This was clearly sex, lust, whatever you wanted to call it. Hermione realized as she looked him in the face that she wanted to slap him and suck him off and she would be mortified if anyone ever found out. "Promises, promises, Malfoy," she said with an eyebrow raised.
She laughed, she knew that if Lucias Malfoy caught them in here he would probably kill them both, but Hermione knew how pretty and smart she was and didn't need Draco or anyone else to verify it. "Be better to keep this between us Malfoy, no running your mouth in the Slytherin Common Room," she pumped his cock with her small hand and swirled her tongue around the head, "not that you would want anyone knowing, I'm sure."
Hermione didn't know if he really just wanted to hear him talk dirty or if he didn't know, so she tested the waters, "ever gone down on a girl, Draco?" she asked, "I have." She did if for pure reaction value, she didn't care what he thought about her and she knew it made most boys extremly horny to think about girls with other girls.
