Lure of the Sirens: A Sci Fi Choose Your Own Erotic Story

by Callista Hawkes

  “It’s so big.” She gasps, her eyes watering slightly. You know this is

  pure theatre on Vanessa’s part, designed to fit the character as she does not

  possess a gag reflex and has deep-throated you on numerous occasions in

  the past, but you are more than willing to play along.

  “Use your hand as well as your mouth.” You suggest. She nods and

  reaches up, wrapping her fingers around your shaft and taking you back

  between her lips. Growing in confidence, she begins to rock her head back

  and forth, her lips slurping up and down the end of your cock while her hand

  pumps your shaft. A moan escapes your lips and you gaze down at this

  beautiful but shy brunette version of Vanessa pleasuring you. Her hazel eyes

  gaze up at you and it really does seem like another woman with her

  contrasting personality and performance as well as the physical differences

  of her dark hair and smaller pert breasts. The thought only amplifies your

  exhilaration and you can feel your balls tighten before you let out a long

  groan of release as your semen rushes up your shaft to erupt into her

  sucking mouth. Her eyes widen in surprise, but she pulls back slightly and

  locks her lips around the bulbous head as it twitches again and again,

  sending a torrent of hot come into her waiting mouth. You grunt with each

  powerful pulse until your climax ebbs and you take an unsteady step

  backwards, your cock slipping from her lips. Her eyes fixed on yours, she

  gulps down your come.

  “Was that satisfactory captain?” She smiles shyly.

  “I would have thought the evidence you just swallowed would speak

  for itself.” You quip. “Did you like doing that?”

  “I did.” She admits quietly, her eyes dropping to the floor. “I’d like to

  do it again.”

  “I’d like that too.” You smile. “But right now we’d better get

  underway.” She nods and gets to her feet, stooping and retrieving her catsuit. As she pulls it on, her hair lengthens, returning to its usual coppery red while her breasts expand to their previous size. In a moment, the

  demure brunette has disappeared to be replaced by the familiar, confident

  redheaded Vanessa.

  “You seemed to enjoy that character.” She comments with a wry

  smile, her hand on her hip. “I’ll have to remember her.”

  “Please do.” You grin before your smile fades as you remember the

  time sensitive job you are tasked with. “We’d better load the cargo and get

  space bound.”

  “As you wish captain.” Vanessa meekly replies, lowering her eyes

  shyly. She then looks up, her green eyes gleaming, a wicked smile on her

  face before turning and disappearing through the door.

  “Nice new look, but time is a factor with this shipment.” You tell Vanessa, sitting down in your chair. “We’d better get the cargo loaded.”

  Vanessa’s eyes widen in surprise and her hair begins to lengthen,

  returning to its previous coppery red hue. Her breasts swell beyond their

  previous size until they stretch the material of her silver catsuit. She pulls

  down the zip a few more inches revealing her magnificent cleavage.

  “You sure about that?” She asks, raising an eyebrow.

  Give in to your baser instincts

  She might have a great cleavage, but she’s still a machine!

  “Well, I suppose we do have a little time.” You reply. Her lips curl into a smile and she moves towards you, sitting astride you. She leans forward,

  pressing her lips to yours and kissing you passionately. You can feel a

  tightening in your groin as your cock begins to harden. She pulls back, her

  eyes fixed on yours, pouting slightly as she tugs at the zip of her catsuit, her full breasts revealed to you tantalisingly slowly. As she opens the zip to her

  waist, the silver fabric falls open and you feel a smile cross your face as her breasts are fully exposed. Vanessa has inflated them to their maximum size

  and you eagerly take them in your hands, caressing them and teasing her

  nipples. Vanessa groans in pleasure, her hands going to the back of your

  head and guiding your face to her heaving breasts. You take a nipple into

  your mouth, gently sucking on it. Vanessa throws her head back, a

  contented moan escaping her lips before she guides your head to her other

  breast where you repeat the process.

  “You always do like the double dees don’t you?” She breathes as you

  lavish attention upon them.

  “Mmmm hmmm.” You reply, your lips still pressed to her right nipple.

  You pull back and she presses her lips to yours, kissing you passionately,

  while her hand caresses the growing bulge between your legs.

  “And to think you were playing hard to get.” She murmurs seductively.

  “What would you like to do next?”

  Bend her over the control console and enter her from behind

  Have her suck your cock

  Without a word, you get to your feet and take her in your arms, pressing your lips hungrily to hers. She responds in kind, kissing you

  passionately. You slide your hands up her back before pulling her catsuit off

  her shoulders and yanking it down. Vanessa gasps into your mouth as the

  garment slides down her body leaving her naked before you. Her hands

  reach for your waist, unbuckling your belt and unfastening your trousers.

  She tugs down your trousers and underpants as one, your holstered blaster

  hitting the deck plate with a thud. Her fingers move to your chest and

  quickly unbutton your shirt. You throw it off, groaning as her hand slides

  down and tightens around your hardening cock. You turn her to face away

  from you and guide her towards the control console. You gently ease her

  forward and she guesses your intentions, bending forward and supporting

  herself on the flat glossy glass surface of the console. She parts her legs and glances over her shoulder at you, a lustful gleam in her eye.

  “Do it.” She breathes. “Fill me with your cock.” You are only too happy

  to oblige and guide the straining head of your erect shaft to the dewy lips of

  her pussy. You groan in unison as you slide your length inside her. You grasp

  her hips for purchase and begin to thrust into her.

  “Yes, yes!” She moans. “Harder! Fuck me harder!” You ram your cock

  into her, her body rocking forward with each thrust. Her hands slide over the

  smooth surface of the console, trying to keep herself supported as you

  vigorously plough into her. She thrusts her hips back onto you, your cock

  slamming into her right up to the hilt. You lean forward, reaching around to

  caress her pendulous breasts which are swinging in time with your thrusts.

  She groans as you squeeze the large fleshy mounds, your thumbs flicking

  over her nipples. You slide your hands down her sides, one gripping her hip

  while the other slides between her legs seeking her clit. Vanessa gasps as

  you find it, teasing the little nub with a fingertip as you continue to pound

  into her. Your mind fights its customary battle as you remember that

  Vanessa is just an android, a machine, while another lustful part argues that

  she certainly doesn’t look, feel or act like an android. Furthermore, her A.I.

  learns what you like, so she knows exactly what to do and when to do it to

  give you the maximum pleasure. Your thoughts a
re interrupted by loud

  cheering outside. You glance up through the cockpit window noticing that a

  group of dockhands have assembled in front of the Eclipse and are clearly

  enjoying the view. Vanessa giggles and straightens her arms, stretching

  upwards and displaying her magnificent breasts to your audience. The watching dockhands holler their approval and Vanessa’s cries of pleasure go

  up a notch. It might just be her programming, but she evidently enjoys an

  audience.

  “You dirty bitch.” You chuckle into her ear. “I never knew you liked to

  be watched.”

  “Well now you do.” She pants. “Now shut up and fuck me. I’m really

  close.”

  You continue to rub her clit while pumping your thick cock inside her

  and sure enough, moments later she stiffens and with a cry of pure ecstasy,

  she reaches her orgasm, trembling as she comes. You keep your cock buried

  deep inside her as her body convulses around your throbbing length.

  “That was fantastic.” She finally gasps, sliding off you, turning and

  pressing her lips to yours. Your bodies, both moist with perspiration, are

  pressed together, her large breasts crushed against your heaving chest as

  you catch your breath.

  “You want to give our audience a curtain call?” You suggest.

  “Why not.” Vanessa purrs. “What did you have in mind?”

  Lie on the console and have her ride you

  Have her lie back on the console and guide your cock to her magnificent

  cleavage

  You lie on your back on the console, the glass surface cold against your skin and gesture for Vanessa to sit astride you. As she climbs on top of you,

  the console creaking from your combined weight, it crosses your mind that

  the manufacturers of this instrument panel probably didn’t have the weight

  of two amorous lovers in mind when they designed it. Vanessa smiles down

  at you as she reaches for your cock and guides it to her sopping hole. Her

  mouth drops open and her eyes close as she sinks down on you, your cock

  sliding easily back inside her. She begins to ride you, bouncing up and down

  and grinding her hips against you. You reach up and caress her breasts,

  teasing her nipples. You glance up to see her reaction and find that her

  attention is elsewhere, smiling out of the cockpit window at the watching

  dockhands. You pinch her nipples, bringing her attention back to you.

  Vanessa shrugs apologetically and begins to ride you in earnest. You can feel

  a stirring in your balls as the pressure begins to build. Vanessa senses it

  (Perhaps literally) and reaches behind her. You groan as you feel her fingers

  play over your tight ball sack. You glance out of the cockpit window, the

  dockhands egging Vanessa on as she continues to ride you with wild

  abandon. You look back up at Vanessa, her green eyes studying you, a

  wicked grin crossing her face as her fingers caress your sensitive ball sack.

  “Vanessa...” You gasp, knowing what’s next. The rest of the sentence

  is lost in a long drawn out grunt of pleasure as you feel her pussy begin to

  vibrate around your throbbing cock. With a final thrust up inside her, you

  stiffen and gasp as you feel your come race up your shaft to explode deep

  within her clenching, vibrating pussy. You grit your teeth as your whole body

  convulses beneath her, your cock pulsing powerfully again and again,

  blasting your thick creamy seed inside her. Finally, utterly spent, you relax,

  grinning contentedly up at the beautiful redhead. Outside, the dockhands

  are cheering and clapping until with the show over, they wander off to

  continue their duties. Vanessa climbs off you, your wilting cock hitting your

  stomach with a wet slap.

  “I feel better for that.” She grins, pulling her catsuit back on.

  “You and me both.” You smile, climbing wearily off the console.

  “I guess I’d better go and see about getting the cargo on board.”

  Vanessa tells you.

  “I’ll bet the dockhands will be falling over themselves to help you.”

  You grin, reaching for your own clothes. Vanessa laughs and heads for the

  door.

  Continue

  “Lie on your back.” You tell Vanessa. She nods and obeys, climbing onto the glass surface of the control console and parting her legs in

  anticipation. You smile, enjoying her surprise as your climb on, throwing a

  leg over her and sitting astride her chest. Vanessa giggles and guessing your

  intentions, cups her beautiful breasts as you guide your rigid shaft between

  them.

  “Who’s the dirty one now?” She grins up at you, pressing her breasts

  together and enveloping your cock between the large fleshy mounds. You

  flash her a smile in response as your begin to thrust through her soft, warm

  cleavage. Vanessa glances sideways through the cockpit window where the

  dockhands are still watching, grinning broadly at the impromptu show. A

  groan escapes your lips, enjoying the spectacle yourself as your throbbing

  cock slides through her magnificent cleavage. You moan, feeling a delicious

  sensation in your balls as you build towards your climax.

  “You’re getting close aren’t you?” Vanessa whispers. “I want you to

  shower me with your hot come. I want to feel it splash all over my big tits,”

  She squeezes her breasts and teases her nipples between thumb and

  forefinger, “and feel it dripping into my cleavage. How about it captain? You

  ready to give me a pearl necklace?” Her dirty talk has the desired effect and

  you feel your balls twitch as she sends you over the edge. You pull your cock

  free of her cleavage and stroke it, aiming it at her chest. With a roar of

  ecstasy, you explode, come streaking from the tip of your cock and

  splattering across her breasts. She grins up at you as you quickly coat her

  beautiful curves in your pearly seed, the creamy fluid dripping down and

  pooling in her cleavage.

  “Wow.” You gasp, gazing down at her defiled chest before climbing off

  her. Vanessa sits up on the console, flashes you a grin before turning to her

  adoring audience and presenting them with her come splattered breasts.

  You hear them whoop and cheer before there is a groan of disappointment

  as she turns her back to them and climbs down from the console.

  “I’d better get cleaned up.” She grins. “Then I’ll see about getting this

  cargo loaded.”

  “Something tells me that the dockhands will be falling over themselves

  to help you.” You grin, reaching for your clothes. Vanessa laughs, stooping to

  collect her catsuit and heads back to your quarters to freshen up.

  Continue

  “It would be nice to have a bit of peace and quiet around here.” You tell her. “Perhaps we can find another use for that overworked mouth of

  yours?” You raise an eyebrow. Her eyes open wide in surprise and just for a

  moment you wonder if you have genuinely offended her.

  “You’ll pay for that.” She tells you, her eyes narrowing before she

  drops to her knees on the deck in front of you. She quickly unbuckles your

  belt and tugs down your trousers and underpants before easing your legs

  apart. Your throbbing cock, finally freed from restraint, springs up in her face making her giggle.

  “Looks
like you’re ready for me.” She breathes huskily, taking your

  shaft in her hand and slowly stroking it. Her other hand reaches between

  your legs and massages your balls. Your eyes meet and she grins wickedly.

  You know what’s coming and sure enough, as her fingers play over your

  sensitive scrotum, the tips begin to vibrate. You let out a moan of pleasure

  at the added stimulation as her vibrating fingers caress your sack while her

  other hand continues to stroke you. She leans forward and guides your

  straining cock to her lips. You gasp as you feel the tip enveloped within the

  moist warmth of her mouth, her tongue working on the underside as she

  slides her lips down your length as far down as her pumping hand. Vanessa’s

  designers (understandably) hadn’t bothered to incorporate a gag reflex, so

  she slides her hand down to the root of your shaft and you watch as her lips

  slip all the way down your length. Your mouth drops open as you feel the

  blissful sensation of your cock buried deep in her throat. She begins to bob

  her head up and down on you, her vibrating fingers still teasing your balls.

  “That feels so good.” You groan, watching enthralled as her lips slide

  up and down your saliva soaked shaft. You can already feel the pressure

  building in your balls and you know you are moments away from spilling

  your seed into her waiting mouth.

  “I’m getting close.” You grunt. She immediately pulls back, your cock

  slipping free of her lips while her fingers on your balls cease to vibrate. You let out a groan of frustration, your cock desperate for stimulation, your balls aching with an urgent need for release. You look at her questioningly.

  “I told you you’d pay for your insolent remark.” She grins, slowly

  feathering kisses along your straining length.

  “Please Vanessa.” You beg, your balls aching with need. Her green

  eyes gleam as she enjoys the blissful agony she is inflicting on you.

  “These feel so full.” She teases, gently squeezing your tightened ballsack. “I bet you really need to come don’t you?” She licks the underside

  of your shaft from root to tip, making you strain forward, trying to guide the
