Mark walked out of the bathroom after a long, relaxing shower. He looked up only to find Yugyeom sitting on his bed.
"Yugyeom!" He nearly dropped the towel, then remembered his nakedness and instead wrapped it halfway around his hips. "What the hell, man?"
"I heard you washing yourself and thought I would prepare you your clothing hyung," Yugyeom said as if it were the most normal thing in the world to want to dress your friend like a doll. "But, I can't find that black shirt you wore the last time I saw you. Is it not here hyung?"
"It's in the laundry bag, Jesus. Put that back, would you?" Mark gestured frantically to the anal beads Yugyeom held in his hand.
"Oh, yeah, what are these hyung? I meant to ask." Yugyeom examined the royal purple beads on their plastic string. "Is it a woman's necklace? How did you break it?" He cocked his head, clacking the beads through his fingers. Mark flushed at the sound.
"They're not a--oh my god, can we please not? You need to put those away right now, Yugyeom," Mark said, covering his red face with one hand, still holding up the towel with the other.
Yugyeom frowned. "Why are you so ashamed hyung? Do they hold some private purpose that you don't want me to know?"
"Yes, exactly," Mark sighed. "Now please just--"
"Oh!" Yugyeom sat up straighter, the beads laying across his flat palm. "They're for sexual pleasure aren't they hyung? Interesting."
"You son of a--" Mark made a desperate lunge for his favorite toy, but Yugyeom disappeared from the bed. And was instead standing right behind Mark, his breath on Mark's neck.
"You put these inside your body hyung," Yugyeom murmured, still sounding awed. "Does it feel good?"
"Yeah," Yugyeom admitted, half-turning. He tried to back away from the maknae--still no concept of personal fucking space after all this time--but the bed was in the way. He stood there, still dripping from his shower, while Yugyeom crowded up against him with the beads clutched in his hand.
"Can you show me hyung?" Yugyeom asked. "I'm so curious."
"Uh." Mark felt his dick cast its vote with a healthy twitch under his towel. But his dick was an idiot and what did it know? "Yugyeomie, it's kind of weird to do that sort of stuff, like, together."
"Oh, I wouldn't use them myself. I would just like to help you, if I could hyung." Yugyeom blinked his innocent brown eyes at Mark, and there was no way someone could look that innocent for real. Mark's legs felt watery, and he lowered himself to sit on the edge of the bed. Yugyeom just stood between his spread knees, contemplating the beads he held. "I would be very careful. And the members won't be back for hours."
"Hours?" Mark's voice cracked.
"Don't you want me to put these inside you Mark hyung?" Yugyeom asked. His voice sounded all matter-of-fact, but the words he was saying went straight to Mark's cock. "I would like to see them stuffed inside you, and your body taking them so greedily. Or would you prefer to do it yourself, like you always do alone hyung?" He leaned down and looked Mark in the eye, a cool other-worldly stare. "Will you let me Mark hyung?"
"I, um." Mark licked his lips. "O-okay."
The towel slid off Mark's lap and dropped to the floor. The GOT7 maknae kneeled down between his hyung's legs, eye level with his stiff cock. It was red and wet, fluid beading at the tip. Yugyeom lifted one of the purple anal beads to Mark's cock-slit, rubbing the smooth plastic through the wetness there. Mark threw his head back, falling onto his elbows.
