You can sense her vulnerability and fear, yet there's an undeniable desire in her eyes when she looks at you. You feel your heart racing, your throat drying up at the thought of taking her virginity in this intimate way.As she closes her eyes, preparing for the pain, you kneel down behind her and place a reassuring hand on her lower back. Your cock twitches in anticipation as you whisper soothing words in her ear. You slowly insert a finger, feeling her tightness squeeze around you. Her breath hitches, but she doesn't pull away. You slowly work your finger in and out, getting her used to the sensation.When you're sure she's asleep, you sneak out of the room.
