If you are into adult comics, a great place to get started is with Fansadox ( collection link ). Great stuff that should provide you with hours of entertainment!
Outside of Fansadox, John Persons creates his own set of comics ( site link ). This torrent contains what I consider to be his two best comics (and its the only two I actually have):
All kinds of sex acts are included, but the highlights are the deep throat gagging images. Really classic stuff.
You can also find: blowjobs, anal, doggystyle, interracial, creampie
Love bellies? So do I! Stretched, poked, and yes... punched !
