It is unclear whether the nerdy girl did it on purpose, but she sure got some naughty benefits from participating in the silly challenge with her friend. The brunette student was determined to enter the stay inside for eight hours challenge because she wanted to look cool. The guy didn’t mind playing this game. So she grabbed his penis and began sucking it. Since he didn’t cum in her mouth, hope appeared that they might manage to fuck for eight straight hours. She just needed to keep his dick hard, and everything will be okay. One position after another, and the horny guy was destroying the chick’s delicious pussy. Even though she was a student and in pretty good sex shape, after four hours of fucking, the first signs of fatigue began to appear. But the guy was adamant about making it happen, so he took the initiative. The girl was on her back while the guy was doing all the heavy lifting. He fucked her pussy as best as he could. But he had to keep an eye on his dick. If it gets down, the challenge will be ruined. Sensing his weakness, the nerdy chick took over. They went upstairs, where she got on the stationary bike. She thought that some exercise would help them push through rough times. And she was right! Indeed, the guy’s dick was up and running again, drilling a hole in her delicious pussy. At about that time, she decided to moan and she didn’t stop until the end of the challenge. They found some interesting ways to pass the time, like making tea in the kitchen or working out in the home gym, all without his big cock slipping out of her tight pussy. Shortly after the eighth hour started, they went to the bathroom and fucked over there. The girl was bent over, looking at herself in the mirror and brushing her teeth, while the guy was destroying her from behind. The challenge was complete! After 8 hours of fucking she let him finally cum on her face!
