In the quiet of his room, a curious man decides to indulge in a unique form of self-pleasure. He positions a powerful vacuum over his eager cock, the hum of the machine filling the air. With a flick of the switch, he's enveloped in a warm, pulsating suction. His body responds, his cock throbbing and leaking pre-cum. He moans, lost in the intensity, his hips bucking against the relentless force. As his orgasm approaches, he increases the power, his body tensing, a cry escaping his lips as he spills his load, the vacuum greedily drinking it all in.
