In the quiet of his apartment, Oscar explores the boundaries of his desire. His hands tremble slightly as he uncaps the glass bottle, its innocent appearance belying the carnal act he's about to commit. He spits into the opening, lubing it up before pressing the cool, hard glass to his eager hole. With a deep breath, he pushes it inside, gasping at the intense sensation. He begins to move, fucking himself on the bottle, his cock hard and leaking. His body tenses as he nears his climax, the bottle's smooth surface rubbing against his prostate, sending jolts of pleasure through him. With a final, shuddering thrust, he comes, the bottle filling with his hot, sticky cum.
