What would you do if you walked into a room and your mom or sister was in the middle of a gang bang and blindfolded so she wouldnt see who was banging her.
i think i'd walk out haha, i've walked in on my mum while she was masterbating... that's enough never mind a gangbang!
One could say "it's my mom/sister" but then others will say what she doesn't know, won't hurt her and go bust a nut...
I would most definitely walk out in anger, although I think I'd try and get a quick glance just to see what the fuck is actually going on!!! Considering I'm 41 so my mum is getting on a bit!!! I'm not too bothered about what my sister gets up to.
