Fluttershy loves peeing her wetsuit. Especially when she's had a lot to drink due to the heat of wearing a wetsuit on the beach in summer, and experiences immense relief in addition to the warm wetness. Applejack's glad she's enjoying herself, but averts her eyes while she's peeing, just in case looking in her direction for it might make her uncomfortable. But Fluttershy doesn't feel one bit nervous or ashamed of it anymore, and doesn't care if all her friends are staring at her. (Though she'd still feel different about wetting any other outfit in front of them, but if she did she could get over it) Her wetsuit always smells like pee but even Rarity doesn't mind, though she advised her to never mess in her wetsuit.
