I wanted to do something dirty for my son. When my husband had went to bed i listened out for my son who has a bathroom in his bedroom. When i walked in to perv on him. I was thinking we could play some water sports, instead he was taken a shit. He looked mortified i was there. I nelt down before him and took his large cock in my hand and started strocking it for him,. I told him i didn't care and took his cock in my mouth. He got big and hard really fast and i could see he was a bit frustrated, so i told him to just do it now. He farted and lit it go. While i took him back in my mouth. He seemed to cum really fast when he was doing the toilet. It must stimulate you more or something. x
