Sample Collection

(Author’s Note: Decided to add a small “non-cannon” chapter for a little fun with Tannis)

The lab door hisses shut behind us. Tannis flicks a switch on the wall without looking—smoky-gray shutters slide down over the windows with a soft mechanical whirr, sealing the room in dim, private amber light. The only glow now comes from the holographic displays and the faint violet pulse of her Eridian artifacts.

She turns to me, expression as clinically curious as ever, but there’s a new heat behind those glasses.

“Apologies, Vault Hunter. But Lilith did propose an interesting idea, medically speaking of course. I suspect this will be a far more pleasant extraction than your earlier sample,” she says, voice perfectly level, “I propose an alternative collection method. Oral extraction tends to yield higher concentrations of viable genetic material… and it’s considerably more efficient.”

Before I can respond she’s already moving; gloved hands guiding me back until my hips hit the edge of the padded medical table. She presses gently but firmly; I sit. Her fingers are cool through the latex as they work my belt open, zipper sliding down with deliberate slowness.

My cock springs free; already half-hard from the way she’s looking at me like I’m the most fascinating specimen she’s ever seen. She tilts her head, studying it the same way she’d study an Eridian glyph.

“Fascinating,” she murmurs, almost to herself. “Girth-to-length ratio is statistically improbable. Vascularity exceptional. Pre-ejaculate already present… excellent sample viability.”

She peels off one glove, then the other. Bare fingers wrap around the base, cool skin against heated flesh. She gives a single, experimental stroke; testing weight, texture, response. My hips twitch involuntarily.

“Responsive,” she notes, pleased. “Good.”

Then she leans in.

Her tongue flicks out first; flat and warm, tracing the underside in one long, deliberate lick. She hums against me; low, thoughtful; like she’s cataloging flavor. “Salty. Slightly metallic. Not unpleasant.” Another pass, slower this time, circling the head, collecting the bead of pre-cum on the tip of her tongue. She savors it for a second before swallowing.

“Acceptable pH. Mildly alkaline. Optimal for oral transfer.”

She meets my eyes; clinical, curious, but unmistakably aroused; then takes me into her mouth.

No teasing. No hesitation. She slides down in one smooth motion until her lips meet her fist, throat relaxing to accommodate me. The heat is immediate, wet, perfect. She hollows her cheeks and sucks; firm, rhythmic, tongue pressing flat while her hand twists gently at the base.

The wet sounds fill the lab; slurping, soft gagging when she pushes deeper, the occasional hum of satisfaction vibrating straight through my shaft. Her free hand cups my balls, rolling them with careful pressure, thumb stroking the sensitive skin behind.

She pulls back just enough to speak; lips still brushing the head, breath hot against slick skin.

“Sample volume appears promising,” she says, voice slightly hoarse. “I’ll need to stimulate full release for maximum yield.”

Then she dives back down; faster now, head bobbing with practiced rhythm, throat working me on every downstroke. One hand strokes what her mouth can’t reach; the other massages my balls with increasing insistence.

It builds fast, the sight of her kneeling between my legs, cheeks hollowed, eyes flicking up to meet mine through her glasses while she sucks like it’s a scientific imperative; snaps something.

I thread my fingers through her short hair, hips jerking once, twice.

She doesn’t pull away.

I cum hard, flooding her mouth. She takes it all; throat working visibly, swallowing in steady gulps, lips sealed tight so nothing escapes. One final spurt catches the corner of her mouth as she pulls back slowly, a thick white drop sliding down her chin.

She catches it with the tip of her tongue; thoughtful, almost clinical; then licks her lips clean.

“Delectable,” she says, voice slightly raspy. “Rich protein content. Slightly sweet aftertaste. Excellent sample quality.” She dabs the corner of her mouth with a knuckle, then stands; composed, unruffled, like she just finished taking a routine draw.

“Thank you for your cooperation, Vault Hunter. I’ll process this immediately.”

She turns back to her microscope; already reaching for a fresh slide; as if she didn’t just suck the soul out of me in the middle of her lab.

I’m still catching my breath, cock softening against my thigh, when she glances over her shoulder.

“Feel free to provide additional samples at your convenience. My schedule is… flexible.”

She returns to her work.

I adjust myself, zip up, and head for the door; still half-dazed, tasting her on my lips.

Just another day on Sanctuary.
