The sunscreen smell hit me before I was fully awake, that coconut-and-salt cocktail that had soaked into every pore of the afternoon before. My cheek was pressed against the towel, sand gritting the corner of my mouth, and somewhere in the fog between sleep and morning I heard the low rush of waves and the sharp pop of a cooler lid.

I opened my eyes to grey light. Dawn. The sky was a pale wash of pink and blue, the sun not yet over the water, and the air was cool enough to raise goosebumps along my arms. I was still in my bikini from yesterday — the bottoms twisted sideways, the top strap slipped off one shoulder — and David was beside me, propped on his elbow, awake and watching something with dark, hungry eyes.

Karen was already there.

She knelt in the sand at David's hip, her fingers tracing the line of his shorts — the waistband, the seam, the shape of him underneath. Her hair was a mess of blonde tangles, her own bikini still on, and she looked up at me with a grin that said she'd been caught and didn't care.

"He's on the cooler, right?" she said. "So I'm just getting my deposit."

I blinked at her. "You're up early."

"Couldn't sleep. Too much anticipation." Her fingers walked the line of his shorts again, slow, deliberate. "And he's right here. Seemed like a waste."

David didn't say anything. His eyes were on me, not on Karen, and there was something in them — a question, a permission, a hunger that had been building since the beach went dark last night. He'd come inside me twice in the last twenty-four hours, and still he looked at me like I was the only thing he wanted to see.

I pushed myself up on my elbows. The sand was cool and damp beneath me, the tide line closer than it had been when we fell asleep. The cooler sat open beside Karen, a bag of ice melting inside, a watermelon wedged in the corner.

"Deposit," I repeated.

"Mmhm." She hooked her fingers into the waistband of his shorts and pulled them down just enough to free him. "You said he's on the cooler. I'm just making sure I get my share."

I watched her hand close around him.

He was already hard — half-hard, thickening under her touch, the skin flushed and dark against the pale morning light. Karen's fingers were sure, practiced, the same fingers that had been inside me yesterday, that had tasted my release off her own skin. She stroked him slow, watching me watch her, and I felt the heat climb my chest and settle low in my belly.

My hand drifted down between my legs before I even thought about it.

I was wet. Of course I was wet. I'd been wet since the moment I woke up and smelled sunscreen and heard that cooler lid pop. My fingers found my clit through the twisted fabric of my bottoms, and I pressed, just once, just enough to feel the spark.

Karen's grin widened. "There she is."

"Shut up."

"You're touching yourself already." She stroked him slow, thumb sliding over the head, and I watched him twitch under her touch. "I haven't even started yet."

"You're the one who woke me up with your hand on my husband's dick."

"Fair." She laughed, low and warm. "You want in?"

I should have said no. I should have rolled over and gone back to sleep, left them to it, let the tide come in and wash the whole thing away. But I'd been thinking about her mouth on him since yesterday — since she'd taken him in her mouth on this same beach, since I'd watched her swallow him down with Jodi watching, since the stranger in the peach sundress had joined in and made the whole thing feel like a scene from someone else's life.

I wanted in.

I pushed myself up off the towel and crawled over to them, the sand cool and wet under my knees. Karen shifted aside to give me room, and I sank down beside her, close enough to feel the heat off his skin, close enough to smell the salt and soap and the particular musk of him.

"That's it," she said. "Come here."

She kept stroking him, slow and easy, and I watched her hand move up and down his shaft, watched the way his cock filled under her touch, the veins standing out, the head slick with something that might have been pre-cum. My mouth watered.

I leaned in and licked him.

Just the head, just the tip of my tongue tracing the ridge, and I felt him shudder under my mouth. Karen's hand stilled, letting me take over, and I wrapped my lips around him and sucked him in — just the head, just the first inch — and tasted the salt of him on my tongue.

"Fuck," David breathed.

Karen's hand found my shoulder, squeezing. "That's it. Good girl."

I pulled off, just enough to breathe, and looked up at him. His eyes were dark, blown wide, his jaw tight. He was watching me with that same hungry look, the one that said he'd been waiting for this since the moment we met.

"You like that?" I asked.

He nodded, not trusting his voice.

I took him in my mouth again, deeper this time, letting my tongue flatten against the underside of his cock as I slid down. My hand wrapped around the base, the part my mouth couldn't reach, and I worked him slow and steady, my other hand still pressed between my own legs, rubbing my clit through the fabric of my bikini bottoms.

Karen watched. She didn't touch herself — not yet — but her hand was on my shoulder, her thumb tracing small circles against my skin, and I could feel her attention like a physical weight.

"You're going to make him come like that," she said. "Slow and sweet. You're going to swallow every drop."

I moaned around him, and I felt him pulse against my tongue.

Karen's hand slid from my shoulder down my arm, then to my wrist — the one wrapped around his base. She guided me, adjusting my grip, showing me the rhythm she wanted. "Like this," she said. "Tighter. Twist a little on the upstroke."

I followed her instructions, and the sound that came out of David was almost a whimper.

I pulled off, panting, and looked up at him. "You going to come for us?"

"Jodi—"

"I want to see it." I stroked him with my hand, slow and deliberate, watching the way his cock jumped under my touch. "I want to watch you come all over our faces."

Karen laughed, low and delighted. "Oh, I like that."

She leaned in and licked the side of his shaft — a long, slow stroke from base to head — and David's hips bucked off the towel. She did it again, and again, and I watched her tongue work him, watched the way she took him into her mouth and sucked, her cheeks hollowing, her eyes closed in concentration.

Then she pulled off and looked at me. "Together?"

"Together."

We leaned in at the same time. My tongue on one side of his shaft, hers on the other, our mouths meeting at the head. He was slick with our spit, hot and hard, and I could feel every pulse of his heartbeat against my tongue.

We worked him together — her mouth, my mouth, our hands tangled at the base, his cock sliding between our lips in a rhythm that felt almost like a dance. I could taste her on him, the faint salt of her, and I wondered if she could taste me too.

"Fuck," David gasped. "Fuck, both of you—"

I pulled off just long enough to say, "Come on. Come for us."

Karen took him in her mouth, deep, and I leaned in and licked the base, the spot my mouth had been neglecting, and I felt him start to shake.

"I'm going to—"

Karen pulled off just in time. His cock was slick and swollen, the head dark, and I watched it pulse once, twice, before the first hot streak of cum hit my cheek.

Then Karen's face. Then mine again, my mouth open, catching it on my tongue. He came in long, thick ropes, painting us both, and I felt it drip down my chin and onto my chest, mixing with the salt and sunscreen already there.

Karen laughed, breathless, and wiped a streak off her cheek with her finger. She looked at me, grinning, and licked it clean.

"Deposit made," she said.

I laughed, and the cum on my lips tasted like David, like salt and sex and the morning. I wiped my face with the back of my hand and looked at him — at my husband, sprawled on the towel, his chest heaving, his cock softening, his eyes dark and satisfied.

"Good morning," I said.

He reached for me, pulling me down against his chest, and I went willingly, my face pressed to his skin, his cum still cooling on my cheek. Karen flopped down on the other side of him, her head on his shoulder, and the three of us lay there in the grey dawn light, the tide creeping closer up the sand.

"The others are going to be here any minute," Karen said.

"Let them come." I closed my eyes, feeling the sun start to warm my skin. "We've got all day."

The waves rushed in, closer now, and I felt the cool water kiss my toes and retreat, leaving wet sand behind.

The water receded, and I opened my eyes to find Karen propped on her elbow, watching me with that lazy grin that meant she was already planning something. A streak of David's cum had dried at the corner of her mouth, catching the light like a secret.

"You've got sand in your hair," she said.

I reached up and found a clump of it, damp and gritty, woven into the tangles at the nape of my neck. "Comes with the territory."

"Mm." She reached over and brushed a strand off my forehead, her fingers lingering against my skin. "You know, when we planned this rematch, I didn't think we'd be starting before sunrise."

"Neither did I." I shifted, feeling the wet sand under my hip, the way my bikini bottoms had twisted even further sideways. "But you're the one who woke up hungry."

"I'm always hungry." She said it simply, like it was a fact of the natural world, and then she turned to David, who was still on his back, his chest rising and falling in the grey light. His cock had softened against his thigh, still slick with our spit, and I watched her eyes travel down to it, then back up to his face.

"You're going to be ready again soon?" she asked him.

He laughed, low and rough. "Give me ten minutes."

"I'll give you five." She lay back down, her head finding his shoulder again, and I felt the three of us settle into a triangle of warmth against the morning cold. The tide was creeping closer, each wave a little braver than the last, and I could hear the distant cry of a gull somewhere out over the water.

I let my hand rest on David's stomach, feeling the rise and fall of his breathing, the heat of his skin under my palm. The cum on my cheek had started to dry, pulling at the skin, and I didn't wipe it off. I liked the proof of it, the evidence that we'd started the day the way we meant to go on.

"You've got some on your chin," David said, his voice rough with sleep and satisfaction.

"I know."

"You're just going to leave it?"

"It's my deposit." I smiled. "I earned it."

Karen snorted, and I felt her hand find my ankle, squeezing once before letting go. The waves rushed in again, closer this time, and I felt the cool water swirl around my toes, pulling the sand out from under me.

"We're going to have to move up the beach soon," I said.

"Not yet." Karen's voice was drowsy, content. "The others aren't here yet. We've got time."

I looked past her, down the stretch of empty sand, the pale light just starting to warm the horizon. No one was coming yet. No cars in the lot, no voices carrying on the wind. Just us, the waves, and the smell of sunscreen and salt.

I closed my eyes again, feeling the sun start to touch my skin, and let myself drift in the warmth between sleep and waking.
