Sam found the zipper on the back of the thing and slid it down. Once it was off her shoulders, he helped himself to a mouthful of her amazing, perfect breasts. Really, and truly. Anne had the most glorious pair of tits he'd ever laid eyes on. He was half tempted to show them off to Dean, but that would be weird.
His tongue flicked out to taste a nipple, his teeth carefully grazed her there. He suckled on her, taking a generous amount into his mouth and laving at her with his tongue. Sam was and had always been a boob guy. While his mouth was on one, his big hand was less than gently palming her other one, sometimes letting the nipple roll between his fingers.
