Her younger loli form was definitely more arousing, but what I never got about this episode was how he apparently found the older JK version of her attractive enough to sexually assault her tits in her sleep yet refused to have sex with her until she turned into a loli. lol
She's still pretty god tier cute and pristine in her bustier JK form, even speaking as a hardcore lolicon, plus it would have saved him a fair bit of scrutiny from the circulating videos.
