"Zeph, I've wanted to get my hands on you since approximately five minutes after we met. A little size difference isn't going to scare me off." I lean up to kiss him again, slower this time, deeper. "Besides, I'm curious about something."

"What?"

"Those adaptations you mentioned. What exactly am I working with here?"

Zeph hesitates for a moment, then steps back and finishes removing his pants with movements that are somehow both efficient and incredibly graceful. When he straightens up, completely naked and glowing like a golden god, I have to remind myself to breathe.

"Fuck," I whisper, because there really aren't adequate words for what I'm looking at.

Zeph is... impressive. In every possible way. His cock is proportional to the rest of him, which means it's significantly larger than anything I've encountered before, and it's glowing with the same golden light as the rest of his skin. There are subtle ridges along the shaft that definitely weren't mentioned in any alien anatomy textbook, and as I watch, fascinated, there's a faint sheen appearing along the length, something that looks almost like oil, but cleaner somehow.

"That's..." I start, then stop, trying to find words that aren't just incoherent appreciation.

"Too much?" Zeph asks, and there's genuine worry in his voice.

"Too much? Zeph, that's the most beautiful cock I've ever seen, and also possibly the most intimidating." I reach out to touch him, then pause. "Can I? Or should I like, sign a waiver first?"

He nods, not trusting his voice, and I wrap my hand around him, or try to. My fingers don't quite meet around his girth, which should probably be intimidating but instead just makes me more determined to figure out the logistics.

The moment I touch him, Zeph makes a sound that's somewhere between a moan and a gasp, and the glow under his skin flares so bright I can see it even in the ship's ambient lighting. The slick coating on his cock transfers to my palm, warm and slightly sweet-smelling, with a consistency that's definitely not human.

"What is this?" I ask, stroking him slowly and marveling at how the substance makes my hand glide effortlessly.

"Natural lubrication," Zeph manages to say, his voice strained. "Nereidans produce it when... when we are sufficiently aroused."

"It's sweet," I observe, bringing my hand up to examine the clear, slightly iridescent fluid.

"It is meant to ease... intimate contact," Zeph explains, watching my face carefully for my reaction. "Does it disturb you?"

"Disturb me? Zeph, this is the most considerate anatomy I've ever encountered. It's like you came with your own built-in lube dispenser." I grin at him, continuing my exploration. "I'm starting to think your people have figured out some things humans are still working on."

"In a sense, we are," Zeph admits, the glow flaring brighter at my obvious appreciation. "Nereidans believe that intimate bonding should be... mutually satisfying."

"Well, you're definitely succeeding on that front. Although I have to say, if this is what evolution looks like when you actually try, humans got seriously shortchanged." I run my thumb over the head of his cock, spreading the slick fluid and watching his eyes flutter closed. "This is going to make things much easier, and also probably ruin me for human partners forever."

"You approve?"

"I more than approve. I'm starting to think your people have the right idea about a lot of things."

As I continue touching him, learning the texture of those ridges and the way the natural lubrication responds to his arousal, I notice something else, a faint echo of sensation that's not quite my own. Nothing overwhelming, just a shadow of what he's experiencing that makes the whole encounter more intense.

"Can you feel what I'm feeling?" I ask, fascinated by the way his breath catches when I stroke him just right.

"To some extent, yes," Zeph admits. "Nereidanss are... sensitive to our partner's responses. It helps us learn what brings pleasure."

"That's incredibly hot," I tell him, and mean it. "It means you'll know exactly what I want."

"And it means I will know when you are... when you are ready for more."

I look up at him, this glowing alien who's watching me with an expression of wonder and desire, and realize that we've definitely moved past casual hookup territory. There's something about the way he looks at me, like I'm exactly what he's been searching for without knowing it.

"More," I agree, dropping to my knees in front of him. "Definitely more."

I take a moment to look up at him, this gorgeous, glowing alien whose cock is right at eye level now, impressive and intimidating and absolutely beautiful. The golden light pulses stronger under my gaze, and I can see more of that slick lubrication beading at the tip.

"Jake," Zeph says, his voice rough with want, "you do not have to—"

"I want to," I interrupt, running my hands up his thighs and marveling at the way the golden light follows my touch. "I want to taste you. I want to see if you're as sweet as you smell."
