Matt and Kylie had only been out of the pool for about fifteen minutes when Lucy appeared from her room.
It had at least given them time to get dressed; Kylie in a dry bikini, Matt in board shorts. Surprisingly Lucy came out in a new bikini top -- a pink version of the tiny black one Kylie had donated to the cause of her sexual education -- and a pair of very brief, very tight fitting, gym shorts, the pink tie strings of her bikini pants underneath hanging over the waistband.
It might have been their wet hair, or maybe the noise they made, but it was clear the Lucy was well aware of the fucking that was happening in her absence and that it was in the pool. As to whether she was put out by the knowledge, that was a different matter.
But one thing she did put on the table over breakfast was that Matt should sleep with her at least every third night. And everyone knew what that really meant at this early stage of the developing relationships, was that Matt would be having sex with her at least that often. Because that was how it was working. There was plenty of other sex happening too; but 'sleeping with' definitely meant fucking.
None of which would have been surprising if Lucy hadn't been a 30 year old virgin until two weeks ago; with everyone assuming she was asexual.
So it was undeniably the case that progress had been made in her sex education, even if her being on the spectrum left many awkward issues still to be dealt with; not the least of which being her aversion to external physical contact.
That Sunday played out normally enough. The three of them spent the day at the beach and Kylie made sure she got a good fucking as she and Matt retired together for bed that night. And since mundane matters such as having to go to work tended to moderate what happens during the week, it was Tuesday night, as Matt retired into bed with Lucy, before what might be called anything out of the ordinary occurred.
On the way home from work that day Matt had made a point of dropping into the storage unit where his life possessions were, to retrieve the 'sex pillow' his first live in girlfriend had made him buy. For the uneducated in such matters, a sex pillow is a triangular shaped (often inflatable) pillow placed under the females butt to offer, shall we say, a better presentation.
It wasn't that Matt didn't consider it might be useful with both the girls, but the need to have sex with Lucy while minimising skin on skin contact made it very difficult for Matt to get the right angle in the missionary position to stimulate her.
It might have been a bit presumptuous of Matt to assume that Lucy would want sex just because they were bedding down together, but the way she had insisted on having him sleep with her at least one night in three made it very clear she was looking for more than night time companionship.
Even so, this would be the first time Lucy would have penetrative sex without any alcohol in her system, so Matt wasn't approaching it with any preconceived notions of how it would play out.
As he returned from the shower and hung his wet towel on the back of the chair to climb naked into bed, he found Lucy lying on her back, uncovered except for a tiny pair of string sided panties; her normal style of undies and now-days her usual sleeping clothes [compared with what she wore before her sex education started of some fairly full coverage PJ's].
The blackout blinds were down, but the light still on; a pattern that had started early in her education at a time Matt was concerned her extreme modesty might have made her only want to have sex in a fully blacked out room.
Matt well understood that Lucy had to lead in whatever would happen. While she was aware of the sex pillow, Matt made it clear it wasn't there as a matter of presuming what would happen, simply a preparation for the possible.
But Matt didn't even have to ask what she wanted. From the outset, he'd been instructed fairly quickly by Lucy what the plan for any engagement was and this night was no different, even if the request caught him by surprise...
"Would you start by just playing with and sucking my nipples? Nothing more."
There was method to Lucy's strange request, even if Matt wasn't aware of it. Lucy had been surprised how sensitive her nipples were to stimulation and how powerful their effect was. Being of the nature she was, she'd researched the matter online and discovered that there was a wide range of possible reactions to nipple stimulation; from hating any stimulation at all to it being capable of giving you an orgasm without any other stimulation.
Consistent with her carefully curated approach to her life, she wanted to see if she was in the 'give her an orgasm' category.
Matt simply knew he had to comply.
It was not an unpleasant task he'd been set. Lucy's breasts -- like Kylie's -- had always been the focus of some, you could even call it obsession, on his part. As breasts went, they were certainly in the top tier from the point of view of male admiration.
A 'C' cup (or so Matt guessed), they were large on her small frame without in any way looking pendulous or crowding her chest to the point of losing the individuality of each one. With their perkiness, they were well 'lifted and separated' in the words of the old bra add, without requiring any assistance to achieve that.
When she stood they had this beautiful 'ski jump' shape; projecting confidently down to a well-defined point at the end without the underside of the breast sagging. The ski jump shape was less defined as she lay on her back, but was still there just the same.
More importantly -- visually anyway -- was the fact the point was still cleanly defined. Because at the point lay the most sensuous, sexually charged nipples Matt had ever seen.
The areola was a glorious brown colour, a little bigger than those of his previous girlfriends, but in a positive sort of way. Nowhere near the territory of being so big as to detract from, rather than enhancing, the perfection of her breasts. What he'd never seen before in another woman -- now except for Kylie who shared her sister's features - was the way her areola puffed up when stimulated, forming a low rise mushroom shaped head from which her nipple then projected. And the nipple itself seemed to project further, and have a slightly bigger diameter than he'd seen before.
The result was that you could almost fill your mouth with it; holding the swollen areola or even the tip of the breast, between your lips while your tongue pinned the top of the nipple to the roof of your mouth as it flicked against it.
With a wet bikini top plastered to it, it was almost impossible for any male to take their eyes off it. Exposed, they were almost irresistible.
