Her Friend's Ex

"Can I ask you something?" Caitlin was looking at Rob excitedly, a spark in her eyes, her hand holding his. He could tell that she was a little drunk, but then so was he... if you couldn't be a little drunk at your own house warming party then when could you be?

He gave her hand a squeeze. "For my beautiful wife, anything," he replied with a smile.

She looked at him for a moment, her green eyes on her attractive, freckled face, framed by her long dark brown hair, looking intently into his.

"So... you can say no," she said, and Rob noticed that she was blushing.

"Ok... what is it?" he replied reassuringly.

"Ummm... maybe let's talk somewhere quieter." She took hold of his hand and led him out of the packed house and into the garden, the chill of the early spring night air keeping all but the most hardened smokers inside.

"You've got my attention," he said, with a laugh.

She smiled back, a beautiful smile but he could tell that there was something behind it. "I love you so, so much... you know that, right?"

He leaned over to kiss her and said, "And I love you so, so much too."

Rob watched as Caitlin took a deep breath. "You know your... uhh... your secret fantasy that you told me about a few weeks back?"

He felt his own cheeks turn red. "Yes... I over-shared, I shouldn't have done."

"But you did... and I've been thinking about it..."

Rob's heart rate stepped up a notch. She'd been thinking about it? "Ok... and?"

"And..." He could tell that she was struggling to form the words, but had a feeling where this was going. "I'd said that it was a hot fantasy, but I'd never want to try it in real life."

"Yes...?" Rob had a slight smile on his face as he said it. He had admitted when pressed that he'd love to try it in real life, the idea made him breathless. Just once mind you, it wasn't like he wanted it to be a repeat thing. But once would be amazing.

She wrapped her hand around his arm and pressed up close to him, giving him a kiss. She looked so alive at that point, Rob knew something was coming.

"I've changed my mind... I'd be keen to do it just once, if you are still?"

Rob's smile turned into a grin. "Definitely. But when?"

She smiled playfully. "Tonight."

"Tonight?" Rob was surprised. "Like, act out the fantasy at our party?"

"Why not? It would be hot. We could disappear for half an hour and no one would notice."

"Uhhh... ok, like what do we do?"

"You go up to the attic bedroom and wait for me. It's got the lock on the door so that's probably best."

"Ok... that sounds good. I'll go there now?" Caitlin nodded. "Wow... this is fun. Ok, don't be long."

She smiled and kissed him, placing a hand on his chest. "I won't..."

Rob walked back through the party, chatting briefly to a few friends, grabbing a beer on the way through. As he went through the kitchen he could hear Caitlin laugh at something in another room, but left her to it.

Climbing the first flight of stairs, then the second, he went into the attic bedroom and stopped. Caitlin had been busy, clearly, as there were candles lit everywhere, the bed freshly made with crisp white sheets, some music playing in the background.

He settled down with his beer to wait.

Ten minutes later he heard the door open and footsteps coming up the stairs. "You're sure he's ok with this?" came a whispered voice, and he heard Caitlin whisper, "Yes, completely."

Then Caitlin walked through the door, and holding hands with her was a very, very good looking man... tall, handsome, well dressed, well built. She seemed so small and slight next to him, despite standing only a few inches shy of six feet herself.

She gave Rob a shy smile, then drew the man into the room, pushing the door shut behind him and bolting it.

"Wait here," she said quietly to the man, then walked over to where Rob was sitting and whispered to him, "You're sure about this?"

Rob smiled. "Sure," he whispered back. "Just tell me what his name is and how you know him? I've not met him before."

"Henry. He just moved to the area, and used to date Emma when we were at university. Is that ok?"

"Yeah, absolutely. So I just sit here on this chair?"

"If that works for you. I don't think he's down with you joining in."

Rob laughed. "Me neither! I love you."

"I love you too." She leaned over to kiss him, then stood up and turned around before walking back over to Henry.

When she stood opposite him, he leaned over to kiss her, and she kissed him back hungrily. Rob shifted slightly in his seat, realising that not half an hour ago this hadn't even been on the radar yet now he was watching his wife passionately making out with this good looking man.

After a minute or so their hands started to explore each other, Henry's hands reaching for her ass and squeezing, drawing a gasp from Caitlin as he started to kiss her neck, an area that Rob knew just worked for Caitlin in getting her going. Her hands were on his back but then one also went to his ass, feeling him too.

He broke away and, taking her hand, led her over to the bed. As they stood next to it, Henry reached for the white, woollen jumper that Caitlin was wearing and lifted it up and over her head, leaving her in just her black bra, and then reached down to undo the belt and buttons on her jeans, before he slid his hand inside, drawing a louder gasp from Caitlin.

He kissed her roughly as his hand worked inside her jeans, and Rob could see Caitlin really responding, her own hands reaching for his belt and undoing his jeans. God, this as hot as I thought it would be, thought Rob, resisting the temptation to touch himself, hopeful that he'd get his time with Caitlin later.

Henry broke the kiss and pushed Caitlin back on to the bed, pretty roughly, but from the look on her face as she lay there she didn't mind. Clearly Henry liked to be quite dominant in bed, but this was interesting to see for Rob as Caitlin liked to be too... anything remotely submissive wasn't her style.

He reached for her jeans and pulled them off leaving her in just her underwear, a black thong to match her black bra, lying there breathlessly looking up at Henry. Rob realised that if he'd not been there at that moment Caitlin would never have noticed, so completely fixated was she on Henry, looking up at him, biting her lip.

Henry looked at her intently for a few seconds, a look that left no ambiguity as to his intentions. Then he spoke, the first time that Rob had heard his deep voice, almost a growl. "On your hands and knees."

Rob smiled inwardly, just about hiding his derision, knowing that Caitlin simply did not respond to being told what to do. He could see this going south pretty quickly, and mentally was preparing himself already for the 'at least we tried it, never again' chat.

Except, to his complete astonishment, she did exactly as she was told, rolling over on to her front and pushing on to her hands and knees. Caitlin glanced over at Rob, and when he gave a quizzical look she looked away again, unable to make eye contact with him. Hot, thought Rob, but confusing.

Henry climbed on to the bed behind her, dragging down her underwear so that was by her knees, leaving her ass exposed. He quickly unbuckled her bra and it fell down, her size C breasts hanging free. To all intents and purposes she was naked, waiting for him. From Rob's perspective, side on, it looked so, so hot, seeing his wife like that. He'd never had this perspective before and she looked amazing.

Caitlin stole another glance at him, almost an apologetic look, and Rob reassured her with a smile, mouthing, "Are you ok?". She gave a small nod and then looked over her shoulder at Henry.

In the meantime, Henry had unbuckled his own jeans, pulling his rock hard cock out. He had the rest of his clothes on but Rob sat up in surprise at the sight, Henry's large, thick cock noticeably bigger than his own. He saw Henry look at him, and while he and Henry made eye contact Henry slid hard into Caitlin, hands on her hips to pull her on to him, a cry of pleasure coming from her lips.

Henry held himself there inside her for a moment, the juxtaposition of him fully clothed and Caitlin naked save for her underwear around her knees making it even hotter. Then, with a wink at Rob, he pulled back and thrust in to her hard, drawing another half moan, half cry.

From then, his focus shifted entirely back to Caitlin, fucking her hard and rough. Rob was seeing a side to Caitlin that he never knew existed, and he'd never known her to enjoy doggystyle at all... it had always been a position for his enjoyment, not hers. But the noises coming out of her mouth, her erect nipples, how flushed she was, they all told Rob that there was something there that he'd just never managed to unlock.

After a few minutes he saw Henry adjust his hands, moving his left hand to grab Caitlin's hair in a rough ponytail, pulling her head back. To Rob's knowledge she had never been in to anything remotely like that, but she was responding, her moans getting louder, and she didn't seem to mind at all. In fact, far from it, it seemed to push her on.

He saw Henry draw back his left hand and slap her ass, hard, hard enough to make a loud noise and leave a red mark. But rather than complain, or tell him to stop, as the Caitlin that he knew and loved would have done, she simply dug her fingers in to the bed covers and seemed to brace herself against his thrusts harder.

"You like that?" he growled as he planted another slap on her ass.

A pause, and then she replied, "Yes... " A sigh, then, "More please."

Smack. "You want more?" Caitlin nodded and there was another smack. She looked over to Rob and looked away again quickly, her cheeks flushed whether from arousal or embarrassment that he was seeing this side to her he didn't know.

After spanking her some more, Henry tugged on the hair and used his other hand to pull Caitlin up, so that she was on her knees upright, her back against Henry's chest, and he could kiss her neck, Caitlin desperately craning her neck to try to kiss him back, just managing before another hard thrust broke them apart. For Rob, it was insane watching this guy's cock slide in and out of his wife, seeing his balls swinging with each thrust. Absolutely insane, and insanely hot.

And then, Rob got to watch his wife cum, her breathing getting faster, her moans getting louder, until he saw it roll through her whole body, a tremor running through her, her arms tensed and clawing at Henry, while Henry fucked her through it, drawing it out and pushing her through until he let go and she collapsed on her front on the bed, Henry still kneeling behind her.

She lay there, seemingly stunned, for a minute, then she turned her head to look at Rob, a look that was entirely unfathomable and unreadable. It was intense, it was serious, but somehow her eyes still said that she loved him, as if through that look she was thanking him for making what just happened happen.

Behind her, Henry had climbed off the bed and taken off his clothes, standing naked, his still rock hard cock standing proud and heavy from his body. He was in great shape, a body that many men could only dream of having, toned and muscular without being over-worked. Rob could see why Caitlin would have chosen him for this.

In fact, Rob had to admit that despite being an entirely straight man, he was having a few thoughts of his own at the sight, there was something so carnal, so erotic, so powerfully dominant about him. Rob realised with a thrilling shock that if Henry had told him to, he'd have had little hesitation in helping him out with that erection... a thought so alien and forbidden to him that he felt himself hardening even more to think it.

But Henry didn't. Instead, he lay down on the bed and said to Caitlin, "Come here."

Again, she didn't object and simply obeyed, pushing wearily off her front and turning round, on her hands and knees again, between his legs. She wasted no time in taking his cock in her mouth, and Henry reached down to bunch her hair up again to keep it out of the way, using his hand to control her pace. Again, this was something she never let Rob do, another unexpected side to his wife. And again, so so hot.

It didn't take long, but as Rob saw Henry start to cum he also saw him pull Caitlin's head down on to his cock, making her take as much as she could in her mouth, and he saw her struggling slightly to take it, and then it was over, and he saw some of his cum dribble out from her lips along with a long line of spit as she finally left her head away, catching her breath.

"Good girl," said Henry, stroking her head. "But I'm not done with you."

Caitlin turned her head to look at Rob. Catching her breath, she said, "Is that ok with you?"

Rob forced a smile, although a part of him was thinking that this could get ridiculous. "That's fine, just remember the party though."

She smiled wearily back. "We won't forget..." Then she looked at Henry and moved up the bed until she was leaning over him, kissing him, a kiss that he returned hungrily.

After a few minutes of them kissing and cuddling each other, Rob could see the excitement build again, Henry's cock hardening in Caitlin's hand and Caitlin starting to shift her hips slightly against Henry's fingers which were between her legs.

At that moment, the smoke detector downstairs started going off. Rob stood up and Caitlin looked over at him. "You want me to go?" she asked, cheeks flushed.

"No," replied Rob. "You two keep going, I'll be right back."

He unlocked the door and went back downstairs to the sound of sighs, and moans, and what sounded suspiciously like the wet noise of his wife being fingered hard.

It turned out that one of the guests had decided to make some food in the oven, but then forgot about it so there was smoke everywhere. Rob spent maybe ten minutes getting it all sorted, all the time desperate to get back upstairs, it almost eating at him wondering what this dominant character Henry was doing to his wife.

When it was all sorted he got collared by Caitlin's friend Emma just as he was trying to go upstairs. "Have you seen Henry at all?" she asked. "We're supposed to be giving him a lift home but I've not seen him for a while."

"Henry, as in your ex?" Rob replied with a teasing smile. Emma was long married and had left her university years far behind, but their friendship was one where some light teasing about their history was not a problem.

"Barely," laughed Emma. "I don't think two weeks seeing someone after Fresher's Week counts as an ex! No, you know... Henry as in Henlin."

"Henlin?"

"Oh, I forget sometimes that you and Caitlin met after. Yeah, Henlin was the nickname we all had for Caitlin and Henry, they were inseparable for all those years."

Rob forced a grin and played it cool. "Never heard that name, they were together for most of uni weren't they?" He was guessing here, Caitlin had always been vague about her love life before they met, but this felt like something he needed to know.

"Yeah, like three and a half years. We always thought they were the couple that would live happily ever after, you know, marriage, babies the works. But they split up because he wanted to move overseas and she didn't." She paused and laughed. "But you're much better, don't worry. He could be pretty intense but I don't think you've got anything to worry about here."

"Well, I'll tell him you're looking for him if I see him."

"Thanks."

Rob went back upstairs, his mind turning this over. It went without saying that Caitlin hadn't been entirely honest with him, getting him to agree to what was going on upstairs at that very moment under somewhat false pretences. He'd need to talk to her about that, without a doubt.

But... he'd not told her, but the real core of his fantasy wasn't that she was having sex in front of him with a random guy, it was that she was having sex with an ex-boyfriend. That feeling of being supplanted, being put in his place, being lower down Caitlin's pecking order from someone else, it turned him on so much. It was so hot.

So for that to be what was happening at that moment was, well, interesting. His wife was fucking her ex-boyfriend with his permission. Her hot, dominant ex-boyfriend. That explained for Rob why she was so willing to be submissive to him, to be so out of character, if that had been the dynamic between them all those years ago. He was sensible enough to realise that that was maybe something that was her fantasy, and he was helping her to fulfil it.

Rob decided to go upstairs quietly, just in case he could glean anything else. As he tiptoed up the top flight of stairs the sounds of the party died away beneath him, and the door stood ajar as he'd left it when he went downstairs.

He settled himself quietly on the top step and listened. To start with, all he could hear was the sound of, well, fucking. His wife being fucked by her ex. A little pang of jealousy hit him, accompanied though by more than a little pang of arousal. To be honest, it sounded good - a rhythmic creaking of the bed, an occasional squelching noise speaking to Caitlin's arousal, moans and the sound of kissing. They were having fun.

Then, he heard Caitlin say quietly, "Oh Henry..." A moan. "Oh..." Another moan. "You always knew how to fuck me..." Another moan. "I've missed this..."

Not ideal, thought Rob, that Caitlin had been missing sex with another man. But maybe an opportunity, if they were open and honest, to vary what they did. There was no reason that Rob couldn't do to her what Henry clearly did.

"We'll do this again," came Henry's breathless reply.

"We can't," replied Caitlin. Another moan. "This is just tonight, just because Rob said we could." A louder moan as Rob heard the pace increase. "I'm not..." Another louder moan. "I'm not going to cheat on him."

Hmmm, thought Rob, this is kind of borderline. But he was glad to hear her say it, they'd clearly engineered a situation to scratch an itch, but she was making it clear that they weren't doing it again. He was ok with that, although he planned to make use of his knowledge of what was really going on at a later point.

Satisfied that he'd heard what he needed, Rob went back downstairs quietly, then made a show of loudly coming up stairs again. As he walked in, they were fucking in missionary position, Caitlin an absolute picture of the submissive lover, her legs apart and wrapped around him, her hands pinned above her head at the wrist by one of his hands, really close to orgasm.

She looked at him as he came in, and Rob liked to think that that pushed her over the edge. Certainly, whatever it was drew her into a huge orgasm, cries of pleasure coming from deep inside her as Henry continued to fuck her through it, until she finally pushed a hand against his weight and told him to stop.

After a few moments, Rob said, "It's been great, but I think we need to call it a day. People are wondering where you guys have got to."

Caitlin smiled at him, a happy, glowing smile, and despite what he'd discovered Rob felt nothing but love for her. "I love you," he mouthed, and she mouthed back, "I love you too."

Henry looked up at Rob and said, "Give us a minute. Sit down, I'm not finished."

Without realising, Rob obeyed, there was something about Henry that had such gravitas, such presence, that you automatically did what you were told. He'd just been told by his wife's ex-boyfriend to sit down and let him finish, and he secretly loved it.

Henry looked back down at Caitlin, a significant look, something passing between them that came from their own secret set of looks and understandings from all those years before. He reached his arms down, moving her legs on to his shoulders, and from his vantage point Rob saw him pull out of her and position himself a few centimetres lower.
