The first person we were introduced to was her older sister, who is practically a NEET and a so-called "Morning Girl"! He may seem like an introvert, but when he gets into the kotatsu he acts boldly! Even though my girlfriend is nearby, she reaches out to my dick and gives me a handjob! Inserting it without permission while hiding in the kotatsu! While pretending to be calm, she presses her bare ass against him and seduces him into creampieing her! Maybe he had been building up his sexual desire for a long time, so he went for a second round without his girlfriend knowing!
