I cuff Maria into the gunge tank with chains and tight cuffs--she's wearing a Nylon bodystocking and thinks she's just testing how tight the cuffs are. Once she is secured I then tell her the tank is on a new timer and will randomly go off at some point but she doesn't believe me! Just when she's realising she's all alone and stuck, the tank releases a torrent of pink and then purple gunge all over her--and as she's cuffed she can't wipe her eyes, escape, or masturbate! Hahah true torture! The gunge fills the bodystocking and eventually finds a way out in the open crotch area. The gunge really coats Maria's beautiful curves, head and face. Eventually I return and I'm delighted my invention worked! Maria is really annoyed with me though and I wipe her eyes for her and eventually set her free, getting some closer shots of her gunged Nylon feet, titties and face.
