It was a theme night. All the previous sex-acts had involved some degree of incest. The Colonel thought that, as Kim and I were related, it would be a... appropriate end to the evening. He could have been joking but I didn't think so."Why? Colonel?" I asked. "I was told you and Kim were old friends. Why the sudden change?" Yes, why are you doing this, Rob?" Kim asked. Her voice was surprisingly calm and level."I rike praying with tits!," Rob replied, deliberately misunderstanding Kim's question.. He turned her around and pulled her closer so that he could take her breasts into his mouth.

"Don't you worry my darling, I am going to do a lot. And you should do mine” I felt awkward keeping his tool in my mouth. I said “Sir,no i cant do it.” he said “okay then. If you dont,then i will not do to you too”. He noticed me when I am enjoying his suck and caught me right there.But later he told me to kiss it. I kissed. Then he told to shake and suck. I started sucking and shaking his tool. First i was feel awkward. Slowly i started enjoying it. I was gagging because his tool was so long. He was mouth fucking me. He took it from my mouth and.
