Get undressed.

You strip down to your underpants while Sarah watches, holding the diaper.

"Underwear too." She says with a smile.

You'd looked forward to being naked with Sarah but not like this. With a sigh, you pull down your briefs and step out of them.

"On the bed." She directs you, cheerfully. Her mood has significantly improved.

"I'm glad you're enjoying this." You say, sarcastically, as you lay down.

Sarah unfolds the diaper and approaches you. "Bum up."

You do as you are told and she slides it under you. As you lower yourself back onto the bed, you feel the padding beneath your bottom.

Sarah wastes no time in pulling the front of the diaper up firmly between your legs and fastening the tapes. After fiddling with the leak guards a little, she offers her hand to help you up from the bed.

You turn to the full-length mirror on her wardrobe door. You look ridiculous. "Can I take it off now?"

The question instantly dampens Sarah's mood. "I'd rather you stayed in it for a while."

"Can I put my clothes on over it at least?" You ask.

"You can." A naughty smile forming on her face. "Or I could take mine off."
