Stepdaughter greedily sucks her father's hard dick wanting to get a mouthful of cum

I came home after lessons , my stepfather was lying on the couch, watching a movie and stroking his penis, not noticing how I entered the room... his swollen penis bulged out of his pants, and it really turned me on... the thought "why not suck Daddy's dick" flashed through my head, and I impatiently pounced on him ?
