i love thinking about both viktor and jayce so fat it hinders them at having sex so they have to get creative :3c
jayce's fatpad being so big it swallows his dick completely (and further beyond, obviously); and viktor's ass, hips and thighs being so packed with fat it makes it difficult to even reach anything as well <3
when both were still smaller; and jayce's cock not completely lost in a sea of fat; they get a kick out of the way jayce's fatpad has to be squished aside in an attempt to even get close to fucking his partner. or viktor wanting to try and fuck jayce's fatpad; both discovering that it feels fucking amazing so they try it more often as jayce's mobility dwindles
or viktor face first in jayce's massive fupa trying to suck him off, getting absolutely smothered in it but he's exactly where he wants to be🖤
viktor would get a kick out of teasing jayce that he can't fuck him anymore (can be applied to both bc i like them switching). viktor having to use a strap on jayce to get the illusing of getting fucked by his immobile partner, while also loving the feeling of using jayce's navel for his own pleasure >:3
buut if we imagine jayce's fupa being huge and looking more like this, viktor can still have his fun fucking jayce's fupa no matter how big jayce gets, his fupa will always be massive ;3
and maybe jayce is at a stage where even moving his arms is impossible, so viktor has to take over most actions, but they both indulge in it A LOT
jayce might not even be able to move his fingers much, but it doesn't stop viktor from trying to fuck himself on one of the thick digits. back then three of jayce's fingers filled him out nicely; now, at this size, even one finger is larger around in circumference✨️
or switched around with viktor being the immobile one first; jayce doesn't even attempt at trying to reach viktor's hole, his backside is far too massive that other ways would prove more successful :3
viktor would be immobile way faster than jayce, obviously due to the extend of his disability but also with the way his lower half gains much more quickly than his upper half. the amount of fat gathered on every part of his legs makes walking take way too much effort, not even to mention how difficult it is to even bend them with all the fat in the way. but oh, once he took his last steps and accepted immobility, his gaining accelerated; especially with the help of jayce
i'd also imagine viktor's navel being very sensitive so even just shoving a vibrator in that deep cavern can get him to his peak in no time, and ohh. jayce would absolutely use this knowledge to his advantage, teasing and maybe edging his poor, immobile partner. maybe jayce also decides to fuck viktor's pretty mouth.
his face is covered in fat, puffy cheeks squishing his mouth into a pout; perfectly for him to fuck his partner's pretty face while holding onto the fat surrounding it🖤
or with more of a size difference: still rather thin but slightly chubby vik getting pounded by jayce who's at least four times his own weight. jayce's huge belly is laying ontop of him, his fat hands holding onto any part of viktor he is able to reach, as he's trying his best not to get winded too fast. he's always careful not to hurt vik ofc, always looking out so he is laying comfortably and adjusting where needed. same thing with viktor looking out for his massive partner :3c
sometimes they try with viktor on his stomach, maybe laying over the edge of the bed with his legs cushioned so he's comfortable; this way, jayce probably has more space to actually reach his partner
