SIL bent me over kitchen bench

This happened this afternoon. Wished it had sooner.

I'm living with my daughter and son in law, his 2 kids from a previous failed relationship. They are at there Mum's a few hours away. They have another son together, who is here.
Every time his kids go to there Mum's, he turns weird, like he misses them too much as he is a caring but I feel a little too doting father at times.

It's usually around these times my daughter and him argue more. This was a particularly bad one where it became physical.
She'd gone to hot him and it ended up with his hands around her throat. This is not how he normally is but there is no excuse, she was furious and being the spiteful bitch she is, she called the cops. She had bruises while he only had red marks and a small scratch.
He was eventually charged with common assault, she wasn't charged at all.

She decided to spend the night at a friend's house with their son, I stayed completely out of it, not wishing to be involved or taking sides. They are both hot headed at times and this just was a combination of both.

He went to see their son before going to bed and he came back a bit calmer.

My room is at the back of the house on the opposite side of the house to the rest of the house and their bedroom.
I heard my grandson and decided to stay in my room, listening for raised voices but it all seemed quiet.
I needed to pee and had to go out past the kitchen where they were sitting chatting and heard her crying.
I pee'd, made coffee and stayed out of their way to let them talk and hopefully sort things out.
They ended up going for lunch and as my grandson needed a sleep, they put him in bed then their bedroom door was shut.
I didn't hear any sounds but I was not close to their room but I figured they were fucking. Nothing better than make up sex, I've always said.

About an hour later, she came to say she was staying at her friends a couple more nights and we hugged and she cried as she grabbed my grandson and left.

I've always gotten on well with Greg, he's fit and takes good care of himself and ok yes I had a bit of jealousy that my girl found such a catch.

I made another coffee and was standing in the kitchen when he came in.
"You look a little happier."

"Yeah, we had a good talk and realised we were both at fault and I just went too far, she really regrets calling the cops,"

"And I bet you just had make up sex, that always helps." I laughed. He looked at me with a grin and said, it really wasn't that good to be honest," I stupidly said,

"Well she's obviously not like her mother, I've always loved it," he gave me a look then moved towards me and grabbed my boob and kissed me.

I didn't fight him off, far from it. I kissed him and found his cock and rubbed it through his shorts, I hadn't had sex for a few months and I was not missing out here.

I had been slack and hadn't gotten out of my nighty, but I did have clean panties. He spun me around, lifted my nighty, tugged at my panties and no hesitation, pushed his cock right into my now moist fuck hole,
"Yes Greg, go on sweety take out your frustrations on me, fuck me hard and try to hurt me,"
He listened and was pounding hard into my old cunt, his cock was around 8" and so girthy, it filled my old worn out cunt so well.

I looked over my shoulder at him as he had a strong grip of my hips, leaning back and hammering into me just as I liked it. His eyes closed as he was pushing and the look on his face, I saw the anger leave him.

"Yes Greg, fuck me, use my cunt,boh god I love how big your cock is, fuck me sweetheart fuck your mother in law's cunt. Ohhhh fuuuck yes,"
I felt the build up to my orgasm, he was good and I was thrashing wildly, "don't stop darling, I'm so close, ohh yesss," then to my surprise the bastard pulls his cock out and stood back.

"NOOO, YOU CAN'T DO THAT,"
"Yes I can, it'll make you even hungrier for my cock,"

"There really is no need, I've thought about about it often, but baby, don't leave me like this. My hand went strait to my clit and I started rubbing it frantically.

He walked to the loungeroom and laid on the floor after stripping naked. I obviously followed after dropping my panties and getting out of my nighty.
He was on his back and I straddled him,
"No escaping now you shit head."

He immediately grabbed my tits and I love tit play and I'm sure he was aware of that and he was pulling, twisting and flicking my nipples and the sensation went straight to my cunt, which just made me start grinding his big fat cock.

I was loving this and I was riding, grinding, gyrating like a crazy woman, I started rubbing my clit then it started, my orgasm was staring at my toes and eventually I came to an amazing crescendo.

"OOOHHH FUUUUCK GREG,"
Then I felt him tense up and his body jerked and I felt his baby swimmers fill me, and he shot so hard it felt wonderful, and that took my orgasm to another level.

I was done, I fell to the floor, his cum trickling out my cunt and it felt refreshing.

"No wonder my daughter's so happy with you, that was just what I needed baby," I summoned up the energy to move closer and we kissed.

"I've actually wanted to do that for so long," he admitted.
"Why?"
"You just have this air about you, a slutty kind of way that attracted me to you," I blushed.

"Well perhaps we should have done this earlier, I've wondered about you as well," we both looked at each other, his green eyes not moving as he stared into mine.

"Ok well, I'd better have a shower, I've got calls to make." He got up, walked off leaving me there still glowing.
