The group had settled deep into the rhythm of easy chatter now, voices overlapping in the steamy haze like they did at every backyard gathering. Lisa leaned in closer on my other side, her wineglass balanced precariously on the tub rim, launching into a detailed rundown of her latest dinner party experiment—some complicated roasted vegetable dish that had apparently gone sideways with too much garlic. I nodded along, murmuring the right encouragements, my own glass clutched tight in one hand while the hot water lapped at my chest. The strong currents from the jets pounded steadily against my lower back, turning my skin hypersensitive, every bubble popping like tiny electric kisses along my thighs.
Jake’s hand rested fully on my thigh under the thick foam, no longer pretending at accident. His fingers traced slow, lazy circles just above my knee, each pass sending fresh sparks racing upward. The water made everything feel amplified—his touch warmer than the surrounding heat, his skin slick and insistent. I tried to keep my face relaxed, laughing softly at Lisa’s story about the burned edges, but inside my thoughts fractured into sharp, guilty shards. This is Mark’s coworker. We’re in public. What the hell am I doing? The guilt only made the growing wetness between my legs more insistent, a heavy throb that had nothing to do with the tub’s temperature.
He joined the conversation seamlessly, his voice steady and casual as he tossed in a joke about his own failed attempts at grilling last weekend. No one would have guessed his fingers never stopped their deliberate tease, drawing wider circles now, inching higher with each rotation. The faint metallic tang of chlorine lingered on my lips every time I sipped my drink, mixing with the distant woodsy trace of his cologne that somehow cut through the steam. My nipples strained against the thin suit fabric, taut and tingling from the cool evening air that kept brushing my shoulders whenever the bubbles dipped.
The group’s laughter swelled around a weekend plans story from the couple across the tub. Jake’s hand slid higher, bolder now. His fingertips slipped just under the leg opening of my one-piece, grazing the smooth inner skin of my thigh before brushing the swollen outer lips of my pussy. No penetration, just the lightest graze, but it stole the breath from my lungs. I bit down hard on my lower lip to stay neutral, forcing myself to answer Lisa’s direct question about what sides I usually pair with roasted vegetables. My voice came out even, almost normal, but my legs trembled under the surface as another rush of arousal flooded me, soaking the suit where his fingers hovered.
Someone shifted beside us—maybe the woman on Jake’s other side adjusting her position—and the water sloshed harder for a second, nearly thinning the foam veil. Panic spiked sharp through the haze of want. I froze, certain the movement would expose the way his hand disappeared between my legs, but the bubbles foamed back up thick and forgiving. Jake didn’t pause. His fingertips traced along my pussy lips now, slow and exploratory, feeling the slick heat there even in the scalding water.
“So fucking smooth,” he whispered during a lull, voice low and rough, lips barely moving against the shell of my ear. “I can feel how wet you are even in the water.”
The words landed like a slow stroke right to my core. Part of me screamed to close my legs, to shift away, to end this insanity before it went further. The rest of me—the part that had my hips giving the tiniest, involuntary rock—wanted to spread wider, to chase the pressure building low and heavy. Mark’s voice drifted over from the deck again, clear and affectionate. “Babe, you need another drink? I can grab you one.”
