I've slapped and pinched loli's butt numerous times before, but she did the same to me, and with her family members. She also squeezed my penis once and touched it with her foot a few times (pretending to stomp on it, then slowing down and pressing on it softly) and slapped my crotch area once (similar to what she did with her feet). She would also squeeze my nipples very often.
Would it have been okay to do any of the stuff to her that she did to me? She didn't mind when I did things with her butt (she'd laugh and try to get revenge on my butt) but I drew the line there.
