True lover
I've been married for 10 years to a man that does love me and make me happy, and generally satisfies me in bed. I've never told this to anyone, but I've had one true lover since I was 15, one that doesn't just satisfy my sex needs, but makes me utterly crazy in bed. It's my older cousin, whom I lost my virginity to, and is still (and probably always will be) the best lover I've ever had. He's nearly 50 now, and is still the rough, muscular, manly beast that can leave me shaking in bed like a little puppy. He has the perfect amount of chivalry and perversion to either make love to me or fuck me like a whore, and that's what I love about him. I could never quit him, not even after getting engaged and then getting married.
I had sex with my now brother-in-law before he married my older sister. Recently I got him to fuck me again like he used to. He likes me to talk dirty, real slutty, and I let him treat me like a whore which I know that my sister doesn't do for him. I don't want to steal him from her, just fuck with him every week or so.
