This is the 2nd debut work of "Sakura Ren," who has a "binkan" constitution that makes her cum vaginally right away! For the first time in her life, she challenges irrumatio where her throat is attacked with a piston! Hoping for skilled techniques, she volunteers for lovey-dovey training with all the teachers at school! It became a pleasure to have her throat ejaculated in! I'm captivated by the intense irrumatio that makes my stomach acid reflux! (5 corners in total / 5 throat ejaculations in a row!)
