My junior, Mia Kouki, has been getting unusually close to me lately. She intentionally whispers work reports in my ear and talks with plenty of body touch. I usually ignore her, but one day, she sneaks under my desk and starts playing with my crotch. Knowing that I can't make a sound while working, she ravenously sucks my erect cock, whispering with a beautiful voice, "It's gotten so big in a place like this, hasn't it?" After I cum in her mouth with loud slurping sounds in the office, she becomes even bolder, exposing her huge breasts in the locker room and inserting my cock into her soaking wet pussy. As she escalates, she invites me into the women's restroom... This AV is presented with ASMR binaural recording, earphones or headphones are highly recommended.
