My cum-slut wife part 2

When I found out my wife’s sister, Leesa and her boyfriend Jackson were coming for dinner, I really wasn’t sure what to expect.
I’d come to learn that being married to my cum-slut wife, Mandy meant all you could ever do is expect the unexpected!
Leesa is a couple of years older than Mandy, and you can see the family resemblance. But whilst my wife Mandy has the figure of a model, Leesa is a little heavier, and has much bigger breasts. Her boyfriend Jackson was a nice guy.. But he was a big lad. More than a little overweight, and I’d often heard Mandy and Leesa discussing Jackson’s lack of interest in sex, and the problems of screwing a heavy-set guy. The fact that Leesa said the guy only had a little dick didn’t help matters!
They were a good couple, but poor Leesa was climbing the walls with sexual frustration! She could rarely coax a fuck out of Jackson, and when she did get him in the mood, his little cock and big physique made the event disappointing.
An hour before they were due to arrive, Mandy sent me to the shops for wine. When I came back, she was waiting for me. She was sitting on the lounge, watching a porno movie. Her little skirt was hiked up around her waist, her legs spread wide and her favourite vibrator was buried up to the hilt inside her juicy pussy.
“Come and lick me!” she said urgently. I left the bottles of wine on the TV cabinet and obediently knelt before my wife’s open legs. “Hurry!” she insisted. The vibrator slid from her cunt with a gush of thick creamy cum, and she wrapped her hand around the back of my head to pull my mouth into her.
I hesitated. “Mandy, they’ll be here in half an hour! Can’t we..”
“Now, Pete!” Mandy insisted. I knew better than to argue. Mandy was horny 24/7. It was one of the things I loved about her. It was also one of the things that had kept me from looking at another women..
I slid my tongue between the folds of my wife’s cunt and began lapping up her juices. This set Mandy off.
One of the things I love most is dirty talk. Mandy was an expert!
“That’s it, baby!” she growled, arching her back and pulling my face harder against her. “Shove that fucking tongue inside your mummy’s wet cunt! Fuck me with your face! Yeah, my big boy..” she was close to another orgasm. Her breathing was coming in short throaty pants. “Fuck mummmmmmyyyy!”
Mandy’s cunt gushed another flood of warm milky cum and I stayed between her gaping legs until I had licked and swallowed every drop of her cream. By the time I was done, Mandy had calmed herself. I looked up to see my wife sucking the last traces of her juice of the end of the vibrator, and she was smiling.
“Did that make my boy’s cock hard?” Mandy purred. “Does my big boy like licking his nasty mummy’s pussy?”
“Yes,” I said simply.
“Yes, what?”
“Yes, mummy,” I admitted, joining her in this fantasy. “I love licking your pussy.”
“Call me mummy!”
I stood up and my wife grabbed at the bulge in my jeans. Without a word she began unbuckling and unzipping my pants.
Mandy is a cum-addict. I have no doubt that all the while she was diddling herself and I was licking her pussy, she had been fantasising about swallowing my cum. She regularly milks my cock three times a day. Sometimes, when she is particularly horny, she insists on a fourth shot. Sometimes, when things are hectic, or her teenage daughter Rebecca is around the house, twice a day has to be enough to keep her going.
Now she was stroking my cock with short, rapid movements, bringing me to full hardness. Then she reached between the lounge cushions and produced a condom.
“Pull your cock for mummy,” she encouraged. “I love watching you stroke that big piece of meat.”
I did as she said. Mandy sat back for a moment, watching me pull myself, as she unwrapped the condom.
Then she leaned forward, licked the head of my cock and rolled the condom on with practiced ease.
I stood still. Mandy put her hands on my butt cheeks and pulled me into her open mouth.
I really was hard. And I was aroused. I hadn’t been milked since that morning. My cock was used to plenty of attention, and I was ready to give her my cum.
Mandy sucked me with the efficiency of a machine. She used her tongue to tease my shaft and balls, and she took me deep down the back of her throat until her nose was nestled against my groin. It was just like being deep inside her pussy, but she had all the control.
When I was close to cumming I put one hand on Mandy’s shoulder and the other around the back of her head. I grabbed a fistful of her long black hair, and Mandy knew the signs well enough to relax.
