Bobby and all his girls - along with Jason, Lisa and Jackie - slept in the motor coach, if they actually slept. We heard laughter and soft music until...late.When I finally checked the surrounding area and walked in through the back door, I saw no one. I walked into the bedroom and there was no one. I walked into the living room, turning lights off behind me, there they were.They had all the furniture pushed back in the huge front room. They had the mattresses from all four beds placed end to end. "Geeez, he's my best friend. I trust you two." I said, wanting her to feel the freedom to flirt with him when I was around.Once I blindfolded her and tied her to the bed, she loved it. I toyed with her, teasing her, talking to her about Hunter, knowing that would bring... a warm responds. I told her that I had shared with him all about how sexy and nasty she was in bed and about what an erotic pussy she had. "Sexy pussies are his downfall, especially if they are shaved." I told her.Then I told. All of a sudden, Alex pulled out and Sarah complained. He turned her so she was up against the glass facing me. I smiled as Sarah looked right into my eyes and Alex slid behind her. I knew it had to be tight in there because she was right up against the glass. I could tell when Alex entered her again because she grunted and smiled so big. Sarah was pushed up against the glass of the shower with her titts flattened. She just kept looking right into my eyes as Alex fucked her. I stepped closer. School had just finished for the year."It was just little things at first. Maybe it even started before we got to the cottage, during May and June," I said shyly."What little things?"I blushed. Looked down. "I don't know. Touches. Little smiles. Bumping into to me. You know ... her breasts," I stammered."She pushed her breasts into you?" I mean it wasn't obvious or anything. Just little things. Looks. Smiles. Words. I wasn't sure at first if--" What words? What did she say?" sis demanded as she.
