Stop her

All of a sudden things are making you very uncomfortable.

Oh my God, you think. I just got eaten out by Emily's mother. What the fuck is wrong with me?

You shake your head and push Liz gently away. You get to your feet and go stand on the opposite side of the room, away from Liz Fowler. "Sorry, Mrs. Fowler," you say quietly. "I just don't feel good about this anymore."

Liz grimaces. "I'm sorry, honey," she says. "I don't know what I was thinking."

"It's fine," you say. "I wanted it too." You just want it less now, and you certainly don't feel great about your decision to 'indulge' in sex with Liz after the fact.
