Leave the diaper.

You can't bring yourself to put the diaper on. You leave it on the bed and get dressed.

When you get back to Sarah's house, she's ready.

"Did you wear it?" She asks, patting your bottom to check for herself before you can answer. "You didn't." She pouts.

"I'm sorry." You say. "I couldn't do it.

Sarah doesn't get over her disappointment. She is distant through dinner. During the movie, you place your hand on her knee and start moving it up under her skirt but she stops you and moves it back to her knee.

You drive her home and she rather coldly says goodbye at the door. You kiss her but, while she doesn't reject your kiss, she certainly doesn't return it.

You get home to your apartment and find the diaper still on the bed.
