I know you can do better, so saying 'it's literally bad fan service, that's how its supposed to be' is no excuse. It's even worse! You give every cuddle, lusty aside look, and sex joke a good, IC reason to exist. Taffy and White love their 'mommie', Musashi and Jersey are both proud of their looks and see the other as a threat, yet still appealing.
Let me put it this way: An animation company that spends time and resources on a 15 min short for a DVD sale that's literally nothing but the characters in swimsuits could have spent that time and resources developing the characters, sex appeal included! It's a
waste, and so was that. You
wasted your time and creative effort, and frankly anyone with an ounce of standards in writing should feel the same.
Is it still funny if it costs you a reader?
