Over the last few weeks, I'd begun a special relationship with my mother-in-law, a mixture of tenderness, submission and occasional humiliation...
After stealing a bra from her (see "My mother-in-law's bra"), I developed a - risky - strategy on New Year's Eve to finally get her to compromise with me.
A strategy explained in detail in the series "Under my MIL's dress", by the way.
But since that famous evening, I'd been feeling a certain slackness... It was indeed difficult to see each other, as her partner was often at home, while her daughter -forcedly- lived with me. Our respective work schedules left us no time to see each other elsewhere during the day...
Of course, we kept up furious & torrid exchanges via social networks... I've lost count of the scabrous photos & videos we exchanged, sometimes with a little token from me...
Going to work without a bra and without sweater on a summer's day, and taking a photo of her hardened little nipples just before she went to class... Make her wear a dress without panties while she's at work... Film herself taking off her bra in the bathroom at work... etc...
She was sometimes recalcitrant, but my little manipulation technique always worked well. I'd send her a photo or video of my over-inflated cock and Marie Christelle, as if bewitched, would do my bidding...
Before our little games, her sex life was at a complete standstill, and the fact that I was younger than she was - and that I got a hard-on sincerely watching her - gave her a boost, and after the sensual moments we'd spent together previously, she didn't want to fall back into that routine...
And there was a risk of routine. I still hadn't fucked her, due to a lack of an opportunity, and I had to find a solution very quickly to get back together with her, and fall back into my little manipulations.
It was an advert for a garden maintenance product that gave me an idea: in the promotional clip, a beautiful villa, complete with large garden and swimming pool, was featured.
Bingo! Go swimming with her! This would arouse little or no suspicion from our respective companions, and the prospect of checking her out in a swimsuit and playing with her gave me a hard-on just thinking about it.
So I proposed the idea. Summer was just around the corner. The high temperatures and the summer mood convinced her.
So we arranged to meet on Saturday the week of eight, at around 10 a.m., in the large pool parking lot.
I also told her that, given the weather, I'd be very grateful if she'd put on a skirt and wear something light.
To her surprise, I didn't ask her to forget her bra, simply because I had a few ideas for later, which I carefully kept to myself of course...
On the big day, I stepped out of my car onto the pool's gravel parking lot.
The parking lot was vast, as was the pool: a swimming pool, a more playful area with slides, rapids for sliding, sauna & jacuzzi area, wave pool...etc...
To my delight, there weren't many cars in the parking lot during the vacation season, so I didn't expect many people inside.
I spotted Marie Christelle standing by her car. To my delight, that day she was wearing a long pair of brown boots I didn't know she had, a green T-shirt with a wide collar, revealing a white bra strap, and a magnificent short leather skirt I'd given her as a present!
In my jeans, my cock pulsated slightly...
"Waow", I said, sincerely! "You're very beautiful, Marie Christelle" I declared, kissing her on the cheek. We were reluctantly unable to kiss as we would have liked, in public.
"Hi, my son-in-law," she smiled at me.... "I hesitated to put it on because I'm a really a bit too old to..."... I interrupted her with a sharp slap on the ass.
"She exclaimed in surprise. Then, looking around worriedly, she added: "Are you crazy? I interrupted her again by putting my hand on her bare shoulder, tasting the silky material of her bra strap.
"Sorry, but if you're bullshitting, I've got to let you know," I said, falsely stern.
"That skirt looks great on you," I asserted vigorously.
"It makes your ass all taut and sexy" I continued, pouting.
Then, taking advantage of the fact that we were partially hidden from view from the pool by her car, I grabbed her little hand and placed it on my already stiff cock:
"I'd love to bang you in it, doggy-style, while you're wearing it pantless", I whispered in a warm voice...
Marie Christelle quickly withdrew her hand, giving me a feverish look...
"Ooh n...no, don't arouse me before we go swimming" she tells me, trembling....
"It's not play to frustrate me like this...I want to stay focused on swimming today, come on!" she tells me as she walks away....
Inwardly, I was pleased to see that she was once again trying to keep control... Once again, this little morning was going to prove interesting...
After paying, leaving our shoes in the hall, we headed for the cabins.
Of course, we were supposed to change into individual cabins, but just as Marie Christelle was about to close the door to hers, I rushed in with her, closed the door and pressed her against the wall, my hand over her mouth to stifle her nascent protests...
I could see the surprise in her eyes, and also a little fear; she was probably wondering what I had in mind and whispered her fears to me: "But aren't you well? "What if someone sees us? Can you imagine the scandal? And... and the publicity? I'm losing my job, I'm losing my partner..." she began in panic...
I kissed her full on the lips. Then I put my hands on her shoulders.
I plunged my eyes into hers, speaking as softly as I could:
"Mmmh... I'd love to fuck you here, in this cabin, you know?"...
She gave me a faint smile, and I read in her eyes the anguish of being heard by someone and at he same time, tempted to finally copulate with me, guessing at the ardor I was going to put into the act...
"I want too so much," she whispered... "But let's go to a hotel or somewhere but not here, where everyone can hear us..." she explained, feverish and quite worried.
I decided to be cunning. I already had a little idea in mind...
"Listen", I began, "I'm going to need a little substitute, because if I don't, I'll be doomed to be stiff in my swimming trunks, flat against my cock"...
To prepare her for my request, I again placed her little hand against my cock, which was pulsating with desire... A technique I used every time with success, to pervert her and bend her will or her reasonableness... To my delight, she didn't withdraw her hand.
