She takes advantage...

Lena pushes her cock into your mouth slowly but firmly. Her hands on the back of your head. You moan softly trying to take it all in. Lena coo's at you

"Shhhh... It's ok. bad dreams happen..." she says as she begins to move your head up and down on her cock.

Her hard cock sliding into your mouth deeper with each movement, you struggle against her gently, not really wanting to fight her. You are taken in by the scent, the feeling of her hands on your head, the forceful nature of what is happening. You moan again, gently.

"Yes, you enjoy this. Being used by big sister." Lena says.

You move your hands up to her hips to steady yourself as Lena begins moving faster, thrusting into your face confidently. You taste a slight hint of precum and you suck harder. The thought of having another does of her girlcum becomes your only goal as you suckle and try your best to help her fuck your face.

"You're ... my little slut aren't you... just a cumslut for... sisters milk..." Lena says haltingly as she thrusts continuously.

You moan your response as you happily withstand her ****.
