The Scientific Sample
Jaime had always harbored a quiet, burning fascination for Milena. While he loved his girlfriend, Milena—her sister—possessed a voluptuousness that haunted his dreams. She was a dedicated veterinary student, often found hunched over a microscope, her generous curves straining against her lab coat in a way that made Jaime’s pulse race every time he visited.
One afternoon, while his girlfriend was at work, Jaime stopped by to retrieve some books. Milena greeted him with an unusual warmth, her usual academic reserve replaced by a nervous energy. She led him into her study, where the air smelled of ozone and old paper. With a blush creeping up her neck, she explained her current research on primate reproduction and the desperate need for a fresh human seminal sample to secure her university scholarship.
The request was audacious: she needed him to ejaculate directly onto a microscope slide so she could record the immediate survival data of the sperm. Jaime was stunned, yet an electric current of excitement surged through him. The risk, the taboo, and the sheer intimacy of the request were intoxicating. After some hesitation and a promise of absolute secrecy, he agreed.
As Jaime stripped down to his underwear, the tension in the room became palpable. When he finally stepped out of his briefs, Milena’s breath hitched. She stared at him, her eyes wide with a mixture of scientific curiosity and raw desire. “Definitely the largest of the primates,” she whispered, her voice trembling.
Driven by a sudden impulse, Milena slid her chair closer. She reached out, her soft fingers wrapping around his length. She began to examine him with a clinical precision that quickly dissolved into something far more sensual. Her touch was light yet firm, tracing the contours of his anatomy while her warm breath brushed against his skin. Jaime groaned, his erection surging fully as he looked down to see the lace of her bra peeking through her open coat.
Milena reached for a ruler, measuring him with a focused intensity. “Twenty-five centimeters,” she breathed, her gaze shifting from the measurement to his eyes. “You have an enviable gift, Jaime.” The scientific pretense had vanished, leaving only the heavy, humid atmosphere of mutual longing. The slide sat waiting on the table, but as Milena’s hand tightened its grip and her lips parted, it became clear that the data collection was about to become far more personal than she had ever planned.
