"Now we have to do this for the realz," Barbie announced. "Remember, this is a drill." She picked the power drain from the clamp where she'd put it and mounted it back onto the chair.
Jolene, having caught her breath, nodded. Her lower body was still buzzing from the intense procedure she'd just been introduced to. "Okay. Let's do this."
Lola hugged her. "You did great. I'm in awe."
Jolene pressed a big kiss on the woman's lips, enjoying the closeness and buying herself a little more time. After some intense tongue play, they both came up for breath. "Thanks, sweetie."
"That was sweet, but enough of that, or count me in," Barbie said, wrapping her arms around both her excitement engineers. "Now, first check the chair and me. You need to be able to see in an instant if the drain is set up correctly for me. In an emergency, we don't have time to measure things up."
The female power conduit leaned backward and, hovering near the two, spread her legs. Lola let Jolene do the work alone now, as this was her first time.
Jolene estimated the position of the drain compared to the vibration unit, then carefully examined the openings between Barbie's legs.
A female 'power conduit' had a second 'vagina' installed, close to the first, real one. That second vagina absorbed the sexual energy of the conduit. The energy generation was invoked by the vibrational unit and enhanced by the actions of the excitement engineers. Jolene, like all other excitement engineers, had gone through rigorous training to learn every trick in each book about sex known to humanity. An engineer never knew what would get their assigned power conduit excited, and once on active duty, they had to find out as quickly as possible.
The conduit had undergone special modifications to take in and hold as much sexual energy as possible, and the internal wiring would release that into the power drain. Once a power drain had collected enough energy, it 'uploaded' that to the ship's power systems through the drain. The power coming out of the conduit should travel as short a distance as possible, which was why this room was almost next to the reactor.
"Not quite right," Jolene said, reaching out and moving the drain a tiny bit. She'd practiced this a thousand times or more, and her eye for this was almost perfect. Because of that, she'd gotten this assignment.
"Let's see," Barbie said. "Put me on it."
Together with Lola, Jolene moved Barbie over the chair and lowered her onto it. Jolene mentally crossed her fingers.
"Really good," Barbie said, as she was going down. "Almost perfect." She beamed at Jolene. "Best friends, remember? Push me onto it all the way."
That was the next tricky bit. Pushing someone down was one thing, in zero gravity that was something else. Jolene and Lola both held on to the chair with one hand and used the other one to press Barbie in place. The power conduit closed her eyes and gasped.
Jolene theoretically knew what was going on inside Barbie. The drain would connect to her second vagina and, through that, to her energy. She checked the left and right sides of Barbie's head, just below the ear. After a few moments, two LEDs below her ear, under the skin, lit up white. "Perfect connection."
"You're really good." Barbie reached out and slipped a finger between Jolene's pussy lips. She did the same for Lola. "You two make a good team. Now work me up. Let's see how far up the scale we can get."
Jolene shuddered. "You'll have to stop doing that to me or I will be worked up more than you."
"And your point?" Barbie wiggled her finger a bit more. "Tell me you don't want this."
Jolene grabbed the woman's hand and thrust her hips against the finger. She closed her eyes and let the orgasm take over. Her entire body shook as the waves hit. She'd just gotten over the massive jolts from the vibrational unit, and now Barbie was pushing her into this. She knew this was on purpose and also so she had to recover quickly. It wouldn't be often (she hoped) but the life of the entire crew could depend on this.
"Okay. Lesson for today. When we're in a real emergency and I start playing with you, you'll have to stop me and play with me. That's what our job is here." Barbie slowly licked her finger, savoring Jolene's juices. "I'm glad this wasn't an emergency. You taste good." She held up a finger for Lola, so she could sample some as well. As if the second excitement engineer hadn't tasted Jolene yet.
