Good to the bone

"Hey, Iris... could we... talk?" She saw you already and walks right up to you and crosses her arms: "I hate you. Sure." She must've lost her little bit of nervousness already and you can't help but blush. "Yeah... so... ah, I don't know what to say..." You say embarrassed and she leans on the table and says calmly: "Whatever. There's a big thing I need your help with, ASAP. The party's almost over, and I was tasked to set up the finale. It's quite the pain in the ass to do all by myself. Wanna lend me a hand?"

You smile and nod, she nods and says while looking at you almost casually: "Ok, the special event this year. It was mine and Chels' idea, so bear with me... We call it the: "Scareathon" like... you know, 'scare a ton', get it? I know, stupid fucking name, anyways..." You listen smiling and she continues: "Basically I went and rented us these heartbeat meters and you just attach it on the wrist and it tells you how close you are to shitting your pants... or... underwear I guess..." She looks at your dress and you laugh just a little.

"Y-yeah... and the twist is that if you get too scared you will get a little stimulation. This is a goddamn sex party, ok? And this comes from Chelsie, not me. I came up with the pulse meter, she came up with the vibrators, s-so that you know..." She takes her fan out and you are starting to see what it's about. "Ooh... really? Wow..." You imagine it and it almost feels unreal. "But doesn't like... getting turned on also raise your heart beat? Isn't that like a... big flaw there?" The skeleton shrugs and says calmly: "Whatever. If you get horny, that's on you. The one who can last the longest wins the whole thing. And she gets the ultimate prize. Guess what it is?"

You have an idea: "Is it to get on Chels' VIP?" She nods and sighs: "Stupid fucking prize I think, I just bought them some gift cards for some designer stores. So yeah. I'm not participating, neither are the sisters. You can if you want. I won't hold it against you or anything..." You feel a little nervous, getting horny from a vibrator sounds weird and perverted especially in the middle of everyone else. "So... how do you get scared then? It isn't honestly that scary just here normally..." You ask and the skeleton girl listens closely: "Yeah, that's the... fun part. We put all the lights off and you only have your phones. Real scary shit. Any method is cool as long as you don't hurt anyone obviously... What do you think?" You think it's actually kind of interesting and smile: "It sounds fun... I mean... I am not that into games in general but I bet it will be fun for many."

She fans her face and gets up and looks at you: "So, it's a lot of stuff to do. There's tripping hazards here on the floors, and we gotta get the sensors and vibes. I'll go grab those from my van and you can start pulling these cables up. You seem to know how to do it better than me..." Her voice breaks and she almost smiles. You reach and she lets you grab her hand while she is frozen in place: "I-I think we'll have a lot of fun. It's because you thought it all up. Of course it's going to be great." She looks down and nods: "S-sure... got it. I will just go now... and you, stop being all cutesy with me or I'm going to split in half, dumbass." You giggle on your hand as she hurries off and starts to sort out the cables snaking around the stage.

They are mostly well placed and you do not have to lift anything heavy as you gather them. You eject many of the cables from one another and make nice neat bundles from them. You get everything done around the time when Iris gets up the stairs with the large cardboard box with the stuff. You help her and she opens the box giving you quite the view of her ass, she doesn't seem to mind too much and pulls out a machine with a wrist wrap. "Look, this thing monitors your pulse. I calibrated all of them before-hand. No need to test them now." You think it looks quite impressive and ask: "D-do you like this kind of stuff? I mean, with electronics and such?" She looks behind her shoulder at you and mutters: "Y-yeah... obviously..."

You smile and put it on. It has a power button but it has some sort of mechanism attached. It's really impressive and looks expensive. You push the power button and some dots appear on the screen and then a pulse, 79 bpm. You smile and tell her: "It works! It reads my pulse alright." She walks to you and checks. "Yeah, good. It's a little high. You didn't look at my ass just now, did you?" She looks dead into your eyes and you go all red. The meter rises up to 85 and you say shyly: "M-maybe..." Suddenly she takes your arm and wraps it around her and gets at a hugging distance. "Hug me... let's see what it reads from that." You do that and feel her bony and fragile body press on your soft one. She feels so tight and snug and it's hard to let her go. She looks at you and sighs: "Fucking hell... just a little hug would've been fine... we are just checking if it jumps..."

You know she doesn't mean it and just show her the meter. It's all the way up to 106 bpm. She gulps and takes a step back. "Yeah, seems to work... The threshold is 110. Then it activates the vibe. I think we should try that too. Let me just fetch it..." She goes to the box and you just stare at her nice hips and thin long legs as she bends down to grab it. She has a very skinny body, but if she had just a little more meat on her, she would literally be a model, that's how perfect her sizes are. She turns back and catches you looking but doesn't mind again. "Here, this is what you'll plug in your vag. I couldn't test it at home... I mean... shit..." She has a weird pink plastic object which looks kind of like a water drop with a thicker end and a long thing coming out - you assume it's the transmitter and the thick part goes inside.

"Do you mean... I-I..." You blush and look away as she shouts: "NO! Fuck! No, I don't need you to do that! Hey, just get your heartbeat up..." Then the vibrator starts to buzz and it scares the skeleton girl making her drop it: "AAH! SHIT! AAH!" She jumps and backs towards you. It vibrates on the floor almost jumping due to how hard it's going. It makes a rattling sound and looks absolutely insane, no vibrator is supposed to vibrate that much. You check your wrist and it's all the way up to 120. You look at Iris and she is fanning her face: "Yeah... looks like it's working alright... ok, calm down now, March?"

You wonder how it would feel inside and your heartbeat just races. It would feel so intense that you bet you would cum within one minute easily. She shakes you and you look at her face red and see that your meter is close to 130. "Shit... just... go in the tv-room and cool off. It's fine, as I told you, this is that kind of party. It's safe, I know it looks a little scary now... hey, March!" She screams as you are staring and snap out of it and apologize. She guides you to the tv room and after a good while you are calm enough that the meter is down to 80. You leave and see Iris putting the gadgets up on a table. She looks back and mutters: "Fuckin' finally. Come help me organize." You are deep into it now and you feel like it's about to be the end, but with Iris, it feels like it might just be the beginning.
