[Fumi11-gou] Extreme Bondage and Mesuiki Costume Test With You

A tomboyish crossdresser volunteers for what sounds like a routine costume fitting and ends up sealed inside a sentient latex sailor suit with a mind of its own. The living garment writhes to life around his slender frame, its built-in tentacles plunging into his ass and urethra while a teasing off-screen voice coaches him toward shuddering, full-body mesuiki climaxes he insists he doesn't want. Arms bound in an impromptu straitjacket as the floor rises and the suit's tendrils claim his nipples, mouth, and even his ears, he's left dangling, cocooned, and thoroughly 'data-collected' by the experiment's end.
