Forbidden Lesson: Stepdad Teaches Graduate Daughter a New Kind of Pleasure with Anal Bottle Punishment

The graduation party had been raging all night, but when I found Rin Kind stumbling near the pool, I knew she'd had one too many. Her brunette hair was damp, clinging to her forehead, and her laughter was slurred. "Time for bed, kiddo," I said, my voice firm but laced with concern. She giggled, leaning into me, her natural tits pressing against my arm.

"But Dad… I'm a graduate!" she protested, her words thick with alcohol. That's when the idea sparked. A punishment, yes, but one that awakened a forbidden pleasure within me – and, I suspected, within her too.

I led her inside, gently pushing her onto the bed. Her eyes fluttered shut as I began to unbutton her dress, the fabric sliding off her shoulders to reveal the submissive gleam in her eyes. I brought out the bottle, the cool glass a stark contrast to her flushed skin. A gasp escaped her lips as I lubricated it thoroughly. She was still so young, but desire was radiating out of every pore. I pushed it into her tight ass, feeling her tense up, then slowly relax.

"Harder, Dad..." she moaned, breaking the silence. Each thrust brought her closer to the edge, her cries echoing through the house. Soon she was begging for release, her body trembling with each wave of pleasure. I delivered, filling her with my cum, sealing our secret bond forever. The taste of ass to mouth felt like a forbidden fruit in my mouth.

Later, after she'd fallen asleep, I stood by the window, watching the sunrise paint the sky in hues of pink and orange. I was a changed man, forever bound to my stepdaughter by this taboo act, this electric secret we now shared. And I knew, with a certainty that both thrilled and terrified me, that this was just the beginning.
