When Talia and I reappeared at the campsite the next morning, the others were already up and about. Beth spotted me first, wrapping me in her arms. "OK?"
"Definitely."
I kissed her, and she looked curious. "Mm, something sweet."
I grinned. "You'll have to ask Talia about that."
Beth gave me a knowing look. "Oh, I think you can count on it. Want breakfast?"
"Please - and coffee if there's any left."
Talia smiled. "So, I have some other matters to attend to, but perhaps later it would be possible to travel back with you? You already know much of what is important about this planet, and I think the next part of our work can more easily be done on your world."
"Of course," I reassured her. I did a quick calculation in my head. "If you return at nightfall, it'll be evening too at home."
Talia raised her hand in farewell, shimmering and fading. "Till then," her words lingered in the air.
Marie glanced at me. "I'll send a message capsule, let them know to expect us."
She chuckled. "After all, the envoy of an alien race probably ought to have some kind of welcoming committee, no?"
We spent the day gathering as much information from the instruments as we could, then packing them up carefully. Over lunch Beth gently quizzed me about my time with Talia, and I saw her growing look of wonderment as I described our encounter. "I wonder how their other gender's made, then? And whether -" her sensual shiver betrayed that her question was far from purely academic - "they could be with a human girl..."
She grinned. "But regardless of that, I'm sure Talia won't make us wait too long to discover how things work between us, too. That sweetness..."
"Earth calling Beth," I teased, echoing one of her favourite phrases. "Come on, let's finish clearing all this up."
Talia reappeared as promised as the reddish sun was setting, and we made our way back up the hill to where the portal was still shimmering. This time I was first, Beth and Sarah behind me, and I turned on the arrival ramp to see Marie emerging from the portal with Talia.
Marie stepped off the platform, speaking to the technicians, and after a few seconds the surface of the portal collapsed, dispersed.
The Vice-Chancellor had returned to welcome us back, and he looked distinctly overwhelmed by Talia. "Ah, welcome, Madame Ambassador, er..."
She took pity on him. "Thank you. It will be my privilege to serve our peoples in whatever way I can."
Marie came to the rescue. "It's fine, Bertie. We can introduce Talia to the press at the next briefing - in the meantime, she's coming with us, and we'll keep you informed."
Talia looked around curiously as Marie drove us home from the lab. "Much has changed on your world."
I made a mental note to ask her what she already knew of Earth, and after a few more minutes we arrived at the house. "First order of business, hot showers," said Beth determinedly. "Tim, why don't you go with Marie, and Sarah and I will look after Talia in the en suite."
Marie grinned at me. "Well, I do need someone to wash my back."
She and I were the first to return to the kitchen, feeling very much fresher, and after what seemed a long time the girls reappeared with Talia. I blinked, recognising one of Beth's dresses, and a knowing smile from Beth brought up all sorts of questions, none of which were likely to get an immediate answer - had the girls introduced her to their most intimate items of clothing, had they taken the opportunity to become more familiar with her body as they got clean, or afterwards...
