Marian made a little gasp and arched against his mouth, her hand reaching down for his hair again. They didn't do this very often and it always felt a little alien, but it was certainly enjoyable. She'd never reached orgasm from just his tongue, always too self-conscious of herself to truly relax when he was down there, always wondering too deeply about what she looked like, tasted like, smelled like. Every time it seemed like she was getting close, she would think herself right out of it.
But still it felt good, and Marian rocked against him, trying to focus only on that it was Robin here with her, and not the man she had just been having sex with for three weeks.
