Step-sister shares intimate details of sexual encounter with my boyfriend

My step-sister came over the other day and we were just hanging out when she started talking about her sexual encounter with my boyfriend. She was telling me all the intimate details of their encounter and how he had taken her in his room and had his way with her. She was saying how he had taken off her clothes and had been sucking on her nipples and then he had been fucking her hard. She had moaned so loud that everyone in the house could hear her. She had even told me that she could feel his dick inside her and how it had made her feel so good. I could tell that she was really enjoying talking about it and I could see that she was turned on as well. She was rubbing her pussy while she was talking to me and I could see that she was really close to coming. I could feel the excitement building up inside me as I listened to her.
