Fisting in the name of biology!

Daisy has a big biology exam coming up so she thought she had better study up on the female body with a bit of a practical. Soon she was only half dressed in her uniform as she rubbed and fisted her dripping pussy. This babe cums big for you and if she doesn't get an A for her trouble I'd be disappointed too. Enjoy the sexy and extreme masturbation from Daisy!
