You have difficulties with spanish so your teacher proposed to give you private lessons.

Little did you expect him to be so bold as you were both alone in his classroom, trying to make you do an exercice you didn't get.

He purposely unbuttoned a few buttons on his shirt to show the beginning of his pecs because 'it was hot', and while you were flustered and red, he leaned close to your face.

"¿Por qué te sonrojas, querida~?" He smirked.
