Being in a rush to leave the apartment to eat dinner because you got a reservation, so Toshinori wasn't able to use the bathroom because he forgot to keep track of time.
Arriving at said restaurant and ordering drinks. Going straight to ordering food, not minding if it'll take longer. Toshinori unable to help himself from sipping his drink when it arrives, soon remembering that he needs to go since he wasn't able to before
Allowing him to go because you wouldn't want to hurt the poor guy. But he ends up coming back nearly as quickly as he left because he can't go. Poor guy is too shy because the sound of people outside the bathroom makes him nervous
It's a family one: only one toilet and a locking door.
Watching and listening to him trip on his words, a sad attempt to ask if you could help him. Sighing and agreeing since your food is taking too long
Reaching the bathroom and locking the door, watching him pull down his pants and attempt to use the restroom. He lets out a little whine because he's trying, but can't because he's so nervous. What if someone knocks on the door? What if a line starts to form? Why won't it come out?
You shush him as you walk behind him, trailing your hands up his stomach and feeling him shudder in your arms. You talk gently to him, telling him to relax because he feels so tense. Putting your hand on top of his on his dick, placing your other soft on his bladder, making him move his other hand up to his mouth
He's muttering and whimpering because he has to go bad, but oh no... He doesn't want other people to hear him, not when it's about something as lame as having trouble to use the bathroom. The noises he makes are muffled as you press onto his bladder, shushing him because he's being too loud
Finally, his piss hits the toilet water as he relaxes, a stupid sigh leaving him because it was that much-needed
(Bonus :3c telling him midway through the meal that he owes you after you helped him... Poor guy knows you're going to be mean and have him hold it)
