8 XXX : bdsm

yeah, not ok. do whatever you want at home, but don't involve randoms unwillingly in your sex life.
And even if it isn't sexual a lot of people outside the community assume it is due to common portrayals... This would be like making out and groping in public; disrespectful to do something you know will make others uncomfortable. Try to find some conventions and clubs to go to for your crowds.
You have all kinds of cool shit going on here. The school girl thing. The pet play thing. The crop in the backpack suggesting impact play. The knees implying Domination. The bracers implying bondage. Exhibitionism. Impressive. Well done.
