Rip the curtains open

My immediate thought was to slam the curtains shut but my body didn't react. Instead, I did the opposite, ripping the curtains open wide.

"What are you doing?" Scott asked, surprised.

"New plan," I said as I bounded back to the bed. Scott looked past me to see the couple. They both had large smiles on their faces. Scott looked at me.

"Are you sure?"

"Yes," I said. I laid down on my back and elevated my hips. Scott got the picture. He gripped my ass with one hand while sliding himself inside me with the other. Using his kneeling position to gain solid leverage, he began thrusting into me.

"Hard," I said. He obliged, pounding into me, sending his thighs smacking against my ass. My tits bounced around, jiggling as they settled on my chest only to be shaken and sent bouncing again.

"Yes, yes, yes, yeeeeeesss," I moaned with every thrust. Scott's gaze shifted from me to the window. I gazed back to find the woman, topless, her hand clearly down the front of her partner's swimsuit, pumping in rhythm while her partner worked his fingers into her bikini bottoms.

Was that allowed? I thought. I know there was a "strict" no-nudity policy in the hotel area but technically they weren't showing anything off. The scandalousness of it all just made it all the more exciting.

"Harder," I begged. Scott grunted, bottoming out. His body was tensing up. I saw peaks of his abs as the muscles tightened.

We caught each other's eyes. "Cum on my tits," I whispered. Scott's eyes shot open. "Do it, cum on my tits!"

Scott went for broke, somehow pounding faster and harder. He grabbed my tits and squeezed, the soft, pillowy flesh mushing through his fingers. His eyes scrunched, then one, two, three jerky thrusts before he pulled out.

"YES!"

"AAAAHHHHH!" he groaned as he detonated. The first blast hit the underside of my breast before the next two landed directly between them. I scooped my tits together as cum splashed down over my nipples. Just when I thought he was done he jerked it one more time and sent a final rope right in the crevece between them.

Scott and I looked at the window to see the couples still going at it. Their hands were a blur as they braced themselves on the side of the pool, shaking visibly through powerful orgasms.

Finally, their bodies relaxed as they both took a moment to catch their breath. They looked up at us and smiled then climbed out of the pool. For a moment I thought they were coming to us, that they would knock on our door. I froze in anticipation as we watched them turn at the last moment toward their own room. I looked at Scott who stared back at me in wonder.

"I think I need another shower," I said, still trying to catch my breath, my chest heaving with exhilaration.

"I was not expecting that," Scott said as he looked me up and down, coated in his sticky seed.

"I had a feeling you'd enjoy it." I gave him a sexy grin.

"Whoa yea," he replied with a chuckle. "It's been awhile. God, that was so sexy."

"Which part?" I asked. "The performing for the other couple or the cumming on my tits?"

"All of it," He replied. "And you, you are so fucking sexy."

We certainly weren't making out of the shower this time without "getting dirty" again. Scott pinned me to the wall, thrusting up between my legs. I arched my back, shoving my soapy breasts into his face. Then he turned me around and pounded me from behind. I gripped the top of the shower, my ass pushing out, receiving every one of his powerful thrusts. My breasts swung wildly, slapping against the glass door. I had to quickly grab onto the towel rack to keep myself from slipping as Scot came, triggering a powerful, knee-shattering orgasm of my own.

I was so horny I could have gone for round 3 after the shower but I knew Scott wouldn't be able to and I didn't want to **** him. He could sense that I was still frisky though by the way I was cuddling up to him and making sexy eyes, and what a lover he is as he kissed me all over my body before going down on me. I moaned and squirmed through two more orgasms before I told him to stop. Not that I couldn't keep going, I was so fucking horny I could have kept going until the sun came up but I wanted to give Scott a rest.

"Are you sure?" Scott asked as he ascended up my body with kisses, stopping at my lips. "I can keep going."

"No," I told him. "Just hold me."

"I'd love to." Soon we drifted off to sleep, my ass nestled into his crotch, his arms wrapped around me, cupping my breasts.
