Fill In

I was at home doing nothing very much when I received a call from Adam Baxter. Would I, he wanted to know, be available for a babysitting job for some friends of his on Saturday afternoon? Not having anything else that I really needed to do I agreed, first making sure that they knew what my rates were.

I fronted up and found that Adam was already there. He invited me in and introduced me.

"Carleen, meet Ella and Charles. Charles, this is the young lady I mentioned. I think you'll find that she'll meet your requirements admirably."

Ella and Charles were in their mid-twenties by my reckoning. Ella was a blonde, the genuine thing from what I could see, with a very pretty face and an absolute wow of a figure. She was a D quite easily, possibly even better endowed than I was, and I had a nice set of Ds myself. She was also dressed to highlight her figure. Geez, the way she was dressed was almost an invitation to rape.

Charles was dark to her fairness, big and muscular, not over muscled so much as looking extremely fit. Fit the way a star athlete was fit rather than a gym-rat.

"Do you remember the bonus you earned the last time you sat for Marg and me," asked Adam, and I gave him a startled look. Of course I remembered the bonus. The trouble was I also remembered what I had to do to earn it. Well, not had to, but I certainly earned it.

"I see that you do," said Adam with a smile. "Well, I will pay you the same sort of bonus if you provide the same sort of service for Charles."

I gave him another startled look, my eyes flicking over to Ella and back.

"Oh, don't worry about Ella. While you're playing with Charles I'm going to strip Ella and play with her. It'll be fun."

All three of them were looking at me now, smiling.

"What the hell?" I demanded.

"It's quite simple," Adam said. "I want to fuck Ella. She's agreeable and Charles doesn't mind on one condition. He wants someone he can fuck at the same time. Now you know Marg. There's no way she'd be agreeable to do this, but then I remembered you. The position seemed ideal for you to act as a fill in. Are you in?"

He was asking me to be part of a foursome? I didn't believe it. OK, not a foursome as much as two twosomes, but I didn't even know Charles. What if he got nasty? What could I do then?

"If you're worried that I might want you to do something kinky," said Charles, "This is as kinky as we get. Getting a couple of extra partners for some straightforward fucking. No bondage or anything like that. You won't have to do anything you don't want to, although getting fucked is obviously part of the deal."

I dithered, not knowing whether to run or to actually do it. I was tempted, really tempted, but I didn't want to find myself in something I couldn't get out of.

Adam spoke up. "She's interested, Charles, but you're going to have to talk her out of her clothes. To help you along I'm going to strip Ella right now and start on her. See if that will help Carleen make up her mind."

With that Adam turned to Ella and started taking off her clothes. She giggled a lot but didn't do anything to stop him. As soon as she was naked Adam ran his hands all over her, and then started stripping himself.

When they were both naked Ella turned around and leaned forward, bracing her hands on her knees. Adam moved up behind her and just slowly pressed against her, sliding his cock into her. He didn't worry about any foreplay, just pushing home and Ella just seemed to lap it up.

I turned to look at Charles to see how he was taking the sight of his wife being fucked. To my surprise he was also naked, looking at me and smiling.

"Would it help if Adam came over here and started you off?" he asked.

"What do you mean?"

"Just what I said. You take your clothes of and Adam comes over and does to you what he's currently doing to Ella. I'll keep Ella busy for a few moments until you're ready to switch from Adam to me."

Oh my lord, and I thought I was ready for sexual shenanigans. I was, but I'd never imagined this sort of scenario. I mean, I'd never seen another woman getting fucked before. It suddenly came to me that I was acting in a very naïve way and possibly looking a little silly. I mean, I had screwed Adam the first time he asked me.

"There's no need for that," I said, and started undressing. I have to admit that at least part of my decision was influenced by the erection that Charles was sporting.

"Very good," said Charles once I was naked. "Why don't you go and stand the same way Ella is standing, facing her."

I did so, bending over slightly, bracing myself with my hands on my knees. Looking forward I was face to face with Ella and she was giggling and smiling. I could sense Charles moving up behind me and then his hand was rubbing my vulva. It seemed only moments passed and he was parting my lips and sliding into me, driving in quite firmly. I was, I found, sufficiently aroused to take him with no problems.

I could see that Adam was slowly pumping back and forth, fucking Ella, but in no hurry to do it. Where I was concerned I could now feel Charles doing exactly the same thing, slowly sliding back and forth, fucking me but in no hurry.

I was rather surprised when after a few minutes and a word from Charles both men withdrew and stepped back.

"OK, girls," said Charles. "On your hands and knees, next to each other."

I simply got down on hands and knees. Ella moved over next to me and did the same, both of us facing the same way. Adam and Charles moved around behind us. I waited and then a cock came driving firmly into me.

"Hey," I squealed. "That's Adam, not Charles."

"Told you she'd pick it," said Adam, withdrawing.

Moments later another cock came charging home and this was definitely Charles. Adam didn't start straight in on Ella though. He had her turn so she was facing the other direction, her bottom level with my head. Then he was kneeling behind her and thrusting in. I could see his cock surging into her and presumable she could see Charles's cock making time with me. I'll swear the men were timing their moves as Adam seemed to be thrusting into Ella at the same time as I could feel Charles thrusting into me. It was rather a strange sensation.

They kept on in this position for a while and I was building up quite a nice arousal. I was pleasingly hot and bothered, enjoying what Charles was doing. And then they stopped doing it. They both pulled out and I don't know about Ella I was feeling frustrated.

"Ok, lie on your back," said Charles, and I rolled over, seeing Ella do the same. Charles promptly took hold of my ankles and lifted them high, effectively bending me in two. I had a clear view of my pussy and it was blatantly evident as to what had been happening to it. Now Charles lined up and drove into me, hard and fast, and I was treated to the sight of his cock plunging repeatedly into me. I assume that the same thing was happening to Ella but I was only concerned with my own body at this stage.

Once again my arousal started creeping towards a climax while I watched Charles bouncing off my groin, his cock sinking deep with each bounce. I was most definitely going to climax this time, I just knew it, so you can imagine my frustration when he pulled out again.

"What do you think you're playing at?" I demanded. (Demanded is an euphemism for screamed.)

"Now be reasonable," said Charles chidingly. "We don't want things to finish too soon, do we?"

"Yes," I snapped, and he laughed.

"Don't worry. You'll get there. We take a little break between each position and that allows our arousals to die down a little and we can start building them again. You'll get used to it."

I flicked a glance at the clock on the wall and to my shock I found that what with one thing another and changing position Charles had been fucking for nearly twenty minutes. That was so unfair. Men aren't supposed to keep on going like that. Adam sure hadn't when he'd fucked me. Was he still going?

A quick look around told me the answer was yes. He was no longer following Charles' example but had Ella bent over a chair and was just fucking her for all he was worth. He wasn't going to last much longer.

Charles pulled me to my feet and eased me over against a wall.

"Lean on the wall and lift one leg up," he said.

As soon as I did so he grabbed my leg and steered it around his waist. This meant that I was wide open to him and he didn't take long to take advantage of that fact. He drove firmly into me and then continued with a nice slow rhythm, thrusting in and slowly withdrawing. It was exciting, it was arousing, it was absolutely and totally frustrating. I wanted his cock to come pounding into me, to drive me before it, removing any inhibitions that I might have, and then forcing me to a climax whether I wanted it or not.

"Will you cut out the crap and fuck me," I wailed, starting to become furious beyond reason.

"Well, when you put it that way," said Charles.

He pushed me down onto the floor, spreading my legs and lying on top of me, his weight crushing me against the floor in a pleasing fashion. His cock came driving into me, his hands were on my breasts, mauling them, and he finally started driving into me in earnest. I was squealing and carrying on, bucking under him, taking all he could give me and demanding more, more, more, which he seem happy to give.

Then I was climaxing and it had been worth the wait (sort of) and he was jerking about as he sprayed my cave with his juices.

When he rolled off me Ella dragged me down to the bathroom for a quick shower. I came back wrapped in a towel. Silly, really. Everyone had already seen everything I had. Charles handed me an envelope.

"Adam said to give you this. He says you'll know what it is."

Too right. My babysitting bonus, and boy had I earned it.

"Well I guess I'll get dressed and be on my way," I said and Charles had the gall to look surprised.

"Why would you be leaving so soon?" he asked. "Give me half an hour to recharge and we can try again."

Again? Was he kidding? By my reckoning he'd been fucking me for a good half hour. I promptly pointed that out to him.

"Half an hour? Was that all? In that case you definitely have to stay. I'm sure we can better that performance with a bit of practice."

I glanced at Ella to find she was smiling and nodding.

"If we take it in turns we should be able to keep him on the boil for an hour at least," she said happily. "You can't leave without trying."

Curiosity will be the death of me. I found I really wanted to know if Charles could sustain an erection for an hour while two women were taking turns bouncing on it. Just as an experiment, you understand.
