Some things to note before this gets started. These characters come from a world I have built. So there will be some references to characters you might not get. But as I post more stories some things might get revealed.

Nikhil was sitting in his dorm studying, it was late at night and the library was mostly asleep. The sounds of the sleepless and night owls didn't reach the private quarters of the members. So it was surprising to hear a knock on his door. When he got up to go open the door he would see Yalesh standing behind it in a nightdress.

She smiled softly and quickly signed "May I come in?" Nikhil a little shocked still stepped aside and gave her a nod.

As she entered she looked around and turned around to face him signing as the door was shut. "Why don't you have animals here?" Nikhil returned her singing with

"Qrow wouldn't let me bring animals to the dorm". She seemed confused as she returned the sign for Qrow. A sign made by curling your thumb, index, and middle finger into a claw. Nikhil would realize he's never used the sign to refer to Qrow so he quickly ran to his desk and wrote Qrow's name down. Showing her the paper as he redid the sign.

She nodded and signed to him "Me and Kesper use bird for them", Kesper was signed by putting your thumb between your index and middle finger to give them the rough shape of a star. Given since he's apparently named after a star. It made sense to use the sign for bird but the claw felt more fitting to their personality Nikhil thought.

"Wait! Why are you here?" He meant to ask earlier but got too caught up explaining the Qrow thing.

"You said I can come visit you whenever I want" He did say that but he figured she would come at more reasonable hours. She looked over at his desk and smiled,

"Studying biology?"

"Yes! Qrow is making me do my first test tomorrow"

"Sit down I can give you a personal lesson about humanoid biology" a smirk went across her face but Nikhil was just excited to get a free lesson so he sat down after Yalesh pulled the chair out. She got on her knees in front of him her hands reaching up to pull down his pants.

Nikhil looked confused and signed "Do I need to be naked for the lesson?" She nodded and Nikhil happily helped her strip him. He wasn't hard yet, mainly because he didn't know he was supposed to be hard. And Yalesh thought he was playing dumb to be cute. So when her hands wrapped around his dick and started to stroke he was more than shocked. But it was a new feeling this sense of pleasure that ripped through him. He didn't want to complain or ask her to stop, so she continued feeling him get harder in her hands. Once he was fully erect she moved to only having one hand on. Instead leaning in to kiss the head of his dick, before pushing her tongue out and taking the first half into her mouth. She gently wrapped her tongue around it and bobbed her head as she stroked his shaft. Nikhil was overwhelmed immediately unable to contain his moans as this private lesson continued. He didn't last very long either, as soon as Yalesh started to taste his precum she let go pushing her entire head down so his dick forced her throat open. His brain going blank as the cum left his body, completely unaware for a moment as Yalesh pulled her mouth away. Opening it for him to show she swallowed every drop of it.

"Did you enjoy your lesson?" She signed

He was barely able to give a nod in response as she got up to give him a kiss on the cheek.

"Rest up and if you pass your test I'll be back to give you more lessons."
