My ex-girlfriend told me about how when she was younger she had her mouth around her brother's cock. They weren't old enough to really realize what was going on but honestly I really think she thought about giving him head all the time. Should have asked her if she could swallow with cock while I fucked her from the back. And we could have both finished in opposite ends of her at the same time. Her telling me how amazing his cock and spunk tasted. Either with her brother or her dad. I would have loved to hear her slobbering all over her daddy's cock
