Rinko laughs in captivity

Rinko finds herself in trouble once again when she falls victim to a prank often pulled on freshmen, her classmates lured her to the garden, told her to undress as part of their little ritual and then tied her tied up to a horizontal pole, they proceeded to run away with her clothes and challenged her to break free and get them back. Ako walks in, she finds her friend bound and figures she too ended up getting pranked. "You should have told me about this, you idiot!" she complains, then Ako responds "Geez, calm down, I'm gonna get you out of- hmmm..." and Rinko gulps, already guessing what she thought about.

"You know, Rincchan, seeing you all tied up like this..." Ako says, "Don't you da-AAHAHAHEHEHEEEEE!." Rinko tries to protest, but it's too late, she could already feel her friend's sharp nails tickling her feet, immediately causing her to laugh out loud. "Oh wow, your feet are incredibly soft, it's so satisfying to touch them!" Ako exclaims as she increases the tickling's intensity. "N-no! Stop, leave my feet alone, you weirdo!" Rinko yells in the midst of her laugh to no avail, she laughs even harder when Ako starts to lick her foot. Ako then decides to give her feet some rest and move down where her upperbody was completely exposed. "Hi there!" she says excitedly, her enthusiasm is met with a panting Rinko saying "Fuck off..." before Ako then goes for her belly, which is completely vulnerable and curved forward due to the weight, Rinko tries to resist but eventually loses it.

"Hmm, oh yeah, don't think I forgot about your weak spot... here!" Ako moves her hand to Rinko's armpit and she screams out as her laugh gets even louder. "Hahaha, you're so sensitive here!" she laughs, Rinko pleads "Please stop! I can't handle this! Holy shit!" as she cackles and tries to move away from the tickling. "But I'm only tickling one armpit, you should be begging when I get both of them like this." Ako giggles as she then tickles both of Rinko's armpits, sending the poor girl into hysterics. "STOOOOOP! YOUR NAILS! THEY MAKE THIS EVEN WORSE!" Rinko cackles and begs, but Ako is reveling in this, saying "I know, that's the point, they're supposed to make the tickling worse." as she continues to torment her friend. After a few minutes, Ako lets Rinko rest, "I'm so gonna get you back for this..." the girl mumbles, Ako then says "Is that so? Do you want to tickle me back? Go ahead, then!" as she raises her arms, showing off her armpits. "I can't do that when I'm tied up, you dumbass!" Rinko responds, then Ako says "Oh yeah, true, but I can tickle you and you can't do anything about it..." lowering one of her arms and tickling Rinko's armpit with her index finger, which is already enough to make her go back to laughing out loud.
