Time to get boned

Everything is ready and in order. You are waiting with Iris for everyone to arrive. You see Helena there too a lot calmer than she was earlier. And Chelsie and Nat both there. The demon girl joins you and you step away and let them explain the game to everyone: "Alright people! I hope everyone is still sober enough for one more game! It's the special game for this year! All put together by Iris and me." Chels tries to give Iris a little supportive hug but she brushes her off and rolls her eyes. "Eh... yeah. This is where the scariness comes, people! It's time to scare each other good! Really good! Would you explain to them, Iris?"

The skeleton girl takes a heartbeat monitor and a vibrator in hand and shows it to everyone. There's some interesting comments in the crowd and some are giggling and some are expressing discomfort. "So, basically this thing shows it when you are scared and this other thing is going to stimulate you internally. Basically you put it in your pussy and it will vibrate if you get too scared, basic enough?" People are talking loudly and you see some of them starting to panic, Helena included, you feel a little bad.

"Yes, this is that part of the party. Everyone participates. Going outside is illegal and doors that can be locked can't be locked, ok? Everyone will stay in the house and this will last for an hour. Chelsie, Natasha and I will not participate, got it?" People are still talking and you hear that most of them are confused or unsure. "What if one of us has to take a shit? Can't we lock the door? What the fuck?" Someone shouts and Chels shrugs: "Well, yeah... try to not actually shit yourself, alright? Don't be dicks to eachother, a'right?" She clears her throat and continues: "So, just take a pair and put them on, come on now." People start moving and Iris looks at you. She hands you the gadget in her hand and gulps and takes out her fan. Chels rounds everyone up and more or less reluctingly everyone gets their gadgets. You take note of two people in particular. The ghost girl and the mummy girl.

Both are having a hard time getting the gadgets on and with the mummy girl they end up having you result to cutting holes in her costume. With the ghost Prichilla the huge tribal girl picks her up and you swear... she just rams her arm under the costume making the poor girl scream and then snaps the wrist monitor on her. You also see the robot girl and the scientist girl talking about it: "I know it's stupid, but I believe we have no choice. I installed a latch on your crotch, let me just..." Kruya the scientist girl helps the robot girl and with that latch it actually works rather well it seems. There's also the horse girls. But they seem to not have any problem putting them on. The front girl takes the gadgets through the horse's mouth and you can just imagine what happens inside.

Personally you go to the bathroom and raise your balls and spit a little on the vibrator and push it in as far as it will go. It is a little uncomfortable, but when you get used to it it doesn't really restrict your movement too much. You also put the heart beat monitor on and it reads a pretty average 76. Back in the party room you see Iris doing something to the wrists. She has a key and she is locking every single one with it. You go to her and she puts the key in the keyhole attached to your monitor and suddenly the power button's light turns off and something snaps shut. "It has a lock, you can't take it off now and you can't turn it off either. I guess good luck, March. See you later..." She says and hurries off with the Darlingtons.

You turn around and see everyone for the last time and then suddenly all lights go out everywhere. It becomes pitch black and people scream and take out their phones. "AH! Shit! Mine is dead! Anyone got a charger?" It's the clown girl and you feel actually really bad for her. Nobody seems to have one and she goes through everyone but is left without anything. You decide to go downstairs and just see how it goes while sitting on the couch and relaxing. You pass by some other girls and notice that many of them are sticking together, unlike you. You sit down and wait. You even turn off your flashlight to save battery and just sit in the darkness and calm your breathing. Then you hear it. In the second floor somebody screams and after a second you feel even louder screaming, only out of pleasure. You listen to it and try to not think about it for a minute and then she goes quiet. You suddenly start to wonder how. How does it end?

Then you see someone run downstairs and pass you and go in the kitchen and open the fridge and when there's no light she curls up into a ball and you hear weaping. You are pretty sure she must be close to the limit and hurry to her. "Relax! I'm not here to scare you!" You say and notice the red hair and glasses, it's Helena! She is staring at her wrist and holding her mouth. You look and see that it's at 105. You sit next to her and take her hand. "Helena, it's me! Look, it's alright." She has a terrified look on her face and the heartbeat stays high. "I-I-I-I saw w-w-what happened to the... to the other girl I... Ngh... I-I-I..." She stammers and the heartbeat raises up to 109. You hug her and hold her tightly: "Please, calm down, please..." You hold her and she tries to breath and after a moment you feel her tension fade. You wait until she is alright and look at her wrist and it's at a better 80.

"M-March... t-thank you... Thank you so much! Your boobs were all on my case though..." She says and gulps. You smile and help her up. "Have I ever told you that you have very nice full lips?" She goes red and shows your the monitor it's up at 84. "S-stop... not now..." You agree and stay with her for a while. In that time multiple other girls get triggered and end up going quiet in the dark. Then there's one just in the other room and you have to go see. You only see the girl twisting and turning in the light of her phone. It is the redhaired tomboyish girl who came in just after the glowshow. She is screaming and humping the air and it looks absolutely horrible. She pulls down her pants but not before she cums and it's pretty clear that she's a futanari as she sprays a lot of cum on the floor and passes out right over it. The vibrator turns off and you approach her and see that she's hardly awake and drooling on the floor. It looks so bad, you are worried if she got hurt. "W-why don't we just... like, take these vibrators off? T-there's no lock or anything..." Helena asks.

You were thinking the same thing but knowing Iris and Chelsie there's probably some way they would know. You don't want to risk it and tell Helena not to either.
