Marin has been on Moira's radar ever since she stumbled upon some cosplay pictures of her, with Ako's help she managed to get in contact with Marin and she ended up agreeing to shoot a tickle torture video for Moira's site. After an interview where Marin said her upperbody in general is very ticklish, especially her armpits, Moira put her on a device that could properly stretch her victim, leaving the upperbody completely exposed.
"Hey, gorgeous." Moira teases her, gently caressing her cheek. "What are you doing here?" she asks as her index finger slides under Marin's chin, giving her goosebumps. "N-nothing much. And you?" she says, giggling as she looks at Moira's hand. "What? Are you nervous? Here, let me help you relax and laugh a little..." she says as she slides her finger against Marin's armpit, causing the girl to flinch as she tries to hold back her laugh. "What is it, my dear? Why are you trying not to laugh? Come on, I wanna hear it~" Moira then starts to use both full hands to tickle Marin's armpits, causing her to almost instantly burst out laughing. "Kyahahaha, wahahait! Please, stop!" she tries to plead, Moira's rapid-moving fingers combined with her long nails proves to be way more torturous than Marin expected. "Haha, what do you mean stop? I'm just getting started!" she responds as she moves one hand down to squeeze Marin's left rib, causing her to yell loudly.
"Hmm, so that sexy tummy of yours is sensitive too, let's play with it a little~" Moira then gets behind Marin and starts attacking her sides before she can protest it. "N-no! It's not ticklish, I promise you it's NOHOOOT- AHAHAHAHAHA!" Marin laughs out loud and starts to squirm left and right as Moira keeps scribbling around her belly. "What about your bellybutton?" she asks as Marin's eyebrows raise, she doesn't even try to argue as she knows Moira will go there anyway. "BAHAHAHAHAHA, SHIT! IT TICKLES SO MUHUHUHUCH!" she cries out as Moira continues to dig in her navel, giggling in amusement.
"AHAHAHAHEEHEHEHEEEEE! NOOOOOO!" Marin desperately screams as Moira goes back to tickling her armpits. "Yeeees, your armpits are so smooth and satisfying to touch, I could do this allll day~" Moira licks her lips, not letting Marin's armpits rest even for a second. "GAHAHAHA- SHIT, GET OFF MEHEHEHEEE! I DON'T WANNA- HIHIHIHI! D-DO THIS ANYMORE!" she begs, Moira laughs at her predicament. "Oh come on, look at your social media pics, you're always showing off your armpits and your cosplay picks are always wearing some suspiciously revealing outfits, you were totally asking for this!" she argues, but Marin is laughing way too hard to properly respond. "I wonder what your armpit tastes like, though..." she says, moving her face closer, much to Marin's desperation. "N-no, it tastes horrible, seriously, you're not gonna like it, please don't- EEEEEK! KYAHAHAHAHAHAHAAAAA!" Marin's desperate pleads fall on deaf ears as Moira licks and sucks on her armpit, she cackles hysterically. "Mmmm, delicious~" she continues, but not before using her free hands to tickle Marin's other armpit. "Your girlfriend is the luckiest girl alive, she can do this to you every day, I envy her~" Moira says in between the licking, Marin blushes and responds in the midst of her laugh "She- hahahahaha! She does this a lohohohot!" her words are confirmed by Nagatoro, who is watching from behind the scenes and proudly says "Yup, wrestling Marin down and tickling her is one of my favorite pastimes!"
As Moira lets Marin rest for a while, she returns with a pair of feathers in her hands. "Do you like these?" Marin shakes her head in response to Moira's question, "I don't like them at all- GAHAHAHAHAHA!" the feathers prove to be surprisingly effective, she's laughing even harder than before. "Haha, so you're feather-sensitive, that's so cute!" she laughs and slides the feathers all over Marin's armpits and belly. "It's not cute! Bahahahaha! It's not cute at all!" she argues back, her body squirming around trying to move away from the feathers to no avail. "It is." Moira says, "It's not!" Marin pouts, "It iiiis~" Moira then proceeds to move the feathers exclusively to Marin's armpits, she laughs desperately and yells "KYAAAAA! OKAY, IT IS! HAHAHAHAHA! IT IS, STOP MOVING THAT DAMN FEATHER PLEASE!"
"Alright, no more feathers then." Moira says, putting the feathers away but then going back to tickling Marin's armpits with her hands. "AHAHAHAHAHAHAHA! SHIT, STOP! STAHAHAHAHAAAAAAA!" her desperation is met with Moira playing dumb. "What? You told me to stop using the feathers, I'm not using them anymore. You're really hard to please, huh?" she asks, Marin tries to respond "I DIDN'T- HIHIHIHIHI! I DIDN'T TELL YOU TO- AHAHAHAHAHAHAHA! TO KEEP DOING IT WITH YOUR HANDS!" and Moira laughs at her. Suddenly, Nagatoro picks the feathers back and walks in the scene. "Oh hi there, wanna join in?" Moira's gentle tone heavily contrasts with the torture she's putting Marin through. "Yeah, also I have a really good spot in mind for these, if you excuse me~" Nagatoro then cuts off Marin's bra, revealing her breasts. "N-NO, NONONONO, PLEASE HONEY DON'T! GAAAAAH, HAYASEEEEEEEE!" she laughs hysterically as Nagatoro slides the feathers around her breasts, rubbing them harder against her nipples. "Hahaha wow, you even called me Hayase, you only do that when you're mad at me!" she laughs. "I AM MAD AT YOU RIGHT NOW- HAHAHAHAHA! SHIT! OH GOD, I CAN'T HANDLE THIS, STOP, YOU TWO! I GIVE IN!" she gasps for air as the two grin and continue to tickle her. "Just a bit more, I'm gonna miss touching these pits once we're done here~" Moira teases her as the session goes on for a few more minutes until Marin is completely exhausted.
