During summer break, I returned to my hometown and reunited with my cousin Shion after a long time. Her body had matured into that of a woman—her big, juicy breasts and plump ass swaying softly, radiating an irresistible, honey-like allure. Still innocent and childish at heart, she carelessly flaunts her huge tits and panties in front of me. Watching her like this stirs up dark, obsessive fantasies within me, igniting an uncontrollable lust. I give in, overpowering her, and spend the entire summer break lost in a frenzy of relentless sex. Every time she whispers, "Don't tell anyone about this," my cock instantly throbs with full hardness, and we sneak away to fuck behind our parents' backs. This is a full-blown incest drama brought to life.
