Doing it all over again with his second girlfriend, he got more chances to level up his lock. He also got more adventurous when it came to positions. It went into overdrive when they got older. When Matt got a bit bigger, Chester was finally able to deepthroat him. He only did it once a week, but it was more than enough for his friend. There was nothing complicated about it. Chester was a Lock. Once Matt's cock got down his throat, the Lock activated and Matt blew his load. Chester's Lock got stronger each time it happened. The many upgrades cycled. First, the White Lock granted a tenth of an inch in length. Then, it granted a twentieth of an inch in girth. Next, it was a 1% increase in sperm count. Finally, it was a 1% increase in sperm efficiency. By the time he had been dumped by his first girlfriend, he had grown 2 inches in length and 1 inch in girth. Chester had big balls filled with cum. His swimmers were primed and ready to get any woman pregnant. By the time he turned 17, he was a level 31 Lock. It had grown bigger and become a work of art with how ornate it was. It was noticeable.
Eventually, his mother had to sit him down and tell him to slow down. She did not want him getting hurt. She definitely did not want her son to get someone pregnant. The prospect of a child before wedlock or graduating high school would ruin his life. They were too poor to take care of their own affairs. Raising another child in poverty would be terrible. Due to that, he stopped fucking his girlfriend for a bit. She was already totally obsessed with him due to him fucking her. With his Lock so levelled, there was no risk to him. At level 31, everything was better. Now, he that he had fully mastered his powers at level 20, he could choose which aspect to grant once his Lock activated on penetration. The White Lock now granted 3.1 inches in length, 1.55 inches in girth, 31% increase in sperm count or a 31% increase in sperm efficiency. The efficiency was the easiest option. He would not suffer from a monster cock balls that would get in his way. He would not need to clean even more disastrous loads when cumming. His sperm getting someone pregnant was fine. There was their Plan B pill.
Feeling his abs tingle every activation, he would look down to see his Lock. It jutted out 3 inches from his skin. It glowed with a bright light every time. His girlfriend was in his class. She was also affected by the Lock. Her fertility was through the roof and her breasts were now double D's. Chester had a 9 inch long cock and it had 3 inches of girth. Matt had 7 and a half inches and 2 inches of girth. That was thanks to the power of the Lock. While Matt was not the biggest or most athletic, that cock shocked anyone who saw it in the locker room or in his bedroom. If his dick size was a shock to people, Chester's massive member made people's jaws drop. He knew the scores now. It was what it was. Even with how poor he was, he could make money with his powers. There were tons of people that were having problems with fertility. He could make money using his Lock. Eating out a woman or deep throating a man was all he would need to make their fertility rise by 31%. That would would be enough to get some children out. He could make $250 a session. Medical treatments cost way more.
