June idea suggestions!

Princess Peach and Princess Daisy in latex, kinky versions of their princess dresses; Daisy, with a yellow and orange rubber dress, is in a leather harness and has a collar with a small Bowser sigil tag on it, wearing a black ballgag with Bowser's sigil in red; she's wearing ballet boots and has her ankles cuffed and chained, but her arms are free. Peach is bound more heavily, with a heavy armbinder and a pink and white hobble dress version of her princess outfit. She has a pink latex hood over her head with a ring-gag implement. Daisy is holding Peach's leash and the remote to her toys, making her hobble hopelessly behind her.

Astorius Blake

D.Va tied bent over a bench, with her arms in a reverse prayer, as Widowmaker bangs her from behind with a big strap-on.

Lygot

Chris Yukine and Maria Cadenzavna Eve from Senki Zesshou Symphogear series sitting on sybian, tied in straitjackets with exposed breasts and wearing ball gags. There is milking machine attached to their breasts and sybian have squirting counter increaseing vibrations on girl with lower score. You can give them costumes and tights in the colors of their superheroine costumes.

Swamplon

Konosuba: Darkness and Aqua bound in connected predicatemnt. Darkness is squatting in strappado(with armbinder usage) over slightly inserted in anus big dildo. Aqua is hogtied vertically (only knees are on the ground) with dildo inserted into her ass the well. If darkness hands go down (Which will happen if darkness go down on the dildo ) then dildo goes deeper into aqua. Darkness nipples are also connected to aqua toes so if Darkness goes down Aqua needs to stretch her foot. So if Darkness doesnt go down on Dildo they can pass time somewhat coumfortably. Unfortunately for Aqua Darkness is Darkness... (Darkness is pretty happy in the situation and Aqua is pained/Mad)

Fudoff

Arcade Kai'Sa and Arcade Caitlyn, stripped naked, wear only gloves and their thigh highs, have to compete in an arcade bondage game. But they are stuck to each other by anal beads, so they can't shake each other off, but still try to hinder the other, because the loser gets a harsh punishment. The goal is to reach a vibrating dildo and who sits first on it completely wins. Kai'sa's and Caitlyn's arms are tied together and a nice gag makes the scene even better. Also thanks to Rereyre for helping me refining this idea.

Cheeryo

The Doll and Lady Maria of the Astral Clocktower from Bloodborne bound up together. Bloodborne Victorian gothic aesthetic and psudo-steampunk technology creates some interested looking opportunities for bondage with gears and chains... For this, I suggest they be hanging up suspended, where whenever one struggles it ratchets the other one step tighter. Bloodborne has plenty of eldrich monsters with tentacles, and also more normal monsters like werewolves, so if you wanted them to be getting fucked there are plenty of unique thing to do it with
