It took you a little more than a month to finally track Coach Allen down. He had changed his name and using as much of your identity as he could, he had created for himself a new life. He got a job coaching at a new school and moved into a decent apartment. Some of the identity he had stolen from you included your looks. He didn't look exactly like you but he now had your hair color and your eye color. It was obvious that Coach Allen had learned a few spells during his time as Kevin's jockstrap.
In the mean time, your cock had grown to nearly twenty feet (600 cm) long. You couldn't just let it drag behind you anymore. You had to role it up and carry it in a wheelbarrow or cart. You had also learned how to walk sideways so that you could avoid facing your target because you didn't want your super-long, rolled up cock to suddenly harden into a nearly twenty foot long pole. Once you were erect, it was nearly impossible to walk.
People had noticed you by now. Cops had questioned you. But after they harassed you a little, they all became overwhelmed by the sheer freakishness of your situation, so they all just wandered away and left you alone. Sometimes you had to pursue them a bit to get any help from them and then they would help you as quickly as they could so they could get away from you as quickly as they could.
Fortunately for you, when you finally found Coach Allen, he was asleep on the couch in his tiny apartment. All you had to do was try to put Coach Allen on and he would change into your jockstrap. Unfortunately, that didn't turn out as simple as you thought it would. The moment you started to put Coach Allen on, your cock erected. It slammed into the wall and continued stretching out which forced your cock to change direction, dragging your poor cock head painfully across the wall until it found it's way into a corner between two walls and the ceiling in the kitchen. On the other end, your cock pushed you until it slammed you into the corner near the door of the living room with your butt smushed into the corner between two walls and the floor. And even then, it wasn't enough room because your cock continued trying to stretch itself into a hard, straight, nearly twenty foot long pole. You were essentially wedged into Coach Allen's apartment until able to move your cock as both ends of your cock hurt from the pressure of trying to erect. The middle of your cock was also rubbing painfully against the bar.
But at least you managed to turn Coach Allen into your jockstrap. There he was stretched out around the entire length of your cock. You decided to celebrate your victory by pleasuring yourself as much as you could. After you shot gallons of cum, drenching Coach Allen and his kitchen, your cock finally relaxed and you could get up again.
You felt a little sorry for Coach Allen. You were angry at him for dragging you into this fiasco but you understood that after what he had been through, you might have done the same thing to some other delivery guy. If you could have, you would have let Coach Allen escape. But when the decision was between you and him, you decided he should be the jockstrap and you should be the one to escape.
The trip back to Kevin was easier. With Coach Allen as a jockstrap, he was better able to bundle up your ridiculous cock. You still needed a wheelbarrow or cart for long distances but Jockstrap Allen made it possible for you to walk five feet without a wheelbarrow or cart, as long as you could rest your cock every five feet. You also no longer had to worry about sudden erections and you could walk semi-normally again. Fewer people harassed you as well since you were at least decently covered by Jockstrap Allen despite the huge bulge Jockstrap Allen was forced to contain.
The problem was that your cock didn't stop growing. Kevin had cursed your cock to continue growing until Coach Allen was Kevin's jockstrap again. You had to hurry back to Kevin and hand Jockstrap Allen back to him as fast as you could before your cock became even more of a burden.
By the time you got back to Kevin, your cock was more than twenty feet long. You took Jockstrap Allen off and handed it back to Kevin. Then you asked, "Will you remove the curse now?"
Kevin said, "Sure." and snapped his fingers.
You breathed in happily and expectantly looking forward to your cock shrinking. But nothing happened.
You asked, "Wait, isn't my cock supposed to shrink back to a normal size?"
Kevin said, "Why would it do that? I said it would keep growing until I had my jockstrap back. I never said anything about returning it to normal. Now if you will excuse me, my business with you is finished."
Kevin grabbed you and started shoving you out the door. You fought back of course and physically, You and Kevin were an even match. But Kevin had magic on his side and You had your cock as a disability so slowly you both progressed toward the door.
After he threw you out and slammed the door in your face, he shouted, "Have a nice day."
There you stood, outside his door wearing your shirt and shoes but nothing else between your waist and ankles. You thought about revenge. You thought the possibility that you could free Jockstrap Allen and the two of you could team up against Kevin. But how? If you didn't do something, you were doomed to spend the rest of your life with a more than twenty foot pole attached to your crotch.
