Ever since his ‘moment’ with Cheerilee, something developed in Calculus Crunch, an alter ego named Dr. MILFlove. Though in recent times, that part of Calculus had been swept under the rug, waiting for the day he’d be set free. That day soon came when Calculus, fueled by alcohol, had a one night stand with Rose Oak, his own mother. That broke MILFlove’s chains and set him free. Now, he’s able to influence Calculus’s mind if and when he pleases, for whatever he wants.

Based on this story.
