Being Yuu's girlfriend is not an easy task, she doesn't just have a tickle fetish, she can be downright evil when she gets to torture Tomoko in their intimate moments. Yuu is very well aware of how sensitive her girlfriend is pretty much everywhere, yet she loves pushing the poor girl to her absolute limits, getting her to laugh until she's almost out of breath and making her beg for mercy before the session stops. They arrive at the SM room, taking a good look at the devices to place Tomoko in until they find just the right one.
"So, pretty much your entire body is extremely sensitive, but I noticed your armpits and your feet are the areas where you laugh the hardest when I get my hands on them. This one should do the trick, then!" Yuu says as she puts Tomoko in the device, her arms tightly bound above her head, and then she opens up a compartment that exposes her feet.
"I'm kinda starting to regret- aaah! H-hehehehey! Don't just start without a warning like that! Bahahahaha!" Tomoko's thoughts are interrupted as she immediately feels Yuu's hands scratching her foot. "You whine too much, Tomoko, it's not even that bad..." Yuu's response causes Tomoko to laugh harder as she increases the speed of her fingers' movement. "Hahahaha- shut up, you're not- aheheheheheeeee! You're not the one being tickled!" she tries to argue back, but this is only met with Yuu tickling both of her feet, sending her into a laughing fit. "Sorry, what was that? Can you repeat what you just said for me? I was too hypnotized by your feet to listen." Yuu grins as she continues to tickle Tomoko's feet, the girl cackles and tries to move them away with whatever little mobility they have in that device "STOOOOP! GODDAMMEEHEHEHEET! LEAVE MY FEET ALONE!" she yells in the midst of her laugh and for a while she's relieved that Yuu stopped and takes the time to catch her breath.
Then suddenly, Yuu's hands show up from above her. "Okay, as you requested, I'm leaving your feet alone." she says as Tomoko nervously giggles in anticipation as her hands approach her armpits. Even a slight touch in that area is enough to send Tomoko into hysterics, but Yuu went all-out from the start, Tomoko's hysterical laughter echoes throughout the room. "NOOOOOOO! STOP, PLEASE! I CAN'T HANDLE THIS!" she yells, Yuu laughs at her desperation and continues to wreak havoc on her exposed armpits. "Whaaaat? You told me to leave your feet alone, I'm no longer tickling them, what's the issue now?" she plays dumb as Tomoko tries desperately to break free, but she can just barely move in that device. "BAHAHAHAHA, STOP TICKLING ME IN GENERAL, DAMMEEEEHEHEEET!" she lets out a protest, Yuu laughs and responds "No can do, honey. Any other request?" as Tomoko's laugh starts to be followed by gasps. "Please, you're going too hard on meeeee!" Tomoko whines, barely having the strength to yell, Yuu stops temporarily.
"Haaa... haaa... holy shEEHEHEHEEET!" her breather is interrupted when Yuu starts to poke her left armpit. "What? Are you telling me even some light poking gets that strong a reaction out of you?" Yuu giggles as she keeps poking her girlfriend. "IT STILL TICKLES LIKE HELL, STOP!" her pleading causes Yuu to grin. "Sooo... if it's gonna tickle you a lot anyway, then I might as well just use my full hands." she says as she licks her lips and tickles Tomoko's left armpit with both hands, sending the girl into a frenzy. "BAHAHAHAHA FUCK! IT TICKLES HIHIHIHI IT TICKLES SO MUHUHUHUHUCH!" Yuu seems happy with that as she continues, teasing Tomoko while she's at it. "Aww, do you wanna pull that arm down?" her question is met with Tomoko angrily yelling "OF COURSE I DO, YOU IDIOT!" but that only made Yuu tickle her armpit harder. "You're so mean to me, Tomoko! I'm here making you laugh and you call me an idiot!" she grins as Tomoko keeps laughing and begging, trying her hardest to move away to the other side.
After letting Tomoko rest for a few seconds, Yuu suddenly tickles her right armpit now. "Come on- hihihihihihi! Aren't you satisfied yet?" she complains, Yuu shakes her head. "What? I'm just gently sliding my finger here, how is this even supposed to tickle?" she asks as her finger scribbles the center of Tomoko's armpit. "It just dohohohoooes!" her answer makes Yuu giggle as the girl then proceeds to lick her armpit. "N-NO! ANYTHING BUT THAT!" her immediate response makes Yuu laugh as she licks her a bit more and then concludes "You know what? You complain too much, so back to using the full hands it is!" and before Tomoko can protest she goes back to tickling both of her armpits."BAHAHAHAHAHA! NOOOOOO! SOMEONE- HEHEHEHEHEEEEEE! SOMEONE HEEELP!" her screams, unfortunately, aren't audble for people outside of the SM room.
"Yuu-chan, are you here?" Mikazuki enters the room and stumbles upon the scene, unsure if she should interrupt it or not, but then she sees Tomoko's feet wiggling from the other end of the device and couldn't hold back from tickling them. "WHAT THE- AHAHAHAHAHA! WHO'S THERE ON MY FEET?!" Tomoko tries to see what's going on there, but Yuu then pouts and says "So not only are you complaining all the time about our little moment, but now you're interested in seeing another girl too?" as she tickles her armpits even harder now. After the two have their fun with Tomoko for a few more minutes, she starts to cough, unable to even laugh any longer and starts to beg "Please... stop... I can't take this any longer..." as if she was about to pass out, they stop and let her catch her breath.
"Mikazuki-chan... you little pest..." Tomoko says, agrily staring at Mikazuki while Yuu pats her head. "Hehe, good girl, you did very well~" she seems happy upon hearing Yuu's words. "Hmph..." Tomoko scoffs, seemingly jealous, but Yuu then plants a kiss on her cheek, saying "And now to the best girl in the entire world~" which causes Tomoko to blush as a smile forms on her face despite her trying to hide it.
