Meaning

The word tsura 面 means "face," while fukure 膨れ means "swelling," "inflating," and can also refer to someone "puffing" out their cheeks, or someone "being in bad humor," frustrated, a main reason to puff out one's cheeks..

• hoppe wo fukuramaseru
  ほっぺを膨らませる
  To make [your] cheeks swell. (causative sentence.)
  To puff out [your] cheeks.
  • fukuramu
    膨らむ
    To swell. To inflate. To expand. (intransitive verb.)

The word fukure 膨れ is the ren'youkei 連用形 of fukureru 膨れる, whose is similar to fukuramu 膨らむ, but the usage seems to be different.

The difference between fukureru 膨れる and fukuramu 膨らむ is that fukuramu 膨らむ is used generally, while fukureru 膨れる is used when tends to be used when the "swelling" is unwanted, is a bad thing.^{[＜膨らむ＞と＜膨れる＞の違いは何ですか。 - detail.chiebukuro.yahoo.co.jp, accessed 2020-05-20]}

If your belly gets bigger because you ate a lot, that's an unwanted effect, so fukureru is used. In the case of pouting, people pout when they're angry, so it's a bad thing, hence fukureru.

According to some dictionaries, however, both words are synonyms in the swelling sense, but fukureru also has a separate sense: "being in bad humor," which comes from the idea of puffing out one's cheeks.^{[膨れる - 三省堂 大辞林 第三版 via weblio.jp, accessed 2020-05-20]}
