In this narrative, set in the Fullmetal Alchemist Brotherhood universe, we follow Ren Jinhai, a Xingian prince and prodigy in the art of Alkahestry. The story begins with Ren’s life, whose interest in human transmutation is triggered by the death of his mother when he was eight. Although Ren eventually realizes the impossibility of resurrecting the deceased, he develops a unique ability to enter the Truth portal through meditation, allowing him to perform remote transmutations without a matrix. Ren’s character is defined by his compassion, empathy, intelligence, and unconventional worldview.

Due to the pressures from the succession conflict in Xing, Ren travels to Amestris to expand his knowledge. Upon arriving in Rush Valley, he coincidentally stumbles upon Winry Rockbell’s shop and seeks her assistance. Winry becomes intrigued by Ren’s passion for learning, and their shared love for automail and alkahestry strengthens their bond. They spend the day exploring the bustling town together. While working on a project with Winry, Ren opens up about his past and Winry can’t help but compare how alike yet different he is from Edward. As they collaborate, they find themselves drawn to one another and eventually share a passionate kiss.

Following their impassioned moment, Ren transmutes a spare wire into a beautiful necklace for Winry as their hands begin to explore one another’s bodies. They share more kisses and Ren’s hands roam over Winry’s shoulders, ass, belly, and finally her breasts under her crop top. Winry takes charge and pushes Ren against the wall, groping his member through his pants.

Despite Ren’s desire to pause and make sure they both feel comfortable, Winry continues, wanting to pleasure him. Eventually, Ren verbally asks Winry if she is sure she wants to continue, and they both confess it is their first time. Ren uses his alkahestry to transmute the inhospitable workshop scent into the calming aroma of roses and lavender to create a more intimate atmosphere.

Winry proceeds to explore Ren’s manhood by taking him into her mouth tentatively, learning quickly despite their inexperience with one another. The taste and feel of Ren in her mouth provide an unexpected confidence and determination to please him. Ren, straining to maintain control, helps guide Winry’s head and feeling her breasts under her clothes. Sensing the impending climax, Winry massages Ren’s balls just before he climaxes in her mouth.

As Ren reaches the peak of pleasure, Winry decides in a moment of trust and devotion to swallow his essence, strengthening their bond.

As Ren’s arousal begins to subside, he enters a state of refractory, his manhood gradually shrinking and becoming more sensitive to touch. While in this hypersensitive state, he finds a newfound pleasure in sensations he had never experienced before.

Winry, captivated by the intimacy and the uniqueness of the moment, continues to tenderly play with Ren’s manhood – her fingertips gliding over the oversensitive shaft with delicate curiosity, intimately experiencing his physical transformation.

Although the sensations are somewhat overwhelming, he finds comfort in her gentle hands as they continue to affirm their love and devotion to each other through touch.

Winry’s other hand, encouraged by their shared experience, continues to play with his balls, her careful motions imbued with a mixture of passion and respect for their shared vulnerability. This tender and intimate dance is an awakening for both, as they continue to learn and explore each other’s bodies and boundaries.
