She lies on the bed, naked and vulnerable, as he approaches her. He starts by kissing her neck, then moves down to her breasts, sucking on her nipples until they're hard. She moans with pleasure as he slides his hand down her body, his fingers tracing circles around her clit. He then moves his hand down to her ass, slowly inserting one finger, then two, and finally three. She gasps as he starts to move them in and out, deeper and deeper. He adds a fourth finger, stretching her open, and she cries out in pleasure. He continues to finger her ass, his other hand still playing with her clit, until she can't take it anymore and comes hard. He withdraws his fingers, and she collapses onto the bed, spent and satisfied.
