My girlfriend, who I've been dating for six months, doesn't like sex much and is the honor student type. Her sister, who is the polar opposite of her and a bit of a scatterbrain, suddenly seduces me whenever we're alone... Her sister's raw and erotic body, she whispers sticky things in my ear, and even though she's right next to me, she seduces me with her bold outfits. We had sweaty sex, lots of squirting, and our bodies were wet, but we were still together for three days. I was already captivated by her sister.
