I know there was a disappointing transition between 152 and 153. But I knew that anything I tried to draw that was sexual in nature, despite trying to make it as tasteful as possible, would be censored on WT. So I decided to not spend 50+ hours on an episode that would get butchered and decided to focus on aftercare instead. And given that cleavage and a 1/4 of Sam's butt cheek was too much in 153, I think it was wise to not draw the actual encounter.
So here is a sketch of some foreplay. I got this cleared through my manager to post since it's only considered "erotic." I would have loved to show their encounter in a wholesome way, encouraging consent and interactions in a realistic manner. Unfortunately, it wasn't to be.
But the characters stayed true to themselves. Charles was slow and patient. Sam was shy but eager. There was a lot of face-hiding from Sam and a lot of encouraging coos from Charles, whose only regret was that he had one condom with him (of course Sam doesn't own any). I might hire a writer to do some fanfic of the encounter.
