Have you ever seen a horse fuck a human woman. My family owns horses and we have a stable. One night a bunch of us we’re being entertained by this women getting fucked by a horse. It was an awesome thing to see. I was was watching the animals dick go in and out. A man was holding him back so he didn’t injure the woman. I didn’t expect to see my mother Gwedaline suddenly appear among the crowd. She was half in the bag a shocked look on her inebriated face.

She’d been pretty much soused since my father’s funeral a couple weeks before. She was not handling my father’s death well. So I put my plan into action.

I didn’t stay for the finale I got my mother out of there and into my car. I stopped at a motel and took her inside registering as man and wife. I took her up to the room carried her over the threshold and kissed her deeply and lovingly then I fucked the living shit out of her.

In the morning I was in the shower when she came in to the bathroom in a white hotel robe. It was open she was naked her big saggy tits were hanging out making my cock jump.

Edward did you fuck me last night she asked and was there a horse?

Yes to both questions there was a horse and I brought you here to fuck.

You know I am not that old you could have used a rubber.

Why would I do that I want to get you pregnant.

I am your mom for one thing and did you say you wanted to get me pregnant?

Yep I said showing her my renewed hardon. Why don’t you climb in so we can make sure.

I ... I she started unsure of what to say so I pulled her into shower robe and all and gave her the deepest most loving kiss in recent human memory. She melted and I stuck my cock in my new wife’s home and fucked her some more.

Later as she was getting back in the dress from the night before. I guess we are married she absently said. Yep. What do we do about the servants?

Pension them off and hire new. Preferably from outside the state.

Then what?

We start making babies.

But I am your mom?

You just said you were my wife.

I know it’s weird part of me wants to run, part of me is ashamed and part of me wants to be kept barefoot and pregnant by you. I just oh god you are going to fuck me again aren’t you and I just did my hair and makeup?

I smiled and I did.

A month later I came home to find my mom sitting at the table. We had pensioned off the servants except Martha McGee. She told my mom I know what’s going on and I will keep my mouth shut.

Mom wanting to make sure sent me to fuck Martha. Martha was hesitant at first but then she let me between her legs because I told her mom said after this she was family. I fucked her and Mom every chance I got. Mom told her she didn’t have to be head maid anymore she could just be a woman of leisure. She was having none of it.

So I sat down next to Mom and said how is it going my love. The new servants thought we were husband and wife.

Oh just fine my love she said sliding a pee stick my way. It said pregnant.

Well that is good news.

Then she slid another one across to me. It also said pregnant. You did two tests I asked confused?

It’s not mine.

She’s not.

She is and not too happy about it but I think that’s more of a front. I think she is ecstatic So go see your other wife and have a chat or a fuck you know where I’ll be.

I knocked on Martha’s door. She wasn’t in the servants area anymore she was in the main area of the house. Come in.

I opened the door and closed it.

She told you did she?

She said you are upset about it.

I was because of the shock of the thing but what’s done is done and I’ll carry this babe and any others you plant.

So you are not opposed to having more kids.

Do I have a choice. I can’t say no to that cock of yours and I can’t use birth control.

I could stop loving you so much.

She laughed you can no more keep that cock out of me then I can keep my legs closed around you. No this won’t be an only child and I suspect neither will your wife’s.

I belong to you. So come give us a proper fuck.

The months wore on and their bellies swelled. Martha finally agreed not to work anymore which gave us more time for sex. She did keep an eye on things though. The babies came and the house was full again. The maids running to see to the needs of their two masters and their offspring. Eventually I got back in the saddle and they both got pregnant again.

I was loving being a kept man. It was great. But then things changed.

One fine spring day I went for a ride and when I returned there was an unfamiliar car in the drive.

Turned out it was my cousin and her mom my aunt. They came to see the babies.

They were upstairs in the nursery when I walked in. There is the guilty party my Aunt Sarah said on seeing me then she gave me a big hug. I think I felt her hard nipples dig into my chest.

Good job she told me like I had made the babies and not just help fertilize the eggs.

Then my cousin Allie all of eighteen smelling like hot pussy hugged me as well and whispered in my ear I want one too.

I went over and kissed my mother/wife and I then asked where is Martha?

Downstairs supervising. She will not stop but you know she is is going to have to. We are both pregnant again at the same time but she is already showing.

You know what that means my aunt said.

Multiples my mom answered twins or more.
