今日はちょっと暑いみたい。もっと薄着で出かければよかった…ん?中に何か着てないはずなのに、なんで中の服の生地がこんなに変な感じがするんだろう?
あっ、こんな女の子のビキニを着て出かけた記憶なんて絶対にないんだけど、うーん…
Looks like it's a bit hot today. I should’ve worn less before heading out... Huh? I don’t think I’m wearing anything else underneath, so why does the fabric of my inner clothes feel so weird?
Ah, I definitely don’t remember putting on this girl’s bikini before leaving the house, ugh...
