What can I do about this? Unsolicited nudes

I had messaged the father of one of my sons friends as my son hadn’t come home yet and this friend messaged my other son who was at home that he just left and was on his way home

Well the walk would’ve taken 3-4 mins

It had been 20 mins since I was notified he left so I first asked my 1 son who was at home to message this kid see if he left the kid said yeah

Knowing how kids can be

I messaged the kids father and said hey just wanted to be sure if my son did happen to actually leave or if he was still by chance there? I was told he left and that was 20 mins ago. Thank you!

He said Yeah bitch

Then the father sent me pics of his penis and said lemme shut you the fuck up bitch dayyyyum! STFU GTFO

Sent me another pic of him flipping me off and told me to quit being a helicopter mom

I was offended and disgusted like WTF??? Who the fuck reacts that way??? What I …I …..I’m at a lost

Anyway my son did come home and apologized he stopped at the gas station for a sub and slushie 😬

What can I do about the dad sending me a dick pic? Anything???

For clarity my son is 14 years old the neighborhood is pretty safe, I just worry I lost a child, he was 6 …in a freak accident which has made me worry and stress a ton over my other 2 boys more so than I guess other parents idk 🤷‍♀️
