"Mom, you know how much I hate this bullshit head, right?" Beomgyu asked with his hand on his hips, Mrs. Kang sighed disappointedly and shake his head.
"If you want to eat your favorite food then you must stay here and wait for us to come back, stop being a badass son, we're going now okay? Take care of Taehyun." and the door shuts close.
Beomgyu glared at the door before locking it and turned around to Taehyun who sat on the couch with his back leaning on the headboard.

"Stop, you call me bullshit earlier in front of mom." Taehyun said as he pushes Beomgyu away.
"I'm just doing that to make it more convincing, aish why couldn't you understand it?" Beomgyu shoves Taehyun's hands away and grinds his buttocks on the blonde's pants again.
"But still you call me 'bullshit' but anyways, you said you want to relax?" Taehyun asked, Beomgyu stopped grinding and cheekily smiled.
Taehyun and Beomgyu were now at the bathroom, making out.

"Wait---I'm c-cumming" Beomgyu warned, "Cum for me, kitten" Beomgyu's mouth was open as if he was moaning, his eyes were closed, and his cheeks were tinted pink.
In three beats, Beomgyu cum between his and Taehyun's stomach, Taehyun also followed after four beats.
They both close their eyes and pant heavily.
"How's is it little kitten?" Taehyun asked, Beomgyu open his lustful eyes and smiled for the response.
"My kitten always wants to play, Master's back was full of scratches, do you know what does it mean?" Taehyun lifts his chin and stared directly at his eyes.
"It means kitten will get punishment later," Beomgyu answered as he leaned to kiss Taehyun, but...
"No, no kitten, you can get your kiss later, we have to clean ourselves before our parents come back home." Beomgyu groaned and pull Taehyun away from him.
"Uhm why does it smells like...Uhm.....weird...like sperm?" Mrs. Kang asked, she's been smelling this before until right now and he is curious about it.
"What do you mean, Honey?" Mr. Kang approached her and put his hands on her shoulder.
"Nothing maybe I mistook it." Mrs. Kang said and continued slicing the carrots.
