If the first thing a boy does when he get a magic power is to commit a serious sexual assault (have sex with someone unable to stop him), why do you describe his sister as being "oversexed"?

You might be thinking of Young Thinker's trilogy "The Rock". In the first story, teenaged siblings gain the joint power of stopping time, go to a mall where they first have sex with each other, then molest and frame a schoolmate in retribution for a past attack. In the second story the boy does go back and forth from the mall on a bicycle while time is stopped, though.
Unfortunately, Young Thinker removed all of his stories from the site a few years ago. You might be able to find some of them in an archive, but it would be tricky.
