So I am 19 and my mom is 43 and she is 5'9"and about 125 pounds and is really attractive.Ever since puberty I have gotten hard just being around her.But recently I have started to think about her when I masturbate and also I masturbate watching her out my window when she is on the patio smoking a cigarette or just on her phone.Nothing will ever happen nor do I want to.We are just not like that.She would disown me if she ever knew.In the last few months her and her boyfriend have been coming home on Saturday night and have sex.We share a bedroom wall and I think they try to be quiet but with my ear to the wall I can hear the bed squeak and my mom moaning.I simply cannot describe how unbelievably arousing this is.I am a virgin and to hear sex is unreal but listening to your hot Mom is indescribable.Sometimes,I will pre cum just watching TV with her.So of course I have to go to my room and take care of it.This is all true and I wonder how common this is.
