Why is Gine okay with her husband cucking her son? Vegeta sr. is understandable, since he's a prick, but just seems odd that there's Goku fucking Videl, Bulma fucking Vegeta's dad, Chi Chi fucking Bardock, Gohan fucking 18, and so on, yet no explanation or continuity.
The prequel with Bulma and King Vegeta was better, because it was fully consensual. The forced sex here is too rapey; I could actually buy Chichi being a sexually frustrated housewife due to Goku's neglectful behavior, but I never got the vibe that she actually wanted to bang Bardock here. I'm not saying this was a full on rape, as Chichi probably chose to tolerate Bardock's advances and didn't have too much of a problem with them, but merely putting up with something isn't the same thing as wanting to do it. She doesn't even have any thought bubbles that show her desiring Bardock. Not that this comic wasn't hot, but it was too generic and cliche. "Oh, my son's wife is nagging me? She probably isn't getting any action. I'm gonna do her a favor by forcing myself on her!" Boring.
