Yuka is a newly appointed female teacher with a bust of 98cm and an H cup, a lewd body that is out of proportion to someone who stands in front of the podium. Her big breasts are so popular that they attract a lot of attention from students at school, and she even shows off her squeezing habit, gently wrapping her favorite dick in her elastic cleavage and making it feel good. Please enjoy Yuka's naked, instinctive ``nasty sex'' that she doesn't show at school.
