In the first installment of "I Know What Chu Did Last Summer," Lulu Chu and Kimmy Kimm, clad in their school uniforms, engage in a sultry, moaning-filled session on the desk. Lulu, the Asian nerd with glasses, finds herself in a fantasy come true as Kimmy, the popular cheerleader, seduces her. With Kimmy's skirt riding up, her wet pussy is revealed, and Parker Ambrose, the jock, walks in, his cock hardening at the sight. Lulu, confident and teasing, invites him to join, promising a wild, loud-moaning threesome that none of them will forget.
