For a few seconds after I woke, I didn't know where I was. This wasn't our bedroom, and Anne wasn't next to me. Then I realized that I was in the spare room. Last night I'd come back late. I'd been drunk, but I'd still had the good sense to sleep here so as not to disturb her. But then I remembered that I hadn't needed to. I'd forgotten that she was staying with her Mother. Today was Saturday, and she wouldn't be home until tomorrow evening.
Surprisingly, considering the large quantity of alcohol that I'd consumed when I'd been out with my friends, I was feeling OK. But then I made the mistake of sitting up. My head was now pounding, and it was taking all of my self-control to stop myself from being sick. Then I groaned, and not because I was hung-over, but because of what had happened last night. It was all coming back to me now. Fuelled by the drink and my boastful nature, I'd talked about Liza, my Mother-in-law. I'd told my friends that she was attracted to me, and that if I wanted to, I could have her. And my language hadn't been subtle. I groaned again when I remembered the exact words that I'd used.
"All I'd have to do is put my hands on her big tits, and she'd then be begging me to fuck her."
If Simon hadn't laughed, then that would have been the end of it. But he had, and it had irritated me. Its meaning was obvious to all of us. He didn't believe me. So when he offered me the wager, I readily accepted it, confident that I would win. Now, in the cold light of day, I knew that it was a mistake. And I'd even made it worse later on, when after several more drinks, I'd insisted that we double the bet. Simon had grinned at me, and then he'd quickly accepted. As far as he was concerned, this was a way of making some easy money. And I was now beginning to think that he was right. Last night I'd been confident, but that was because of the alcohol. I have a good relationship with Liza, but she's never given me any indication that she wants it to become in anyway sexual. Now, if I didn't make good on my promise to bed my Mother-in-law, then I would have to pay him four thousand pounds. It would make a sizeable dent in our savings, and because it was Anne who looks after the household accounts, she would definitely notice.
As well as a throbbing headache, and the urge to vomit, I now had a sinking feeling in the pit of my stomach. I was definitely going to lose. I could kick myself. I was twenty five years old, but I'd acted like a teenager who couldn't handle the booze. Anne was only twenty two, but in a lot of ways she was more mature than me. I just wish that I was more like her. If I was, then I would never have made that stupid bet.
By midday I was feeling a lot better, but even though I was hungry I didn't dare eat, because I wasn't sure that I could keep it down. Instead I had some more coffee. As I drank it I thought again about the bet. I still couldn't believe how stupid I'd been. But there must be something that I could do about it. What if I waited for a few days, and then I told him that I'd been successful? He'd believe me, because he trusted me. But I wasn't prepared to sink as low as that. And just thinking about doing that was making me feel ashamed. Then I had another idea. I might be able to get out of it. I could ring Simon, and laugh it off as a joke. I'd have to do some serious grovelling, and I'd certainly lose face with him and my other friends, but it would save me a lot of money.
I got as far as selecting his number, but I was too proud to call him. In two weeks' time I'd have to admit defeat, and pay up. I'd make out that losing was no big deal. I'd tell him that I'd come close, but we hadn't actually fucked, so he was the winner. I'd even smile, and shake his hand, as I gave him the money. And I wouldn't wait for Anne to discover that it was missing, I'd tell her. Of course it would have to be a lie. I'd say that I'd been given a hot tip by one of my friends. It was certain to win, but it hadn't. I'd been unlucky because it was pipped at the post by another horse. I'd then tell her how sorry I was, and that I would never do it again. If I could manage to, I'd even cry. She'd be angry, and for a few days my life would be hell, but eventually she'd forgive me, because that's what married people do, even when the spouse does something stupid.
Anne called me at six o'clock in the evening, to check that I was still coping OK without her. I was, and I was now almost back to normal. I was even contemplating having a beer or two while I watched the football.
The next day she was back home in the evening, just after five, and surprisingly, her Mother was with her. And she was carrying a suitcase. What was going on? Before I could ask, Anne spoke.
"Walt is away on business tomorrow, so Mother has come to stay with us," then, as an afterthought, she added, "I hope you don't mind."
I didn't, but it wouldn't matter if I did, because she was already here, and her large suitcase told me that it was for more than a couple of days.
Later on, while we ate together, I was told more. Walt was a Management Consultant, and he'd been asked, at short notice, by one of his clients to go to their Singapore office. Apparently, it was making a loss, and they needed him there to turn it around.
I asked, "So how long will he be away for?"
"At least for two weeks."
Now that was a coincidence, because the time limit on the bet was also two weeks. And considering how boastful I'd been, telling Simon how easy it would be, his suggestion of that duration had been generous. That got me thinking. I worked from home and my Mother-in-law was a lady of leisure. Walt, her partner for the last eight years, was wealthy, so she didn't need a job. During the day, while Anne was out, we would be spending a lot of time together. The perfect opportunity for something to happen between us. After giving it more thought, I made a decision. And now that I had, it was taking all of my self-control not to smile.
I was going to win the bet!
We'd been apart for a week, so both of us were eager to go to bed early. However, we had to stay up later than we wanted to, because Liza was here with us. It was almost ten o'clock before we got to our bedroom.
As soon as the door was closed, we were kissing, and my hands were on her tits. This was going to be a quick fuck. While she'd been away, I'd kept my hands off my cock, so my balls were full. And now I desperately wanted to empty them into her sweet pussy. And it was what she wanted as well, because before my fingers had even found her nipples, she stepped back, so that she could take her panties off.
She was now on all fours, and I was behind her, cock in hand, ready to position it at her opening. But first, I took the opportunity to admire the view. This was a pussy that never failed to excite me. I loved her large lips, they were a nice mouthful. And hidden under all those folds was a clit that was a nice size.
When I entered her, it was with a force and speed that took her breath away. And I didn't give her any time to recover. She was now being fucked hard, and I was using every bit of my big cock. On every stroke she was getting all of my eight inches.
"Fuck, I love your big cock. Make me come."
When I upped the pace, her moaning became louder, and I was now grunting. We'd become rutting animals.
The stroke that made her come was brutal, but it needed two more of the same before I reached it. Mine was a long satisfying one, and hers was equally impressive. When I'd finished spurting, she was coming down from her high. It hadn't taken us long, but it was what both of us had needed. After pulling out of her we cuddled, but only briefly. Within minutes we were both sound asleep.
I thought that I was the first one up, but I was wrong. Liza was already in the kitchen, and she was making breakfast.
"Coffee's made, help yourself."
After thanking her, I did.
"One egg or two?"
"Two please."
When it was ready she served me, and that's when I realized that she wasn't going to eat. She must have seen the surprise on my face, because I got an explanation for why she wasn't joining me.
"I've already had my breakfast. Just some toast. I need to watch my weight."
If it wasn't for the bet I wouldn't have said anything. But if I was eventually going to get to fuck her, I had to start somewhere. And now, because she had given me the opportunity to flatter her, this was the perfect time to start.
With a cheeky grin, I said, "You don't need to. You look OK to me."
