Costumes on LetMeJizz
Most people picture slick convention-grade cosplay, but a fat chunk of this is cheap Halloween getups and dollar-store wigs yanked half off before anyone gets to the fucking. The outfit barely lasts, it's there to set a five-second mood then end up bunched around a waist. The dress-up is foreplay, the screwing underneath is the same as any other clip.
