Ruth knew it was wrong, but she was forty two next week, and she wanted to do something daring and secret before she was too old to pull it off. The particular thing she wanted to do was seduce her son in-law, Simon, who she knew found her attractive but because he was married to her daughter, Kate, had to satisfy himself with admiring Ruth's well toned body. Ruth was a slim five feet six inches tall with short bobbed hair, which, when tucked behind her ears made her look much younger than her impending forty two years. She had never been one for sitting in the sun, and now reaped the benefit. Her skin was pale, but smooth and wrinkle free. She had a plan in mind for the seduction of her son in-law, but was waiting for the right moment. As luck would have it the moment arrived two days before her birthday one Saturday morning. Her daughter and husband had gone out to buy Ruth a birthday present, leaving her alone in the house with Simon for a couple of hours.
Simon stepped from the shower taking a towel from the heated rail when he heard his mother in-law call from the bedroom.
"Simon, can you give me a hand for just a second," Ruth called.
"Just a moment, I've only got my boxer shorts on," Simon called back.
"Oh don't worry about that," she replied, "It'll only take a second."
Simon walked down the corridor to his mother in-law's bedroom. Entering he saw Ruth standing in front of a full length mirror trying to zip up the back of her dress. It was a black ,sleeveless, and very figure hugging cocktail number with a turtle neck finishing just at knee level with a small split at the back. Ruth saw Simon in the reflection of the mirror, and stopped for a long moment. He stood in the doorway his semi-naked body lean and hard, his dark hair a tousled mess fresh from the shower. Ruth had always been attracted to her son in-law, and was delighted her daughter had married him two years earlier. Now she felt her stomach tighten, and her heart beat a little faster as she admired his athletic body.
"Would you be a honey and help me do up this dress," she asked, "I'm trying it on for the party next week."
"No problem," said Simon, stepping up behind Ruth.
She watched him in the mirror's reflection as he looked down to find the small zipper. Ruth knew he would get a glimpse of the black satin basque she was wearing beneath the dress.
"It's a shame to cover up such nice underwear, don't you think," Ruth said in an even tone. "Kate told me you bought her some very expensive lingerie last Christmas. Tell me, what colour did you buy for her." she asked, already knowing the answer.
"Black," said Simon, pulling the zipper up.
Ruth continued, "This isn't the kind of underwear I would normally wear outside the bedroom, if you get my drift, but it nips me in at the waist which helps this dress fit better."
Simon didn't know what to say to this remark so thought he better make his excuses and leave.
"Well if that's all," he said, turning to leave, "I'd better go and get dressed."
"Oh just stay a moment longer, and tell me what you think of the whole outfit," she said, pointing to a low wicker chair standing opposite the full length mirror. "Now, where are my shoes." Ruth bent over, deliberately keeping her legs straight to give Simon a good look at her firm peach shaped behind. As she did the material of the dress stretched a little tighter across her buttocks, allowing Simon to see the faint outline of a clasp, confirming ,what he already suspected, that she was wearing stockings and suspenders. Ruth selected a pair of black shoes with four inch spiked heels, severely pointed toes, and a small ankle strap.
Simon could feel an erection starting so he sat in the wicker chair to hide the increasing bulge.
Ruth put on the shoes. "I wouldn't like to walk very far in these," she said, "but they do look very sexy, don't you think?" pointing a foot towards Simon, and turning it side ways so he could appreciate the spiked heels.
"Very," was all Simon could say. His prick becoming harder by the second.
Ruth was well aware of Simon's growing erection, she was enjoying the effect she was having. "Now one more thing to complete the look," she said crossing the room to the dressing table. From a draw Ruth took a pair of black, full length satin gloves. Pulling them on she smoothed each one up her arm and over her elbow. Now the only part of her body that was exposed was the pale skin of her upper arms, and her slim shoulders. Ruth stood in front of the mirror turning this way and that admiring the fit of her dress, smoothing it down over her flat stomach. " Well what do you think?," she said, turning to Simon.
Watching his mother in-law dressing in such a provocative way had given Simon an erection so hard it ached. He crossed his legs, trying to conceal it.
Ruth turned to Simon looking directly at his crotch. "I can see my outfit has had the desired effect," she said with a small smile. Delighted that he was so aroused, Ruth pressed on.
Simon knew he'd been caught so gave up hiding his obvious arousal. He uncrossed his legs, his erection straining against his shorts.
Ruth was now standing directly in front of her son in-law who was still seated in the low wicker chair.
"Tell me," she said, "do you ever think of me when your jerking off?"
"Who says I do jerk off," a defiant note in his voice.
"Oh, come on," Ruth chided "all men do from time to time. So what's the answer. Do you ever think of me when your jerking off?"
"Well if I didn't, I certainly will now," he said with a small smile.
Ruth smiled back. "I feel rather responsible for your current discomfort. I think it only fair I should do something to help you," she said in a rather formal way, but with the smile still playing on her lips.
"What did you have in mind," said Simon.
"Some people," said Ruth, "get undressed for sex. I,on the other hand like to dress for sex. As you can see I'm dressed, and let me tell you, I'm as horny as hell." Without another word Ruth knelt in front of her son in-law, gently parting his knees. With a gloved hand she released the aching member. Pulling back the foreskin she revealed the purple glistening head of his turgid cock. Ruth lowered her head, parted her lips, engulfing his prick in the warm silky wetness of her mouth. Holding his rock hard prick in both hands she slowly began to suck and roll her tongue around its bulbous head. Simon lay back in the chair watching his mother in-law bring him to climax. Ruth, breathing only through her nose, never once parted her lips or allowed his cock to slip from her mouth. She could feel his prick twitch as Simon neared his orgasm. He tried to hold back but Ruth was doing too good a job. Suddenly he felt himself explode into her mouth. Ruth didn't miss a beat, she sucked harder and faster, swallowing once, twice, and finally a third time, Simon's hips lifted off the chair in an attempt to fuck his mother in-law's mouth. Spent, he collapsed back into the chair. Ruth finally released his cock in one long loving suck.. Simon leaned forward cupping Ruth's face in his hands, kissing her for the first time, their tongues entwined. He could taste his own salty cum on her lips.
"Unzip my dress," Ruth whispered.
Simon reached behind her and pulled down the zipper. Ruth stood up and took a pace backwards. With a small shrug of her shoulders the dress fell silently to the floor, and she stepped deftly out.
"Stunning," was all Simon could say.
Ruth stood before her son in-law in the black satin basque he had glimpsed earlier. But now Simon could see it in all its splendour. Its integral quarter cup bra allowed her erect nipples to be clearly seen, tailored to highlight Ruth's small waist it flared out slightly at her hips. Attached to the bottom were suspenders, holding up a pair of perfectly fitted black stockings. The high heel shoes, and long satin gloves completed a look.
"No panties?" Simon asked in mock surprise.
Ruth smiled, "Now you know my little secret." Framed by her stocking tops and suspenders was her beautifully smooth, clean shaven, pussy.
"Do you like what you see," she asked parting her legs slightly. Ruth could smell her own musky aroma drifting up from her engorged cunt. She desperately wanted to run a satin covered finger between its swollen lips, but resisted.
"Stunning," repeated Simon.
"Now," said Ruth in a stern voice, "I think you owe me a favour."
"I think I do," agreed Simon sitting forward in the low chair.
