Lauren knew that he should have worn a condom, but he'd begged her for one time without. She knew the risks, gave in eventually, and for most of the l...st hour, Lance had fucked her from behind bareback. His cum splashed into her hole and he held against her before finally withdrawing and walking off to the bathroom.She laid there a moment, exhaled resignedly, wished he'd have at least asked her if she wanted to cum. Lauren appreciated his stamina, no doubt, but the monotonous hammering had. She had a gorgeous face and body. She had curves to die for, blonde hair, and bubble-ass that looked like it was about to burst right through her jeans. She was wearing skinny jeans, and a top that showed off some skin.

She maintained that by dancing with her, I had brought her out of her shell, changing her from a shy, ugly wallflower to a popular girl with a new outlook. I argued that she had done more for me by sending her brother to change. My husband figured it out through my texts, and I admitted to it. I told him that I was sorry but I felt this biological urge to have sex with the father of the baby inside of me.After a week of fighting and sleeping in separate rooms, my husband told me that he would rather know about my relationship with my ex than to have me cheating. It was at that point that my ex and I started openly dating and sleeping together frequently. My husband was jealous and mopey at first, but in time he started.
