Soo's eyes bobbed at Nell, a friendly expression. "Please, Crewmate Nell. Friend Nell. Become comfortable. Do not feel self conscious. We consider any suitable host to be, what you would consider, 'sexually attractive'."
Soo's eyes retreated again, but one after the other. Analogous to a wink, a cheeky smile. "Would you like help?" Soo waved its four tendrils in what might be considered seductive.
Nell felt acutely aware of herself. And was, in fact, feeling VERY self-conscious. "No!" she yelped, mostly out of embarrassment. "No, Soo, I uh I got it."
She gripped the hem of her uniform top and pulled it off, the tight fabric was stretchy and came off easily enough. There was little relief from the humid warmth of the room. Her pants came next, and she shimmied out of them. She peered down at herself, plain dark grey bra and undies, contrasting with her pale skin. She certainly hadn't planned on anyone besides herself seeing her naked. She rested her hands on her chubby belly, soft rolls released by the stretchy fabric. Her heart pounded in her throat. Soo gave an appreciative trill. "You look very healthy and suitable, Crewmate Nell, Friend Nell" Nell could feel the resonant tones Soo spoke with.
"Uhm thanks... I... you don't have to keep calling me crewmate. I know it's polite for you and all." Nell murmured, her face beet red.
Soo slithered over, eye stalks bobbing. They reached out a tendril arm, but hesitated before actually touching. Nell just nodded, looking away, avoiding eye contact, feeling awkward. She held back the urge to flinch as the cool, slimy tendril touched her bare belly, tracing gently around her bellybutton and down around the slight sag of her soft tummy. "Do not be nervous, Friend Nell. Before the invention of the surrogation devices, our hosts were often not willing. Stress hormones can damage our eggs and put the host's health in jeopardy, so we evolved to ensure this was a very pleasurable experience." A second tendril joined the first, leaving cooling slime trails across Nell's belly.
"Please relax, it will be best for both of us. Would you unclasp your undergarment?"
Nell nodded, reaching behind herself to undo the catch on her bra.
Soo rumbled, "May I touch you?" it asked.
Nell nodded again, then shivered at Soo's cool touch when their tendrils curled around the bands of the bra and pulled it away, returning to curl softly around her breasts. The slime Soo oozed seemed to increase in quantity, getting thicker. Not only did it feel cool but it began to tingle, exciting nerves wherever Soo touched. Each tendril curled around Nell's breasts several times, spiralling gently from chest to nipple. Nell couldn't suppress the soft moan that escaped her throat when Soo squeezed softly. Her nipples stiffening pleasurably as the whip-thin tips circled each, flicking and caressing the tender nubs. Soo, for its part, rumbled and cooed, some sounds far below Nell's hearing, some soft and just loud enough for her to hear. She felt the low rumbles travel through those tendrils, acting like personal vibrators for each breast. "Mmnh, Soo... lets uh... go lay down. You'll make my legs give out." Nell's voice was husky and thick, the embarrassment and awkwardness seeping away as the pleasure seeped in.
Her skin felt electric where Soo had touched her, tingling, aching for another touch. Soo Said nothing but withdrew, slightly, seeming almost reluctant. They gestured over to their sleeping pool, and Nell obliged, hooking her thumbs into her panties and shrugging them off as she went. The liquid felt thick, and oily, around her feet, but a pleasant scent crept up from it, like the last lingering vestiges of a sweet incense. Nell swirled the liquid with her feet, absentmindedly squeezing her breasts, the sensitivity of the skin seemed to have shot off the charts. She heard Soo slip into the liquid behind her, felt their tendrils wrap around her waist, leaving that tingling electric feeling behind. Felt their tendrils wrap around each thigh and quest in towards her sex. Soo was deceptively strong, easing her backwards gently, practically plucking Nell off her feet and settling her into the oily dark liquid. The subtle bowl-shaped curve of the 'bed' was comfortable. "It is fascinating where your species grows this 'hair', Friend Nell." Soo murmured, tendrils wriggling through the trimmed thatch of hair Nell kept between her legs.
Nell could only laugh weakly, body feeling hot, electric, energized, euphoric. "Soo... shut up." she breathed.
A bobbing of Soo's eyes mirrored Nell's dazed mirth. "Certainly. Please let me know when you wish to procede."
Nell's nod was cut short and she gasped as Soo's tendrils slid slickly over her mound, easing her sex apart, opening folds with the gentlest of caresses. She bit her lip when it slipped inside her, curling up against and tickling her oh-so-sensitive spot. Another found its way to her clit, swirling around, teasing the already hardened nub. She felt Soo's thick slime trickle out from between her legs, tingling over her thighs. Tingling inside her, it felt as if each part of her was set alight with sensitivity and pleasure. Nell panted in delight as Soo's tendrils slid all about her nethers, pumping and filling her and withdrawing again, teasing clit and g-spot, lips and folds. And though Nell was brought to quivering heights, back arching, legs squeezing together, and gushing hotly into the oily liquid, it soon felt... lacking. The tendril stuffed inside her not quite enough any more, an emptiness that grew and wouldn't let her be satisfied. It became clear there was one thing on hand that would fill that void inside. "O... oho...kay... Soo. I'm hahh... I'm ready f-for more." Nell gasped out "T-to continue!"
She felt Soo rumble in approval. Soo straightened and Nell was left feeling needy as those tendrils withdrew from her. Despite the shivering orgasm she'd just had she hadn't wanted it to stop. Her pussy and thighs felt warm, almost hot tingling delightfully. Looking down her pussy was engorged well beyond its usually, lips large and puffy, skin reddened and sore. The sight sent another wave of pleasure through her, and she shook with an aftershock of delight. Through half-lidded eyes she watched Soo turn around, lining up the tapered tip of their slug-like lower half. Slowly, it began to push out at her, the smooth skin parting, expelling a thick tube the size of her wrist. Greedily, she grabbed at it, helping Soo stuff it inside her. Stroking it like it was a lover's member as she guided it inside, pulling and grinding against it. As it slid deeper and deeper inside, far deeper than she thought it could go, she moaned out in raw pleasure, one extended primal groan of ecstacy. Nell felt a gentle pressure, deep inside, and the feeling of something opening up inside her.
The first egg throbbed through the appendage and she doubled over, her entire body tensing as a thunderous orgasm crashed through her. She felt hot fluid spurt from between her legs, trickling down her thighs and into the oily liquid below. Another egg followed shortly after, and then another, and another, ramping up speed. Thick slime spurted out from her sex with every egg that was deposited.
That hollowed feeling she had felt subsided, replaced by indescribable ecstacy. Nell squeezed Soo's ovipositor, urging each egg inside, her chest felt hot, prickling and aching, and her chubby belly slowly grew. Every few eggs brought her another, ever greater surge of pleasure, and her legs ached with the intensity. She panted, eyes rolling back in her head as Soo filled her up. She ground her hips into their appendage, eager, no, desperate for each egg, trying to pull it deeper into her pussy. Her belly began to swell with the sheer volume of eggs, as Soo's abdomen slowly deflated. She now looked several months pregnant. Nell squeezed at her breasts in delirious pleasure, finding herself surprised even through the haze as thick cream squirted from her nipple. Each tit had now doubled in size and achingly heavy with milk. Her belly became increasingly more distented, larger than any human pregnancy, swelling with stretch marks, and still the eggs pumped into her one at a time, a steady march, her body rocking with orgasm after orgasm.
Nell's reached up both hands to help with her breasts, starting to hurt even through all the endorphins, through the pleasure. With methodical motions she massaged them, coaxing milk out in long streams, splattering down her huge belly and quivering legs. She was lost to the feeling, mind turned into overcooked pasta by the torrential orgasms.
And then, with one more egg, that left her shuddering and moaning, quivering around Soo's appendage and dripping from mouth, breasts, and pussy, it was over. Soo's ovipositor slowly withdrew from her with a wet, lewd sound. Nell rubbed a hand fondly over her distended, alien-pregnant gut. Then she passed the fuck out.
She awoke in the med bay on their ship. The shuttle having long-since docked. Her belly was still enormous, and twin pumps kept her breasts emptied. She felt a little like a dairy cow. A face loomed over her, "Ah you're awake."
It took a moment for her eyes to focus. It was the chief medical officer. "That was a brave thing you did, looking after your crewmate like that. The captain has approved several weeks of leave for you. We'll be on hand to help you with the uh. Birthing."
Nell, still hazy, still lost in a sea of hormones and eggs. Only smiled and nodded.
