Elena pinned Marcus against the silk sheets, her eyes flashing with sharp wit and unyielding desire. "Darling, that condition of yours—oligoasthenoteratozoospermia—makes it impossible for you to get any woman pregnant," she purred, her fingers tracing the hard line of his jaw. "Your sperm are pathetic weaklings, too few and too feeble to swim far enough to reach my egg."
Marcus groaned, his cock already straining hard against his pants as her breath teased his ear. "Elena, you're killing me with that science talk."
She laughed, low and seductive, straddling him fully. "Oh, it's no joke. Those deformed ones? Picture them with two heads, like grotesque little mutants wobbling uselessly. They can't even hold together—they're weak, dying within seconds or falling apart from the currents of a woman's fluids. My pussy's warm, wet depths would drown them instantly."
Her hand slid down, gripping his throbbing cock through the fabric, making him pant. "And vulnerable? Absolutely. A rival male's fertile sperm would sweep in like warriors, outswimming and outlasting yours every time. They'd claim what yours never could." Elena's voice dripped with horny confidence, her strong thighs squeezing him as she leaned in for a fierce kiss.
Sweating already, Marcus bucked up, but she held control, shedding her clothes to reveal her dripping pussy. She teased his ass with a playful slap, then took his cock in her mouth for a slow, teasing blowjob that left him gasping. "Feel that? Your weak seed stands no chance against real competition."
Panting, she mounted him, guiding his hard length toward her slick entrance. The air crackled with tension, bodies slick and eager, building to an explosive clash where her dominance would shatter all rivals.
