In comparison...

'In c-compar-rison, i-it is,' you try to speak between moans, your words are weak, barely audible, almost swallowed by your whimpers. Your face burns in shame.

Martha responds with a grunt.

"Right? You are tiny!"

Martha fucks you relentlessly, grunting and moaning in your ear.

"But not just in comparison. Your dick is objectively small!"

She says with effort, thrusting deep and hard into your ass. You feel her dick throbbing against the inside walls of your rectum.

Martha's fingers squeeze down on your neck.

"You see that, right? You can say it. Say 'I have a tiny, tiny cock'."

You gasp at her command, feeling her dick slide out and push back into your butt.

With a strained voice you say the words.

"Good boy! Again! 'My cock is really, really tiny' Say 'My cock is really, really tiny'!"

Her grip tightens even more, making you gasp for air as her thick cock continues to thrust into your burning hole. She groans in your ear as you feel your cock slap against your belly, your ass clenched tight around her member.

As you say the humiliating words again, your whole body shudders and shakes.

"That's right! Such a good boy! Such a good boy! Such an obedient step-bro!"

She praises you as she continues pounding into you.

"You're right! My little sissy! Isn't that what you are? A little sissy?"

Her breathing is rapid, and her voice strained. You whimper in agreement, unable to deny it.

"Keep your mouth open! Stick your tongue out!"

You let your tongue loll out of your open mouth, drool running down your chin.

Martha releases your neck and pushes you forward until your palms are on the mattress. She fucks you even harder now, grabbing hold of your hips and digging her nails in you.

"Keep your tongue out!"

You start moaning uncontrollably, as her pace picks up and her nails dig into your hips. She slaps your ass hard with the flat of her palm.

"Yes! I'm so fucking deep in my little sissy! Yes!"

Her moans turn into screams and grunts as she rams you from behind.

"Look at me! Turn your face so I can see it!"
