A Sisters' Ploy Ch. 09

At work the following Friday Matt found himself contemplating the fact that this would be the night he would spend in Lucy’s bed instead of Kylie’s.

The one night in three that Lucy demanded in their polygamous relationship.

Lucy had proved to be full of surprises. Matt, and Lucy’s sister, Kylie, had long since deduced that Lucy was probably on the spectrum and had serious sensory problems with physical contact with other persons. And guessed that she was probably asexual; having, at 30 years of age, admitted to never having been on a date, let alone been intimate with another person.

As a long time and trusted friend of hers, and currently without a partner, Matt had agreed to move in with Lucy and Kylie to, for want of a better way of putting it, give Lucy a sex education. It was assumed it would be a long and sexually frustrating process for Matt because it was assumed that most of the time Lucy would cut the process short and the essence of the trust was that Matt would take heed of her instructions.

Since Kylie had long had a crush on Matt, the deal had been that Kylie would see to Matt’s sexual frustration by meeting his sexual needs in a sort of polygamous relationship.

Since both sisters were stunningly attractive, it was definitely not a burden on Matt, even if, looking back in retrospect, the whole idea might seem rather strange.

But his starting assumption that it was a forlorn hope that Lucy wouldn’t be able to engage in a fully sexual relationship was quickly displaced. Yes, she had serious sensory issues, and they had to be worked through slowly. But it turned out she soon learned to crave the pleasure she found in sex, even if it had to be delivered to her with minimal contact with her non erogenous zones.

Matt could see that Lucy, in the carefully planned way that was typical of her, was working towards addressing those sensory issues too. Her discovery – weird though it was — that she had no trouble with contact with her erogenous zones, including her nipples, and that she liked fondling Matt’s, in the form of his cock, had left an avenue for pre and post sex physical interaction.

Now, a night spent in Lucy’s bed meant having sex with her. That’s how it worked, even if it wasn’t the only sex they had. But more recently it also meant Lucy would spend the night with her hands wrapped around his cock and his hands on her breast; a substitute for cuddling up. All very well except it left Matt feeling incredibly randy in the morning.

On two previous occasions Kylie had come to his rescue — or is that cum to his rescue — with morning sex. But now Lucy had declared she wanted to be the recipient of that, even though it meant Matt touching her up in her sleep.

And that is what was praying on Matt’s mind. Not in erotic anticipation, more as a concern. Until now, every step of Lucy’s progress had been carefully planned and supervised by her; Matt simply following instructions to ensure he didn’t overstep any boundaries.

Now he had an instruction to take an action while she slept; to finger, tweak and even fuck her in her sleeping state when he woke up randy in the morning. It might sound all very nice, but there were aspects of it that filled Matt with fear.

When he got home that afternoon, he found both girls already home and changed into their bikinis and sitting out by the pool; more or less the standard procedure for this time of year. Greeting them, he slipped into Kylie’s room where his gear was and changed into swimmers himself before checking on the ingredients for the dinner he was preparing that night.

Then he joined the girls by the pool.

The small round, poolside table was flanked by two Ottoman chairs. The chairs, big and comfortable enough for one person, two could only fit on a chair by being in intimately close contact. As was his habit because of Lucy’s sensory issues, he sat next to Kylie. It meant his thigh and flank were in full length contact with hers and, as she always did, she put her hand on his upper thigh and he put his around her back.

With both of them near naked, the inevitable result was Matt found himself partly aroused; something that was very obvious in the swim briefs he had on.

The girls had been drinking water as they chatted there, and Matt had brought a glass out with him too. But soon after he sat down, Lucy stood up…

“I’ll be back in a sec.”

It was impossible not to watch as Lucy, with her cute butt framed by a small bikini, sashayed towards the door leading into the kitchen. She returned a few moments later with a bottle of white wine and three glasses, setting them out on the table and then bent over to generously fill them as Matt watched her breasts dangle over the table.

This was not a very common indulgence. They might occasionally indulge in a glass of wine over dinner — especially on a hot day — but the glasses Lucy poured were much fuller than they normally would be.

It mattered because, while the group had found that a glass of wine did help Lucy overcome some inhibitions in the early days of her sex education, more recently they’d done without it. But on one occasion when she’d got really drunk, all her inhibitions and sensory problems had disappeared. Everyone recognised that was not a healthy way of regularly preparing her for sex, however much Lucy had enjoyed it. It was possible that, as an occasional ice breaker, it had a role, and Matt wondered if Lucy had decided to give it a go that night.

The speed with which she downed the first glass — on an empty stomach too — and refilled her glass, suggested that might be the case.

Matt was sipping his wine at a slower pace and, as he got up to prepare dinner, took the still half full glass with him. Dinner was a bit of a slow cook hot pot, so his main job at this time was cutting everything up and getting it into the pot and into the oven.

He hadn’t been working at it for long when he was joined by Lucy, carrying a glass which was already half empty from the second fill. Asking what he was planning for diner, she leaned seductively across the bench where he was cutting the chicken pieces; clearly bring her breasts within his field of vision.

Already she was slightly slurring her words. The one positive was that Lucy was a cheap drunk; at least in the sense it didn’t take much to get her inebriated. It was also clear she was quite aroused. It was a warm, even hot, night, and her nipples stood proud in her thin, tiny bikini top like a pair of volcanic cones.

As they talked, she kept sipping at her wine until the glass was again empty. Matt thought at least the slipping was better than the veritable sculling she did with the first glass. But as she finished it, she held it up to the light to examine its lack of content and indicated…

“Well, I’d better go back and keep Kylie company.”

It was about ten minutes later that Matt had completed his task and returned to the girls where they sat by the pool. As he approached the table, Lucy moved across on her Ottoman and patted the space on it that she’d made, indicating he should sit there.

That was not normal.

Normally Lucy’s sensory issues would not let her tolerate such close contact. Matt noted she now had a half empty third glass, so it was clear she was deliberately drinking herself into a less inhibited state. Matt didn’t feel as though he could disappoint her, so sat alongside her; deliberately sitting as close to her as he would with Kylie — maybe even a bit closer as there was almost an overlap of their bodies.

Lucy followed Kylie’s lead of putting a hand on Matt’s upper thigh, leaning over him so that she was almost resting her elbow in his crotch. Deciding that he should completely play Lucy’s game, Matt put his arm around her back, drawing her closer in to him.

It still caught Matt by surprise when Lucy half turned across his body, put an arm around his shoulder and passionately French kissed him, resting on — almost swooning into – the arm that he brought around to support her. Really the only previous time she’d done anything like that was when she was really drunk. At the same time she brought her other hand to his cock and started fondling it through his swimmers, producing a predictable result.

Kylie could do little more than watch her sister do a fairly full on PDA. This Lucy was a completely different one from the one she’d grown up with. She also watched with some fascination as Matt’s cock swelled and extended in Lucy’s hand until Lucy had produced a full on erection sheathed by Matt’s swimwear. It wasn’t that she hadn’t done that to Matt many, many times, it was just a different perspective seeing her previously assumed asexual sister do it and a certain fascination from watching it happen from a distance.

The process of the male appendage growing had always had a certain visual interest for her. But when it was her causing the growing, her opportunities to take a stand back look at it were limited.

Now she had the full show; the initial filling out of the bulge in his swimwear, the transformation of it into a more pole like shape as it straightened out, the vertical extension of it up his stomach, severely stretching the spandex material of his swimwear until it projected well over the waistband and nearly up to his navel, the further inflation of the bell as Lucy’s jerking of him caused it to surge and the first seeping through of pre-cum to form a puddle of the stuff on the top of it, all as her sister became increasingly impassioned in her pashing of Matt.

Lucy’s passions were pushing Matt further and further backward over the Ottoman until he was forced to drop a hand to the tiles, fortunately warmed by the afternoon sun, to support himself, Lucy nearly on top of him. Eventually it became too much. Matt brought Lucy’s body across him and eased her onto the tile surround of the pool, his body, tightly embraced in Lucy’s arms following on top of her.

Lucy passionately squirmed and dry humped him from underneath Matt until she forced her hand between their bodies, pulled aside the gusset of her swimwear, exposed Matt’s cock and brought him into her body.
