Christine Haversham was a bit mixed up at the moment. Since she had suspected and then had confirmed the relationship between office colleagues Ruth Edrich and Liam Tabram, she had thought of little else. The fact that eighteen-year-old Liam was thirty years younger than Ruth, and indeed twenty years younger than Christine, seemed to be the main reason for her interest. That and the sight of the large bulge in Liam's trousers that she saw when she first actually saw him and Ruth in physical contact.

Christine was married but her sex life with her husband Tim was okay at best. Tim usually came before Christine was even close to sexual satisfaction so, in her head at least, she was wanting some of what Ruth was getting.

Ruth, and a couple of others, were in the office on Monday morning when Christine arrived. "Morning, Ruth, did you have a nice weekend?" Christine smiled although they both knew that what she was asking was had Ruth been well fucked.

"Yes thanks, Chris. Friday night and Saturday morning were great but a bit quiet since," replied Ruth, responding regarding the subject that Christine was really asking about.

"Wow! He stayed Friday night?" said Christine regarding this new revelation.

By now, other people were arriving in the office and eight of the ten total staff were now there but as yet, no Liam. Everyone else knew that Ruth and Liam were together but it was only Christine that seemed to have a great interest in the relationship.

"Was your weekend good, Chris?" Ruth asked without answering Christine's question although that question did not really need answering.

"Certainly not as good as yours," replied Christine as Liam and also the tenth member of staff arrived.

Liam and Ruth just smiled at each other and stroked each other's arms but they both really wanted to kiss. Despite their relationship being out in the open, they knew not to be too demonstrative about it.

"Alright, love?" asked Ruth with her eyes fixed on Liam's.

"Yes, are you?" responded Liam.

"Yes, talk at lunchtime," replied Ruth because they knew that they must not let their work be affected in any way.

Although the office knew, Liam's parents did not and he and Ruth wanted to keep it that way. It did restrict their nocturnal activities and Liam's mother had grilled him both before and after the Friday night assignation about who he was spending the night with. Susan Tabram would certainly not be pleased if she found out that her son's 'girlfriend' was actually five years older than she was.

Lunchtime arrived and as the weather was good, Ruth and Liam headed for the park. As they went out of the office door, Ruth's eyes met Christine's and Christine flashed a knowing smile that Ruth acknowledged in kind.

The first two visits to the park at the start of the previous week had seen Ruth masturbating Liam to ejaculation but they had decided that the risk of being caught did not make that viable now that they had opportunities for undisturbed sex in Ruth's house. They did walk hand in hand though and occasionally kissed. Ruth had been mulling over Christine's obvious interest for a while and she surmised that the interest went as far as Christine wanting to bed Liam.

"I think Christine fancies you," Ruth said to Liam, which was a bit ironic because it was Christine that had told Ruth that Liam had got the hots for Ruth before they actually got together.

"Does she?" replied Liam who, although he only had eyes for Ruth, actually thought Christine very sexy.

"Yeah, would you fuck her if you had a chance?" said Ruth, not knowing herself quite where such a question might lead.

"I am with you, aren't I?" said Liam, a bit concerned because he thought that Ruth might be passing him on.

"Yes baby, but would you fuck her if I said it was okay?" pressed Ruth.

"I don't understand. What are you two planning?" replied Liam, still not indicating whether he would or would not shaft Christine.

"We are not planning anything and I am not certain that Christine wants to go that far. But if she did and I said it was okay, then would you fuck her?" persisted Ruth.

"Well, yes but I don't want to lose you," replied Liam who now had the potential prospect of a second older woman to fuck.

"I do not want or intend to lose you either, baby, but are you okay with me talking to Christine about it?" said Ruth.

"Yes, I am okay with that," said Liam although he still sounded as though he had doubts. Actually, the doubts that he was having were not about whether he wanted to fuck Christine because that was certainly a 'yes' but about what it might do to his relationship with Ruth.

They walked and talked some more, and occasionally kissed, and on Ruth's suggestion, Liam phoned his mother to say that he would be home at about ten but would eat whilst he was out.

Ruth got back to the office about ten minutes before the end of the lunch break and was pleased to see that Christine, but nobody else, was there. "Can I talk to you about something, Chris?" asked Ruth with quite a serious face.

"Oh dear, have I gone too far with things that I have said about you and Liam?" said Christine, also seriously.

"No you haven't, but, um, it is about me and Liam and... um, you," said Ruth, trying to choose the right words.

"Fuck, what does that mean?" said Christine.

"Actually, that is a very good word, I might be reading you wrong but, um..." started Ruth but she was now stuck for what exactly to say.

"Shit, Ruth, what are you trying to say?"  said Christine.

"Do you fancy Liam, like want to fuck him, type fancy?" blurted Ruth.

"Are you serious?" replied Christine.

The trouble was that now a few people were drifting back from lunch so Ruth ushered Christine outside, "Yes, I am serious. Would you like to go to bed with him?" said Ruth once they were out of the office.

"Fucking hell, Ruth! Sex at home is nothing special and Liam obviously gives you a good fucking so yes, yes I would, but how can that happen?" responded Christine.

"I have spoken to Liam and he would like to give you one and I am okay with it, so why not?" said Ruth.

"Shit!" was all that Christine could immediately say in response.

Ruth laughed and then asked. "Is that a yes or a no?" giggled Ruth.

Christine briefly felt guilty about her husband but then laughed and gave an unequivocal response. "It is a yes, a fucking yes," she smiled.

"Is tonight after work, my house, too soon?" asked Ruth.

Christine thought that that was amazingly quick but did not say so. She was thinking that if she turned down the chance, she might not get another one.

"Not sure, I will let you know," replied Christine who had two early to mid-teens kids, not all that much younger than Liam, to think about.

They had to now go back into the office because lunchtime was over but both women looked at Liam, both knowing that he would be fucking them soon but in one case, for the first time. Liam looked back because he assumed that Ruth had been in conversation with Christine about the possibility of him fucking her. Liam could not work out the result of the conversation by the women's expressions though.

Christine gave the possibilities for the evening some thought and eventually sent a text to her fifteen-year-old daughter saying that she was spending time with some friends after work and for her and her brother to get their own tea. Christine also sent a text to her husband saying something similar and although she felt some guilt, she did not think that she really felt enough.

She let Ruth know that this evening was fine and Ruth let Liam know that he had a second woman to fuck after work.

After work, Liam went with Ruth in her car and Christine followed in hers. "You are alright with this aren't you?" Ruth asked Liam.

"Yes, if you are," replied Liam.

"It seems like I am hiring you out as a stud," laughed Ruth.

"I suppose there are worse things to be. Are you going to watch?" responded Liam.

"Fuck, I don't know, I had not thought about that. Do you want me to?" answered Ruth.

"Don't know, if you want to, I suppose," replied Liam.

By now they were at Ruth's house and the issue of whether or not she was going to watch had not been resolved. Christine, in her car, had been feeling all sorts of things on her journey with apprehension, guilt and confusion among them but mostly she felt aroused.

The strange thing was that at no point had Christine and Liam spoken directly to each other about this but here they were, in someone else's house, about to fuck. They looked slightly nervously at each other inside Ruth's house and Ruth decided that she had better move things on. "You two are going to be fucking in a few minutes so I think that maybe you could kiss," said Ruth.

Both Christine and Liam smiled at Ruth and then moved towards each other and kissed. Very tentatively at first but then with more passion and hands started to roam. Ruth was not surprised to see Liam's hands go to Christine's skirted arse because he tended to grip Ruth's buttocks early in a snogging session. Christine was thrilled to feel Liam's expanding bulge pressing against her.

Ruth then set out the plan, or at least the plan as she saw it. "I am going to let you two go upstairs and I will leave you alone but I may come up there after a while if that is okay," said Ruth to the couple who each still had arms around the other.

Ruth then thought that she had better clarify her intentions. "If I do come up I will not get involved, just watch," she said and the other two seemed happy enough with that.

"Um, my Tim has had a vasectomy so, um, I can't have spunk inside me," said Christine but she said it sort of generally and not directly to either Liam or Ruth.

"Yeah, Liam will pull out before he cums. We would not want your teenage kids getting a surprise baby brother or sister, would we?" laughed Ruth, just in case Liam had not understood the implications of what Christine had said.

The preliminary arrangements were seemingly completed so Ruth sent Liam and Christine upstairs. "You two go and have fun, give her a good fucking, Liam," said Ruth although she felt strange saying it. It was almost exactly one week to the minute since she and Liam had embarked on their first fuck.

"I will," confirmed Liam as he and Christine went up the stairs.

Christine and Liam were still a bit tentative when they reached the bedroom. "You do want to do this, don't you?" Christine asked Liam.

"Yes, do you?" Liam responded.

"Yes, so let's fucking do it," replied Christine before locking her mouth on Liam's and shoving her tongue into it. Christine was caressing Liam's cock through his trousers as his hands went to her arse again.

They broke from the kissing and both sets of eyes were ablaze, particularly Christine's. Christine took off her blouse and then her bra and Liam removed his shirt. Christine then unfastened Liam's trousers and lowered them and then fondled his erect cock through his boxers. "Fuck you are big. No wonder Ruth is so happy," said Christine.

Liam now undid Christine's skirt and it fell to the floor. He briefly caressed her tits before fingering her cunt through the wet patch in her knickers.

"Oh shit, I need your cock," said Christine as she pulled Liam's boxers down and as he struggled out of them and his trousers, Christine removed her knickers. Liam noted that she was slightly less hairy than Ruth but her cunt glistened just like Ruth's did when she was ready to go.

They crashed onto the bed and Christine guided Liam's big cock into her cunt and she groaned as he entered. "So fucking big," she muttered as Liam slid deeper into her.

Downstairs, Ruth felt a bit strange because the sounds from above indicated that her lover was embarking on fucking her friend but she had, to all intents and purposes, arranged it. She also felt very turned on.

Liam was now fucking Christine quite fast and she was fast heading for something that she had rarely had in recent times during intercourse, an orgasm. Christine sighed and groaned as the young man with a penis noticeably bigger than her husband's continued to drive her towards sexual release.

"Mmm, fuck, yes, yes, yes," wailed Christine as the orgasm duly arrived and Ruth downstairs now had her hand inside her knickers touching her wet cunt.

"Oh fuck, yes," Christine shouted even louder soon after as she came again and then there was a change of position with Liam fucking her from behind. Ruth was now stood in the bedroom doorway without the two on the bed knowing it, and her fingers were working fast in her knickers.

Her friend was on her hands and knees and panting and groaning as her also panting young lover fucked her from behind. Ruth studied Liam's backside as he thrust in and out of Christine and Ruth was about to cum in her knickers.

Christine came again and Liam was close to doing so but he remembered his instructions. "Gonna cum, where do you want me?" he breathed heavily.

"On my arse, cum on my arse," panted Christine in reply and Liam withdrew, only just in time, and started spurting spunk over Christine's buttocks. Ruth duly came in her knickers and her groan made the other two aware of her presence but neither of them looked at her because they were both still lost in their own thoughts.

All three of them were breathless, although Ruth to a lesser extent, as Christine collapsed on her front on the bed with semen splattered all over her shapely backside. "You are right, Ruth. He is fucking amazing," Christine acknowledged as a contented Liam sat on the bed with a slight smear of semen on his thigh and his cock sticky with Christine's cum.

Ruth removed her skirt because she did not want her cum soaked knickers wetting the inside of it. "Yeah, it seems that you enjoyed it," smiled Ruth.

Christine then turned her head towards Liam. "Thanks for the fuck, Liam. It was sensational," said Christine.

"Thank you, Christine. I loved fucking you," said Liam who before the previous Monday had only had sex with a seventeen-year-old girl and now he had given two mature women a good fucking.

Ruth, meanwhile, was having trouble taking her eyes off Christine's spunk-streaked arse and she was thinking what a gorgeous arse it was. Ruth had no sexual experience with another female apart from a bit of fumbling with a fellow seventeen-year-old schoolgirl when at boarding school but she was starting to feel stirrings regarding Christine Haversham.

"What time are you due home, Chris?"  Ruth asked her friend, having at last taken her eyes off her arse and looking at her face.

"Didn't say, but I had better not be too late," replied Christine who was now breathing almost normally.

"I think you had better have a shower, especially to get that cum off your backside," suggested Ruth.

"Yeah, I think I had better, where is the bathroom?" replied Christine who was now feeling just a tinge of guilt again.

"Just down the hall. Towels are in the cupboard over there," said Ruth who then found her eyes on Christine's tits as her friend approached her to go out of the doorway where Ruth was standing. Christine gave Ruth a sexy smile as Ruth stepped aside.

"So, lover boy, did you enjoy fucking Mrs Haversham?" Ruth asked Liam with Christine having left the room, although the answer was pretty obvious.

"Yes, it was good," replied Liam who actually thought it better than good but decided not to say that.

When the naked Christine returned after her shower, Ruth was sat on the bed with Liam. She was still clothed other than the removed skirt. "I suppose I had better go home," said Christine who was seeing all sorts of sexual possibilities for now and, hopefully, the future.

"I suppose," replied Ruth who then watched her friend re-clothe her very sexy body.

"Are you going to let me get out of the house before you fuck?" asked the now dressed Christine seeing that Ruth was slowly wanking Liam's erect penis.

"Stay and watch if you want, but then you would probably need another shower," replied Ruth.

"Yeah, better go. See you both in the morning," said Christine who really wanted to stay.

"Yep, I will see you out," said Ruth, letting go of Liam's cock and getting off the bed.

"Bye Liam, thanks again," said Christine as Ruth seemed to usher her out of the bedroom door.

"Bye Christine," replied Liam who knew that he would be fucking Ruth very soon.

Ruth opened the front door for Christine and the two women kissed. It was lip to lip and only gentle but it seemed to come naturally to them both. "See you, Ruthie," said Christine.

"See you, Chris," replied Ruth whose eyes went to Christine's skirted arse as she went to her car.

With Christine having gone, Ruth was back upstairs and quickly got herself naked and on her back as her young lover slid into her. Liam made long and slow love to her and had her cumming three times before he spurted into her.

They chatted for a while after the sex and concluded that neither of them had any regrets about bringing Christine into their lives in such a way as they had.

Liam then showered and Ruth dropped him in town for him to get something to eat before he went home. They would meet again at work in the morning but now the arrival of Christine Haversham, very much on the scene, conjured up all sorts of future possibilities.
