They ended up fucking the entire night as well.
When the sun came up the next morning, Amon knew his body could still continue, but Tuang Yin looked very exhausted already. She was unlike Amon, after all. She still needed sleep like other normal people, but the girl continued being stubborn.
"Stop! We have wasted enough time as it is," Amon declared. "I consider this as repayment enough. Now, get off! I still have many things that need doing."
"Does this mean you concede?" Tuang Yin asked.
Amon stared at her without saying anything.
"I'm just joking! Fine, fine," She rose and let Amon's penis go. "Damn! it's still so hard!" She exclaimed and slapped the erect rod.
Amon ignored her and went to clean himself with a bath. Despite being very tired, Tuang Yin chased after him and joined him in the bath.
"Hey, maybe we should learn the dual-cultivation art! Since we are going to do this often," Tuang Yin said while their bodies were rinsed by running water.
