"My bad..." Lisa murmured with mock innocence as she closed the bathroom door behind her with a soft click, locking the door. Her eyes locked onto mine, sharp and unyielding, that familiar evil smirk curling her lips.
"I didn't know you were already in." she said slowly, voice dripping with false apology while her gaze roamed down my naked body, lingering shamelessly on my chest, stomach, and lower.
"I... I'm still bathing." I stammered, my voice barely above a whisper. Lisa ignored my words completely. She stepped forward with slow, deliberate strides, her bare feet making soft, wet sounds on the tiled floor.
The tiny white towel clung to her body, the thin fabric stretched over her curves. It barely reached the tops of her smooth, milky-white thighs, the hem teasing dangerously high with every movement, looking as though the slightest tug would make it slip and fall.
Her massive breasts bounced heavily with each step, the towel squeezing them together and pushing them up so high that the soft upper curves spilled over the top edge.
She stopped right in front of me, towering over where I sat on the bath stool. My face was level with her hips, and the towel gaped just enough at the bottom for me to catch a glimpse of her bare smooth and pink pussy.
My eyes betrayed me, drawn helplessly to the shadowed space between her thighs, the towel doing almost nothing to hide it.
"What are you looking at?" Lisa's voice came out low and dangerous, her tone sharp enough to cut. She tilted her head down, eyes narrowing as she stared right into mine. "Didn't you get enough of a look last night?"
I couldn't speak. The words died in my throat. I snapped my head down fast, staring at the wet tiles between my feet, cheeks burning with shame.
But my cock had other ideas. It throbbed hard, swelling quickly despite the cold water still clinging to my skin, rising straight up and straining against nothing now that I was naked.
Lisa's eyes dropped to it, and her lips curved into a slow, wicked smirk.
"Look at you," Lisa said softly, her voice thick with mockery and something darker, almost amused. "You really are a pervert, huh? Getting hard just from your big sister being in the same room."
"It's not like that" I mumbled, barely audible, my eyes glued to the white tiles between her legs. My face burned with shame, heart hammering so loud I could hear it over the drip-drip of the faucet. The bathroom felt smaller, the steam thicker, trapping me in the moment.
I closed my legs instinctively and placed both hands over my crotch, trying to hide the fully hard cock that refused to back down. It throbbed against my palms, hot and insistent, betraying me completely.
"Oh really?" Lisa raised an eyebrow, her smirk growing. She lifted one leg slowly, deliberately, her bare foot sliding through the air until her delicate toes brushed against my hands.
"Lisa..." My voice cracked, a jolt shooting through my whole body the moment her foot pressed against my shaft through my fingers. The touch was light at first, just the soft pad of her big toe tracing the outline of my hardness, but it was enough to make me twitch hard. Her skin was warm, and the pressure sent sparks straight up my spine.
She didn't pull away. Instead, she pressed a little firmer, her toes curling slightly as she rubbed up and down the length of me, slow and teasing.
The towel around her body shifted with the movement, riding up even higher on her thighs, the hem now barely covering anything. I could see the smooth, pale skin of her inner thighs, the faint shadow where they met, and the way her breasts rose and fell faster with her breathing.
"I didn't know my brother was this perverted." she said, voice low and dangerous. "Look at how hard you are."
I swallowed thickly, unable to look up at her face. My hands trembled against my cock, fingers clenched tight, but her foot kept moving. Slow, deliberate strokes that made pre-cum leak from the tip and soak into my palm.
"Lisa, please..." I whispered, my voice barely audible over the drip of the faucet, not even sure what I was begging for anymore, mercy, escape, or something I didn't want to admit.
Lisa didn't answer with words. Instead, she let her hands loosen just enough, and the tiny white towel slipped from her body in one slow, deliberate motion. It slid down her curves like silk, pooling silently on the wet bathroom floor at her feet.
Her naked body was revealed completely now, standing proud and unashamed in the steamy light. Her breasts were full and heavy, perfectly rounded with soft pale skin that glowed faintly under the bathroom light.
The light pink areolas were large, framing stiff, erect nipples that stood out like they were begging for attention. Her waist curved inward dramatically before flaring out into wide, womanly hips and a thick, juicy ass that jiggled slightly with every breath she took.
Between her strong thighs, her pussy was bare and smooth, the plump outer lips slightly parted, already glistening with a sheen of arousal that caught the light. A thin trail of wetness had started to trickle down the inside of one thigh, betraying how turned on she was despite her cold expression.
Every inch of her was soft yet powerful. Her curves that invited touch, skin that looked impossibly smooth, and a body built for sin. She stood there like a queen, completely in control, letting me look my fill while my cock throbbed painfully in response.
"If you can stay without cumming from just my feet." she said, voice low and mocking.
"Then I'll forget all about last night. Let's see how much control you really have, little brother." She laughed softly, the sound dark and knowing, echoing off the tiled walls. Her foot pressed down harder for a moment, pinning my shaft against my thigh with firm, teasing pressure.
"And who knows maybe I'll give you a little reward~" Her words increased my arousal more than I expected. A thrill of expectation shot through my mind.
She shifted her weight, placing both hands on the console table beside the sink for balance, her breasts swaying heavily as she leaned back on the table slightly.
Lisa's foot pressed down again, her toes curling deliberately around the throbbing length of my cock. She started stroking with slow, practiced movements up and down in a smooth, teasing rhythm that made it clear she knew exactly what she was doing. Her sole slid along the underside while her toes gripped the head, squeezing just enough to send sharp jolts of pleasure through me.
It looked like she had done this before, experienced and confident, controlling every stroke with precision. Her massive breasts jiggled heavily with each motion, bouncing softly in time with her foot's rhythm, the light pink nipples hard and straining against the air.
I tried to hold back, gripping the edge of the stool so hard, but it was impossible. The warmth of her soft foot, the slick pressure, the sight of her body moving above me, it all crashed over me at once.
