My stepsister was in my room, and she found my vibrator. She wanted to try it out, and I was more than happy to let her. I gave her some guidance on how to use it, and she was eager to give it a go. At first, she was hesitant and unsure, but with some coaxing and encouragement, she soon got into the groove. The vibrator was making her feel amazing, and she was loving every second of it. I could see the pleasure on her face, and I knew that this was just the beginning. We continued to play together, exploring new positions and angles, until she finally reached her climax. It was an amazing experience, and I knew that this was just the start of our sexual adventures together.
