Sonic and Tails always had a brotherly relationship that went back to when they were kids. Sonic remembered one time when he was fourteen years old how he pulled a prank on the young Fox. Two years ago, after a morning of running, the young hedgehog came home to see Tails curled up on his couch fast asleep after working on his machines including the Tornado. "Heh, little fox fell asleep", he smirked to himself. Walking towards the couch, he put the sleeping fox on his back and carried him back to his home and to bed. He didn't mind doing this since Tails was like a little brother to him.
As Sonic entered Tails' room he tripped on a loose piece of wood and fell on the floor while Tails was thrown onto the bed. Surprisingly, the fox was still fast asleep. Rubbing his arm, Sonic was curious that he wasn't shaken up. As he looked down, he caught a glimpse of Tails' feet and instantly a mischievous thought popped into his head.
Grasping hold of the blankets, Sonic tucked Tails tight into the bed so he wouldn't be able to move while his feet were showing. Smirking, the blue hedgehog took hold of the laces on Tails' shoes and quickly untied them. After slipping them off, he took hold of the ends of Tails' white socks and slowly pulled them off revealing Tails' yellowish orange feet and toes. He unconsciously took a quick sniff of Tails' feet but found that they didn't smell; it was if he just washed them. Pulling up a chair to the end of the bed and taking his gloves off, the hedgehog used one finger to stroke Tails' right sole.
"Hehehehehehehehehehehehehehehheheheheheehheheheheheheheheheehe" Tails giggled as his foot twitched slightly from the touch.
Sonic smirked hearing him giggle as he always knew Tails' feet were so sensitive that the slightest tickle made him chuckle. Impishly, he took the shoelaces and tied Tails' big toes together so that he wouldn't be able to move his feet. The hedgehog then used both his index fingers to tickle his arches, "Tickle tickle tickle, tickle the little vulpine".
"Hahahahahahhahahahahahahaahahahhaahhahahahahahaahahahaha quit it hehehehehehehehehehehheheheheheheheheheheheheehehehe" Tails giggled once more in his sleep but couldn't do anything to stop the tickling.
"All you can do is sleep and laugh... and laugh", Sonic smirked as he kept stroking the fox's soles faster and faster, "You may have the fluffy fur the girls like but your feet are sooo much softer. Coochie coooochie coooo, tickle tickle tickle". He kept tickling the fox's arches using all his fingers this time.
"AAAAAAAAHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAA NOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHO", Tails laughed louder as he kept sleeping.
"Now for your delicate toes", he smirked and started tickling the undersides of his wiggling toes, "Aww they're softer than even your feet. Coochie cooochie coooooo".
"BWAAAAAHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHHAHAHAHAHHAHAHAHAHHAHAHAHAHHAHAHAHAHA CUT IT OHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOUT", he cried out laughing being shaken out from his sleep.
"Hey, Tails, old buddy, how are you", Sonic greeted him with his friendly smile while continuing to tickle Tails' wiggling toes before stroking in between them.
"WHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAAHHAAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAAHAHAHAHAHAHAHAHAHAHAAHAHA STAHAHAHAHAHAHHAHAHAHAHAHAHHAHAHAHAHHAHAHAHAHHAHAHAHHAHAHAHHAHAHAHAHAP TICKLING MEHEHEHEHEHHEHEHEHEHEHEHEHEHEHHEHEHEHEHEHEHEHHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEE", Tails pleaded continuing to burst with laughter.
"I'd like to but I must keep tickling your toes", Sonic smirked as he kept tickling the tips of each of his toes.
NOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHO AHAHAHAHAHHAHAHAHAHAHAHHAHAHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHA SONIC DON'T TICKLE THEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHHEHEHEHEHEHEHEHEHEHEHEHHEHEHEHEHEHEHEHEHEHEHEHHEHEHEEHEHERE", he cried with laughter as he tried curling his toes up to no avail.
After a while, Sonic stopped briefly to let Tails catch a breath. "Strange that your feet look so clean, Tails", Sonic said to his panting fox friend, "Do you wash them everyday".
"Well yeah... unlike you.... I care about.... my cleanliness", Tails panted. Sonic fumed at that, "You saying my feet stink?" Tails suddenly gulped realizing what he just said as Sonic began untying his shoes and pulled them off. Slipping off his white sweaty socks, he revealed his blue feet and toes while wiggling them.
"Oh no, Sonic tickle my feet if you must but anything but that", Tails pleaded. Sonic ignored this as he held his feet and wiggling toes at an inch length away from Tails' soles. "Please... have mercy", Tails begged. Sonic smirked as he instantly placed his sweaty soles against Tails' and wiggled his soles and toes all over Tails' feet.
"AAHHAHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHHAHAHAHAHAHAHAHA NOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHO NOT THE FOOTSIES HEHEHEHEHEHHEHEHEHEHEHEHEHEHHEHEHEHEHEHEHEHEHEHEHEHE I DON'T WAHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHANT MY FEET TO SMELL TOO", Tails burst out laughing.
"Your feet won't stink" Sonic smirked as he kept wiggling his toes against the fox's toes, "Besides this is fun". Sonic then wiggled his toes in between Tails' toes, "Getting every inch of your feet".
EHEHEHHEHEHEHEHEHEHEHEHEHHEHEHEHEHEHEHEHHEHEHEHEHEHEHEHEHEHHEHEHEHEHEHE STAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHAHAHAP PLEEEEEEEEEEEEEEEEEASE AAAAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHHAHAHAHAHHAHAHAHAHHAHAHAHHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAA", Tails kept laughing.
Sonic kept going until Tails fainted from laughing too loud. Oh how Sonic remembered that day. Unfortunately, that memory came at the worst possible convenience. At the present time, Sonic was strapped to a metal table and laughing his head off as two feathers kept tickling his bare feet at a high speed. At the controls was Tails smiling mischievously thinking to himself, "Definitely worth the two years wait".
