All of the women do.

Johnson's call for volunteers met with an instant chorus from the twin blonde scientists and corporal Inez. Joanna and Kelly joined in the clamour a split second later, realising that not volunteering might arouse suspician. Even Holly, still crawling on her leash managed to yap enthusiastically. Johnson looked the women over and pondered who to pick.

"Sorry girls, but I'll probably need your brains in there." He said to the clearly disappointed twins. "And I still don't trust this exec bitch out of my sight."

Joanna felt apprehensive as the union boss eyed the three Angels. Reaching a decision he pointed out Kelly and Inez.

"You two will do just fine." Johnson smirked. "Get your pretty little asses into them alcoves."

Inez complied immediately with Kelly a couple of heartbeats slower and visibly trembling as she backed into the vacant space. The alcoves were just wide and tall enough to take a human body and each had a pair of hand grips set at head height. A variety of panels could be seen set into the sides of the alcoves, but their purpose was unclear at the moment. When Inez and Kelly were in place and gripping the handholds the rest of the party watched expectantly. For a couple of seconds nothing happened and there was a moment of anticlimax, then panels in each alcove suddenly hissed open making everyone watching jump. Flexible black metallic tentacles snaked out of the panels and wrapped themselves around the wrists and ankles of the two volunteers. Both the women cried out in surprise at the speed and efficiency with which they had been snared. The two Angels tugged at the restraints, but were held tightly in position.

"Settle down girls." Johnson ordered. "We knew this was going to happen. We just don't know why or what happens next."

Joanna fought down the urge to rush to help her two troopers. Naked as she was there was nothing she could have done anyway, but her loathing of Johnson grew even more intense. A second hissing from the alcoves drew her attention as fresh tentacles appeared in both alcoves. These came from panels set in the back walls just below the trapped women's asses. The tentacles slid between the quivering thighs of Inez and Kelly, then reared up and round to point ominously at their unprotected pussies. The tentacle heads were rounded and swayed from side to side as some kind of onboard guidence locked onto the women's vaginas. With amazing speed they shot forward, causing the trapped troopers to let out high pitched squeals of protest as they were penetrated. The blonde scientists stepped forward and examined the impaled pussies and the tentacles closely.

"These readings are pretty strange." One of the beautiful scientists said, scanning Inez's groin with a device from her pocket. "If I interpret it correctly it's an energy exchange of some sort."

"I concur." Her Twin agreed, examining Kelly's tentacle intruder. "They're beginning to vibrate. I believe they are drawing energy from the subjects to power something inside the room. The amount of energy drawn seems to correspond to the sexual excitement of the subject."

"Spendid." Johnson gloated and produced the device that controlled the rings. "In that case I guess I can speed the process up."

Johnson touched the control device and the gasps and moans from the two trapped Angels made it clear that he'd set the rings stimulation on high. Though their wrists and ankles were held tight Inez and Kelly's body's were free to writhe and quiver under the combined **** of the tentacles and the rings. The two women moaned incoherently as sweat drenched their nubile bodies, soon their hips were bucking wildly as they repeatedly orgasmed. This continued for several minutes and Joanna was startled to find that her own hand had unconsciously began to rub at her pussy. Dragging her eyes from her comrades she saw that the others had also been aroused by the sight. Johnson had Holly's head in his grip and was fucking the exec's mouth as he watched the spectacle. The scientists had squatted beside each other and each was frotting her twin's clit as they stared in rapt attention at the Angels.

As suddenly as it had began the process stopped. The tentacles wrapped around the wrists and ankles of Kelly and Inez witdrew back into their panels and the two Angels sprawled to the floor. The two blondes reluctantly disentangled themselves and examined the two slumped troopers.

"They're alive." One reported. "But severely exhausted."

"The technology is similar to your implant." The other added to Johnson. "It draws sexual energy for power, but in this case the energy drain is much higher. They'll probably sleep for a few hours and be ravenously hungry when they awake, but I can't see any long term ill effects."

"Whatever." Johnson shrugged, clearly not overly concerned about the Angels. "The question is can we get inside now?"

As if in answer to the union boss's question lights surrounding the door blinked on and a second later the doors themselves slid back into the walls. A pulsing purple light flooded out from the room behind. Those in the party still standing or in Holly's case kneeling exchanged glances as the doorway and eerie light beckoned.
