Candlelit library slow grind with choker tight

In the moody candlelight, she presses her hand to her stomach while sinking down onto his thick cock, her hips rocking in a slow, grinding circle that makes her full breasts shift with every movement. The choker sits tight against her neck as she focuses forward, taking him deeper with each controlled descent. She had slipped into the library in her soft sweater to read alone, but the empty shelves and dim glow pulled her to strip bare and mount him on the chair before the night ended.
