Surprise!

I was dizzy from what had just happened. The sun was barely down and I had already watched Chloe, my wife's sister, masturbate as I looked through the keyhole at her. I had already been caught by Chloe, who just waved and smiled at me before passing out. I had also been caught by my wife, Sarah, as I spied on Chloe. Sarah had pulled me into the bathroom to have sex. Then, to top it all off, my wife had told me to think of Chloe as I came in her. I couldn't believe it all had happened. Now, my wife was up to something. Whatever it was, I was overwhelmed by the anticipation.

So, I did what she had said. I started to shower, feeling the hot water cover my skin as I daydreamed of Chloe. As I soaped up my face, I heard the door open.

"Michael, it's me," Sarah said, "I need to go."

"Okay," I replied, half-listening as I continued to think about Chloe.

"Hurry up in there, okay?" Sarah said as she flushed.

"What's going on?" I asked, remembering what she had said earlier.

"Nothing," she said, giggling.

"Bullshit," I said.

"Nothing," she said again, and shut the lights off on me as she left the bathroom.

"Hey!" I said, getting soap in my eye in the process.

Sarah was usually feisty, but she was really on one. My own wife had told me to think of her sister as I came in her! What the hell was that about? I worked my eyes clear of soap as I felt a hand on my stomach.

"Sarah, what the hell?" I said, trying to see what she was up to.

"You liked watching Chloe?" I heard her whisper as she ran her hand across my chest.

"Yeah, look, are you pissed? I'm sorry-." I started.

"Shh, just keep your eyes closed and think of her. Just think of Chloe, Michael," she whispered in my ear.

I was becoming hard, my heart flushing my body with blood at the thought of Chloe and Sarah. One mine, one forever out of reach, but both driving me crazy with passion. I did as she said and braced myself against the tub, awaiting the inevitable caress of my wife's loving hands and mouth.

I heard her slip into the tub as she gently maneuvered me around. As I went to touch her, she pushed my hand away and giggled.

"No hands, Michael," she whispered as her hand slipped down onto my cock.

I felt a rush of excitement as she began to work me. She was breathing heavily as she worked me harder and harder. The steam from the shower poured over me as her mouth encircled the tip of my cock.

I gasped as I felt her gently lick the tip. My god, it was incredible!

"Imagine that this was my sister, Michael. Imagine Chloe's lips on you!" she hissed as she swallowed me deep down her throat.

This was too much for me to handle! I couldn't believe that Sarah would act like this, not in a million years. She always seemed so jealous of Chloe and my attraction for her. Was she trying to upstage her? My head flooded with thoughts as her tongue rolled in flashes around my cock. She was doing her best to pleasure me, doing things I never knew she could. Grasping the shaft, she began to pump it quickly as she sucked up and down the tip. I was so close, so very close.

"Come in my mouth, Michael, come in Chloe's mouth," she whispered with one final lick to put me over the edge.

I did as she said, releasing my semen inside her as I shivered and gasped from my orgasm. It lasted and lasted as I felt her mouth work on me with each pulse of come. She slurped and licked until I couldn't take any more. I gasped and pulled away, falling gently into the cold, wet tile.

"My god, Sarah. That was wonderful. I love you so much," I said, breathless.

"Who said I was Sarah?" the voice said.

My heart skipped as I opened my eyes. Chloe, naked and grinning, was kneeling before me. I couldn't believe what had just happened, what was happening now! Her beautiful baby-faced image burned into the back of my eyes as I stood paralyzed before her. She was my wife's sister and I had just come in her mouth! She was naked in the shadows before me; her body that was hidden for so long was revealed at last. I stared at her in awe, straining to see her form. What the hell was going on?

"Sarah knows. She's the one who came up with this, okay? Don't worry," Chloe said as she stood up to show me everything she had.

Her body glistened in the shadow as she moved close to me.

"God, you're beautiful," I said as I gazed at her.

Her breasts were small like Sarah's. She had the same tiny nipples as Sarah did. She had the same hands, too, as I had just recently found out. Her flesh was enticing, but I felt very hesitant. I felt like I was cheating on the woman that I loved. I hadn't been with anyone else but Sarah for four years now, and here was her own flesh and blood inviting me in for the taking.

Chloe sensed this and stepped back a step. Still smiling, though, she began to lather up with my wife's body wash.

"Are you mad at us?" she asked.

"No, Chloe. Admit it though, this is kind of fucked up, isn't it?" I said as I slowly reached out to touch her hot, wet skin, stopping only an inch away.

"Don't fight it, Michael. Really, I've wanted you for a long time. Sarah isn't stupid. She knows you want me. That's why she's doing this," Chloe said as she finished soaping her body.

She moved past me to rinse off. Her slippery body rubbed across me, her flesh caressing every inch of me that faced her. As I turned with her, my hard cock slipped in between her thighs and across her smooth pussy. I definitely wanted her. I wanted to be in her right now. She knew it, too. She stopped and spread her legs slightly as she looked into my eyes. My chest tightened as I felt her wet labia on my cock. Involuntarily, I eased forward slightly and felt myself slip across them. We gasped together as her soapy chest pushed against me. This was it, I couldn't take any more. Chloe Lawson, my wife's sister, was mine. We kissed deeply as I picked her tiny body up in my arms, my strength fueled by passion. She giggled and licked my neck as I thrust at her, sliding deep into her wet hole. She was tight and warm, inviting me deeper and deeper. Her pretty, innocent face shined in the dark shower, her soft lips curling from our pleasure. I felt like an animal, on fire and hungering for her flesh. I fucked her hard as I gripped her body tight. The new sensation of a different woman's pussy overwhelmed me. They were very similar, but just different enough for me to know, full and well, that it was Chloe I was inside of. It was just enough to know that I was sharing something that I had shared with only one other woman in four years. Chloe had always been separate from me, always platonic and off-limits. The world had changed suddenly with what was happening now.

"Oh, God, fuck me Michael! Come inside me!" she moaned in my ear.

"Oh, fuck, Chloe, I can't believe this!" I said as I thrust harder and harder.

We fell out of the shower and onto the rug as we kissed and nibbled each other all over. It was an orgy of flesh and plastic; Chloe and I twisting under the shower curtain together. The plastic stuck to us as we fucked and fucked, crinkling from our motion. The new flesh, the strange skin wrapped around my cock, Her moaning; it was all consuming me as I tasted her kisses and smelled her excitement beneath me. Her body, a stranger's body, moved under me differently than Sarah's, but it was still so very familiar; as if Chloe knew what to do to give me the most. She licked me and rubbed her hands across my ass, grabbing it and pulling me deeper into her. She bit my neck and began to moan lauder and louder. This was it. She was close.

"Oh, Michael, I'm coming! Oh, yeah, fuck me!" she said as she tensed up and arched beneath me.

I watched her smile and bite her lip, lost in the waves of pleasure. I was close, so close to filling her up. This was unbelievable! Chloe's wet, soapy body stretched out underneath me as she ran her hands down my back.

"Come on baby, come in me. I want it, baby," she said as she squeezed her vagina muscles around my cock.

As I closed in on my orgasm, the room filled with light. Sarah, out of the corner of my eye, was standing there watching us from the doorway. As I looked up at her, I began to come in her sister. Sarah's eyes were on fire, enjoying the show immensely. I looked down at Chloe as I began to squirt my hot load deep within her. I gasped as I felt the wave of my orgasm consume me. Chloe was mine. I had come deep within her as my wife watched with approval. What a day.

"You broke the shower, lover," Sarah said.

Chloe laughed as I rolled off of her and into cold, wet plastic.
