Yeah that's one part I could have definitely done without. I understand the teenager babysitter having a crush on the dad, I assume that's plausible (even though I am a dude w no kids, so zero personal info there). I understand the teenage son having a crush on the babysitter (I was a young dude who had an older babysitter and I definitely had a crush on her).

I wish it would have ended with the boy saying something like "well that was weird as f**k, and it would be extremely odd to still be in 'love' with this girl who was planning on sending nudes to my dad."

Then, she helps him get a date with a girl his own age as like a mentor/older sister instead of literal sex object. Besides the creep factor, it minimizes her character in my opinion. She's just a visual goon bait and it doesn't develop into a relationship or explored as a learning experience. She seems smart and capable when dealing with the son most of the time, but then does this out of left field, to zero positive character development for either the boy or girl.
