It's been almost forty years since the first time with my sister Maddy. Since then, we have met at the same hotel to make love about once a month.

We've been married for about thirty years, and have two kids. Both of us had great marriages until last month when Maddy's husband moved out to live with his secretary.

Maddy was devastated and asked me to go and stay for a bit. When I arrived, I was greeted by Gemma, Maddy's daughter.

As she walked to the car, with her big, beautiful smile, I thought how much she looked just like my sister, who had looked like that all those years ago. I got out of the car, and she ran over to me.

"Hi, how was the drive down?"

I hugged her and kissed her forehead. "The drive was good. Wow, you've shot up."

"Well, I am seventeen. That's what happens."

"Where's your mum? Cheeky."

"She is shopping. She should be back soon."

I grabbed my bag out of the car and followed her towards the house.

"I can't believe how much you look like your mum."

Gemma looked over her shoulder at me. "Yeah, but with a much hotter ass, what do you think?"

With that, she flicked up her school skirt and showed me her cute ass in her little dark blue school panties.

"Wow, bet you get all the boys?"

She started to giggle, "Not just the boys, Uni."

Once we were in the house, she grabbed my hand and said, "Let's go to your bedroom; it's right next to mine."

We went upstairs to my bedroom, and as we entered, Gemma jumped on the bed, showing me her panties again, but this time she never covered herself up.

"Nice room," I said, trying not to stare at her creamy white thighs and panties.

As she lay there legs apart and bent she looked up to me and said, "It's not bad, it's my brother's room, and that's your en-suite, well, I mean our en-suite, it's a Jack and Jill bathroom, so remember to lock the door when you have a shower or not."

With that, she giggled, got off the bed and left through the en-suite doorway.

About ten minutes later, my sister Maddy arrived home. So, I went down and met her at her car. We unloaded the shopping and carried it into the house.

Once the shopping was away, we hugged, and over a cup of coffee, she told me all about her husband leaving, and how hard it had been for her and the kids.

"Why don't you go and freshen up while I start on getting dinner ready?"

So I went up to my room, got naked and went into the en-suite, shut the door and turned to lock Gemma's door when I saw her in the bath, naked and masturbating.

"Sorry, didn't know you were in here."

"Don't worry about it now. You're here; you might as well stay and watch. That really turns me on. Looking at that big boy, it turns you on too."

I stood there, mouth wide open, looking at my niece naked in the bath. Legs apart, with two fingers in her smooth, young pussy.

Without thinking, I started playing with my cock while watching this beautiful young girl enjoying her pussy.

"Move closer. We need to be quick before dinner's ready."

She looked beautiful: her small, perfectly formed, milky white breasts with her little dark pink hard nipples.

Her tight stomach and sweet, young, smooth pussy, I couldn't take my eyes off her as I stroked my rock-hard cock.

She hadn't taken her eyes off my hard cock. Two fingers working in and out of her pussy, her other hand was playing with her clit.

"You look so big, that's the biggest I've seen. It looks pleased to see me."

"Yes, it is, but we shouldn't."

She stopped me and said, "Shhh, let's just enjoy the moment."

So we both carried on masturbating and watching each other play with our love toys. It wasn't long before we were both cumming, Gemma was moaning and splashing in the bath as I shot two or three ropes of cum into the bath. I watched as my baby cream floated around her now-flushed body.

As we were calming down, we heard Maddy shouting, "Dinner's ready."

Gemma said, "Quickly, get to your room. Mummy's on her way up to get us for dinner."

I rushed into my room just as Maddy knocked on the door. I wrapped a towel around me and opened the door.

As soon as Maddy saw me, she put her hand on my chest and pushed me back into the room, and kissed me with one hand around my neck and the other tugging at the towel. As the towel hit my feet, I pulled away and said, "Stop, what about Gemma?"

"We don't need her." As she grabbed my semi-hard cock.

"No, she is only next door."

"Yes, you're right. I'll save this for later when she's in bed."

She left and went to Gemma's room, and I quickly got dressed.

As we sat and ate dinner, Maddy said, "I hope you looked after your uncle, well, I was shopping."

Gemma winked at me and said, "I did my best. We didn't have long."

"She was lovely. I'm sure we will get a chance to catch up in the week."

As I was speaking, I felt Gemma's foot on my crotch. I looked up at her, and she smiled, saying, "That will be a lot of fun."

After dinner, Gemma stayed in the kitchen washing up and clearing away, and Maddy took me into the lounge where we sat on the sofa and chatted while watching TV.

It seemed like Gemma was in the kitchen for ages. But when she finally came into the lounge, she brought some coffee in for us, and as she placed them on the coffee table, she bent over right in front of me.

Her little red sports shorts pulled up tight, and half her gorgeous ass pushed out the leg holes. I must have stared because Maddy elbowed me.

As she stood up, she said, "If anyone needs me for anything, I'll be in my room."

As soon as she left the room, Maddy turned to me and said, "I saw that. Don't even think about it. I don't want you fucking her."

"I was just thinking how hot you would look in those shorts."

"You liar."

And with that, she climbed across my lap and started to kiss me.

I wrapped my arms around her as she began grinding on my crotch. Our kiss became more passionate, and our tongues were darting into each other's mouths.

I lifted her t-shirt up over her breasts to see her tits wrapped in a lace pale pink bra, and I could see her dark nipples pushing against the fabric.
She broke the kiss and, in a breathless voice, said, "Fuck me, I really need to feel you in me."

She then stood up and ripped off her jeans. As I got up, she was pulling off her pale pink knickers; the wet crotch stuck to pussy.

I quickly stripped as she knelt on the sofa and pushed her ass out at me.

I got behind her and easily slid the full length of my hard shaft into her soaking pussy. I roughly grabbed her hips and fucked her hard and as fast as I could.

She was so wet that my cock kept slipping out. She buried her face in a pillow as she became loud; her moaning was driving me crazy.

Then I felt her pussy grip my cock, and she shuddered as her juices rushed out over my balls and down our legs.

She looked back at me with her flushed face and said, "Fuck my ass, fuck it hard."

So I pulled out of her and pushed back into her tight brown hole. Once I had got my purple mushroom in my sticky wet shaft, I slid all the way in, which made my sister scream.

I stood still, letting us both get used to the feeling, but Maddy had other ideas and started riding my cock while moaning loudly.

I'd never seen her so hungry for cock. She was moving fast, slamming her ass into me. I couldn't take it for long before I came hard into her back door with a loud groan, load after load filling her full of my cream.

As I pulled out my cream gushed out of her gaping hole.

She stood up and kissed me and said, "Wow, I really needed that. Thanks, now I've got to shower and get to bed. I've an early start tomorrow."

"Night, Sis. See you tomorrow."

Then she grabbed her clothes and rushed up the stairs. I tidied up, gathered up my clothes, and went straight to my en-suite for a shower.

As I walked into the en-suite, Gemma opened her door and said, "I've been waiting ages for you and your hot cock."

"We shouldn't be doing this."

"Stop talking. I'm not telling anyone."

Then she got on her knees and took my messy semi into her mouth and began sucking me.

I was shocked that she didn't stop when she tasted her mum's pussy juices and ass on my helmet.

But she didn't, and I could feel myself growing in her mouth as she worked her magic. I rested my hands on the back of her hair and started pulling her deeper onto my now-hard cock.

Her hands gripped my ass as she got me off with her mouth. I could feel my legs starting to go weak, and then, as I shot my load down her throat, her mum knocked on her door.

I pulled out and quickly went and jumped into my bed.

In the morning I woke to a message on my phone saying I was needed back at work, so I left them a note and went back home.
