AV is full of mosaics and not erotic... Huh? Anal doesn't get mosaic...it's kind of erotic. Even if you can act like you're cumming, the twitching of your anus is real. When I was having this conversation at school, my classmate Nacchan overheard me. Hey, do you like buttholes? I'm interested too, Natsu. Would you like to come to my house?
