[Request] A slumber party filled with laughs

As Takagi and Marin are spend the night at Ako's home, they play a card game where the loser would end up being tickled by the other two players. Upon losing the game, Takagi tries to run away but Marin closes the door and Ako quickly grabs her and wrestles her down with her armpits exposed. "W-wait, WAAAAHAHAHAHAAA!" the girl lets out a loud laugh even when Ako just slides her index finger against her armpit, "Oh wow, I didn't know you were THAT sensitive, so cuuute!" Ako says as she continues to tease and tickle Takagi's armpit, giving it a few scratches with one or two fingers, "Alright, time to start tickling you for real now!" she says as she now uses her full hand, Takagi screams and laughs hysterically, desperately trying to break free from Ako's hold, but it's no use. "Hahaha, seems like you alone is already too much for her to handle. Should I join in?" Marin says, then she jumps right in "Of course I should!" and Takagi laughs even harder with the two hands now flocking on her armpit,completely overwhelming the poor girl.
