I found my sister with her friend and burst into the bedroom with his dick in the air

The boy was curious what his stepsister was doing with her best friend and why these bitches did not leave the room for so long. Yesterday he broke into their bedroom and found the chicks licking each other's beans! The sister said that he would tell his mother about her adventures and offered to join them in exchange for silence. Bro fucked the girls to the fullest and came all over his face. He wanted to quietly fap and was not going to hand them over to his parents, but since they called them themselves, what can he do?
