Fantasy one bad incident

[phantomxxx]

one of the incident just happened in may,i just came back from college and was watching some television ,dad was out on an official tour,i just sat down and was talking on phone then suddenly i heard some courier guy ringing on the doorbell,i was just busy then i got shock of my life my mom just after a bath was wearing e loose petticoat covering her half body and breasts,her thighs were half visible.I was amused that how can a woman with good public image can be so careless!The courier guy was tensed and his eyes were wide open he was eyeing/lusting on her body her fair skin and healthy thighs were a delight to his eyes,finally after chatting carelessly she patted back into the room by swaying her ass...and i now started masturbating imagining her body and few encounters maybe inside i was wrong but i still couldnt control it,i would see her changing dress and would commonly sneak into her room to check her bra and panties.In the worst scenario i had chatted with the slum kids she visited,by inviting them and openly lusting on her body am i becoming pervert or something like cuck?i am really confused or is it natural,kindly guide me
