Izzy chuckled gently up to her elder brother, her chest pressing tightly against his own as her lips grasped his, pink folds wrapping against the top of her own brother throbbing manhood; It was pretty huge, only one she had seen much bigger was her fathers, he wasn't the kind to hide his body from his family, and it seemed none of the family were really very shy when it came to nudity and the like, especially after what they'd all went through together. She gently kissed his lips, tasting him with her body, touching him gently and purring lightly as she slid down her body. Her lips lightly grazed his nipples, lightly licking one and placing the other in her mouth, suckling upon it until it became hard. She slid down his body, kissing his hard masculine abs, more perfect than most of his age. A little further and she found her prize, her lips opening a little wider than she'd hoped just to fit the bulbous head into her mouth. She moaned as she sucked the head in, his dick throbbing harshly against her tongue which slowly wrapped  around the veiny shaft, her right hand lightly grazing his balls as her left wrapped around the back, gently grasping his firm, hard butt.
