After all, the longer he could experience it, the better results he'd get, right? "And if I don't like it, I'd get it over with faster, at least."

Jeff ran up to some stranger, who happened to be looking in the opposite direction, and pulled the back of their pants out, before just jumping right in. He didn't even care to take a look at *who* he chose before hopping in, he just went with it.
