The Enterprise was exploring a Class J nebula, and the ship held position right outside its rather beautiful giant swirls of purples and blues. But even with the exciting view, the bridge was pretty quiet while the ship collected data on the makeup of the nebular gas, and the computer reported on any potentially useful components. Class J nebulae were known for containing deuterium. (Their other claim to fame, which the Captain hoped would not be an issue, was their ability to contain a warp core explosion.) So while the nebula was pretty, the computer searched ploddingly for items of interest and the crew sat back and waited. The only action was a busted console; engineering was called and Scotty himself - along with another engineer - came up to work on it.

With a healthy, happy crew and no emergencies underway, Bones was bored stiff, so he was on the bridge, nagging Jim about his diet. He was explaining how he'd programmed the protein resequencers to give the Captain nothing but salad, when an ear-splitting klaxon turned the bridge into controlled chaos.

"Warning. Airborne impurity. Locking down bridge."

Chekov's voice rang out, "Captain, navigation is offline." The bridge crew watched in fascinated horror as the ship drifted into the nebula, the gas surrounding them and filling the viewscreen.

Uhura's melodic voice chimed in, "Intraship communications are offline, too."

Ensign Sherlock, a previously unremarkable science officer, stated the obvious. "Captain, we cannot speak to anyone outside this room, and we can't control the ship...We're entering the nebula."

First things first. Jim asked, "What about the air, can we survive in here?"

Spock was on top of it, of course. "Affirmative. While we cannot surmise the condition of the crew throughout the ship, we on the bridge are safe. When the computer initiated bridge lockdown, it began recycling our air." There was a dramatic pause before the Vulcan summarized. "In essence, we are sealed in."

Jim added a summary of his own. "Great."

He was immensely grateful that Scotty had come in person to fix the broken console. At the time, Jim had wondered about the Chief Engineer reporting for such a dumb repair, but then he noticed the other engineer with him was Gaila, his luscious Orion old flame. Scott was probably chasing her tail and looking for every possible reason to get down on the deck and under something with her. For whatever reason, the Captain was glad he was around. Scotty, Spock and Kirk set to work trying to figure a way out, so they could save the rest of their ship.

Gaila got out from under the console to catch her breath and stretch for a bit. The illumination on the bridge had been reduced to the amber of standby lighting, probably to conserve the backup cells. Still, she noticed that there was sighing and ogling and surreptitious uncomfortable fidgeting going on all over the bridge. You'd think they'd all been given a dose of pheromones, Gaila thought; she could even smell it. Then it hit her.

It's me, she thought. It occurred to her that she had been a bit…cavalier with her meds. And she had been warned about being extra careful now that she was working in a closed environment…and now it was really closed…

She could shut herself in the head, but the damage had been done. With nothing to do but wait out the lockdown, the bridge crew would normally relax into a professional kind of banter while keeping an ear open for further emergency issues. The banter was taking on a suggestive quality which was - actually, kind of fun.

Gaila sidled toward the starboard exit, which unfortunately had been sealed just after Mr. Scott entered the bridge. Maybe I'll just try to lay low and hope we stand down soon, she thought, just before she felt a hand on her arm. She jumped and turned to find her ex-roomie Nyota trying to get her attention.

"Oh, Ny!" Gaila whispered. "I think something's gone wrong with – "

"Tell me later," interrupted Nyota with a conspiratorial grin. "I need your help with something really, really important."

"What?" asked her friend, interested in spite of herself. She was starting to feel – distracted.

"Do you think there's a snowball's chance in hell that Kirk would do both of us at the same time?"

The Orion girl stared at Nyota for a moment, not aghast, but impressed. Who knew such a fantasy lurked in that prim little brain? They both turned, slowly, to consider their victim, who was swinging the command chair a little, chin on his fist, gazing at the viewscreen, lost in some extremely pleasant thought. Gaila could see the bulge in his pants from here.

"Which end do you want?" she asked and Nyota giggled.

"I think it's only fair I get to fuck him," she said. "You've done him already."

"In sooooo many ways," murmured Gaila. "Okay, here's what we'll do…"

Jim Kirk was indeed lost in thought; he was recalling the first time he saw Nyota, in the Shipyard Bar. He'd fantasized so often about how that might have turned out, had he not been so cocky with that oversized cadet.

He had reached the part of his fantasy where he lifted her up onto the bar and went down on her in front of all the customers when he felt hands on both of his arms. He looked up to see the object of his desire, along with the object of his previous desire, Gaila. Whom he had exploited in order to finagle his victory over the Kobayashi Maru.

"Ladies," he said and gulped. The last time he'd seen Gaila she'd offered to demonstrate Orion techniques for rendering a man a eunuch. "What can I do for you?"

"We have a situation, sir," said Nyota quietly. "We need to talk to you, as privately as possible. Can you come over to the forward tactical display?"

"Um, okay…" He figured they couldn't gut him and leave him bleeding on the bridge, not with an emergency lockdown in place. They each took an arm and led him around behind the panel, where, on cue, Nyota sank down on her knees as though in a faint.

Jim knelt down before her, suddenly concerned, and he got a glimpse of a wicked grin before she wrapped her arms around his neck and her tongue around his, pushing him down and lying on top of him, out of sight of the command pit. It didn't even occur to him to protest, verbally or otherwise; he was too busy thanking every god in the pantheon.

He pushed his hands up under her tunic as she ground her hips down on him; his fingers stroked over the satin of her bra, feeling her nipples swelling under the soft fabric. Gripping him with her knees, she broke the kiss long enough to peel her tunic off entirely, treating him for the second time to a view of her creamy brown skin and demure white underwear.

"Come on," he whispered. "Let me see 'em."

He thought he was hallucinating when she put her hands on her hips and another pair of hands appeared, unhooking the bra and slipping it off her arms, dropping it on the floor. Green hands. So that's where Gaila went, he realized, and he felt her slight weight come to rest on his thighs, right behind where Nyota's ass was snuggling against his cock.

Green hands came around Nyota's waist, slid up under her breasts, as Gaila peeked over her friend's shoulder at Jim. "Want these, Jim baby?" she murmured and he watched as, unbelievably, green fingers curved up to cup brown flesh, squeezing gently, brushing long red nails over the nipples so that Nyota tilted her head back and moaned.

He had already forgotten the question. Gaila laughed and Nyota gazed drunkenly at Jim, and he sat up and forward, both girls leaning back, until his mouth could reach Nyota's breasts and shove Gaila's hand aside, to take a hard nipple in his mouth and lick and suck, listening to Nyota groaning and Gaila squealing with glee. Gaila's hands came up to hold his head against Nyota and Jim's arms reached around them both to get a grip on Gaila's behind.

Jim teased Nyota's breasts for as long as he could stand it – not long, really – and then he lay back down and reached for his fly. Nyota got there first and pulled his pants open, lifted herself up a bit so he could push them down; then she settled back on his thighs where Gaila had been and took hold of his cock. His hips jerked up involuntarily at the first touch of her hand.

"Mmmm," she said. "I've been wanting this for a long time. Ever since you grabbed me in the Shipyard Bar."

"Damn," he muttered. "Me too." She was fingering and stroking him slowly as she leaned up again to remove her panties; he was reaching down to guide her onto his erection when his vision was suddenly obscured. Everything went green and he heard Gaila say, "Now, baby."

He had only a moment to register that what was blocking his view was a beautiful wet green vulva, before said greenness descended to engulf his mouth in a hot genital kiss. At the same time he felt a slick, soft grip slide down to encase his shaft. Both girls were riding him in rhythm, Nyota's hands holding Gaila's hips as they both pinned Jim Kirk to the floor of his own bridge.

Jim held onto Gaila's thighs for dear life, gulping air when he could get it, bending his knees to get some leverage to thrust up into Nyota. His orgasm filled Nyota as Gaila's filled his mouth. Nyota was still thrusting toward her own finish when Jim pushed Gaila off his face and slid down and out from under her, taking Nyota with him. Nyota's mouth came down on his; he held the back of her head with one hand as the other pushed down between them, to find her clit, bringing her to climax as his cock still pulsed inside her. He felt her cry out against his mouth and collapse on his heaving chest.
