Housemate's See-through Bikini

So this story is actually quite tame, there isn't anything sexual about it other than how I felt when this happened and the fact that it will be a permanent part of my mental wank-bank for months to come. But I've had a crush on my wife's best friend for years and I've always wanted to see her naked... and this is probably the closest I'll ever get.

It's absolutely pissing it down now, but a couple of weeks ago we had like five days of beautiful hot sunny weather. My wife Jess and our housemate Rachel (she is Jess's best friend) decided to spend the day in the garden sunbathing. I had some jobs to do, I wanted to build a compost bin out of some old bits of decking, and empty/clean/refill the hot tub, that sort of thing.

I set out the sun loungers for the girls, put the parasol up, then started to empty the hot tub. The girls came down, Jess was wearing her pink bikini which has a sort of skirt bit over her bikini bottoms, and Rachel was wearing a white bikini, it was almost indecent and didn't leave much to the imagination. Apparently it was new and Rachel had never worn it before... and I don't think she'll wear it again, as you'll soon find out! If you've read my previous stories about Rachel, you'll probably be bored of me describing her, but anyway, here we go again:

Rachel is 25 but she has a sort of innocent face that makes her look younger. She has shoulder-length light brown hair, a little bit curly, she has grey eyes. She normally wears contact lenses but she had an eye infection so she kept her contacts out when this story happened, and she was wearing glasses with geek-chic black frames which made her look even more cute than usual. She's very slim and her breasts are small, maybe even slightly smaller than Jess's (which is great, i love small breasts) and she has a nice shapely butt.

The girls kept calling me over to move the parasol, it's got a heavy base so it doesn't blow over, and the girls can't move it on their own. First they wanted to be in the sun, so I put the parasol down. They they got too hot and needed some shade, so I put it back up again. Then the sun had moved around so I had to move the parasol for them, then they wanted to catch some rays so i had to move it again.. The only good thing was that I was able to get right up close to Rachel, walk around her as I positioned the parasol, and get to see her from different angles. I think I could just about make out the swell of her nipples through her bikini, and as I walked around to the foot of her sun lounger, I made sure to check out her crotch, just in case there was a hint of cameltoe (but there wasn't).

Jess knew I was checking Rachel out, she was constantly rolling her eyes at me, lol, but it was jokingly.. she knows I have a crush on Rachel, we have a rule which is you can look but don't touch. So i was defnitely checking Rachel out, it's not often she's that scantily-clad! I was really hoping they'd go topless, occasionally Jess does when she's sunbathing, I thought that if Jess did then Rachel might do the same.... but no such luck.

Anyway, by midday they were getting real hot and wanted the shade, but the sun was right above us so there wasn't enough room for both of them to get sit in the shade of the parasol. I had emptied and cleaned the hot tub and was starting to fill it up again, and as a joke I sprayed Jess with the hose. She squealed, then said actually how refreshing it was, and that I could do it again when she'd put her towel and book away so they didn't get wet. I changed the setting on the hose attachment so it was a fine spray, and aimed it at Jess again, she squealed again and laughed, then said to Rachel she should try it. Rachel just raised an eyebrow as if to say WTF?! but I turned the hose on her anyway, just for a few seconds, and a couple of things happened. Just like Jess, she squealed like a skewered pig, and her bikini instantly went see-through.

I was stood at the foot of her sunlounger, staring at her - thank fuck I had my sunglasses on so she couldn't see my eyes fixed on her breasts. Her dark nipples were clearly showing through her bikini, honestly it was almost as though she wasn't wearing a top at all. Best of all, I guess the cold water had made her nipples hard, I could almost see them swelling before my eyes. Then I quickly glanced at Jess, she could also see Rachel's bikini was see-through but she didn't say anything, I think maybe she was checking Rachel out too (afterwards Jess told me she wasn't checking Rachel out, but she knew I was getting a kick out of seeing Rachel like that which was why she kept quiet).

Rachel hadn't noticed her bikini top was see-through, she just moaned at me and said I should have let her sit up first, now her lounger was all wet. I just stood there, not knowing what to say, I must of looked pretty lame, I probably had my mouth wide open, haha. I probably had a world-class boner noticeable through my shorts too, but all I can remember thinking right then was "wow, I can see Rachel's hard nipples".

Now, I've always loved breasts but I will take pussy over breasts anyday. But all this time, I'd been staring at Rachel's see-through bikini top without even considering anything else. It was only when Rachel tried to sit up in her lounger and slipped because of the water, and sort of flailed her legs to get her balance, then stood up, that I even considered looking at her crotch. And holy fuck, her bikini bottoms were just as see-through as her top.. I could see the dark hair of her bush, it was quite full but it stopped just above her pussy lips... and yes, i could clearly see the line of her lips through the wet material, and even (though this might have been my imagination) a tiny bit of her inner lips peeking out. Like her nipples, her pussy lips looked really dark compared to the rest of her skin. That image is engraved on my eyeballs, I can see it every time I close my eyes.

And that was it - she grabbed her towel and wrapped it around herself to dry off, then went inside to change. I looked at Jess and just said "wow", I was almost speechless. Jess laughed and asked me if I got a good eyeful, I said, "Oh yeah!" Jess said I'd better go indoors and sort myself out, otherwise she'd have to hose me down, this was when I noticed that my erection certainly was noticeable in my shorts. I went inside, up to our bedroom, took Jess's vibrator from her bedside table and pressed it to the head of my dick whilst I pictured Rachel's erect nipples and dark pussy lips....

I know this will probably sound a bit lame, it's not like I'm a horny teenager desperate for flashes of female nudity... but I've wanted to see this girl naked since I first clapped eyes on her, and this glimpse honestly feels like a gift from god! :)
