The head of my penis touched her pussy lips and she raised her hips to accept me. Had she forgotten how big I was? It had to be gentle, or I would hur... her. She pulled me on top of her and my cock penetrated her, she cried out with a mixture of pain and pleasure as it slid deep within her. She wrapped her legs around my waist, wanting all of me, her nails digging into my back and drawing blood. I pushed it in deeper before slowly withdrawing until the head was almost out, then easing it back. "She's my sister," I explained."That's no fucking reason," said Jacquie angrily. "Me and Jane don't fucking do everything together, do we?"Jane and Jacquie both had something of a temper on them, especially Jane, so I didn't want to give a reply that could set them off. Although they were usually quite calm and even gentle, there were occasions when one or the other would fly off and I'd be caught between the two sisters yelling and screaming at one another, usually in English but sometimes in. You need to read a bit of history. Specifically anthropology and a study of more primitive human cultures.I know that might be confusing, but I told you about the fact we have a Sergeant who was a professor of marine biology. We also have a young man who was working on a doctorate degree in anthropology. His final thesis was going to be on the structure of the tribal system in ancient Africa. He's talked quite a bit about how what he learned there fits the situation today. He pointed out that. After a few minutes I felt the head of his cock swell up and right after it did he shot his load into my mouth. I swallowed as much as I could but some dripped out of my mouth. He pulled his cock out of my mouth and bent down and licked my lips and gave me a deep kiss. He stood up and laid me on the bed, with my legs hanging off the side. He pulled the front of my panties down and released my clit. He started playing with it and kissed the head of it. He looked at me and said now I will return.
