*****
At age 38, Pauline knew she was too young to have a teenage son and way too young to be a widow.
Her son Ryan, now 18, was keen to join the army, and had been in the cadets since early high school. He was tall, strong, and very fit having played football since under-7s.
But he had become moody of late, and Pauline thought she knew the reason. She guessed it was simple sexual frustration, since Ryan had not had a steady girlfriend.
Ryan was at football training and Pauline liked having the house to herself. She knew she was very pretty. Of medium height, she had a classic hour-glass figure. Breasts the size of grapefruit, rounded hips and a slight paunch. No bony hips to grind on, just all woman.
Her black hair reached down to the bottom of her shoulder blades and was usually in a pony-tail for convenience, but when she let it free it shone around her square shoulders like a gossamer cape.
She was proud of her breasts, her legs and her pretty face, but most of all she was proud of her bum. There were girls of eighteen who would need a gym to get a tight butt with such perfect curves. Actresses worked hard to get what Pauline had naturally.
Consequently, if she was in the mood to show it off, she wore tight skirts and dresses. Her favourite was the long blue full-length formal number with the slit from ankle to upper thigh which sent her dates mad. It framed her shapely legs, it emphasised her fantastic arse, and the thin straps enabled her to showed deep cleavage with push-up support that turned heads often, earning many a man a slap from his date as she walked by.
She had it on now, even though she wasn't going anywhere. She had a date in a couple of days, a guy she was very keen on. They'd been out a few times, this time she was going to knock his socks off with how she looked. But she was worried she might not fit into it, thinking she had put on a kilo or two.
Her walk-in robe had mirrors on three sides. She liked what she saw in all of them.
"If Dan doesn't fancy me in this, I'll know he's gay!"
Smiling at herself in the mirrors, she tried to take it off but the zip stuck frustratingly just at the point where it was hardest to grasp from above or below, despite her contortions to reach it. She gave up and went to pour a long gin and tonic. Ryan would soon be home and he'd help her.
Two hours and four more G&Ts later, Ryan still wasn't home. He sometimes stayed on to hang out after training, but not usually on Mondays because he had an early start at work on Tuesdays.
Pauline had put some slinky music on and was dancing about sexily, her sixth drink in her hand. She got lost in the music, in the dance and in a slight tingly feeling she often got in this dress. It had been her man-trap outfit for a while and she thought of it as her ticket to sex.
Ryan had let himself in and dropped his sports bag in the hall without her noticing. He stood and watched her gyrating her hips to the music, her free hand caressing her thigh, side and breast like some pop music goddess.
"Hi mom. What are you doing?"
"Oh baby. Hah hah. I didn't hear you come in. I, um, well..."
"Why are you dressed up? Have you been out?"
"No, I was making sure I still fit into it. I need it on Saturday. But the zip got stuck. I'm pretty hot in it, don't you think?"
"Mom!"
"Oh come on. A girl likes to be told when she's looking sexy!"
"By her son? Are you drunk mom?"
"Maybe. A bit tipsy. Sorry baby. If I embarrassed you. Am I though? A bit?"
"I don't think I'm the one you should be asking."
She giggled. The gin and tonics were going to her head and she suddenly enjoyed the discomfort she was giving a young man, and Ryan being her son just meant she could tease and nothing would come of it. She thought. So she resumed her dance-gyrate and ambled towards him, humming the tune as she went, and looking into his eyes with a wicked glint.
He wasn't impressed. "Stoppit mom." Then he stormed off.
Pauline giggled at her own boldness and took another draught from the tall glass. Realising it was then almost empty, she drained the last sip and mixed another.
She heard Ryan in the shower and started dancing again, smiling as she remembered Ryan's blushes. Some minutes later, buzzing from the drinks, she had two thoughts. First, Ryan always showered in the locker room after training, especially if he was going to hang out. Second, she was still trapped in that dress.
What if she'd made her son horny and he'd gone to have a cold shower? She giggled at the thought, then a pang of guilt overcame her.
"Wrong, Pauline. That's wrong for you to be thinking like that. And I still need him to help me out of this dress."
So she went upstairs, knocked on his bedroom door.
"Ryan? Baby? I'm sorry. A bit tipsy. Baby I need you to help me get this zipper unstuck."
She heard shuffling from inside the room.
"Ryan?"
The door swung open abruptly and he stood there wrapped in a towel. Not for the first time Pauline admired the muscular frame she'd created in her womb. She smiled at him.
"The zip's stuck..."
She turned around, and Ryan reached up to it and tugged firmly. It worked. The zip went down easily to it's end, just below where the crack of her arse started. Pauline never wore a bra with this dress, so she had to hold the straps over her shoulders so it didn't fall.
"Thanks son. 'Night."
"G'night. And mom?"
"Yeah baby?"
"You are hot in that dress."
"Oh thanks baby!"
She stepped back into the room to give him a peck on the cheek, still holding the straps of her dress in both hands. Being a bit tipsy, her kiss was clumsy and she planted it straight on his lips.
"Ooh, sorry! Hah!"
She tried to stroke his cheek forgetting the hand was holding the dress over her breasts. It duly fell away and her clumsy attempts to keep them covered failed. In a last attempt at modesty she put her hands over her breasts, and the dress fell to her waist. In an agony of slowed seconds, she was aware it was gradually falling lower, peeling itself over her hips. Despite it hugging her figure she had no panties on and she could not risk letting it fall. As she turned away from her son's amazed gaze, simultaneously trying desperately to cover her breasts with one arm while holding the dress to her waist with her other hand, she tripped on the hem and stumbled sideways into Ryan, who instictively grabbed her to stop her falling. Her instincts took over as well, as both arms stretched out to break her fall with the inevitable result that she fell into her son's strong arms with bare breasts and the dress falling away altogether.
She cursed and kicked at the dress to untangle it from her feet, then standing she put a hand on Ryan's shoulder for balance.
Pauline bent to pick up the dress, intending to cover herself with it.
Ryan had been aroused since he'd walked in to see his pretty mother in her gorgeous dress slinkily stroking her breasts and gyrating to sensuous tunes. He'd gone to the shower intending to masturbate but despite his aching need for release he admonished himself for having horny thoughts about his own mother.
