They brought Astra back to the cell and for the next several hours she twitched and compulsively rubbed herself.
“They made me cum over and over,” she said, shaking. “They wouldn’t stop. I begged them. I didn’t want to but I couldn’t help it. That… thing, that machine, it was relentless! It fucked me everywhere!”
The other girls took turns holding her until she finally fell into a fitful sleep.
An indeterminant time later, the girls had already lost track of how long they had been captives, the Others didn’t keep a day-night cycle, the four creatures appeared at the cell door.
The “Step back from the door,” warning repeated and they just looked up from the bench.
The door opened and one of the Others pointed at Dee, “We require you.”
“That’s nice,” Dee said, “I require that you go fuck yourselves.”
The one with the device raised it and the three girls immediately fell to the floor writhing. When Dee could think again, she was on some kind of a table, on her knees, ass up in the air. Her arms were out before her and ‘stuck’ to the table like a bug in a glue trap as was the side of her head and upper chest.
“The fuck are you doing to me?” Dee mumbled.
“Ferzerp harvesting experiment seven requires you.” One of the being said. “Experiment six demonstrated that acceptable amounts of Ferzerp could be obtained through mechanically simulated coitus coupled with chemical stimulation to the human female without destruction of the host body. Experiment seven will determine if electromagnetic stimulation directly to the reproductive organs can substitute for chemical stimulus as obtaining the stimulants require destruction of the host body during the harvesting process. This is inefficient.”
“What the fuck…” Dee started to mutter when the Other holding the wand reached forward with it and she tensed, “No! No! Don’t zap me again, I’ll…”
The want hummed but this time instead of causing pain, the creature put it up against her clitoris and, with an almost physical shock, gave the poor girl intense stimulation.
“Shit!!!!!” She screamed as she convulsed.
The dildo prob snaked forward, rubbing against her now very wet sex. It moved upwards to her anus. Dee felt a wet gel ooze out of the tip against her opening.
“The prior subject reacted contrary to expectation when her anal area was stimulated. Additional study of this phenomenon will commence.”
The probe pushed against Dee’s sphincter and, with a burn, penetrated her ass.
“Oh fuck…” Dee sobbed and began to cum.
