No way!

No

No, of course not

What the hell was I thinking?

"Yea, of course," I replied, my voice audibly wavering. "No problem." I could sense a hint of disappointment in Lauren's expression. "Take your time and come back down when you can. I'll tell the guys to cool it with the jokes for a bit."

"Don't worry about it," Lauren said. "I'm a big girl, I can handle it." I laughed, understanding the reference from something I had said to her many years ago.

"OK," I said, then I headed back out to the beach.

The rest of the afternoon went by relatively uneventfully and we found ourselves back in the house getting ready for dinner.

"I think your bathing suit worked," I set, sidling up to Chelsea from behind. I pressed my body to hers and kissed her exposed shoulder.

"I'd say so," Chelsea replied. She reached behind me to cup my bulging groin through my damp swimsuit.

"All the guys were staring at you," I said. I moved my kisses up the side of her neck. Her hand tightened around my package. "Even Liam."

Goosebumps formed on her exposed skin. I nibbled at her ear, drawing a soft whimper from her lips.

Then the bedroom door opened. It wasn't our bedroom door, though. It was Lauren and Liam's. We could hear it loud and clear since the doors to the bathroom were once again wide open.

"Shower's open," Lauren said. We could hear them giggling as she and Liam shuffled into the bathroom. We saw the door close slightly but it was left open enough to see their reflections in the mirror. Lauren was facing away from the mirror, her beautiful bikini-clad backside on display in the reflection. Liam was in front of her, mostly covered save for a sliver of his side and his hands which roamed up and down Lauren's body.

I jumped a bit as Chelsea began rubbing her palm across my erection. I had quickly gone from half-staff to rock-hard at the site of our two friends making out. My hands drifted up, finding Chelsea's left breast and cupping lightly through her tiny, red top. She let out a ragged exhale and her fingers curled around my shaft. Our eyes were fixed on the mirror as we watched Liam untie Lauren's top. Her beautiful, pale, sideboob fell into view as the top fell free and landed on her feet. Liam tugged the string to her bottoms and they followed, joining her top on the tile floor.

"Fuck, Chels," I gasped as her hand slid into my swim trunks. She grabbed a hold of my cock and began pumping. My left hand clamped down onto her breast and I pinched her nipple between my thumb and forefinger. Lauren's hands slipped to Liam's front and began rubbing aggressively at his crotch area. Then we watched as she undid the tie to his suit and began tugging it down. Inch by inch, it sagged lower until it finally joined Lauren's bikini on the floor.

Chelsea gasped as I snuck two fingers down the front of her bikini bottoms. They were soaked through, and not from the ocean. Liam was mostly covered by Lauren but, from the angle we stood, enough peaked out to see a slight, fuzzy patch of pubic hair and the thick root of his cock. Lauren reached down again. She took his erection in his hand, pulled it up, and began pumping.

Chelsea's pussy flooded my fingers, coating them in her juices, lubing them perfectly for me. She shuddered and bit her lip as I slid two deep inside her. Small parts of Liam's cock would become visible, flashing in the reflection as Lauren pumped away. Chelsea's movements on my own erection had lowered my suit enough that it eventually fell down completely.

Suddenly, and unfortunately, Lauren pulled open the shower curtain and they stepped inside. We heard them giggling again but their giggling soon gave way to "oohs" and "aahs".

Chelsea turned to me with a fire in her eyes. She grabbed me and pulled me on top of her, not even bothering to remove her bottoms. Instead, she just pulled them to the side and I slid right into her. God, she was wet.

She was also ravenous. With every withdrawal, I had to fight her grip as she tried desperately to pull me back inside of her. Liam and Lauren's orgasmic moans echoed off the porcelain shower and spilled out into our room.

How were they fucking in there?

Chelsea's breasts bounced wildly. More and more of her flesh was exposed as the flimsy strings to her top failed to keep it in place. I leaned over and sucked a nipple between my lips.

"AHHH!" Chelsea snapped. Her body jolted like she'd been electrocuted. Her thighs clamped to my hips. Her hands clenched my shoulder blades, pulling me into her. I directed my lips upward, kissing at the underside of her chin and neck. She went wild, bucking her hips back against me, panting heavily.

"Oh, fuck, Chels," I grunted as I felt her pussy tightening. I drove in harder. Deeper. My balls slapped against her taint. I placed my hands on the bed and pushed myself up, arching my back, lifting up onto my tip toes.

I lasted five more thrusts, each one more erratic until I clenched up, burying myself balls deep as I exploded. Chelsea's face contorted as my pulsing cock pushed her over the edge. At last, I collapsed on top of her, our bodies a mess of sunscreen and bodily fluids.

"I told you that bathing suit worked," I said. "God, you looked so fucking sexy." Chelsea smiled.

"Shower's open!" We heard Lauren's voice call out from their room then she closed the bathroom door on their side.
