This is a short oneshot in the same vein as Portball! by the same author, and it shares some similarities to the author's big series, Yomeiro-Choice.
I'd say this is not quite as insane as Portball!, though really, that isn't saying much; Portball! had a character who ran around giving blowjobs to players on the other team in order to win a game, but there's no "actual" sexual content going on in this one. Still, it does go pretty far, so if you have no tolerance for ecchi stuff, then run far, far away.
Like the author's other works, this has numerous references to famous
manga/anime series and has about as much logic as one of the stranger episodes of Dexter's Laboratory, but with lots of sexual references.
I really don't have a lot to say here that I didn't already say in my Portball! review. These two oneshots share the same insane, intentionally stupid spirit, but they're different enough that if you liked one, you'll almost certainly like the other. I hope to see some more short stories from the author like this in the future, because being a short story gives a lot of freedom for crazy endings without having to revert back to the status quo, but unfortunately she (yes, the author is a "she") seems to be too busy with the monthly Yomeiro-Choice for now. Oh well.
