Riker tried to take you with him on away missions as often as possible, convinced he could look out for you best this way.
The away mission to Epsilon Indi IV was routine on paper: survey a pre-warp civilization's ruins for potential archaeological data, beam down with a security detail, and avoid contaminating the site. But with the Enterprise orbiting above, the hum of the transporter always carried that edge of uncertainty.
You materialized on the dusty plain, tricorder in hand, the alien sun beating down on your red command tunic. Commander Riker stood beside you, phaser holstered but ready, his broad frame a reassuring presence amid the crumbling stone structures that whispered of a long-lost culture.
"Be careful, no unnecessary risks", Riker gave orders to the away team, his voice carrying over the comms with that natural authority. He glanced your way, blue eyes scanning for threats before settling on you.
"You good, kid? First time on a site like this, stick close."
'Kid' landed like a spark, casual from him, meant to steady you as the junior officer. But it ignited something deep, a flush of heat low in your belly that you had to shove down hard. Shame prickled your skin; churning in your belly. This was just a mission, just his manner of speaking, him trying to look out for you.
You nodded sharply, focusing on the tricorder's readings: there were faint energy signatures in the soil, while Riker's hand brushes your shoulder in a quick, protective squeeze, oblivious what his choice of words did to you.
"I've got your back."
As the team fanned out, he positioned himself between you and the denser ruins, deflecting a loose rockfall with a swift arm when the ground shifts.
"Easy there, kid, watch your step."
Again, that word, paired with his vigilant gaze, made your pulse stutter, a rush of blood making you twitching traitorously against the confines of your uniform. You bit the inside of your cheek, ashamed of the arousal coiling tight, imagining his voice in darker contexts.
By the time the transporter chief recalled you, data secured, no incidents, your face burned under the pretense of the planet's heat.
Back aboard the Enterprise, the corridors felt too bright, too exposed. You headed to your quarters first, stripping off the dusty uniform and stepping into a sonic shower to scrub away the mission's grit.
As you got rid off the sandy dust of the windy surface, you tried to scrub away the echoes of Riker's protectiveness as well. The way kid rolled off his tongue like endearment, like a promise. It stirred a need you've burried, burried deep for years now. One that feels oh so wrong to voice.
Later, off-duty, you found yourself at his door, heart hammering as it slides open. Riker looked relaxed in civilian slacks and a soft shirt, a glass of synthehol in hand.
"Hey. Debrief's informal tonight. Come in."
With a soft smile he gestured to the couch, but you hover, words sticking. He noticed immediately, setting the glass down.
"Everything alright? You seemed off after the beam-up."
You sank onto the edge of the cushion, trying to put as much distance between the two of you without offending him, yet managing your guilt and stared at your hands.
"The mission... you called me- called me something. Called me kid. It- it did something to me. Made me feel... safe, but also...", heat flooded your cheeks. "Aroused. I'm ashamed of it. But I... I want you to call me that during... us. Doing stuff. 'Kid' or 'son.' Like, in bed. If that's weird, forget I even asked, it's gross and I'm making it weird-"
He moved to sit beside you, close but not crowding, his hand warm on your knee.
"Hey. Hey, none of that. It's not weird. It just means you trust me a lot. I like looking out for you, calling you kid on the mission just felt natural. And in our dynamic? Hell yes, I'm on board."
His smile bloomed, eyes lighting with that gentle authority you crave, the kind that's just for you, none of his other personnel.
"We'll make it ours. But only what feels right, tell me if it's too much."
Relief washed over you, mingled with anticipation.
He pulled you into a slow kiss, thumb stroking your jaw.
"Will you do this for me, kid? Let me take care of you tonight?"
"Yes", you whispered, the word unlocking everything.
He lead you to the bedroom, the soft glow of starlight filtering through the viewport, a reminder of the vast galaxy outside, while the Enterprise's warp core thrummed faintly below decks.
Riker undressed you methodically, tunic first, then pants, his fingers lingering on your skin. Naked now, your body exposed, cock already half-hard from his proximity and the anticipation of what he might do tonight.
He circled you, appreciating. "Look at you, pup, so eager and ready for me. Good boy."
The praise sank in like velvet, easing any lingering doubt.
"Sit on the bed", he instructed gently, voice low. "Everything fine so far?"
You nodded, and he smiled.
"Touch yourself for me, kid. But follow my lead, start slow. Wrap your hand around that sweet cock of yours. Grip it firm at the base, then slide up, thumb over the tip. Feel the ridge? Circle it, light pressure. Feels great, doesn't it?"
His words guided you, sensations blooming. The warmth of your palm, the sensitive skin pulling taut as you stroke, sparks shooting up your spine. You watched him watch you, his own arousal evident in the bulge of his pants. So far he was paying no mind to himself yet, just enjoying watching you slowly get lost in pleasure, staying fully clothed.
"Good, just like that. Now squeeze a little harder on the upstroke, twist at the top. Imagine my mouth there, sucking you deep."
Your breath hitched, hand moving faster, but he shook his head.
"Slower, pup. Edge it, stop when you're close, then start again. Dip your fingers lower, trace your entrance. Wet yet? Push one in, curl it forward. Feel that spot? Rub it steady. Nice and slow."
Slick heat coated your finger as you obeyed, the dual touch making your thighs tremble, ass clenching with need. The shame from earlier evaporated slowly under his gaze, replaced by pure want.
He unzips his slacks then; thick, veined cock springing free. Without any sign of rush he took himself in hand and started slowly stroking himself. His eyes still glued to your body.
"You're doing so well for me, son. Can you be a good pup for me? I bet you can, just for me. Add another finger, stretch that hole open."
The stretch burned sweetly, walls yielding as you pump, cock throbbing untouched now.
"Faster on your fingers, but keep it light on your sweet little cock, flick the tip with your thumb. Build it, kid. Don't come yet."
Waves of pleasure crested, your body arching, moans echoing softly in the cabin. Riker kneeled before you, hands on your thighs, almost reverently stroking them.
"Stop now. Hands off."
You whined, but obey, your body humming.
He leaned in, licking a stripe up your dick, then sucked it into his mouth, tongue swirling. Sensations exploded, wet heat enveloping, suction pulling at the nerves. His fingers replaced yours, two plunging deep into your entrance, scissoring.
"Taste so good, pup. Relax for me. You're doing so well. Everything okay?"
You nodded frantically, and he adds a third, the fullness pressing against your insides, grazing your sweet spot with each thrust. He pulled back, standing to guide you onto all fours on the bed.
'I'm gonna mark you as mine. Claim you, it's a promise I'll always watch out for you. Will you take it for me?" Lube slicked his cock, and he pressed the tip to your entrance, not ass, but the front hole, stretching you wide. The initial breach stings, walls parting around his girth, but he goes slow, inch by inch, giving you time to adjust, as if it's your first time.
"Breathe, son. Feel me filling you? So tight, so perfect."
Once seated, he rocks gently, hand coming around to stroke your cock in time.
Pleasure coiled tight, the slide of him against your depths sending jolts through you. But he stilled, cock buried deep.
"Hold still, I'm gonna piss inside you now. Claim you fully."
Warmth flooded you, his piss mixing with your slick, the pressure building oddly erotic, a full, possessive heat that makes you gasp. It seeped out around him as he starts thrusting again, the wet sounds obscene, making you whine.
"Good boy, taking my piss like that. Feels good, doesn't it?" He withdrew carefully, the liquid trickling down your thighs, and pulled you up.
"We're taking this to the holodeck, pup. I wanna show you off."
The program activated: a dimly lit Ten Forward recreation, holographic crew mingling, jazz floating from the band.
You're in a simple loincloth, collar around your neck. Riker's doing.
"Walk among them, kid. Let them see."
Heart pounding, you wove through the crowd, fabric slightly tenting over your cock, the exposure electric. Whispers from holograms heightened it, making you feel raw and vulnerable. Riker catched up to you, hand soft on the small of your back, his voice low in your ear.
"Piss for me now, son. Right here, in front of them. Will you do this for me? Mark the floor as mine."
Shame twists with thrill; you hesitated, but his hand on your back steadies.
"You can, pup. I'm proud already."
Bladder full from earlier tension, you let go, a hot stream arcing onto the deck plating, splashing warm against your feet.
The holograms glanced, murmuring, and Riker praised lavishly, "That's my boy. So brave, so obedient. Look how they watch you. So handsome, letting go just for me. All of them jealous, not having a son that trusts so unconditionally."
Arousal surged, your cock dripping pre-cum.
He bent you over a table then, shoving the soft loincloth aside and entered your ass this time, lube easing the way, the ring of muscle yielding to his thickness. The burn faded to fullness, each thrust grazing deep.
"Fuck, kid, taking me so well in front of everyone. They can't keep to themselves, you're too pretty like this." His hand wrapped around your throat lightly, choking just enough to heighten the rush, oxygen dipping as pleasure spikes. Holographic eyes on you amplified every sensation: the slap of skin, the stretch, the exposure, Riker's soft grunts.
"Come for me, kid, let them see. You earned it."
You did, shattering with a whine, walls pulsing around him, release spilling onto the table. He followed, groaning, filling your ass with hot seed.
He scooped you off the table, pressing your back against his still clothed chest.
"Perfect, pup. So proud."
"Computer, end program." The bar fades to grid lines, safety reaffirmed.
Back in quarters, Riker draws a bath in the tub, warm water cascading from hidden emitters. He washes you tenderly, fingers massaging soap into your skin, kissing the marks on your neck.
"You were incredible, kid. Everything feel good?"
"Yes", you murmured, leaning into him, the galaxy's stars still wheeling outside. In his arms, shame was a distant memory, replaced by deep, blooming trust.
