Fiction: Slut-In-Law

“Mark, what are you doing here?”

I pushed my way through the door and grabbed Claudia’s throat. She gasped as my fingers tightened. Some of her long black hair was trapped in my fingers but that was all right. I squeezed too hard and her eyes widened. I had her attention.

I kicked the door shut behind me and pushed her against the wall. She had a delicate blouse on that I ripped open. Her bra held her massive breasts and I pulled a tit out. My fingers scratched her nipple before I twisted it.

She tried to scream her pain but she was out of air.

I let go of her throat and pulled out the other breast. Her pink nipple was already hard. I clamped her nipple with my fingers and this time she did scream. I twisted both of her nipples and she rose on the tip of her toes.

“What did I do wrong?” she asked.

“That is a better answer,” I said.

Claudia wasn’t a bad mother-in-law. She just needed to be disciplined from time to time.

I released her nipples and grabbed her by her hair. “Your little comment to Trish last week.”

I pulled her by the hair to the living room. When we got to the back of the couch, Claudia tried to pull away. I brought her face up and slapped her twice.

“Over the couch,” I growled.

She looked down shyly. For a brief flash I saw her as demure young girl instead of the forty something woman she was. It was only a moment, because she unzipped her pants without being told and pulled her pants down. My slut-in-law wasn’t wearing panties.

“Oh you knew,” I said.

Claudia looked at me with those wise green eyes of hers and bent over the couch. She braced her legs in an arch and presented her ass. The bitch was playing me, but damn, she did have a wonderful ass.

“Tell me what I did,” she said.

I took off my belt. “You told Trish that the reason she looked chubby in her swimsuit was because of all the butter she used for the mashed potatoes. Now Trish is on a diet and damn it, the mashed potatoes suck with less butter.”

Claudia clenched her very tight buttocks. “I’m sorry. I didn’t realize Trish would take it so personally.”

I hit her with my belt. Claudia hissed and arched her back. I pushed her head back down over the couch.

“You are an awful liar,” I said. She whimpered in response. There was nothing more to say.

I whipped her ass. I have never spanked my kids and I have certainly never spanked Trish. There was something about Claudia though that brought it out in me. Mercy left me. Marks appeared on her ass; horrible angry looking welts and yet I kept whipping her. When I whipped my mother-in-law, I became a different person.

At first I used to think it was because I knew of her Claudia’s sins. I knew about the ways she used to nag Trish when Trish was a teenager. I knew about how Claudia’s insistence on cleanliness had given Trish a minor bacteria phobia. I knew a hundred different secret ways that Trish resented her mother and how Trish hated herself for disliking her popular mother sometimes. In my mind, whipping Claudia was helping Trish get some sort of second hand revenge. It was karma.

“Oh fuck!” Claudia yelled as my belt went between her legs and landed on her cunt. I hit her there a few more times. The blows were barely slaps but on her sensitive sex, the pain was shocking.

I knew the truth these days. I punished Claudia because it was fucking hot. The infractions she committed were just an excuse.

The belt fell from my hands. Claudia jumped as the buckle hit the floor. She was breathing hard and swaying her ass back and forth as if she was trying to cool it off.

“Your punishment isn’t over,” I said.

My mother-in-law groaned. “My mouth?” she asked.

“No.”

“My pussy?” she begged.

“No.”

Claudia moaned.

I spread her buttocks apart. She screamed as my fingers touched her marks. I took the bottle of lube out of my pocket and applied it to my cock.

“Please, I’ll be good,” she whined.

I slipped my cock into her ass. She moaned as she took everything I had. I could feel every tremble of her body. My hands went to her black hair and pulled her head back so I could see her face in the mirror above the mantle.

She was smiling.

I took my time. We fucked for a good half an hour. I added a few more welts to her ass with my hand. I’ll say this about Claudia, for an older woman, she can take a fucking. I hope Trish had this much endurance when she is her age.

Claudia came twice. The first time I caught her fingering herself as I fucked her ass. I let her finish but then I forbade her from touching herself. The second orgasm she got from my hand. I needed to feel her ass clench in that spasm way of hers when she comes.

I came in Claudia’s ass. She hates it but then, that’s why I do it. She knew better than to complain.

“You’ll behave,” I said later. I was dressed again while Claudia was naked on the floor. She was a beautiful sweaty mess.

“Yes,” she said. I believed her. For now.

“Good,” I said.

As I went to my car, I saw another car pulling into the driveway. I waited to see who it was. I smirked a little when I saw it was Brian.

“What did she do?” I asked.

Brian slammed the door of his car and came towards me. “Claudia told Shelly that she needed to stop wearing shorts because her thighs were too big.”

“Damn, that is cold,” I said. “Well, fair warning, I just whipped her ass and fucked it.”

He nodded. “That’s okay. I was thinking about doing some breast binding and face fucking her. After talking Shelly out of not throwing away all of her shorts for half of Sunday, I’m not leaving here till I bust a nut in Claudia’s mouth.”

I got into my car. “Sounds good. Oh, tell Claudia Happy Mother’s Day. I forgot.”
