"Ryouma-nii-san! Shinonome! Please, my holes are starting to ache..." A naked Kamui gasped as her breasts bounced around from the thrusting from the two men close to her. "I'm going to go crazy..." She couldn't believe they just dragged her off to her room and decided to fuck off without even considering her opinion on the matter...

"Don't complain, Kamui! This is a test to see who is worthy of being close to you!" Ryouma boomed, his cock scraping her asshole.

"Yes, I will be the one to surpass father!" Shinonome grunted as he slammed his dick into his mother's wet pussy.

The two men kept pounding and ravaging their sister/mother's holes, hoping they'd cum before the other. "This doesn't have to be-aaaaahhh!" Kamui felt Shinonome's cock tense up as he shot off a round deep into her waiting womb. "Oh, gods!" She gasped out as Ryouma released his own cum into her ass, panting her insides white.

"I have won, father! I am worthy!" Ryouma's son shouted victoriously as his father growled in defeat.

"Ughhhh..." Kamui went limp onto Ryouma's chest as she let out a moan, her glazed eyes staring at a laughing Shinonome.
