Redhead teen is fucked by her best friend in a park

My redhead best friend is a sucker for public sex. She tries to convince her boyfriend to take her to the park and fuck her, but he disagreed. So she decided to ask me her best friend. At first, I was reluctant, but I have always wanted to fuck her sweet pussy, so I agreed. We got to the park, and she sucked my cock before I proceeded to fuck from behind.
