In the quiet of their shared home, Alex and Lisa's secret games begin. Alex, hidden from view, masturbates, his grunts barely audible over Lisa's engrossed gameplay. His cock throbs, and he can't hold back, cum exploding from him, coating Lisa's unknowing head. As he's about to confess, their mom's footsteps echo down the hall, sending Alex into a panic, frantically cleaning the telltale signs of his pleasure.
