My wife and I had been working with the 4 year old boy and getting him comfortable in a family setting when we got a call asking if we could take on a 4 year old girl. We explained that we didn't have a separate room and we were told, "It's okay... if they are under 5 they can share a room."

Although we were concerned about the extra work, it did also mean a little bit of extra income, so we reluctantly said "Yes."

When they dropped this little girl off, she came with a similar story to our foster son. She had been sexually abused, had difficulty communicating, and was still in diapers.

We spent the next few weeks getting them acquainted and showing them what it was like to be in a "real family."

Then my wife needed to attend a foster parent training course which was going to last all Saturday. We took turns since we needed one parent to stay with the kids, so I had the duty this time.

A few hours into it, I went to change Jacobs diaper and decided I should change Ashlie's as well. I got them in there, laid them both on the bed, and stripped off each of their diapers. I grabbed a baby wipe and wiped both of them down and both of them immediately grabbed hold of their respective "privates."

As I watched this little scene I started to get a bit excited -- and then I realized that Jacob had another little hard on. Knowing that Ash would see, I spread his little legs and started licking his balls and cock. I didn't want to put his dick in my mouth because I didn't want her to think I was biting him and because I was hoping she would be doing this as well.

After a minute I heard her say "I do it?" I said, "Sure, baby... it's fun. But be gentle, okay?" Jacob laid there and watch this little naked girl licking his dick. I about came in my pants.

After a few minutes Jacob giggled and said "That's enough." and she stood back up.

I then laid her back onto the bed and started licking her little pussy. I licked her little clit with the tip of my tongue and pressed my tongue into her tight pussy hold a few times, fucking her with the tip of my tong. As Jacob watched, I said, "Watch Jake" -- and I licked her little clit. "That tickles, Mike", she said.

I said, "Jake, do you want to try this?" But he wasn't willing.

And as I looked at his little 2 inch boner I had a very interesting thought. I laid him back on the bed with his little hard on sticking up, I put a little Desitin baby rash cream on her little pussy, and I lifted her over his dick. I slowly slipped her down onto his little dick and then gravity helped me slide his dick into her.

I lifted her slightly and let her slide back down. I did that again... and again... and again... and then she started lifting herself and going back down. There in front of me were two 4 year olds fucking.

I pulled my cock out and started jacking off.

Soon I felt that familiar tingling in my balls and as I started to spurt my cum out all over these little children fucking on my bed, I heard a voice behind me. It was my wife saying, "That's the hottest fucking thing I have ever seen in my life!"

At first I thought I had misheard her and then I thought to myself that she was mocking me -- and then I realized that she had one hand on a breast and the other inside the waistband of her sweats.

"The meeting got cut short because the trainer was sick... but I'm glad I got to come home early." she said as she fingered herself and watched the three of us.

I knew then that I couldn't love my wife any more than I did at this very moment. I wondered what adventures we would get to have together.
