Hung daddy gets sucked by juicy lips of step son

Every night, I go to see my father as he gets ready for bed and every time he sees me looking at him, he takes his pants off and makes me swallow his giant dick.
He shoves his cock deep inside my mouth and I suck it with my lips and make his dick very wet. As I move my mouth over his dick, my daddy gets more horny and finally he lets go and cums inside my mouth and I swallow every last drop of his thick and stuck cum.
