Peters excitement at the thought of Stuart and Alison together had given rise to another plan, one that he would have to put into action straight away as Mandy was due to return home at the end of the week.
His Grandfather had been ill for the past year or so and, finding it very difficult to get around, had been confined mainly to the upstairs of his house. He had a nurse calling in on him every few days to check him over and ensure that he was taking care of himself. On top of this the old man had been very depressed, even contemplating suicide, so the nurse was also trying to keep an eye on his state of mind.
Peter had been there a few times when the nurse called and, although she was a very plain shapeless dreary looking middle-aged woman, he had noticed that, despite his depression, the old man appeared to get very excited when she examined him.
Peter never knew that a man like his Grandfather, now 81 years old, would ever be capable of raising a smile let alone the obvious erection that formed a tent in his pyjama trousers when she touched him. But then he figured that since his Grandmother had died some years ago and he was on his own it had to be quite an enjoyable experience for the poor old boy, even though her examination never took her anywhere near his excited organ.
The frumpy old nurse seemed to just ignore it, obviously understanding that these things happened and are perfectly natural. Peter however couldn't help noticing and could see how frustrating it must have been for him. He had even thought that maybe if the nurse gave him a little "help" with his problem then it might just go some way towards easing his depressed state.
Anyway he new that obviously that wasn't really possible and discounted the idea until now, when in a flash of inspiration he could suddenly see the possible opportunity to give him a once in a lifetime treat.
So with just a few days before Mandy was due to return home Peter pulled her to one side and told her he had one more "favour" to ask of her before she left. He explained very carefully what he wanted her to do.
He wanted her to pretend to be a nurse and pay a visit on his poor old Grandfather. He didn't want the old man knowing that it was all set up by him, instead he wanted her to act as if she was happy to help him out by showing him some special "kindness".
"I want you to make him happy," he told her, "and make sure you look good....you know what I mean."
Mandy knew exactly what he meant and wasn't happy at being asked to do yet something else. She knew, however, that she had no real choice and as she thought about it she soon began to realise that this may not be as bad as it seemed.
If the old man knew nothing about her, and Peter didn't want him knowing anything about his involvement then he wouldn't be in a position to demand anything and she would be in control. It would be up to her what she did or didn't do, the only real instruction she had was to make him think she was just a nurse and leave him satisfied, how hard can that be?
The week would soon be over and Mandy would be free of Peters demands, and so she agreed a little reluctantly to do what he asked of her.
Now Mandy needed a uniform and as luck would have it she had just the thing. Her mother had one of her white work uniforms that was a few sizes too small and she had altered it several months ago for Mandy to wear to a fancy dress party as a naughty nurse. As it turned out her father saw it and refused to allow her to wear it and so it got hung in the back of the cupboard where it remained to this day.
The following morning she went back home to collect it knowing full well everyone would be at work and so she wouldn't have to face any awkward questions. She found it hanging exactly where she had left it with a plastic cover over it to keep it clean.
On her return Peter was waiting to tell her that he had checked and the nurse wouldn't be calling on his Grandfather today so this would be an ideal opportunity. He gave her the keys to his house together with the address and sent her on her way.
"Don't forget," he told her as she was about to leave, "He deserves a special treat in his life, he doesn't have long left so do what you do best."
Mandy had decided it better to take her outfit in a bag and change at the old mans house. She knew he was confined to the upstairs so she would be able to get ready downstairs.
She couldn't help feeling a mixture of nervousness and excitement as she walked up the path to the front door. The house looked run down and in desperate need of some repair, and the garden was all overgrown with weeds. As she went to unlock the front door she noticed a rusty old bicycle propped up against the wall, and for just a moment she thought it looked familiar.
As she entered the house she was instantly hit by the damp musty smell of the place. It was untidy and there seemed to be junk everywhere and she found the whole place rather creepy. In the front room, aware that the old guy was just upstairs, she quietly opened her bag and changed into her "nurses" uniform.
On the wall was a dusty old mirror that she used to check herself out in as she changed her clothes. Halfway through she stopped and asked herself what the hell was she doing? Did she really need to do this? It took her a few minutes to argue the point with herself but the result was that she had come this far and what harm could it do, after all if she wasn't happy or became worried about anything she could just leave.
She looked herself over in the mirror and she liked what she saw. She knew how sexy she was, but this outfit was a real tease. It was lucky that she changed here because had she walked down the street looking like this she would have been mobbed by every man out there.
The crisp white one piece uniform was a little on the tight side, even around her slender and narrow waist. The buttons down the front however did an admirable job in holding it all together. The cut of the outfit was perfect for her figure, although tight it allowed enough breathing room for Mandy and her incredible breasts, instead of squashing them it held them perfectly showing off their impressive size and shape. She had decided not to wear a bra, the firmness of her tits meant she never really needed one, also the fit of the uniform seemed to do the job of holding them in place beautifully.
Mandy had decided to wear a nice pair of black seamed stockings held up by a black lace suspender belt with matching panties. Now the outfit had been shortened with the "naughty nurse" look in mind. Luckily it covered her stocking tops but didn't really leave much room for bending over without displaying the thick dark band that gave away the fact that they were indeed stockings she was wearing.
The uniform had buttons down the front that ran the full length from top to bottom. Being a little tight around the hips and ass she found it easier to undo the bottom two buttons to allow herself a little more freedom of movement.
She slipped on a pair of black four inch heels and as she twirled to look at herself in the mirror she was pleased with the way the uniform fitted nicely across her outwardly jutting ass.
"Gosh that is cheeky," the gorgeous 20 year old thought to herself, "now let's give this old man a bit of a thrill."
As she left the front room and crossed the hall to go upstairs she caught sight of something out of the corner of her eye, it was something that again looked familiar. Hanging on a hook was a filthy old coat, it was all torn and ragged and looked as if it belonged to an old tramp.
Just then a cold chill went down her spine, it couldn't be, could it? She was suddenly reminded of the old tramp that took advantage of her when she was 18. Could Peters Grandfather be that old tramp? With the bicycle outside and the coat hanging in the hall it was a distinct possibility.
"No, " she thought to herself, "no it couldn't be, what would be the odds?"
She put the idea out of her mind and went up the stairs, as she got to the landing she suddenly heard the toilet flush behind the door that was closed to her left. Without thinking she quickly went into the room opposite and hid behind the door, she didn't know why she did this it seemed to just be a natural reaction.
She spied through the partially open door and got a shock as the old man came out of the bathroom. She couldn't believe it, it was the old tramp, but it couldn't be, she had always assumed him to be homeless.
It was definitely him, she recognised him instantly, his image was so firmly stuck in her mind. The only difference was his beard, rather than the thick matted growth that she remembered, it had been cut back and was now just an untidy mess of grey stubble. He had obviously been ill as he now walked very slowly and with the aid of a stick. He took very small but quick shuffling steps as he crossed the landing to go back into his bedroom. As he went he seemed to constantly mutter to himself, his mouth hung open and he seemed to have such a sad expression across his old face.
All he wore was a grubby old pair of white underpants and nothing else, not a pretty sight for her to see as he shuffled off into his bedroom.
Mandy thought for a moment, this was a hell of a surprise and not something that she was expecting. She remembered the whole incident from her past so well and never thought she would ever see him again.
Although she felt she should leave she couldn't help thinking that maybe this was her chance to have a little fun on her own terms for once. The more she thought, the more the little devil inside her started coming to the fore.
She knew that he had no hold over her and he didn't look capable of forcing himself on her. On top of that she felt pretty sure that, as it had been two years since their very brief meeting, he almost certainly wouldn't recognise her. The only instruction Peter had given her was to make him happy, and so she thought that maybe she could do just that, but this time she would be in full control.
The cock teasing little minx smiled wickedly to herself as she undid the top few buttons of her uniform in order to show some of her incredible cleavage. She looked down at the swell of her 34FF bust proudly and whispered to herself, "right, let's have some fun."
As she entered the room she saw a high metal framed bed to her left with the old man laid out on it with no covers over himself.
