She wriggled in vain against the binding tentacles as the last of her suit evaporated under the alien ooze.  Fully exposed to the humidity of the cave, her body quickly became drenched in sweat at her struggles.   The beast seemed to have an endless supply of appendages, as newer, softer added their presence to the ironlike one holding her arms and legs in place.  These new tentacles worked their way all over her now exposed skin, leaving a trail of slime at their passing.  She grimaced as one began to slide over her nose and force its way into her mouth.   She fought as best she could, keeping her lips and tips pressed tightly together.<br/><br/>She can barely stifle a scream as she feels yet another tentacle pressing against the rim of her anus.   She silently pleads for it not to press any harder against her orifice, but even so it forces its way inside her.  Its rough penetration is very painful to her, as she had never allowed any one to take her ass.  It only becomes worse as she becomes nauseous when she feels the creature release fluids inside her ass, giving her an alien enema.<br/><br/>The horror she is experiencing only grows when the limbs binding her legs pull her apart slight, leaving her sex fully exposed.   Sure enough, she feels a tentacle trace its way across her nether lips, leaving them coated in more of the sticky goo.   She tries hard to press her thighs back together, but it is to no avail...and she is fully at the beast's mercy.  It finally decides to press home its advantage, and the member forces its way between her labia an into her pussy proper.   As if the one wasn't enough, she feels another work its way inside along side the other.  She had never been very promiscuous, so the double penetration was very tight.  One after the other they became to piston into her sex...always one thusting into her as the other withdrew.   It was all she could do to keep from fainting as she was fucked hard than she had ever been in her life.<br/><br/>Finally, it was too much for her and she let out a low moan.   This gave the beast opportunity to add more to her plight, as the tentacle at her lips was able to enter and slide down in her throat.   She gagged against it, but it was of no use.   The creature was now forcing itself upon in all three of her orifices.
