Since Rikana came to stay, my life has completely changed. It's less a growth spurt and more like she's in heat—morning and night, without regard for time or place, she demands my sperm, insisting it belongs only to her, forcefully milking me dry. Though I know I shouldn't keep doing this with my niece, her shockingly skilled techniques—learned from who knows where—make my cock react on its own, betraying all reason.
