絶対に声を出してはいけない状況で突然手を出されバレたら大変なのにずっとしてなかったからカラダが敏感に反応してしまいガマンできずに声を殺してイキまくるッ！！
It's a situation where you absolutely can't make a sound, and if you get caught, it'll be a big problem, but since it's been a while since you did it, your body reacts sensitively and you can't hold it in, so you cum hard while trying to suppress your voice!!
