Seojin said he was going to invite Seojun to join them but he was just going to carry on until Seojun eventually walked in.
They kissed and made out quite loudly.
Seojin laid Dongwoo on the bed and took off his shirt, trailing kisses down his neck, and then landed on his chest.
He sucked on Dongwoo's nipples hard while stroking Dongwoo's dick.
Dongwoo squinted his eyes, feeling too much stimulation from his nipples and then his dick. His body tingled and twitched.
"Haah! Ah! You shouldn't... You shouldn't do that." Dongwoo said, panting. "You shouldn't do just... Ahn! Ah! Just that."
"Hm? What do you want me to do then, Hyung?" Seojin asked. "Tell me and I'll do anything. I want to explore all of your sweet spots and make you feel good."
"Th-then," Dongwoo looked away, shy as he widened his legs and spread his hole. "Put it in. It... It'll make me feel really good if you... If you hit that spot I really like."
Take it from me, your creator, you're all pervert. you better deal with it or deal with it, hmph!
And as for that last part, it's about to go downnnn!
