A tub of fun

Once Donna’s done peeing, you switch on the sprayer and the cold water hits her back. She yelps in surprise and tries to wriggle out of the way, but only manages to roll over onto her side. Amazon toughness or no, she squirms to try and keep her head out of the ice-cold spray, but there's not really anywhere for her to go as you run the sprayer up and down her body. You hose down Donna's chest and face and the floor of the tub until all the yellow is gone and Donna's nipples are sharp enough to cut glass.

Grabbing her shoulder, you roll her onto her stomach face down in the tub, wet hair splayed everywhere. Distracted as she is, it takes her a minute to realize you've closed the stopper and the tub is filling up with water. There's no fear in her face - what you can see of it through all the hair – but she’s clearly not enjoying the cold. She tries to talk a few times but whenever she opens her mouth. you hit it with the spray, so she never manages anything like a sentence.

Soon she's having to crane her neck back to keep her head out of the water, still trying to look unconcerned. You reach out and run your finger along the sole of one bound foot, eliciting a shriek. Her head jerks forward into the water and comes up sputtering. Just as you thought: our girl is ticklish!

You go to work on her feet, the backs of her knees, her armpits, and the back of her neck. She laughs and squeals and cries, all of which make it extremely hard to hold her breath or keep her head above water. Soon she's coughing and spitting up water. She's too proud to beg, tho honestly you doubt she could get the words out if she tried.

You grab a handful of black hair, haul her head up out of the water and whisper in her ear, "How do you think Diana will react to finding her baby sister's body drowned in her own tub? That should be just the nudge she needs to get her where I want her."

Under any other circumstances you're sure Donna Troy would face-her death bravely. But the cold, the helplessness, the added concern for her sister, and the notion that her only value to you is as a pawn to torment Diana all combine to crack her Stoic Amazon facade. Her eyes go wide with if not fear then definitely something adjacent. Her mouth opens with whatever answer the lasso compels her to give to your rhetorical question. Before she can answer, you let go and her head falls back under water.

You don't need to hold it under; gravity and bondage take care of that for you. She sputters and thrashes, having not gotten a good breath before she went under. She flails around for awhile trying to hold onto the little air she has in her lungs.

Then someone sticks a finger in her asshole and she gasps in surprise, which is an unfortunate thing to do underwater. She coughs out water and air, thrashing around like... well, like a drowning woman. If it wasn't for the lasso she would undoubtedly send both you and chunks of the tub flying, but as it is her struggles are in vain, gradually getting weaker...
