Her Demands

These are the events as I remember them.

When we were teenagers my younger sister Cassey caught me being fucked by an older guy in our home.
I was supposed to be looking after her with our parents away, but i'd let her go out, knowing I was going to have sex with a neighbor of ours.
Before I realised she was there, she'd taken a video of me taking the guys cock up my ass, as I leaned over the arm of the sofa.

When I did see Cassey, my sister was touching herself through her dress.
She threatened to tell our parents as the guy got dressed and left our home. She then threatened to send my dad, who absolutely hates anything to do with gay sex or men, the video.

After lots of arguing and trying to get Cassey to see my point of view, my sister who was seventeen at the time said this "If you let me suck your dick, I'll delete the video".
I point blank refused at first, so she went to her room saying things like "I hope dad doesn't get too angry with you".

I was in between a rock and a hard place, and she knew it.

I had a shower thinking the whole time, would Cassey actually tell our parents. As I dried myself in my room, I got a message on my phone. It read "Come into my room. Well sort this out".

When I walked in Cassey was lying naked on her bed, her legs apart and she was playing with her pussy.
As you can probably guess, I'm bisexual. Even though I enjoy being fucked, I still prefer fucking women with my large cock. And that's what Cassey wanted, all eight and a half inches of my dick.

Seeing her pussy for the first time, just stood with a towel wrapped around me, I couldn't help but get a boner and she smiled as she saw the tent.
Telling me my cock wouldn't be her first, I let my kid sister remove the towel after sitting up, then watched her engulf my cock with her mouth.
Closing my eyes I stood at the foot of her bed and experienced one of the best blow jobs, even to this day, I've ever had.

My sister worshipped every single inch of my cock and balls, sending me close to orgasm several times before stopping.
Each time I looked down at her beautiful body, medium sized tits, long brunette hair flowing down her back to her gorgeous looking ass, it had my cock pulsing.
Then with her mouth sucking hard on my dick, it erupted and my little sister swallowed every single drop.

Stood there recovering from such a wonderful blow job, I had my eyes closed. When I heard her say "Well, it's your turn" I opened my eyes to see her holding her pussy lips apart.
My sister has a large clitoris and at that time it was engorged. Telling me to lick her, I knelt down, put my face between her legs and tentatively at first began to tongue my own sisters sweet tasting c**t.
After a minute or so, she gripped my hair, pulled my face into her sex and told me to suck on her clit.
Doing as she'd asked, it wasn't long before she arched upwards and orgasmed shaking violently. Her creamy pussy oozed her love juice and my sister had me lick it all up and swallow it. Pushing my face back into her pussy, she practically ordered me to lick her pussy and asshole, and like a compliant sex slave, I did as my younger sister wanted.

We stayed in her bedroom another hour, with Cassey and I fucking once more. She rode my cock as I played with her firm tits and when I came deep inside her a second time, Cassey pulled her legs right up as she lay on her back, then had me give her another tonguing.

That day set the tone for our relationship to this day. Every time we got a chance to, we were fucking. And that only increased when Cassey found out she couldn't have children.
It got so we'd encourage our parents to take weekend breaks away, then we'd spend hours having sex each day.

When she moved out to go to college, I'd visit my sister at her rented flat every so often and enjoy the immediate passion we both still had for each other.
Around that time I was also being fucked by my boss at work. He paid me extra each month as a 'bonus' which enabled me to travel abroad every so often.
Cassey and I would arrange our times off together and travel as siblings, booking separate rooms. But we'd always sleep together anyway.

Things slowed down between us when Cassey began dating a guy, but occasionally we'd meet up and have sex.
She'd tell me it was never the same, or better, with any of the other guys she dated. And that included her latest boyfriend.

Then just over a year ago, she turned up on my doorstep. She'd split up with her boyfriend when my sister wanted more sex from their relationship. He couldn't match her libido, so their relationship ended.

No sooner had Cassey put her bags down in my home that late afternoon, she dropped down, took out my cock and gave me a beautifully long slow blow job.
We licked, sucked and fucked the rest of that day until we fell asleep in each others arms on my bed in the dark.

I woke up the following morning with her beautiful naked body and her gorgeous ass staring at me. I got an instant erection and very slowly spooned my sister, sliding my cock up her asshole.
Her soft moans soon turned into moans of pleasure as she had her first orgasm.
Once I knew she was fully awake, I moved us around so I was kneeling behind Cassey and then I fucked her ass like there was no tomorrow.

And a year on from her moving in, most mornings I wake up to her stunning nakedness and fuck whichever hole, mouth, pussy or ass, my cock wants that day.

Cassey knows my boss is still fucking me, and occasionally another older guy I met at a company seminar day. We meet at a motel near to his martial home for gay sex, but my sister also knows she's the perfect woman for me.

Our parents know about us too. My dad doesn't like it one bit, but has kind of accepted our love as real. Mom doesn't bat an eyelid when she visits. It's as though she always knew we were having sex. As do a couple of very close friends. But to everyone else, we're just a young man and wife living our lives. And long may it continue.

There are many many more 'adventures' and life stories I could put down here about me and Cassey. This is a very brief slice of our lives together. We're not harming anyone and we're careful not to offend people too. So we'll live our lives together for as long as we both want to enjoy our family love.
