It has been a couple of weeks since Shelley's first session with Simon, and Friday was her fortnightly day off. I hadn't said anything but I wondered if she would be visiting him again. I got a text message early afternoon Saying 'I've been naughty' with a smiley face. It seemed Shelley was enjoying the game as well as the sex.

That night she told me the story. She sent a message to him to say she was coming, when she got there he was naked and grinning. She laughed and said I want a coffee first, I didn't get one last time. She made herself one while he stood in the kitchen stroking himself hard. She went into the lounge and waited while she sipped her drink, enjoying the teasing.

Feeling in control, Shelley told him to come over and eat her pussy while she finished her coffee. He dutifully went over, removed her jeans and panties and fingered her for a minute or two. He then proceeded to kiss the inside of her thighs, before probing in and out of her cunt with his tongue, and sucking her pussy lips. He kept that up for several minutes. Simon pulled away so he could finger bang her with two fingers, while sucking hard on the clitoris.

"Oh yeah that's good " Shelley moaned, and he continued until Shelley bucked up and moaned loudly as she came hard.

Simon stood up and thrust his cock as deep into Shelley's mouth as he could and held it there. Eventually he pulled out leaving her gasping, before doing it several more times. She complied with no complaints, liking the cock in the back of her throat. Then she grabbed it by the base and pumped quickly back and forth with her mouth, sucking back the mix of saliva and pre-cum she made.

"Yeah suck it you dirty slut!" Simon exclaimed, and I could tell from the way she spoke about it that she loved the talk. She pulled his cock out and sucked his balls, before he took her into the bedroom.

She lay down on the bed and spread her legs, he mounted her and rammed all the way home in one hard stroke.

"Fuck me hard," Shelley commanded, and he gripped her shoulders and fucked with everything he had. The bed squeaked loudly and banged against the wall, and Shelley loved it. He stopped for a moment to take a breath, before resuming and bringing my wife to a massive orgasm, then squirted his creamy load into her.

"It was a big load too", she told me, "it was still leaking out when I was on my way home." The image of her cum-soaked panties excited me totally.

When she left he grabbed her and said "Next time I'm going to give it to you in the ass." To which she replied, "Who said I do that?". His answer "You did, one night here when you were a bit *****."

The thought of it turns me on, I told my wife that and she was surprised I would want her to go that far. In truth, the further this goes the sluttier I want her to be.

Funny part, she said she didn't even finish her coffee.

**********************************************

Two days after Shelley's second session with Simon, I was out having my monthly golf date with a few buddies. I got home late afternoon and found her a little ***** and giggly. There was an empty bottle of wine on the bench.

"Drink that yourself?" I asked. She said no, she had shared it with Kim. I was intrigued and she explained that Kim and Simon went to a Farmers market near our house, and dropped in unexpectedly. Kim and Shelley opened the bottle and it wasn't long before the conversation got saucy. Which of course led to the bedroom. Shelley confirmed that Kim had known about her and Simon from the start, the night after I fucked Kim they had talked about the possibility of it happening. In fact, they had talked about it several times prior to that also, so me having sex with Kim wasn't as spontaneous as I thought. I think the events at the party that night were the catalyst.

My heart pounded as I thought of a threesome going on in my bedroom, but Shelley told me Kim didn't join in much, she just watched and played with herself as Simon and her got it on.

Shelley sat on the bed with Simon standing in front of her so she could suck him off. Kim stood next to him talking dirty, every now and then grabbing his cock and pumping it a few times. She got off on being watched by Kim. Shelley then stopped naked and lay across the bed, with Simon kneeling upright as he slid inside her. Kim got excited watching her husband slowly fuck my wife.

After a few minutes Simon flipped Shelley onto her knees and took her from behind, while forcing his thumb into her ass. He fucked her pussy steadily while working his thumb in her butt.

"Time to fuck your ass," he said, and Shelley pulled away and grabbed the lube from her bedside table. A few moments later he worked his cock all the way in, Shelley admitting it felt like he was stretching her ass out. With a few strokes she loosened up and he was fucking with a steady rhythm. Kim encouraged Simon and he got harder and faster, eventually getting Shelley to orgasm before he came himself, while still buried deep in her ass. This was the first time any other man then me had ass-fucked her and she was very excited by it. And so was I.

I will admit I was a little annoyed at how soon this happened after their last session, but I did get what I asked for - a slut wife. So far it's only been one other guy, but Shelley seems to be getting off on it a great deal so that might change soon. I hope I'll get to fuck Kim again, and I am still hopeful of a threesome, or perhaps a foursome is on the cards. I could absolutely go for that.
