This story was written for the following prompt: "A harness that holds pocket dimensions which you put your arms and legs into, effectively allowing you to be without limbs and therefore helpless."
Contains: temporary limblessness, bondage.
"This is... weird." She wiggled her arms, feeling like they were completely normal, but the only thing visible was her shoulders flexing slightly. It looked as if she didn't have arms, her limbs just ending at the shoulder with a strange taut fabric stretched over them. The only difference in sensation was a slight tingling as she waved her hands around, feeling air swish past them.
"Isn't it great, J?" her friend enthused, picking up the lower half of the harness from her bed. "Want to try the legs?"
Janet laughed. "God, you buy the weirdest stuff. And no, I don't really want to become a torso."
"Are you sure? It's really fun. There's no way to get it off yourself, and you just feel so helpless..." Her eyes glazed over a little, a yearning expression on her face.
"Hellooo... Earth to Emma..."
Emma snapped back to reality, flushing a bright red as she tried to play it off. "I mean, I'd imagine so. If you liked that."
"Emmaaa..." Janet asked, drawing out her name. "Is this a bondage thing?"
"Yes. I mean no! I mean-" Emma buried her face in her hands, her loose brown hair falling forward and obscuring her further. "...maybe."
Janet giggled. "You can just tell me. I'm not going to be weird about you liking what you like."
"Well, okay, yeah," Emma admitted. "I just wanted to see if you liked it too."
Janet shrugged, a strange maneuver without visible arms. "It's okay, but being tied up - well, dimensionally restricted - doesn't do that much for me." She looked down at the harness as a thought struck her. "How do you even use this thing by yourself? I can't imagine how you'd put it on."
Emma sighed, her expression turning glum. "I wish you'd asked me that before I bought it. I tried it on in the store with the attendant, and it was just... " Her eyes got a little wistful again, but she came to her senses in only a moment. "I didn't think about the fact that I needed a partner until, well, I got home and tried to put it on. Then I felt really stupid."
"Couldn't you return it?"
"I could, but I really do love it. I guess I just have to wait until I get a boyfriend who likes this kind of thing." She sighed, and Janet sat down next to her on the bed, trying to put an arm around her shoulders before she realized what she was doing and simply cuddled up against her friend. After a few peaceful moments, she sat bolt upright.
"Hey, why can't I just do it?"
"W-What?"
"All you need is someone to put you in and take you out, right? I can do that much."
A grin spread across Emma's face, and she turned and hugged Janet. "Oh, that would be amazing! Thank you!"
"What are friends for?" Janet said, smiling. "Why didn't you just ask me before?"
"Well..." Emma blushed, pulling away. "I didn't want- it's a little personal-"
"Yeah, yeah, you're shy. What else is new?" Janet leaned forward, bumping shoulders with her. "Now come on, get me out of this thing so you can get in it."
"R-Right now?"
