Sometimes he liked to get in the mood with a magazine or a book, maybe a video. The internet was good, too, because he could find words or pictures for more or less anything that worked for him. Best of all, though, was just to close his eyes and visualize. Sometimes remembering, sometimes imagining, maybe the two blurring into each other until he wasn't sure whether it was something he did in the past or something he would like to do in the future. But once he was focussed, he could let the hand and mind co-ordination work their daily magic.
That was what he wanted now: the images in his head, the slow build-up, the growing urgency, the explosive release. Maybe today, if it was very special, he would let it rest a while and then try for a repeat. He stripped, settled into his favourite chair, stretched out his legs and relaxed. He'd already been to the drawer, chosen a few of his favourites and draped them over the arm of his chair.
He decided to start with the white ones. A kind of cotton/nylon material. He didn't really know about fabrics. What he knew about these was the physical effect he could give himself with them. That and the recollection of how he came by them. She had told him she wasn't a virgin - who was at twenty-one, these days? - but he found her to be unbelievably naive. She liked it when he used his mouth on her but when he asked her to reciprocate she was disappointing. He put it down to inexperience and suggested she should use her hands instead.
That was better - and better still when he retrieved her knickers from the floor of the car and showed her how to wrap them round his shaft. Once she had found the rhythm, slowly easing the soft material up from the base almost to the tip and back again, his erection was quickly firm and responsive. In the darkness of the car, he could still see the white garment being manipulated by her pale fingers, and that was good. He was pleased they were white. After a while, though, she seemed to grow impatient, tightened her grip, speeded up until he was nearly cumming. Not what he wanted. All the evidence suggested she was still at a very early stage of her sexual development. That would mean a nice tight cunt. Cumming in her knickers could wait.
A back seat fuck was never easy and their first efforts to find a satisfactory position were clumsy. Concerned about losing his hardness, he persuaded her on to her knees so he could mount her from behind. That worked. He gave himself a few quick strokes with his right hand, tested her for wetness. Pleased with what he found, he guided himself into her. Maybe she wasn't quite as tight as he'd been expecting but it was good enough. By the fourth or fifth penetration, he was able to get his full length into her. Withdrawing, he found an angle of friction against the underside of his knob that was very exciting. He gripped her hips and pulled her on to him. Drove into her, pulled out, used his fingers to hold her open, then plunged in again. His balls swung through against her.
It couldn't last long like that, and he soon felt the spunk rising, demanding release. After two more thrusts he jerked himself free in the nick of time, sending a series of short spurts on to her buttocks. He was fairly sure she hadn't experienced an orgasm, or even come close to one, but she didn't seem concerned. All she did was ask him to wipe her clean; in the absence of any tissues, she told him to use her knickers. That was when he had the idea of asking her to let him keep them - as a souvenir "of a great fuck," he said. It hadn't been great but in her naivety she seemed impressed. He could have the knickers. He never saw her again, but his collection had begun.
Remembering that night in the car, he took care to control the way he used the knickers now. They were loosely rolled round his cock, his grip no more than enough to keep them in place, warm and comfortable. The tempo was slow and intermittent. If a particularly vivid image came into his mind - the moment when his knob first encountered her slippery cunt lips - he allowed himself a tentative squeeze, a brief physical reminder. But this was only the overture, the warm-up, the trial run. When it had achieved its object, and his shaft was hard, the purple head prominent, he put the white garment to one side.
Its replacement was red, lacy and insubstantial. No point trying to replicate the treat he gave himself with the white ones. These had a different purpose. He just needed to keep himself simmering while a new set of images took over. There was a good technique he had developed, holding the tiny red briefs in one hand, letting them brush across his balls, lightly, so lightly up his shaft, twirl round the knob with just minimal contact. When his cock began to twitch and jerk of its own volition, as though seeking closer, more intimate involvement, he would begin again. Tantalising himself, bringing the moment closer yet holding it at bay while the new images formed.
They belonged to the aftermath of an office party. She was a temp who had been with them only a couple of weeks and was destined to move on again shortly. Acting as second girl in the MD's office had kept her aloof from most of the staff. The grapevine said Penny was treading water until her fiancΓ© came back from a job overseas and married her. When he found himself sitting next to her at dinner she proved to be unexpectedly good company, easy to talk to and not as superior as the office gossip had suggested. Fortunately, the Chief Accountant, the Company bore, was on her other side so it was easy to monopolise her.
The year in the City had been good and the Company hadn't stinted on the party. At first, he had filled and refilled Penny's wine glass as a matter of courtesy but it wasn't long before he began to wonder if alcohol wasn't making her just a little susceptible. It needed only a few carefully loaded questions about her absent other half to make him think the signals coming back might be favourable. He knew he wasn't mistaken when she put her hand on his thigh under the table. For confirmation, he excused himself for leaning across her to reach a wine bottle and used the movement to brush against a substantial right breast. Far from recoiling, she moved against him while giving his thigh a squeeze.
Some watchful manoeuvring when the party broke up eventually allowed him to offer her a lift without attracting unwanted attention. Penny said she had intended to take a taxi but was happy to take up his offer. In the car, she didn't hesitate. Hardly had they set off before she said, "I think we both know what's going to happen, and I think you should know it's what I want, too. There's no point pretending - Andrew has been away for nearly three months." She let that sink in for a moment, then went on, "Three months and no sex. Not good for me. I need sex. You've no wedding ring so I take it you're not married?"
"No."
