It all started with my dopey sister-in-law, Wendy. She's always been a little 'showy' - short skirts, tight little T-shirts and all that sort of thing - whereas I've always been too embarrassed to expose too much flesh (I don't even sunbathe topless when no-one can see me). My husband, Dave, always tries to encourage me and reckons that I've got an even better figure than the gorgeous little Wendy, but I guess I'm just too shy. Or at least ways I was.
Dave and his brother Tim (Wendy's husband) are twins and Wendy and I normally prepare them a special meal for their birthday and we were going to do the same this year until Wendy pointed out that it was their 30th and that she thought we should do something really special for them. She suggested we should dress up in really sexy gear to serve them their food and my first reaction was to run a mile. As I said, Wendy's quite daring and I'm not (or wasn't). I tried to dissuade her but we were sitting in her living room sipping wine, and by the time Tim came home and I left all I had managed to do was to persuade her that I was too embarrassed for anything really sexy but that I'd settle for short skirts and a skimpy top of some sort. That's the trouble with me mixing wine and Wendy - I end up in all sorts of trouble.
When the day arrived we went the boys to the pub while we prepared and then opened a bottle of wine to sip at while we were getting the meal ready. By the time we could leave the kitchen to get ourselves ready I was already a little tipsy and Wendy had spent the past hour and a half persuading me to go through with her little plan. I wasn't tipsy enough to let her get away with much but, despite my natural reticence, I was starting to feel a little bit excited (Dave, I knew, would enjoy this and I tried not to think of Tim's reaction).
We took another bottle of wine up to Wendy's bedroom and I found that she'd already spread out loads of skimpy clothes for us to try on. She had already said that she would find something for me to wear (I don't even own stuff like that let alone wear it!) and as we are similar sizes she reckoned that she'd be able to find something. I had been petrified before the wine, but now, as I say, I was getting a little excited and by the time I'd finished another glass of wine, I was giggling and staring at myself in the mirror wearing a tiny silk bra and panties. The bra barely covered my nipples and if they hadn't been so hard I doubt whether it would stay up!
Wendy was wearing a tiny g-string and nothing else and had somehow persuaded me to complete the outfit with a loose fitting mini-skirt and a low-cut blouse which was almost transparent. Oh well, I said - 'It is their birthday'. I was just about to step into the skirt, shivering a little with the thought of the boys eyes when they saw us (especially me!) when the front door opened.
'Perhaps we should just go down like this?' Wendy suggested making for the door.
I grabbed her, giggling, 'No way! It's bad enough as it is.'
'Well, it is their birthday,' Wendy mimicked me and we cracked up again.
I pulled her back to the bed and we finished dressing, Wendy calling out to the boys that we'd be down in a minute. I looked at the finished article in the mirror and a little, treacherous, thrill went through me. Even with the blouse on Tim and Dave had a clear view of the tiny bra which in itself was see-through enough to show a shadowy outline of my still-rigid nipples. The skirt barely covered my bum and when I turned sideways and bent over a little it rode up to show my tiny panties. I wondered if there was still time to back out of this but the wine and Wendy mixture had left me a little too excited. I glanced over at Wendy who was dressed almost the same as me but whereas my blouse was simply low-cut, hers gaped as she bent to admire her own view, and the tiny bra underneath was almost completely see-through. Not only would Dave get a kick out of seeing me like this, but also Wendy! Funnily enough, instead of that upsetting me a little it only served to excite me even more.
Nevertheless, Wendy still had to drag me forcibly out of the bedroom and downstairs. Outside the living room door Wendy stopped me and smiled at me, her face a little flushed. 'Well, it is their birthday,' she whispered, giggling quietly. I giggled back, even when she quickly undid the topmost button of her already revealing blouse and then followed it by doing the same to mine. I was about to protest but a firm hand in my back propelled both of us into the room.
'Hi, guys,' Wendy trilled.
Dave and Tim turned round a stared, their jaws dropping open. 'Wow!' Dave gasped and crossed over to me (giving an appreciate glance to Wendy as he came!).
'Happy birthday,' I told him, kissing his still gaping mouth.
'Definitely,' he hugged me hard and I could feel a distinct hard-on pressing into my groin. The feel of it excited me even more and all of a sudden this dressing up seemed like a great idea.
Wendy and I disentangled ourselves from our respective spouses and headed for the safety of the kitchen where we closed the door behind us and giggled together. 'I think we've pleased them,' Wendy commented, 'Did you see the fronts of their Chinos?'
'How could I miss,' I giggled (although I hadn't dared to look at Tim at all at that point).
Wendy, gasping a little quickly grabbed one of the prepared starters and headed for the dining room where the boys had been told to sit down. I followed quickly with the other before my nerve failed me. Not quickly enough though! Typical Wendy, instead of serving Tim she made straight for Dave and made a great show of bending over as she laid the dish on the table in front of him. His eyes, naturally enough gaped down the blouse at the tiny bra and Wendy's shapely breasts. Surprisingly (for me) this display - and Dave's reaction - gave me another thrill of excitement and I found myself at Tim's side before I realised it. 'Oh well, it is their birthday' I thought before copying Wendy and leaning down in front of Tim. It wasn't until I saw his napkin move on his lap, and noticed where his eyes were fixed before I realised that I was showing him more than I'd shown any other man apart from Dave. I glanced down my own blouse (along with Tim) and saw that the top halves of both nipples were visible - only their hardness keeping the bra in place at all. I straightened up quickly and looked over at Dave. He was staring backwards and forwards between me and Wendy and looked like the happiest husband in the World.
I shivered again and headed quickly back to the kitchen as Wendy wished them both 'bon appetite' with what I though was a little too much emphasis on the 'tit'.
I was gasping a little bit when we were both back in the steamy kitchen and had shut the door on four wide eyes and two gaping mouths.
'Think they're enjoying it so far?' Wendy asked.
'So far? How much further is there to go?' I giggled.
By way of answer Wendy undid the remaining buttons on her blouse and dropped it to the floor.
'We can't-' I began to protest, but she stopped me by saying that the boys had seen everything underneath already and then by unbuttoning my blouse. She pulled it off my shoulders and I stood there trying to make up my mind. Wendy's nipples were dark, hard and plainly visible through her bra and I realised that Dave must have seen exactly what I was seeing now. Again, perversely, it excited me more - especially when I remembered that Tim had seen a little of my own nipples. I looked down at the tiny bra I wore and made to adjust it so that they were completely covered, but Wendy stopped me.
'Tim's always said he'd like to see more of you, so don't disappoint him,' she laughed.
The wine had obviously done more than I thought because I just gaped at her and began to really enjoy this for the first time. 'Well,' I thought to myself, 'Dave and Tim seem to be enjoying this and Wendy obviously doesn't seem to mind And, of course, it was their birthday....' I giggled and shrugged, and Wendy laughed too, her flush deepening.
