Capture the Goddess of the Forest nearby.

After you've had your fun with Mordina, you take Etherial and Raeta out into the nearby Woods.

The latter told you a tale about a minor Goddess named Dryanna that guards the Pine Trees.

You need to draw her out, so Etherial is up again.

You summon some treats that you know will draw out the Dryads and toss them into a clearing.

On cue, a dozen or so of the little things run out and flitter about.

So cute.
Time to get them.

You turn to the naked Raeta after sharing a look at Etherial.

"Would you be a dear and check her arm shackles for me?"
She nods.

The Goddess gets behind Etherial- who's already nervous- and bends down to check them.
While there, she's at eye level with the other Goddess tight ass.

You knew that she couldn't resist, so you smile as she spanks her playfully.

This freaks out Etherial, who projects another wave of her power.

In a flash, all of the Dryads lose their earthen 'clothes' and freak out.
This gets the attention of a nearby Satyr, who was, of course, lying in wait.

Suddenly, one of the larger trees transforms into a large Elven-looking Goddess wearing pine bark as clothes.
Naturally, this spooks off the horny goat man.
