Ian walked into the kitchen, where his wife Kelly was preparing lunch. He embraced her from behind and kissed the side of her face. "Hiya sweetie," he said.
She turned in his arms and kissed him open-mouthed, thrusting her tongue against his.
"Well that was a bit unexpected," he said, once they'd eventually stopped seemingly trying to eat each other.
"Sorry. Well, not sorry, but you know what I mean."
Ian noticed her flushed face and, glancing down, could clearly see her nipples straining against her tight white t-shirt. She seemed massively turned on for some reason.
"You okay?" he asked.
"I'm so fucking horny you wouldn't believe," she said. "I was talking to Charlie earlier." Charlie was the eighteen year old daughter of the couple next door. "I could swear she was coming onto me. She was telling me about her boyfriend, then started talking about previous boyfriends. And girlfriends."
Ian's eyebrows rose. " Really?"
"Yeah, she then told me that all her previous girlfriends and boyfriends had been her own age, or thereabouts, and that what she really wanted to do was try it with an older woman. Or an older man. Or both. I gotta tell you, I started to get a bit moist and my nips just pinged out. You know I can't control the fucking things." She peered down at her chest where the fabric was very obviously dented.
"Did she notice?" Ian asked.
"Well, going by the way she stared at them, yes she did. Couldn't take her eyes off them."
"Wow," Ian said.
"Then, she went bright red and said she had to go home. I was kinda disappointed. I was just about ready to jump on her."
Ian laughed. "Well, you've never been backward about coming forward have you?"
In their fifteen years of marriage, they'd had a number of dalliances with other women. Either Kelly by herself, or with the both of them.
"Actually," Ian said. "I know exactly what you mean. I was mowing the lawn the other day and she came out to do a bit of sunbathing wearing the tiniest bikini you've ever seen. There were tits everywhere! She wandered over and started chatting. I had to hide behind the lawnmower so she wouldn't see the massive bulge in my sweats."
"You know what? Bollocks to lunch," Kelly said. "Let's go upstairs."
While they were upstairs, they told each other what they would do to Charlie if they could get their hands on her. They came up with a plan for Ian to submit to her seduction then have Kelly 'surprise' them together.
A Few Days Later
Charlie moved slowly up and down on Ian's cock. Ian gripped her hips, trying to force her to go faster, but she wasn't having it and grabbed his hands and moved them to her forty inch tits, nipples aching to be caressed. Ian obliged and filled his hands with them, kneading them and pulling on the thrusting nipples.
"Well, this is all very friendly," came a voice from the doorway.
Charlie let out a little yelp as she looked at Ian's wife, Kelly, and tried to climb off of Ian. Ian, however, wasn't willing to let her go and grabbed her by the hips once more, forcing her down.
Kelly approached the bed, unfettered tits jiggling against the semi-transparent white silk blouse and the nipples denting the fabric, until she stood at the side, within reach of Charlie. Kelly looked her up and down, lingering on her tits. Eventually, she reached out and ran a palm across one of her erect nipples.
"Very nice, " she whispered. "Very nice indeed."
Charlie looked down at Ian, who just grinned at her. "What the fuck?" she asked.
"Kelly told me about the little chat you had the other day. And I told Kelly about you flirting with me when you were sunbathing last week."
Charlie looked at Kelly, eyes flicking down to her tits. "Oh, you like them do you?" Kelly asked, following Charlie's gaze. She cupped her tits and squeezed them so that they bulged against the flimsy covering, the nipples poking against the cloth. She moistened a finger and ran it around a nipple until it was clearly visible through the blouse.
Charlie's breathing deepened as Kelly moved closer to her, bending slightly so that her nipple was millimetres from Charlie's mouth. Charlie poked her tongue out and licked at the nipple, then closed her mouth around it and sucked it into her mouth.
"Suck it, flick it with your tongue. You've been dying to get them in your mouth for ages haven't you?" Kelly said. Charlie did so, then switched to the other, while Kelly reached down and grasped Charlie's tits and started to massage them, flicking and rolling her fingers around the jutting nipples.
Kelly pulled back, leaving Charlie, still impaled on Ian's cock, gasping in erotic pleasure, mouth open. Kelly bent and clamped her mouth onto Charlie's, sucking the tongue into her mouth. She reached down once more to maul at Charlie's tits, then broke off the kiss and her mouth latched onto Charlie's nipples, one after the other, sucking them into her mouth and rolling her tongue around them. She drew back and blew gently, causing the aureoles to crinkle from the cold and making the nipples even more erect.
