Chester 5000 is an erotic comic set in a Victorian/Edwardian past, generally in the late 1800′s to early 1900′s.
The inspiration for Chester comes from many places, mostly the author’s love of vintage pornography like the Tijuana bibles, vintage erotic photography and erotic art from the 19th to early 20th century.

The Scientist

Robert is a hard working inventor and creator of Chester 5000. Robert has a very demanding job and little time for fooling around. When his wife, Pricilla complains about his work-a-holic tendencies and lack of attention to detail during sex, Robert decides to fix the problem in a way befitting of an Engineer.  Thus, Chester 5000 was born!

Pricilla

Pricilla inherited her family’s wealth and lives with her Husband, Robert in the countryside. Pricilla is a woman who knows what she wants, and she wants it often. When her busy husband first created Chester for her she was frightened of the idea of a cold, unfeeling machine. However she was soon won over by Chester’s Love, attentiveness, charm and er…other good qualities.

Chester 5000 XYV

Chester is the brilliant creation of a very talented Scientist and Engineer. He has many useful features and tries very hard to please. However, Chester is more than the sum of his parts. He is a sensitive lover, a wonderful listener, remarkably intelligent and loyal. Chester is much more than a hunk of slippery metal, it didn’t take long for Pricilla to fall madly in love with him.

Likewise, Chester loves Pricilla and would not let anything keep them apart.

Isabelle

Isabelle is a Widow. She inherited the small amount of wealth she has from her deceased Husband and lived a somewhat lonely life until Chester came along. Robert was good friends with Isabelle’s husband.
