded in kind, nipping at her breasts, pinpricks
of bright red rising here and there.  Her hands moved forward, passing
briefly over his hard nubs, before ripping his shirt in two, the two halves
fluttering to the floor, instantly forgotten by both parties.
The Doctor swept his hands round, enjoying feeling her curvasous body under
him.
He pushed his finger into her, then another, flicking her swollen clit.  The
heat withinhg er was like fire, her core felt like like molten lava.  She
moaned in response, sinking her teeth into his shoulder.  The pain
intensified his actions, he withdrew his
fingers and instead rammed his throbbing dick into her, gripping her back
and pulling her against himself.  He grunted as pleasure and pain mingled in
the catophany of sensations washing over him, he began to thrust with a
violent energy, her hands gripping his
buttocks, impaling herself, wanting him deeper within her, deeper even than
his eigt inches would allow.  He buried himself to the hilt, his balls
slapping against her ass.  He moved his hands under her, exploring her
asshole, nearly lifting her off the console, thrusting his fingers deep in
time with his cock.
They were both lost now, any shred of coherent thought within them scattered
by lust and the energy of Zitmus.
The Doctor thrust one final time,m as his passion errupted, and his burning
seed shot deep inside her, her muscles contracting to milk every last d at it as the 
Doctor had done such a short time ago.  Her left hanf began to move
faster, flicking in and out of her soaking pussy.
	The Doctor watched, fasinated, his cock rising in his slacks.
Unconsciously  his hand moved to stroke it, long slow movements that
picked up in pace to match the hightened intensity of Peri's actions.
	Peri's frenzy increased, she moaned in frustration at her
inability to satisfy herself.  She longed more than anything else for
release, but it seemed to constantly elude her.  She pulled and bit at 
her tits, running her nails down her thighs, watching mesmerised as thin
tracks of blood followed them.  She rubbed furiously at her clit, pushing
four fingers into her pussy, her hips bucking in him, moving at a speed
that seemed almost impossible to the Doctor, who continued to pump his
own member, leaning back against the console, pushing his waistband down
to allow himself full access. 
"Doctor...." Peri moaned, longing to feel his cock thrusting into her, wanting to feel his nails raking over her body, his teeth pulling at her nipples.

The Doctor's head jerked in surprise: Had she really called his name?
 
"Doctor... please.... I need you......"
This name there was no mistaking it.  The sound of Peri's voice calling his name hightened his passions, and with a deep groan he came, his cum spurting out across the console room.  He sagged, spent, enjoying the release.  Once again however, Peri enjoyed no such pleasure.  She continued to rub her clit, working her cunt with feverous intent.  
"Doctor, oh Doctor" she moaned over and over, in time with her animal thrusts.
The Doctor froze, agonised.  To help her may send himself over the edge, drive him to a condition as out of control as hers, while driving her deeper into her frenzy.  Yet what damage could be done if she remained in this state?  What hightened level of sexual activity could give her peace long enough for him to find a solution, to rid her of this desire?
He reached a descision, and strode purposfully towards her room.
