AlwaysOlder - A Hard Day's Work - Western Adult Comic

Jason and Lana argue more than most siblings, but when they start arguing about gender roles back in the 1950's, things get a bit too heated. With just a few offhanded wishes, they're both thrown into the past and forced to live a day as the opposite sex. The siblings turned husband and wife will have to understand how the other half lived back then if they ever hope to change back...but will they even want to?
