Jessica exhaled slowly, her breasts lowering noticeably before rising again with the thick cock still nestled between them. Up close she saw the creature had long arms with hands bearing six giant, thin fingers each tipped with long and sharp claws. With each breath, her breasts rubbed against the creature and as she listened to the sentry slowly walking back to the source of the noise, she heard something far more terrifying. A low, snake-like hiss emanated from the creature before her and its hands trembled slightly before slowly moving to touch her.
From how high up it was, it could only grasp her shoulders, easily holding them in its grasp as its body began to buck against her. Its motion was sluggish as though it were still wracked with a powerful exhaustion. Jessica watched its cock rise and fall between her soft breasts and for a moment, her mind was consumed by how lewd her dumb idea had become. Precum began to leak from the tip and she couldn't help but think about running her tongue up and down its length as it continued to fuck her. Behind her, the sentry's flashlight circled around a few times before he was satisfied in not finding anything and he began to leave. His steps were agonizingly lackadaisical and Jessica found it harder to control her breathing as the creature began to increase its speed.
Without thinking, she raised her hands and cupped her breasts, her fingers instinctively resting over her stiff nipples as she began to rub and tweak them. As the door finally closed, a soft moan escaped her and her breathing became labored. She watched her breath, visible in the cold room, washed over the cock before her. Something about this; about the absurdity of the situation, about being used by some inhuman beast, turned her on faster than she ever would have thought it would. Her fingers began to play with her nipples faster and faster while her tongue now hung out as she unwittingly moved closer to the twitching thing. She fought the urge to put her mouth on it, to taste the precum now readily pouring from the tip.
"Fuck it..."
The fight was over faster than she wanted to admit and her mouth shot to the tip where her tongue quickly got to work lapping up the fluid. It was less salty than a human's cum and as she made contact, a small burst of cum shot into her mouth. Jessica, relieved of any hesitation, moved her mouth down over its head and relished in the constant stream of rich cum slowly pooling in her mouth. She swallowed only once she couldn't hold anymore, slowly and with her head lifted so she could feel the hot and thick liquid pouring down her throat in a series of controlled movements. She could feel its warmth all the way down to her belly as its heat radiated through her and held off the chill from the cold air. Jessica panted for a moment, a few trails of cum hanging from her lips and shining bright blue in the light beneath her, before she heard the creature let out another slow hiss. Jessica quickly lapped up as much precum as she could before drooling over her breasts and spreading it between them to better accommodate the creature.
Her hands pressed into her huge and malleable breasts to hold them tight around the pulsing cock she know actively pleasured. The creature, still mostly silent and largely unmoving, gripped her shoulders just a tiny bit tighter though she couldn't tell if that was from it waking up or simply enjoying her too much. She moved up and down the length of its shaft while her mouth remained planted over its head as often as she could get it. Jessica couldn't understand why, or at least failed to really consider, that its cum seemed to taste better as she swallowed more. Soon the salty taste was gone and replaced by a tinge of something sweet. She would eagerly wait for it to fill her mouth again before letting half of the searing hot liquid fall to her breasts, now causing steam to form in the air from the difference in heat, before swallowing the other half and relishing in the feeling of it sliding over and in her.
It was sheer debauchery though after her second gulp she could barely think straight. She felt a kind of soothing numbness not unlike a hard buzz just on the cusp of reaching a properly drunken state. She fell slightly lower, nuzzling the slick cock against her cheek as she giggled and smiled like a loon before aimlessly flicking her tongue across the head. She maintained her hold on her breasts but now she slowed down as she the numbness took her faster than she realized though had she known beforehand, there's still a chance she would have swallowed.
Any curiosity as to where she was or what she was sucking off left her. All she wanted to suck on this creature's cock with her plump lips until it erupted in a fountain of sweet and warm cum that she could massage over her breasts. As though it had read her mind it took hold of her head, its gangly fingers easily holding the entirety of her head within its grasp, Jessica relaxed and let it guide its cock down her throat, thankfully slow enough that she could take it with relative ease. Inch by inch until it reached as far back as it possibly could, Jessica remained calm and flicked her tongue underneath the shaft until it pulled her back and pushed back in.
She let go of her breasts to play with her nipples, teasing the stiff nubs intensely. She pulled on them, flicked them back and forth before moving her hands up to coat them in cum before rubbing it over her nipples. It continued to push into her mouth with force yet it never pushed too deep or too hard for her to handle. Her body continued to delve further into drunken pleasure as the precum continued to seep into her belly with each thirsty gulp. Without thinking, she reached down to begin removing her pants, rapidly slipping them and her thong off without any struggle. The cool air met her skin and sent shivers up her spine though something about this only made her want this more.
Her fingers quickly found her soaking wet pussy and began to work her clit before she got tired of her own teasing and began to finger herself. Moans escaped her whenever the creature's cock wasn't far enough in her mouth to choke the lewd sounds. The creature hissed louder this time as it held her head a little tighter, pushing in one last time before releasing its load. Jessica braced herself as she felt its cock pulsing hard.
It erupted as she hoped it would: her mouth exploding in a shower of hot cum that quickly splattered her chest and made loud, satisfying noises as it struck the floor beneath them. She did her best to swallow as much as she could, loving the now addictively sweet flavor and the warmth cascading over her. Gulp upon gulp began to fill her stomach which now felt hot even on her skin. Her mind felt lost as though it simply melted away into a sea of emotions filling her. It let go of her and she fell back from how weak her body felt; her shins down on the floor and her legs spreading. The torrent of cum continued to pour over her, splashing across her belly as she panted and squirmed under the towering creature.
"Ha...haaaaaa."
Jessica could hardly form words in her own mind as she continued to finger herself and lap up whatever cum reached her face. Only when her body was thoroughly covered did it stop and the creature returned to its silent dormancy. She lay there for a while, her body unwilling to move and her mind unwilling to consider that she was still somewhere she wasn't supposed to be. She decided to rest for a moment, enjoying the still hot cum keeping her warm on the cold floor.
