I did train my art on some pron scenes (cannot spell the word correctly, you seem to get trouble with Patreon...) back in the day, having the production for LUST comic 1 in mind.
This is traditional graphite on paper, scan, enhance digitally + digital red color with Photoshop.
I do like the perspective on the right & the details on the dick: really promising for all that was about to come next, heh!
I corrected a bit the light here & most of all his haircut, much too thick originally, haha! But yeah, nothing's more thick than what he's playing with, right?
