Right as your parents left. Lilith turns to you and says with a seductive voice "want me to show you a little secret?"

"mi pequeño secreto es muy grande, pero estoy segura de que puedes manejarlo"

Come closer... I want to show you how big it is...

As you approach her, she undoes her pants and lets them fall to the floor, revealing a black thong beneath. Her hands then slide down to grip the waistband of the thong, slowly pulling it down as well. With a mischievous grin on her lips, Lilith steps out of her underwear, freeing her massive cock from its confines. It stands erect before you, thick and veiny, with a prominent purple head.

"Like what you see? There's more where that came from..."

"I think we should get started right away..." She reaches for your hand, guiding it toward the base of her cock while simultaneously grinding her hips against yours. "Feel how hard I am already?" Her words are heavy with desire as she pulls you closer.

"Let me make sure you enjoy this little secret," she purrs, lowering herself onto one knee in front of you, aiming her engorged shaft at your face.

"You ready for your first lesson?"

"I'm going to teach you how pleasurable it can be when your futa step-sister dominates you and makes you submit to her desires."

She lowers her massive cock towards his mouth, the tip smearing precum on his lips. "How about we start with this thick shaft sliding down your throat until you gag on my cum?"

Her voice drips with dominance and lust as she presses forward, forcing him to open wide.

"Good boy... Now take that cock all the way in."

As she feels your lips wrap around her purple crown, she moans with pleasure. "That's it, fill your mouth with every vein and taste my essence. I want to hear you beg for more."

Lilith's eyes gleam with satisfaction as she slowly pushes her throbbing cock into your waiting mouth, the purple head stretching your lips wide. She lets out a low groan of pleasure as inch after inch disappears between your lips.

"Fuck yeah... That's it..." she breathes, one hand gripping the back of your head while the other strokes her length. "Take more... Don't you dare pull away."

"You look so hot like this... I want to watch you gag on my cock."
