Sawatari practically dragged Yuya up to his room the moment they got to his house, barely giving the two of them enough time to take off their shoes. Yuya blushed a little at his friend's enthusiasm, following closely behind him. As soon as they got to Sawatari's bedroom, the boy locked the door behind them so that the house staff couldn't walk in.
"C'mon! My bed is super comfortable! You can lay on it while I tickle you!" Sawatari said eagerly, pushing Yuya toward the bed.
Yuya blushed brightly and lay down on the bed. It really was super comfortable. Sawatari smiled, clearly waiting for Yuya's input on the bed. The tomato smiled and relaxed onto it. "It really is comfy!"
"Of course it is!" Sawatari said proudly. "Hey, do you mind if I tie you up a bit?" Yuya's face resembled his red hair at the question, but he smiled. "Yeah, go ahead!"
Sawatari beamed and went to his dresser, pulling out a few ties. He used to wear them with his school uniform, but he'd swapped them out for a cool necklace he bought after seeing Yuya's pendulum when they first met. He'd wanted to impress Yuya with his own necklace, but Yuya never seemed to notice that he was wearing it.
Yuya blinked a little when he saw the ties. "You still have those?" he asked. Sawatari looked at him in confusion. "What do you mean?"
"Well, I remember when we first met, you were wearing a tie, but the second time we met you were wearing your necklace instead, and I haven't seen you wearing a tie since?" Yuya said. Sawatari beamed. "So you do notice my necklace!"
"Yeah, it's really pretty! I like it!" Yuya said. Sawatari beamed brighter, delighted to finally know that Yuya was impressed with the necklace. The taller boy was practically purring as he used his ties to tie Yuya to the bed spread-eagle. Then, he gently stroked Yuya's armpits.
Yuya's reaction was instantaneous. He started giggling and squirming. "Heeheeheeheeheehee! Sahahahawahahahatahahaharihihihihi! Hahahahahaha!" Sawatari grinned at the tomato's cute giggles. "You're so sensitive! I've barely even begun and you're already such a giggly mess!" he teased.
Yuya blushed at the teasing. "Ihihihihit tihihihihickles! Heeheeheeheehee! Hahahahahahaha!" Sawatari just chuckled and slowly started tickling down to Yuya's ribs. "Where are you most ticklish, Yuya?"
"Myhyhyhyhy feeheeheeheeheeheet!" Yuya giggled. Sawatari smiled. "I'll save those for last then!" Yuya's toes curled and uncurled in anticipation as Sawatari slowly tickled down to his tummy. The taller boy lifted up Yuya's shirt and leaned down, blowing a raspberry directly onto his belly button.
"EEHEEHEEHEEHEEHEEHEE!" Yuya squealed, thrashing around. "NAHAHAHAHAHA! NOHOHOHOT THE RAHAHAHAHAHASPBERRIEHIEHIEHIEHIEHIES! HAHAHAHAHAHA! ANYHYHYHYHYTHING BUT THAHAHAHAHAHAT! EEHEEHEEHEEHEEHEEHEEHEEHEE!"
Sawatari grinned. "You're even more ticklish than I imagined!" he said, before blowing more raspberries against Yuya's belly button. The tomato could see Yugo's spirit nearby, squirming a bit as he watched. All four of the counterparts were equally ticklish, though their death spots were all different. Yuya's death spot was his feet, Yuto's was his armpits, Yuri's was his sides and ribs, and Yugo's was his tummy and belly button. Seeing Yuya's belly button being tickled mercilessly was having an effect on Yugo, and the blunana was trying not to giggle himself.
Eventually Sawatari seemed to grow bored of tickling Yuya's belly, and moved down to Yuya's feet. He had barely even touched the tomato's socked sole when Yuya shrieked with laughter. "WAIHAIHAIHAIHAIT! NAHAHAHAHAHA! EEHEEHEEHEEHEEHEE!"
Sawatari giggled. "Wow, your feet are REALLY ticklish, aren't they? I've barely touched them! Hmm, let's get these socks out of the way, shall we?"
He began pulling Yuya's socks off slowly. Yuya's toes instinctively curled up, trying not to lose what little protection they had from the socks, but it was futile. Sawatari pulled the socks off and gently pulled the toes on Yuya's left foot back with one hand, slowly dragging a finger up the smaller boy's sole.
"HAHAHAHAHAHAHA! NAHAHAHAHAHA! SAHAHAHAWAHAHATAHAHAHARIHIHIHIHI! NAHAHAHAHA! EEHEEHEEHEEHEEHEEHEE!" Yuya screamed with laughter, thrashing around desperately. Tears were streaming down his cheeks, and his face was redder than his hair.
"Aw, this is so much fun!" Sawatari cooed. "You look adorable like this! Maybe we should do this more often!"
Yuya was laughing too hard to reply, but he liked the suggestion. He really enjoyed being tickled, and Sawatari was very good at tickling. This was a lot of fun!
