Sofia answers yes

"I will need to do this," Sofia states simply, her blush brighter than ever.

You stare at her and ask "Are you sure?"

"Well, until our father is dead, he will not be satisfied unless you have the appearances of being a male and that means no pregnancy for you." Sofia seems to be gaining strength and conviction pushing aside her blush with these words to you. Turning to Whisper, she says, "Okay, I'm ready."

"This should be interesting and fun." Saying that you see a cock emerge from the slit between Wisper's legs.

"To save time with my father, I will take your seeds," Sofia says removing her clothing. As she says this, the dryad lays her on the floor, gently lowering her from standing to lying on her back using roots that shoot up for support then disappear into the earth leaving it soft and smooth under Sofia followed by moss growing out of nowhere to cushion her back. Sofia opens her legs revelling her moist pussy. Your own cock starts to harden as you watch them prepare.

the dryad lowers down shoving her cock inside Sofia's pussy. You had torn her hymen the previous night so there was no blood but since her cock was shoved straight into Sofia's pussy raw, she appeared to feel a little pain. "owweee" Sofia squeal.

"Oh, Yes" moans the dryad. She starts to move back and forth in her pussy. Both hands reach down to Sofia's breasts. The sweet smell, her pheromones increase indicating the dryad's arousal.

Watching this display, you can't help but feel arousal and as your hand moves to your own cock, you find that vines are already removing your pants for you and a most peculiar flower seems to grow in front of you.

"I made that flower for you and others like yourself," the dryad tells you, "It can stimulate you in your pussy at the same time as you fuck it with your cock. It will also preserve your seed so that any dryad can use it later for impregnating themselves or any other female."

"UUHMMMMMMMMMMHUUUUMM" you realize that the dryad has found Sofia's 'sweet spot' as you hear her moaning. Spurred on by the moan, you plunge your cock into the opening of the flower and find that your own pussy is getting impaled as well.

You remember how good it felt to plunge your dick into the dryad and your sister but this was the first time you have ever been on the receiving end. At first, it felt as though the plant's cock was slowly entering and lubricating itself and then it hit a wall it seemed, until it pounded straight through and kept a rhythm equivalent to your own pounding into the flower.

"Oh, Oh, Oh" You cry as you feel as little vines move up your body to take their place on your erect nipples under your shirt.

All of this sends you over the edge, "OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO" you cry. You feel your pussy reach orgasm and you also hear Sofia cry, "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHH," After a moment, you notice that your cock has also ejaculated with your orgasm but the plant's cock only seems to slow down to match your pace until you both finally pull out of the pussies.

The three of you take some time to recover and you and Sofia redress to get ready for the next part of your journey.

"Thank you, the seeds I implanted in you will germinate inside you and the seedlings you grow will spread far and wide providing protection to more forests of this land." She turns to you, "Perhaps they might have your wife's beautiful blue scales to protect them from the dangers of the world, my dear Sofia. Whatever happens, our children in your belly will be attuned to nature. Now regarding the seed that you have me." She says patting the plant you were fucking before. "I will preserve the seed until such a time should come that have need for more children. This will allow you and your offspring to forever pass through my forest so long as you bring me and mine no harm."

"We no longer have any obligation to meet but if you'd like to visit at some point in the future, I will always welcome you." Whisper says this last bit as a parting as she waves us toward the direction of our father's castle and reveals a clearing where our horse is waiting for us while eating the grass without being tied down to anything. Nearby, there is a stack of firewood and other supplies we will need. "You will find that the castle you seek is just beyond the path I have laid out for you both. I would still suggest spending the night here before you go. "
