The Night I Spankee and Hatefucked My SIL [MF]

I am not necessarily proud of what I am about to write. On the other hand, I am not exactly ashamed either. It was satisfying, and hot, and brought my wife and I even closer than we already were. So, enjoy.

My sister-in-law, then in her early 20s and ten years younger than we were, was the baby of her family, and a total bitch. She was never told “No” growing up, never disciplined, never suffered a moment of deferred gratification. And it showed.

Consequently; she walked around ordering everyone in her life around, never expressing gratitude for the generosity and love she was shown, and to be honest, it drove me crazy.

I had come from a family where everyone was taught to be humble and grateful and disciplined, and it upset me to watch her run roughshod over everyone around her — especially my wife.

My wife, as the oldest child, had that caretaker mentality and bent over backward to show her sister nothing but exceptional love and hospitality whenever we were together.

That usually earned my wife only more demands and passive-aggressive insults. Those hurt my wife, but she usually swallowed thst hurt and insisted I do the same on her behalf.

This night was no diffeeent. My SIL, staying with us a few days while visiting with friends in the city where we lived, dismissed and insulted my wife the entire time, especially during a really nice dinner my wife had made for her.

My wife and I were in the kitchen, cleaning up from dinner. I was quietly fuming while we cleaned, until my wife said something about how she should stand up to her sister. I growled something in response like, “What she needs is to be dragged upstairs and have her ass turned a deep shade of red.”

My wife suddenly stopped what she was doing and put her dish towel on the counter.

“Would you?” she asked quietly, without turning around.

I couldn’t believe what had just come out of her mouth.

“What?” I asked in response, not quite believing what I thought I heard. She turned to me, buried her head in my chest, and said:

“Would you…take her up to the guest room and punish her for being such a bitch. I have tried as tried to be patient, and understanding, but I can’t take it anymore. My parents have refused to discipline her for her entire life.”

Then she pulled back and looked into my eyes, with a smirk and something resembling a slight bit of arousal. “And I know from personal experience those big hands of yours can deliver a powerful sting when they need to.”

“Do you mean it — you want me to ?” I asked.

She just looked at me and said, “Yes.”

I didn’t need to hear it again. It was something I had wanted to do for years. Part of me was eager to do it, and a bigger part of me believed it was necessary and that her sister deserved it in spades.

I turned and walked out of the kitchen into the living room. My SIL was lounging in the couch, in a t shirt and one of those pairs of shorts made of sweatpants material with the waist that folded/ rolled down.

She made some dismissive comment about our cleaning f efforts. If I harbored any doubt about what I intended to do, the contempt in her voice erased it instantly.

I grabbed her by the arm and dragged her to her feet, and began moving her to the stairs.

She spluttered “What? What do you think you are doing? Let go of me!”

I told her to shut her mouth, and kept us moving. We got up the stairs. The guest room was just a little further up on the left.

I pushed her into the room , then grabbed her and dragged her across my lap as I sat down on the edge of the bed.

As I grabbed that little roll of fabric and ripped her shorts and panties down to her ankles. “What the hell are you…” she blurted out before the first hard smack landed on her bare ass.

“Ow, holy fuck what are you…” she got out before my right hand landed again.

She howlef as I laid into her ass and began to explain — admittedly more yelling than explaining.

“I am sick and fucking tired of hearing you insult and degrade and disrespect my wife — and for that matter, everyone around you. I doing what you father should have done YRARS ago.”

As I spanked her hard over and over, I said, “From now on, if you come into our house, and disrespect us, ESPECIALLY you sister, my wife, I will wear your ass OUT!”

She began to cry out in spurts, and as her ass turns a deep shade of pink all over, those spurts turned into continuous crying .

“I’m sorrrrrryyyyyy,” she wailed. “I won’t do it again, pleaaasssseee.”

I kept up the pace and told her, “This is going to keep going until I believe you will think twice about treating g you sister like shit. And you can be damn sure that if you so much as look at her crosswise, you will end up right back here having your butt beat until you are begging for it to stop. Do you understand me!?!”

“Yesssss, please, I won’t do it againnnnnn!”

I stopped and let her cries diminish to sniffles and the occasional plaintive moan.

“That really hurt,” she said to me.

“That’s kind of the point,” I replied.

She climbed off my lap, still naked from the waist down, and gingerly curls her feet under her ass so it didn’t hit the bed.

“No one has ever spanked me before,” she said in a small voice. “It really hurt, but it as also kinda hot.”

I was still worked up, and when I looke up, there was desire in her face.

I stood up, spun her around so her red ass was bent over the bed, and without a word, looses my jeans, freed my cock, and plunged it roughly into her. She cried out “oh, fuck!” as I buried myself in her. Over and over and over againI thrust myself into her pussy, caring not to use her as a vessel to pour my frustration and energy into. I occasionally smacked her ass hard as I did, eliciting more howls of pain in between moans and squeals of pleasure.

Sensing I was about to explode, I pulled out and erupts all over her back.

Done, I growled at her and said, when you come downstairs, you bettee sweetness and light.”

She nodded meekly.

I went downstairs but didn’t see my wife anywhere.

I walked into our bedroom to find her standing in the middle of the room wearing nothing but a t-shirt and panties. Her nipples, rock hard, were jutting through the fabric.

“You head all of that, I presume?”

She smiled and walked to me, leaning into me.”

“Mmmmm-hmmmm,” she said.

“You gave her exactly what she deserved. But I am afraid that knowing what you were capable of, it was very bad of me to send her to that destiny. . “

“I think I need to be punished. Especially that last part. A few times.”
