Seojin did not expect Seojun to pull a fast one like that. Well, it wasn't like they were going to do the old, 'rock paper, scissors' to know who would go the first round with Dongwoo.
"Who would've thought you would play a fast one?" He clapped his hands. "Well played."
"I couldn't hold it in." He said, brushing the back of his neck. "I got too excited. Sorry."
"Well, it's no big deal." He said and turned to look at Dongwoo, still twitching. "Hyung, you did quite well. You didn't even need to use the safe word. I'm proud of you." He said, smiling brightly.
And though Dongwoo could not see because the blindfold was still intact, he could tell just how brightly Seojin was smiling.
"T-thank you." He said, still panting softly.
"Then, are you ready for your reward?" He asked, his smile turning into a grin.
