I think Jon really, really enjoys watching other people have sex. Has no desire to personally involve himself in the process, really, would much prefer nobody else even knew he was watching at all. Watching porn is nice enough, but it’s not quite the same. A not uncommon sexual fantasy for him is walking in on other people having sex, and they’re all too distracted to notice his presence so he hides himself in a corner and just watches them. Sometimes it combines with the rape kink and they catch him in the act and punish him for watching them, but sometimes they finish and leave without noticing him rutting against his hand in the corner.
We can also combine this with the tape recorders of course <3
Look I know they’re an extension of the web technically but why not play in a universe where they (subconciously or otherwise) respond to Jon’s whims? Popping up sometimes when other institute employees are masturbating or having sex and then finding their way to him. Jon listening to them while he fingers himself (he tried to resist. He really, really did. But none of his usual fantasies were working and he was so close and surely it wouldn’t hurt? If they didn’t know? If he allowed himself this private little pleasure? And of course he feels guilty but it just feels too good to stop…
