Nagatoro successfully ambushed

Marin always finds herself on the receiving end of her tickle fights with Nagatoro, mainly because while she is very ticklish, she's also quite strong and her Judo background ensures that she's very efficient at immobilizing Marin and tickling her to her heart's content. So, when they end up hanging out with Tomo and Gamo, Marin sees this as the perfect opportunity to get her girlfriend good and has Gamo challenge her to a little match on the couch, which Nagatoro agrees and the two begin their little spar, which is soon interrupted by Tomo grabbing nagatoro's arms and pushing them, keeping her upperbody stretched while Gamo grins and grabs her legs.

"Hey, what the hell is going on here? Let me go!" her demands are ignored as Marin steps in. "Oooh, look what we have here, my girlfriend is totally helpless in this situation..." she says as she traces Nagatoro's tummy with her fingers. "Y-yeah, so be a good girl and help me out he-ehehehehe, hey! Knock it off!" she tries to respond, but once Marin applies a bit more pressure to her scratches, she immediately giggles and struggles against the two girls keeping her like this. "Nah, I don't feel like being a good girl right now, especially since you have been pretty naughty to me recently~" Marin tickles her tummy while moving her index finger to her armpit. "N-no, that's not- bahahahahaha! Nooooo! Not there!" she laughs harder once Marin's index finger starts to ding into her armpit."Not here, you say?" she immediately starts using her full hand to tickle her armpit, causing Nagatoro to laugh loudly and struggle more desperately. "AHAHAHAHAHAHA STOP! HOLY SHIT, LET ME GOHOHOHOHOOOO!" she begs for Tomo, who simply shakes her head and continues to hold her arms, being much stronger physically, she ensures that Nagatoro won't be breaking free anytime soon, Gamo is not exactly stronger, but she got her legs locked in a pretty good position and laughs in amusement.

"Honey, I have a theory that maybe your other armpit is about as ticklish as this one, would you mind if I test it?" her question is immediately answered "Yehehehes, I would mind it very much-AAAAAHAHAHAHAHAA!" but Marin doesn't care and goes for both armpits, sending her girlfriend into a hysterical laughing fit."HAHAHAHAHAHA! FUCKING STAHAHAHAHAHA! EHEHEHEHEEEEEE!" she pleads, swears, squirms, but nothing works and Marin keeps relentlessly tickling her armpits. "Hehehehe look, she's even drooling!" they laugh as Marin points out, she continues to tickle Nagatoro's armpits for a few more minutes before letting her rest a little.

"Uhhhh... no more... please..." she begs, her voice sounding weaker as she catches her breath and recovers from the dizzyness after this intense laughter. However, Marin instead starts to blow raspberries on her tummy, catching her off-guard, "Sorry, I couldn't resist, your belly is so vulnerable like this~" she says as she blows another one, Nagatoro laughs and yells "Enoooough!" but Marin insted just started to lick her navel, which actually tickles her more than the raspberries."NOOOOO, GET OUT OF THEHEHEHEHEERE!" her reaction causes Marin to grin as she then moves back up. "Alright then, I'll just lick your armpit instead~" and Nagatoro's attempt at yelling "NO!" is immediately cut off by her cackling as Marin licks one armpit while using her hands to tickle her tummy and her other armpit.

"You know, I wanna tickle her too. What do you think, Gamo?" Tomo asks, her friend nods. "Yeah, I think we deserve our share of the reward for this..." much to Nagatoro's desperation, Marin agrees and stops tickling her for a while, letting the two wrestle her down and continue the torture session. As Marin watches from the couch, she couldn't help but use her feet to help them a little.
