I laid back on the bed and began my show. The wife told me to slow down and show how good it felt. It was awesome having strangers watch me and it did...’t hurt having the wife in the room encouraging me. She told me to finger my ass while rubbing. I was getting close to cum but held off as long as I could. Then finally, I exploded cum. It launched up over my head hitting the wall behind me. Several squirts landed well above my head. I was so turned on I ejaculated for a solid minute straight.. Lots of thoughts were running in my mind of what aunty will react. I went at her home rang the bell but no was there so I went directly inside and found aunty sleeping I called her. After 3 to 4 times of calling she got up and asked me what is it I asked for the key. She got up with some unease holding her head. On asking she said shes having a headache. I asked about the medicine to which she told she had gone to the doctor but still it is paining. I told her that I will take the key tell me. I felt like I had a volcano in my balls and I started to cum! I never experienced an orgasm like this – the cum just gushed out of me and I filled Dagmar up with burning hot cum and she kept on orgasm. I think she had a constant orgasm for at least 5 minutes and she was almost u*********s and her head lolled to the side. I had to have more, so even as cum still flowed from my big throbbing cock, I pulled out of her pussy and just hammered my cock into her throat – really just fucking Dagmar’s. I looked up at Grandma, she could see my confusion. "I wanted to explain what my idea was before you actually changed. I never imagined it would be so complete." She opened up the book in her lap and turned it toward me.I saw an old ink etching on yellowed parchment paper of a person holding a ball over what looked like a deceased person, the ball seemingly throwing glowing rays out from the holder's hand...I looked at the book then back to her, all the while Amber talked about her drawing..
