Erika's smile widened at the sound of her name on his lips, and she met his hips with her own. She could feel the friction of his hips against her thighs as he drove upwards, the sensation only accentuating the feeling of his erection parting her inner folds.
With moaned quietly as their hips came together again. It wasn't a slow pace she set but a moderate one. He had her wound so tight she felt she would burst if they continued teasing one another -- and she was certain he wouldn't mind. She wasn't ready for that release quite yet, however -- she was enjoying riding the wave (and Chris) too much to give in just yet.
She honestly wouldn't have minded if he did roll them. This position had its advantages -- she could watch him from her perch, every expression and every movement he made, and she could feel the way he moved to meet her, their rhythm graceful and instinctive. But she also liked to be held, to be so completely entwined with one's partner...
She breathed out another moan, hands moving gently, searchingly over his chest between strokes. Her eyes remained on his with a smile, basking in the moment and in their mutual pleasure and just in him.
