Is this sexual/inappropriate behaiviour on my stepmothers part or am I overreacting? Serious answers only plz!?

why in the hell is your step mom playing basketball with kids in the first place.also you need to get erection into those school books so you can get an education.of corse what your step mom is doing is wrong / you'll need to inform your dad about what your step mom is doing before things get out of hand .and leads to something that could get both you / her in trouble.
