In the Ginrei Special, a spinoff of Giant Robo, episode #1 has a lengthy scene of Ginrei tied with her arms behind her, more rope above and below her ample bosom, and suspended. Episode #3 has a brief scene of Ginrei webbed to a wall.
(For the benefit of all you young 'uns, Ginrei is one of anime's all-time great babes.)
