Ako's revenge

The night after the Halloween Festival, Ako invited Marin and Mai to rest at her place since it's closer to the school and everyone was very tired by the end. However, despite her apparent kindness towards them, Ako was actually plotting to get back at them for the whole dancer-trapped-by-succubi thing they pulled on her. So, as they got ready to change their clothes, Ako had her sister Riko help with wrestling the two down and tying them up on the bed, then she leaves the two of them to Ako.

"So... did you two really think you'd get away with that funny business back at the festival?" they gulp as Ako lays between them. "Uhh... it was her idea!" Mai immediately spill the beans, "What? But you agreed with it instantly when I suggested that!" Marin retorts. Ako is amused with their bickering "Well, in that case..." she then starts to tickle Mai, much to her surprise. "Ahahahahaeheeee! I said it was her idea! Why are you tickling meeee?!" she asks desperately "Mai-senpai, that's no good... you're a terrible partner-in-crime if your first reaction upon being captured is to turn your friend in, you deserve some punishment for that..." Ako responds and Mai tries to think of a comeback but she's already rendered incapable of speaking from laughing too hard as Ako tickles her very intensely from the get-go, showing no mercy at all.

"Yeah, get that traitor, Ako! Don't let her rest even for a second!" Marin's cheering is heard as Ako then turns to her and says "Who do you think you are, giving me orders like that?" as she then tickles Marin's armpit while continuing to give Mai hell, the two laugh out loud. Then, Ako gets off Mai and decides to give Marin her full attention. "You didn't deny that was your idea, did you?" Ako's question makes Marin gulp, "W-wait, I can explaAAAAHAHAHAHAAAAA!" her armpits are immediately assaulted by Ako's wiggling fingers before she can even respond."I don't need no explanation, only the sound of your desperate laughter can satisfy me now!" she says, laughing diabolically as she doubles down on Marin's torture. "Your bellybutton is also pretty sensitive, right? I wonder if you're more ticklish here or there..." she says while tickling Marin's bellybutton and armpit at the same time, causing her to laugh hysterically.

"But be honest, Ako, you did enjoy it back then, right?" Mai asks as she recovers herself, her question is met with Ako grinning and moving above the two, she then tickle both of them at the same time before responding. "Yeah, you're not wrong, I do love being tickled, but even so... I love tickling a lot more~" she says as she continues to tickle her victims' armpits, the two laughing, begging and desperately trying to lower their arms with no success at all.
