As Chad sat there in front of his locker with a towel wrapped around his waist, and breathed softly, Bruno came up behind him.
Chad was relieved that his cock was no longer being rubbed over his naked male classmates' bodies. But he was sweaty and exhausted from the sexual workout he just had. As soon as he caught his breath, he had to go into the shower room to retrieve what was left of his manhood.
He was about to stand, when Bruno from behind him hung the empty string around his neck and over his shoulders. Then he felt Bruno's flopping cock slap against his bare back. The detached ends of the cord brushed against Chad's nipples. Chad froze. He stared at the loose rope.
"Sorry, Chad, we used up all your soap," Bruno said slapping Chad's back. As he spun away, his cock head swiped across Chad's back. It punctuated the absence between his thighs that Chad felt.
If Chad had looked at Bruno, he might have suspected that the grinning idiot was lying. But all he could do was look down, first at the ends of the cord from which his cock and balls had hung only 15 minutes ago, and then down at his lap where the towel sagged instead of bulging. He felt so empty.
Bruno headed back to his locker, where he had already stowed that unique manhood shaped bar of soap after removing the string.
