so when it comes to tits you're only familiar with hentai.. have you considered drawing pictures of what you imagine are the best of tits? much like fake tits, when drawing them for yourself, you can make them look extremely like anything other than actual tits. why not 8 of them? make her face one, too. put a couple on the back to grab when you're hitting the pair you used to replace her vagina with from behind. or, and this may sound crazy, go to a porn site to look at naked people instead of whatever this is
