Zack breathed a sigh of relief as he walked in the door of his suburban home and immediately went to the bathroom. His balls were bursting; he had to take a piss. Normally he would have been fine, but the stress of the situation was getting to him.
He locked the bathroom door, laughed at his paranoia, but went and sat on the toilet without unlocking it. He sat down on the toilet and looked at his dick. The thread hadn't moved at all. He breathed a sigh of relief. He wasn't sure what was going on but at least in the privacy of his own bathroom he'd be able to figure things out. And, as he relieved his bladder, it didn't seem like it was clogging him up. Yeah, it felt kinda weird in there, and flapped around wildly as he pissed, but it seemed okay, so, after washing his hands, he reached down there and gave it a gentle tug, determined to get the knot out.
