There was some light coming in from the street, not a lot, but enough for me to see what she was doing. And what she was doing was mesmerising me, she was undressing. I couldn't take my eyes off her.
After slowly slipping both straps of her nightie from her shoulders, she stopped. When she removed her hands, I expected it to fall to her waist, but it was defying gravity by still covering her ample breasts. I took a step forward, so that when she was to pull it down, I'd have a clearer view. But she had a better idea.
When she flicked the switch, the light from the bedside lamp blinded me, and it took me a few seconds to refocus my eyes. I couldn't believe it, I was now seeing something that I thought that I would never see, my Mother-in-law's naked tits. And they were a thing of beauty.
I'd entered the spare bedroom because that's where my Sister-in-law was. We were going to fuck while Avril was asleep in the other room. However, after getting into bed with her, and then tenderly kissing the back of her neck, I'd realized that the woman in the bed wasn't Tina, it was Rose. I'd been horrified. If only I hadn't kissed her, then I might have been able to leave without waking her.
"You're in the wrong room."
That had made my blood run cold. In the morning she would tell her Daughter. I might get away with going into the wrong bedroom, but the kiss, when I should have known that it wasn't her, would be more difficult to explain. And my Wife was not a forgiving person. For days, perhaps even weeks, she would make my life a misery.
After getting over the shock of hearing her speak, I'd said, with sincerity, "Sorry, my mistake."
But would she believe me, or would she think that I'd done it deliberately? I'd turned to leave, but her response stopped me in my tracks. It wasn't what I had expected!
"Don't go."
I knew that it wasn't so that we could sit and talk, or hold hands and read the bible, so the sensible thing to do was to leave. She was fifty and I was thirty two. Both of us were old enough to know that what we were about to do was not a good idea, but that wasn't going to stop us doing it.
Apart from that brief kiss on her neck, I hadn't touched her body, but just looking at her exposed breasts was enough to make me hard. And she was already excited as well, because, without any attention from my fingers or mouth, her impressive nipples were already swollen.
I first met her ten years ago when I started dating Avril. Two years later she became my Mother-in-law. Our relationship has always been OK, but nothing special. I have friends who flirt with their Mother-in-law, but I've never done that with Rose, even when I've had too much to drink. On a scale of one to ten, for behaving improperly with her, it's always been a solid one. But now, like the strongman game at a funfair, the hammer has come down and the score is racing upwards towards ten!
As I took another step towards her, my heart was pounding in my chest. This time it wasn't to get a better view, it was so that I could touch her. But did I really want to do that? I was already fucking my Sister-in-law, so to now have my Mother-in-law would make my life even more complicated. But I swiftly dismissed any doubts. Yes, I did want to do it.
She was my Mother-in-law, therefore deserving of my respect, so I wasn't going to be rough with her. When my fingers made contact with her breast, it was with the lightest of pressure. It was as if I was handling a delicate object that needed to be treated with reverence. Her skin was soft and smooth, and that didn't surprise me. She was a woman that pampered herself, and she had the money for expensive treatments. Three times a week, for at least an hour, she exercised with her personal trainer. It would take you a long time to find a woman of her age that was in a better shape than she was. Like her two Daughters, she was a small woman with curves in all the right places, and because she had looked after herself, she still had men looking at her with lust in their eyes. And I was now one of them.
My friend Alex says, "She's one hot MILF," and I'd have to agree with him.
I was now playing with both her breasts, subtly caressing them. I could see the excitement in her face while I was doing it. And then when, without any warning, I touched her nipples for the first time, she uttered a low moan.
Both her Daughters have impressive nipples, they're long and thick, just how I like them. Hers were in the same league, and now, like I'd done with Avril's and Tina's, I was going to feast on them.
When I started pulling on them she moaned again, but this time a lot louder. It might even have been loud enough to wake up Avril.
"Don't worry she's taken her sleeping pills. I know, because she asked me to get them for her."
My face must have shown my concern, and I was even thinking about stopping, but now I knew that we could continue. With the medication that she was taking, only an earthquake would wake her up, and it would have to be at least a magnitude of eight point five on the Richter scale!
I'd pulled on her nipples and she'd liked it. But what else did she like? When I rolled them between my finger and thumb, she purred with pleasure. Good, like Avril and Tina, she had responsive nipples.
"Please will you suck them?"
That made me smile. As always, so polite, and the tone and inflection was as if she was asking me to help her with some chore.
"Andy, please will you help me take the shopping out of the car?"
I, of course, being the dutiful Son-in-law, always does what she asks, even when I really don't want to. However, what she was asking me to do now, was something that I was eager to do, and for as long as she wanted me to do it.
The first suck was tentative, and it wasn't what she wanted.
"Do it again, and this time harder and for longer."
She sounded like a school teacher correcting a pupil, and I wanted to laugh, but, with some difficulty, I managed to keep control. If I had laughed, then it would have got me into more trouble. Perhaps even a detention!
She was now getting what she wanted, her nipple being sucked vigorously, and she was showing her appreciation by moaning loudly. But what about me, was I doing it as a selfless act, purely for her pleasure? Don't be silly, I was enjoying it as much as she was, perhaps even more. Was there anything in life that was better than enjoying a plump nipple? I was about to say no, but then I remembered what was waiting for me. It was what she had between her slim elegant legs. Just thinking about that took my excitement to a higher level.
