It has been almost a month now since the first day I fucked my mum-in-law. The thrill of fucking her in her house just got stronger each day. I have been fucking her almost every weekday at every opportunity I got. My Saturdays and Sundays has to be reserved for fucking her daughter. Most of the time it was at her house when the small dick father-in-law of mine is not at home.

By the way, my mother-in-law's name is Zima and thanks to me, she is now a real slut of a mother-in-law. My name is Mike.

There was one time when she called me at about 11 in the morning asking me to come. She said she need me to fuck her now. "I think it is time you give your mum-in-law here a good fuck in the ass." I was in ecstasy. Here I was thinking of fucking her in the ass. It was like she knows what I want. 

"But be gentle, son. My ass has never been fucked before. You father-in-law just couldn't do it". I was going wild! I am going to anal fuck my mum-in-law!

I was on my way to see a client then. But the thought of fucking her virgin ass today was just too good to miss.

As I made my way to her apartment door, I rang the doorbell. I was shocked when my father-in-law opened the door. Surprised to see me, I told him I was around the neighbourhood and dropped by because I needed to use the bathroom.

Zima was sitting at the sofa and just smiled at me. Asking how was his business trip, my father-in-law, Zack said he had to cut short his trip and return a day earlier. He had arrived just five minutes earlier. I excused myself and went to the bathroom. It was a close call. I could have been fucking my slut mother-in-law when he came back!

As I got to the living room, Zack was alone there. Zima was in the kitchen.

Zima came back from the kitchen with a glass of cold lemonade.

"Is that all you're going tp give your son-in-law? It's not everyday that he wants to drop by and see you?" Zack asked

Zima looked at me with a smile and said " Why don't you wait for a while, Mike and I will make you a some pasta?

I just looked at her and said " Sure, mum. I would love that very much."

Zima went back to the kitchen .At the kitchen door, she turned around, looked at me and squeezed her breast. My father-in-law did not see that as he was standing behind her.

Zack excused himself and went to the room to take a shower.Knowing we only have a short time, I went to the kitchen. There she was holding a plate of pasta she has prepared earlier at the table.

"Are you going to eat the pasta or let me eat your prick,Mike? That old man is going come back very soon." Zima said

"You are going to get fucked, mum"

I grabbed her and kissed her hard in the mouth. Pulling down my zipper I told her " Get down there and suck my dick, slut." She knelt down and pulled out my dick and began sucking it hard. She grabbed my ass and squeezed them at the same time. She was sucking so hard that I can feel my balls about to explode. After some hard sucking, I grabbed her hair and pulled her up.

"You are a real slut, mum. I want to suck your breasts." I pulled up her T-shirt and began sucking hard on both her breasts. As she moaned hard with me sucking her breasts, I pulled down her skirt to her thigh, just enough to expose her ass and her now clean shaven cunt. As I expected, she was not wearing any panties.

Grabbing both her ass cheeks and still sucking her breasts, I moved my right hand to her cunt and pushed my finger into her. She was moaning "Fuck me now, son, before he comes out"

I pushed her to the kitchen table and pulled her skirt all the way down. Spreading her ass, I pushed my dick all the way in her cunt with one very hard push.

" Oooh yesss, fuck me hard, MIke. Make me cum again,son."

" You are a real slut, mum. I am going to fuck you hard, mum." Fucking her faster and harder, I could not hold it anymore. "I am going to cum now, mum"

" Ooohhh, yesss.....let me have it in my mouth,Mike" I pulled out my dick and held it tight. Zima got on the floor and took my dick into her mouth. With a few more sucking, I unloaded my juice into her mouth. She took it all in her and licked every cum I had on my prick. Still panting, she got up and pulled up her skirt.

I quickly pushed my soft prick into my boxers and pulled up my fly. I was about to grabbed her ass again when we heard the bathroom door open.

Out came my father-in-law and asked " You had your lunch, Mike?"

" Oh yes, Dad. The pasta was great." I looked at my mother-in-law and said " Mum is one hell of a cook, dad. She can make me hungry any time".

Zima looked at me and smiled " You can come here at anytime and I will cook you something nice. I only have one son-in-law, you know."

"Thanks, mum. I have to get back to the office now. See you, Dad"

I went to where Zima was standing and gave her a kiss on the cheek. I gave her ass a squeeze and was about to leave when Zima said " Mike, can you give me a lift to the bank on the way, Since your dad just got back, he must be tired"

" Yeah, Mike. You don't mind giving your mum-in-law here a ride do you?" Zack asked.

" Not at all, Dad. For mum, I will give her a ride anytime" I said looking at Zima.

Zima had a quick shower and changed into something simple with nothing inside. She kissed Zack goodbye and told him to rest and she might go to the mall after her errand.

As we got in the car, Zima said " Now Mike, you be a good boy and take your dear mum-in-law here to a motel. I am very sure you want to have my virgin ass fucked, don't you?"

I looked at her and smiled " Mum, you are the best. Your ass is mine"

We both laughed and headed out of town to check into a motel. My mother-in-law is about to get her ass fucked for the first time.
