Under the soft glow of his desk lamp, Brazilian genius Genio engages in a debate - with himself. Clad in nothing but his boxers, his mind wanders from celestial bodies to earthly desires. His cock stirs, pressing against the cotton, seeking freedom. Genio obliges, pushing his boxers down, his hard, veined cock springing free. He grips it firmly, his hand gliding up and down the length, his thoughts a whirlwind of equations and fantasies. His strokes become more insistent, his body tensing as he nears his climax. With a low groan, he spills his load, his cum coating his hand, a silent confession to his solo indulgence.
