Use the toilet.

You're not so invested in this movie that you'd rather wet yourself than miss a few minutes.

"I won't be long." you tell Sarah, getting up.

"Fine." Sarah doesn't hide her disappointment at all.

You make your way down the row of seats, your diapered butt only inches from peoples faces.

Reaching the men's room, you approach the urinal and unzip your fly. As you go to pull your dick out, your fingers hit plastic and you realise that's not going to work.

Quickly ducking into a stall, you lock the door and pull your pants down. You try to pull the diaper down but it doesn't budge. You're **** to undo the tapes.

The sound they make as you rip them open seems deafening. You're certain that everyone else in the men's room knows what you're doing.

You empty your bladder and re-tape the diaper. You don't do a great job of it. It is lopsided and loose but you doubt you could do any better without laying down so you pull your pants up.

Nervously, you step out of the stall, expecting everyone to be looking at you but nobody is. You wash your hands and make your way back to Sarah. The loose diaper shifts uncomfortably as you walk.

"You missed the best part." Sarah complains as you sit back down.

Soon the movie is over and you drive Sarah home. She still seems annoyed with you as you walk her to her door, kiss her goodnight and leave. Is she really going to hold it against you that you didn't wet yourself?

Back at your apartment building, you are just about in your apartment door when a someone taps you on the shoulder.

"Hey Daniel." It's Kate. She lives a few doors down from you.

"Hi." you say, unlocking your door.

"I don't want to embarrass you." She says. "But are you wearing a diaper?"

"What?" You pretend to be shocked by the question. "No."

She pats your bottom. "I knew it."
