Since you sold your soul to a Demoness, women are so attracted to you.
The babysitter you've always had the hots for would love to have sex with you, but she knows your wife would be very cross if this were to happen. ALL she wants is a little extra pay from you and everything will be fine. You have so much more money now what's the harm? The deal you made with the Demoness is really working out great.
