Enters her with his finger
From Create Your Own Story
The lab assistant put his finger in his mouth, covering it in spit. That was all the lubrication that Audrey was gonna get. He slowly began to insert his fore finger.
Audery wriggled around under the restraints. The panic was clear in her eyes. However, as much as she attempted to buck her hips away from his prying fingers, it was futile.
The more she moved, the easier it was for his fingers to enter her forbidden hole. She attempted to shout insults at him through the cloth.
"If you keep moving, I will have to punish you." He threatened.
Audrey ignored his threats and continued to move.
It was a tight fit but he soon had two of his fingers completely inside Audrey's back passage. Her hole quickly adjusted to the size of your fingers.
As great as it felt to have your fingers in her not so tight ass hole, you knew you wanted something else now.
