The amateur couple decided to have a romantic day by the river and had invited a friend along. The guy was constantly teasing the girl with her big ass, making her feel annoyed. But little did anyone know, this was all part of their kinky game. After some playful teasing, the guy managed to get the girl on her knees and started to take off her clothes, when the girl suddenly realized what was going on and tried to stop it. But the guy was too quick and managed to get her bent over and start penetrating her from behind. The girl's friend was caught off guard and didn't know how to react. But the girl, being a sport, took it in stride and started to enjoy it. The guy continued to penetrate her hard, ripping her clothes off in the process.
