Ion kind of getting a little revenge on Zephyr for making him go out in a school girl uniform (https://inkbunny.net/s/2086539). Zephyr as a kid was bullied a bit for having a more feminine body while being a boy so it did upset him a bit, but in the end he actually quite enjoyed the experience
A couple of days after Zephyr made Ion go out on a date with him as his "girlfriend" for loosing a bet, Zephyr was getting ready to out with Ion again, this time with his older sister tagging along as she was in town. When Zuri arrived, Zephyr came to greet his sister, but was surprised to find her and Ion talking while Ion had Meeka's old school uniform on again from the days prior, while his sister was wearing her old high school one as well. Confused, Zephyr asked what all this was about and they both told him today was going to be a "girls" day out. Before Zephyr could ask what that meant, Ion and Zuri pounced on him, removing the clothing he was wearing and putting on him Zuri's old pink elementary school uniform, though the shirt was a little short, it still fit Zephyr fairly well, getting him to show off a bit of his midriff. Zephyr tried to protest going out like this, but was taken by the hand by his sister as the three of them left. They had a decent day out, with Zephyr mostly pouting during the whole experience, though he did get some winks and cute comments thrown at him. As they sat down to have dinner, Zephyr asked them why they wanted to embarrass him like this. Zuri responded that after Ion told her about the fun day they had, she though it would also be fun to have all three of them dress up in uniforms for their day out. Knowing that Zephyr wouldn't go with this willingly, they had to resort to a more forceful measure to get him to wear the school uniform, which they did apologize for. They never meant to embarrass him, just though he would get into it as the day went on. Zephyr did admit to them that after thinking about it, going around for the day like this wasn't all bad, and since Ion seamed to enjoy it this time and the last time, he apologized to them for kind of being a bummer on the day, as he realized that he didn't really all mind wearing this clothing. Ion and Zuri forgave him and told him that there was still some time left in the day to still have some fun, so they went out and enjoyed themselves for the rest of the evening just being a couple of "girls" on a night out
