It is! Unfortunately Phee does not have any food on herself that she'd enjoy eating, so they'll just be stuck stewing in awkwardness together.

After a few moments, Eva gets up the courage to ask. 

"Do you want some M&Ms? Or just some gorp? It's cool if you're not interested, it just feels awkward not to ask."

"Sure to the M&Ms, thanks! A-and sorry about the awkwardness?"

"It's cool!" 

Eva picks through her gorp a bit to get a handful of M&Ms together, then hands them over to Phee. "Here you go." 

Then she eats the double handful of peanuts and raisins she picked them out of. 

"Thanks!" And Phee will snack on them.

Her honor satisfied, Eva goes on and eats the rest of her lunch.

"Mind if I have a little more water?" she asks after her meal is done. 

"S-sure that's fine!"

You should ask her if she'd like some cum with her water.

No.

Eva gets out her bottles again. "This time I'll refill all my bottles so we don't have to keep going back to the spring."

She sits down on the sand and waits for Phee to summon her water again.

"That's reasonable!" And then she'll get to work summoning more water.

And Eva fills her pair of hard plastic bottles, as well as several glass ones. She doesn't bother to separate herself from the glass, this time. 

"There we go." 

And she takes a deep drink from one of the glass bottles, knocking back more of Phee's water. When she lowers the bottle again, there's a playful smile on her face.

Phee manages to avoid moaning from the feeling of (her water) being scooped up into bottles, even when Eva starts using the glass ones.

And then she fails immediately once Eva starts drinking her (water), letting out a flustered moan, followed by shyly pouting when she sees the look on Eva' face.

Eva smiles and runs a hand through her hair, and pulls out a brightly colored fruit with a shiny pink peel and a juicy firmness from her backpack. "So, fair's fair, you have an embarrassing power, I have one too. I'm going to eat some of this, um - I call it pussyfruit, to be perfectly honest - and then I'll get to sculpting, and you can listen to me have a fun time in your turn." 

She should instead eat our pussy-

We don't even have one of those.

Yet!

Ignoring her intrusive thoughts, and lingering disappointment at not being drunk more. Phee shrugs shyly and says. "Y-yeah that's fair and" resisting the urge to ask about why she calls it 'pussyfruit' as she'll most likely regret hearing the answer "can I watch you too while you sculpt, or just listen?"

"Yeah, you can definitely watch. I mean, you've already seen me in a much more compromising position, and I am drinking you. We're going to get here eventually, might as well shortcut it a bit." 

Eva goes and gets her cushion from in the tent and sets it down on the sand, then sits on it and takes big bites out of the pussyfruit. 

Gradually, her expression changes, a flush coming to her cheeks. Each swallowed bite seems to put more tension into her body, and by the end of the fruit she's making little happy mmmms after each bite. 

She giggles at the end, the laugh surprisingly high-pitched even for her feminized body, and makes little gripping motions with her fingers in the air in front of her. "Mmm, tingly. Tastes delicious, too." 

Then she gets a rakish grin, and buries her hands in the sand before her. The sand of the desert reacts to her hands, coming up in long tendrils that quickly solidify into glass, and she wraps coil after coil of glass into the rough shape of a vase, laying down layer after layer. 

After she settles the basic shape, she starts kneading the glass with her hands, it moving partly with the motions of her fingers, partly with her will. Her blush intensifies as her hands stroke the glass, massaging and kneading, and before long she's sighing and breathing fast. 

Her motions stay smooth, though, the clear product of practice, and steadily she shapes the glass closer towards its final form. 

"Yeah, you can definitely watch. I mean, you've already seen me in a much more compromising position, and I am drinking you. We're going to get here eventually, might as well shortcut it a bit." 

Phee nods. "That makes sense, thanks!" and then she'll sit down nearby to watch.

Gradually, her expression changes, a flush coming to her cheeks. Each swallowed bite seems to put more tension into her body, and by the end of the fruit she's making little happy mmmms after each bite.

D'aww, cute.
