My bikini was too small at the beach…

The next time we went to the beach, I knew I wanted to push it further. For some reason, the idea of teasing him had become kind of an obsession of mine; something I had thought about regularly since our last trip, especially late at night with my hands between my legs.

Not that I would ever admit that to him.

Or even to myself, really. Josh was my best friend, and I'd never do *anything* to jeopardise that. Except, of course, my pussy had other ideas.

We didn’t talk about what had happened last time, but I felt like maybe something had changed between us. Not on the surface, but like…underneath. Something unspoken, I guess. I could feel it in the way we didn’t message each other for the next few days, and the way his voice was a little more hesitant to answer when I called him, like he was trying not to remember the feel of my nipples under his thumbs.

“Hey, want to go to the beach again? I had fun last time…”

“Oh…uh…yeah, sure!”

The next day we drove to the beach just as before, as if nothing had happened, chatting about dumb memes, video games, and our friendship circle.

Everything was normally, almost as if my huge naked tits hadn’t been in his hands a week ago. As if we weren't on our way back to the place it had happened. As if we both hadn’t been making ourselves cum to it for the past seven days.

Well, I had, anyway.

We parked, grabbed the bag, and started toward the same patch of sand. I let my dress ride up a little as we walked, pretending not to notice when the wind blew it up, revealing a flash of my ass, pretending I couldn’t feel him looking. Pretending I didnt like it.

We reached the sand and I spread out the towel while he rummaged through the cooler.

“I’m gonna get changed,” I said, already pulling the dress over my head, confident this time, wanting him to see the scrap of red fabric that barely clung to my tits, the material stretched taut, the underside of my breasts clearly visible. This time, I’d bought the bikini specially, ordering it online after a few glasses of wine.

The front of the bottoms dipped so low that the line of my pussy was barely covered.

Josh didn’t say anything. He just blinked.

Then blinked again.

“Too much?” I teased.

His voice was strained. “No, it’s…good...”

I smiled and stretched, arching slightly, letting my breasts lift and sway with the motion. He lay down on the towel. I joined him, propping myself on one elbow.

We didn’t speak for a while. Just listened to the waves and the distant chatter of other beachgoers. I shifted onto my stomach, spreading my legs a little. The bikini bottoms tightened between my thighs. I wriggled, pretending to get comfy, knowing full well what the motion would look like.

“Want me to put sunscreen on you again?” he offered.

“No thanks,” I said, smiling. “I put some on before I came.”

“Oh,” he said. “Fair enough.”

I felt a little flush of excitement at his disappointment, at the way my body was almost completely on display to him but now out of reach.

So close yet so far.

I felt my pussy throb a little. I was enjoying teasing him now.

“Shall we go for a swim?” I asked.

Josh looked over, eyes flicking to my chest, then quickly away again. “Yeah,” he said, clearing his throat. “Sure.”

I stood, slowly, brushing sand from my thighs, then turned and started walking toward the water without waiting for him. I let my hips sway more than usual, the strings of the bikini tugging with every step. Against my hips. Against my clit. I could feel the air on my skin, feel the bounce of my ass with each step. I didn’t look back—but I hoped he was still watching.

The water was cold at first, and I gasped when it touched my pussy, the contrast of temperature making me clench.

Josh waded in beside me.

“Nice of you to join me,” I said teasingly, splashing him and then ducking under, letting the water slick my hair back. I surfaced, rubbing the water from my eyes.

Josh stared. His mouth opened, then closed again.

“What?” I said, following his line of sight, looking down at myself. Fuck. The ocean had turned the red bikini practically transparent. The fabric clung to my nipples, the outline of them completely visible, and my smooth pussy had nearly completely swallowed my bikini.

I know I wanted to tease him but fuck.

I looked like such a slut.

I dropped back into the water, my tits bobbing just beneath the surface. Every little shift made them brush against the fabric, sending soft jolts through my nipples. I reached up, adjusted the top and watched him pretend not to notice.

I let myself float backward slightly, the mound of my pussy rising above the surface of the water, my legs scissoring just enough to part the fabric a little.

His eyes followed the motion.

I brought one foot up between us, pressed it lightly to his thigh, and gave the gentlest push. “You going to swim or just stare at me all day?” I teased.

“I wasn’t staring!” he protested, his face suddenly filled with embarrassment. “I was just–”

I splashed him. A big wave. Right in the face.

“Hey!” he gasped, blinking water away. “No fair!”

“What are you going to do about it?”

I splashed him again.

He lunged, and I shrieked, laughing, trying to dodge. But he caught my waist under the water and pulled me close. His fingers gripped my bare skin, pulling me onto his lap as I struggled, and just for a second, I felt it, hard and long, pressed between my ass cheeks.

He was hard as fuck.

I reached up and tucked a wet strand of hair behind my ear, letting my elbow lift, letting my chest rise just a little from the water. The fabric of my bikini shifted again.

Josh’s eyes dropped. Then back to mine. He was breathing hard. So was I.

“Sarah…” he started. “Do you–”

I didn’t hear the rest because I ducked under the water again, pushing away from him, swimming beneath the waves for a moment, trying to create distance…

…trying not to imagine him pinning me down and fucking me with what I had felt between his legs.

Because it was Josh.

My best friend.

And having his cock in my mouth, or his cum on my nipples, or his fingers deep inside me was the last thing I should be thinking about.

So I swam out a little deeper, pretending not to care.

Josh followed...
