((I'm back.  Here's the next installment))<br/>Lurker had checked the perimeter.  Bearing the DNA of a host of invertebrates, he could sense the vibrations in the floor and knew that they were safe from the spiders, probably until morning.  He retreated to his room.  He could smell the pheromones in the air.  He could read the sex-scents emitted by Ash and Eva like listening to the moaning of a loud porno flick.  He wanted them.  He wanted BOTH of them, SO bad!  But he could control the urges planted by his programming.   The GenGineered drive to impregnate.  He could control it because of Nurse Carol's sacrifice.<br/><br/>Inside his foregut Carol was wiggling, thrashing, straining to move and trying to scream.  She was bound in tentacles, thousands of them, and couldn't move an inch.  One tentacle was forced down her throat, stretching her mouth so wide open it hurt.  It was pumping a thick fluid that tasted like cum DEEP into her stomach, and her stomach hurt from being stuffed so full.  One tentacle was shoved up her ass, stretching it open like a fist, threatening to rip her wide open but pumping more of the fluid into her.  But the tentacle that kept her screaming, SCREAMING so lound you could hear it if all was quiet and your ear was at his mouth, was the tentacle in her womb.  As thick as a new born baby, this tentacle stretched not only her pussy but her womb itself.  It had to.  It was implanting the "spermatheca".<br/><br/>In insects the spermatheca holds a store of sperm in the female so the male can continue to impregnate her with his sperm for many times longer than he lives.  But humans don't lay eggs.  So Lurker was GenGineered to plant an altered spermatheca inside his victims.  It implanted to her womb as if it were a placenta.  But this GenGineered organ allows his mates to lay eggs.  Thousands of them.  It has to stretch her womb and vagina, that normally have 9 months to stretch and grow, wide enough to accept the "spermatheca".  But she wasn't screaming because she was in the incredible agony that could only be described as having a baby shoved back inside you.<br/><br/>She was screaming in orgasm.  The chemicals in the fluid (made to taste like cum by the aliens, who felt the degradation would further lower human morale to resist the invasion) FORCED women to orgasm.  She was thrashing in his stomach, trying to make the tentacles fuck her HARDER!<br/><br/>Thankfully, Lurker had the presence of mind to try and do some good.  The chemicals in that fluid may be addictive, (so she'll crave for him to impregnate her and "feed" it to her for months) and induce ovulation and hyperfertility but he managed to make the alien computer give them curative powers too, on the grounds that he could impregnate more victims if he made them healthier.  So immersion in the fluid not only provided the antidote to the spider venom, but would heal any diseases she'd had and restore her hormone balance to that of a 20 year old.  It's still a high price, even for a youth serum and cure all.<br/><br/>Lurker relaxed and absorbed the sensations from the other tentacles.  Besides the tentacles up her nose feeding her air, and the one in her urethra draining her urine, the rest of the thousand tentacles binding her in place so she can't escape, are tongues.  Yes, thousands of taste buds on every inch of her and every one tells him she's DELICIOUS!  If only he didn't have to impregnate her.  In the meantime he has a few more hours to savor her flavor.  He wraps his arms around her stomach to embrace her and gently rocks her up and down on the tentacle in her cunt.  She sighs and shudders in "pleasure" at the extra sensation.
