The Biology teacher called upon the new student with his hand raised, "Yes?"
Mike lowered his hand, "So... only the females have children here?"
As far as exchange students went, Mike was quite beautiful, what being from a parallel Earth. He was sixteen and quite pale, a little taller than average, physically fit, with dark blue hair and shimmering azure eyes. What stood out the most was his retractable butterfly wings that were a combination of dark blue with black trim. He had been in the school a few days, and had already noticed he was popular with the girls.
But Mike only had eyes for Jillian, the lonely, goth girl who sat in the back.
The teacher squinted slightly, "Uhh... is there another way?"
Mike nodded energetically, "Why yes! You see where I come from, there are far more males then females. So the males have to compete for the female's attention. When she has enough males who have shown off their willingness to mate, she will declare that she is 'in the mood', and the male will begin the ritualistic blood letting."
The room went quiet.
"You have to take turns stabbing one another. The purpose to show how fast you can regenerate from your wounds. But it's not a numbers game, more like... ehhh... Professional Ice skating. It's not enough to just injure one another, but to do it with STYLE." The cheerfulness in Mike's voice was both noticeable and quite disturbing, "If you inflict a grevious wound, yet they don't pass out, that looks very good for them. So it's more popular to stick with a series of short, shallow cuts." He held up a finger, "but remember, you might need to protect the female if she selects for the mating process for producing a FEMALE." Mike shuddered a bit, "A pregnant female will be subject to attacks by other females, so you shouldn't just demonstrate your ability to survive, but to fight as well."
The teacher blinked and looked rather pale, "Really?"
Mike nodded, "Oh yes. There's all sorts of youtube videos about it back home."
The girl sitting next to him asked, "But what if it's to be a male?"
Mike pointed at her, "Good question! That's why we have to demonstrate how well we regenerate! When the final winner is selected, the male gets to go back home with the female, who spends the next few days feeding him, preening him, and getting him in tip-top shape. Then, when she's ready..." He paused for effect, before speaking in a voice that could not hide his arousal.
"She Burrows Into His Chest!"
Mike looked over his shoulder back at Jillian, waggling eyebrows that stuck out from the side of his face, almost like antennae.
"And..."
"Lays..."
"Her..."
"EGGS."
