Dad explained that mom liked to wear it and shove it in his ass. He bent over and placed the head of it against his hole and kinda demonstrated how it...worked without actually shoving it in. I was a little freaked out to tell the truth but really starting to get horny and since I was already naked, dad noticed it and reached over and took my cock in his hand and kinda stroked it a bit and told me that they would love to teach me a few things tonight.A couple hours passed and I was out by the.
