"Let's do something more fun!" A serious study group turns into a lewd penis research club! Students who are tired of studying release their stress and sexual desire through their vaginas... HUNTC-285

Although my classmate asked me to tutor her for the exam, she was interested in my penis but wouldn't cooperate. She tempted me by showing off her panties and breasts! She even spontaneously developed a lesbian image! Seeing her like that, I couldn't concentrate on studying, so I had to join in! As a result, they happily measured my penis, played with it, and observed it to their hearts' content. When they reached their peak of excitement, they penetrated me!
