[HUNTB-617] Face sitting in seconds as soon as you open the front door! When I came home from school and opened the front door, my constantly frustrated step-sister suddenly pushed me down and face-sitting! His crotch is rubbed against his face and his erec (Censored)

My new step-sister seems to be always horny and seduces me at every opportunity. Although they are not related by blood, they are siblings, and one day when I got home from school, my sister-in-law, who was waiting at the entrance, suddenly forced me to face sit! Even though I'm about to suffocate, my crotch is full! When he saw me like that, he grabbed my erect dick as if it was his chance! Suddenly face-sitting is cowardly. I can't stay rational!
