You the wish that it was a nude beach, so as to let him truly have him in her. You then take her breasts and start to squeeze before wishing for the ability to make humans partly to fully animals.
With the new power you make her part fox for sex, if not just to make her cuter, and Ava let you fuck her like the girl in the heat she was. You decide to find out what she wants, only to find her wanting you as her dominent, her master, and owner, in all her forms. So he excepts the self givin challenge of having sex under water 5 ft min for the climax of sex.
After going back on land he let's her dress back up before they leave. She was wearing a jacket(no shirt no bra) and a pair of extra tight sweat pants (crochless panties) and a silver and gold fox tail stiled charm with a tracker on it. She was his to fuck since that is how she wished it to be.
