Of 4 and then sitting nicely

Nervously, the woman glanced up at her partner. They had agreed to try something new tonight, and the anticipation was palpable. She felt his fingers brush against hers, and a shiver ran down her spine. They both knew what was about to happen.The room fell silent as they slowly undressed each other. Their eyes never leaving each other's. Once naked, they knelt down in front of the pile of clothes they had just discarded. Taking a deep breath, the woman leaned forward, presenting her ass to her partner. With trembling hands, he spread her cheeks, revealing her tight pink entrance.A sudden sting filled the air as he used a lubricant to prepare her. She bit her lip, trying to suppress a moan. As he worked his fingers into her, she couldn't help but arch her back in pleasure. The sensation was overwhelming as his hands roamed over her body.
