Kimomen demo Kyokon nara Meimonkou no Ojousama wo Senyou Harama Celeb Bitch ni Dekiru!

Thanks to the scarcity of students in a country of declining population, an ugly stupid guy was able to get into a prestigious school. Meanwhile, girls at this school were inundated with propaganda to have sex as early and often as possible.
Result: a harem of 4 highly bred rich young ladies and a dumb luck, big dicked loser in the middle
Every day is a sex party!
"kimomen" the protagonist bangs the heck out of super popular, wealthy bitches.
For country and for selfish lust, beautiful, smart, elite girls
fall over each other to ride his manhammer!
