After an afternoon in the sun beside the hotel pool, during which my sister and I had sampled just about every cocktail known to the bartender, we were left to our own devices while mum and dad went to visit some old friends an hour up the coast.
Janet was four years older -- 23 -- and had briefly been married to a jerk with a gambling problem. Janet divorced him after only two years so she didn't lose her half of what little they had left. This holiday to the Gulf Coast was the family's "welcome back".
We were in our parents' suite because it had a better minibar and a spa bath. We each had a 'cabin' which was really a motel room with a bed and a kitchenette but we shared bathrooms with two other cabins, so we usually showered in this room.
Janet came out of the shower with a towel wrapped around her, so I went in for my turn.
When I came out, Janet was still wrapped in the towel, sitting on the bed drying her long brown hair with another towel.
"Hey towel-hog! I get this wet half-size rag and you get both the big dry fluffy numbers! What gives?"
"I'm just smarter than you. And quicker."
"Yeah right. If you're so smart you'd have made sure your arse was covered by that towel!" It was, but she had to be sure. She spun on the bed and in doing so actually ripped open the knot over her tits and they flung free. Beautiful. They were awesome, easily C cups, if not D. They were round and firm, with ruby-pink nipples poking out towards me. I teased: "Oops! Serves you right for pinching the last dry towel!"
"You pervert!" She said as she refastened the knot to hide her perfection from my gaze. "Did you enjoy perving at your sister's tits?"
"Well, I'd be a liar if I said no..."
"Well I hope you got a good look. Now get some clothes on before you fall out of that handkerchief you've got around your waist."
I hadn't noticed how loose the flimsy knot had been. I'd just got turned around when the thing gave way and I exited the room with my bum out and the sound of my sister's laughter following me to the bathroom.
I put on a simple pair of loose shorts and nothing else. We were in the tropics and even now, just before dusk, it was very warm. I replayed the image of my sister's tits in my mind and got trunky. My inner voice said:
Wow! Those fucking tits! I'm getting hard over my own sister's tits!
I was a virgin. Sure I'd had a couple of crazy fumbles and a hand job with Jackie Bennett but I'd jizzed on her skirt and she got pissed off and dumped me.
Back in the suite's bedroom, which was also the lounge and kitchen, Janet was in just t-shirt and knickers. She was walking away from where I stood and she bent low to get something from the minibar, treating me to a great view of her fine round arse cupped in tight white knickers. They were so tight that I could clearly see her slit for those brief seconds. I made a noise to announce my presence. A second passed. I stared. Then she produced two beers from the minibar and took the four steps over to me and handed me one. I took the beer and noted it was one of the ones we'd sneaked in that morning -- no point paying top dollar for minibar booze.
"What shall we do?" I said.
"How about 'truth or dare?'"
"Jesus Janet, we haven't played that since..."
"...And I remember that time well. You lost and got all upset."
"I 'lost' because you cheated and dared me to sneak into mum's room and pinch her vibrator and I wouldn't because at the time -- if you recall -- she was actually using it!"
Janet giggled and clapped her hands: "You
do
remember! So. You game?"
"Maybe. What are the boundaries?"
"Usual ones. Truth has to be real truth and dare has to be possible and not gross. In or out? I can always go back to the pool and pick up boys!"
Since Janet had moved back with us I'd become obsessed with her body. She'd spent much of this holiday in a wet bikini that had me constantly trying to sneak peeks. I didn't want her to leave this room now, I wanted more flashes of the delight between her thighs and I
really
wanted her to laugh some more. Because of what it did to her pointy, braless tits in that cotton t-shirt. She was sitting on the bed opposite me, I was in the comfy chair about two metres away.
"I'm in, and I'm first. Truth: How old were you when you had your first tongue-kiss?"
"Fourteen. Truth: Have you ever
had
a tongue-kiss?" She laughed at her tease; her tits jiggled.
"Yes. Dare. Drink the rest of that beer." She did. Plan worked. She went to get another one and again I watched her arse walk to the fridge and leered at it as she bent over. She came back.
"Truth: Did you did that so you could look at my arse?"
Fuck!
I wasn't going to lose that easily.
"Yes. Truth: You knew I was looking didn't you?"
"Yes. Truth: You're a pervy little nerd who's been spying on his sister's hot bod for days, aren't you?"
Damn, she'd noticed. This game was going somewhere fast and I wanted more. Well, she was smiling and teasing, so why not go for broke?
"Yes. Yes I have. OK Dare: Show me again."
"Oh I walked into that one didn't I? OK, here you go ya pervert!"
Janet bent right over just a metre away from my nose. Her panties were up in her arse-crack and her pussy lips were so visible that I instantly knew she was shaved. She slapped her butt-cheek with one hand and sat back down. She giggled. She caught me looking at her tits, and said: "Oh, little Mikey. You really are a sneak aren't you?"
"Was that your turn?"
"No it was not." She bit one side of her lower lip before she said: "Dare: Show me your cock."
The evening heat suddenly intensified. She wasn't joking, I could see it in her eyes. I went for it. I stood, pulled the shorts elastic forwards, grabbed my half-erection and pulled it out. I cupped my balls and presented the whole package for her. I let her get a good eyeful before I put it away.
"Oh wow Mikey! I was sure you'd say no and I'd win as usual!"
"Not so easy big sister! OK: Truth: Did you like my cock?"
Janet bit her lower lip again before she answered, almost whispering: "Yes."
Janet's brow creased as if she were wrestling with something. I guess she was digesting the idea that her brother had just flashed his cock to her and was wondering where to next. At first, she deflected us from the path we'd begun to take: "OK Mikey?"
"Yeah?"
"Truth. Did you have sex with Jackie Bennett?"
"No. I tried, but..."
Janet giggled -- tits jiggling, but I tried not to stare. There were a few more rounds focused on Jackie Bennett who was her friend's sister. Eventually she got to the embarrassing truth about my cumming too early and why she broke up with me. I wasn't too pleased so I wanted to change the subject.
"My turn. Truth. Were you ever unfaithful?"
"When I was married? No. OK truth: What do you fantasize about?"
I assume she was still thinking of my failed sexual adventures but I'd had enough of that and wanted to shock her. I couldn't lose. On one hand I might get a flash, on the other I might win the game.
