Touch it

You can't deny the temptation, and your hand tentatively reaches for Martha's massive member. She lets out a soft moan as you wrap your fingers around it, feeling its warmth and hardness against your skin. The girth of Martha's cock in your hand is truly impressive.

"Stroke it. Slowly. Up and down."

Martha's breath grows heavy as you do what she says.

"Your hand feels so good around my big cock, step-bro! Isn't it very big?"

You gulp, feeling its size. You feel your cock harden even further.

"It is, right? Soo big."

"Does my step-brother's little dick get hard just by jerking off my cock? Does it turn you on that I am so much bigger than you?"

She takes your dick in her hand and squeezes it.

"Mmmmmh. How cute!"

Martha moans in your ear, and then her grip around your dick grows tighter, her strokes firmer and faster. You're unable to hold back a quiet moan, your cock throbbing in her hand.

"Good boy... Just relax and enjoy this. It's okay to enjoy it..."

"Look how much bigger my cock is. Yours is so... cute and innocent. Right?"

She giggles softly.

"Why don't you tell me what you think of my cock? How big is it? How much bigger is it than your little cutie here? Tell me, please!"
