The week dragged on in a haze of stolen moments and simmering tension. Koo played the good girl—studying for college, helping Mina with dinner, all while sneaking quickies with Tae whenever possible. A hurried blowjob in the garage before he left for work, her pink lips wrapped around his thick cock as she swallowed his load with a wink. A late-night finger-fuck in her room when Mina was asleep, his hand clamped over her mouth to muffle her moans as she squirted on his fingers. Tae kept her satisfied, pounding her pussy raw in the home gym one afternoon, whispering, “This cock’s all you need, slut—don’t forget it.” Koo nodded eagerly, her body addicted, but her plan burned in her mind. She’d flushed her pills days ago, her fertile womb ready for the taking.

By Friday, excitement bubbled over. Koo bounced into the kitchen, backpack slung over her shoulder, dressed in a skimpy top and shorts that hugged her curves. “Mommy, I’m off for that weekend trip with the girls! Just a quick getaway—spa stuff, shopping. Be back Sunday night!” She hugged Mina tightly, acting all bubbly and innocent, her massive tits pressing against her mom.
