Take viagra for case and stepmother helps him with erection

last night I drank a lot and this morning I had a terrible headache. I was desperate because of the pain, so I went into the kitchen to take a pill. My stepmother told me that the pill was on the table, so I took it without thinking twice. But I took the pill wrong. I took for mistake the Viagra. So now I had an erection terrible. My stepmother was sorry for me, so he wanted to help me. He removed his pants and told me to use her vagina. I was behind her and I fucked. Then gave me a blowjob that I ejaculated. But I was still excited. Then I fucked again.
