This was going to be a great weekend. A cabin near the lake and enough alcohol to make sure we would be very sick in the mornings. We all took the day off uni and arrived at the cabin about lunchtime on Friday.
There were 6 of us all up, all 19 years old. Mark and myself (Pete) were the guys and Sarah, Mel, Paige and my twin sister Ashley were the girls. I have always been tight with my sister from when we were very young and the rest of us have been friends since the beginning of high school.
It didn't take us long to get the booze once we got there and before long we were all at the lake swimming and drinking.
After our BBQ dinner we were all sitting around drinking when Mark had the idea of playing some drinking games. After a couple games of Kings Cup and Fire and Ice, Paige suggested poker with the loser of each hand taking a drink.
We played a few hands before Mark suggested we make the stakes a bit higher. "Let's play drinking strip poker. Loser drinks and takes off some clothes."
We were all pretty well on the way to drunk so this seemed like an excellent idea. I didn't even think that I could be getting nude in front of my sister.
As we were all sitting inside, we didn't begin with many articles of clothing, shirts and pants only, nobody was wearing shoes or socks.
"Since there are 6 of us, the 2 losers should drink and strip," suggested Mel. "We'll get more drinking in that way."
The game started and I regretted it straight away. First 2 hands I lost and I was already down to underwear and shorts. Mark lost his jumper and Sarah her top.
The next hand I was confident having a pair of aces and my sister and Paige lost their tops. This was the first time I realised I was going to see my sister nude. Here she was sitting across from me in her lacy black bra and I couldn't help but look.
"Hey pervert, stop looking at your sister's tits," yelled Sarah.
Everyone laughed and Ash's face reddened. "Ok, I'll look at yours instead then," I responded.
Mel and Sarah lost the next hand and Mel then realised things were unfair. "Hey, I'm wearing a dress, I have one less item then the rest of you."
"Too bad take it off," said Sarah as she took her pants off. Mel did so reluctantly, she was the most shy out of the six of us but in my eyes she was by far the most attractive. Tall, skinny with long blonde hair and now looking at her in just her matching green bra and panties I could see her perky set of C cup tits.
Ash and Mark lost the next hand and now I saw my sister in her bra and panties as she removed her skirt. Damn my sister had a hot ass.
"O crap," I said as I got my new cards, "I mean, woo hoo, what awesome cards I have here. You should fold now."
"You dork, no one is going to fold because you lose either way," Ash laughed.
I lost and so did Mark. That was the worst possible result. No boobs in this round as Mark and I lost our shorts and drank the last of our bourbon.
"Gotta get more alcohol, we'll be back," Mark said as we stumbled out the room to find more.
"Dude we are going to see these girls naked very soon," Mark told me as we were out of sight. "I'm going to be hard as soon as I get these off. You better be hard too so I don't get embarrassed."
"No worries man, mine's already moving."
Mark and I have always been close. We are about the same height and build and have been mistaken for brothers in the past. The only difference is that I have brown hair and Mark blonde. We have seen each other in the gym showers at uni and I have noticed that our penises are around the same size. Mine is slightly longer but his is a little thicker.
"Dibbs on Paige tonight dude," Mark said.
"I knew you had a thing for her. Why haven't you had a crack yet?" I asked.
"I dunno, shy I guess. Which one do you want?"
"Mel I guess but I'm not picky." I responded.
"Really?"
"Yeah, they are all hot."
"Even your sister?"
"O yeah, I forgot about her."
As we returned to the girls with our new Jack Daniels', the girls all seemed to stop talking. I wondered what they were discussing, hoping that they weren't going to pull the plug on this game too soon.
We sat down and Paige dealt. I breathed a sigh of relief when I saw 2 Kings but looked in Mark's direction and he looked worried. Turns out it was for a reason, he had nothing and either did Paige. I ended up with 3 Kings, my best hand of the night.
All the girls were now sitting around the table in their bras and panties, me in my underwear and Mark was naked. He was trying to cover himself with his hands but we all knew he was erect.
"What happens now?" asked Mark. "Do I keep playing? I have no clothes to lose."
Paige stepped in, "How about if you lose when naked you drink and the winner gives you a dare."
"I like it," said all the girls at the same time.
Mark and I looked at each other, that was too much of a coincidence to happen at the same time. This is what they were discussing when we were out of the room.
We continued on with the game and this time Ash and Paige lost. Without any hesitation they both took their bras off and for the first time in my life I was looking at my sister's tits. My sister was gorgeous. She was shorter than me but with the same brown hair only longer and perfect B cup boobs with small pink nipples. She saw me looking and gave me a little smile.
Mark's eyes were glued to Paige's chest and he looked very uncomfortable sitting there nude. Paige was the ranga of the group, a tall redhead with freckles and she even had some on her pale boobs. She had the smallest boobs of the group, A cups with tiny nipples.
At the end of the next game Mel was down to just her panties and Paige was now sitting naked next to me. She had a thin strip of red pubic hair visible to everyone and now Mark had forgotten to hide his erection which Paige was obviously looking at.
