Chapter 1

I was still close to my in-laws. 

My wife and I had separated about six months and yes I was still angry at her but her family had always been so good to me.

Driving home from work, I passed near their house so decided to call in. The sliding door was open so I knocked and entered as I always have. There was no sign of either of them, but it was strange for the door to be open if nobody was home. They live in a single level house. So I walked down the hallway and heard a little noise.

As I got near their room, the door was open, and there she was. My mother in law naked on her knees sucking on my father in law. Her hands were on his ass and he had one hand stroking her hair as she slurped on his six-inch cock.

“Oh my god, I’m so sorry!” I blurted

They both jumped in shock. Diane’s eyes were wide and she quickly tried to cover her nakedness. Dave, I could tell, was wanting to do the same but he was too far gone and started shooting thick cum towards Diane.

I turned to leave, embarrassed but Diane sped after me.

“John, please let us explain!” she called

“There’s nothing to explain Diane, this is your house, I just walked in and. Well, I’m sorry, I had no right to,” I replied

Dave came out of the bedroom, with a towel held around his waist

“Sorry, John, I just lost control on seeing you watch us. Honestly, we’ve never done anything like that in front of anyone and at our age it’s...  Well, it’s harder to control yourself, I’m sorry.”

I looked at Diane. “It’s not my place to say and this might seem strange but I'm going to say it anyway, that was perhaps the hottest thing I’ve ever seen!”

They both looked at me. “Really?” Dave asked

“Really!” I answered

“And at least you got to orgasm!” Diane joked to dave.

We all laughed and relaxed a little. “I guess I should shower,” Said Diane, and then she left towards the bathroom.

Dave looked at me. “Did you really like it?” He asked

I looked at him and said “Yes very much. Diane has still got it then?” I laughed

“I can’t give her as much as she wants these days, John. She still wants it a few times a week and I’m lucky to get it up more than twice,” he answered

“Hey, that’s more than I’m getting these days,” I quipped back.

“Listen, why don’t you help us out then?” He asked cautiously. I was shocked but loved the idea.

“Are you suggesting what I think you’re suggesting?” I asked.

“Diane wants sex, I want her to have sex, you want sex but aren’t getting any, so why not?” Dave shrugged his shoulders but held my gaze.

“Erm, I dunno Save, it’s a fucking hot fantasy but… Well, in real life? That’s different,” I said

We stood for a few moments talking about it. I knew it was a crazy idea but I was standing there feeling horny as hell, talking with my father in law, having just recently watched him cum all over my mother in law.

“Wow, it would be fun though!” Came Diane’s voice. She was stood at the bathroom doorway now wet, with a white towel wrapped around her. I could see her erect nipples pushing at the fabric and could feel the blood rushing to my loins.

“Looks like you both like the idea!” As she looked from cock to cock. We were both on the up!

“Whoa, guys I need to think about this! Give me a night to sleep on it,” I said

“Ok,” they agreed. “But we really really hope you’ll perhaps pass this way home tomorrow too !” Said Diane.

Chapter 2

I barely slept that night. The thoughts in my head were almost surreal. Had what happened really happened? I was so worked up that the next morning I took a sick day off work.

Around 10 am I received a text from Diane. My heart fluttered and I opened it to see.

"Hey, I hope what happened yesterday hasn't changed your thoughts or view of us. We both love you like a son and didn't want to upset you in any way xx."

I messaged her straight back. "Hiya, nothing could stop me loving you guys, you've always been so good to me. If I am honest, I loved seeing what I did and want more but is that a good idea? I don't want to jeopardise our relationship. I look at you both as parent figures."

Just as quickly she responded, "Well, mummy and daddy want you to join us very much!"

I replied, "Oh my God, Diane, you are unbelievable lol. But I like it! I'm really nervous but horny right now, gonna take a cold shower."

It went quiet for a minute. Then another message. "Are you off work? Want to call around. Dave's out but I just messaged him and he said it's fine if you want to call!"

Am I really going to do this? I thought. Oh my god, I am! I showered and changed, jumped in the car and drove the fourteen miles to my in-laws' house. I opened the door and walked in, my heart was racing both with fear and excitement.

"Hi John, you didn't text back so I wasn't sure if you were going to come or not. Tea?" She asked.

As she turned to make tea I looked at her in a way I never had before. Her body was remarkable for a woman in her sixties. She had long dark hair and a trim figure. Her breasts weren't that big but still looked firm. Although I'd seen her naked the day before, it was all a blur. I couldn't really remember what her naked body looked like. But her dressed body had me horny as hell.

She turned and caught me staring at her ass. "You checking me out?" She asked

"Yes," I replied. "I can't believe I am but yes I am checking you out! And very nice it is too!"

Weirdly we sat and drank our tea talking about everyday stuff with the odd flirt and innuendo thrown in.

"Let's go in the lounge, it's warmer in there," She said.

It was mid-January, so cold outside. "Yeh, I can see you're a bit nippy!" I laughed as I noticed her erect nipples poking at her jumper.

She actually blushed and covered them. I laughed and said, "Don't cover them. I like them, they're beautiful "

"Sooooo what happens now? I know we kind of initiated this but I've never been with another man in forty years," She said

"The only woman I've been with in sixteen years is your daughter!! So I'm no expert either." I laughed but I moved close to her stroked a thumb over one of her nipples.

A gasp escaped her lips, her daughter had the same sensitive nipples and I knew exactly how to tease her.

I then rolled gently the nipple between my finger and thumb. And moved my mouth to hers. We kissed and she had a beautiful soft mouth, our tongues flicked at each other as we became more passionate. Our eyes were locked on each other.

We moved to the sofa, I lifted her jumper to reveal a sexy sheer bra. "Fuck that's sexy!" I said as I moved my mouth down and nibbled her nipples through her bra.

"Mmmm that feels so nice. I'm so turned on!" She whispered.

"Oh, Diane, I feel so bad, I want to be very naughty with you!" I said.

"Oh my god, John, do anything you want with me. Use mummy in law as you want. I'll do anything you ask, I want to try everything," she whispered

My cock had never been so hard. I unzipped my jeans and pulled it out.

I love having a big cock, my ex-wife always told me it was the biggest she'd had. But in honesty apart from her, I was fairly inexperienced.

"Wow! John that's amazing!" Was all she said.

"Get your son in laws hard dick in your mouth, now!" I instructed her.

She looked at me a little in surprise, but smiled coyly and said, "I've always wanted to be dominated a little. I loved those Fifty Shades Of Grey books!"

She wasted no time she slipped to the floor on her knees. I pulled off my shoes and jeans and pants she remained kneeling in front of me.

She licked my balls and up my dick, teasing the tip. Her eyes locked on mine.

"I love it, it's beautiful!" She said as she kissed and licked it then sucked it deep.

"Oh fuck, Diane, that's so nice, suck it deep," I said back. "Let me hear my prim and proper mum in law talk like a slut as she sucks my hard cock!" I added.

"Yeh?" She asked and I nodded in response.

"Mmmm your big hard cock is the biggest I've ever had, baby, it will fill me every way," She moaned as she sucked on my full balls.
Her hands went to my arse, much as I'd seen her sucking Dave the day before.

I pushed my hard cock down and rubbed it over her face. She smiled and caught it swiftly in her warm mouth. I stood there in absolute heaven watching her head begin to bob on my erection. Her eyes occasionally glanced at mine with total glee.
