Ch 1
Azula approached Aang's house, remembering she was there to continue her private lessons with Aang. Though she knew this lesson would be different than their regular yoga lessons.
'You want to do what?' Aang asked.
'Some S&M roleplay. Maybe throw in some ballbusting.' Azula replied.
Knocking on the door, she saw Aang open up and usher her in.
"So how do you want to proceed with this?" Aang asked, closing the door after Azula. No sooner than he turned around than Azula suddenly threw a kick between his legs as hard as she could.
Azula smiled and laughed as Aang could only groan in pain, gingerly holding his balls.
"You could have at least warned me." Aang said.
"I prefer a quick and sudden strike. And to answer your first question, this is how we're proceeding. We're both naked, and i get to punish your genitals as i see fit." Azula said.
Aang took several deep breaths before standing up making sure to keep his legs as closed as possible. The pair headed to the bedroom and proceeded to strip nude.
"Wow. You're beautiful Azula." Aang said, pulling his student close to him. The two gently kissed, their hands on each other's bodies.
Azula pushed Aang onto his bottom in front of his bed, then pulled his legs apart and tied them to the bed posts, along with his arms.
"I'm liking this. What next?" Aang eagerly asked.
Azula didn't respond, but instead stomped on Aang's nuts as hard as she could. Aang cried out in pain as she began to grind her foot against the floor, his sac caught between them.
"Please, stop!" Aang exclaimed, hoping for some mercy.
Azula stopped and walked closer to Aang, towering over him. Aang looked up at Azula, knowing she was in the dominant position. But Aang would lie if he said that wasn't a turn on. Azula felt something rubbing against her foot, and she looked down seeing his erection.
"So, my teacher likes being the submissive one. Good." Azula said, putting her foot on his penis and pressed down hard against the floor. Aang pulled Azula on top of him putting his tongue inside her core, licking her moist flesh. Azula held Aang's head in place as she rocked her hips back and forth.
"Spirits, Aang. You know how to please a woman. Have you done this before?" Azula asked.
Aang muffled out an answer, only to have Azula kick him in the nuts again.
"How long are you going to bust my balls?" Aang weakly asked.
"Until i get bored." Azula said, untying Aang. She forced him on his knees and continued her session, kicking Aang between his legs until he threw up.
"So, how did you enjoy it?" Azula asked. Aang couldn't answer, only giving out a weak moan in pain. Azula left the room and soon returned with an ice pack.
"I may need to see a doctor." Aang said putting the ice on his nuts.
At the hospital, Azula watched as Aang was taken in for a checkup. Hearing her name called, Azula turned to see Ty Lee walk in.
"I got your message. You said it was important." the acrobat said.
"It is. Ty Lee, i screwed up." Azula said, before going into details about the night.
Ty Lee could only look at Azula in shock, then anger filled her face.
"What the hell's the matter with you?! If you kicked him hard enough to make him throw up, who knows what you may have done to him. He may need surgery! Is that what you wanted?" Ty Lee angrily asked.
"No, that's not what i wanted. It just got out of hand." Azula said, trying to calm her friend down.
"Out of hand? I know you two are close. If you wanted to have kids with him, you can kiss that opportunity goodbye." Ty Lee said.
A doctor approached Azula and pulled her aside.
"Azula, i'm doctor Katara. Aang is…" Katara started when Azula interrupted her.
"How is he?" Azula quickly asked.
Katara glared at Azula in response.
"Aang is fine. He'll be sore for the next few days. Just keep him comfortable for the time being. And try not to hit him in the nuts." Katara said.
