The Unexpected Truth Or Dare

[neerathemall]

And so it came to that. It was all over, the game was up and Olivia would have to deal with the consequences of her decision and face her friends. But when I turned towards my sister, I had a fraction of a second to realize that Olivia was going to kiss me. Her lips were on mine, her tongue against mine and for a long moment we kissed as passionately as we could.

When we stopped, the group, who knew nothing of the strangeness of what just happened, simply waited for Olivia's question, which led to dare and ended up with Ginger dancing topless for thirty seconds. While everybody was watching her, Olivia leaned into me and whispered "I'm sorry I kissed you... Just hang on for a few more questions and we'll try to put an end to this game. I'll owe you a big one! Thanks again, lover!" she was laughing as she pulled away, very drunk.

I nodded and brought my attention back to Ginger. But my mind was still reeling from the kiss, and how good it had been. My sister was a great kisser. Shit! Damn her! Why had she gone all in with that kiss? I had already been hard, and now that kiss, and Ginger's dance... It had all sent me in a state of serious sexual need. A few more rounds later, Olivia leaned in and whispered "You're a good kisser! I didn't know that!" I grinned, but inside I was all torn up.

Olivia was also still thinking about that kiss. When my turn came up, I decided to risk it and go for a dare. This time it was another guy, whose name I hadn't properly registered yet, who asked me to remove Olivia's top and bra. I laughed, but turned to look at Olivia. We shared a quick look before she shrugged and turned around.

My fingers were shaking as I unzipped the dress down to Olivia's waist. I was nervous because she was my sister, because it was all kinds of wrong, because I didn't want to do this, but most of all because I really, deeply wanted to see my sister's breasts. The guys made fun of me as I fumbled with Olivia's bra clasp, but none could know that all my previous girlfriends had had small breasts and most wore elastic bras. I had scant experience with full sized bras and their three little hooks. Eventually though, the black bra popped free, and so did Olivia's breasts.

I tried to hide it, but when I looked at her breasts, the ones I was supposed to know very well by now, I was floored. Her one piece bathing suit hadn't prepared me for Olivia's breasts. Not porn, not erotica, not glamour models. Nothing. Fucking hell! I was as impressed as the rest of the guys, and it took me a long time before I could tear my eyes away from them. When I did, looking at Olivia, she was grinning, barely shy at all and clearly enjoying the attention.

Three girls and four guys were now topless, and the next dare turned the heat up another notch. Not only had partners been asked to perform sexually explicit acts, Ginger had even sucked her boyfriend for thirty seconds, but suddenly Jenny asked Olivia to suck on Christopher's cock. His own girlfriend only laughed with the rest of them. Most of the group were looking at me, but I had absolutely no idea how to react. I was supposed to play the slightly put off guy, a bit jealous but not too much given the general atmosphere, but I was also seeing my sister sucking a cock and most importantly, I was extremely turned on by the sight. I had no idea how I was reacting and thought myself lucky that most of them were too drunk to really care.

Ginger saw me touching my cock through my pants and said it out loud. "Oooh! He wants his fair share! Ok then! I want that the next dare on me be that I have to suck Ethan's cock!" Shouts of laughter burst out at this strange request, and one minute later I was being expertly sucked by this intense girl. I lasted the thirty seconds, which seemed to be the designated length for the dares, but fifteen seconds more I would have burst a nut in her mouth. Looking at Olivia as I was being sucked was, so far, the strangest experience of the night. Oh, that and the kiss. Shit, what a fucked up night!

And it was only going to get weirder. When she pulled away from my cock, Ginger pulled my pants all the way down, and so I became the second guy to be fully naked. A few minutes later, the first time I saw a cock enter a pussy, between boyfriend and girlfriend, of course, I began to be really nervous. Olivia looked at me and I saw that she was scared as well. She tried to tell them that it had gone far enough, that she didn't want me to think that they were all perverts. "Sush!" Christopher replied, his eyes still glued to the penetration. "You've seen and done much worse than this my dear! If he doesn't know that about you, it's high time he did!"

Olivia looked at me with eyes wide opened, both because her attempt had failed and because I was, in fact, learning a lot about my little sister. But knowing that she had likely participated in an orgy was one thing. Having sex with her, was quite another. I leaned closer to her and whispered "We can leave whenever you want... This is getting crazy, especially for us."

"I know! It rarely goes this far, you have to believe me!" was her reply, whispered in my ear as well.

But despite the words, we were leaning against each other and I could feel her naked breast against my equally naked torso. I was also extremely aware that her hand on her own thigh was only inches away from my hard cock. And despite the four other sexually attractive girls here, my mind was focused on my sister. We knew we had to get up and leave, even if it meant breaking up the little private party, but neither of us moved or said anything. The only thing I could do was to always tell the truth. But with the late hour and the alcohol, I made another mistake and had to take a dare. "Suck Olivia's tits!" was Jenny's order.

Last time I had turned towards Olivia after a crazy dare, she had leaned in and kissed me as if it was the most natural thing in the world. This time though, she seemed afraid. She was laughing, but I could see that she was nervous and really didn't want that. We looked at each other, grinning to keep the pretence up, but I waited for her signal. When she nodded very slightly, holding her two breasts in either hand, my stomach lurched. This was nearly as wrong as it got. But before I could fully form the intention of leaning in, I saw myself doing it, my mouth wide open until I sucked my sister's nipple deeply inside my mouth.

At first I managed to restrain myself and mainly made a show of it. But then I decided to enjoy it a bit more. Just as I closed my eyes to focus entirely on the direct physical sensations, I felt Olivia's hand on my cock, squeezing the base. One of the biggest shocks of the evening. So wrong, so terribly good. I wasn't expecting her to do that at all, but as I knew that thirty seconds was pretty short to enjoy such breasts, I abandoned any and every restraint and reserve I might have had.

I had never sucked on such a large breast before, and it had never felt like I was missing something. But now, dear Gods in heaven, I was overwhelmed. Smaller breasts truly are soft and pliable and smooth and gifts from nature. But these... Oh my Gods. These were beyond imagination. I had never thought that big breasts could feel so differently than smaller ones. Sure I had expected the size, but it seemed like it was so much more.
