I whirl around to see that it was my wife. She slowly gets undressed and we both get into bed together. Before we could even start my daughter barges in and gasps with surprise at the sight she is seeing. Then her brother Matthew comes in looking for us and is just as dumbfounded as his little sister. There was a few moments of awkward silence as our children just stared at us underneath the covers. Finally Maggie broke the silence and asked "Daddy what are you doing to mommy?". We explained to them that we were making love and had to explain to them how it worked. Maggie piped up again and asked "What does a penis look like?". Samantha and I looked at each other for a moment and realized that we might as well teach them everything. I looked at Maggie and asked if she wanted to see what Matthew's penis looked like. I then asked Matthew if he wanted to see what Maggie's vagina looked like. They both were very curious and wanted to know. Samantha then instructed Maggie to take off all of her clothes. Matthew watched in amazement at his sisters naked body. He felt his penis grow in his pants which became very obvious. Maggie then asked "Daddy what happened to Matthew's penis?". "Why is it so big?". I explained that men's penises get bigger when they are excited. I then instructed Matthew to remove his clothing and soon enough all four of us were naked in our bedroom. I then removed the covers so that the kids could see better and instructed them to come over to the bed. They watched in amazement as my penis sank and disappeared into their mother's vagina. I instructed Matthew to do the same and my wife and I watched as Matthew sunk his penis into his little sister's hot tight pussy. I fucked Samantha faster and harder until I felt her contracting around my penis. At that moment I reached my orgasm and filled my wife's pussy with my hot semen. Not long after the same thing happened to our children Matthew and Maggie. Samantha then told me she needed to use the restroom. All of a sudden I felt a hot sensation around my penis. I realized she had no intentions of using the toilet and has pissed all over my penis. Samantha then asked Maggie if she had to pee. Maggie replied "Yes mommy I have to pee very badly.". Samantha then told Maggie to release her pee. Maggie tried to concentrate but the pee wouldn't come out. Samantha told Maggie to just imagine that she is on the toilet. That was all it took and Maggie was peeing all over his brothers cock. Samantha then asked me and Matthew if we needed to pee. I filled Samantha with my hot piss and Matthew filled his little sister Maggie with his hot piss. I then had a erection again and began to once again fuck my wife until we both had our orgasms.
