Tease him to

Be smart, slut, this is a long game you are playing. With immense effort, Lunnara made her most annoyed and judgemental look as she crossed her arms over her chest. "How dare you!?" She berated the Dragon.

"Wha...?" He said, confused.

"Young man, don't you know that it is extremely rude to show your willy like this to a woman? I can't believe this! Such an irresponsibility! Is this how you pay me for being nice to you?"

"I'm sorry!... I didn't... I thought you had seen it already" He is right. Don't let him think about it.

"Do you thing that's an excuse for your behavior!?"

"It just hurts too much... and when I look at you... it goes like this... Please, don't get mad."

"I am deeply disappointed by this. You have betrayed my trust! I cannot express with words how humiliating this is for me."

"I'm sorry..."

"As you should!" She screamed in her most tsundere of tones, her eyes reddened as if she was about to cry. She turned around, arms crossed, giving her back to the dragon, and she took the light of her magic ball with her, to leave him in darkness. And now, wait.

"I'm sorry... I didn't know... really." He said with a low and meek voice.

Not yet.

"I just... I found you most pretty. You are incredibly beautiful and you have been so nice to me... and when I look at you my thing goes tingly..."

Not yet.

"Please, I don't want you to get mad and leave me here..."

Hold still...

"...Is there anything I can do?"

Bingo.

She turned back slowly, still with a judgemental look. "Your urges are your responsibility to contain, not mine."

"Ok..."

"If you show such thing to a woman you are asking her to take responsibility of it, and that is much to ask of a stranger. It is rude and immature."

"Sorry..."

"Silence, you have said 'sorry' enough times already. Saying it again won't matter much. Now, you had ask me already to take care of it for you. Do you understand the kind of predicament this put me in?"

"I guess..."

"I didn't ask about your guessing, young man. Do you know?

He lowered his head even more again. "...no"

Lunnara looked back at him in silence for almost a minute, letting him fear her answer. She lowered the light of her magic just a little, so the room grew more oppressive and black around them. She finally talked back, just before he started to tremble. "Well... next time you should know that your actions have consequences. Come here."
