Beau Style, Dropkick, Outil, Delta (back, at the wall and window), Shatter, and Sirius Canis Major (front, the ones playing a card game) forced to be locked in a room and not at all allowed to be let out, not even to go the bathroom, hence the reason they're wearing diapers but of course they're trying not to think about and only use them if they really have to go. Luckily, the room had things for them to do so that's why they have entertainment.

While Sirius and Shatter are way to busy playing their card game to notice anything happening around them. Beau Style, Outil, and Delta are noticing Dropkick's discomfort due to the now strong urge to pee. Since he and or anyone of them aren't allowed to use the bathroom, he was in for embarrassment. He acknowledged the padding but he didn't want to wet in them and has been trying to hold it for as long as possible, now it was almost at the limit. Delta was reading a book and stopped reading when the situation started happening. Beau Style is only watching as he can't do much. Outil is trying to comfort him and telling him that they wouldn't mind him using them, with the fact that they're all wearing them in the first place. Dropkick listens to Outil's advice and gives up trying to stay dry. He takes his front hooves off from the front of his diaper and stands back on all fours. Outil steps back and the other two watch him in pity since he's in such a uncomfortable situation right now. Outil reassures Dropkick again that it'll be okay for him to relieve himself and that they'll understand. He hesitates at first but than spreads his hind legs and his legs shifting more to the back, so he was in squatting position but his legs were hardly bent, and tail automatically raising and flipped to the side. Once slightly squatting, he relaxes his bladder muscles and begins to feel relief. Beau Style, Outil, and Delta feel bad for him and watch pitifully. It was then when Shatter and Sirius knew what was happening and they don't exchange any words. Dropkick didn't care right now what they thought and was happy to be able to get what he needed. His diaper starts to get saggy due to how much pee he was emptying out from his overly full bladder. His stream was long and felt like forever, he couldn't stop going. He spends almost two minutes in that position and the rest were shocked how badly he had to go. The stream started to dry up two minutes later and it was when he was fully finished that he acknowledged his extremely droopy diaper. It was so bad that he could hardly move. Thankfully, none of the ponies had to sit in their waste and were able to change out of the diapers they used. With two Unicorns, diaper changes weren't two hard since they could use their magic to do it.
