Tentacity, with an eager grip and a steady hand, brings Sven's thick, throbbing cock to full attention. He attaches the Twincharger, a sleek, powerful machine designed for male pleasure. The device hums to life, its rhythmic pulsations coaxing Sven's balls to tighten. Tentacity watches, entranced, as Sven's cock swells, veins bulging. The room fills with the scent of pre-cum and the sound of mechanical pleasure. Sven's breath hitches, and with a final, intense contraction, he explodes, his hot, creamy load painting his abs in a satisfying handsfree cumshot.
