Say yes.

"Yes." you say, trying not to sound as eager as you feel.

"Come on then." Tanya wraps the towel around you and leads the two of you back to Sarah's room.

Hanging from the front of Sarah's wardrobe are two dresses, identical except for the colour. One is pink, the other is baby blue. On the bed are two puffy white diapers.

"Lay down on the bed." Tanya directs you. As you do so, she takes out a box of baby wipes and hands a few to Sarah. "Here you go."

Sarah stands between your legs and teases you a little, running the cold wet wipe over your balls before wrapping it around your shaft.

Tanya watches as she unfolds one of the diapers. It's weird to have her in the room but you're too excited to protest.

Sarah moves the wipe up and down rhythmically until finally you squirt cum straight up. It lands on your stomach where Sarah quickly cleans it up with the spare wipes.

Suddenly very embarrassed that Tanya saw that, you cover your face. You feel her slide the diaper under you. She moves your, now soft, dick to point it down between your legs and then pull the padding up firmly between your legs. You feel it pressed against your stomach as she fastens the tapes.

When Tanya has finished diapering Sarah she observes "It looks like Daniel is a little worn out. Maybe you should have a quiet night in instead."

"Poor baby." Sarah says. "Did you want to stay in?"
