Loving Family

We're I her bedroom and I've just been licking and tonguing her pussy and clit.
She's just orgasmed for the second time, when she suggests we sixty nine.
My cock is about to explode after only a few minutes of her sucking on me when her bedroom door opens.
We both jump up and use the duvet to cover our nakedness.
Looking down at us is our mom. She tells us we shouldn't be fucking as we're siblings, but then who's she to say anything with her countless lovers.
To prove a point, I get my sister to kneel in front of me and slide my cock into her pussy from behind as mom watches.
I see the gleam in her eye as she tells us again its wrong. But then it's the same gleam in her eye she's had since I was seventeen, and she visited my bedroom.
I fucked my mom that night after her teaching me all about cunnilingus and how to pleasure a woman.
Telling our mom I'll come to her room afterwards, she knows she hasn't anything more to say, so I continued to fuck her daughter.
My sister climaxed again before I came deep inside her c**t. A pussy I'd been fucking for only a few weeks.
Moms waiting naked on her bed and she's playing with her clit. Straight away I get between her legs and begin kissing, licking and tonguing her vagina and clit.
She moans a lot and after only a short time has her first orgasm. One of many over the next hour.
When I walked out to have a shower, my balls are drained and both women in our household have my cum in them.
It's now eighteen months on and my older sister now lives with her boyfriend. However mom and me are still enjoying sex most nights.
Every now and then my sister visits and we always fuck. She tells me her boyfriend has a bigger cock, but he's nowhere near as good at going down on her.
It's funny as much as I've now fucked my mom and sister, they won't let me fuck them together, even though I suspect they've had sex.
Happy guy who loves his family.
