MSQD-006 Karina Tanida in a confined oral sex session, 4K

The video opens with Karina Tanida in a bare room, wearing a school uniform, and the camera stays close on her face and mouth. She is bound and blindfolded for most of the runtime, with a man directing her through a series of deep-throat exercises. The 4K footage is sharp, and the sound is mostly her gagging and breathing. There is no plot beyond the setup; it is a straightforward solo oral scene with light SM elements.
