side nudity is ok as long as;
1) you see no nipples
2) you see no pubic hair
3) you can only see 1 butt cheek at a time
video = pretty tame actually
there are doctors video on youtube about breasts.
hard to fap too, but not research.
and i have found oral and vaginal research on youtube before on some mexicans profile.
i flagged it to be douche of the year awardee.
