Starship Enterprise, Deep Space.

Captains Log, Stardate 2248.69. Mr. Spock, our first officer, has invited Dr. McCoy and I to witness something he describes as incredibly arousing, yet difficult to understand. With our knowledge of human emotions and biology, he hopes we can help him make sense of it. The direct participants in the event are Lieutenant Uhura, the ship’s communications officer, and Ensign Gaila, our assigned counselor. Both are aware of our observation and fully welcome it.

Gaila’s Orion background allows her to connect well with the crew. She has been quite helpful in maintaining their morale. Uhura’s fluency in nearly every galactic language makes her an excellent asset also. Roommates at Starfleet Academy, they remain very good friends. However, prior to Commander Spock’s invitation, I was unaware of their deeper relationship. Starfleet has sanctioned such relationships since its inception, but they can still be shocking to those not familiar with them. This is the source of Spock’s trouble. I will add a personal note that the relationship does not surprise me in Gaila’s case. From past experience, I know she can be quite insatiable in matters of sex and that it is hard to resist her. As for Uhura, I am learning more about her as time passes. I hope the lessons will soon include her first name.

The two females entered the room and embraced, then directed knowing smiles at the one-way mirror on the far wall. Behind it, Captain James T. Kirk coughed to calm his nerves. He was still unable to believe that he was allowed to witness this. Personal relationships among Starfleet crews were permitted, but usually kept private. He had also thought that the statuesque black woman he was watching, Uhura, was cold towards him and would always remain so. It was an unfortunate effect of his drunken flirting with her at their first meeting. Kirk and Gaila were regularly intimate, but here he was seeing a new side of her too.

Quite a welcome development in both cases, he reflected to himself.

“You should not be so startled,” said the man who sat on his left, Chief Medical Officer Leonard McCoy. “Gaila is an Orion, and their entire species is bisexual. Females are the dominant gender, and as I recall their history they instituted the practice during their first recorded civilization.”

“Interesting, Bones. Can you elaborate?”

“Sorry, Jim, I’m a doctor, not an anthropologist.”

“Oh well. Spock, do you have any comments?”

The Vulcan first officer, who stood at Kirk’s right, held up a hand for silence. “Let us observe them quietly,” he suggested. “We can further discuss this after getting a first impression of it.”

Kirk nodded and turned back to the spectacle behind the glass. Watching was preferable to talking, he mused. Uhura and Gaila were kissing now, and their hands were moving over the bodies beneath each other’s red uniforms. Uhura’s black skin and hair presented an intriguing contrast with Gaila’s green flesh and red curls. Kirk recalled that Gaila’s species had been visiting Earth for millennia, although it was not until the year 2075 that they had revealed themselves. Soon after that, they began interbreeding with humans. Her light complexion and hair, unusual for an Orion, was the result of such genetic mix.

Both females’ bodies were well proportioned. Gaila’s breasts and rump jiggled a bit under Uhura’s fondling, while her own remained firm. The scent of wine and cinnamon flashed across Kirk’s nostrils and he reminded himself that all Orions gave off such flavor when aroused.

“How did Gaila first seduce Uhura?” McCoy asked Spock. “Was it her pheromones?”

All Orions could secrete various chemicals to control the moods of others. This had a profound effect on humans, and thus harshly regulated. Usage of pheromones for unwelcome effect was illegal, punishable by imprisonment and death among both species. McCoy administered vaccines to any Enterprise crewmember who requested them.

“Actually, it was Uhura who initiated things,” Spock replied. “I don’t know the exact details.”

“I was under the impression Orion pheromones could give Earth women migraines.”

“That effect is somewhat diluted in Gaila by her human heritage. Uhura also tells me she finds the headaches a welcome price of their bonding.”

“Interesting,” Kirk remarked.

Uhura and Gaila were more intent on pleasing one another now, the passion evident in their every kiss and caress. Their tongues lashed across one another’s faces, Gaila’s slightly longer and tapered at the tip. Uhura was rough, slapping Gaila’s rear and biting her lip. Then she was tender, slowing down and rubbing the Orion softly through her uniform. Gaila released joyful gurgles during both moods.

Her fingers traveled to Uhura’s blouse and undid the buttons. They also unbound the black woman’s ponytail and straightened her long hair. Uhura returned the attention by pulling down Gaila’s skirt zipper, then fondling the forest green thighs underneath. Their hug grew closer as their clothing became further undone with the close rubbing of one against the other.

Uhura pressed her lips to Gaila’s throat, then stepped back and dropped her blouse and skirt. This revealed her regulation black bra and panties, along with her athletic legs, slim belly, and heaving breasts. Kirk let out a deep breath. It was his first welcome view of the beautiful sight.

Gaila also doffed her uniform, exposing her black underwear, large cleavage, and sea foam hued body. It darkened in color around the erogenous zones and was quite heavy. The latter quality gave Gaila an advantage in the jujitsu she practiced. Here it sparked a lover’s attraction as well. Kirk knew how strong her hips could lock around his waist, how intense her strength could be when one cuddled against it. From the way Uhura was stroking Gaila’s body with eyes and hands, the captain judged that she too was quite familiar.
