So I’ve kind of always loved portal bondage but it’s kind of a very niche, I don’t see it a lot. So imagine cuffs with a fabric or latex that filled in the ring, and as someone slips it on there arms and legs go into some kind of pocket dimension. Basically this turns them into a full on human fleshlight that can be easily transported and needs little to no restraints. Maybe people are often put in this kind of thing to make them perfect for cum storage, or egg storage, or just the perfect breeder that doesn’t take up as much space. Idk there’s a lot of options I just love this concept. 💕
A lot of options, indeed <3
Since the cuffs are so easy to put on and take off of anyone, that means anybody could so easily become just a toy for use with no access to their limbs. No arms, no legs, just a torso and head - the important parts for use. A proper toy only needs to have holes available. Anything else is a bonus at best, but a threat at worst. It's generally not worth allowing a toy to have access to limbs while they're being used.
My guess is that portal bondage would be popular at parties! Maybe someone loses a bet or a game, and they have to stay in the cuffs for the rest of the night while everyone uses them. They have no say in what their holes are used for, say nothing of which holes are used in the first place, so they end up taking a cock in each hole at all times, cum pumping into their cunt, their mouth, their ass. By the end of the night, they're a sloppy mess, covered in the seed that couldn't fit inside after they'd been stuffed to the brim, their belly swollen and swaying. They're probably too much of a fucked-out mess to comprehend the other partygoers planning to keep them in those cuffs for a week. Probably longer, if we're realistic - it's just too good of an opportunity to pass up. There's no way for them to escape, anyway, and it's hard for them to protest if there's a cock down their throat.
Another scenario I like the thought of is some poor soul ending up as the subject of some experiment or another. Maybe they got caught up in some bad business and have to do some community service, so they end up volunteering for a..."medical" trial at the hands of a bio-research organization. When the cuffs are slipped on and the scientists leave the research room, however, the subject realizes that they've been restrained not only for ease of access, but also so that they can't fight back against the monster that enters. They can't escape the long, thick ovipositor that slides into their cunt, pressing up against their cervix to deliver a payload of rubbery eggs into their womb that swells their middle uncomfortably. It only gets worse when the monster fills their guts, but at least it's over, right? No such luck - the monster needs to use their mouth, too. Their stomach is put under the same treatment, and they're left hanging from their bonds with an impossibly full body.
Maybe someone gets taken off of the streets by someone with access to portal bondage and an obsession with passing on his bloodline. He snaps up the unsuspecting victim and makes sure they can't escape, their limbs disappearing into an unknown pocket dimension and out of their use, and promptly breeds them in the back of his vehicle before taking them home and hanging them up in a private room. They're just so easy to store that he doesn't even have to worry about setting up his basement - he can just hang them from the ceiling wherever he wants with chains attached to the cuffs. Of course, that also means he can fill them with his seed whenever he wants, making sure that they're bearing his children. It might be a little uncomfortable for them when they start showing, to have the weight of a baby pulling them down, but it's not like they can do anything about it.
