*This is my very first story, just a quick fantasy. Please let me know what you think!*
Dean had a new girlfriend. He quite literally bumped into her on the street, and after he helped pick up her things he realized he should have gotten her number. She was fine as hell, probably 5'6 or so, long blonde hair, blue eyes and pink lips. She wasn't a small girl, which was great. Dean liked them fuller so he wouldn't feel like he'd break them if he got too rough. She wore a tight skirt and even tighter blouse, stretched across what Dean thought were C cups, if not more. When she smiled and thanked him for his help, he shivered and his dick twitched. He had a quick vision of her lips wrapped around him and hoped he would see her again.
In fact, he did see her again, and again and again for months. Her name was Lacey and she liked sex. Rough sex, anywhere and often. Usually they stayed at her place, but Dean didn't like leaving his brother, Sammy, home alone all the time. Yes, Sammy is a grown ass man and can take care of himself, but Dean still felt responsible for him. He was thrilled when Lacey accepted his invitation to move into the bunker with them.
Sam wasn't thrilled about the new living arrangement, but he had to admit Lacey was nice to look at. She wore short shorts and tight tank tops with no bra. Sam could always see her hard little nipples poking through the thin fabric. Lacey wasn't a private person and definitely wasn't shy about her body. Sam happened to be walking by the bathroom and realized Lacey had left the door open and he could see right into the shower. Sam leaned against the door as she rinsed the water from her hair. Pouring soap into her hands, she began rubbing it onto her body, gently caressing over her breasts, swirling her fingers around her nipples. Her lips parted and her head fell back as she squeezed, pinched and pulled at her own nipples. Her hands continued down her stomach and disappeared between her legs. Sam felt his dick stir and he grunted, which caught Lacey's attention. She brought her finger to her lips as she made eye contact with Sam and gave him a sly smile. Sam stood there while she wrapped a towel around herself. He was getting harder as she walked toward him and slipped out the door. Her eyes never left his and he swore she intentionally rubbed her body against his as she left. He shook his head to himself, she's his brother's girlfriend and here he is with a hard-on after spying on her in the shower. Later that night, he listened as Dean fucked her in their bedroom.
Days and weeks passed and Sam was in sexual agony. He could hear every time Dean and Lacey had sex, and if Dean ever left the bunker for a case, Lacey teased him mercilessly. She walked around in boyshort underwear and tank top with no bra. Sam was researching on the computer and Lacey came up behind him, leaning over to read the screen. Sam could feel her tits pressed against his back, and he groaned when she whispered in his ear. Another time he was in the kitchen and Lacey walked in wearing one of Dean's flannel shirts with nothing underneath. He turned around and she was right there, shirt unbuttoned. Before he knew what was happening, she had his shirt off and was pressed against his bare chest. She grabbed his hand and intertwined her fingers with his. "Lacey what are you doing?"
"Please, Sam. I want you to fuck me." Sam groaned and he could feel his dick hardening.
