Spoilers:
Theme: Themen't.
Story: Lots of funny one liners, but this was mainly one part a parody of tennis ace, one part jokes towards? with? for? Choky. (also because tennis ace?)
I suppose it's doing well in what it's trying to do as a shitpost, but shitposts aren't quite long form media, even for the longest of youtubepoops.
You also made the bull Otis from the Barnyard tv show/movie?
Presentation: You used the camera well overall, and I loved my son, Aoba, with his realistic head, but some things were askew like the macaroni sex noises at the start that failed to line up with the dialogue, or pasting a link to an image for us to see at the end.
Creativity: There's always creativity in shitposting, but there's also only so much room if one stays too close to the inspo.
Overall Thoughts: As a shitpost goes, 5/5. As an overarching story/game? I can't be that generous. Your mpreg is noted and appreciated though.
