As I entered my house I explained in précis form, the events of the last two days. I told her I'd explain more fully when we next met. Proving hersel... to be the friend I knew her to be, she offered to cancel a trip to the theatre that night to come around and keep me company. I explained that I was feeling a lot better than expected and there was no need to cancel her night out. She was dubious about my answer but agreed that she and Sam would be round tomorrow evening.The next hour was spent. The ‘Oh fuck yes’ you heard her moan was as he entered her arse after spitting on it. The slurping you can hear is as she is now sucking my cock...and Gary just unloaded over her face again. Her tits are swinging like fuck!Mate she is fucking gonna be screwed daft here.’With that he hung up just as I spunked another load all over the floor.The last pic I got was of her in this position from the side. Taking a load over her face with her being double fucked. The old guy behind her looked. Could you do that, Henry? For me and for Ellen?"For a while, no answer came from him and Josie knew that he had to think about what she had asked of him. When he finally answered, his voice was carefully neutral. She felt Ellen tense up slightly."Josie, I could do that, no question. Ellen is like my sister in many ways and I care for her. The problem is, in certain ways, she's more than a sister, at least more than sisters should be. You know how I feel for you, Josie. Still, lying with Ellen. .." I stammered."Well then, in that case I want you to come and sit on this chair in front of me." She said.I did as I was told, but tried to put my cock back into my shorts but she slapped my wrists and told me to leave it as it was."Now then..." She started, "I want you to show me exactly what you were doing, but this time from an angle where I can see you, and I don't want your hands slipping anywhere else they shouldn't!"I paused, shocked. Had my mother-in-law really just instructed me to.
