In the dimly lit living room, the siblings' conversation turns heated. Celezte's voice trembles with unspoken desires, her eyes locked onto Gustavo's crotch. "Time doesn't scare me, Gus. It's the thought of not experiencing this... this feeling," she confesses, her hand inching closer to his groin. Gustavo swallows hard, his cock twitching at her proximity. "Celez, we can't... it's wrong," he protests weakly. But as she leans in, her breath hot on his ear, he knows he's lost. "Who said anything about right or wrong, Gus?" she whispers, her hand finally cupping his throbbing cock.
