Based on the Star Trek: Theurgy 'canon' that Andorian Shens have, well, phalluses.
The Taste of Blue
It wasn't every day that a Starfleet officer was brought to his knees before the pulsating, twitching, slick mightiness of a near neon-blueberry-hued lady-penis.
But good officers adapted.
That was Ensign Bradward Boimler's opinion, and key to success alongside over-preparation, at least.
From her position next to the couch set against the far wall of their temporary quarters, which, apparently, Mariner arranged for them to use by calling in a favour from Commander Ransom – something about not narcing on him for assault with a deadly weapon – Mariner hardly seemed to agree or share Boimler's penchant for implacable calm in the face of blue lady-penis.
"Why are you not freaking out right now?" she asked, balanced on one foot, midway through a struggle with a pant-leg that was clinging on like Boimler to his ex-girlfriend. Which was, needless to say, very clingy. "This is a total let down."
"Thanks," Jen grunted as, on his knees before the edge of the bed, he cradled her thighs, squeezing rhythmically while watching her phallus swell up.
Mariner threw her an apologetic wince. "Well, not that."
"Are you serious? Jennifer Sh'Reyan. It's in the name. Andorian are Quadrigender," Boimler noted in what he thought was a measured and sagacious tone befitting a future captain, all while stroking his girlfriend's dick, pumping the sticky shaft while she humped into his hand. Captains could do that too. Right? "Shens have ovipositors."
"Yeah, I know that. I mean, I didn't until '77 when I had that five-some with an Andorian quartet – and, oh, fyi, Chans make the best sissies I've ever seen-"
"Oh, yeah," Jen interjected, her hand to the back of his head to guide him in towards the open tip of her ovipositor, at which point he just shurgged and leaned in to lick up a dribble of vibrant blue slick. Mm. Tasted like... blue. And blue, apparently, tasted fruity. "The ovipositor isn't just for impregnation, you know?"
"-but how do you know that?"
"Tellarites, Humans, Vulcans, Andorians," Boimler mumbled in a mostly comprehensible fashion while trying to still attend to the needs of their girlfriend's lady-dick. He'd give himself a grade of 80%. Not great. Unacceptable. "'ey're uh 'ounding 'embers. 'Asic ana'nomy."
"You're a helmsman, not a doctor." She shook her head, possibly at herself. "Also, don't talk with your mouth full. It's bad manners. Food or cock."
"Well excuse me, miss manners and protocol." Boimler's free hand – the one not stroking the base of a blue ovipositor – waggled as he pulled back to give the now-naked human woman a half glare, which was kind of hard when he was really hard and she was currently fingering herself. A future starfleet captain did not permit himself to become distracted, though. Did Picard get distracted when... Boimler was too distracted by Jen smacking his cheek with her ovipositor in a clear request for more suckage-of-the-fun-variety to think up a suitable stardate reference and episode ... of Picard's life. "For your information, I got 100% in The Anatomy of Founding Federation Species at the academy."
"Ugh." Mariner blew a raspberry and sulked. "It was totally going to be a huge thing, like, you screaming and running out of the room, streaking the whole ship." With a skittering motion of her hands, she mimed the flight of a little Boimler – speaking of whom, little Boimler was getting a wee bit impatient and drippy – down a hallway and then flailed her arms about as if she was being dissolved by a Horta. " I had everything planned out, even hacked inspection schedules to make sure my mom was going to be touring deck two section seven right now so you'd be sure to run by her."
"Okay, it was not going to be a thing," Boimler insisted, fighting back against Jen's whine and a few questioning tugs to his neck and shoulder given that this was more important than glistening blue ovipositor lady-penis, "because (a) while I like women, dicks are fine - it's the 2380s, Mariner; stop living in the 2360s – (b) I do my research, so of course I knew that she had an ovipositor, even if I hadn't learnt it in class, and (c) I never freak out-"
"You freaked out and had a panic attack when the warp core was three milicochrane out of alignment." A flurry of blinks culminated in a scoff while Mariner resumed playing with herself. "Heh, cochranes."
"It was making that little pinging noise!" Boimler most assuredly did not whine in his warp-core simping voice. "It was so ... pingy."
"It-
"Guys, less flirting, more fucking, please!" Jen groused with her hands curling into Boimler's hair. His throat wasn't exactly suitable for egg-laying (he'd dodged that bullet once and learnt his lesson) so he angled his mouth lower to press his nose into the slit of her womanhood.
It was at that juncture, occupied in his efforts to get 100% on this new exploratory test or, at least, to practice so that he could one day do so by exploring the myriad complexities of a clitless pussy and ball-less cock, that he felt a presence looming over him. On turning from his task, fingers replacing his tongue, he found that Mariner had taken up a position behind him.
The complex series of straps that hung low on her hips and locked into place around a thin, twisting purple dildo that was vaguely reminiscent of a complex organic work of art or the genitals of Species 8472's fifth sex, was not an encouraging sight as Mariner tightened herself up and double checked the settings of the vibrating second dildo that had slipped into her pussy.
"Uh." Boimler licked his still blue-and-fruity-tasting lips, clinging a little bit more desperately to Jen's thigh. "You're going to use that on Jen, right?"
Mariner just cocked a brow while Jen cocked her cock... which was a weird gesture probably accomplished due to the additional muscle groupings around the Andorian Shen's pelvis that were used to force eggs down the ovipositor's shaft and into a, well, he hoped not a throat.
100% in The Anatomy of Founding Federation Species for the win.
"Oh, so... I get to go next, r-" Boimler asked, though it was, again, muffled and then cut off entirely by Jen shoving her ovipositor into his mouth, the taste of blue and now something slightly acidic bursting in his mouth as her phallus swelled, the tip opening up to allow his tongue to swirl inside of it in a little teasing gesture that made him wonder why more guys hadn't tried this when she bucked and writhing.
Oral was kind of fun.
"Thank you." Slick finger probing at his rear, circling his hole in a slow tease, Mariner gave her strap on one last review. "I thought he'd never shut up."
At least, Boimler decided as he was sucking away rather happily because ovipositors kind of tasted like candy, they used copious amounts of lube.
And Jen hadn't been inseminated by both a Chan and a Thann, so no eggs laid in his throat was a plus.
A future captain took his victories where he could find them.
