Forbidden Shower Encounter: Step Bro Catches Step Sis Alex Blake in the Shower and Gets a Blowjob!

The humid air hung heavy in the bathroom, thick with the scent of Alex's floral shampoo. I shouldn't be here, pressed against the doorframe, listening to the water cascade over her skin. My step-sister. But I was. And I couldn't tear myself away.

A bead of sweat trickled down my forehead as I imagined her beneath the spray. I knew this was wrong – totally taboo – but the thought of her naked, vulnerable, sent a jolt of electricity through me. The sound of her humming under her breath was almost unbearable.

My hand trembled as I reached for the doorknob. I pushed it open slowly, silently. The steam swirled, partially obscuring my view, but there she was. Alex Blake, her skin flushed, her hair plastered to her back. Her big ass was breathtaking.

She gasped, startled. "What are you doing here?!" she whispered, grabbing for a towel.

I stammered, trying to explain, but the words caught in my throat. My gaze dropped, fixated on the curve of her breasts, the way the water clung to her skin. "I… I didn't mean to…"

Her eyes narrowed. "Get out!"

But I couldn't. I was frozen, captivated. I knew I was crossing a line, committing a sin. Yet, something primal inside me wouldn't let me retreat.

She saw the desire in my eyes, the undeniable lust. A strange look flickered across her face – a mixture of anger and… curiosity? "You're really doing this?" she breathed, her voice barely audible above the rush of the water.

I swallowed hard, taking a step closer. "I can't help it, Alex. I… I want you."

Her breath hitched. She hesitated, then slowly, deliberately, dropped the towel. My heart hammered against my ribs. Her body was incredible, and she was mine, even for this fleeting moment of step-fantasy.

Without a word, she reached out, took my hand, and guided it between her legs. Her fingering was expert, teasing. I moaned, lost in the sensation. She then pulled me close, her wet body pressed against mine, and whispered, "Suck me."

My head swam. This was happening. I dropped to my knees, my mouth finding her hardness. Her moans filled the room as I gave her a deep blowjob, her fingers tangling in my hair. This no condom encounter was both forbidden and intensely erotic. The pleasure was overwhelming. My cumshot sprayed over her stomach, marking this boundary crossed.
