I had discovered that my Mother-In-Law Rose had masterbated after she had accidentally felt my erection as I was comforting her after taking her home from a stay with my wife Cathy, me and our daughter over Christmas.  Rose's diary entry for that day revealed:-

"How exciting and naughty, it has been so long since I felt such a tingle.  In the evening I enjoyed such pleasure thinking about his body."

While I liked Rose and we got on well, I had not considered her a sexual fantasy, but now that all changed.

Living 20 miles away from us, I visited Rose every week or two, just call in, have a cup of tea, and chat for half an hour.  Rose was a widow and 20 years older than Cathy, very alike in personality and a little in looks.

As a young couple Rose and Brendan had been keen dancers, and even won the odd competition, with framed photos on her mantelpiece.

Next time I visited Rose two weeks later, I asked "Do you still have your dancing dresses?" .

Rose quickly replied "Only two of them; they hold wonderful memories for me, even if they are two sizes too small for me now."

I asked Rose if I could see those special dresses.

"If you have time, it will take me ten minutes to find and unwrap them."

"I'm not in a rush today, so please carry on."

Off she went up the stairs, and just five minutes passed when she brought the dresses down.  Both were full skirt dresses, slightly above the knee and with short sleeve tops, one in blue having a medium cleavage cut. the other in red with a split down to the waist front and back.

"They are lovely, Rose, it's a shame they are too small for you now, I know you would look stunning in either of them."

"Oh Gary, you flatterer."  But Rose had a beaming smile on her face.

I handled both the dresses, admiring the material, (and noting they were size 10).

I had finished my tea, and so I bade Rose farewell, with a kiss on the cheek.

 As soon as I had some time to myself after I got home, I searched the internet and found exactly what I wanted - a dress almost the same as her red dress, and a close match to the red colour.

I added it to my basket, in size 12, then added suspender belt, and stockings, and changed the delivery to Rose's address.  Click, and the order was done.

Next, on to Supermarket Groceries (I managed Rose's orders and deliveries for her), and to her usual grocery order, I added a pack of disposal razors and some shaving gel.

Came the day when her dress, sussies, and stockings were due for delivery, I texted Rose "Package arriving today for you, a fond gift from me. x".

My delivery notification arrived, and I spent the rest of the day waiting for my phone to bleep, but no such luck.

Early evening, I locked myself in the bathroom, and phoned Rose.

"Gary, the dress is wonderful and I tried it on, but it is rather tight, a size 14 would have been better." Rose announced.

"I thought you would look super sexy in a size 12, and it's not as if you would be wearing it out for an evening is it?"

"I suppose not."

"Be sure to wear it next time I call, promise me."  I chanced my arm.

"Oh, all right."

I went to bed that night smiling and horny.

The next morning Rose's grocery order was due, so I sent her the following text.  "I added two items to today's order, they are to help you feel super sexy in the red dress. x".

Unsurprisingly, Rose did not reply to my text, not then and not once the grocery order had been delivered.

Fate intervened at this point, and Cathy, me and my daughter were able to get away for the first time since the pandemic.  We managed a two week break in Wales on the coast.

This was refreshing after so long being locked down and after.  My thoughts never strayed far from thinking about Rose, and how and what she was doing.  I kept imagining her pleasuring herself and thinking about me, and I will admit to once or twice letting my thoughts stray while making love to Cathy.

Back home, and I was scheduled to visit Rose for the first time in a month; the day arrived and I sent the usual text telling her what time, etc.

Bleep "OK see you soon. X".

Mmm, was my luck in, or was Rose being polite and just friendly?

I had a poor day workwise, and needed something to cheer me up.

I arrived at Rose's, rang the doorbell to announce I had arrived, then immediately used my key to let myself in.

I entered the front room and there was Rose, standing  in the centre of the room wearing her new red dress, stockings and high heel shoes to match, and a big grin on her face.

"Hello Gary.  Long time no see.".

"Wow!" and I quickly put my arms round her, and kissed her on the cheek, her fragance so nice, her skin, all soft.  We stood together holding close.

I had to sit down.

"Give me a twirl then."  She did, around and again, her dress spinnng and lifting to reveal her stocking tops, and suspenders, but no further.

The dress fitted very tightly, and immediately I noticed she was not wearing a bra (I picked this dress because a bra would ruin the effect, so I chose well).

Rose set about making the usual tea and cake, and spent two or three minutes in the kitchen, before bringing the tray and setting it down on the coffee table.  This required her to bend over, and I could see down the front of that dress and admire her full breasts heaving under the material.

We sat and drank our tea, Rose asking about our holiday, and me gently enquiring how she was, and so on.

Tea finished and Rose stood.  "I'll go and change now, the dress is lovely, but I need to be a bit more comfy."

Off she went.

While she was gone, I felt the need to adjust my erection, and was standing, with my zip undone and my cock half our when Rose re-appeared at the front room door.

"Oh, Gary what have you got there?"

Rose was stood before me naked apart from suspender belt stockings and shoes, her pussy smooth as silk and wet for me to admire.
