You look about the room in some frustration, the panels the twins worked on were holographic and as insubstantial as air, so other than the nearest of the bio-tanks several meters away there is nothing to lean against. You certainly didn’t want to interrupt the tall Amazonian figures important work of designing you an army of cock-hungry alien super-sluts so you decide to make do.
You experimentally pinch the thin cloth of the taller twin’s sheer tight-fitting bodysuit between a massive finger and thumb. It stretches easily and despite being solid in color doesn’t feel any more substantial than nylon pantyhose and the realization makes you smile wickedly. You could work with this…
“Stand at attention with your thighs together, this doesn’t have to prevent you from doing your work if you are focused enough.” You murmur hotly in her ear as you quietly drop the small shorts you had been wearing to the cold metallic floor.
“I exceed at my role aboard this ship because I have excellent focus.” She replies coolly without any hint of pride or reproach in her clinically neutral voice, not a boast but a fact. She stands up straight, bringing her heels smartly together before resuming her endless work on the holographic computer displays as though you were no more distraction then an insect on her shoulder.
The change in her posture causes her ass to flex admirably under your powerful new hands and you roll your broad strong shoulders in anticipation as you position the head of your rigid aching great cock at the beginning of the small tight space between the tops of her thighs and the V of her pelvis where her legs meet her sex.
Her hands continue working smoothly over the projected controls as you slide the obscene length of your new and improved manhood up between her legs, across the outline of her pussy in the suits thin material until it emerges out from between her legs, jutting out in front of her like a lance. The sheer silken material of her garment feels almost frictionless as you pull back and, placing both hands on her slender muscled hips, you prepare for another long slow thrust.
You can feel the brunette twins thighs tightening around your aching dick as she tries to keep from having her legs forced apart by its unnatural girth and the lips of her pussy part slightly along the length of the shaft as it forces its way back along the narrow muscled corridor between her legs and pelvis. You hear her gasp softly as the huge mushroom head of it emerges out in front of her again and you gently slip a hand over her hip and down between her legs to stroke the nub of her clit through the stocking-thin material again.
“I… I don’t think…” the Amazonian figured twin begins to say as she shifts uncomfortably in your powerful grasp with an unfamiliar note of hesitance entering her usually cool voice, “I don’t think that this is – Oooh!”
Something about your finger on her clit or maybe her awkward shifting about with your cock straining up between her legs causes her to freeze mid sentence. Tilting her head, she frowns thoughtfully as she shifts her hips back a fraction towards your pelvis, the lips of her soft perfect pussy parting some more and sliding slowly back a little along the length of your iron-rigid pole. You hear her breath catch and feel her whole body tremble a little as she leans back against you before she finally regains her composure.
“Never mind, I misspoke. Proceed as before.” She states firmly and returns to her work on the displays in an unconvincing attempt at nonchalance. Her smaller copper-haired sister hasn’t stopped her secretive glances at the two of you and you smile at how arrogant and in control they are both trying to be, just like First had been….
Bending your knees and tensing your new muscles, far stronger, denser muscles than any to be found on earth, you thrust suddenly forward and upwards again into the silken smooth opening under her firm heart-shaped ass. The force of it raises the gorgeous alien on your cock onto her tiptoes as your inhumanly strong steely rod lifts her, the entrance to her pussy rubbing with the force of gravity and her own meager weight behind it against the length of your throbbing monstrous cock.
You feel her body tremble again as she leans back against your solid frame for support and a ragged breath escapes her lips but she doesn’t try to protest again. Instead she reaches a tentative hand down to the protruding mass of man meat poking out from between her thighs and touches it cautiously. You whole member tingles at the touch of her delicate soft hand.
“I do not think…” you hear the tall beautiful creature whisper breathily, “…I have given this aspect of human physiology close enough attention.”
Pulling your manhood back and lowering her to her feet again you reach around her slender athletic body to grab greedily at her firm C-cup breasts through the strange thin material and whisper fiercely into her ear.
“Well then, pay closer attention now!” You growl as you suddenly thrust your mighty hips forward, your cock taking all her weight and lifting her entirely off of her feet as it plunges through the silken opening sending a shudder of pleasure through your entire solidly muscled body.
The dark haired twin quivers in your formidable grasp, her newly built system of pleasure sensors and nerves bombarding her brain with unusual and unrestrained sensations of pleasure and delight. You can feel her nipples stiffen under the thin synthetic material of her tan bodysuit and you roll one tightening nip experimentally in your rough palm making her inhale sharply. Yes, her nanites were doing a fine job of building her new extensive nervous and pleasure systems…
The gorgeous alien in human form pants and wiggles pleasingly in your groping hold as you begin to rock your pelvis back and forth, sliding in and out of the tight grasp of her smooth muscular thighs and rubbing the pulsing shaft your thick rigid cock rock along the opening of her smooth twat. She wriggles her hips and squeezes her thighs together in a desperate need you are sure she doesn’t fully comprehend. She is fully aroused now, her sexually turbo-charged body wanting much more than this simple foreplay but her own vast clinical knowledge of human physiology doesn’t seem to extend to understanding how to satisfy this base carnal desire.
“Please… pleeeease…” she begs breathlessly, her short brown hair falling across her flushed face, “Please I need… I need…”
She doesn’t seem to know what she needs but you do.
“I know what you need.” You tell her with a wicked grin of satisfaction.
