Chapter Text
‘Oh... oh, Commander!’ you moaned, tightening your grip on your commanding officer’s hair as he pounded into you, his breath coming out in sharp pants hot against your shoulder. William Riker was easy to be intimate with. You had an agreement. Work colleagues on shift, then hot and heavy sex when your time off lined up.
‘You like that, huh? Like how my cock stretches you out?’ He growled, digging his nails into the flesh of your ass. He thrust deeply into your pussy, holding you close against him as you struggled to catch your breath. ‘Tell me how it feels.’ he ordered.
‘Uhh...’ your brain struggled to piece together a coherent thought. He gave you a light spank and bit your earlobe.
‘Tell me, Lieutenant.’ He said sternly, teaching down to rub your clit.
The damn door to his quarters chimed.
‘You’re uh... you feel...’ you glanced at the door, still lost for words.
‘Eyes on me.’ He rubbed gentle circles over your clit.
‘Commander, you fill me up so nicely, makes me—‘
The door chimed again. You sighed. ‘Do you need to get that?’
Riker rolled his eyes. ‘Computer?’ He muttered. ‘Who’s at the door?’
‘Lieutenant Commander Data.’ The computer supplied, coolly. Riker let his head drop to your shoulder again, allowing a frustrated whine to escape his lips.
‘I’ll hide in the bathroom.’ You already knew the drill. If you were lucky, you’d get to come... again... when he came back. When he felt guilty he’d do anything to get you off.
‘Just a minute while I see what he wants.’ Riker gently pulled away from you and reached down blindly for his hastily discarded uniform trousers. ‘I swear, if it’s about early 22nd century shitposts again...’
You grabbed a soft blanket from the back of the couch where you had been precariously balanced and draped it over your sweaty body, giggling as you retreated to the bathroom. Riker brushed some carpet fuzz from his trousers and took a deep breath.
‘Come in.’ He spat, perhaps with more venom than was necessary. It wasn’t Data’s fault—the android’s circuits had not been blessed with tact. The doors slid open to reveal Data, standing patiently.
‘Commander Riker.’ He greeted, with a slight cock of his head. ‘I do not wish to intrude.’
‘What’s up, Data?’ Riker asked, offering a tired smile. Data looked toward the ceiling a moment before continuing.
‘Ah. I had a number of questions about a... rather sensitive topic— Commander? Are you all right?’
‘Huh?’ Riker asked, wiping sweat from his brow. ‘Oh. I’m fine.’
‘Are you certain? You are diaphoretic, your body temperature is slightly elevated, and your heart rate has exceeded your normal resting—‘ Data stepped forward as Riker waved his hand dismissively.
‘Yeah, Data, I was just—I was working out. What sensitive topic? Does the Captain need something?’
‘No, Commander. The topic for which I seek information is of a more personal nature. Geordi told me you were a resident expert on what he calls, colloquially, the birds and the bees.’
Riker stared back at the android’s nearly-eager yellow eyes before bursting into laughter. Data’s eyebrows moved together, his brow furrowing.
‘You interrupted—you came to ask about sex?’ Riker asked. ‘And I’m the resident expert? Remind me to have a chat with Geordi some time.’
‘At what time would you like to be reminded?’ Data asked.
‘No, Data, don’t worry about that.’ Riker glanced toward the bathroom door expectantly. ‘I know you probably have a lot of questions—‘
‘I have seventeen questions, the answers to which I could not find to a sufficient degree in the computer banks.’ Data offered.
‘Right. Do you have to know now?’ Riker scratched the back of his neck absent-mindedly.
‘No, Commander. Although I am experiencing a great degree of curiosity, I can wait until you have completed your workout.’
‘Thank you, Data.’ Riker breathed a sigh of relief.
‘Commander?’ Data asked, his eyes flicking toward the couch. ‘I was not aware of your transfer to another role. Your service record does not list scientific qualifications.’
Riker followed the android’s gaze to your crumpled blue uniform top and swallowed thickly. ‘That’s, uhh... that’s not mine.’ He answered.
‘Would you like me to return it to its owner?’ Data offered.
‘That won’t be necessary, she’s—she’s—‘ Riker faltered as he tried to explain the presence of the unexpected object without outright lying to Data, which felt rather inexplicably mean.
‘May I posit a hypothesis?’ Data asked.
‘Sure.’
‘I think that I may have interrupted you engaging in the very birds and bees I came to ask you about. Is that correct?’
‘Something like that, Data.’ Riker felt a flush creeping up his neck.
‘Fascinating. Would I be able to observe the continuation of this activity?’ Data asked innocently, his eyebrows raising as he regarded Riker with an approximation of an expectant look.
‘Data! That’s not really—sex is a private activity, just between two people—‘
‘I have read that many species, such as the Skrreea, may take many—‘
Riker shot Data a withering look even an Android could understand, then carefully proceeded. ‘Listen. I’m sure if you’ve been researching sex, you’re familiar with consent.’
Data nodded.
‘If you were to... observe a sexual act between two—or more—individuals, you would need consent from all parties.’
‘Of course. You would like me to ask the Lieutenant whether she would be comfortable with my presence while you continued?’
‘No!’ Riker exclaimed. ‘I’ll talk to her. You... wait here.’ Riker carefully made his way to the bathroom, shooting a wary glance at Data on his way. He found you leaning against the sink, arms crossed.
‘What does he want?’ You asked.
‘Well, he...’ Riker trailed off, raking his fingertips through his beard. ‘How much did you hear?’
‘Something about consent? You didn’t sound too happy out there.’ You frowned, teaching up to gently rub Riker’s shoulders.
‘So you know that fantasy we talked about? Putting on a show while someone watched?’ He asked.
‘Yeah... why? Does Data want to watch us?’ Your hands stilled as you considered the possibility. Data was interesting—handsome in the clean, deliberate way that statues are often handsome, and desperately curious. But when you had pictured yourself and Riker dabbling in exhibitionism, you had someone a little... less like a colleague in mind.
‘He wants to learn about sex.’ Riker rolled his eyes, the blue irises flashing in the light. ‘Geordi told him I was an expert.’
‘And as with warp engines, he is rarely wrong.’ You smirked. The corner of Riker’s mouth quirked downward.
‘I’m being serious. What do you think?’ Riker asked, placing his warm hands firmly on your hips.
‘I’m... kinda into it.’ You shrugged. ‘We have been talking about getting a little kinkier. If it also happens to be educational, and you make me come a couple more times, I don’t really see any downsides.’
‘Other than the fact that Data and I both serve on the bridge and he’ll have seen my junk.’
You giggled at Riker’s serious expression. ‘He’s an android, Will. He’s awkward, but not exactly predisposed to making things awkward on purpose.’
‘You have a point.’ Riker took in a slow, deep breath, chewing the inside of his cheek before meeting your eye again. ‘So. We doing this?’
‘I’m game if you are.’ Your pussy clenched a bit at the thought of finally trying something you’d fantasised about for years.
Riker gave a short nod and left the bathroom. Data was standing in the same spot, still gazing expectantly toward the bathroom door. Riker stood in front of you protectively.
‘She’s okay with it, so I’m okay with it. You can observe.’
‘Thank you for the opportunity.’ Data chirped. ‘May I ask questions throughout the act or should I refrain until after you have reached a conclusion?’
‘Uh... how about you wait until after.’ Riker furrowed his brow as he took your hand. ‘This is Y/N.’
‘Lieutenant Y/L/N. You are in the xenoepidemiology residency, are you not?’
‘Yeah. We worked on that funky virus a while back.’ You smiled sheepishly, tightening the blanket around you, suddenly very conscious of your nakedness.
‘Okay, enough of that.’ Riker shut down the introductions. ‘Data, for you, this is like watching an experiment. For us, it’s very intimate, and neither of us have had an... audience before.’ He began pulling at his uniform zipper.
‘I understand. I am aware of a sort of observer effect—‘ Data’s mouth snapped shut as Riker waved his hand dismissively.
‘Yeah. Anyway. We’re going to take this to the bed. You can sit on that chair in the corner.’
Data smoothly lowered himself into the plush chair in the corner of Riker’s bedroom and folded his hands in his lap. Riker looked over at you and nodded, signalling that now was as good a time as any to get back into it. You dropped the blanket, face turning red as a strange feeling of shame washed over you. It felt taboo, yet Data wasn’t really a person, was he?
These racing thoughts quieted as Riker shrugged off his uniform top and folded you in his strong arms, pressing his soft lips to yours as he pulled you close. You soon forgot about your observer as Riker’s fingers toyed with the short hairs at the back of your neck, his nails lightly scraping the sensitive skin.
You let out a quiet, appreciative moan as Riker’s tongue slid into your mouth, caressing your own as his hand travelled down the length of your spine to settle on your ass, kneading the pliant muscle there. You pushed your breasts against his chest and worked at the zipper on his trousers. He had neglected his briefs when he had quickly made himself decent for his unexpected visitor earlier, and his thick cock was beginning to stir at your closeness.
Breaking away from your kiss, Riker kicked off his trousers and sat on the edge of the bed, patting the top of his thigh to indicate where you should sit. Bracing yourself against his shoulders, you straddled him, settling into his lap. His hands found your breasts and he pushed them together, peppering kisses over them while his thumbs lazily strokes your nipples. You scratched his scalp just how he liked it, trying to forget the silent android behind you.
‘God, they’re perfect.’ Riker mused quietly, weighing each breast in his hand and smiling up at you. ‘Look how they fit in my palms.’
You leaned down for another kiss, conscious of your pussy resting against Riker’s now half-hard dick. You left a trail of kisses from his lips to his neck, gently running your nails through his chest hair.
‘Please, Commander. May I suck your cock?’ You whispered, rolling your hips in his lap. Leaning back, you bit your lip as you watched him glance toward Data. Riker smirked at you.
‘Permission granted.’
You gingerly got up from his lap, falling to your knees between his spread thighs. Riker’s hands were already gathering your hair into a ponytail, which he wrapped around his fist. You gently kissed his stomach, then left gentle nips and kisses up his thighs as your fingers began teasing his balls. You knew it was time to taste him when he tightened his grip on your hair and made an almost imperceptible desperate noise.
Laying the weight of his cock on your tongue, you began sucking slowly, jaw wide to accommodate his girth. He was like no one you’d had before—not too long, sure, but substantial, and his technique made up for anything he lacked in length. Soon you felt him at the back of your throat, and you swirled your tongue beneath him as he gently pulled your head back. He would set the pace now he knew you were comfortable.
‘Touch yourself.’ He rasped. You glanced up to meet his eyes and saw his jaw slack, a look of complete surrender across his face. Your hand settled on your pussy, gathering substantial wetness before beginning slow circles around your clit. Almost painfully aware of Data behind you, you angled your hips downward so the android might make out what you were doing.
‘Good girl. Taking the whole thing for me.’ Riker began thrusting up into your mouth at a quicker pace, completely hard now. ‘Fuck I love that little mouth.’ You moved your hand from your pussy up to his balls, stroking gently over the wrinkled skin. Riker pulled you off of him and you caught your breath.
‘Yes, Commander?’ You gasped.
‘Did I tell you you could stop touching yourself?’ He growled, leaning down toward you.
‘No, sir.’
‘No, sir is right.’ He released your hair and motioned for you to stand, glancing again toward Data. ‘Get in position. This warrants disciplinary action, Lieutenant.’
This time, you looked toward Data as you settled onto all fours on the bed. His yellow eyes flicked over your form, and it looked like he had a question—as though he were filing it away for later. Riker stood and moved behind you, stroking your ass.
‘I think five will do.’ He decided, then lay the first sharp spank down on your left cheek. You yelped in surprise and arched your back. He counted quietly as he spanked you four more times, each harder than the last. When he was done, he bent down to kiss the back of your neck, whispering a gentle ‘good girl’ before kneeling on the floor behind you. He pulled at your thighs and you scooted backward, laying your head down on your arms and grinning as you anticipated what he’d do next.
Riker ran his tongue over the flesh he had just stung, leaving wet kisses to cool your skin. Nudging your thighs wider apart, his tongue met your pussy and you whined a drawn-out ‘yes’ as he began to return the pleasure you’d given with your mouth. His eyes fluttered closed at your taste, and he hummed in pleasure, giving his cock a gentle tug before bringing his hands back to your ass. He gently spread your cheeks apart and moved up to your asshole, tracing the puckered ring of muscle with his tongue.
‘YES, Commander.’ You choked out, arching back further to improve his access. As he lovingly tended to your rear entrance, his thumb found your clit and rubbed insistently. He wanted to make you come once—maybe twice—before entering you again. The high-pitched cries that left your mouth as you revelled in pleasure egged him on, dipping his tongue into you. Soon enough, you shuddered as an orgasm ripped through you, his mouth not letting up until you reached back and tapped at the side of his head. Riker pulled away with a gentle kiss, standing up to run his hands along your back.
‘You’re ready already?’ He asked, and you nodded, panting against the blankets. Riker pressed his cock against your pussy. ‘Words, Lieutenant.’ He ordered.
‘Huh... ‘m ready, Commander. Want your cock. Need you in me, please, sir.’ The words fell out of you as you ground against him, craving the feeling of him filling you up again. He obliged, slowly entering you until his pubic bone was pressed against your coccyx, his hands firm on your hips. A long, low moan left each of you as you adjusted to the feeling.
Riker swatted your ass one more before starting a demanding pace, the drag of his skin against your skin making sparks appear in your mind. Barely comprehensible phrases came out as you quickly lost yourself in the pleasure Riker was so good at giving.
‘Tell me—oh, fuck. Tell me how it feels.’ He demanded, going back to where the two of you left off.
‘So... good... Commander...’ you gasped, and he dragged his left hand up to the back of your neck, pulling you back onto his cock as he thrust in.
‘Take it. Take it. Take my cock, Y/N. Want you to come all over my cock.’ He chanted, his voice low and strained with effort. The walls of your pussy fluttered around him as another orgasm bubbled up inside you. You let out a strangled cry as it washed over you, Riker’s pace only quickening as he sought his own release.
‘Come in me. Want your—oh! Want your cum deep inside me, Commander.’ You encouraged him as you came back to your senses, the wet sound of his cock moving inside you mixing with the regular slaps of his skin against yours to turn you on even more as you realised Data could hear you begging.
‘Fuck, Y/N... gonna... yeah...’ Riker struggled to stay coherent as he came, his seed spilling into you, his cock throbbing as it emptied. He gripped your hips with an almost bruising strength as he held himself inside of you, breathing raggedly. After a moment, he withdrew from you, planting a gentle kiss to the base of your spine before heading to the bathroom to clean up. You collapsed on your side, catching your breath as you waited for Riker to return with a cloth to clean you up.
‘Lieutenant Y/L/N, you should urinate.’ You jumped as Data suddenly spoke.
‘I should—huh?’ You lifted your head to look at him, still sitting politely in the corner with his hands folded in his lap.
‘As a human with a vagina, your urethra is shorter than those in humans with penises. It is recommended that you urinate shortly after intercourse in order to decrease your risk of UTI by seventy—‘ he rambled.
‘Thank you. Thanks, Data.’ You cut him off, suddenly self conscious. The weirdness of what just happened started to sink in. ‘I’ll go in a minute when Wi—Commander Riker is finished.’
‘Inquiry.’ Data said gently.
‘Just one?’ You asked sarcastically. Naturally, this was lost on Data.
‘I have nine more queries in addition to the seventeen I had stored initially. Would you like me to wait until after you have urinated?’ He raised his eyebrows.
‘Uh... no, go ahead.’
