Yes, and she is curious

She looked up at that moment and gave me a smile and said, “It’s really no big deal. I am not upset or anything. I was just so surprised. I didn’t know what to make of it.”

I was more relieved than I realized I would be as I said to her, “Good, it won’t happen again or anything. I promise you.”

The look on her face was one that led me to believe she had something on her mind still. I asked her, “So is there something else?”

She turned bright red again and said, “Well what was on those tapes, umm, you know, is that the way it really works?”

I was dense for a moment as I said, “What do you mean exactly, how what really works.”

“Oh, god this is so embarrassing, I mean how, you know, sex really works.”

Suddenly it dawned on me what she was asking. I fired a question back at her, “Are you a virgin?”

“No,” she answered quickly. “But I have only done it once. It was last summer in the back of Greg’s car. It was dark and over so fast I didn’t really know what happened. He just was inside me and then a few seconds later he was done. Then when I watched the tape today they seemed to go on forever, but the girls just kind of took it. They didn’t really react. And then the men pulled out and did it on their faces, or boobs. I mean is that how you do it. Is that what I should expect when I do it with a guy?”

I looked over at my sexy sister in law and looked at her big nipples poking out through her thin t-shirt. I looked at her expectant face and I thought about my rapidly hardening cock. I was so torn about how to take this situation to my advantage. She was practically asking me to guide her through sex, and I wondered how far she would let me go, and if she would tell my wife.
