"Dave? I can't hear, the line's bad."
"I'm here, Tan. What's up?"
"Oh that's better. I'm coming home!"
"When?"
"I'm flying out in two days. Be there in four. Can I come stay with you, little brother? I don't want to go to Brisbane and have mum and dad fawning over me again."
"Of course you can. I'll make up the bed. Oh Tanya, I can't wait. We're all so proud of you!"
Tanya was finishing her second tour in Afghanistan as an Army helicopter pilot. I knew the risks she took for our country, I was so proud of my big sister, and even more relieved that she'd be home safely.
And that was how my sister started living with me. I'm Dave, 24 years old, a little overweight since I had to stop playing football after a nasty motorbike accident. Tanya is two years older than me, the same height at six feet, but she's slim and athletic. We both have light brown hair, hers she used to colour with darker streaks and tie in a practical pony tail.
Those four days went quite quickly despite my longing to see her again. Then on the fourth morning she was there, on my doorstep in her Army greens and slouch hat, smiling and holding out her arms. We hugged, kissed cheeks, hugged again. I helped her get her kitbag inside. She still had those coloured streaks in her hair, I noticed her eye makeup, high cheeks, sweet lips, straight white teeth. All was as it should be, except...
"Are you limping?"
"Yeah, bro. Don't tell mum and dad yet, I caught some shrapnel from an IED that was outside the base. Think of it - the bloody thing was forty meters away and I was the only one hit! Swooping around like a maniac in my chopper getting shot at didn't do it, having a beer in the mess tent and I got hit!"
"Is it serious?"
"Nah, not really. But I'm not going back. I've got a posting here, instructing."
"Fabulous! I'm sorry you got hit, though."
"Yeah, and I'm sorry you came off your bike mate."
"Messed up my deadly-accurate kicking style."
"You never had one!" We laughed.
For a couple of hours we chatted, caught up with news. I was in awe of her. I'd done three years in the Army too, but never got deployed, so I was also a bit jealous of her. We knew some of the same soldiers, she told me about them. I made her lunch. We went outside and sat sipping cold beer on the porch.
"Oh, you got a spa installed?"
"Yeah. Helps relieve the ache in my leg. That's my excuse anyway."
"Cool! Let's get in."
"It'll be cold, hasn't been on since yesterday. Give it a couple of hours."
I turned the heater on. Tanya went to unpack. She didn't have much stuff, most was at the base, but I'd offered to let her live here permanently if she wanted, and she was going to get the rest of her stuff and move in soon.
By the time the spa had heated up, we were quite loose from drinking beer. I put some more in a big cooler and poured ice over them then placed the cooler beside the spa. Tanya took a shower, I was already in the spa. She came out in a thigh-length cotton wrap, bare legs visible under it. She threw it over a chair and stepped over the rim of the spa. She wore sports shorts and a t-shirt.
"Sorry mate, only things I could find."
"No problem."
She sat and the t-shirt immediately became transparent. She wore a thin pale-coloured bra, which showed through. "Thought that might happen, that's why I wore the bra."
"You don't go commando then?"
"Fuck no, not in front of you. Remember what happened last time?"
I did remember it and smiled at her joke. We were at the beach, about a year ago, just before she went overseas. We'd swam and were laying on towels in the sun. She asked if I'd be freaked out if she went topless, I said no thinking I'd be cool enough that my sister's tits wouldn't turn me on any more than the half-dozen pairs I'd already seen that day. As it turned out, I was wrong.
I tried not to look but, well, they weren't just tits. They were
her
tits. Hell, I'd watched them as they grew. And now they were round, firm C-cups and wet, the cool breeze made her nipples hard, and I had to tear my eyes away. Her eyes closed once she thought I was comfortable with it, and I looked at them once too often. My cock bulged in my shorts.
Tanya must have sensed something. Without opening her eyes, she said: "Are you gawping at my tits?"
"Um, not gawping, exactly."
She opened one eye suspiciously. I was sprung. She looked down at my obvious excitement then back into my embarrassed eyes.
"You gonna stop looking at my tits?" She was teasing so I played along.
"You gonna put 'em away?"
"If I have to. But if you start wanking that pole of yours I'm gonna beat you into a pulp."
I did manage to stop looking, and eventually my erection subsided although the memory of those fine breasts never did.
But now, here she was in my spa, teasing me about it all over again. I turned on the jets. Tanya closed her eyes and eased back until she was almost underwater, luxuriating in the massage of the steaming water.
After a couple of minutes in silence, she sat up and reached for her can. She emptied it and asked if I wanted another. I did, and she stood to get them for us. She only had to bend slightly to reach them but her wet shorts clung to her bum and I knew instantly that she was 'commando' under her shorts. In the two seconds I was looking, before I looked away again, I saw three things. One: Her arse was round, slim, and supple. Two: Her shorts were clinging into her pussy. And three: To my guilty delight I knew she was shaved smooth. All that was revealed to me by how the thin fabric stuck to her contours.
I doubted she knew what a show she'd given me. I closed my eyes to pretend I wasn't looking, she tapped my shoulder with the fresh cold beer and handed it to me.
As she sat back down her t-shirt billowed about in the water. She said: "I'm gonna take this off. It's too clingy." She peeled it over her head awkwardly, and while it covered her eyes I sneaked a peek at her chest. Her bra was one of those plain, sheer things, I saw now that it was flesh-coloured and cupped her ample bosom from below, presenting some cleavage to my eye, and then I had to look away again.
I had to admit to myself that I felt no guilt at gazing at my own sister's body like that. We'd spent little time together since we both joined up. I'd been out almost a year now, she joined six months before me. We'd never been posted to the same base, not even in training. In short, while we had been close growing up, we were not so close now. And that's my lame excuse for ogling my sister, and - dammit - getting a half-stiffy in the warm bubbling water.
We were chatting away about some Army stuff, and I must have been idly looking at her chest - just below the bubbling surface.
"Hey! Buster! Eyes up here, mate!"
"What?"
"You're trying to perve at my tits?"
"Was I? Oh, sorry."
"Haven't had much action recently?"
"Actually no. And truth is, you're the nearest thing to a girl I've had in this house in months."
"
Nearest thing
to a girl? What am
I
, a friggin' wombat?"
"Oh, I didn't mean that. I meant, um."
"Forget it. Drink your beer."
She was smirking at me, obviously enjoying my embarrassment. A minute later, she said: "Oh shit! The trouble with beer is it makes me wanna pee."
