Bases around Mars are collapsing to some mysterious phenomenon. Then a little girl who is actually a robot turns up at the airlock. Clearly the best way to search her is to violate her orifices. You’ll find no argument from me there. It sort of starts to go downhill after that though.
It’s that old standby of ABP doujins, the 30 yen sale! Isuzu isn’t a big fan of the female staff being taken advantage of for only 30 yen (converted to 30 cents in script), but she’s soon convinced of the advantages. Or they just rape her until she’s comatose. Same thing.
If there was such a thing as practical sex ed. classes, you know that there would be guys that were so ugly that nobody wanted to be paired up with them. And girls that were so stuck up that they thought that nobody else was good enough. I imagine these two would get paired up a lot.
And if the teacher were to then choose to have the whole class gang bang the stuck up girl to teach her “the joys of sex”, then so much the better.
When your girlfriend isn’t putting out, clearly the best choice is to rape her best friend. Well, maybe not the best choice, but it’s a solid option. Then tell your girlfriend that her friend got you drunk and seduced you.
Then sell them both to your mates for a gang rape. Nice.
