Go for the ass.

Remembering the heavenly feeling of slipping into Rea's well lubricated ass, you decided to employ the same strategy here. Getting a good hold on the slippery water type, you brought your cock to Arya's dark blue pucker and pressed in, sliding near effortlessly into her warm rear end.

The effect was immediate. Arya roared in anger, and attempted to reach back and grab you. "Get out of my ass human boy!" She yelled as you ignored her, driving deeper into her ass. Arya suprised you then. Just as you bottomed out, she leapt back, slamming you into the ground with her atop you. You might still have been in her ass, but she was definetly in control. And pissed.
