Bella and Noah grew up side by side because their Dads were best friends and owned a fishing boat company together. They were so close they could finish each other's sentences and had never spent more than a week away from each other in their entire lives. They were more than best friends. Their parents said they were kindred spirits, two peas in a pod, cut from the same cloth. Where one went the other followed. He had always looked out for her and tried to protect her from getting hurt by guys that had bad intentions. She trusted him more than anyone else in the world. That's why when they went off to college together and she decided she wanted to experience sex for the first time, she couldn't imagine doing it with anyone else but Noah. She wanted her first time to be with someone special that meant a lot to her that she could trust. He refused at first because he was afraid it would mess up their friendship, until he found out that refusing meant she was going to do it with a guy that he hated instead. He was so protective of her that he finally gave in. The deal was, it was just going to be one time and they'd go back to being just friends after, like it never happened.
The problem was, they didn't think through all the consequences that came along with having sex with your best friend.
