I showed my dick to my mom 2 times

hello. it the story of me 21M showing mom 42YO my dick in 2 occasions so mom is a very religious and modest women. she's a very beautiful tall blonde slim milf but she doesn't wear revealing clothes at all from a year ago until now had a strong fetish on her in the first time. was home alone with her and i was reaaaly horny with a strong boner and i had the idea of showing it to her. so she was on wod laying and i told her i had a problem with my penis then i directy bring it out of my pant. she was totally shocked and her face became very red and i was intentionally making it close to her head she probably never seen other dicks and i said i head a small pain in it so she told me to wear lose clothes in the second time. i was showering and i made it very erected and then told her to bring a towel. when i opened the door i made my dick appear so she can see it. she didn't look at it directly but iknow she saw it because she told me at least wear something and it not good to stay nude and that it. still have the desire on her if anyone have tricks to help
