His words hung in the steam like a promise I couldn’t refuse—”I’m so fucking close...”—and the low growl of them vibrated straight through my spine where his chest pressed flush to my back. We were still locked in that tight spoon along the bench, my body tucked perfectly into the curve of his, my ass nestled against his hips while the rest of the party swirled on around us. Lisa was mid-story about her disastrous attempt at homemade sangria, her laugh bubbling up just as loud as the jets. Mark’s voice carried from the deck, relaxed and easy, trading barbs with Dave about the latest game. No one had any idea that Jake’s thick cock was buried to the root inside me, stretching my married walls in this slow, devastating grind.

I kept my face turned toward the group, lips parted in what I hoped looked like easy enjoyment of the warm water. But underneath the foaming veil, my pussy was clenching greedily around him, every lazy roll of his hips dragging that blunt head along the front wall of my core where it lit up every nerve. The hot water made everything feel impossibly slick, like liquid silk sliding between us, but I could still feel the distinct throb of his veins, the way he swelled even thicker with every controlled thrust. His finger stayed lodged deep in my ass, curling in perfect time with his cock, the dual pressure turning every breath into a silent shudder.

“Hold still for me, Emily,” he breathed against the shell of my ear, so quiet it barely disturbed the steam rising off my wet shoulders. “Let me fill you up right here while you pretend you’re just relaxing.” His hand on my throat tightened a fraction more—not enough to cut off air, just enough to make the world tilt soft and dizzy at the edges. Stars sparked behind my eyes. My blood roared in my ears, a rushing sound that almost drowned out the chatter. Guilt slammed into me like a cold wave crashing over the heat: Mark is right there, beer in hand, smiling at something Dave said, and I’m letting his coworker pump me full in front of everyone. The shame only made my inner muscles flutter harder, milking him like they had a mind of their own.

His free hand slid up under the water again, cupping the heavy swell of my left breast. Fingers dug in possessively, kneading the soft flesh while his thumb found my nipple and pinched—harder than before, twisting just enough to send a sharp bolt of pleasure straight down to where we were joined. I had to lock my jaw to keep from moaning. The cool night air kissed the tops of my breasts whenever the foam dipped low, turning my skin to gooseflesh while the scalding water and his warm palm made everything below feel molten. My soft belly pressed tighter against his forearm as he pulled me closer, the gentle give of my body molding to his like it belonged there.

The group’s laughter swelled again. Someone across the tub made a joke about weekend traffic, and I forced a breathy chuckle that came out far too husky. Jake’s hips rolled deeper now, the strokes still hidden but no longer lazy—long, deliberate drags that pulled him almost all the way out before gliding back in so slowly I felt every inch claim me. His finger in my ass pressed forward, rubbing against the thin wall separating the two intrusions, turning the fullness into something overwhelming. Pleasure coiled low in my belly, tighter and hotter than anything I’d felt all night, a heavy, aching pressure that made my toes curl beneath the turbulent surface.

I shouldn’t want this. I shouldn’t be rocking my hips back in tiny, secret circles to meet him. But God, the way he filled me—bare, raw, no barrier between us—made my mind blank out in white-hot flashes. He’s going to come inside me. Right here. While Mark watches from five feet away. The thought sent a fresh gush of wetness flooding around his cock, easing the glide even more. Jake felt it. His breath hitched against my neck. “That’s it ... soak me, married girl. Get this pussy ready to take every drop.”

His hand on my throat tightened again, the light breath play pushing me right to that dizzy edge where the world narrowed to nothing but the thick slide of him inside me and the relentless squeeze on my breast. He pinched my nipple in time with a deeper thrust, rolling it between his fingers until the sting melted into pure liquid heat. My vision blurred at the edges. The jets pounded against my lower back, adding their own pulsing rhythm, while the foaming water hissed and swirled around our joined bodies, hiding the way my hips were starting to move with more urgency.
