Mumble and stare

The human was now staring at Lashu's four breasts, his mouth still hanging open. The mild pheromones were hitting him. He said in a bit of a daze, "My name is Aaron. You have four tits." That last statement just kind of came out of his mouth. It was what he'd been thinking, and his shocked state didn't let him edit it out.

"What are tits? These?" Lashu said, waving its arms a bit. Lashu's study of English was not that comprehensive since it was based on video and audio transmissions.

Aaron was mesmerized by Lashu's breasts, and his brain was not quite working right with the shock of seeing an obvious alien and the effects of the pheromones. He stepped forward and reached for its mountains. He grasped two, one upper and one lower, and said, "No, these." They were warm to the touch, and the light covering of fur was very soft and smooth.

"Yes, Aaron, I have four tits," it said, using its new word. Lashu liked learning new languages. They each had interesting little tidbits to make them fun to learn. Perhaps it could use the language to help spread peace on this planet. "We call them 'kreitos'. Do you have tits?" it said, looking at his body. Lashu didn't think his clothing could hide any, but you never know with alien species. Sometimes, the anatomy is quite different. One race it had met had kreitos on their backs.

"No, I don't have tits, just nipples," he said, raising his shirt up high enough to show his chest. "Only females have breasts or tits." Aaron was fascinated by Lashu's body. When he was a kid, he'd read lots of stories about aliens, and he'd loved the first Star Wars movies with all those strange creatures in the cantina. Seeing one in real life was bizarre, but his brain wasn't saying it was impossible.

"So, you are a male?" Lashu asked, looking closely at the body presented to it. Lashu loved learning alien anatomy firsthand.

"Yes, I'm a male. You're a female, right?" The tits were the giveaway.

"No, I am neither male nor female."

"So, you're neuter?" he said, remembering his high school German.

"No, perhaps I misspoke before. I am neither male nor female. I am both. I can create progeny, as well as fertilize another of my species to create progeny."

"You're a hermaphrodite?" he said with amazement in his voice.

“What is a ‘hermaphrodite’?”

“A person with both male and female sex organs,” he replied.

“Yes, I am a hermaphrodite. Would you like me to show you?”
