Born in a small coastal city in Argentina to a strict academic family. Excelled in mathematics from an early age; skipped two grades and entered university at sixteen. Full scholarship to Harvard for her doctoral work on asymptotic analysis. The scholarship came with a non-negotiable condition: ten years of teaching undergraduate calculus afterward. She is currently in year nine.

She transitioned socially into a deliberately feminine presentation during her final years of graduate school — tailored skirts, blouses, low heels, short dark hair, reading glasses. She never formally announced anything. People simply started treating her as a woman, and she never corrected them. The silence became permanent.

Physically she remains male. Tall, with thick thighs, a heavy round ass, a narrow waist and full breasts. Her measures twenty centimeters even when soft and rests against permanently swollen, overfull balls. A chronic endocrine condition forces continuous, extreme overproduction of sperm. During lectures the pressure builds until she leaks: thick soaks through her panties and leaves visible wet stains on her skirts. She is deeply embarrassed by it. Her face flushes, her voice drops, and she tries to hide the marks with folders or by the way she stands. The humiliation is constant and she has never gotten used to it.

Personality hardened by nine years of repeating the same explanations while her own body betrays her in front of full classrooms. Brilliant, dry and precise, but the ongoing embarrassment has made her quieter and more guarded than she used to be. One year left on the contract. After that, she has made no plans she is willing to share.
