My junior, Mia Kouki, has been getting unusually close to me lately. She intentionally whispers work updates in my ear and touches me frequently during conversations. I usually just ignore her, but one day, she sneaks under my desk and starts playing with my crotch. Knowing 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 making me cum in her mouth with loud slurping sounds in the office, she becomes even bolder in the locker room, exposing her huge tits 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.
