Seiran cries out in surprise as the dark flames wash over her and the demoness, knocking her back on her bare butt. Soon, her crotch burns with a strange heat that flows deep inside, causing the avariel to grunt and groan in anguish and a strange sort of fevered desire. She feels her clit swell, split in two, then the upper one starts to swell and extend unnaturally. Something heavy swells and grows next to it, feeling unnatural and strong. Soon, she gives a loud cry of ecstasy and pain, and she feels something explode from her crotch. As she regains her senses, panting, laying naked in the dirt, she becomes aware of an erect penis sprouted from her crotch, throbbing slightly as it stands just about her throbbing clit, her pussy obscured by two decent-sized testicles.
Seiran, in surprised, reaches out and grabs it to make sure it's real. The sensation causes her to gasp sharply at the alien but wonderful feelings, and she realizes it's not only a real dick, but her own. Anna's magic must have altered her somehow.
Standing up, she lightly strokes the new penis, she looks longingly at Anna rutting the demoness, and feels a strange longing within her. Ever since she became a priestess, she realized she had little time for children, but still longed for the idea at some level. Upon finding Icaria once more, she wanted to have a family of avariel, not just to replenish the race, but to make a loving family with her former friend and lover. But... but the sensation of the new penis, the realization she could now actually make children of her own in Icaria's womb... the sensation of being pregnant and horny... it awakens a strange desire in Seiran. Not only does she realize she can use the penis to purify as she can with her pussy, but part of her wants to knock up her friends too. Make avariel babies with Icaria, maybe even winged kittens and fox cubs with Madeline and Anna respectively.
As she looks at the demoness fucking Anna, she catches a glimpse of her slit, hiding behind her balls. Feeling her blood hot with desire, she reaches out, grabs the demon's hips, and thrusts her new penis into that hot, needy pussy, gasping in surprise as she feels the sensation of a pussy around her new dick. She shudders as a bit of precum leaks into the demoness, but starts thrusting her hips as she saw many males do, fucking the enraptured demoness as she begins to feel her holy power flow through her new dick, a strange but wonderful sensation.
