Masturbate

Lying in bed, Catherine's fingers eagerly undid the buttons of her black silk nightgown. She slipped the garment off, revealing her perfect round breasts and the erect nipples that poked out, begging for attention. Unable to resist the urge any longer, she started to rub her swollen clit, her other hand finding its way to her ass crack, teasingly inserting a finger inside. The feeling was unbearable, yet exquisite. She moved her hand faster, her breathing becoming more labored as her body approached its climax. Suddenly, a knock on the door shattered the silence, breaking her focus. Who could it be at this hour? Filled with both fear and anticipation, she didn't stop even though she knew she should. Finally, as the 2 minutes and 9 seconds passed, she let out a long moan, her entire body shaking with a mixture of pleasure and relief.
