Titled "Phina - Private moment"
From the artist:

Oh dear, here I go showing off poor Phina again, caught in an most embarrasing moment .. this is about as adult as I'll get for a bit.

Note the green glow about her wings as she channels a small bit of life energy. Although often used to heal others, its energy can also be focused to enhance pleasure.

On rare occasions while perfectly alone, she's been known to indulge in her own powers and can actually induce a full orgasm at any pace she desires, suppressing or enhancing it in herself and others if needed. Such physical releases help her to achieve the meditative state needed to regain her energy.

Although she is considered by some to be a somewhat of forest diety due to her unique abilities and preference for the quiet of open forest glades. She's actually quite physically normal, with the similar issues as any other female and is most certainly capable of bearing children. Though, her emotional empathy does cause her to often only seek close relationships with those with pure hearts and intensions.
