Grab her, with some help from the weeds

Even under the water you can hear Kates throaty attempts to start screaming again while you grab onto her leg and pull her backwards in the water. She just barely manage to keep her head above the surface, and shuts up for a moment as she gets another mouth full of water.

Meanwhile you get a hold of some of those slimy weeds,wrapping it quickly around her ankle and manage to tie it in place. Then you repeat the process with the other leg as well, while she's still kicking and struggling to get away, until she's **** to hold herself up with only her arms to keep herself floating.

You watch her struggle for a moment, smiling as she manage to reach for the boat again and feebly try to pull herself up inside of it. She doesn't make it of course, with the weeds being much too strong for her, and that's when you return to the stage again.

Approaching from directly underneath her, you have no trouble at all reaching up between her legs and sliding your fingers across her crotch. Her struggles grow wilder again in an instant, but mostly she's just wearing herself down in vain while you quickly cut her panties off of her and thrust your fingers to her exposed slit. The water doesnt help with the penetration, as it's the wrong kind of wetness, but once inside you find her a lot easier to work with...

Soon you're fingering her furiously, while she can barely even try to fight or scream any more but just hold onto the gunwale of her boat to keep herself breathing...
