They took off their shoes so they couldn’t desecrate the daifukuKurumi: thinking about food 😋
Momiji: thinking about somethin else
It messes the texture, I don't think daifuku is this durable. But it sounds kinda lewd to let Kurumi eat remains of daifuku groped by Momiji, huh...... I mean, groping a daifuku does not consume the daifuku right? so they could buy one. have momiji grope it until she's satisfied and then kurumi can eat it.
