In the dimly lit room, Extremboy51 meticulously prepares his equipment, the air thick with anticipation. He unrolls the 16mm dilator, its smooth silicone glistening under the soft light. He applies a generous amount of lube, his breath hitching in anticipation. The E-stim device hums to life, sending gentle pulses through his body. He takes a deep breath, positioning the dilator at his entrance, and begins the slow, torturous insertion. His body tenses, then relaxes as he focuses on the intense sensations coursing through him.
