Before you could voice an objection Neytiri's hand coiled around you, cradling you in her blue palm as she lifted you up to her beautiful, inhuman face. With her lush green eyes boring into you, you saw the massive finger of the Na'vi's other hand making a beeline towards your shrunken form. You let out a strangled cry as you felt Neytiri's finger press right up against the erection bobbing between your legs, sending a jolt right up your spine. You instinctively tried to push the intruding finger away, but your tiny hands were no match for her.
"Hey, Neytiri! Quit it!" You squawked in protest.
"Can you feel that?" Neytiri questioned, blatantly ignoring your discomfort.
"Yes, as a matter of fact I can! Now please stop!"
"It doesn't feel like a bone..." The giantess continued, her intrigue only increasing as her fingertip gently batted your manhood up and down, making you let out tiny squeaks of pleasure. "It's too...squishy. What is this? Is it an injury?"
"I'll tell you, if you stop!" You bargained, and at last Neytiri relented, pulling her finger away. You took in a shaky breath, bracing for a very uncomfortable conversation. It was time to explain the birds and the bees to a grown alien woman. Boy, this was going to be awkward. Was it too late to go back to playing Na'vi hide-and-seek? Neytiri fixed you with that striking gaze of hers, the desire for information clear in her expression. Yes, yes it was too late.
"Explain." Neytiri said. It wasn't a request.
"This..." You winced, gesturing to your crotch, discomfort written in your every movement. "This is called a penis. It's a sex organ used for reproduction among the human species. All male humans have them. When...when humans encounter something that...that arouses them sexually, something that attracts them, or experiences some form of comfort, their penis becomes stiff and erect, like this. It's called an erection, or a boner. It's-it's not permanent, and wears off pretty quickly. Like I said, there's nothing wrong, it's a pretty normal occurrence." You let out a sigh after your little exposition, glad to have that behind you. You hoped Neytiri would just leave it at that.
But sadly, Neytiri now only seemed more curious.
"So you got an 'erection'..." The towering blue woman rolled the word around on her tongue, as if seeing how it tasted. "...from me crushing you between my feet. Does that mean you were aroused from touching my feet? You are attracted to Na'vi feet? Do all humans derive pleasure from touching someone's feet?"
"N-no!" You shook your head vigorously, not wanting to give Neytiri the wrong impression. You didn't know if the Na'vi had a word for "pervert", but you didn't want Neytiri to think you were one. "Well, I mean, some people-er, some humans are attracted to feet, but not all of them. Not-not to say your feet aren't nice and comfortable! They're actually really soft and smell kinda nice, but-but-but that's not the point! I only got a boner because I was looking at your body!" You froze as you realized that probably sounded worse. Up above you, Neytiri looked less inquisitive and more smug, a knowing smirk appearing on her face. It was fun watching you get so flustered.
"So you are not just attracted to feet, but you are attracted to me too? You find Na'vi women beautiful, arousing? My body gives you a 'boner'?" Neytiri stretched back in her position sitting on the jungle floor, posing like she was on the cover of a magazine. God, this was exactly what you didn't want happening. You were blushing up to your ears now as you desperately tried to salvage this situation. It seemed Neytiri had grasped the human concept of "being a flirt" rather easily.
"W-w-well...yes Neytiri. You are very attractive by human standards. And-and I'm sure by Na'vi standards too! You are tall, athletic, with beautiful hair and gorgeous eyes. A-and other things too... Not to mention, at my size, they're all absolutely massive!" You flashed the Na'vi woman your best attempt at a suave smile, trying to end this awkward question and answer session with a half-hearted joke.
"Very interesting information, (y/n). Thank you for explaining it to me." Neytiri's voice was calm and thankful, but behind her eyes her mind was whirling with ideas. What else could Neytiri do with this "erection" of yours?
